I graduated and found out I'm $200,000 in debt - nefitty

It is the ultimate responsibility of the person taking out these unsecured
loans to figure it out. The school (UConn) may made it available, and can
certainly be better about educating their students for success, but the author
is the one who took out the loans.
The problem, as I see it, is they cannot "give back" their degree, because
they've already gotten the learning out of it. Should the lenders eat the
money because the lendee didn't pay enough attention?
Ultimately, this is a structural issue. However, the colleges are indeed
catering to people's money and desires. We all only have ourselves to blame
for this, because we buy into and develop the "American dream" of college and
a picked fence in front of a house we own.

Sitzfleisch: The German concept to get more work done - sonabinu
http://www.bbc.com/capital/story/20180903-to-have-sitzfleisch---its-a-professional-compliment
======
wirrbel
As a German I spent an abroad term in Canada, so here as a grain of salt the
difference between German and the work ethic across the pond.
9am: I arrive in the lab at around, sit at my desk and set up my stuff.
Unfortunately there was is one around to start the day with a coffee break.
10am: Canadian lab mates arrive, sit at their desks and go on facebook. noon:
After spending three hours reading papers, fitting curves to data, etc. I get
hungry. I go to lunch with a Dutch person I met in the building a couple of
weeks ago. 1.30pm: Back at my desks. Through the towers of take away junk on
my lab mates desks, I can see they made some progress on facebook. 3pm: I try
to convince some of my labmates to go for the coffee place within the building
to have a short communal coffee break. Of course everyone is too busy and
cannot socialize, except for the post-doc from india (who does not facebook)
3:45pm: Back at the desk, wrapping up the results of my day, my lab mates are
still "working". Next morning, they will tell me they stayed till 8pm in the
lab and how increadibly busy they are.
Granted, in between visiting facebook and skipping communal lunch- and coffee
breaks, they got some work done and I don't claim I delivered more results in
terms of research and learning "output".
Yet I think it summarizes my and the experience of other Germans quite well.
In Germany there is much more focus on not working long-hours but spending the
hours you work productively. A German workday of an office worker is limited
to max. 10h per day by law and my employer follows that rule religiously. Many
colleagues contractually have 35 h work weeks and working 40 h requires a
permit from the worker's council. If you are sick, you stay at home on sick
leave, you join your colleagues again when you are better. American colleagues
working here for a year or so as part of their assignment quite often start
out to send an email that they are sick and will work from home. If you are
sick, why do you work? Your job now is to get better. Quite often, breaks for
lunch or coffee are started and ended together. Only few people come into the
office with half-liter coffee mugs to consume on their desks.
Obviously there are exceptions to the rule, and office cultures of individual
companies may differ. My current company's culture is very German if you
arrive before 8am, you might be welcomed with handshakes by your colleagues.
~~~
lnsru
I would say, foreigners always do more than locals. They feel, they have prove
something, maybe less social contacts too. I observe the same behavior like
your Canadian lab mates with my young German colleagues. All day long sitting
in mobile Facebook or drinking coffee for 30 minutes every 2 hours. Germans
aren’t majority among department’s top performing people.
Edit: it’s IG Metall company and you can’t fire people easily. So low
performers accumulate over the time. Talents come and go.
~~~
foepys
> So low performers accumulate over the time.
This is an incredibly offensive statement against unions and I want to see
some proof from you for this. All large corporations in Germany have unions
and Germany is still one of the world's economic powerhouses.
~~~
dmichulke
Sometimes statements of facts may seem incredibly offensive. Others should be
able to mention those in a related discussion, even if offensive, because
otherwise the discussion is biased.
I use the word "fact" above because I think it is obvious that if firing is
hard, low performers accumulate. I'm happy to elaborate if you wish.
~~~
Firadeoclus
So where do low performers come from and where do they go to when you fire
them? What is their flow through the economy? A fired low performer will still
look for, and likely find, another job. The assumption there might be that
they will learn and try harder, but whether that is the actual effect is much
less obvious than you might think.
It's also not obvious at all that churn is good for overall productivity of an
economy. Can you show that making firing harder or easier causally affects
average productivity (or the productivity distribution) in a specific
direction?
------
sidstling
Great headline, terrible article. It mostly talks about German words and
almost nothing of German work ethics. The only interesting bit is around the
end where it quickly skirts over the fact that you need to make employees
realize they are unproductive before you can work on their behavior.
All the other stuff is just meh. I mean, the language analysis isn’t even very
good, or in depth, with terrible half-assed English translations.
Basically, don’t waste you time reading this.

Never heard about this “Sitzfleisch” thing living in Germany many many years.
Young people don’t use it. Maybe it’s some old people thing?
~~~
pragmatick
I never use it but know the word and usually when I hear it it's more
negative, e.g. when you have guests who won't leave you might say that they
have Sitzfleisch.
~~~
hodgesrm
This is the only meaning of Sitzfleisch I have ever encountered. It's not a
compliment at least in our house.
~~~
btschaegg
Interesting. I think I only ever heard the term in context with politicians
that that were elected "too many times" by someone's standard. There, it
_certainly_ isn't meant positively -- the funny thing is that this goes rather
well with the phrase mentioning Angela Merkel at the beginning of the article.
There are more and more voices now that would prefer someone new taking her
post.
------
mrleiter
Experienced the same thing in Austria: I'm from the most western part, which
mostly has alemannic and rhaeto-romance influence and the work ethic is
"german". You have Sitzfleisch, I go to work/university at 7am and after maybe
5-10mins of relaxing, I get start working/studying. I take a break at midday
and a short one in the afternoon and leave around 5.30/6pm
People at the very eastern end of Austria, like Vienna, are far less "German".
Their work ethic is much more relaxed, and like user _wirrbel_ pointed out,
they stay late to work, simply because they start later and get less work done
in the same amount of time.
~~~
austrianguy
Very eastern end Austrian here:
Working from 7:30am to 5pm. Cannot understand the German work ethic and the
often seen German workaholics.
You work to live, you do not live to work!

TurboHaskal
I’ve been working in Germany for a decade and I’ve unfortunately never
witnessed this so called German work ethic.
I do hear about it a lot specially when talking about my home country and
ironically during coffee breaks.

PacifyFish
I love German words.
Disappointingly this article skirts around the obvious English translation:
“ass-in-seat.”
~~~
AstralStorm
English has a slightly more general word. It is "grit". The ability to work
continuously and without being distracted. Perseverance of effort. Ability to
execute on a long term goal efficiently.
~~~
ThePadawan
I would also consider "grit" to be a very appreciative term. "Sitzfleisch" I
would consider more neutral, a person's property rather than a virtue.

Related, the book "Dreams of Earth and Sky" by Freeman Dyson:
"Why did [Oppenheimer] not succeed in scientific research as brilliantly as he
succeeded in soldiering and administration? I believe the main reason why he
failed was a lack of Sitzfleisch. Sitzfleisch is a German word with no
equivalent in English. The literal translation is “Sitflesh.”

" _Before employees can work on increasing their productivity, they need to
realise that they are underproductive_ "
This is seriously flawed (and over-generalizing). This basically assumes that
the cause of underproductivity lies with the employee. Where are the arguments
which are supporting this??
~~~
falsedan
If an employee is unproductive because they are unmotivated, they do have the
self-empowerment to say “this project isn’t motivating for me, let’s reassign
me/plan for a more motivating project next/go over what the stakeholders need
from this”. If they are lacking the skills required to succeed at the project,
they can go for training/get more experience from completing a similar,
smaller project. And if they are apathetic and feel like they can avoid
redundancy by putting in the minimal effort, they can look for a new job.
Sometimes the cause is external, like poor & changing requirements or wishful
planning, or a bad personal relationship with coworkers, but even then the
employee can feed that back to management. If they choose not to act on this
feedback, see the ‘apathy’ option above.
Source is self-management on solo projects.

Pandalized: Sites Negatively Impacted by Google's Panda Update - rlander
http://www.pandalized.com/
======
bcrescimanno
Does it make me vindictive to want to see most of these sites never "recover?"
This basically reads like a list of sites that, up through the "panda" update,
I would mistakenly click on, get pissed off, and go back looking for a REAL
result.
Many of these sites were basically duping people into giving them ad
impressions with thin, stale (and sometimes stolen) content and making
people's lives more difficult. Kudos to Google for the first time in many
years making a solid stand against obvious gaming of their search results.
~~~
Turing_Machine
_I would mistakenly click on, get pissed off, and go back looking for a REAL
result._
Precisely. Virtually all of these are pure crap.
I'm sure there are some legitimate sites that became collateral damage, but
these aren't them.
------
WillyF
It's pretty interesting to see just how drastically Panda affected some very
large sites. Most of the sites shown are the kind of sites that Panda was
designed to deemphasize in the search results. It's what Google got right with
Panda.
What it doesn't seem to show is what Google got wrong with Panda. One of my
sites lost 30% traffic on the day Panda went live, and it hasn't recovered.
It's an extremely high quality site that I've put my life into for the past 4
years. I've tried a number of different things to recover, but so far I've had
no success.
My strong hunch is that it's a duplicate content issue, but I can't be sure.
I've tried using rel="canonical" and reindexing parts of my site to no avail
Google hasn't offered anything to help. I've been through their guidance on
building high quality sites:
[http://googlewebmastercentral.blogspot.com/2011/05/more-
guid...](http://googlewebmastercentral.blogspot.com/2011/05/more-guidance-on-
building-high-quality.html)
It doesn't really help when you already have a high quality site and still are
penalized. I'm pretty confident that Panda improved the overall quality of
Google's SERPs, but they definitely made some mistakes. It sucks when you've
lost thousands of dollars in revenue because you're one of the mistakes.
~~~
WalterGR
My story is almost _exactly_ the same. The only difference is that my site was
hit not by the original Panda update, but by the April 11 update ("Panda
2.0".)
There was definitely collateral damage. Unfortunately for owners of such
sites, since Panda did penalize several huge sites that people hate very much,
it's viewed as an overwhelming success.
Small site owners are burning the midnight oil, posting to the "official"
Google Panda thread, and getting no feedback from Google.
~~~
antimarketing
Google has given precise and clear signals of what to do with other releases
from other teams, the Google Panda team is not directly responsible for
rankings. The information is purposefully fragmented among the different
releses, blogs etc.. of different teams. Because that is the way Google is
structured, works and also because they want to avoid giving stupid people too
much power by providing an easy "how-to" guide to rankings.
You need to be a pro. marketer and know a bit about programming to keep up
with Google's recommendations. I have done this, I simply do not want to share
this information here where marketers read and make thousands or millions off
it, but I would be glad to share that information with small site owners
privately for free, one on one. No marketing orgies allowed! :)
Simply stated, if you would for the next month study everything that Google
has released the last couple of years (80+ hour work wweks) you would realize
where they are going in the next couple of years not only theoritically, which
is very useful, but also with practical steps in how to become a friend of
Google.
The reason that Google does not produce a even more straightforward guide to
SERP / SEO field than they do right now (to lazy to link to it, because it is
not that important right now) is that most marketing people are dumb and
simply want to build an automatic system that generates money for them without
hiring someone or fixing stuff themselves. I think they, meaning Google,
consciously want to keep the human element alive and active in search engine
marketing right now, therefore you saw Panda, you saw Google+ and you will see
a lot of other things down the road as well.
You have to understand that Google sees itself as educating, if not
enlightening marketers with their activites as well.
It might surprise you, but most marketers are ignorant of how their field
really works. Having attended tons of seminars and a few conferences to boot,
they can not even grasp simple technological innovations like HTML5 Video,
even if it is explained to them nice and clearly many, many times.
So from Google's stand point, they want to make this learninge xperience slow,
step by step, and like a puzzle for a child.
(I am leaving out all the criticism of Google that I have and portraying it in
a neutral light for now)
~~~
WalterGR
_I would be glad to share that information with small site owners privately

Panda hit my site almost 5 months ago. Though I've made lots of changes, I'm
not seeing any recovery. So clearly I'm doing something wrong. As a small site
owner, I'd be ecstatic to receive any advice you can share. My email address
is [email protected].

bmatheny
I'm just going to point out that this site is hosted by wisegeek.com, a site
that was hit hard by the panda update (see
<http://www.quantcast.com/wisegeek.com>). Although the data is accurate, I
wouldn't feel sorry for most of these sites.
Full disclosure. I used to work for ChaCha. I am no longer associated with the
company, but in my time there I know a lot of time/effort/money went into
producing original content.
An aside. Pandalized was using a domain proxy so I connected to port 80 via
telnet which gave me back the following banner (which gave up the hostname):
Apache/2.2.8 (Debian) DAV/2 SVN/1.4.2 PHP/5.2.5-3+lenny2 with Suhosin-Patch
mod_ssl/2.2.8 OpenSSL/0.9.8g mod_perl/2.0.2 Perl/v5.8.8 Server at
strongwiki.wisegeek.com Port 80
~~~
troels
Interesting aside. I didn't even know domain proxies existed, although I'm
sure that's common knowledge, and a fairly obvious thing to create.
Can you walk me through the way you discovered the hostname? If I `telnet
pandalized.com 80`, I don't get anything interesting back.
~~~
troels
Ah .. I got it. telnet in, then print some garbage, causing the server to
respond with an error. This comes from the main Apache instance, rather than
the individual virtualhost, and that has the hostname you mentioned. Clever.
------
rlander
Just an aside: the original title before it got edited by HN mods was "Yes,
There Are Sites Recovering From Panda".
I posted this because, although a lot of the sites affected by the algo update
were junk, there were a few casualties that did not deserve it.
I hear a lot of people asking wether it is possible to recover from the
penalty and it appears that, although AFAIK no site has been able to recover
100%, a few like Hubpages (which _is_ legit enough) are slowly recovering. [1]

------
_delirium
On the plus side (for me), some of my niche hobby sites that have information
on a few static HTML pages, without much monetization or SEO effort, have
gotten significant rankings boosts lately. May or may not be due to Panda, but
did happen about the same time.
------
thirsteh
And pretty much all of them are a collection of poor content. Good then.
~~~
TomGullen
Yup, totally agree
------
TomGullen
Looking through the list, I see a lot of junk websites I don't want to
recover. Most people who seem to be complaining about Panda have really bad
websites. Most people wont even give you their URL after moaning about it for
a good few minutes. Perhaps it's time for them to change their strategy. I'm
sure there are legitimate 'victims' but I'm yet to see one I sympathise with.

Human-powered Q&A/search. You ask a question, a human gets paid a pittance to
answer it. They are focused on mobile now (text a question, get a text back

timcederman
Panda killed rankings for a lot of my personal sites that I don't update
often, but still have a lot of content on them (that I created, not junk). One
of them seems to be actively excluded from search results now.
As an example of the ridiculousness of the new algo, try searching for
"shopsquad" (a friend of a friend's startup). The official site had to
purchase an ad to appear in search results. Why?

Profit sharing is like someone renting out a house and giving you a percent of
the rent. If they sell the house, or if no one rents, the gravy train stops.
Equity is like someone giving you a percent ownership in a house. It won't put
money in your pocket now, but you'll get paid when the house sells, assuming
it ever sells, and for more than any mortgages against it.
------
gimo4000
Equity is shares in the company.
Profit Sharing is a portion of the company profits.
Profit sharing at my company would not be worth very much. But Equity in 5-10
years could be worth a small fortune.
At a company that isn't a small startup profit sharing could be huge.

CeramicSpeed’s Driven Concept Might Become the Most Efficient Bicycle Drivetrain - untangle
https://www.bicycling.com/bikes-gear/a22092182/ceramicspeeds-driven-concept-might-become-the-worlds-most-efficient-drivetrain/
======
woodruffw
As mentioned (and slightly buried) by the article, the really fascinating part
is that we _already_ have consumer bicycle gears that deliver 97% efficiency:
a Dura Ace groupset is expensive compared to the stuff you'll get at Wall-
Mart, but they're sold at pretty much every cycling store. I wouldn't be
surprised if the Ultegra and 105 (Shimano's next two groupsets by price) were
nearly as efficient as well.
2% is nothing to sniff at in cycling (people pay thousands of dollars for that
kind of advantage), but there are other factors as well: resistance to stress
(sprints), ease of maintenance and service, and weight all factor into the
utter dominance of the current groupset design. It'll be interesting to see if
CeramicSpeed can advance their design on those fronts.
~~~
mrob
>2% is nothing to sniff at in cycling (people pay thousands of dollars for
that kind of advantage)
2% is nothing to sniff at only if you're hampered by the arbitrary UCI rules.
By far the biggest factor in cycling performance is air resistance, and the
obvious solution (fairings) is banned. The UCI has been disastrous for bicycle
technology. Most high-end buyers like to pretend they could compete
professionally one day, so they abide by the same rules, which means there's
no incentive to develop truly fast bikes.
The UCI rules should allow any safe design, and avoid giving an advantage to
richer teams by setting a price limit (bicycles are already required to be
commercially available).
~~~
jdietrich
Fairings aren't as useful as you might think in most circumstances. On an
upright bike, they need to be enormous to offer an appreciable benefit, which
makes them heavy and difficult to control in crosswinds.
The optimum solution is a recumbent bike - by going feet-first, you can reduce
your frontal area by more than 50%. With a much smaller frontal area and a
much lower center of gravity, a tail fairing becomes a practical proposition.
Fully enclosed recumbents can achieve phenomenal results in the right
conditions (Sam Whittingham's 91km hour record, Andy Wilkinson's 41 hour
LEJoG), but they immediately become a handicap with any sort of gradient
because of the ~20kg weight penalty and they're unbearably hot.

Recumbents are cool and much faster in some situations but pro cycling exists

Recumbents have been banned by the UCI since 1934, so that ship has sailed. If
we had seen recumbents on the Tour de France for the last eighty years, they'd
probably look cool and upright bicycles would look weirdly old-fashioned.

I use a single speed bike at the moment. Not because I hate gears but because
I’ve never had a geared bike that didn’t constantly click on the outside
gears. It drove me crazy trying to tune them perfectly and never succeeding.
Forget increased efficiency. If a new design emerges that accommodates gears
and is simple to tune properly, then sign me up. No idea if the design being
discussed could offer this.

Have you tried out a bicycle with an internal hub gear? I don't know how loud
they are, but you shouldn't have any chain binding issues (and you could
probably run a belt if you wanted).

Continental system was NLA; they replaced the whole thing with a Gates Drive
system which is amazing.

If this drivetrain achieves its claims I will be very impressed. Shaft drive
designs have been around for as long as chain drives; and they have never been
as efficient. So mush is lost in the torsion of the shaft. A 2% increase in
efficiency is an absolutely massive gain. The cycling industry is littered
with flashy looking innovations that don't live up to the hype. The basic
design of a diamond frame and chain drive has not been improved upon for over
100 years.
But every now and then there are innovations that acually take hold. For
example, the slant parallelogram derailleur, hydraulic disk brakes, suspension
(for mountain bikes), and recently narrow-wide front chain rings. We shall see
how well this drivetrain goes.
~~~
jacquesm
Shaft torsion does not lose you much energy, it mostly acts as a torsion
spring: whatever you put in you will get back. The shaft will only warm up a
tiny little bit from the amount of energy that it will lose during a single
cycle.
Suspension _does_ lose you a lot of energy, which is why you'll never see it
on road bikes.
~~~
usrusr
Springs are terrible when driven by biological "pistons". Applying a certain
amount of force is much harder in some phases of the pedal stroke cycle than
in others and springs would make it impossible to go easy when you want/need
to.
~~~
jacquesm
It is a _very_ hard spring, not something squishy like front fork suspension.
The biggest downside would be eventual wear of the driveshaft, the losses will
be very low.
Note that almost every part of your bike acts as a spring in that sense, the
frame flexes a bit when you pedal, as do the cranks and the shaft. Even the
spokes in the rear wheel act as springs transmitting the force from the hub to
the rim (which is one reason why they are oriented the way they are, that way
they pull the rim along rather than that the spoke gets bent, the spoke is
stronger in that direction).
~~~
usrusr
Everything acts as a spring, and performance bicycle engineering goes to great
lengths to make them as as hard as possible. Frame flex under pedaling load is
measured, optimized against and a driver of buying decisions. Replacing the
chain with something more springy? Good luck in that market.
~~~
jacquesm
> Everything acts as a spring, and performance bicycle engineering goes to
> great lengths to make them as as hard as possible.
Indeed. So if you use a shaft to drive the rear wheel that would definitely be
part of the equation, I note they are using a hollow carbon fibre tube, which
in that particular dimension is likely not ideal for the application unless it
is given some more cross section. Even so, it is an interesting development.
> Replacing the chain with something more springy?
Chains stretch quite a bit, you'd be surprised.
~~~
mrob
"Chain stretch" is usually slang for chain wear. The chain gets longer as the
rolling elements wear down so people call it "stretch" even though the metal
isn't stretching. The actual stretch under load is very small.
~~~
jacquesm
I'm aware of the difference, but thank you anyway.
You can see the effect for yourself if you lock your rear hub and proceed to
push down on the pedal (you can see it because the pedal is a nice long
indicator effectively multiplying the distance the chain stretches).
A bit nicer setup is a micrometer at the end of a fixed section of chain with
a weight attached.
Chain _does_ stretch. About 1.5 mm under full load.
That's why you want chains with solid pins and solid plates.
What you are talking about is chain elongation as a result of wear,
essentially the accumulation of slop in the bushings the pins go through.

Very nice concept, I really like the fact that the casette is gone because it
occupies a lot of space leading to substantial weakening of the rear wheel
(the width of the hub where the spokes attach is a very larger factor in rear
wheel strength).
That gear does look like something that would do well in a meatgrinder, and
given the fall-out over just having disc brakes on racing bikes I don't think
that would pass inspection for road bike racing.
10 points for out of the box thinking though, a cardan driven racing bike is
very clever.

_The system would have to be pretty intelligent to know how fast the system is
moving. It’d have to be pretty smart to know how fast it’s moving, which tooth
track to select to make the shift happen. Would you have to back off to shift
under high load?_
This reminds me of some newer automatic transmissions that use dog clutches,
like a manual one, relying on sensors and electronics to do the
synchronisation --- there is a very noticeable (and unpleasant) jerk in the
shifts, since it has to match the speeds precisely, and automatically reduces
throttle to do so.
Of course, with a human providing the power directly, that's not really
possible. I suppose you could add a "shift light", but IMHO that's just
overcomplicating things...

They mention something about an electronically assisted shifter. Doesn't that
defeat the whole point of a (non electric) bicycle?
~~~
jdietrich
Not really. All three of the major manufacturers offer electronically-
controlled derailleur gear systems. It offers minor aerodynamic benefits and
more reliable shifting performance with no real weight penalty. The battery
adds about 60 grams and the derailleurs are slightly heavier, but the shift
levers and cables are significantly lighter. That battery lasts for about 1000
miles of typical riding, which is more than enough for the target market of
racing cyclists.
The inconvenience and cost of electronic shifting isn't a good fit for leisure
and utility cycling, but it makes sense in racing where every marginal gain in
performance is valuable.

> A stock Dura Ace drivetrain returned about 97-percent efficiency.
Does anybody know the numbers of efficiency in fixie and single speed
bicycles? I reckon they should be better given the absence of a derailler? I
tried to search for it, but couldn't find numbers.
~~~
21
Another article on this technology stated that the efficiency gain comes from
there being only 4 points under load versus 8 points in a chain with
derailleur system.
A fixie also has only 4 points, since the derailleur is gone, so it's
presumably more efficient.
But the big problem is that there is also an efficient human cadence (I think
around 100 RPM), and a fixie has a massive problem here. So overall, a fixie
is massively more inefficient. Which I guess is no surprise, cycling
competitions are run with geared bikes, not with fixies.
~~~
bennyelv
This doesn't sound correct to me - the derailleur is on the "slack" side of
the chain so is never under significant load.
The only load is that required to pull the chain back from the crankset under
enough tension to stop it from drooping, which is provided by the spring in
the derailleur cage.
All the load in the chain system is between the cassette and the chainrings on
the top.
Perhaps a link to the article will reveal more? There's a lot of BS in bike
technology, so I'm automatically sceptical!
~~~
21
Maybe load was not the appropriate word to use.
Smith explains that that friction in a chain-based drivetrain is created
largely at the eights points of articulation, where the chain bends around the
chain ring, cassette and pulleys.
"Any time a chain articulates, friction is created. And any time it
disengages, friction is created," Smith said. "When you think about pedaling
95rpm, you are looking at 40,000 stiction points a minute."
In the DrivEn system, those eight points are replaced by four points, each of
which rotate on ceramic bearings. The chain ring's teeth and cassette's cog
engage with the bearings on the shaft, which itself spins on bearings.

Ouch. I very narrowly escaped that (but did break my leg :( ). On intermediary
'sports' bikes and mountain there typically is a guard ring mounted on the
outer gear ring to mitigate some of that risk. Most road bikes don't have them

As someone who learned ML the "traditional way" I both like and dislike it.
I like that I can quickly learn about advanced models since I already know
about / can infer the intuition / mathematical details myself most of the
time.
I dislike it because it's almost all handwaving. The way things actually work
aren't really explained (other than at a high level) so either you're stuck
with a wishy washy understanding or you will read the paper yourself.
But for some of us "in between", we're not satisfied with the layman's
explanation, yet the paper is too formal to digest. I think there's an element
of survivorship bias there, where some people just give up because they're not
getting the explanations they're looking for.
Those who are smart enough to understand papers on their own can do fine,
because they'll take the course as-is and just use it as a guide for what's
new and fresh. Those who don't know what the heck is going on (and don't care)
are happy with "plain English" explanations without looking any further.

AOL chief cuts 401k benefits, blames Obamacare and two “distressed babies” - rsobers

for example, and that's also super-expensive.

We have had similar discussions in our own company, which is much much smaller

are try to figure out how we can continue offering great benefits but we'll
probably have to make a change. Not to save our billion dollar profits (I

Health insurance costs rose by 131% from 1999-2009[1], which comes out to just
under 9% inflation. That's in comparison to an average 2.5% inflation for all
goods including healthcare since 2000[2]. 2.5% inflation turns $100 into
$128.01 over 10 years. Instead, we got 231.

they charge. It's not as if businesses will accept year after year double
digit increases without shopping around. If there were big money to be made
undercutting existing insurers, someone would go after that market, but there
isn't: Health insurance profit margins are low single digits at best.

It disappoints me to read the knee-jerk reactions here by those who obviously
have not gone through childbirth. To help some of you along, a "distressed

were under life-threatening duress either during childbirth or prior. This is
not that unusual - things like umbilical cords wrapped around a neck, a small
birth canal, and other reasons can cause significant problems during
childbirth. How many millions of women and babies have died during childbirth?
Half of the commenters here are acting as though childbirth is always a safe
process.

I should point out however, that this 401K match at the end of year practice
is already a standard at IBM, which is probably the worst place to work at in
the Silicon Valley today.

...plus nowadays IBM only starts matching after a full year of employment.

AOL.

Is this the same AOL that still gets a good chunk of money each year from
people that never cancelled their 56k internet subscription when they got
ADSL?
I think AOL is one large moral-free zone.

Why is it a moral failing for AOL to leave it up to its customers to be
responsible for the decision of what services they do or don't need?
~~~
selmnoo
It's not that they're "leaving it up to its customers to be responsible", it's
strategically employing black patterns to exploit specific mistakes people
make.
Are you 100% on top of your every bill? Do you know everything going in and
going out of your bank account? Have you made any mistakes in looking over
something? My friend's dad is a CFO of a Fortune 500 company (and is a
generally well-reputed guy) - I recently found out that he's pretty bad at
managing his home finances - forgets to pay credit bills and all that.
This shit just happens. I'd rather that I deal with a company that doesn't try
to actively exploit me on my weaknesses. The companies that do this have a bad
character and I wish they just didn't exist.
~~~
gdulli
> Are you 100% on top of your every bill?
If I wasn't, I sure wouldn't blame anyone but myself for it. I wouldn't blame
the company I willingly gave money to due to my own oversight. And I wouldn't
be surprised if they didn't call me and ask me to stop paying them.

From my view, this is a case where random big box mgt consulting firm

definitely in the deck.

~~~
FireBeyond
Tell that to the very vast majority of Americans who work their entire lives
without "employer matching" on their 401k's...
Or a smaller but not insignificant number for whom a 401k at all is something
dreamt of.
~~~
ceautery
OK. Dear vast majority....
Actually I'm in that boat, too, but of my own doing. At where I work (a large
utility in the midwest), we match 75 cents on the dollar up to 6%, so
essentially 4.5%. I stopped contributing a few years back to try to get out of
debt faster, but kept finding creative ways to add new expenses: wife, new
daughter, another new daughter, repair that leaky roof, etc.
Still, my point was obvious: 3% is free money that shouldn't be turned down if
it's available, but to laud it as something to brag on is really grasping at
straws. 6% was the industry standard in my area... and I once worked for a
company AOL bought out.

======
natch
I guess because it's an encyclopedia article, and not super on-topic for HN
which is mostly focused on news around startups and technical stuff. If we
submitted every encyclopedia article to HN there would be quite a flood of off
topic stuff.
But mostly because it's 'meh' and off topic enough that not enough people
cared to click the vouch button when it was active. And it's not news.
You can perhaps point to HN links to other off topic articles that have not
been flagged, even encyclopedia articles maybe, but you have to consider that
this topic is quite an outlier and sensitive/private for some people, and not
something they want the discussion to turn into on HN.
So (recapping a bit) they flag, and nobody cares strongly about taking HN off
track into this topic, so the flag remains.

Doing some testing of my own using BDFProxy opened my eyes as to what large

Here's another good reason to encrypt everything. With letsencrypt.org coming
online soon, maybe browsers can start providing warnings to users that try to
download files from regular HTTP connections; though that wouldn't prevent
this problem if the originating website itself is nefarious.
~~~
JoshTriplett
It'll take a while, but this does remove the last excuse sites might have for
not encrypting _everything_.
I'm hopeful that in the next decade any use of unencrypted HTTP will become
suspect, such that browsers can start showing unencrypted HTTP as explicitly
insecure, rather than just as the absence of signs of security. But it'll take
many years to get to that point.

robbiet480
Yet another terrible assassination piece by Johnny Diggz, the CEO of Tropo, a
quickly failing Twilio competitor. He has been a real dick since the early
days and spreads lies and rumors about Twilio.
~~~
josh2600
They're not all lies per se. Tropo/Voxeo also isn't failing :/, they just won
Deutsche Telekom's Euro business.
Voxeo doesn't always have the best marketing team, but they do have a lot of
technical expertise. Their CTO Jose is one of the funniest people I've ever
seen on a panel and he's a delight to converse with.
I don't think any of the metaphors at play here hit the nail on the head.
Voxeo is a large, lumbering enterprise fighting its way into the Carrier world
by virtue of erosion. Twilio is the nimble web-focused startup burning the
candle at both ends trying to fight the night away.
It's not yet clear which strategy will prevail, but I don't think the
mudslinging is the right course either.
Disclaimer: I'm the community manager at 2600hz, which is innovating on the
application switching layer of voice communications. We're also full open-
source.
~~~
robbiet480
I say "Tropo is failing" and I mean that their adoption rate is much lower
then Twilio is. I'm sure Voxeo has tons of money to throw at Tropo until they
run out.
I haven't heard of 2600hz before, great name. I'll check it out!
~~~
mpermar
I am curious here. Is there any place to check Twilio or Tropo adoption rate?
I'd love to get some numbers.
~~~
josh2600
Twilio has like ~150,000 devs in ~4 years, Tropo has like ~300,000 devs in ~16
years. Those are the numbers I hear thrown out, but I'd love to get some
harder details.
------
josh2600
Hello,
So I have a slightly different take on this. (Disclaimer: I'm the community
manager for 2600hz).
I've always thought Twilio was trying to get acquired (their deals with AT&T
and Microsoft seemed to imply a conversation was happening in this regard at
the very least) but for a valuation north of $1B. My personal feeling is that
you can't get a $1B valuation without Mobile and Twilio doesn't really do
mobile in the same way 2600hz doesn't really do mobile (at least not yet).
The walled Garden that is Carrier-land prevents native dialing (dialing
through the handset dialer instead of a native app/web app/plugin). Becoming
an MVNO is super risky, but I was really encouraged by Twilio's announcement
with AT&T and even more so by Voxeo's announcement with Deutsche.
This is a big world and the clear winner of the voice API war will be crowned
in the mid 20-teen's not now. If your argument is that Twilio will burn out
before their acquired, my reply is: Maybe. That's the risk they took, and it's
similar to the risk Square took (see this leaked chart:
<http://i.imgur.com/b1Sm9.png>).
I admire Twilio because they're the best developer evangelism team I've ever
seen. Yes they spend a ton on marketing and they might be the Groupon of Voice
APIs, but the fact is that they're doing it, and if they get acquired all of
the Voice API companies will benefit from their success.
In short, Twilio doing well actually benefits Voxeo and so I don't understand
the worst girlfriend analogy. I'm by no means in love with Twilio, but you
have to admire them for what they do: they're hands-down the best evangelists
for any platform out there. Their developer engagement is nothing short of
awesome.
Cheers,
Joshua

That's what I get for assuming blogs are correct. Thank you for posting the
original article, I'll edit my post above to reflect this.
Thanks!!
Oops, too late to edit, guess my mistake has to rest in stone :/.
~~~
ryanwaggoner
No problem, I only found the original because I was googling around trying to
find some interesting commentary on the "leak". In particular, why do
transaction costs grow so much faster than revenue? That almost implies that
they're going to be processing many more transactions at lower average cost
per transaction, so they'll end up paying a higher percentage of the total in
fees?
~~~
josh2600
My theory is that the additional distribution from their deals with Visa and
Starbucks didn't come with the same business terms they're able to negotiate
independently.
One small biz negotiating with Square versus the gigantic morass that is Visa.
Chances are Visa will have a more dominant negotiating position.
------
pla3rhat3r
Still waiting to find the connection in the article about how Twilio is like
the worst girlfriend you've ever had. Just seems like a jaded bias article
from a competitor. :-/
~~~
tehwebguy
Even if you take out the competitor factor the article was really about their
opinion on Twilio's status as a company.
I expected an article talking about supposedly bad cancelation or privacy
policies, something like that. Pretty bad headline.
~~~
pla3rhat3r
I see he changed the headline. Pretty funny. Not sure how this person has any
insight on Twilio financials. It'd be interesting to get this person's own
background posted on this space. I think it would pull back the veil of
ignorance displayed in his blog post.
~~~
josh2600
I don't think anyone would try to argue that Twilio is profitable. They spend
a lot of money and while they're going to move 500M minutes this year, those
minutes are not free.
The author makes several valid points but undermines the overall critical
nature with what appear to be non-sequiturs. If this article was a frank
accounting of Twilio's position with some postulative math about their
sustainability, I don't think anyone would've objected. The issue was the
accusations, most of the content is factually correct (Twilio did raise a lot
of money and continues to spend a lot of money).
What we have are two different world views, and it's not clear yet who is
correct.
~~~
pla3rhat3r
Don't get me wrong I think every company has it's issues. Some of the
companies you would think are the most stable are some of the most chaotic.
However, there aren't too many instances where an article is taken seriously
when it's written by a competitor. The fact that Johnny is writing this
article while still working at a competitor means this article is meaningless.
It holds no water. It comes off as someone who just wants to slam his
competitor. If he wants to legitimize this article, talk about the challenges
they face. Talk about the problems they've had in the past. Without it, it's a
puff piece. He might as well have published this in the Sun.

"Twiliots" Really?
Voxeo Prophecy is really nice (except for configuration which can be a bit of
a quagmire) and their service is good but Twilio is very, very easy to use.
This piece reminds me that I need to look at Twilio for more than SMS.
------
ChuckMcM
Interesting (if painful) space. I've played with the Twilio API and for what
we wanted (SMS to any phone, ability to dial/talk to a phone and take a
response) it seems to be fine.
That my 'phone' service doesn't offer this as part of the package is what I
find actually broken. For years and years the answer the question "How can I
use my phone?" was "Pick it up, dial, talk." which was fine when it was a
person to person communication device. But when it become a 'computer to
person' communication device it needed a computer friendly API. Had the phone
companies provided that, folks like Voxeo and Twilio and eFax wouldn't exist.

I friggin hate Twilio, and I kick myself for ever getting suckered into using
it. I'm down to a single account and a single line in, but I need to port it
off, and Google doesn't care to port Twilio numbers off to GV. If Twilio could
do something other than drop calls to PSTN (I mean here, make a fuggin VoIP
call), I'd be singing a totally different song, but it's a one-trick pony.

You hate Twilio because you tried to use it for something that it isn't? I

josephlord
I'm looking at Twillio for a possible future project and this just prompted me
to look at Voxeo which I hadn't heard of. The Voxeo website just doesn't work
for me like the Twilio one does, it lacks an pricing information (that I could
find quickly) and even the developer section is mostly buzzword filled non-
information. The Twilio site gives you pricing information up front and the
developer pages show you the APIs and give some examples so that you can
really see what can be done with it.
This doesn't necessarily mean that Twilio will survive or not have to raise
prices but they make me want to use it more than Voxeo even if it has the same
capabilities.
I really do hate sites that hide the pricing and documentation or require
registration to get them although maybe A-B testing shows that gives better
results.
~~~
jdupree
Were you looking at voxeo.com or tropo.com? tropo.com is the site for the
developer API similar to Twilio, and has a documentation and pricing page
linked right on the front page.

That looks much more like it! Will look further.

The gist of the post is that Twilio is losing money, losing talent, and
getting desperate. I don't see why the author couldn't have just said that
instead of picking a sexist blog post title -- he didn't even use the

Edit: They've changed the title. Cool!

I really want to like twilio but it's MADNESS that you can't terminate calls
over the internet. So you're saying EVERYONE in the company has to have skype
numbers just so we can terminate calls?! I would love it if twilio client
actually worked but the sound quality makes it worthless. Hopefully WebRTC
will fix that but who knows how many more years that will be. Please please,
just bite the bullet and build a desktop app that has decent sound quality,
supports multiple accounts and can punch through firewalls. It's stunning to
me that Google Voice, Skype, and Twilio are so poor at serving business
customers.

If you haven't tried Twilio Client in a while I would encourage you to try
again - the call quality has improved dramatically over the past nine months.

swohns
While I don't 100% agree with the piece, our team just stopped using Twilio
and is migrating over to MoGreet beacuse of their MMS capabilities. We already
miss Twilio's strong community, but MoGreet has been incredibly responsive and
supportive.
~~~
josh2600
Seen them before. What made you go with them? Their lack of disclosed pricing
threw me off... I couldn't seem to find any info on their cost structures.

swohns
They are a much smaller operation, which means you'll get the personal touch.
On the minus side the API is less robust and there is little to no
documentation when you need it, I'd give it a stab if I were you, they made it
very easy to migrate over!

Gesture-based movement would be very interesting. Using the app also got me to
thinking about common interactions using links - i.e. click a monster's name
to attack it, an item's name to pick it up, etc. That could take some doing,
though - how could the client distinguish between an object vs. mob, for
example.
Might be interesting to be able to hide room descriptions and tap to expand
them somehow. I don't typically use them in-game anyways, and on the app it's
even more in the way.

In my previous work at a company that made it's money from a browser

I should note it looks like this issue is mostly fixed going forward. The
chrome extension model won, and Firefox and Windows Edge are supposed to be
supporting either directly or through electrolysis.
I.E. was not an extension, but a toolbar, written in C++ (being C++ the
debugger was Windows visual studios so it was doable). Firefox was Xul based
and almost impossible to debug at the time (much improved in recent months),
and chrome just worked.

more "powerful", and Chrome's is a bit limited. But after reading the
experiences shown in this thread, it seems that Firefox's model is actually
harder to use in practice. Would this be related to the maxim that "less is
better"?
~~~
einaregilsson
The old Firefox extension model, XUL/XPCOM is definitely a lot more powerful.
You can basically access anything and do anything. On the other hand much of
it is not documented and you're on your own in figuring out how it works. But
they're trying to move people off that model, and onto the Add-on SDK or the
chrome model, which is a lot easier to work with, and better documented.

*two browsers
Opera 15+ is merely a fork of Chrome with some slight ui modifications. It
does not merit being called a browser in its own right.
~~~
einaregilsson
Should maybe have been 2 and a half browsers. There are some slight
differences, e.g. the way options pages are opened from the extension page,
but basically Opera is just Chrome. What is the point of Opera, I don't really
know why anyone would use it, but it was basically free to make the extension
work for it, so I decided to include it.
~~~
Mithaldu
> What is the point of Opera
Opera up to version 12 was a great standalone browser with UI and performance
characteristics still surpassing all competitors even at this point in time.
(As long as you exclude JS-heavy things.)
However at some point MBAs managed to take over, decided to continue making
most of the company income with their mobile ad network.
Developing Opera 12 further was expensive, so they figured out a way to keep
most of the users (for the ad revenue), while radically slashing the dev
expenditure on the browser: Fork and rebrand chrome, while adding a few token
features, pretend Opera 12 doesn't exist, and push people heavily to
"upgrade".

martin-adams
I wrote my first extension for a proof of concept project for Chrome last
month, and I literally had my first working example doing something
interesting within 2 minutes.
I tried to do the same in FireFox, and gave up. I couldn't get my head around
the documentation without taking a day out to get going.
~~~
einaregilsson
Firefox is also starting its third extension model now. At first it was
XUL/XPCOM where extensions could basically hook into ANYTHING in the browser,
then there was the Add-on SDK (formerly Jetpack), which is kind of nice, but a
lot more limited, and now they're going with WebExtensions, because, well,
Firefox basically does nothing but copy Chrome anymore ;)
But yes, that does make it complicated to figure out what's the best way to
make stuff for Firefox.
~~~
evilpie
>Firefox basically does nothing but copy Chrome anymore ;)
Thanks
If you can wait for the WebExtension API. If not use Jetpack. Don't write new
extensions with XUL/XPCOM.
~~~
einaregilsson
Sorry, that was unnecessarily snarky. But it does seem like Chrome is leading
and Firefox is following on a lot of things. The look, multiprocess, extension
model, all things that started in Chrome.
I was pleasantly surprised by Jetpack though, the jpm tool is very nice.
~~~
vinay427
As a primarily Firefox user on Linux I do agree with you about Firefox mostly
following Chromium these days. It seemed like for a long time Chromium was
adding in features Firefox had with improved implementations, but now Firefox
appears to be lagging. The Firefox extension model did allow for extensions
like DownThemAll which I don't think can survive in this generation of
extension models.
~~~
icebraining
Yes; I have no problem with adding an API to make simple things easy, but
TreeStyleTabs, VIMperator, Firebug, all of them need something more powerful
than the Chrome model. I really hope they don't deprecate the old model and
leave power users out in the cold.
And frankly, the old model is not so bad; if you're building any kind of
extension that does more than connecting a button to an HTTP call, the couple
of hours you'll need to get started are irrelevant in the long run.
------
tonetheman
I have written browser extensions in Chrome very successfully. And failed
horribly with Firefox.
Now when I see any working extension in Firefox I marvel at how much work that
person must have put in to get it to work. Over time hopefully Firefox will
get better. But the extensions have been bad for a while...
~~~
icebraining
I've built a Firefox extension (now abandoned), which even used XPCOM, and
while the documentation was spotty (this was back in 2010, it may have
improved), it wasn't particularly difficult. The fact that you can easily
unzip any extension and look at its source makes up for a lot of gaps in the
docs.
------
kitsunesoba
It’s not mentioned in the article (understandably), but writing an extension
for desktop Safari is very similar to writing an extension for Chrome. One can
even use the same codebase in most cases — the biggest differences are that
Safari is a little more conservative in what it gives extensions access to and
any Chrome-specific JS obviously won't work.
~~~
einaregilsson
But you need a Apple developer license to develop for Safari, and that costs
99$ per year :/

The FroYo update: a list of phones confirmed for Android 2.2 - Thracks

======
aditya
It is open source software - right? Why aren't there any homegrown releases
for these updates that bring them to your phone before your carrier does? Or,
am I missing something?
~~~
Thracks
IIRC, Google has released the Android 2.2 kernels to their open source
project, but it will take time for homebrewers to polish them up for
tomorrow's unsupported handsets.
Every major Android phone is likely to get the update, but it'll take time and
betas.
//EDIT: In many cases, the homebrew community DOES provide ROMs before the
carrier. The Samsung Moment, HTC Hero and HTC Droid Eris were all given
Android 2.1 by the community before their respective carriers pulled the
trigger.
------
ZeroGravitas
Seems odd to conclude that slower phones won't get an update, when the key
feature of the update is faster speed. I'm not saying his conclusion (that
only a subset of phones will get official update support to 2.2) is
necessarily wrong. It just lacks internal logic.

ReactOS 0.4.0 Released - ekianjo
https://reactos.org/project-news/reactos-040-released
======
mhd
I'm quite impressed that they can load graphics drivers now. Those generally
seem to be arcane as heck, delving deeply into the internals of not just the
applications they support (e.g. games), but the operating system itself.
Although I guess this is a more basic level, i.e. not using Nvidia drivers to
run 3DMark...
~~~
adam12
I've got a bunch of old games that I can no longer run on Windows 8/10\. If
they can get some of those running smoothly, ReactOS will see a surge in new
users.
~~~
TazeTSchnitzel
With its NTVDM, ReactOS can actually play DOS games out-of-the-box, which is
something modern (64-bit) Windows releases can't do.
~~~
speeder
As a hardcore gamer, gamedev and old games lover, I am finding sadder and
sadder that certain games are getting increasingly forgotten by everyone, and
noone even remember they are in dire need of tools to make them work.
It is the games from Windows 98 and XP era, many used some combination of GDI
and DDraw that doesn't work at all on new Windows versions, DDraw emulation is
mostly broken, and pity you if the game used DDrawEx (it was to mix DDraw with
D3D).
For example I am currently trying to figure a way to play SimCity 4 properly,
the game is too demanding to run in an emulator, so some kind of native
implementation is needed, but it also uses DDrawEx, that is very poorly
supported in all OSes except Windows 98, ME and XP (it doesn't work in XP
contemporary NTs either).
I think this is the kind of games the OP is happy ReactOS maybe will
implement... because for DOS games, DosBox is more than enough already in most
cases (there are some exceptions, like Noctis that is incredibly CPU-intensive
and runs at 3 FPS in DosBox).
~~~
TazeTSchnitzel
You could try running Windows 98 under VirtualBox.
~~~
sspiff
Those old operating systems are quite a pain in VirtualBox. Qemu does a much
better job, in this case. VirtualBox's emulated hardware is too new for some
systems, and Win98/Win95 flood the CPU during idle time (because that's how
things worked back then), causing the input processing from the VM to lag
significantly.
Regardless though, this would legally require you to acquire a licensed copy
of Windows 98, which will only become harder and harder down the road. Unless
Microsoft decides to "free" all legacy software at some point.
ReactOS and WINE solve this problem in a different way, by providing open
source solutions that everyone can use, copy and archive without cost or
consequence.

They're using kinetic/smooth scrolling, which is included in theme they're
using from Okler. If you look in the JS, you'll see:
Plugin Name: smoothScroll for jQuery.
Written by: Okler Themes - (http://www.okler.net)
And here's a forum where a customer asks to disable it:

Another offender:
[https://www.astralgameservers.com/](https://www.astralgameservers.com/)
Inertial/kinetic scrolling is _incredibly_ frustrating when implemented in JS.
On my Mac, sure, if I swipe my fingers and let go, I expect the OS to emulate
a free-spinning scroll wheel. But when it's emulated in JS, there's no way for
the code to know whether I lifted my fingers, so it defaults to making the
page skid around uncontrollably, when I intend to quickly swipe - while
keeping my fingers down at the end - to go to a precise offset in the page.
It's visually a cute a effect, but I have no idea how anyone thinks that it
makes for anything other than an utterly infuriating user experience.

i ask out of curiosity not criticism. it seems like a cool project so I'm
wondering it's benefits over existing OSes.

It's free, it's open-source, it's Windows-like, and it can run Windows
applications. It's very lightweight and has a live CD.

alkonaut
Those are all good of course, but how long before it is _significantly_ better
(faster, more compatible, easier) than e.g. doing the same with Wine? is it
already?
~~~
cookiecaper
It doesn't do the same thing. ReactOS is a full reimplementation, including
the Windows kernel. You can boot your system with it. One of the main goals is
to provide for the loading of Windows drivers. ReactOS and WINE share code for
userspace to the extent possible.
~~~
alkonaut
I see. Is the reason it wants to use Windows drivers that it hopes to get
better performance in comparison to Wine or VMs?
~~~
userulluipeste
The hardware vendors used to pour more effort into the Windows drivers than
into the other ones. (I think it's not about being unfair or against FSF
ideology, it was just that the market so far was still heavily in the Windows'
courtyard, so they were kind of forced to give in and have the other platforms
only on lower priority.)
------
pippy
I've often thought there's a massive market for ReactOS in legacy support.
There's so many platforms (ATMs, flight controllers, banking software) that
use unsupported windows versions. Many of these platforms would pay an arm and
a leg for ongoing support and security updates.
~~~
chris_wot
Actually, I'm curious, but for slightly different reasons. Windows can _still_
technically support other architectures than x86; if ReactOS is truly
compatible (which it evidently is!) then I wonder how hard it would be for
them to port the HAL layer to things like SPARC.
~~~
slipstream-
uh, Windows does support other architectures than x86: currently, it supports
x86, x64, ARM and ARM64. (and as Windows Server 2008 R2 is still supported,
the IA64 version is also still suppored)
~~~
chris_wot
Yeah, I know. But it will never support SPARC. Or anything other than the
architectures you mention. Windows can still support these other
architectures, I'd love to see it happen. ReactOS might be the way that it's
made to occur.
~~~
chungy
Definitely. Microsoft doesn't see commercial value in supporting, eg, a SPARC
version, especially when it won't run existing x86 apps. It'd be a huge lost
cost in development just to make one.
ReactOS isn't driven by the same market forces. Anybody with enough
determination can port it to SPARC and fly away :)
Windows NT 4 supported x86, MIPS, PowerPC, and Alpha. All but one were dropped
with Windows 2000... and it wasn't until XP that non-x86 returned (initially
IA-64, and x86_64 in three more years after initial release).
------

The project is neat, but they should not be proud of "9,000,000+ lines of code

donlzx
Kudos to the ReactOS team. I've tried the 0.3.x release about ten years ago
and was a little disappointed. However, after a decade I've got a new
perspective to appreciate their work.
I've kept several of my used laptops (Toshiba Satellite laptop, IBM Thinkpads,
Lenovo Thinkpads, etc.) mainly for commemorative purpose. However, they can
still boot and works fine with outdated OS's and extinct software. A potential
very good use of them is to open my old archived documents, but I'd rather not
to mess with these fragile machines.
When I checked my old archives, usually only plain texts and JPEG photos files
are fine with current OS's and softwares. Nealy all my old software projects
(mostly with Visual C++) no longer compile or run, or missing dependencies
(DLLs, component libraries, tools, etc.). Even though I've backup most of the
tools I used at that time, most of them would be a huge pain or impossible to
reinstall correctly with right system dependencies.
Therefore I've come to think that the only meaningful archives are data with
executables, i.e, documents with related spec, contemporary software and OS.
In this aspect, a good Internet archive methodology should be like this: 1)
data; 2) Fully installed and working software packages; 3) Running free OS
such as Linux and ReactOS; 4) OS emulator on available hardware such as
Virtualbox and KVM.
The importance of ReactOS here is that we will have a working OS on modern
emulator or hardware for archiving purpose.
I'm omitting the hardware platform here, but it should be the other important
aspect of archiving our knowledges.

cool drop-in replacement for any server apps that people decide to target to
Nano Server.

On IRC the developers have mentioned (as wishful thinking) a minimal (i.e. a
stripped-down) version, with only kernel, drivers, and a few other small
miscellaneous parts over which dedicated applications could run. This would be
something for embedded systems and other specialized machines (basically
servers) unlike the all-encomprising common version of ReactOS. That having
been said, it's important to understand that one of the reasons for nano is...
well, OS size, which for a "normal" version got to tens of GBytes! Currently,
ReactOS is (and I think that's a lot --) under 200 MB with all its bells and
whistles.

Kubernetes 1.10 released - el_duderino

wolfgang42
Is there an easy way to get a single-node production-ready Kubernetes
instance? I'd like to start using the Auto DevOps features that GitLab is
adding, but all the tutorials I can find either have you installing minikube
on your laptop or setting up a high-availability cluster with at least 3
hosts. Right now I'm using CoreOS and managing Docker containers with systemd
and shell scripts, which works all right but is tedious and kind of hard to
keep track of. I don't have anything that needs to autoscale or fail over or
do high availability, I just want something that integrates nicely and makes
it easy to deploy containers.
EDIT: I should have clarified, I want to self-host this on our internal VMWare
cluster, rather than run it on GKE.

I'm very curious to hear field reports from people who switched to using
Kubernetes in production in the last year or so. Why'd you do it? What got
better and what got worse? And are you happy with the change?
~~~
linsomniac
One data point: I've wanted to but so far have not made much progress. I'd say
my biggest impediment has been documentation: I can get it installed, but
making it work seems to be beyond the scope of the documentation. I got
closest once I found out about "kubespray" to install the cluster rather than
using the official Kubernetes installation docs process.
I spent a couple weeks not quite full time going through tutorials, reading
the documentation, reading blog posts and searching for solutions to the
problems I was having. My biggest problem was with exposing the services "to
the outside world". I got a cluster up quickly and could deploy example
services to it, but unless I SSH port forwarded to the cluster members I
couldn't access the services. I spent a lot of time trying to get various
ingress configurations working but really couldn't find anything beyond an
introductory level documentation to the various options.
Kubespray and one blog post I stumbled across got me most of the way there,
but at that point I had well run out of time for the proof of concept and had
to get back to other work.
My impression was that Kubernetes is targeted to the large enterprise where
you're going to go all in with containers and can dedicate a month or two to
coming up to speed. Many of the discussions I saw talked about or gave the
impression of dozens of nodes and months of setup.
Other options I'll probably look at when I have time to look at it again: Deis

andrewstuart2
Are you trying to play around, or set up a working cluster? If you just want
to play around, I'd suggest just using minikube to get things going.
Anecdotally, I got an HA cluster running across 3 boxes in the space of about
a month, with maybe 2-3 hours a day spent on it. The key for me was iterating,
and probably that I have good experience with infrastructure in general. I
started out with a single, insecure machine, added workers, then upgraded the
workers to masters in an HA configuration.
I don't think it is really that hard to get a cluster going if you have some
infrastructure and networking experience, especially if you start with low
expectations and just tackle one thing at a time incrementally.

Full Disclosure: I work for Red Hat in the Container and PaaS Practice in
Consulting.
At Red Hat, we define an HA OpenShift/Kubernetes cluster as 3x3xN (3 masters,
3 infra nodes, 3 or more app nodes) [0] which means the API, etcd, the hosted
local Container Registry, the Routers, and the App Nodes all provide (N-1)/2
fault tolerance.
Not to brag, since we're well practiced at this, but I can get a 3x3x3 cluster
in a few hours, I've lead customer to a basic 3x3x3 install (no hands on
keyboard) in less than 2 days, and our consultants are able to install a
cluster in 3-5 working days about 90% of the time, even with impediments like
corporate proxies, wonky DNS or AD/LDAP, not so Enterprise Load Balancers, and
disconnected installs. Making a cluster read for production is about right-
sizing and doing good testing.

To follow this up, can anyone explain the benefits over Docker? I've used
Docker before but am unfamiliar with Kubernetes terminology. I do understand
it's an open source project by Google.
~~~
p3llin0r3
Kubernetes USES docker, so it's not a competitor.
The main benefits over the competing docker project, Docker Swarm, is that it
does WAY MORE, is 100% free and open source, and has much better adoption.
I would argue that with Docker Swarm you have to bring the glue yourself, and
it doesn't really solve any of the hard problems. Kubernets on the other hand
is an all-in-one package that solves a LOT of hard problems for you.

Kops has not released a 1.9 version yet. Even k8s projects can't keep up.
~~~
AlexB138
Kops generally stays one release behind. 1.9 is being end to end tested in the
last week. I wouldn't use that as an example of not keeping up, it's the
established cycle for the project.
~~~
justinsb
kops 1.9 is very close to ready now, but this is a longer lag than normal.
We've historically released kops 1.x when we consider that k8s 1.x is stable,
including all the networking providers and ecosystem components. That's
typically about a month after release.
User feedback has been that that we want to keep that, but that we should also
offer an alpha/beta of 1.10 much sooner, so that users that want to try out
1.10 today can do so (and so we get feedback earlier). So watch for kops 1.10
alpha very soon, and 1.11 alpha much earlier in the 1.11 cycle.

I see some people who use Elixir/Erlang ecosystems then shove them into a
kubernetes system. Isn't this going against what the Elixir/Erlang system
already provides ? What are the usecases for this?
~~~
troutwine
> Isn't this going against what the Elixir/Erlang system already provides?
No?
So, I guess, let's dig into that a little bit. Erlang's always kind of left
the health and safety of your deployed system as a whole up to you, being
preoccupied with giving you tools for understanding and maintaining its
internal operation. OTP provides two semi-unique things: supervision of
computation with control of failure bubble-up and hot code reloading. Hot code
reloading isn't used all that much in practice, outside of domains where it's
_very important_ that the whole system can never be offline and load balancing
techniques are not applicable. That's a specific niche and, sure, probably one
that kubernetes can't service. With regard to supervision, there's no
incompatibility between OTP's approach and a deployment consisting of of
ephemeral nodes that live and then die by some external mechanism. Seems to me
that kubernetes is no different a deployment target in this regard than is
terraform/packer, hot-swapped servers in a rack or any of the other deploy
methods I've seen in my career.

For the folks who have implemented K8 in Production - curious if you use it to
do resource management as well, or, if you also use something like Mesosphere
in conjunction? Or would you stick with a like-stack (DCOS+Marathon)?

of Resource Management and Container orchestration. Not sure if it is too
early in the curve, a dark art, not actually done, or what...

Kubernetes does resource management; all cluster scheduler systems do. The
difference between Kubernetes and Mesos for resource management is that
resource requests and limits are optional in Kubernetes and mandatory in
Mesos. It is best practice to specify resources in Kubernetes.

I've run vanilla k8s for about 3 years now in prod but am also fairly familiar
(and really like) Openshift Origin. I usually tell people asking this question
the following;
OO comes with a bunch of really nice quality of life improvements that are
missing (but in a lot of cases can be added via 3rd party TPR/CRDs/etc) in k8s
but you aren't deviating so far from k8s that you won't be able to go work on
vanilla k8s in the future. Not at all. Most of the additional stuff are
annotations that simply wouldn't do anything and you'd remove them if you
moved from OO to k8s.
I think that if you're brand new to the environment OO can really help you get
running quickly. You just have to make sure that you do in fact dive in to the
actual k8s yaml and deal with ingresses, prometheus, grafana, RBAC, etc at
some point. I haven't used OO in awhile but I believe you could successfully
do most of what I do day to day via yaml/json through the OO UI.
On the flip side a lot of people will probably tell you to start from k8s,
whether that's GKE or AWS or minikube or wherever and go through the k8s the
hard way. Personally, and I help people quite frequently on the k8s slack, I
feel like that leads a lot of people down a path of frustration. It may be
perfect for your style of learning or it may just scare you off.
Now when it comes to OO you are at the behest of their releases. Their most
recent release was Nov 2017 and k8s 1.10 was just cut. I'm not sure what
version OO is on now, evidently they changed their versioning numbers to not
correspond to the k8s version.
Join #kubernetes-users and #kubernetes-novice on slack.k8s.io if you need any
help. It's a vibrant community. You can message me directly @ mikej if you'd
like.
edit: Ok OO 3.7 is k8s 1.9, that's perfect. I wait a few months before jumping
into new major.

No moderator touched your post. It fell in rank because users flagged it.
It's against the HN guidelines to turn questions like this into Ask HN
threads. Please don't do that. As the guidelines say, you should email
[email protected] instead.
Also: when a post is flagged, a repost counts as a duplicate. Otherwise flags
wouldn't mean anything.
~~~

Define flagging. I've been a member of HN for almost 5 years with low to
medium activity and all I get is upvote/downvote capabilities. As far as I can
see, there were minimal downvotes from me watching (or at least equivalent to
upvotes), so the flagging seemed to be a group effort near instantaneously.
Things immediately went from good to bad in the matter of seconds, so there's
alot of power in whatever ranking is required to "flag".

My guess is an upvote collusion algorithm got tripped somehow. The post is
obviously being penalized for some reason.
~~~
jqueryin
To the point on upvote collusion, I think the mods really need to rethink
things a bit. I utilize HN on a daily basis and check it periodically
throughout the day. If I see a post of a friend's site, I upvote it. The
notion of being flagged because friends or acquaintances familiar with your
startup being happy for you is by no means a reason to degrade a post.
What the OPs are really saying is they'll let it slide for their friends and
network, but not for those they're unfamiliar with. This is outright
unacceptable behavior and I think methods of accountability should be added.
If a startup didn't have friends, fans, and followers, than what do they have
guys? Nothing. And I'll be damned if I don't work for an awesome startup doing
awesome things that earned it's spot on the front page. It's a shame.

OP? Usually, when I've seen that in a forum, it means "Original Poster", the
submitter of the post to which the comment thread is attached -- but clearly
that's not what you mean here. Do you mean the mods?
And, no, the voting ring detector is, from everything that has been said about
it, algorithmic, so its just as wrong for anyones "friends and network" as for
anyone else's.
> This is outright unacceptable behavior and I think methods of accountability

I'm sure if you ask nicely, YC will refund 100% of the HN membership fee you
paid if you are unsatisfied.
> If a startup didn't have friends, fans, and followers, than what do they
> have guys?
The idea of HN is that things should be promoted in visibility based on the
interest to the community at large based on the content, not based on
collusion of groups to promote them. Hence the voting ring detector. There's
plenty of venues for promotion that don't work that way, but I don't see why
anyone (other than YC) is entitled to demand that HN change.

Correct on mods, I was ranting too fast. I'll maintain my rights to rant on

I guess we'll wait and see.

Time-based exponential decay is the norm. Per the FAQ [1]:
_How are stories ranked?_
_On the front page, by points divided by a power of the time since they were
submitted._
Also, from the guidelines [2]:
_Please don 't post on HN to ask or tell us something (e.g. to ask us
questions about Y Combinator, or to ask or complain about moderation). If you
want to say something to us, please send it to [email protected]._

By my manual count, 6 of the 16 comments in the discussion are by you and you
are also the person who submitted the piece. I have tried to tell others this
and people think I am being a bitch when I do so, but commenting too much in
your own submission seems to not be a good idea.
I wrote about my own experience/observations here:
[http://micheleincalifornia.blogspot.com/2014/03/so-you-

yourself between one and three GOOD comments, then stfu and let _other people_
talk about your thingamajig.

You know, I am female and I used to really be given hell at times on HN. It
took me a long time to understand why that was (most of which is not relevant
to this discussion) but I don't think it helps you at all to talk about "this
crowd is getting as rough as..." etc type stuff. If I had just been looking to
blame people here, I imagine I would have ended up banned. Instead, I took
some time off, figured some things out, and was eventually able to return to a
much more successful experience. As far as I can tell, that means I am
currently the highest ranking (in terms of karma) actively participating
female member. And this is a forum that is fairly notoriously unwelcoming of
women. So I think I speak from both a place of success and the school of hard
knocks on this one.
From what I can tell, there is some sort of algorithm that drops you off the
front page if you comment too much in your own submissions. Most likely, the
mods have good reasons for that. If you want to do well here, it helps to
understand the technical environment as well as the social environment. If you
don't want to understand it as a path to improving your performance, if,
instead, you just want to blame someone and complain, well, it's been nice
knowing you. You won't get far here. That kind of thing does not play well
anywhere and it seems to play especially poorly here.

Why No One Is Beating Tesla's Range - prostoalex
https://jalopnik.com/why-no-one-is-beating-teslas-range-1837952903
======
kenhwang
No one's beating Tesla's range because no one is willing to use the NCA
battery chemistry. All the other automakers stick to NMC (for very good
reason). Tesla will have a ~20% range and cost advantage just by nature of
using NCA over NMC.
~~~
mikeash
That doesn’t seem to explain why other cars are getting less range from
batteries with similar capacity.
~~~
kenhwang
NMC batteries needs to be much bigger/heavier to match the capacity of NCA due
to NCA's better energy density. Then you have both the increased weight and
increased cooling burden associated with the larger NMC battery that
negatively impact range.
~~~
mikeash
That doesn’t add up. The I-PACE and Taycan both have similar weight to the
Model X, yet are substantially less efficient. The e-tron is lighter than a
Model S and has absolutely horrible efficiency.
~~~
kenhwang
The e-tron is similar in weight, size, and power to the Model X and pretty
much gets within 10% of its efficiency comparing WLTP ratings. I think the
efficiency loss can be explained by cooling (if this article is to be believed
that Audi has more complicated/expensive cooling) and aerodynamics (it has a
normal SUV profile vs the coupe of the Model X).
~~~
mikeash
I found about 250 miles for the e-Tron and 315 miles for the Model X competing
WLTP ratings. I imagine aerodynamics are a huge factor in this difference.
~~~
kenhwang
For 83.6kWh usable battery on the e-tron vs 95kWh on the Model X.
~~~
mikeash
Ah, I just saw 95kWh and figured it was close. I didn't realize the usable was
so different.
I'm a bit suspicious of the WLTP ratings for these cars. The EPA rating for
the Model X Long Range is 325 miles, while the e-tron's EPA rating is only 204
miles. Any idea why the Model X would score lower on WLTP while the e-tron
would score so much higher?
~~~
kenhwang
They probably just have different blends of city/highway/speeds. Just like how
gasoline cars have different estimates from different testing agencies,
electric cars do too because they all have different efficiency curves.
The ratings generally try to mimic the driving conditions of the region and
automakers tend to optimize for their home turf. So it's not too surprising
the American automaker does better on the American test and the Europeans do
better on the European test.

This is, at best, "sponsored content" from Audi, and at worst, an Audi
advertisement directly written by a PR firm. Why is this on the front page of
HN?
~~~
braythwayt
The first sentence is absolutely true. And frankly, unsurprising to anyone who
has been around the magazine industry for longer than a week or two.
As they used to say of computer magazines in their heyday, “Everything in the
magazine is an advertisement, some of which are labeled as such.”
Paul Graham wrote an essay about PR in this site’s early days called “The
Submarine,” where he credited PR for the success of his own startup that he
sold to Yahoo.
PR is part of the game, and recognizing it as such is part of the game.
BUt with respect to your second sentence, just because it’s PR doesn’t
necessarily mean it is false or misleading. That assumption would be an ad
hominem fallacy.
A PR piece planted in Jalopnik isn’t that much different than an interview
with the CEO. You know the CEO is stating their company’s official position,
but you may still want to hear their point of view.
I 100% agree it is useful to make sure that everyone reading this be aware
that it is mostly ghost-written by VW Group. But once you are aware of that,
it is still useful to read it and debate amongst ourselves whether their
claims are reasonable and informative.
Personally, I thought the article did a good job of explaining that they were
repeating VW’s claims. It did not feel like they were pretending to print the
views of a so-called “independent think tank.️“
JM2C.

Benjammer
I just honestly don't think it's even worth it for us to discuss this article
on a somewhat technical, popular discussion forum like HN. It doesn't make any
attempt to give background/contextual information about any of the specific
issues discussed, it simply jumps right into pushing the Audi features and
openly bashing Tesla with vague generalizations; for example:
"Motor cooling is the weak link in the Tesla Model S, with motor heat soaking
usually responsible for power reductions under hard driving."
It doesn't explain the motivations of either company's designers and
engineers, it doesn't give background science on cooling technologies, and it
doesn't even really explain why Audi's system is better. It just says Audi has
"more aggressive and redundant cooling systems," and that Tesla's cooling, "is
the weak link in the Tesla Model S," with little-to-no further explanation.
If you are talking about an interview with a CEO where they focus on how they
are better than one specific competitor, and come off petty, shallow, and
unreasonably biased, then I would have similar feelings about that content. A
bunch of us here talking about this article is what a marketing analyst's or
PR agent's dreams are made of.
~~~
braythwayt
One of the pleasures of HN for me is that when a shallow article is published,
sometimes a bunch of people chime in and give more thorough explanations, e.g.
the discussion here about the tradeoffs between the battery technologies used
by Tesla versus Audi (and just about everyone else).
If the article serves as an invitation to a good conversation, I’m all for it.
But of course, sometimes an article is so bad that the entire conversation is
composed of people debunking its nonsense.
Or worse, certain highly emotional topics get posted, and everyone just yells
past each other. Regardless of the quality of the OP, the conversation makes
me feel like I lose 50 points of IQ when I read the comments.
I sum, I agree that sometimes, bad articles make for bad conversations. Did
this one? Maybe, maybe not, I’ll accept your word for it if you think poorly
of the quality of conversation around it.

The article still doesn't explain the 166 mile difference in range despite

that Tesla has probably the most data worldwide to train self-driving AI and
way more experience in building fully-electric cars, no one comes remotely
close to what Tesla can do. Modern non-Tesla still are sold with "map updates"
ffs, and something like "remote software update" is totally unheard of.
Tesla's strength is software and extreme agility in software development. The
other car manufacturers are prevented by their sheer size and corporate
infighting culture to catch up and they will be for years to come.

I'd counter argue that it's maybe not that bad to have proven, formally
validated software in the field, which is what traditional software developers
in the automotive sectors did for decades. You tend to push out less crap if
you are forced to make sure it works well from the start due to lack of
updates.
At least the German Automotive industry relies very much on formal
verification and model driven development for this reason.
~~~
solarkraft
Except the UI stuff they push out _is_ utter crap. It's slowly improving, but
I if I understand the industry correctly the efforts that are leading to that
started many years ago.
Meanwhile when Tesla releases a bug they can ship a fix within days.
Why arbitrarily limit your development like that? To make some money off your
customer being forced to go to the dealer to get an update? That's just
terrible UX.

Even using the quoted 83.6 kWh figure as comparison, tesla gets 50% more miles

Good point. Well, I guess we need to wait 7-8 years until the batteries from
other manufacturers become worn and see if their claims stand.
Battery reliability in the long term as well as sustained performance should
not be underestimated.

Some manufacturers are beating Tesla on price and range. The Hyundai Kona can
be bought for a bit less than a similarly priced Model 3 and the Kona has more
range at that price point. The Volkswagen ID.3 will come with three battery
sizes for 330km, 420km, and 550km WLTP range and they will be cheaper than the
equivalent range Model 3s.
~~~
mamon
WLTP range is different measurment that Tesla's EPA range. Conversion rate is
approximately 1.12:1 ([1]), so ID.3 EPA range would be 491 km.

I believe traditional manufacturers probably know more about building cars
that can last (thought not in all cases certainly). But yeah, this does come
off as a bit hype-ish over details that probably matter a lot less to buyers.

Traditional manufacturers also know that they make money from maintaining
cars. If traditional manufacturers make cars that last, they will go out of
business.

ineedasername
There's a balance they have to strike. If you can't on average get 7-10 years
out of a car with normal preventative maintenance, you won't sell many as both
those who buy for the long term and the secondary market for used cars will
avoid.

Microservices without the Servers - alexbilbie

This is Amazon's wet dream. Your app isn't an app at all, it's just a
collection of configs on the AWS Console. When and if the time comes to
migrate off of AWS, you realize you don't actually have an app to migrate.
~~~
arihant
Or, you realize that your processes are so minimalistic and well structured
due to lack of options, that you only have to write a custom request router
over the weekend to migrate.
Also, Lambda-like options are available with most PaaS providers now.
It is not much different and might be easier than migrating web app from a
custom PaaS. The only issue is, and has always been, the migration of data.
And I don't see that getting solved until some startup writes a bunch of
layers on top of a bunch of providers. It's very tricky, for good reasons.
~~~
IanCal
> Also, Lambda-like options are available with most PaaS providers now.
Which other ones are there? I used to use PiCloud until they were bought out
by dropbox and it atrophied. Shame, it was exactly what I wanted in a service.

But you don't have future price information; so it's a bit hard for an actual

recommend it to a client?

Interesting that the article talks about load tests but omits any results.
I was trying out a Gateway API + Lambda + DynamoDB setup in the hope that it
would be a highly scalable data capture solution.
Sadly the marketing doesn't match the reality. The performance both in terms
of reqs/sec and response time were pretty poor.
At 20 reqs/sec - no errors and majority of response times around 300ms
At 45 reqs/sec - 40% of responses took more than 1200ms, min request time was
~350ms
At 50 reqs/sec - v slow response times, lots of SSL handshake timeout errors.
I think requests were throttled by Lambda but I would expect a 429 response as
per the docs rather than SSL errors.
My hope was that Lambda would spin up more functions as demand increased, but
if you read the FAQs carefully it looks as though there are default limits.
You can ask these to be changed but that doesn't make scaling very realtime.
~~~
balls187
Correct. Lambda isn't designed for high data through put. That's what Amazon
Kinesis is for. Each Kinesis shard can handle 1000KB/s data injestion rates.
You would write your data to a kinesis stream, then use Lambda to respond to
the kinesis event to write data to your DynamoDB table.
~~~
paulspringett
Thanks for the info on this, I hadn't seen Kinesis before. I also tried
something similar with S3 upload but Kinesis looks a much better solution for
what I'm trying to do.

raspasov
I see a lot of people disagreeing with the overall direction of "less servers,
more services". I totally get it, I used to be one of those people, but I
think the shift to "less hassle development" is inevitable.
5 years ago people used to debate whether we should use a virtualized server
vs. a physical one. You still can see similar discussions but rarely - we all
have more or less agreed that using AWS/Rackspace/etc. is good for a business
in majority of use cases.
I think 5 years from now we'll still be debating servers vs. services, but the
prevailing wisdom will be that "services" have won.
~~~
alexro
It may well be so that companies will run their private clouds on the
colocated servers. What wins in that case?
~~~
raspasov
Maybe for some companies/use cases, however my feeling is that the setup time
and dealing with hardware directly will always be too much hassle for the
majority.
~~~
alexro
Except they will deal with hardware anyway - there are about several thousand
different devices in our offices. How difficult is it to get another 2 admins
- and two could be enough in the modern world of everything automated.
------
xchaotic
It is pretty cool but not really serverless, you are still handling http
requests via Amazon API gateway and in general you are relying and paying for
quite a lot of Amazon services. Not sure how much better this approach is to
serving image magic via PHP for example, it would be good to see some numbers.
~~~
philsnow
This removes nearly all of "devops". You don't have to mess around with
figuring out how many ec2 instances you need (or deal with auto-scaling
groups), how to secure the linux or whatever you stick on the ec2 instances,
etc.
There's still a ton of creating zip file artifacts of your lambda payloads
(instead of pushing to a magic git repository that amazon controls, say), so
there's a bit of "build monkey"ing to do instead of "devops"ery. But I think a
lot of shops will be happy to make that trade, as "build" is closer to their
core experience than "devops".
~~~
maratd
Yes, you get rid of devops.
You gain vendor lock-in. You are now tied to the Amazon platform. If they shut
down or suspend your account, for any reason, you are out of business. You are
also paying premium for the platform, with the cost of devops built in.
I'll take an open ecosystem that gives me options to migrate my business
anytime over a proprietary solution.
~~~
curiousjorge
pretty much this. amazon can at any point shut down any of these services or
nerf it. if you built everything up to this point on amazon and they shut it
down, it's more work.

Are servers really that hard to manage these days? This seems like way more
work and pretty limited in what it can really do, especially compared to a few
lines of code in any decent web framework that can perform a lot faster.
~~~
herval
If you're a single developer/small team with a very small product, managing
servers is a chore that won't add any value to the product you're building.
So you either spend very little time on it and build servers adhoc
("snowflake" style - SSH in, install some stuff, etc), or you spend precious
time doing "the right thing" \- which right now is a huge universe of options
(Chef/Puppet/Ansible, Docker/other containers/no containers, etc).
If you're part of a larger team, not having a properly structured
infrastructure is a nightmare - specially when it comes to scaling or dealing
with failures of all kinds.
TLDR; - yes, I'd say it's somewhat hard...
~~~
joeyspn
> I'd say it's somewhat hard...
I don't think it's hard, it's just time consuming. And we all know that "time
is money", specially for small teams or solo devs (as you pointed out).
~~~
herval
Doing it right is hard. Scaling infrastructure throughout multiple zones while
keeping data as consistent as possible, deployments as easy as possible and
having as few SPOFs as possible is pretty difficult (and done differently by
every single team). The range of things that can go wrong is huge...
~~~
joeyspn
Not every product needs AZ from the start (specially for small teams or
solopreneurs), in most cases you'll be doing over-engineering. And in the use
cases you need AZs and _do it right_ new tools like convox* are really easy to
use and can save you a lot work. It's never been this easy to manage your own
infrastructure.
During the years I've used ssh, puppet, fabric, ansible, capistrano, cloud
formation, etc for managing servers and infrastructure. And I think that the
main benefit of any PaaS, AWS Lambda or AWS API Gateway is (obviously) that
they're time saving and abstract the internals. In fact I use them in several
_small_ projects.

"Microservices without the Servers: the Uberization of IaaS as PaaS for SaaS"
Like when you say you have no carbon footprint because you don't own a car,
even though you call a taxi every time you want to go somewhere?
Are microservices different from SOA? Or is it just a more modern, streamlined
buzzword?
You say "microservices," but all I see is "omg, you realize inter-node latency
isn't a trivial component to ignore when building interactive services,
right?"
~~~
hyperpallium
Yes, microservices are just a rebranding of a SOA subset.
[http://martinfowler.com/articles/microservices.html#Microser...](http://martinfowler.com/articles/microservices.html#MicroservicesAndSoa)
But I think this direction is inevitable, and we'll soon see freemium
microservices.
Amazon's "Lambda" page (esp scroll down to the "benefits"
[https://aws.amazon.com/lambda/](https://aws.amazon.com/lambda/) ) shows it's
more like offloading some tasks (like worker threads in the cloud).
I had a play with the second (linked) app, SquirrelBin
[http://squirrelbin.com/](http://squirrelbin.com/) which can edit and run
javascript snippets. The latency is awful, 2-3 seconds for me (I'm in
Australia, but that should only add 200ms roundtrip or so). They seem to spin
up (reuse?) an entire instance for _each request_ \- it's incredible that it's
as fast as it is.
But the problem is the architecture of this specific app: the delay would be
fine if you could edit-run-loop code locally, without the cloud. But they
wanted to demonstrate quick development (for them) by just making a CRUD app,
using AWS Lambda existing http endpoints for PUT, POST, GET, DEL. So after
editing you have to save, load and run - and each one interacts with the
cloud. BTW the article about SquirrelBin

_They seem to spin up (reuse?) an entire instance for each request_
There are some clever platforms running on bare Xen (no direct OS) that can
spin up an entire instance and destroy it on every request pretty quickly.
[http://erlangonxen.org](http://erlangonxen.org) is a great example. 100ms to
boot your entire "system" for production usage.

jacques_chester
Here's how I deploy code, without having to modify it:
cf push myapp
It figures out the language/runtime I'm using (Java, Ruby, Go, NodeJS, PHP),
builds the code with a buildpack, then hands it off to a cloud controller
which places it in a container. My code gets wired to traffic routing, log
collection and injected services. I can deploy a 600Mb Java blockbuster using
8Gb of RAM per instance or I can push a 400kb Go app that needs 8Mb of RAM per
instance.
I don't need to read special documentation, I don't need special Java
annotations.
I just push. _And it just works._
I'm talking about Cloud Foundry. It runs on AWS. And vSphere. And OpenStack.
It's opensource and doesn't tie you to a single vendor or cloud forever.
I worked on it for a while, in the buildpacks team, so I'm a one-eyed fan.
Seriously: why are we still talking about devops? _It 's a solved problem_.
Use Heroku. Install Cloud Foundry. Install OpenShift. And get back to focusing
on user value, not tinkering.
Disclaimer: I work for Pivotal Labs, part of Pivotal, which donates the
largest amount of engineering effort on Cloud Foundry (followed by IBM).

As a note, I decided to look up CF based on this comment. This lead me to
cloudfoundry.org, which appears entirely devoid of content. Just useless talk
about "heavyweights" and so on. The menu didn't appear to have any links to
anything useful either. Clicking on products lead to a page with three product
names. Having visited the site, I'm actually now negatively disposed towards
it (but your comment outweighs my experience, and I'll still attempt to check
it out).
Granted I only spent a minute, but if this is a typical experience, I'm unsure
how anyone would come to the conclusion that there's any software worth using
there.

jacques_chester
Frankly, I agree with you. We suck at developer outreach. It bugs me.
Unless you know where to find the docs[0], they're not obvious. There's a
single master repo[1], but it's oriented at _deployment_ and works by
aggregating dozens of sub-projects[2] into a BOSH release and BOSH deployment.
... which requires you to know what the hell BOSH[3] is ...
So recently we started trying to make it easier. The best place to start
tinkering is Lattice[4], which is a cutdown extract of Cloud Foundry. or
Pivotal Web Services[5]. Or IBM BlueMix, I guess[6].

Thanks for the links, much appreciated! How does CF compare to go.cd? Will
there be a lot of setup work required?
~~~
jacques_chester
go.cd fills a different role. Funnily enough go.cd was the main CI system used
for Cloud Foundry, though it's being steadily replaced by concourse.ci.
Cloud Foundry is a bear to install because you will probably wind up needing
to wrap your head around BOSH, the IaaS orchestration tool. Once you get past
that hump it's relatively obvious. Getting past the hump is tough.
Bear in mind that it's a _complete_ PaaS. The kind of thing you bet your
company on (and our customers do). BOSH is a heavyweight system that predates
a lot of later tools like Terraform or Cloud Formation. On the other hand, we
use BOSH to update Pivotal Web Services to the latest cf-release every 2 weeks
or so and basically, nobody ever notices. It just works.
The easiest way to start is either Lattice or a public Cloud Foundry
installation. The former has the advantage of being easy to install on a
laptop, and it's intended for developers to tinker with. The latter has the
advantage that someone else ran `bosh deploy` and is provisioning the VMs that
Cloud Foundry runs on. Pivotal Web Service (based on AWS) and IBM BlueMix
(based on SoftLayer, I think) are the two main ones.
~~~
vacri
> _Getting past the hump is tough._
So... it's not a solved problem after all? :)
~~~
jacques_chester
Oh you :)
You only have to install CF once, not every time you deploy. After that it's
easy to upgrade. We do so on Pivotal Web Services every time cf-release is
incremented, which is approximately fortnightly.

daviding
I'm playing with these exact things now and it is very enjoyable so far.
My main worry is not on the technical side but on how things are charged for.
If I build something that starts to get used I am covered in terms of
scalability, but not in a way that protects me from 'cost scalability' so to
speak. I know I can set up billing alerts and hit a big 'shutdown' button in
response to high load, but what I don't think I can do is throttle these
services based on the money I want to budget/spend. With my own services I
have a hard cost limit, with a hard scalability limit, or rather I just accept
that my response times will go down or fail once I've allocated all I can
afford.
If there something for AWS in terms of 'cost throttling'? It may be a gap in
their services, especially for people want to build things that might get
traction?
~~~
bpicolo
As a small user, I've bemoaned the lack of 'cost throttling' for a while. I
spend minimally and don't want to worry about e.g. private key leaks that cost
a fortune, or some malicious traffic hitting my s3 hard.
~~~
aluskuiuc
One of the easiest mitigations to this is to not even create credentials that
have access to do anything that could run up a bill in any short amount of
time. Between the Console (access protected with an MFA token) and IAM roles,
neither you or your application ought to ever have to handle raw AWS secrets.
~~~
bpicolo
Yeah, I do use IAM roles heavily, 2fa, etc : )

Great to see Lambda stepping up their serverless game. We're big fans of this
approach and are hacking on something similar to this at StackHut[1], but:
* Mostly OSS to avoid lock-in
* Git integration
* Full stack specification (OS, dependencies, etc.)
* Python/ES6 support (Ruby and PHP coming)
* Client libs so you can call your functions 'natively' in other languages.

I think your pricing scheme[1] could put a lot of people off. I fall into the
category where I'd be fine on the free tier (< 10 private services), and yet I
don't _want_ a free service.
I know if it's free, then it's going to be under some kind of fair usage
policy, and you're going to rate limit me or have some kind of restrictions
eventually. There's no way it can be sustainably free if I start to push it
really hard. I'd prefer to just know the limits upfront, or have some kind of
usage based pricing.
[1]. [http://stackhut.com/#/pricing](http://stackhut.com/#/pricing)
~~~
pea
Hey Jake -- thanks for your feedback, that is really helpful.
We're going to add some better pricing. How would you like this to work?
\- per month, flat rate, ups w/ usage \- per request \- per compute / storage
We really like the idea of only paying for the compute you actually use a la
lambda; one of my gripes with Heroku was having to pay $x when the server was
only in use for short bursts. Why should I pay for downtime?
That said, we've actually had many people say they would prefer per month, as
it is more predictable and they are worried it could spiral out of control.
I would be super interested to hear your thoughts.
~~~
Jake232
I'm not sure that per-request would work; because the resources that a request
takes can vary wildly in resources used / time taken. PiCloud (somewhat
similar idea) used to charge based on processing time essentially (down to the
millisecond I believe).
I personally think that is the correct kind of pricing for something like
this; but monthly plans including X time/requests would likely be a good idea.

patsplat
The current problem with this architecture is the network cannot be used as a
security layer. Databases, search engines, etc need ports opened to the public
rather than to selected servers.
~~~
dikaiosune
If you're on a private network (like your own DC), I'd argue that network-
based security is a poor idea because then an attacker just needs to plug in
and have pretty easy access.
If you're on the public cloud, I'd argue that this is an even bigger problem
as you're then relying on VPC (or the equivalent) to always work correctly.
Why not ignore the networking and just build in robust security? Pubkey
authentication where possible, random long passwords where not? Retry limits
for clients, network intrusion detection, etc. To me, relying on the network
to keep you secure seems a bit like a crutch.
~~~
patsplat
This is an optimistic counterpoint.
However realistically nearly all persistence services such as MySQL, Postgres,
MongoDB, Memcache, ElasticSearch, etc either have been insufficiently hardened
as a public service or flat out are not intended to be used on a public port
and depend on the network for security.
There is not currently an option to connect an RDS database instance to a
Lambda function without opening said database instance up to the public. It's
a problem.
You are correct that SSH tunneling could be used to provide security but such
usage is not yet a standard approach.

It took about 2 months with support (Business support) and finally they chose

We created a new account with a new card and migrated our AWS infrastructure.

Lambda has a fairly generous free tier.
Here are the details on pricing:
[https://aws.amazon.com/lambda/pricing/](https://aws.amazon.com/lambda/pricing/)
You get up to 1M requests / month and 400,000 GB-seconds of compute time per
month.
A default lambda function uses 128 MB of ram (0.125 GB), which gives you about
3.2 M seconds of compute time (time actually spent executing requests) every
month for free.
Thus if you have functions that take 500 ms on average, and use the default
amount of RAM, you can process about 6.4 M requests in a month for a total
bill of $1.20.
Above the free tier limits you pay $0.20 per million requests, and $0.1667 per

Is there a particular reason why Amazon chose JavaScript? I'm seeing more and
more PAAS services going nodejs first/only and am wondering if there's an
underlying reason.
~~~

AWS Lambda supports nodejs and jvm-based languages (Java, Scala, Clojure,
etc.) directly, and lets you run Python, shell scripts, and arbitrary
executables as well. We started with nodejs because it worked nicely for
expressing our initial launch scenario, event handlers.
~~~
sandGorgon
yes - I am aware that you support Python, etc. .. but nodejs is your first
class language. For example, even your docs only mention nodejs (and java
recently) [1]
what is _even_ more interesting is that you felt it worked nicely for
expressing event handlers. Can you talk a bit more about that - very
interesting to see why not something like python or ruby. I know that nodejs
is a callback-oriented _framework_... was it the fact that you can test
locally on nodejs consistently versus what would be the expected output on
Lambda ?

~~~
rev_bird
I don't think servers have a lot to do with this -- when you go to a URL, and
a page gets returned, why does it matter where the data came from?
For example: Say you've got an AngularJS app sitting in S3 or something, and
your backend is a Node.js app running in Lambda. Google finds a link to
"random-new-social-network.com/profile/drinchev" somewhere and tries to index
it -- their request is routed to "random-new-social-network.com," where
Angular recognizes "/profile/drinchev" as a route to a profile for some user
named drinchev, pulls in the "profile" template, and spits out your profile,
where Google can read it and call it a day.
If you're talking about search engines getting along with Javascript-reliant
sites, that's a different story, but I don't think I see the problem.

Haiku R1/beta2 has been released - waddlesplash
https://www.haiku-os.org/news/2020-06-09_haiku_r1_beta2/
======
charlesdaniels
I'm glad to see Haiku is still making progress!
I really enjoy the visual style of Haiku. The look-n-feel of it seems better
to me than any other UI I've seen, and I say that as someone who never used
BeOS, so it's not the nostalgia talking.
It would be really cool if Haiku was able to get to a state were it's usable
as a daily driver. I think having an OS and interface more focused on a single
user at a graphical terminal rather than a multi-user system with graphics
tacked on would be positive.
BeFS also has some really great ideas that aren't replicated in other more
modern FSes, namely it includes database-like functionality that enables some
really neat features via a standardized interface, rather than hiding them
away in vendor-specific file formats. If you're interested, Practical File
System Design[0] uses beFS as it's example filesystem (and it's also a really
good book in general).

I also like the look of Haiku/BeOS, but to me it looks a lot like Apple
Platinum from Mac OS 8 and 9: [https://cdn.cultofmac.com/wp-
content/uploads/2017/10/39579b3...](https://cdn.cultofmac.com/wp-
content/uploads/2017/10/39579b3ce39de8d4e8e2b489a2a93880-780x585.jpg).
I'm curious what you like about it. I personally miss a lot of design things
that have fallen out of style.
On Windows, it feels like everything is blindingly white/soft grey with no
texture or borders to help my eyes focus. Transparency is used without regard
for its utility. Instead of using borders, they use space which ends up
wasting a lot of screen real-estate. The differentiation between active and
background window is very subtle.
macOS has many of the same issues. Scroll bars aren't shown unless you're
scrolling. You can change this behavior, but still. Background windows are
hard to differentiate from foreground windows. Transparency is used for
seemingly no reason.
That said, macOS does offer better design queues than Windows 10. The macOS
finder will use a slightly different color for the left panel than the main
work area. Windows 10 uses the same white for both areas drawing focus as if
they're equal. Buttons in macOS have a very subtle bump out to show that
they're buttons vs just being completely flat. There are usually small borders
between things.
Take this screenshot: [https://thehacktoday.com/wp-
content/uploads/2015/10/screensh...](https://thehacktoday.com/wp-
content/uploads/2015/10/screenshot-folder.png). There's no border between the
back/forward/up buttons and the content below. Everything is the same white.
Clickable items have no real indication that they're buttons. macOS:
[https://icdn2.digitaltrends.com/image/digitaltrends/import-m...](https://icdn2.digitaltrends.com/image/digitaltrends/import-
music-in-macos-catalina-finder-1.jpg). You can see more clear demarcations.
Buttons clearly stick out a little, the left panel is a different color with a
tiny border, the title bar is a different color with a gradient, etc.
Haiku's design harkens back to a day when we demarcated things. Haiku's active
windows are yellow while background windows are grey
([https://upload.wikimedia.org/wikipedia/commons/1/1d/Haiku_OS...](https://upload.wikimedia.org/wikipedia/commons/1/1d/Haiku_OS.png)).
This makes it instantly clear what is the top window. There are borders on
everything and a subtle beveled effect.
Is that the kind of stuff that you like about Haiku's UI? Is it something els?
~~~
cmrdporcupine
I agree with all your points. But worth pointing out that BeOS predates Mac OS
8 and 9. Not sure if there's a line of influence between the two, but uthere's
definitely a 1990s 'demarcated' design; not just with colour but with simple
visual elements.
And attention to physical placement. Windows 95 made a strange choice when it
placed the 'close' button next to minimize/maximize, making it entirely
possible to close-by-accident. OS X then strangely threw away the classic Mac
positioning and adopted something like Windows, and made this worse by
choosing in its first versions to make the function of the buttons unclear
until the mouse moved over them.
I really enjoyed Sun's "OpenLook" design back in the day:

It's very much a shame that licensing on Motif was so restrictive. At a time
when Unix desperately needed a standardized toolkit, the wrong moves were
made, and fragmentation was the result.

badsectoracula
Though IMO this misses the point of the OS which is the deep integration and
fast UI the native APIs allow that these cross platform applications (and any
application ported to Haiku through Qt and Java) ignore. There is no real
reason to use Haiku over some Linux desktop (you can even make XFCE look kinda
similar to Haiku/BeOS if you want) if the applications you use do not take
advantage of it.
~~~
waddlesplash
As a Haiku developer (and user, naturally!) I have to disagree. Obviously
native software would be preferred, just as it is on macOS, but I am pretty
sure that macOS users will tell you that they still prefer macOS, even if they
are using Firefox, or JetBrains, or Inkscape, etc., yes?
The Linux desktop is a horribly fragmented and fragile ecosystem. Haiku lacks
a lot of features the Linux kernel has, but the overall system architecture
and design is significantly cleaner and less fundamentally fragile.
~~~
badsectoracula
I never implied that the Haiku developers would dislike these applications, so
i'm not sure you being a Haiku developer has anything to do with your
disagreement.
And yes, macOS users probably also tell you that they prefer macOS, though
note that they also are often _very_ loud about preferring software that takes
advantage of their OS' features because this is why they use that OS.
The thing is, macOS has a much richer selection of software than Haiku has
(and most likely, ever have) so macOS users at least can fall back to those.
But if all you are going to use on Haiku is ported software that ignores
native APIs then what is the point of using an OS with less hardware support
and features?
The Linux desktop being fragmented doesn't mean much - your Qt application
ported to Haiku will also work on KDE perfectly fine and chances are even if
you limit your software selection to Qt-only applications, you'll still have
more applications to work with. Though that fragmentation is really a poor
description since there are standards you can rely on, like X11 - sure someone
might be using Gnome or XFCE or Window Maker or i3 or whatever as their
desktop, but applications do not target those environments, they target a
lower level of the stack that is shared among these and making an application
on XFCE doesn't mean it'll only run under XFCE.
So yeah, it might look fragmented, but unless you are some custom support
worker that tries to navigate someone through the UI via phone, that isn't
much of an issue in practice (and "in practice" is the important bit here
because the reasons i've seen people put forth for having Qt/Java applications
ported to Haiku and ignore Haiku's own APIs are all about practicality - which
ignores the elephant in the room which is that if you care about practicality
using Haiku in the first place wouldn't be a good choice anyway).
~~~
dundarious
Being a developer (and a user as they acknowledge), they have relatively deep
experience with the system and the benefits of "native" vs. ported apps.
Because of that, they have a reasonable basis of knowledge in order to dispute
your statement about the suitability of Haiku for someone using those apps, or
the benefits of using those apps on Haiku.
~~~
badsectoracula
They may have (i don't know) but they didn't dispute anything, they just said
that they disagree and the rest was about what macOS users would probably say
and something about how Linux is more fragmented and how in theory Haiku is
better but neither of those had anything to do with what i wrote.

I've tried Haiku a few times and liked it, but it feels like the beta label
has been around forever and is not doing them any favors. It's 2020, you're
not publishing software as a big-box release in stores, just cut a release
already and then keep iterating!
From Wikipedia:
_It wasn 't until September, 2009 that Haiku reached its first milestone with
the release of Haiku R1/Alpha 1. Then in November, 2012 the R1/Alpha 4.1 was
released, while work continued on nightly builds.[8] On September 28, 2018,
the Haiku R1/Beta 1 was released.[9] On June 9, 2020, Haiku R1/Beta 2 was
released._
Almost 11 years and it's still not out of beta?!
~~~
waddlesplash
What can I say? We have extremely stringent quality standards ;)
The "beta" label signified that we had implemented all the features we thought
mandatory for R1. Of course there are new ones in this release (like HiDPI
support or the NVMe driver) because we still want to use Haiku on contemporary
hardware, so changes still get made. But largely we are more oriented towards
stabilization and "usability", i.e. fixing bugs or minor enhancements that get
in the way of actually using Haiku.
But it's also the case that we do not get a massive amount of work done every
month; probably around or less than a "man-month" between the dozen or two
developers.

I used BeOS for a couple years in the 1990s as my exclusive OS. It had all the
software I needed at the time. I especially liked the feature where you could
clone your whole working system to another drive or partition, live. That
actually saved me on a couple occasions, I would perform a weekly backup of my
whole live system to a secondary drive.
It's so nice to see this project making great progress.

Haiku lags and will lag main stream operating systems regarding drivers for
hardware. But if they could make it run in Raspberry Pis, with one set of
hardware it would be awesome. A light weight operating system on a light
weight computer.
RPi's could be the killer "app" for Haiku.
~~~
waddlesplash
Honestly the main way we lag right now is missing sleep support (nobody has
attempted it) and 3D acceleration.
Otherwise, Haiku runs on modern hardware just fine. I have a custom build from
this year under my desk with an AMD Ryzen 7 3700X (8c16t), an NVMe drive, and
Haiku boots off the NVMe and runs great with all 16 threads. It even can
connect to the internet via the WiFi card on the motherboard.
~~~
hedora
I’m curious. I’ve long suspected hardware compatibility would get easier as
everything moves into the same package as the CPU.
Have things been playing out that way?
~~~
waddlesplash
Sort of. Things like USB, which past 1.0 has only one controller per
generation, released the current controller design in 2010 with the first
chipsets on the market in 2011. So that at least is less of a moving target
than it once was.
But, I mean, NVMe follows on SATA much like SATA followed on IDE, so on that
front things are not so different. And for WiFi, there is not a common device
interface for that, so each new generation of hardware from each manufacturer
requires a large chunk of new driver code. Haiku reuses FreeBSD's WiFi drivers
and 802.11 layer, but as you can see, they are having a hard time keeping up
(only recently was one developer hired part-time to work on it, I believe.)
So, it's kind of a wash, really -- on x86 commodity PC hardware, that is. Part
of the reason Haiku on ARM still has not taken off is how wildly diverse that
ecosystem is, especially how much of a moving target it is.

How does Haiku's accessibility story look like? Any plans for a screen reader?
Blind user here, I would like to try this out and see what all this fuss is
about, but I think I can't. Can someone explain what's so great about Haiku's
UI?
~~~
waddlesplash
(Haiku developer here.) The way the UI is structured, creating a screen reader
would not be too difficult, and I think one of our developers attempted it at
one point, but it was certainly never finished and is not usable right now.
Sorry :(
Beyond the spirit of and compatibility with BeOS, Haiku's advantages are being
full-fledged desktop operating system developed by a single team as a single
unit (that is, unlike Linux or the BSDs where the kernel, window manager, GUI
toolkit, application suite, etc. are developed by separate teams and combined
by yet other groups); and also our occasionally unique approach to systems
design and implementation (for instance, the Haiku package manager is based
around a union mount of block-compressed filesystem images.)
The UI itself is reminiscent of 1990s UIs (gradients, bevels, more saturated
colors), with a modern feel (modern fonts, antialiasing, etc.) The window
borders are not rectangular, but are instead yellow "tabs" which are only as
wide as their text is, and so windows from separate applications can be
"stacked" and used as a unit, like tabs within applications.
------

Interesting— two showstoppers for me fixed since Beta 1. USB 3 is now much
better supported including as boot devices, and NVMe drives are now also
supported. I might just be able to at least boot and see this! Judging by
this, the traction actually sounds decent. Wait - what? It’s 10+ years old.
Yes, but that was just two major improvements out of several, and during 20
months.

One of my first sour experiences with NTFS was the horror involved in learning
how to find which files have changed since some given time in a directory. I
expected a SQL-ish interface but...omg. omg.
The reason for tracking changes in files was for hot loading art assets into a
running program.
~~~

Yup, filesystems in general should have a database/SQL interface. I'm
currently using CouchDB and Apache Tika to index and search my files. It works
but there is no way people who are not programmers would enjoy using such a
system. It's extremely inelegant and requires constant context switching and
I'd much rather be using an operating system that had all this functionality
as part of the filesystem interface.

azinman2
Considering it's a small set of developers who all work part time re-
implementing an OS from the 90s that failed when it was a commercial entity
fully staffed, it's hard to imagine that they're super serious about it being
a "production" OS.
~~~
chipotle_coyote
A couple quick comments:
(1) While Be, Inc., failed, it's debatable whether it failed because the OS
wasn't good enough. It was certainly being used in commercial production in
certain places already -- not just by hobbyists. Steinberg was selling a BeOS
version of their (very high-grade and expensive!) audio production system,
Nuendo, and I actually _saw_ Level Control Systems' CueStation, an "audio
automation system" for Broadway-grade live performance systems, running on
BeOS in the wild -- it was running the control booth of Cirque de Soleil's
permanent installation at Disney World. BeOS was doing _shockingly_ well in
attracting commercial applications in 1997-1999 given its tiny user base --
what they were failing at was attracting hardware companies to ship pre-
installed systems. Be's management was dead set on the idea that "steady and
slow growth as a niche OS" just wouldn't do, and they needed to either be the
next Apple or die trying. And, when they punted on desktop BeOS in favor of a
custom version for what turned out to be the absolutely imaginary market for
internet appliances, they pretty much chose "die trying."
(2) I think it depends on what you mean by "production". I mean, it's probably
never going to be competing with Linux servers. But is it possible it could be
competitive with Linux as a desktop OS? Maybe. A few years ago I wouldn't have
been that optimistic, but they've done a tremendous job with ports.

I remember folks who would wax nostalgic about BeOS, and claim it trounced
Unix & Windows when it came to performance. Could anyone speak to the
technical strengths / interesting aspects of this OS?
~~~
kitotik
I think most of the perceived performance was a result of pervasive multi
threading, which was novel at the time.
For example, I remember being able to simultaneously play 5-6 mp3 files, load
a web page, play an mpeg video, and browse the local file system while having
complete UI responsiveness and no audible/visual glitches. This was pretty
much unheard of at the time, especially on modest consumer hardware (pentium 2
~350mhz IIRC)

People have tried it before, but all those projects are now defunct.
Ultimately it winds up being "just another Linux desktop environment", or even
a mere reskin of another DE. The kind of deep system integration that is
possible when the entire system is developed as one project is extremely
difficult, if not actually impossible, to do in the Linux ecosystem.

Crazy idea: Have you ever thought of porting your desktop environment to
Genode? ( [https://genode.org/](https://genode.org/) ) And fully integrating
their Sculpt into it? I mean, on Amd64 you are already binary incompatible, so
that wouldn't count as an argument against it.
~~~
waddlesplash
Someone suggested it (but then, the community is large enough that all far-
fetched-but-not-impossible ideas have probably been mentioned at one point or
another :)).
I don't really know what the differences between porting Haiku's userland to
that or to Linux would be. Everyone loves to make arguments about how
microkernels are so great and all, but there still isn't a major operating
system or distribution with a significant number of everyday users on one.
Plus, all of our same philosophical objections to using the Linux (or any
other kernel) as the basis for Haiku would still apply.

I get (I think) how this is different from a Linux desktop, being developed in
entirety as a single project, instead of being split into a kernel, and user-
space distro, and fragmented apps on top of that, but ... is there a tl;dr on
how this compares to (say) FreeBSD, which is another "kernel + user-space in
one package" thing?
~~~

FreeBSD still runs X11 and a bunch of other applications on top of it to get a
working desktop, and the result is ... even less pleasant than the Linux
desktop, according to some reviews:

wtallis
The domain name is _haiku-os.org_. Every page includes an "About" link at the

top.
They really couldn't make it any easier to figure out what Haiku is.
~~~
dmichulke
The news release doesn't show a thing about what it is nor is there a link.
The URL with an OS in the name tells me what category it is in but not the USP
(I don't really get that from the two sentences either but at least it's
something)
So I went looking (not via Home or About because usually they are useless,
YMMV) but via Documents.
So here I am, saying that it took me a while to figure out what it was.
~~~
vhodges
There is no USP really... it's an OpenSource reimplementation of
[https://en.wikipedia.org/wiki/BeOS](https://en.wikipedia.org/wiki/BeOS)
(before your time?). Haiku has been around in some guise or other since the
early 2000's.
BeOS was/is pervasively threaded and took full advantage of multiple cores (a
very novel thing when it came out - BeBox had two PPC processors).
Similar projects include: ReactOS (Windows 2000), AROS (AmigaOS), FreeDOS (MS-
DOS), FreeMiNT (Atari ST). I think there might even be one for OS/2
~~~
slantyyz
For all intents and purposes, if you had no exposure to BeOS, you won't really
get why this project exists.
It is so crazy to think that we could be living in a completely different
world today had Apple opted to acquire BeOS instead of NeXT.

Sigh. Probably will try it later. Did try the R1/beta1, and had to fiddle in
the BIOS to get usable output on secondary display (can't remember if i
managed dual-screen) on intel graphics. Liked the look and feel of it, mostly.
Because on the secondary display on 24"@1920X1200 the icons looked somehow
stretched wide, but just a little. Not so on the internal 13"@1280x800.
Question is: what to do with it? How stable is the FS? Where are the
videos/intros which _really_ show what i can do with it, which i can't with
other desktops? Haven't found a really compelling reason so far. (Hmmm, seems
like they updated their slideshows and list of videos...)

Haiku looks like an interesting project. I like the concept and the consistent
design, but ... it is still missing one critical feature ... a viable business
model.
Linux is an example of what to expect without this critical piece. Decades of
manhours from some of the best and brightest, millions of lines of code ...
and a miniscule marketshare on the desktop.
~~~
agildehaus
It's not a business. Why does there have to be a business model?
~~~
jqpabc123
It doesn't need one --- as long as it only aspires to be another hobbyist OS
with a miniscule desktop user base.
~~~
agildehaus
It aspires to be something the developers enjoy hacking on and using, which is
the very reason it exists at all. Why you seem to think it needs to be more
than that is puzzling.
I'm sure the developers would love for it to be more than that, but there's a
limit to what can be done and it's ASTONISHING what they have done.

At the risk of pounding the Jobs-is-dead meme too hard, this reminds me of a
good story I read recently about Steve Jobs:
_Jobs tells the VP that if the garbage in his office is not being emptied
regularly for some reason, he would ask the janitor what the problem is. The
janitor could reasonably respond by saying, "Well, the lock on the door was
changed, and I couldn't get a key."
An irritation for Jobs, for an understandable excuse for why the janitor
couldn't do his job. As a janitor, he's allowed to have excuses.
"When you're the janitor, reasons matter," Jobs tells newly minted VPs,
according to Lashinsky.
"Somewhere between the janitor and the CEO, reasons stop mattering," says
Jobs, adding, that Rubicon is "crossed when you become a VP."_[1]

We can go back further than that. Hal Geneen was the CEO famous for expanding

management. His favourite saying was,
“Managers must manage.” As in, your job as a manager is to overcome the
obstacles, not to use them for excuses. What do you manage if not the
impediments to success?

This post reads more like the author trying to come to terms with his own
tortured, confrontational, win/lose outlook on running a company. It also
reads like a case of passive/aggressive venting on a portfolio company CEO who
is driving him nuts, or the aggregate of several such cases.
In any case, this is not useful advice. And patently untrue. When the chips
are down, people do care, and people help out, if you explain the challenges
you are facing and the odds you are up against. Not least of all, "your mama".
The article also strikes me as a misinterpretation of the quote and the
exchange between owner and coach. I would read it differently... the coach is
at his wits end, calls the owner for advice, and the owner doesn't merely say
"nobody cares"! He says "just coach your team". Meaning, don't worry about all
the things you thought you were going to do (with the team roster you thought
you had) and just hang in there, stick to your core strength (coaching) and do
your best to make it work.
No wonder the author has anguished posts on his blog like "What’s The Most
Difficult CEO Skill? Managing Your Own Psychology" wherein we read such gems
of wisdom as "It’s like the fight club of management: The first rule of the
CEO psychological meltdown is don’t talk about the psychological meltdown."
Not really. The first rule is relax, don't take yourself so damn seriously.
Actually, there are no rules. Isn't that why you became CEO?
People infected with attitudes like this suck all the life and joy out of
doing business. It's not all about people standing around yelling "no excuses!
yo' mama don't care!" at each other. Carrying around excess psychological
freight like this only slows you down, makes you hate yourself and the
industry, etc. If there are problems, you deal with them. Often times, solving
problems means figuring out the parameters of the difficulty, putting all the
resources you can against the problem, and then going and finding the right
people who care to help you out with the rest.
~~~
Cushman
I like this. I think there's a common fallacy where people want to think that
other people are more selfish and uncaring than they are. Maybe it makes it
all seem more explicable?
But it's not true. Humans haven't managed to colonize the whole planet because
we're so mean to each other-- that doesn't even make sense. The physical
universe is impartial and uncaring; people have succeeded primarily because,
most of the time, we _aren't_.
We have access to such great information sources these days, we hear so much
about war, crime, and poverty, it's easy to forget that we actually live in
the most peaceful, prosperous times that mankind has ever seen. It's so easy
to get ahead for a little while by screwing the other guy, we forget that the
only reason any of us exist is because a relatively short time ago, and ever
since, some apes realized that if they just put aside their differences and
worked together for a little while, they could conquer the world. _And they
were right._
A little bit of trust, humility, and respect for humanity goes a long way.
Have a problem? Tell your mother. She probably can't do much to help, but
she'll _care_ , and that is way more important than people think.

I think this is great advice for a CEO's emotional well being. But it isn't
true. I know I care a ton about the challenges our portfolio companies face
and I know many other stakeholders who do too. Capitalism isnt uncaring
~~~
dmor
Sounds like some good tough love for CEOs (and everyone else really) who care
too much. That's probably most of them, and a whole lot of employees,
investors, and even customers too.
IMO the why matters, but only for a moment, and then the "what are you going
to do next?" has to become the focus. That way caring so deeply doesn't become
unproductive -- you grieve the pain of mistakes and unfortunate outcomes for
no more than a minute or two ("and this too will pass") and then keep moving.
Startups are like sharks, if we stop moving we die.

This is great advice that applies to life as much as to work.
Just changing the last three words of the last paragraph gives:
"All the mental energy that you use to elaborate your misery would be far
better used trying to find the one, seemingly impossible way out of your
current mess. It’s best to spend zero time on what you could have done and all
of your time on what you might do. Because in the end, nobody cares, just LIVE
YOUR LIFE."

dredmorbius
No. You should care.
If it's your own team/project/company, odds are very good that it's not the
things you're doing right that are in the way, it's the things that you're
doing wrong, or that are going wrong. A systematic analysis of failure modes
("5 whys" in Scrum) is going to help.
Education is learning from other people's mistakes. If the it's another
organization's problems or failures, then learning from them is a great way to
avoid making the same mistake yourself. When forwarding the recent AmEx
information disclosure story to my team, I added the question "do we have a
'?debug=true' feature?"
comp.risks has been one of my go-to reading sources for a few decades. There's
a reason for that.
To point on the story: identifying causes (and corrections) for injuries has
been a big part of professional sports in the past decade. Moneyball is a
story of doing highly systematic analysis of what it takes to win (and
avoiding the mistakes leading to losses), in a manner any scrappy startup can
appreciate: not enough money.
And much of the story of early industrial organization (and risk management)
was taking a statistical approach to production (and loss) and realizing that
though both were based on stochastic principles, this did _not_ mean that the
conditions or outcomes were unmanageable.

Sure they care. Sports fans are easier on a coach if they know he's got an

This is a great lesson in capitalism. When you're the boss, nobody gives your
partial credit for good attempts. Either the team succeeds and everyone is
happy, or they don't, and the boss takes the fall.
Taking this a step beyond the intended message (of football and business),
this shows an interesting dichotomy in education in jobs. In many countries
(example: Japan, France) school is results based, with admissions based soley
on rigorous exams. The real world is softer based more on credentials and
connections than results. Compare that to the US... Being a good football
player (or trombone player) can help you get into school, but the real world
is much less forgiving.
Our economy has tough times, but the unforgiving cruel world helps us stay
strong.

This should not stop at the CEO level, it needs to apply to every job within
the company, at every level.
Nobody cares about your excuses, whoever you are. Everyone's job involves
goals, milestones and deadline. If you are performing you deserve commensurate
rewards, if you are failing nobody should care to hear your excuses - only
what could you fix and perhaps why you believe you deserve another chance.
The performance of the CEO and overall company performance depends on everyone
pulling their weight. If the CEO does not enforce accountability throughout
the entire organization, he/she is heading for failure and nobody would care
about their sorry fate!
~~~
coffeemug
Most employees have a very different mindset. It seems that a company composed
only of people who understand and follow the 'nobody cares' principle would be
a perfectly operating entity where everyone always smoothly goes in the right
direction, but I'm not actually convinced that's possible. 'Nobody cares'
personal philosophy is very much correlated with alpha personalities, and you
can't have a team where everyone is an alpha - they'll rip each other apart
with conflicts. It's very tricky to balance this well - I'd like to see how
different leaders do it in organizations of different sizes.
~~~
nostrademons
The incentives at a typical corporation are also not setup to encourage
"nobody cares" attitudes. Employees are paid whatever the results are, unless
they do something egregiously bad. They have every incentive to care about
their effort and motivations - that's what they get fired for - and no
incentive to care about results. That's diametrically opposed from an equity-
owning cofounder (who basically can't be fired, unless the board forces them
out) but doesn't get paid anything unless the company succeeds.
You could argue that this is the _reason_ why anyone would accept a salaried
employment position. In a well-run knowledge organization, employees have just
as much freedom as startup founders do. The difference is risk assignment:
under an employment agreement, the employer assumes the risk (and reward) that
the product may fail despite the employee's best efforts, while in a startup,
the founder assumes the risk that the company may fail for reasons outside his
control. (The incentives issue actually falls out of this as a form of moral
hazard.)
Note that the alternative of paying everyone by results doesn't always work
either. Many financial firms use this approach. The problem is that
realistically, in a decent-sized organization, people _don't_ have a
measurable effect on outcomes, and results will be dominated by randomness
anyway. If you pay for results but results are not under the worker's control,
you end up incentivizing risky behavior, because the worker's upside is
potentially unlimited but their downside is generally capped at "everything
they own". This was the problem at Enron, LTCM, and many hedge funds in the
financial crisis.

Is this meant to be taken as advice or something? Because it's useless advice.
He could have at least said something like, "Be prepared for the day when all

prepared to rebuild from scratch. Be prepared to get a carton of Tums and make
the tough decision that gives you a bloody ulcer."
~~~
daeken
I think you completely missed the point. The point is this: nobody cares why
you failed, just that you failed, so put your energy towards finding a way to

Tesla and Tucker – Similarities Between Automakers - jonbaer
http://www.popularmechanics.com/cars/a21094/what-tesla-needs-to-learn-from-tucker/
======
Animats
The law here is the FTC's "Mail Order Rule".[1] Properly, Tesla allows
consumers to cancel your order at any time and receive a full refund. The
other requirement is that if Tesla misses their ship date, they have to send
the consumer a letter with a new ship date and an option to cancel. That part
is "opt-out". If, 30 days after the original ship date, the product hasn't
shipped, a refund has to be sent unless the customer explicitly requests
otherwise. That part is "opt-in". The seller can't just keep the money at that
point.
This is why, if you're selling online, you have to make sure not to take
orders you can't fill in time. In the early days of the Internet, this was a
big problem, because many sites had online ordering systems that had no
connection to inventory control. By now, everybody with a clue knows to check
inventory in the shopping cart program.

GM and Ford are drastically less powerful today than they were in Tucker's
time. By 1945-1950, GM was already the global leader in auto sales, and of
course Ford had been a juggernaut for some time as well.
That's the biggest difference.
Toyota, Honda, BMW, Daimler, Volkswagen, Hyundai, Nissan, Mazda - the
combination of those companies effectively neutered the old GM / Ford
political monster. It sucked the money out of the old Detroit political
machine, making it far less fearsome and influential in DC.
The GM / Ford that Musk is facing off against, is a joke compared to what it
used to be able to bring to the table in terms of abusing the system to stop
competition.
~~~
Shivetya
However as GM has proved that they can pivot quickly and bring a product to
market faster than Tesla. They have the supplier relationships needed as well
as the manufacturing and testing expertise to do so. They key is having
management that wants to do it.
I suspect Ford could as well but their leadership isn't as willing to change
direction as GMs does.
~~~
Grishnakh
Perhaps, but GM also has a worse reputation than Ford among buyers. Ford's
reputation among the American brands is the best, while GM's is not that
great, though Chrysler's is even worse.
If I want to buy a reliable, high-quality car that I know is going to last 10
years and not have the interior plastics all looking nasty and faded and
falling apart after a mere half-decade, GM is one of the last brands I'd think
of. No one thinks that Cadillacs are serious competition to real luxury cars
like Mercedes.
I think Tesla would do much better partnering with a Japanese automaker. They
know how to build high-quality cars in high volume, and they have great
reputations too, which is important if you're trying to sell $100k cars.
~~~
Grishnakh
I'll also add that if they have to partner with an American automaker, Ford is
surely the best choice as long as they don't stick that ugly blue oval logo on
their cars. Ford has a lot of experience partnering with other brands in
mutually-beneficial relationships: they did it before with both Volvo and
Mazda. In both cases, it seems like all 3 companies benefited from the
arrangement.
------
S_A_P
The article is ok I guess. Although I think this is more a book plug than true
analysis. I've often thought of the tesla/tucker parallel and how hard it is
to get a foothold in a capital intensive business as a start up. However I
don't think the parallels stick. Tesla has built and delivered a sizable
number of cars. I think the political influence of the big 3 is much lower now
as well. For tesla, I think that it's survival hinges upon delivering the
model 3 on time and at high quality. Along with a lot of other things going
right as well. I probably make about 50k too little to comfortably afford a
model x but I would love to own one some day. Quirks and all.
~~~
gutnor
> I think that it's survival hinges upon delivering the model 3 on time and at

... and in sufficient quantities. They have proven the technology, the
approach and the readiness of the market. The last thing they need to prove is
their capacity to scale.
If they achieve their target (i.e. Model 3 generally available in 2018), they
will have built a serious lead over the competition - meaning several years
(at least 2) on that sweet sweet market unchallenged.
Of course, Tesla has failed to deliver in time, at expected price or in
expected quantities before. Time will tell.
~~~
S_A_P
Agree. This is the biggest risk. Right now I think they have enough cache that
I would jump to electric for them where I may be too skeptical to buy an
electric ford. Delivering high quantity with high quality on time will almost
guarantee success.

Why are people being so critical about this work? Sure, the blog post provides
a simplified picture about what the system is actually capable of, but it's
still helpful for a non-ML audience to get a better understanding of the high-
level motivation behind the work. The OpenAI folks are trying to educate the
broader public as well, not just ML/AI researchers.
Imagine if this discovery were made by some undergraduate student who had
little experience in the traditions of how ML benchmark experiments are done,
or was just starting out her ML career. Would we be just as critical?
As a researcher, I like seeing shorter communications like these, as it
illuminates the thinking process of the researcher. Read ML papers for the
ideas, not the results :)
I personally don't mind blog posts that have a bit of hyped-up publicity. It's
thanks to groups like DeepMind and OpenAI that have captured public
imagination on the subject and accelerated such interest in prospective
students in studying ML + AI + robotics. If the hype is indeed unjustified,
then it'll become irrelevant in the long-term. One caveat is that researchers
should be very careful to not mislead reporters who are looking for the next
"killer robots" story. But that doesn't really apply here.

Is it wrong to be critical of research? Back in my previous life of doing
basic research I scrutinized papers left and right.

Hype is an interesting thing especially when it comes from laymen.

As someone familiar with the field, you likely know this already, but the
similarities between the Karpathy post from 2015 and this work from OpenAI is
likely because Karpathy is a founder and lead researcher at OpenAI.

I don't know, but this seems a bit hyped in places.
They start with:
> Our L1-regularized model matches multichannel CNN performance with only 11
> labeled examples, and state-of-the-art CT-LSTM Ensembles with 232 examples.
Hmm, that sounds pretty impressive. But then later you read:
> We first trained a multiplicative LSTM with 4,096 units on a corpus of 82
> million Amazon reviews to predict the next character in a chunk of text.
> Training took one month across four NVIDIA Pascal GPUs
Wait, what? How did "232 examples" transform into "82 million"??
OK, I get it: they pretrained the network on the 82M reviews, and then trained
the last layer to do the sentiment analysis. But you can't honestly claim that
you did great with just 232 examples!
~~~
derefr
This actually demonstrates something very interesting, I think: you can take
an ML model trained with the "low-level prerequisite knowledge" of a subject,
and then _very quickly and easily_ teach it a high-level concept that relies
on that knowledge.
Which, now that I think about it, makes the human brain and its amazing
adaptive general-game-playing abilities a bit less mysterious. Since _we
humans_ all have these huge corpuses of sense-data we've been receiving
reinforcement signals about since birth, we've likely built up all sorts of
low-level models which we just use to predict the world for reflex responses a
little bit better and faster (speech models so we can respond to what people
are saying even as they're still saying it, visual models so we can throw
spears where lions are _going_ to be instead of where they are, etc.) But
those low-level predictive models make it nearly effortless to build higher-
level models.
I wonder if we'd take a giant leap forward in AI if we just managed to
scan+emulate a regular animal brain (say, of a rat), and then built the AI as
a neocortex-equivalent for that brain. It would have instant access to
thousands or millions of pre-trained low-level predictive models, which it
could easily discover as having outputs correlated to success and thus "attach
to" during its own training.

emcq
What you describe is exactly what practitioners in the field have been doing
for years. I think that's why the parent is a bit puzzled at the publication,
as it's difficult to understand what's novel.
~~~
Cybiote
Yes, I agree with you but with a caveat. Semi-supervised learning is well
known but has, I'll argue, recently fallen out of fashion in favor of throwing
gallons more of labeled data at a really big neural net, crossing your fingers
and hoping for the best. Usually, the neural net is either a really big conv-
net with a novel architecture or a biLSTM with some elaboration on attention
(which is actually closer to memory/state).
Most of the time, in neural net land, what people are doing with the fine
tuning part is taking a model trained on looaads of supervised data, chopping
off the head and using those features to train on smaller data. This OpenAI
method is different in that it used patterns it learned on its own, instead of
the recently more common technique of features extracted from a heavily label
trained model to reduce the supervised learning burden in a nearby domain.
Arguably yes, this is an ancient technique but it has mostly been forgotten
when it became clear that many problems are surmountable with a large enough
helping of GPUs and a small moon's worth of data. OpenAI's is a good idea
because it makes you say 'yeah that's obvious, pretrain a simple char rnn on
loads of free text and oh wait, why has no one tried this before!?'
What is interesting here is that such a straight forward method compares so
well to glittering methods that laboriously advanced the state of the art.
What I also found surprising was that there was a 'neuron' that was tracking
something very close to sentiment. Why?
A bit of thinking and I came to a simple idea. One way of looking at the LSTM
in the practical setting (as opposed to a theoretically Turing Equivalent
thing) is as a really big finite state rube goldberg machine. In learning to
predict the next character, it makes sense that one set or part of a set of
states it can enter/track is extremely correlated with what we humans call
sentiment in review text.
In summary, the trained model can be thought of as a computable theory of
amazon reviews that also works really well on IMDB reviews (and probably short
but probably not sarcastic text reviews in general).
~~~
dnautics
thanks for clarifying this- it isn't _transfer learning_ at all, more like the
techniques like, digging through LSTMs _post hoc_ to find the neuron
responsible for opening and closing quotation marks (insert karpathy youtube
vid here), except for a more "high level" feature - in this case, sentiment.
------
srush
If you are interested in looking at the model in more detail, we (@harvardnlp)
have uploaded the model features to LSTMVis [1]. We ran their code on amazon
reviews and are showing a subset of the learned features. Haven't had a chance
to look further yet, but it is interesting to play with.

at the moment, AI short stories are derivative, so it's unlikely. They may

they're not completely novel.

So char-by-char models is the next Word2Vec then. Pretty impressive results.
It would be interesting to see how it performed for other NLP tasks. I'd be
pretty interested to see how many neurons it uses to attempt something like
stance detection.
_Data-parallelism was used across 4 Pascal Titan X gpus to speed up training
and increase effective memory size. Training took approximately one month._
Everytime I look at something like this I find a line like that and go: "ok

~~~
rspeer
Yeah, part of what let word2vec make such a splash that it became the one word
embedding model everyone has heard of, is that the word2vec team released
their model.
This is a really cool example OpenAI has, but I don't know why I should
ultimately care about their character model more than anyone else's if all
we've got is their description of how cool it is.
I hope OpenAI defies their reputation for closedness and releases the model.

It's very difficult to understand what the contributions are here. From what
I've read so far this feels more of a proposal for future research or a press
release than advancing the state of the art.
* Using large models trained on lots of data to provide the foundation for sample efficient smaller models is common.
* Transfer learning, fine tuning, character RNNs is common.
Were there any insights learned that give a deeper understanding of these
phenomena?
Not knowing too much about the sentiment space, it's hard to tell how
significant the resulting model is.
~~~
kleiba
* _advancing the state of the art_
It says right at the top: "we get 91.8% accuracy versus the previous best of
90.2%" on a standard sentiment corpus. In addition, their method needs less
training data than previous approaches.
* _Were there any insights learned that give a deeper understanding of these phenomena?_
The main appeal lies in the fact that a model trained on a (1) different and
(2) very general task basically "in passing" also learned to predict sentiment
(i.e., a specialized task that more or less arose from the domain the general
model was trained on), and pretty much through a single neuron (out of the
4096 used). The authors speculate that this might be a general effect that
could also be transferred to other prediction tasks.
~~~
emcq
If the main contribution here is the quality of the model and its interesting
and powerful representation of text, I hope OpenAI does something
distruptively different and releases the weights and trained model.
The accidental sentiment neuron is a function of the model, distribution of
the input dataset, and the optimizer finding nice saddle points. Insight into
these foundational components would make these results amazing. It sounded
like training on other datasets doesn't have the same sentiment properties,
which provides a lever to explore these concepts more.
At the moment it feels like the Google cat neuron. It attracted a lot of
intrigue but the individual contribution from that in terms of research was
more on the infrastructure side, and few people seem to refer back to that
publication at this point.
That said OpenAIs mission in itself doesn't necessarily require novel
research. For example, the gym is fostering a competitive atmosphere for the
community to work on RL which hopefully leads to more progress in the field.
Training a model for a month is difficult and if it has captured interesting
phenomena it seems in the interest of the community to release the weights and
model. It would be hard for the community to reproduce this without a month of
compute and 83M Amazon reviews.

wackspurt
(Apologies for the slightly incoherent post below)
I've been noticing a lot of work that digs into ML model internals (as they've
done here to find the sentiment neuron) to understand why they work or use
them to do something. Let me recall interesting instances of this:
1\. Sander Dieleman's blog post about using CNNs at Spotify to do content-
based recommendations for music. He didn't write about the system performance
but collected playlists that maximally activated each of the CNN filters
(early layer filters picked up on primitive audio features, later ones picked
up on more abstract features). The filters were essentially learning the
musical elements specific to various subgenres.
2\. The ELI5 - Explain Like I'm Five - Python Library. It explains the outputs
of many linear classifiers. I've used it to explain why a text classifier was
given a certain prediction: it highlights features to show how much or little
they contribute to the prediction (dark red for negative contribution, dark
green for positive contribution).
3\. FairML: Auditing black-box models. Inspecting the model to find which
features are important. With privacy and security concerns too!
Since deep learning/machine learning is very empirical at this stage, I think
improvements in instrumentation can lead to ML/DL being adopted for more kinds
of problems. For example: chemical/biological data. I'd be highly curious to
what new ways of inspecting such kinds of data would be insightful (we can
play audio input that maximally active filters for a music-related network, we
can visualize what filters are learning in an object detection network, etc.)

I would imagine stuff like sarcasm is still out of reach though. It seems hard
for humans to understand it in text based communication. Also using anything
out of the standard sentimental model might throw it off. "This product is as
good as <product x> (where product x has been known to perform bad." I am just
trying to think of scenarios where a sentimental model would fail.
Sentimental neuron sounds fascinating too. I didn't realize individual neurons
could be talked about or understood outside of the concept of the NN. I am
thinking in terms of "black box" its often referenced to in some articles.
Since one of the research goal for openai is to train language model on
jokes[0], I wonder how this neuron would perform with a joke corpus.

Yes, I agree. I recall seeing such individual neuron analysis before in
Karpathy's "The Unreasonable Effectiveness of Recurrent Neural Networks". He
takes a char-rnn that was training to predict the next character for source
code and finds neurons that have learned to do paranthesis/bracket
opening/closing.

aabajian
I'm trying to understand this statement:
"The sentiment neuron within our model can classify reviews as negative or
positive, even though the model is trained only to predict the next character
in the text."
If you look closely at the colorized paragraph in their paper/website, you can
see that the major sentiment jumps (e.g. from green to light-green and from
light-orangish to red) occur with period characters. Perhaps the insight is
that periods delineate the boundary of sentiment. For example:
I like this movie. I liked this movie, but not that much. I initially hated
the movie, but ended up loving it.
The period tells the model that the thought has ended.
My question for the team: How well does the model perform if you remove
periods?
~~~
jcoffland
Why would that matter? Human understanding of sentiment would also go down if
you removed vital information such as punctuation.
~~~
aabajian
My point would be to see how much the model is relying on punctuation. It
could provide insight as to why character-based models outperform word-based
models for sentiment analysis.

Can someone explain what is "unsupervised" about this? I'm guessing this is
what confuses me most.
I think this work is interesting, although when you think about it, it's kind
of normal that the model converges to a point where there is a neuron that
indicates whether the review is positive or negative. There are probably a lot
of other traits that can be found in the "features" layer as well.
There are probably neurons that can predict the geographical location of the
author, based on the words they use.
There are probably neurons that can predict that the author favors short
sentences over long explanations.
But what makes this "unsupervised"?
~~~
fiter
I wouldn't expect that the neurons are orthogonal on a set of features which
we find interesting (sentiment, geographical location). They could be bound up
in some other basis of features that we do not find interesting. Other people
do not expect this because there are papers about how to incentivize neurons
to correspond to interesting features.
~~~
wackspurt
>> Other people do not expect this because there are papers about how to
incentivize neurons to correspond to interesting features.
Could you clarify that statement? Are you saying that it was unusual for this
group to find such a neuron? Also, I did not know that there are papers on how
to incentivize neurons to correspond to interesting features. Could you please
give me some references on those?
~~~
fiter
The paper I was thinking of is called: "InfoGAN: Interpretable Representation
Learning by Information Maximizing Generative Adversarial Nets"[0]. I do not
have experience training and investigating neural nets, but from what I read
in that paper, there's no reason to presume you'll find neurons that represent
a feature you're interested in. In the paper they alter the reward function to
get neurons that correspond to the features they are interested in.

I think it's fair to criticize this blog post for being unclear on what
exactly is novel here; pre-training is a straighforward and old idea, but the
blog post does not even mention this. Having accessible write ups for AI work
is great, but surely it should not be confusing to domain experts or be
written in such a way as to exacerbate the rampant oversimplification or
misreporting in popular press about AI. Still, it is a cool mostly-
experimental/empirical result, and it's good that these blog posts exist these
days.
For what it's worth, the paper predictably does a better job of covering the
previous work and stating what their motivation was: "The experimental and
evaluation protocols may be underestimating the quality of unsupervised
representation learning for sentences and documents due to certain seemingly
insignificant design decisions. Hill et al. (2016) also raises concern about
current evaluation tasks in their recent work which provides a thorough survey
of architectures and objectives for learning unsupervised sentence
representations - including the above mentioned skip-thoughts. In this work,
we test whether this is the case. We focus in on the task of sentiment
analysis and attempt to learn an unsupervised representation that accurately
contains this concept. Mikolov et al. (2013) showed that word-level recurrent
language modelling supports the learning of useful word vectors and we are
interested in pushing this line of work. As an approach, we consider the
popular research benchmark of byte (character) level language modelling due to
its further simplicity and generality. We are also interested in evaluating
this approach as it is not immediately clear whether such a low-level training
objective supports the learning of high-level representations." So, they
question some built in assumptions from the past by training on lower-level
data (characters), with a bigger dataset and more varied evaluation.
The interesting result they highlight is that a single model unit is able to
perform so well with their representation: "It is an open question why our
model recovers the concept of sentiment in such a precise, disentangled,
interpretable, and manipulable way. It is possible that sentiment as a
conditioning feature has strong predictive capability for language modelling.
This is likely since sentiment is such an important component of a review" ,
which I tend to agree with... train a on a whole lot of reviews, it's only
natural to train a regressor for review sentiment.

> The model struggles the more the input text diverges from review data
This is where I fear the results will fail to scale. The ability to represent
'sentiment' as one neuron, and its ground truth as uni-dimensional seems most
true to corpuses of online reviews where the entire point is to communicate
whether you're happy with the thing that came out of the box. Most other forms
of writing communicate sentiment in a more multi-dimensional way, and the
subject of sentiment is more varied than a single item shipped in a box.
In otherwords, the unreasonable simplicity of modelling a complex feature like
sentiment with this method, is something of an artifact of this dataset.

What they have done is semi-supervised learning (Char-RNN) + supervised
training of sentiment. Another way to do is semi-supervised learning
(Word2Vec) + supervised training of sentiment. If first approach works better,
does it imply that character level learning is more performant than word level
learning?
------
mdibaiee
As far as I understand, it means that there must be a relation between a
character's sentiment and what the next character can (/should) be for neural
network to use this as a feature, am I right?
Does this mean we have unconsciously developed a language that exposes such
relations?
~~~

They muse about the reason behind the sentiment neuron in the paper.
"It is an open question why our model recovers the concept of sentiment in
such a precise, disentangled, interpretable, and manipulable way. It is
possible that sentiment as a conditioning feature has strong predictive
capability for language modelling. This is likely since sentiment is such an
important component of a review."
They go on to frame that as an important consideration for further work like
this:
"Our work highlights the sensitivity of learned representations to the data
distribution they are trained on. The results make clear that it is
unrealistic to expect a model trained on a corpus of books, where the two most
common genres are Romance and Fantasy, to learn an encoding which preserves
the exact sentiment of a review."
I'm wondering if a "funniness" neuron could be discovered in a model trained
on millions of jokes of various funniness, or what sorts of undiscovered
meaning there is in other neurons in this model.

For me, Fenix on Android is the worst update ever. I use Firefox as my main
browser on Android since almost 10 years and my whole mobile workflow depends
on the awesome Tab Queue-feature (new tabs from other Apps like
Twitter/Slack/Mails are opened in the background).
With Fenix, Mozilla decided to just abandon that feature. Issues are closed,
it got removed from the feature list [1] and further questions are ignored. I
fully understand that you can't keep every feature everywhere, but this was
THE main benefit of Firefox (besides ublock) for me and if you look at
GitHub/Reddit/Twitter I am not the only one.
Now I have to stick to an outdated browser because of an (for me) completely

Hopefully they changed the address bar back to be non-Chromeified.

Haven't used it in a while, but when I did it was always easy to switch the
behavior (for a power user, and I think the omnibar is much more appealing to
non power users as it's visually simpler, big, and easier to click — unifying
the search and address bar _is_ what you're talking about, right?).
~~~
ProAm
Its not easy to switch back anymore and breaks a lot of functionality if you
do. But its crazy that you have to accept serious UI/UX changes to get
security fixes too.

What functionality does it break?
> But its crazy that you have to accept serious UI/UX changes to get security

It is sad, but it basically seems par for the course for big, semi-commercial
software. I don't like Mozilla, but I appreciate them making an alternative to
the massive Chrome near-monopoly that's not only just as fast and lighter but
competitively easy to use for normal people. I personally switched to Waterfox
years ago, and Pale Moon not long after that. It receives some security fixes
slightly after FF (they're fixed after Mozilla publishes the issue), but some
of them are not applicable
([http://www.palemoon.org/releasenotes.shtml](http://www.palemoon.org/releasenotes.shtml))
. Overall, to me then Pentadactyl is worth worse than that, and I think you
might love the UI.

> It is sad, but it basically seems par for the course for big, semi-

I totally get why they do it too, Im a big Mozilla fan and have been for a
long time. Im glad there is browser competition, I love their take on Add-ons
and allowing the user to make decisions for themselves. They are fighting the
good fight, Im just expressing my opinions on things I don't like, but Im
still going to use FF. I did stop upgrading with version 76 because it was
just too much change and disruptive enough for me to downgrade and turn off
the installer.
Ive never seen Pentadactyl, Ill check it out.

Or not, because that's just FUD.
`dom.workers.serialized-sab-access` is the flag they've put in so that way
they can disable concurrent execution of JS threads that share memory in case
a novel cross-process attack shows up. Spectre is purely an in-process attack
and the whole article that comment is attached to is about the work they did
to enable shared memory while defending against Spectre.
`dom.workers.serialized-sab-access` does not affect Spectre. It appears to be
intended for preventing a novel cross-process attack from leveraging shared
memory in other processes into becoming a high-resolution timer.
Also note that threads that have access to shared memory in Firefox 79 also
have access to the full high-resolution performance.now(), and flipping
dom.workers.serialized-sab-access doesn't affect that.

Every few versions I would check Firefox on macOS just to see if they make any

And... Firefox 79 with one active tab is taking 6x more energy than Safari
with 20+ tabs.

They're mostly thumbnails of Web sites people have recently visited or visited

Thumbnails are buggy. Auto complete doesnt work in some cases. No tab

wider used setups like wasm-pack. I'd love to try recompiling a full project
with these features, but I just can't find out how to do it.

taking advantage of externref from Rust", but I didn't yet find anything about

I would hope the key presses required to use the native search among opened
tabs had changed.
\- Ctrl-L to go to the address bar
\- release Ctrl (otherwise, the next keypress fail)
\- Shift-6 to type "%" in the address bar
\- space
\- [your query and hit tab/enter to navigate results]
The last bullet is a close to ideal, native search among open tabs and make it
so smooth to find an opened tab among dozens. But the key presses necessary to
get there? Who can use that without weekly hospital stays for finger RSIs?
I love firefox. If someone, somewhere reads this, please please please think
of simpler key presses to use this nice, already built functionality.
(I know non-native extensions provide similar feature. But native would be so
cool and stable, especially that it's already built).

I’ve tried Firefox about once a year for the past five years and always
immediately go back to chromium. Scrolling is always broken out of the box on
all platforms I’ve tried (Linux and macOS).
Edit: trying again, the macOS track pad seems ok but scroll wheel behavior is
different. Firefox requires 2-3 times the scrolling distance and transitions
slowly to the final scroll destination. Chrome does not.
Edit 2: I’m almost positive it’s smooth scrolling. Some people hate it and
some like it. This reddit thread sums up:
[https://www.reddit.com/r/firefox/comments/5zoa1t/do_you_use_...](https://www.reddit.com/r/firefox/comments/5zoa1t/do_you_use_smooth_scrolling/)
~~~
confounded
Never encountered this, same platforms. What do you mean by broken?
~~~
marcrosoft
If I were to guess I think it has something to do with “smooth scrolling”. The
behavior is scroll the mouse wheel three clicks/times to move the page.
Expected behavior is move the wheel at all and the page moves.
Also on a track pad the page should move in sync with your fingers. It doesn’t
in Firefox.
~~~
acdha
That’s what happens on a clean install on Windows or MacOS. You might want to
reset any custom settings and remove any extensions to see if it still

Why Slogging and Schlepping Are Key Startup Values - sk2code
http://www.fastcompany.com/3006142/paul-graham-and-buster-benson-why-slogging-and-schlepping-are-key-startup-values
======
jeremyjh
One pattern that has held-back my personal side-projects from ever achieving
any real value (other than my own education) is that I'm always finding ways
to drop back of schlepping and back into experimentation and analysis. Knowing
this tendency in myself has held me back from any serious contemplation of
actually quitting my job to start a business; I can schlep with the best when
the goal is in sight and preferably there is a gun to my head (like an insane
deadline I've signed up for). But I don't know how to do it when the value of
the work is questionable, or so far down the road that I can't really see it
from where I am now. I'm constantly plagued with "what if no one ever wants to
use this?"
~~~
RyanZAG
Great point. From what I've read and experienced, you're right on the money:
there is a very good chance no one ever wants to use it.
Don't let this paralyze you though - it's why the idea of an MVP and
Kickstarter are so popular right now. The best advice I've heard on this
topic: just give it the best shot you can, fail fast if it doesn't get
traction, and try to learn as much as possible from failing so that your next
project is less likely to fail.
This gives you a really great deadline too: MPV in 2 months, fail if no
traction in 6 months (or even faster?).
Alternatively, if you really don't like the above idea or you can't build your
idea into an MPV in a couple months, stick with your current job and work on
your product on the side. This let's you take as long as you need to make the
product, removes the pressure of starving, and can turn into an enjoyable
hobby even if you don't get much traction.

shawnreilly
Paul's original article (linked by aegiso) is awesome, and I couldn’t agree
more. When I did my first Startup (that failed) I was trying to do something
that was Fun. After experiencing failure and learning my lesson(s), I realized
that Fun is not necessarily the best focus to build a business. My second
attempt (which is where I am now) has a focus on Value, which has been much
more successful. I believe that Value is directly determined by what pain
points you solve, and how many people they affect. In many ways I've had to
train myself to identify the biggest pain points that fall within my
experience/knowledge, and just go for it!! I'm a designer, but as a technical
co-founder, I put a strong emphasis on Product Vision, Business Models, and
solving Big Problems. The bottom line, anything is possible. We just have to
identify what needs to be built, and build it! I'm learning how to code, but
I've realized that team work makes the dream work. So right now my goal is to
build a few strong founding teams for a few of my highly ambitious ideas. I am
experimenting with a new concept (a team building exercise) that shares
similarities with some of the new ‘Studio Startup’ models people are using. I
will be essentially 'CrowdFounding' the Projects, open to anyone that can
execute. Hopefully I can succeed and solve some of these huge problems I've
identified (mostly related to Infrastructure and Security)
------
arbuge
Quite so. I'm thinking that the whole lean startup movement in some ways
exacerbates the schlep blindness problem PG refers to. If you expect instant
rewards/feedback/traction before discarding an idea, you might sometimes be
overlooking something.
~~~
thebear
Good point. I've always felt uncomfortable with the lean startup mantra "If
it's not working out, pivot." If something's not working out, it could be for
one of two reasons: either you're doing the wrong thing, or what you're doing
needs more time and hard work, that is, you just met the schlep. Deciding
which one of the two you're looking at is incredibly hard. I don't think that
there are any rules. The pivoting mantra just kinda glosses over that whole
problem. The best advice I could distil from it would be, "If it's not working
out, don't cling to it at all cost, consider pivoting." Ok.
~~~
mdda
IMHO, this isn't really what the Lean Startup mantra is all about. Lean-wise,
one is really trying to see where there is customer/product fit. When there
is, it's like finding a filter's resonance point : Suddenly you've found
people's hot buttons.
[ no, no, meh, hmm, YESYESYES, hmm, meh, no, no]
The key to the Lean part is only doing a schlep when you've identified that
it'll pay off once done. Don't schlep until you've got evidence that the
destination will be worth the trip.
~~~
thebear
_Don't schlep until you've got evidence that the destination will be worth the
trip._
I see what you're saying. I just think that this leaves unresolved the one
crucial question: what constitutes "evidence that the destination will be
worth the trip?"

Why Elephants Don’t Explode: How Nature Solves Bigness - aaossa

This reminds me of an old (1928) piece titled "On Being The Right Size" by JBS
Haldane [0], which lightly touches on many different concerns related to
sizing:
> Of course tall land animals have other difficulties. They have to pump their
> blood to greater heights than a man, and, therefore, require a larger blood
> pressure and tougher blood-vessels. A great many men die from burst

I'm confused by the slider task. The explanation simply says that voles eat
much more than elephants _per unit of body mass_ , but the sliders suggest
that voles literally eat more food per day than elephants.

animals next to them?

This article is interesting, but all it talks about is why big animals have a
lower metabolic rate than small ones. I wish it would have also addressed the
question of why small animals have a higher metabolic rate than big ones. If
elephants can get away with having such a low metabolic rate, why can't voles?
~~~
ufmace
That's what the article is all about. It's temperature management. Smaller
warm-blooded animals have less mass to generate heat and higher surface area
to volume ratio to dissipate it faster. They need a much higher metabolic rate
to maintain body temperature, especially when the environment is very cold.
They would freeze if they had the same rate as the elephant.
Large warm-blooded animals have more mass generating more heat and less
surface area to dissipate it. They need a much lower rate or they would
overheat. Not to mention the objectively huge amount of food and air
circulation that would be required to maintain that rate.
If either animal had the other's metabolic rate, it would be dead within
hours, if not minutes.

Couldn't smaller animals just evolve better insulation instead? Surely it
would be easier to survive if they didn't have to eat so much.

This is not a startup, and there's no business here. Its a "scratching an itch" weekend project. I'm a link junkie, and like to save big collections of stuff - be it travel info for an upcoming trip, funny gifs, or whatehaveyou. There's no social, and no discovery.<p>I just wanted a super simple, very flexible, lightweight link index. I also wanted to play around with Bootstrap and JQuery.<p>Originally, I built LinkThing on the Twitter API. It used twitter Oauth, and did some neat stuff, like index links in your tweets. But - I don't feel like figuring out how to comply with the new API guidelines, so I've backed it all out, and have built a standalone user account system, and there you go.<p>LinkThing is missing several things:
1. Don't lose your password. The password reset thing referenced in the "join" form doesn't actually exist yet.
2. Links that you add aren't currently editable; but that's almost there. Note: You <i>can</i> delete them.
3. There's some real low-hanging fruit missing, like a bookmarklet, that I'll get too shortly as well.<p>Anyhow, I posted a note about this in another thread some time ago, and wanted to share an update. As noted, this is a weekend warrior / fun project, so don't hold back - I haven't quit my day job for this. Its been fun to develop, and I've actually ended up being a pretty devoted user of it, at home and at work, and it would be cool if some other people found it useful too.<p>I wrote a brief into blurb here that will give you some flavor:<p>http://linkthing.co/doc_getting_started.php<p>Feedback/comments/complaints are appreciated.

Signed up, I like the simplicity of the thing (no discovery/social is a plus
for me). Some thoughts:
1\. You don't ask for confirmation for "dangerous" things: When deleting a
link - I was expecting to be able to fish it out back from some kind of Trash,
or perhaps have a temporary "Undo" option). When clearing the account, again
it apparently didn't ask me for confirmation (I didn't have any links at the
moment, in case you only ask if there's data in it).
2\. On a site such as this, I'd love to have an export option, in case I ever
want to leave (or you need to shut down). It could be as simple as just
producing a plain HTML with the bookmarks.
3\. When you click on a link, it opens a new window to go to it. Fair enough.
But the click count isn't incremented in the existing page (obviously, a minor
nitpick).
4\. Bookmarklet for bookmarking pages directly would be nice. Here's a shot at
it here: [http://dobarkod.hr-test.s3.amazonaws.com/tmp/linkthingco-
boo...](http://dobarkod.hr-test.s3.amazonaws.com/tmp/linkthingco-
bookmarklet.html) (drag to bookmarks bar to save). Ideally, it'd redirect to
the linkthing.co afterwards.

Hey! Thank-you for trying it out, and for your feedback. 1\. I hear you on the
confirmation for Dangerous actions point... I've almost seriously screwed
myself on the Delete Account Data one. That's definitely on my to-do list. 2\.
Export - also agreed. What kind of format would be useful? CSV, or an XML
schema of some kind? 3\. Good catch on the click counter - I'll have to think
through that one - perhaps just a cosmetic non-ajax increment. 4\. Thank-you
very much - That's exactly what I was thinking; I'll steal that code (thank-
you!) and implement tonight, and will post back here.
Thanks again for trying it out and sharing your insightful feedback - its
appreciated!

I think any textual representation of the links would be good - possibly a
HTML file with the links themselves might be the easiest option.
Regarding the counter, yeah, I'd just "cheat" and increment it locally, no
need to go back to the server for it (after all, you know it was exactly one
click).
Also, to add: Thanks for a nice service, well done!
I'll try to use it for a couple of days and see if it sticks (I'm notoriously
bad at bookmarking, or rather, revisiting bookmarks).

Hey - just a quick note - As per your suggestion, I've added an export feature

This is not a startup, and there's no business here. Its a "scratching an
itch" weekend project. I'm a link junkie, and like to save big collections of
stuff - be it travel info for an upcoming trip, funny gifs, or whatehaveyou.
There's no social, and no discovery.
I just wanted a super simple, very flexible, lightweight link index. I also
wanted to play around with Bootstrap and JQuery.
Originally, I built LinkThing on the Twitter API. It used twitter Oauth, and
did some neat stuff, like index links in your tweets. But - I don't feel like
figuring out how to comply with the new API guidelines, so I've backed it all
out, and have built a standalone user account system, and there you go.
LinkThing is missing several things: 1\. Don't lose your password. The
password reset thing referenced in the "join" form doesn't actually exist yet.
2\. Links that you add aren't currently editable; but that's almost there.
Note: You _can_ delete them. 3\. There's some real low-hanging fruit missing,
like a bookmarklet, that I'll get too shortly as well.
Anyhow, I posted a note about this in another thread some time ago, and wanted
to share an update. As noted, this is a weekend warrior / fun project, so
don't hold back - I haven't quit my day job for this. Its been fun to develop,
and I've actually ended up being a pretty devoted user of it, at home and at
work, and it would be cool if some other people found it useful too.
I wrote a brief into blurb here that will give you some flavor:

Scientist quits antimissile panel, saying task is impossible (1985) - Thimothy
http://www.nytimes.com/1985/07/12/world/scientist-quits-antimissile-panel-saying-task-is-impossible.html
======
dogma1138
Things have surely changes in 30 years, because effective missile defense is a
reality these days.
That said SDI wasn't a failure, the "Star Wars" part of it kinda was, but
sensor, targeting solutions, ABM (heck one of the original SDI systems - ERIS
is quite functional to this day) technologies serve as the base for the US's
current missile defense shield and they do work.
SDI also lead to quite a few significant developments in both chemical and
more importantly solid state laser.
Hubble also owes a large debt to SDI, there have been several experiments
regarding bouncing ground based lasers of mirrors in space in which they've
actually launched mirrors and bounced a laser over 1 or more of them. Both the
mirror manufacturing technology and more importantly the ground breaking
tracking and stabilization technology which allowed them to bounce of a laser
of a freaking tiny mirror in space were used in the HST.
~~~
rlucas
Can you elaborate on or source your claim about ERIS?
I'm genuinely interested in the historical and scientific question of the
viability of ABM at scale. I enjoyed a course perhaps 15 years ago with a
professor who asserted that the challenge was intractable due to the limits of
physics. Yet, I have also heard from a former aerospace engineer on the
Patriot system that such objections are poppycock.
ERIS was not in the matters we studied, though THAAD and the then-recent
midcourse interceptor tests were.
~~~
dogma1138
Apperantly ERIS (Exoatmospheric Reentry-vehicle Interceptor Subsystem) wasn't
deployed directly but transferred into THAAD and GMD.
[http://astronautix.com/lvs/eris.htm](http://astronautix.com/lvs/eris.htm)
Scale is a different question, it's a matter of number of interceptors vs
number of threats.
Iron Dome and it's evolution Stunner/David's Sling(used the Radar, tracking
and core interceptor form ID with an added booster stage) are quite capable of
handling large salvos.
HAMAS attempted to saturate the Iron Dome missile defense shield with large
salvos of 30-60 launches but the system still continued to operate with a very
good success rate.
Now Iron Dome has an advantage over systems that would presumably be employed
to counter mainly nuclear threats as it can ignore targets that will not
directly hit populated areas which would be somewhat harder to ignore when
nukes are in play. Any leakage of munitions is also not as huge of a threat as
with nuclear warheads, but losing 2 cities instead of 40 is still worth every
penny if it ever will come to a nuclear exchange, and with a rogue actor /
single launch all of your interceptors can focus on a single target which
gives you very good leakage protection.
From my experience what scientists often miss is that a system doesn't have to
be 100% effective, and you also can have multiple systems (which is the
current doctrine, early/co-stage interception, exo-atmospheric interception,
terminal stage interception, near target interception etc.) and depending on
your target hit success rate use multiple interceptors.
Missile defense is very real, systems like Iron Dome are bigger technological
advancement than things like GMD they can intercept a target as small as a
mortar shell in under 30 seconds which one would never thought would've been
possible even 10 years ago.
However considering that 15 years ago systems like Arrow (2) and Agies/SM-3
were already in advance testing or already deployed with quite a successful
track record I'm not sure why a professor would argue that physics make it
impossible, It was never a question of physics to some extent more about
sensors, software, and the ability to actually terminally guide interceptors
well enough to hit anything, but even during the years of SDI some branches of
the program had successful intercepts.

Of course, we now know that the Reagan Administration knew that the "Star
Wars" anti-missile systems were not going to actually work. The goal was never
for them to work as advertised. The goal was to convince the USSR that they
would work, and force the USSR to spend huge amounts of money trying to keep
up. And it worked.
~~~
akiselev
Do you have any reading materials about the effects the SDI had on the Soviet
aerospace program? The only citations I can find from a cursory search don't
seem particularly reliable or authoritative in this matter (largely off hand
comments by talking heads, even Carl Sagan).
I hear this out economic strategy repeated often as a post-hoc justification
but based on first hand accounts (my maternal grandparents met while working
on the Sputnik rocket and my entire family lived through this period in the
USSR as engineers), my understanding is that although some spending in
defense/aerospace rose during that time, the writing was on the wall for the
USSR and it's space program by the late 70s. According to my grandparents it
was impossible to reconcile the propaganda with what they were experiencing as
engineers actually working in aerospace/defense. Apart from the politically
doomed Buran, there wasn't even any ambition to try and match the United
States except for geopolitical posturing.
~~~
TheCowboy
There were earlier reports of Soviet economic weakness that predate Reagan. As
early as 1975, Senator Moynihan had predicted the demise of the USSR for
economic and ethnic reasons. I think at best the policy accelerated the
process.
My view is that if the Soviet system was inherently inefficient, and it was,
then it should eventually lead to collapse or reform if left to its own
course. It didn't seem to necessitate such an wasteful expenditure that lead
to a collapse that was terribly managed. It's not difficult to imagine worse
scenarios where the Soviet nuclear arsenal played some role.
That said, Reagan's original argument for increased spending was that the
Soviet Union's military capability was relatively stronger.

Sorry, I think I wasn't clear in what I was suggesting with the sentence:
"It's not difficult to imagine worse scenarios where the Soviet nuclear
arsenal played some role."
I meant outcomes such as where a fringe general in the USSR felt it was a
legitimate threat requiring a first strike, or an unmanaged collapse lead to
dissemination and use of nuclear weapons. Basically, a successful policy can
easily become a Pyrrhic victory.
But this is interesting information, thanks for sharing it.

DanielBMarkham
Last week I got through reading "The Dead Hand", which I will plug again.
Great book. I saw and lived these things as a armed forces member and citizen.
It was really cool to finally be able to see behind the scenes.
The most amusing thing about the story of the end of the cold war was SDI.
Reagan, contrary to popular belief, was not a cowboy. His goal was actually to
completely eliminate nuclear missiles, and he told his staff this several
times. Whenever he said this, however, the clique of those in power went
berserko. How could he advocate such a thing! So they most always managed to
shut him down, prevent him from ever going public with his dream.
Gorbachev, likewise, was a prisoner of the system he was in. The armed forces
had a huge -- and mostly secret -- budget. They were into everything. They
were paranoid and highly suspicious of anything having to do with the U.S.
They were more and more detached from reality. For a while there, soviet spies
were instructed to start gathering clues that a surprise nuclear attack was
underway, even though nobody in the west had anything like that in mind. Given
that amount of craziness, Gorbachev's goal was never to end communism, it was
to open things up and try to make the system work better. He genuinely cared
for the little guy, and saw that the system was not working.
Additionally, the Soviets had reached the point where everybody in the system
(mostly) knew how messed up it was. They just couldn't do anything about it.
People wanted somebody, somehow to fix things.
During a meeting with a physicist, Reagan first heard the idea of a missile
defense. He latched on to it right away, although it took many months to go
public. What better way to eliminate nuclear weapons than to make them
obsolete? It wouldn't be offensive, it would be something to prevent damage.
Who could oppose that?
Now the funny part is that even though this was mostly just an idea in
Reagan's head, it drove the Soviet's crazy. How much work had been done? Did
the Americans have a working weapon? What technologies should we develop? The
natural Russian paranoia and distrust of the U.S. fed into what was just a
dream on the American side. (Yes, I understand that money was spent, but SDI
was something that was going to take decades. Initial progress was extremely
slow.)
So the Soviet armed forces spent all kinds of resources pouring over SDI and
trying to come up with a response. What did they fear? Space-based nuclear
weapons and nuclear-powered space-based lasers, not SDI itself. Finally they
came up with their own plan to create their own SDI -- a hugely expensive
program. After all, how could you plan to counter something that doesn't
currently exist? When the Soviet government looked at those projected
expenses, along with the failing economy, the lost war in Afghanistan, and
many other factors? It was obvious that something had to change.
It's a fascinating story because although the system on the U.S. side could
certainly shut down the president from doing something so radical as proposing
an elimination of nuclear weapons, what could they do about the guy just
having a dream? He had an idea. People have ideas. Nobody really knew how to
stop him from talking about his ideas. But the idea alone, whether it worked
or not, was just another straw on the camel's back that eventually brought
down a huge system of governance. Amazing story.

My anecdotally informed opinion is that Soviet science advisors thought the
Space Shuttle was key to making SDI work.

Indeed, passion (at a macro-level) is important. But even within your passion
lies a long list of tactical things that need to be selected from.
The challenge is limited resources. You can't do everything (regardless of

your time and energy.

Ask HN: What tips or tricks do you use for fast and efficient note taking? - mtrpcic
I often find myself wanting to document various pieces of information during meetings or my commute, but often the information is coming at me faster than I can put it all on paper. I end up getting flustered and the quality of my printing degrades as I try to scrawl everything down. What shorthands, tips, tricks, or other note-taking quirks do you use to make your life easier?
======
aethertap
I tend to use notes as a self-test rather than for logging what's been said.
For example, as I hear something important, I'll write a small question to the
effect of "what is X?" or even just "X?"
Then (this is the important part) _soon_ after the note-taking session is
done, I go back and answer all my questions from memory, in writing. That lets
me get tons of stuff down on paper later at a slower pace, and it also helps
to cement the stuff in my mind because I'm not distracted by trying to write
it all down while it's happening. Forcing myself to recall it also does a lot
to make it stick.
Usually I can use my questions as cues to go look up the stuff I forget, and
if there's something that I know I'll forget and won't be able to look up,
I'll try to write that down (that's pretty rare though).
~~~
maraglee
Yes! The most valuable information is usually not the pure content but rather
things that deviate from that. So contextual information, relationships
between things, knowing what's important (the gist) and what's unclear.
Especially the last part tends to be what at the end of the day gives new
insights

KhalPanda
> ...coming at me faster than I can put it all on paper
So don't. :-)
I don't know if 'paper' was a figure-of-speech to mean 'some recorded format',
but if it was, get yourself a cheap Chromebook. I (and I expect most) can type
a lot faster than they can write, so that's step one.
Step two is to just work on making your notes as brief and concise whilst
still being intelligible to _you_. Unless whatever somebody is saying is
extremely densely packed with critical information, there is a lot of filler
you easily can cut out.
For example, if someone read your post to me, all I would write is:

Ask HN: How did you implement Authorisation/Access Control for your SaaS product - devj
I have been tasked to implement access control in a multi-tenant SaaS product. Would be really helpful if you can share your experiences in implementing RBAC/ABAC/etc and also point to relevant articles or OSS projects to understand it better.
======
twunde
There are a couple of components that make up Auth.
* Authorization - How do I confirm who this person is?
* Identity - Everything about the person. Think name, email, address, tenant_id
* Permissions/roles - What can this person do?
I'm going to discuss this with the assumption that you're using some sort of
relational database. If you're using something else, you should be able to
adjust accordingly. Keep in mind that your web framework probably has
libraries for all of these and standard practices since every app that
requires you to sign in had this..
Let's start off with roles and permissions. Typically, most companies will
want at a minimum an admin user and a regular user. This usually ends up
expanding to include specialized roles such as accounting, who would only have
access to billing information, auditor, which would be a read-only role.
Identity - Unless you're just starting a project, this has probably been
implemented already and may be called users, customers or employees. This can
be one table or a set of tables and would include the relevant information
about the person logging into your system. At the very least this includes
name, email, and tenant_id.
Authorization - Typically this will start out with username/password login
combinations, but is often expanded to include 2FA-login flows, single sign on
(OAuth flows using SAML or Active Directory/LDAP authentication). That there
can be multiple auth workflows is a good reason to keep these as separate
tables from your user table(s).
A good open-source example is Discourse
([https://github.com/discourse/discourse](https://github.com/discourse/discourse)).
It's a good case because it does have SSO options

Trade in your iPad, get a $200 gift card - kapkapkap

======
t0
Their recycler ([http://cexchange.com/](http://cexchange.com/)) will resell
the iPads to cover the $200 loss, which will actually create more competition
for surface. This isn't too brilliant of a strategy.
~~~
eupharis
Presumably this trade-in will be done by people who are thinking, "I'm not
crazy about my iPad. I want to try something new." If Microsoft convinces
these customers to try Surface versus something else (aka Android), it's a
win.
The iPads will be resold to someone thinking, "I want to try a tablet, but
I've never tried an iPad." Which is a different market segment.
Also, a $200 gift card != $200 cash. Some estimates say 20% of gift cards in
the US are not redeemed. See:
[http://en.wikipedia.org/wiki/Gift_card#Redemption_rate](http://en.wikipedia.org/wiki/Gift_card#Redemption_rate)
And even for the cards that are redeemed, Microsoft is making a profit off
every $ that is spent. Plus interest on any gift card balance.
It's not far-fetched to imagine Microsoft making 30%+ profit off this, while
increasing the (dismal) market share of Surface devices.

sspiff
Or a person thinking "I want a cheap iPad for the kids", but either way, those
people are less likely to buy a Surface, so your argument makes sense.

was clueless enough to load it with 40G of software.
~~~
TheAnimus
I feel sometimes as if I'm alone for liking my Surface RT.
8.1 for outlook was the real clincher. Before I hadn't really _liked_ any
tablets I'd used.
But now this thing really does go everywhere. Office is rather integral to my
workflow, every alternative I've tried hasn't cut the mustard. Now when I'm
away, I've got my laptop and my 'office slab'. The touch cover actually works
rather well, I won't mind typing out a good long email on it without wanting
to slam the device into the wall (which my Nexus 7 makes me want to do).
It is also remarkably adept at just working with anything I slam on the USB. I
can use it to backup my SD cards to a USB HDD when travelling (having lost an
SD card last year half way through my holiday I'm paranoid!) or I just plug in
my USB headset for Skype. It can browse the web including pages that have bad
touch events (ie menu comes down on mouse over, not mouse down).
And it does flash.
I've only got an iPad 2 to compare against for speed, and yes whilst I'd like
it faster, it isn't problematic.
I can't really see a lot of the hate on the Surface, as a product it isn't
really there yet. But neither is my iPad or my Nexus.
~~~
reginaldjcooper
That's awesome, I'm glad you like it. Now that you mention it, I recall
thinking of the keyboard cover as a great idea.
I guess many things you list are orthogonal to what I would want it for (and I
am quite pleased that there's no more Flash), so I don't see it as an
improvement to the iPad, nor is it any more open.

ryankshaw
Some time ago I saw something that Microsoft gets $15 for every android device
sold while google gets 0 (because of patent extortion). It would be pretty
funny to see something now that says "Microsoft makes more in Q4 off iPad re-
sales than from surface sales" note: I'm saying profit, not revenue, because
of how much they have to subsidize surfaces thus making negative profit while
at the same time re-selling the ipads they got for $200 at market rates, thus
making a profit.

I bought an iPad 2 last summer for $200. This honestly isn't a bad way to get
rid of it, except my biggest issue with getting a Surface at this point is my
unfamiliarity with the Windows platform -- I'm not saying I wouldn't be able
to use the thing, it's just that there would be a subconscious effort being
made that I don't really feel like dealing with (at least.)
Still, I think having $200 to spend on Microsoft stuff isn't a bad trade.
Office is expensive.

ScottWhigham
Weird. I just sold an iPad2 on ebay last month for $300. Looking at eBay, that
is the current going price for a used iPad 2 in good condition (as mine was).

consumers.

In comparison: Gazelle offers $175 for an iPad 2 WIFI-only 32GB (Microsoft

desktop OS (with touch screen functions or not) on a tablet, they want a
tablet OS - like iOS.

It really seems like Apple left early iPad adopters out in the cold. Last

iPad 1 had a _very_ decent lifespan compared to the tablets released by
competing manufacturers shortly afterwards.

>> iPad 1 had a very decent lifespan
I beg to differ. I assumed that I would get 3 years out of my iPad 1 but
barely got two.
I made the wrong bet by placing blind trust into Apple when I paid extra for
the 64GB version to ensure that it was 'future proof'. Sadly, by the time I
upgraded to iOS 5.x, the iPad became slow as molasses and the browser would
crash every 5-10 minutes.
Don't even get me started on how iOS 6.x has turned my iPhone 4 into a pig.
I'd be a hell of a lot happier if Apple would let you easily downgrade the
OS'es of their mobile devices.

Really? I still have my iPad 1. Browsing HN on it as we speak. It's running
iOS 5. The only downside is that the percentage of apps I can install is
diminishing rapidly. Still, I bought it primarily to consume media: audio,
video and books. And I reckon I have at least one more year before I would
feel compelled to upgrade.

If yours doesn't crash all the time because WebKit runs out of memory, then
you're luckier than me (and a few people on the Apple forums). For me, the
usable lifespan ended with the introduction of iOS 5 (my friend's iPad on 4.3
is much more stable).

Former Google exec, Android founder accused of having a 'sex ring' in complaint - CPLX
https://www.usatoday.com/story/tech/talkingtech/2019/07/02/android-creator-andy-rubin-accused-having-sex-ring-ex-wife/1634963001/
======

"Sex ring"? What does that even mean? A company exec liked sex, was likely
unfaithful towards his wife and was also likely violating company policy by
having sex with subordinates. Why should this matter to anyone beyond his wife
and his employer? It's nobody else's business.
~~~
privateSFacct
Let's be clear around the allegations.
Three days before getting married and two weeks before she was going to give
birth to his child he asked her to sign a pre-nup. He suggested she use an
"independent" lawyer - and recommended the same attorney who had represented
HIM in previous divorce proceedings. They then allegedly didn't disclose all
his assets (so the decision to waive an interest would be informed) and her
attorney they claim was actually working for Rubin and knew of the fact that
he had a history of cheating and a bunch of other stuff given his past work on
the divorce much less how much the attorney might value his relationship with
Rubin (rich guy / senior at google). No conflict waiver was even prepared or
signed.
The sex ring claims come from the allegation that Rubin procured the services
of women to have sex with other men.
Plenty of other unpleasant claims.
This all in the context of a marriage where he has made promises to someone.
As to who might mind or be interested?
The employees he supervised might mind - especially since he allegedly
pressured them into sexual relationships while simultaneously having lots of
other sex. Crappy work environment and disease risks.
The public might mind. A poor black guy running a sex ring might end up in
significant criminal trouble. A white guy working for google get's paid $80
million by google and no chance of criminal action.
These tech execs are masters of the universe in their areas. The tone at the
top of a company absolutely filters down into their product approach and
adherence to an ethical framework. Look at decisions around user controls in
Android under Andy (terrible) vs iPhone (better). Are these necessarily
linked? Maybe not - but you do tend to see a tone filter through a crazy
number of places in various ways. So the public might like to know if the
folks running the show are total amoral bastards.
The list goes on.
I hope she takes him to the cleaners.
Additional public interest in these situations is the special casing for these
guys - behavior that no one else could get away with.

version of what happened.

Ask HN: Does this software exist? - ScottWhigham
As a musician on the side, I've come across a "problem" that I'm hoping someone can help me solve. Here's the "problem":<p>* I have a group of songs that I play (let's say 50) that is a fairly static list<p>* I want to be able to plan out set lists based on those songs for various gigs and then print out the set lists in advance<p>Right now, I'm using a kludgey combination of Excel and Word (Windows guy, but I do have a MBP). It sucks - I make the list of songs in Excel, then I create a separate document for each night (and copy/paste the songs in).<p>Ideally there's a piece of software that lets me drag and drop the song onto a "view" (or whatever) that I can save/retrieve/print. I'm just trying to simplify the process of creating a set list. Sure, I could create it but it seems like this should exist already (but I can't find it).<p>Any ideas?
======

Maybe some of the software used for "setlists" for worship songs in Church
services would help? You can do things like print lyrics with chords, "song
books" and such; a basic feature is preparing a list of songs for the expected
running order.
Only ones I know of (from research a few years ago on FOSS apps for this)
<http://opensong.org/d/about>, <http://www.easyslides.com/index.php/features>,
<http://openlp.org/en/features>, <http://www.lyricue.org/>.
There are very mature paid apps for this sort of thing too.
HTH.

dmlorenzetti
You could use TeX or LaTeX. Create an individual file for each song,
containing whatever information you want to print for it. Presumably there are
music-oriented LaTeX extensions that can pretty-print the lines and clefs or
whatever (not a musician, so I don't know what, exactly, a set list should
look like).
Then your play list for each night consists of a sequence of songs you want to
play:
\input songs/stairway-to-heaven.tex
\input songs/take-me-out-to-the-ballgame.tex
\input songs/venus-in-furs.tex
As you get more sophisticated, or as your needs grow, you can define macros
that control what gets printed, or how.
~~~
batista
How is this better than doing it in Excel with copy/paste as he does now?
What benefit does LaTeX bring, so that he has to install some hundreds of mbs
of a TeX distro and learn the basics to work in it? Does he need elaborate
math symbols or fine grained typography for a set list?

The iTunes playlist thing makes me think of another option: creating a
"Contact" for each song title in a contact mgmt app, and then creating a
"Group"/"Category" for each set and adding that contact to that group. It's
the same thing - just a different twist on how to think about it.

ChuckMcM
Lets say you have all of these songs on your iPod, you can create a 'playlist'
and then print that out in iTunes. I used to do that with MusicMatch when I
made a CD for the road, burn the playlist to the CD and print the playlist for
the label.
~~~
ScottWhigham
Yeah, Playlist is exactly what I'm talking about. I didn't know you could
print a playlist.
------
batista
You could create an iTunes playlist with your songs.
1) Create a playlist with all the songs.
2) Right click on it, and click "duplicate".
3) Drag the songs to the order you want. Remove any songs you don't want in
this set.
4) From the menu, go "File -> Print" and select song list.
Repeat steps 2 to 3 as many times you want. You can also rename the set
playlist, to reflect the set name (e.g "2012-22-09").
Alternatively: you could also use some "todo management" style software to
print lists of things (in your case, song names) that you can re-arrange.
Bento might also be an option.
~~~
ScottWhigham
That's great - thank you. The iTunes playlist option will be "good enough" for
my purposes. It's a hacky way to do it but at least I'll have a reason to use
iTunes for something other than backing up/configuring my phone haha.

How Space Cadet pinball won the Windows desktop - davidst

Anyone know the story behind Hover!
Including something like that on the Windows 95 CD was an odd decision. Sure,
on one hand it shows Windows 95 can do 3D graphics/games, but it was such a
terrible game and the performance was so terrible, it just added fuel to
'Windows sucks for games' fire.

I am very thankful for Hover and Pinball. They made me want a faster and less
buggy computer. This resulted in wonderful mishaps -- deleting Win system
files, recovering into Vector Linux, trying Win 3.11 for WG, and finally
ending up in Win98 SE. All the in between is free knowledge. All due to Hover
running at 3FPS on my Cirrus Logic onboard gpu/100mhz cpu.
In my heart, the reason for Hover -- to plant a seed forging low level
algorithm programmers.

Ask HN: Why are FOSS projects beginner unfriendly? - thewhitetulip
I have been in the FOSS community since a few years now and projects either lack documentation or they don't actually support new comers to the projects. I faced an issue recently about docs too, it seems like big projects do not care about total newcomers, why is it so?
======
dvhh
As it is for even closed source project, documentation and support are a major
pain, and are not as rewarding as aligning correct lines of codes.
I will try to use a gross misrepresentation of a new-comer, but chances are
they will ask trivial question that do not concern the project ( or are
already answered ), some resources ( developer time ) will be used in favor of
answering/guiding the newcomer ( who probably did not have search the usual
sources before asking the question ).
Documentation is quite a pain to maintain, as it requires a good grasp of the
English language ( mostly ), and quite a lot of empathy to figure out who the
documentation is for. Additionally you have to make sure the documentation is
accurate as the software change.
Returning the question: do you accurately comment the code you write for fun ?
~~~
thewhitetulip
>do you accurately comment the code you write for fun
Mostly, yes. But not when I am learning stuff, for eg,
[http://github.com/thewhitetulip/Tasks](http://github.com/thewhitetulip/Tasks)
is a small app I built, there are next to no comments there because I was
learning the language and thus didn't write much comments there.
I understand docs are pain to maintain, but a good FOSS project which is
coding related (like a code library) is an amalgamation of the code AND the
docs. The first preference goes to the lib with a great documentation.
>not as rewarding as aligning correct lines of codes
Yes, but when we look at the reward incorrectly! Yes, nobody will hail your
contribution, but the fact that the project will be hailed because of the docs
is not thought about mostly.
>but chances are they will ask trivial question that do not concern the
project
This might not be a gross misrepresentation, but yes, sometimes there will be
audience who doesn't fit in your project's audience, but what about the
audience who fits?
I recently started learning a front end framework, I am totally new to a front
end framework, I do not like frameworks, I learned and wrote a book on Go
without using framework ([https://github.com/thewhitetulip/web-dev-golang-
anti-textboo...](https://github.com/thewhitetulip/web-dev-golang-anti-
textbook/)).
The docs are awesome of the project, I mean it. They teach the basics of the
framework but _not_ how to use it in an actual project. Yes, if I know how to
bind a variable via the docs it is great, but I do not know how to build a
single page app just by reading how to bind a variable. It is a pre-requisite
though.
For a framework which wants to be the top framework, I feel that there needs
to be docs not just about the APIs but also about how to use it in a real
project.
P.S: In the past, while commenting partially negatively about something, a
person had taken huge efforts to crawl back on my HN/reddit comment history
and calling out the names, I am intentionally leaving the name out of the
comment; This is a general thing across all projects, not just the one I am
complaining about.

Why Users Abandon Forms with Select Menus - antimid
http://uxmovement.com/forms/why-users-abandon-forms-with-select-menus/
======
kileywm
The article suggests radio buttons instead of most select menus.
I can appreciate the ease with which one can skim radio buttons vs select
options; however, once there are more than a few options, the sprawl of radio
buttons can be a little ridiculous.
The screen space required to display 50 states via radio buttons vs select
menu is tremendous. At that point, I suspect it would be difficult to
determine where the list of radio options end and the next form field begins.
~~~
navait
Zip code is usually a better way if it's relevant - you can fill in the
state/town automatically.
Obviously, there are situations where that would not apply.
~~~
eric_the_read
Even with ZIP codes, they don't always map to a single state.
[http://gis.stackexchange.com/a/167333](http://gis.stackexchange.com/a/167333)

More users start forms than finish them
Imagine if the opposite happened!
~~~
coldtea
What's so special about the opposite? It can easily be achieved.
10 users start 10 forms each, but leave them incomplete.
100 other users then finish one each of those forms.
So you have 10 users starting 100 forms and 100 users finishing said 100
forms, thus "more users finishing forms than users starting them".
~~~
mwfunk
Well, call me crazy, but I'm going to go out on a limb here and postulate that
in the context of this discussion, the people finishing the forms are presumed
to be the same people who started them. You could probably also find loopholes
if you take into account things like time travel paradoxes but I'm not sure if
it really adds anything. :)
~~~
coldtea
Yeah, mostly tongue in cheek response.
------
CamperBob2
One common reason is if your form contains multiple
select menus. Research shows that forms with select
menus often get abandoned. This is because they take
more time and effort to complete.
No, actually, in my case at least, it's because they often don't include the
option that applies to my situation. When that happens (and there's no 'Other'
selection option) I'll either pick something at random, or abandon the form.
------
molecule
This strikes me as somewhat of a mish-mash:
\- It predominantly addresses the lowest-common-denominator subset of users:
beginning / un-savvy users who are using a site / its forms for the first
time, but the article attempts to make a point by referencing behaviors of
familiar, advanced users: navigating a form's fields using the keyboard: _Most
forms begin with text fields where users type in their input. But when a
select menu appears, they have to move their hands from keyboard to mouse to
select an option. This interrupts their typing flow and slows them down._
\- Discourages the use of select menus because they are 'hard to read' and
require 'dexterous mouse maneuvering', but both of these can be mitigated via
CSS.
The article has good points and has some good recommendations and is useful
for its target use case, but the absolutist prescription, 'The Only Time to
Use a Select Menu', seems to only address a specific case: using a form on an
unfamiliar site for the first time, which would be fine for the article if
were stated as such. However, there are many times when a select menu is
appropriate: familiar users who use a site multiple times, when available
space and / or menu population precludes the use of radio buttons, etc.
------
ramanathanrv
The article is postulating only a theory. We have seen the opposite true in
credit card forms where users have to input card expiry date. No matter what
sort of formatting we did, users always typed expiry wrong and our JS would
point it out. We finally had to abandon input text boxes in favor of select
boxes for card expiry month & year. We measured the eventual success rate and
that turned out to be higher as well.
My guess is that since the scope is so narrow (1 out of 12 choices for month)
and selection is very obvious, perhaps people made lesser mistakes here.
Select boxes are more effective in mobiles as typing takes more effort than
tapping.
~~~
blacksmith_tb
This is something that is badly implemented on many, many checkout forms,
partly due to using selects/dropdowns (since they conceal how the choices are
formatted), but mainly because an amazing number of sites seem to think it's
reasonable to offer only January, February, March instead of the 01, 02, 03
that actually appear on all credit cards. This not only stops you from
focusing that element and typing to choose it, but opens up the possibility
the user will choose July for 06, for example.
------
mschuster91
There's another solution: cascaded dropdowns.
One common, nasty example is a list of countries in online shops. Many at
least either pre-fill based on IP geolocation or stick the most common target
countries at the top, but there are also some sites that sort alphabetically,
or worse, group by continent and then sort.
This can be solved by having only one dropdown visible with the continent;
once this is selected, a dropdown with the country appears below, and
optionally a third dropdown for the county/state (e.g. USA, optionally in
Germany but no one requires the state in Germany anyway).
Downside of this approach, though, is that browsers cannot auto-fill.
On a sidenote, I remember that you can "annotate" input HTML elements to ease
auto-fill (besides the obvious type=tel/fax/email). Can anyone please give me
a hint? I seem to be too stupid to find the guide for this again :(
~~~
detaro
I find the multi-dropdown pattern even more annoying. Yes, the individual
choices are smaller, but then I have to click/tab-select the next drop-down
multiple times, wait for fold-out animation, understand what the options are,
repeat, and there often are strange bugs, e.g. if you try to fix an error.
Non-dropdown selects next to each other are better for this pattern IMHO, but
take space.
Searchable dropdowns/autocompleting text fields really should be part of the
HTML standard...
------
agateau
I disagree with the article for two reasons:
1\. Many computer-illiterate users always click to switch from one input to
another, so clicking on a select does not make them much slower
2\. Many users are not aware that the text part of a radio button is actually
clickable and will loose time precisely aiming at the round circle to select
it. And they are unfortunately often right to aim at the circle because of the
many loosely design pages which do not make the text part of a radio button
clickable.
~~~
fibbery
I think that's why they were suggesting to make it a button with a radio
button inside it(?), but that seems kind of wacky to me
------
asimuvPR
Devils advocate here: use select menus to reduce the amount of support tickers

~~~
rubidium
I've seen this before in IT tech support. Invariably there's some drop down
where none of the selections apply to my issue, but it's required to pick one.
I always pick the most dire issue.
------
girzel
Select menus are bad, but multiple select menus are a new level of anti-user
hostility. With single select at least you can use the keyboard; with multiple
select you're in for keyboard-plus-mouse-plus-squinting pain, and a real
possibility of screwing it up and having to start again.
I run a site where user input often takes the form of long select menus. I'm
typically dead against javascript "helpers", but this is a use case that just
screams for ajax and dynamic field munging. I still haven't gotten around to
doing it, though...
------
kazinator
> _But when a select menu appears, they have to move their hands from keyboard

Simply not true. They do not _have_ to; they just don't know that when the
keyboard focus is on the list or combo box, they can go through the selections
using the arrow keys.
But even for those who know the keyboard shortcuts, long lists are annoying,
like long lists of countries (most of which will never produce a paying
customer for that site), or lists of of years starting from 1900.
~~~
CM30
To be honest, that reminds me.
Why do sites use drop down menus for years like that?
I mean, in new browsers (or older ones with Javascript) you can add perfectly
good calendars for things like date of birth, booking date, etc. In other
ones, you can just let them type in the value in some restricted format. Who
honestly cares if someone claims to be 150 years old?
~~~
kazinator
Moreover, if you want to be able to filter out bogus entries, you have to let
users _enter_ bogus info. If you put in too many constraints, you hamstring
your ability to tell bogus from good. For instance if you reject 555-NNNN
phone numbers because 555 is fake, the determined user will enter a more
convincing fake phone number.

Uh, apparently the author didn't notice that on a couple platforms, you can
generally type into a select box and it will act sorta like an autocomplete. I
do this all the time for US state select boxes, I tab into them and press 'T',

Select boxes are for long exclusive lists. I would like to see all the US
states in a radio grouping... Not..

Well, computer users aren't the problem its all the UX "experts" that have
never read a HID document for any major platform (especially desktop ones).
I don't care if grandma once a week has to reach for the mouse to fill in an

of imput devices (particularly keyboard, but frequently desktop touch, or pen
based) because they think they know better and decide to invent some new
paradigm without understanding the existing ones. This is part of my gripe
with much of the last 10 years of windows, which broke a lot functional
paradigms without replacing them with an alternative. Or they 1/2 broke
something.
Take the right click on the task bar to open an applications system menu which
worked from windows 95->vista. That operation now gives one the nearly useless
option to pin the application. Now when a window is offscreen and I need to
move it onscreen, and the app developer broke the alt-space keyboard
combination you have to know that MS changed (and didn't really document it
anywhere) the behavior too the very mac like, shift click. Pretty much the
only place in windows that the mouse buttons have keyboard modifiers. Its like
the guy who wrote it couldn't figure out how to add a "pin to taskbar" option
to the system menu.

The biggest complain I see from users is the Mobile Picker part of the

entirety. An improved picker would be better. I am not really convinced of the
other arguments.
Also, putting items in the menu is some random order is not real helpful.

Cost of Employer-Provided Health Insurance Rises Toward $19k a Year - myroon5

I don't think employers should even offer health insurance.
Leave it to the consumer to buy just like all other insurance. In fact the
increase in wages could be used to fund a basic preventative care plan (read
not full on single payer) for all Americans.
~~~
fragsworth
But as an employer in the U.S., you get to write off medical insurance as an
expense that isn't counted as income for the employee. It's entirely tax free,
and a rational employee will take it into account as part of their
compensation package.
If you don't want employers to give it to employees, then we should fix the
tax situation.
~~~
dangero
You nailed it. When I started my own consulting business I just about fell out
of my chair when my accountant said I couldn’t write off my health coverage. I
pay about $19K a year and that’s after taxes so more like $25K+.

S-Corp greater than 2% ownership. This means I can sort of write it off, but
only after the corporation providing the money through payroll which means
paying tax on it upfront. Doing it that way could end up costing me money
because payroll taxes are higher than corporate dividends.
In general I think the point is, why can corporations just straight write off
premiums for their employees when self-employed types have all these special
rules to follow vs just a standard deduction?
~~~
didgeoridoo
If you're an officer in an S-Corp, you're required to pay yourself a "market
rate" salary for payroll tax purposes, and cannot legally use the salary/draw
distinction as a tax avoidance strategy. If you're not paying yourself a
salary, the IRS gets very annoyed.
If you're a sole proprietor, the tax impact should be equivalent whether you
choose to take draws or salary:
> Sole proprietors and members of partnerships are free to pay themselves — or
> otherwise take the profits out of their businesses — whenever they’d like.
> Payroll withholdings do not apply, but each individual essentially pays the
> equivalent on his or her reported income at tax time.

Paying the health insurance through payroll would be in addition to the fair
and reasonable salary. Say I set a fair and reasonable salary of $65,000, then
I want the S-Corp to cover my health insurance $20,000 a year then I need to
set payroll to $85,000.
Yes, I could continue to pay myself just $65,000, but the IRS could come
knocking and say, "you said you paid for health insurance through S-Corp
payroll, so that means you only gave yourself a $45,000 salary which is not
fair and reasonable.

My view: we need price transparency.
Find out a medical code, call 3 different hospitals in your area and try to
nail them down on a price for that billing code - the variance will be large;
but given they should all have similar price structures and pay wages that are
roughly the same, they shouldn't vary by much more than 5% ...
~~~
cptskippy
Price transparency doesn't really help when you can't factor in all the
potential costs and unknowns. It certainly is of no use when there's a life
threatening emergency.
A birth might be a flat $4000 but what happens if the mother has high blood
pressure and needs to be on a magnesium drip? Or the baby is in distress and
there's an emergency caesarean? Are you going to call around for a better
rate?
The problem with our medical system is insurance. Insurance companies are
always playing games to avoid paying bills and they force medical providers to
play games to get paid. Vast amounts of money are wasted in billing and claims
departments trying to process or deny claims.
It's gotten to the point where an insurer can fine the insured for submitting
a claim with a code that requires prior authorization after seeking care from
a healthcare provider. I'm not sure how pricey transparency would help with
that.
~~~
leifaffles
This is a particularly naive understanding of markets.
To restate your argument: there are sometimes unpredictable health care events
that arise for which one cannot negotiate, bargain, and price compare in
advance. Therefore, price transparency doesn't work.
The problem is you wouldn't make this argument about any other sort of good
(for example, an emergency or home car repair) because you know exactly how
markets function in those cases.
The answer is: when there's price transparency, and consumers are incentivized
to shop around and demand lower prices, prices come down. This benefits not
only yourself, but also consumers who don't want to (or are unable to) perform
this role themselves.
This is why you pay cheap prices at the grocery store even if you don't
haggle, clip coupons, and so on. This is why "emergency" home and car repair
(while it may cost more) does not cost an order of magnitude more than "non-
emergency" home or car repair.
~~~
speedplane
Some reasons why healthcare markets are not nearly as efficient as other well-
functioning markets (like car insurance):
\- Prices are extremely inelastic: You'll pay whatever you have to not die.
\- Consumers have far less control over what they purchase: they are told to
purchase things by doctors, who may have different incentives.
\- Healthcare isn't a "commodity" that can be easily swapped out. Prescription
drugs may be commodities, but doctors are not. People won't easily swap
doctors, making the entire system less efficient.
\- There is no "perfect information", in economics speak: people know very
little about what the quality of care they are receiving.
\- It's extremely expensive to bring healthcare "products" to market (e.g.,
new drugs, hospitals, etc.). Like building a nuclear plant, very high capital
costs reduce the number of players that can enter.

watertom
The only solution is for employers to stop offering healthcare. Give the
equivalent in salary to employees and let the employee figure it out. When
this starts to en masses healthcare will get figured really quickly, i.e.
single payer
The Fortune 1,000 won’t do this because they can control employees, wages and
competition. Getting a small company off the ground is so much harder because
only recent grads are willing to take a job without healthcare. I’ve turned
down a dozen companies because of healthcare issues.
I also find it strange that we discuss guaranteed income as a viable solution
but not guaranteed healthcare.
~~~
pfranz
I know lobbyists are pushing their agenda, but why is nobody talking about the
economic freedom of untethering employment to heathcare? So many people are
tied to less than ideal jobs or prevented from starting their own business
because of insurance. You also constantly hear about companies hiring
contractors or cutting hours just under the margin where they owe benefits.
It's funny that I often hear about how expensive COBRA is and how it's not a
good deal. That's what your employer is paying for your insurance. (in an
ideal world) that is would-be compensation of your's.
I know the actual cost of healthcare isn't pretty, but it does no one favors
by hiding it and tying it to your employer with weird tax incentives.

Bernie Sanders "Medicare for All" plan makes all the sense in the world.
Expand medicare for everyone. Pay the government instead of insurance premium.
Medical costs go down. Doctors/hospitals might earn less, but will have
guaranteed payments. Medicare, a government program, is considered the gold
standard of healthcare, so this isn't the government's first rodeo.

There are simple answers Health Insurance affordability in the US. Rationing.
No NOT via a single payer system where some all-knowing official decides who
does and does not get care. Rather, the rationing is done by the buyer. For
example, Buyer one could decide to only buy a policy which covers only generic
drugs, which would exclude all patented drugs (newer and even superior), Buyer
2 could decide to buy a policy which covers generic drugs and patented drugs
in one or more specialties (e.g., cardiac). The theme is let the buyer decide,
not everyone wants to live the last 10 years of their life struggling to
regain their youth.

Are there examples of such a system working anywhere? It sounds plausible, but
the fact that it didn't arise pre-Obamacare gives me pause. It seems like the
demand for it might not be prevalent enough, or the savings too small.
I'm interested in new models, but I'm tired of the US thinking it has to be
special with its healthcare system and wasting a trillion dollars a year.

wahern
With Kaiser Permanente Northern California, for a family of 4 $18k buys you a
gold plan with $0 deductible, and $20k buys a platinum plan. This is on the
open market. I just priced it on their website. Most plans are substantially
cheaper.
HMOs are really the way to go, but unfortunately Americans stupidly prefer to
pay a huge premium for more choice (or at least one very specific dimension of
choice). A family member who is a long-time partner at a law firm forced her
firm to purchase a plan that allowed her to keep her doctor of 20+ years. This
happened during the nationwide market reconfiguration as the mandates rolled
out and insurers aggressively re-architected their plans and provider
networks. Now she rants and raves about how Obamacare raised the costs of
healthcare, and her partners resent her for forcing the huge premiums on
everybody. She's totally unwilling to consider that the problem was entirely
of her own making; that her firm could be paying a fraction of their current
costs for the same quality of care, just not including that one specific
doctor.
HMOs aren't very common, and in many regions they seem to suck. Fortunately,
Northern California Kaiser is one of the best hospital systems in the nation.
If you live in the Bay Area I highly recommend it. Kaiser aggressively pursues
cost-cutting measures and efficient service delivery procedures. Appointments
go through a phone bank of nurses with a rotating staff doctor, so minor
illnesses like a cold or flu don't require wasting your primary physician's
time. For more serious but still common injuries like a broken wrist you're
directed to, e.g., their sport injury unit clinic; again saving both the ER
and the primary physician's time. Kaiser runs their own labs, and the volume
of people their labs efficiently handle is incredible. All the doctors are
employees (as opposed to independent, affiliated providers like in many for-
profit hospitals), and Kaiser doctors very consistently apply uniform policies
on best practices, prescriptions, etc. I think they're large enough that they
run their own studies; at least that's the sense I get when I've inquired
about why they choose X instead of Y.
All of this comes across to some people as impersonal, but personally I think
it's amazing. I've never had an interaction (nor have any of my family
members, AFAIK) that left me feeling cheated for attention, even though
there's always the sense that everybody--doctors, nurses, staff--is working to
keep things moving along at a brisk pace. The way they've balanced conflicting
requirements is really laudable. After being with Kaiser for many years, other
hospital systems seem downright chaotic.

It genuinely blows my mind that some of the top comments are pro-socialized
medicine.
This is a forum populated primarily by hackers and people interested in
starting or working at start-ups -- should we also have a single payer of all
hackers? The notion is laughable, but it's put forth seriously when it comes
to medical care. Like all problems of costs being "too high" this one is
caused by artificially restricted supply (govt regulation of medical system)
and skyrocketing demand (much of which is driven by the abysmal nutrition
advice the US govt has doled out over the past 50 years which has only made
2/3 of the country obese and overweight).
Control economies do not work, how much more evidence do we need before people
stop saying "this time is different, we just need the RIGHT people this time"?
~~~

I'm not in favor of single payer healthcare, but to say there's no evidence
that it works is inaccurate. Healthcare in Canada provides the same health
outcomes as ours for half the price. If that doesn't interest you because they
do it with the wrong philosophy, you're an ideologue. In fact, the evidence
that your proposed changes would give a 50% reduction in cost seems a lot
slimmer than the case for straight-up single payer.

What kind of developer do I need? - xxshadmakuxx
Hello, I'm looking do develop what I would believe to be a web-based app. I do not possess the technical skills to create it myself so I'm kind of in the dark as to where to start and what kind of developer I'd even need. The Idea itself is not particularly new or groundbreaking, but I'd like to improve on what's out there. I'm looking to create a site that lets users input data, choose a "theme" or template, and create beautiful infographics based on the data inputted. The user could then further customize colors and logos and finally, give them the image format to download. Users would have the ability to store logos on the site for easy access to customization of future graphics even set up profiles with color preferences....what kind of developer would I need to accomplish this? How could I vet them and make sure they know their stuff? and what would it possibly cost to create something like this? Thank you for your help and experience.
======
jayhuang
I'm mostly going to comment on the latter part of your question about vetting
a developer for this project.
As you mentioned you don't have the technical skills to create this project
yourself, it would be quite difficult to be able to vet someone more reliably
than random chance.
Obviously it would make sense for you to ask to see any related projects
they've made, but I'd recommend having a technical friend help out with the
vetting. Aside from past projects and their contribution to these projects,
perhaps ask for a high level breakdown of how they would tackle this project.
Have your technical friend to overlook this breakdown should weed out people
who'd have little chance of delivering.
Hopefully others can chime in here, good luck!
------
willwong
If you have the money for it, I would suggest going with a service like
ziptask or gun.io. They will do all the technical heavy lifting for you
(figuring out requirements, vetting / hiring, project management, testing).
You will likely spend around $15k-30k (very rough estimate) and have your app
within 3-6 months. Then you will pay a couple hundred a month in
server/bandwidth costs to keep the thing running.
Otherwise, you are looking for a "full-stack web developer". Though I would
really suggest going with an agency for a project like this. Hiring and
managing freelancers is hard.

I use an iptables rule like:
# connection limit for HTTP
-A INPUT -i eth0 -p tcp --syn --dport www -m connlimit ! --connlimit-above 128 --connlimit-mask 24 -j ACCEPT
This basically means, "only accept requests to port 80 if the /24 has fewer
than 128 open connections". It is to kill things like Slowloris, but you can
bring the limit down and kill scrapers. You can also block based on connection
rate:
-N RATE_CHECK
-A INPUT -p tcp -m multiport --dports www -m state --state NEW -j RATE_CHECK
-A RATE_CHECK -m recent --set --name RATE
-A RATE_CHECK -m recent --update --seconds 60 --hitcount 4 --name RATE -j REJECT
-A RATE_CHECK -p tcp -m multiport --dports www -j ACCEPT
This will deny any connection that is the 5th connection or higher in a single
minute. I use this rule for ssh and smtp, but some tweaking might be adequate
for a web server.
(Note: all these rules are for default deny with a rule like "-A INPUT -m
state --state ESTABLISHED,RELATED -j ACCEPT" to ignore established states. If
your firewall setup is different, then the rules will need to be modified.)
There is also a program called fail2ban that will read logs and apply
temporary bans based on what the logs say.
My solution to this problem is to just cache agressively. Hundreds of requests
per second is nothing for Varnish.
~~~
ehutch79
be careful with things like this, it could get you locked out of your server
very quick.
denyhosts and fail2ban are better ideas for dropping bad actors on the net.

It's not a problem; the rules only apply to eth0, but I connect over tun0.

Feed them rss containing uniquely generated strings. Then google for the
unique strings.
Also, block generic user-agents on rss feeds. Most everyone was able to change
theirs for delicious, and we did an insane amount of rss traffic.
~~~
a5seo
I found this to work very well.
Only thing is you need to append keys randomly, say one out of 5 requests, in
different locations if possible. And you should hand out 20 or so different
unique strings.
Then use google alerts to find them republishing your stuff an send DMCA
takedown notices with Google (don't send them a c&d first so you have the
element of surprise and maximum chance of causing real pain). If they don't
take care of the DMCA issue with Google, Google will remove their pages from
the index. They won't know why but their site will slowly die.
~~~
joshu
google alerts = clever.
the other thing to do is include some some encoding of the served-to IP
address (maybe md5 of the first and last half of the IP?)
~~~
ay
To generate the unique string, do SHA1(content + TheirIP + unique secret). The
chance of collision is practically zero. Also, you can then conclusively prove
that it was _you_ who created this unique string - which may come in handy.
(Talking about SHA1 because I used it myself in a lighter version - just a
hash of my name - to check how the search engines work with the content of my
little blog).
~~~
a5seo
I like it, but you need to do this in a way that you append a
known/deterministic string so you can monitor THAT one in Google Alerts.
I don't care whether the unique strings collide (although I love the idea of
being able to tie the IP address of the crawler to the page on which the
content was published for maximum evidence collection), I just want Google
Alerts to find them reliably AND I don't want the spammer to catch on and be
able to easily remove the unique strings before I catch him.
The only way for him to find my little landmines (to strip them) would be to
read through every piece of content he scraped from me.
~~~
ay
By the way - thinking of all this - why would not you turn this scraper into a
free advertisement for you ? If you can detect when it crawls your site, just
insert randomly the backlinks to your site into the content you give out to
them.
This way you will _want_ that they steal more from you :-)
(how to put these backlinks in a way that would be difficult to remove - is
another story. But if you use other links, e.g. tinyurl, in your material -
then you could probably use that :-) Still fairly simple to remove but would
require more work from them.)

subway
Interestingly I don't see any mention of your robots.txt, or if the scraper
identified themselves in the UA string. If the person or organization running
the scraper is legit, they would probably like to know their software is
misbehaving, so that they can fix the issue. Did you attempt to contact them
before launching into a cat and mouse game?

Yeah, definitely try contacting them first. Even if their software is being

Riot Games Approach to Anti-Cheat - cammm
https://engineering.riotgames.com/news/riots-approach-anti-cheat
======
exgamedev
Back when I worked in games we would detect cheaters and then shadow ban.
Quarantine them by only matching them into games with other cheaters.
You may still have to ban them from certain elements of your game, like player
economies (auction house, etc). But the more legitimate their experience looks
the better.
The idea is that instead of fully banning them and triggering the next
iteration of the arms race, you trap and release them into a competitive arena
for cheaters. It's actually fun for them to compete with each other at who can
cheat the hardest and no one else gets hurt. We hooked them up with a
community rep. They found bugs and generally improved our security. Everyone
won.
There's no way to win with an adversarial approach to cheating IMO, not when
you let the client run on their machine
~~~
reificator
Sure. Until you're playing Dark Souls for the first time, you get summoned to
help someone with a boss, and then get invaded by someone with a 360 degree
one-shot kill spell that breaks all your weapons and armor, gives you an
egghead that you can't remove unless you know where to go, and gives you an
item that marks you as a cheater so you now get constantly invaded by
exclusively cheaters.
The item that marks you as a cheater might have been a drop in another
invasion, I don't remember. The point remains, once the cheaters realize you
have a separate cheaters' matchmaking system, they will weaponize that too.
~~~
dkersten
> The item that marks you as a cheater might have been a drop in another
> invasion, I don't remember.
I believe they can do it completely passively, so you’re kinda screwed if it
happens to you :( This is sadly the nature of trusting what clients send you:
a hacked client can send whatever it wants and the “anti cheat” in Dark Souls
sadly seems to simply just check if an item should be possible, meaning a
cheater can trick the game into punishing non-cheaters. Luckily this hasn’t
been a problem for me on console, but it certainly does suck on PC :(
~~~
reificator
And of course, if it didn't punish non-cheaters, then cheaters could simply
cheat the items in on one account, invade/summon another of their own
accounts, (or passworded summon in the remaster) and then give the new account
the items.
There's no winning against cheaters as long as you trust the client. (And it's
possible to do it on consoles too, just more rare as the tools are readily
available on PC.)
~~~
dkersten
> There's no winning against cheaters as long as you trust the client.
Indeed.
> And it’s possible to do it on consoles too
Sure, but the barrier to entry is higher, so its not done as often. I’ve never
_noticed_ someone who was obviously cheating (which doesn’t mean I’ve never
encountered any, but if I have, they’ve never been so severe as to do the
things mentioned here or for me to notice it)
------
Teknoman117
I have mixed feelings about anti-cheat, especially in the last few years. A
lot of them are getting rather intrusive. Take Player Unknown's Battlegrounds
for instance, which uses BattlEye. It actually injects a kernel mode driver
into Windows that spies on whatever else your system is doing and exfiltrates
unknown data in the name of "guaranteeing a fair game experience." I didn't
even realize that this is what it was doing until my system crashed one day
and the cause was some .sys file in PUBG.
It'll also randomly kick you from games for having various programs installed
or running. Programs such as VMware. You have to disable all VMware services
or PUBG will kick you randomly for using "unauthorized applications." God
forbid you have any VMs running, that might amount to a ban (seriously).
Worse still is that when you take your complaints to their social media, or in
anyway speak ill of it, you get hordes of fanboys saying that you shouldn't
install anything other than games on your PC or you're a dirty cheater. "Oh
you want to do things _other_ than gaming on your PC? You should buy another
PC then."
Don't even get me started about trying to run games in a virtual machine w/
GPU passthrough. The communities will tear you a new one telling you to do
things "normally" and by attempting to use anything other than the "normal"
setup makes you a cheater. Just google anything like "steam vac kvm" or
"battleye kvm" and you'll get hordes of people claiming they heard some guy
say virtualization is the future of game cheating therefore VMs are cheating
tools and should be banned.
Seriously, if I could get a refund for every game that uses BattlEye, I would
try.

So I'm not seeing anything particularly novel here. In fact, I think most AAA
titles do most if not all of these things today. It really just boils down to
understanding your title's threat model and mitigating the threats.
I think the article missed an opportunity to talk about false positive rates,
the workflow for users to get unbanned due to false positives (usually a very
nasty process), performance, platform support (Windows, for example, has
encrypted app packaging [1], anti-cheat monitoring [2], and protected
processes [3] built in), and the privacy implications of uploading non-game-
related Windows driver and process data.

the evidences.
~~~
half-kh-hacker
Videogame cheat developer here (although, not for the game mentioned in the
article) -- The mentality of game companies is if the 'evidence' of the anti-
cheat flag is made accessible to users, cheat devs will use the same evidence
to overcome the existing detections in place.
The oft-used 'arms race' analogy for this would be like sending blueprints of
your newly-fabricated weapons to the adversary.

The fact is 99 out of 100 banned users were actually banned for good reason

everyone's enjoyment of it. That less than 1 percent that is truly innocent is
nearly impossible to service because of all the noise.

Cheating definitely sours a gaming community, as does falsely accusing people
of cheating. I left the original (circa early 2000s) Counter Strike community
after being routinely accused of cheating. I have never once cheated in a
online multiplayer game. But, some people just couldn't grasp that I was
really that (comparatively) good & quick of a shot. Also, I don't think they
realized that certain materials could be shot through with a powerful enough
weapon. I probably had a bit of a leg up on most people, too, as I had state
of the art hardware for the time (I had dual P4 Xeons, 3GB RDRAM & the best at
the time GeForce AGP card in 2002) and a single to low double digit ping for
most servers being on a university OC-3 line.

Your comment reminded me of a frustrating evening on bzflag.
Long ago I was using a custom Linux box with a slow GPU, and on one map no
matter how hard I tried (and no matter how many fellow players watched trying
to help me get the timing right) I simply couldn’t jump to the first level of
a building.
I’d never experienced a hardware limitation quite like that.

Haha neat. That was probably caused by the physics engine running slower than

This is a great technical breakdown of some modern high level approaches to
common cheats. I think this the most transparent approach (even though the
author admits leaving some detail out) to modern anti-cheat for massive
multiplayer games. Good on riot for having an open dialogue about this. I
don't think you'd ever see someone like Valve going a transparent route with
something like this. (Not making a judgement on that decision, just an
observation).
~~~
johnmg
Fair context: I make cheats/utilities this exact game being talked about in
this article, so perhaps my opinion on the subject is biased or even invalid.
I partially disagree about the transparency of this article, while they do
explain most of their approach to anti-cheat (and that is pretty cool for them
to do), they seem to leave out any mention of anything that could be
controversial.
It suppose that it does make sense to not mention the implementation details
of their anti-cheat, but I wish that they would be a little more transparent
about how/when/what they snoop around and send to their servers. The current
Mac game client for League Of Legends contains full debug symbols and it
doesn't have Packman (the packer described in this article), which makes it
quite easy to look through the symbols. Inside you can find all of the anti-
cheat-related network packets, in specific:
PKT_C2S_EnumDrivers PKT_C2S_EnumProcesses PKT_C2S_EnumDrives
PKT_C2S_EnumHandles PKT_C2S_EnumRecentFiles PKT_C2S_EnumModules
PKT_C2S_ProcessorData PKT_C2S_SystemState PKT_C2S_ModuleLoadNotification
PKT_S2C_SendModule PKT_C2S_ModuleResponse
Now, I personally expect anti-cheat to snoop around my system when I'm doing
something shady like scanning its memory. However, if I was a normal user of
the game, I would be a bit concerned to know that it might be sending my
recently used file names, drive names, system driver names, currently running
processes, processor information, system state, and even entire binary files
that it automatically deems as "suspicious", to their servers.
~~~
ipython
Wouldn't that run afoul of GDPR?
~~~
munchbunny
Not necessarily. GDPR isn't a blanket ban on collecting/using this info
without consent, it's a policy that consent is required for non-essential
collection/usage. You could argue that anti-cheat is essential for an online
multiplayer game like this.
I think it's sketchy to collect this much info, but I don't think it's
explicitly illegal.
~~~
mikekchar
It's a bit more complicated than that. You have to do a few things. First you
have to tell the customer that you are collecting their data. Then you have to
tell them under what lawful basis you are collecting their data. The user then
has various rights (depending on the lawful basis you choose) to object, etc.
If you must collect and use the data in order to fulfil the contract (i.e.,
there is no other way to do it -- for example you need to get their address in
order to ship them a package), then you can just do it (as long as you tell
them that you are doing it). For most other lawful bases, you have to allow
them to object, in which case you have to stop using the data.
I think the real question is whether or not the information in question is
personally identifiable information. If it's not, then GDPR doesn't apply. I
think you could make a pretty strong argument that it doesn't apply, as long
as you take pains to ensure that you can't identify the person from the
information.
~~~
civilitty
> I think you could make a pretty strong argument that it doesn't apply, as

That would entirely defeat the purpose of an anti-cheat system. You have to
have some sort of personally identifiable information attached to the data
being sent in to the server, otherwise how are you going to ban the cheaters?
Even IP addresses are personal identifiers as far as the GDPR is concerned and
even if they're not storing it long term, just sending the user data over the
wire is enough to trigger the data collection portions of the GDPR.
~~~
mynameisss
Instead of using an IP address to identify cheaters the game could assign a
unique random generated ID to players. Then they could ban that id without
using IP. I think this scheme complies with the GDPR if you take care of not
binding that ID with other user personal information.
~~~
lwansbrough
If you can identify a physical person with a unique identifier, it is PII
according to GDPR, I believe.
~~~
mynameisss
You can apply a one way function to an IP to obtain an ID and then maintain a
database of bad IDs. For example you could compute this ID by the SHA256(IP +
secret salt). Since way one function don't allow you to recover the IP, the ID
is not PII. If you detect an IP which has bad ID the connecting ban that IP
from the game. I think this respect the GDPR, you don't maintain a list of IPs
or any other PII.
~~~
civilitty
The second you use this ID to tag data you're sending over to the servers,
that ID could easily lose any claim to anonymity for the purpose of the GDPR
because the anti-cheat system vacuums up a vast trove of information. All it
takes is one email "Re: Claim for Your Local Psychiatrist Bob" or a document
named "John Doe Jr - First Grade Book Report.docx" showing up in the titles of
your open windows (that many anticheat systems send to a remote server) and
boom, that ID and all of the data attached to it are now a radioactive
liability.

stcredzero
Here's my project's approach to Anti-Cheat.
1, 2, 3) Everything on the server. Server's version always wins. Server is the
authoritative source. Granted, I have a mathematical advantage in the game's
particular movement mechanics which makes this easy to get away with. The
other game mechanics are also designed with facilitating this in mind.
Corollary: The client is almost nothing and trusted with nothing. It's pretty
much a dumb terminal for displaying moving things, syncing their motion with
the server.
4) Scripting -- if you can't beat 'em, join 'em! We're going to publish an API
to allow for user scripting. We plan on releasing the client as Open Source,
allowing people to modify and extend the client.
5) Cryptographically hard RNG and procedural generation. If you want to know
what's in Star System 7, Galaxy Grid 123987236-87324958, you're going to have
to go there yourself. We don't even know ourselves!
Regarding #4 -- This is going to be a design philosophy. Anything we can't
enforce, we will allow and co-opt into the game!
~~~

infogulch
The game is 100% online. Could you have a piece of the networking protocol
where the server sends little snippets of executable code over the network
_during the game_ that read some specific locations in memory, do some
processing, and send the results back to the server in the next packet? You
could do things like check the starting address and length of loaded dlls, or
take the hash of some random span of machine code, or even random locations in
the heap, all of which may or may not actually be verified on the other end.
You can use any number of obsfucation tricks to hide their purpose (if they
even have one) and you could even randomly generate them. And since the server
expects the response in the next client packet it would be literally
impossible for a cheater to manually deconstruct them, and even be difficult
for automatic analysis tools to have enough time to do anything meaningful
with it.
You can reduce the security nightmare from the user's perspective by only
allowing machine code that's on a tight whitelist. Allow it to read from
anywhere, and only let it write to a dedicated little sandbox area with e.g.
fixed addresses.
~~~
bitexploder
If you restrict the machine code it makes it that much easier for me to write
an emulator to execute your machine code and return the result. It might even
be trivial. It is a never ending Ouroboros. You build a more clever mouse
trap, I will design a more clever mouse. If I have all your code and am
running it on my computer it will be a matter of time before I can back out
whatever obfuscation or technique you are doing and undo it. You may have some
hope in network delivery of graphics only. If I am not running the game client
code, and just streaming the game from one of your servers, you have a chance
at keeping your client safe.
~~~
jonjojr
"If I have all your code and am running it on my computer it will be a matter

sure try to undo a block-chain and see what happens.
The code will be encrypted with a unique key that will need to be registered
on the server with your account. Change that code and it invalidates your
entire build along with your account. case closed.
~~~
bitexploder
I think you are missing my point. This concept in client computing security
basically chains back to the halting problem. You can't /know/ what I am doing
with my computer. You can build a very elaborate trap / obfuscation and it
might be hard, really hard, to defeat it or circumvent it, but it is a
certainty that I can. The block-chain has absolutely nothing to do with client
code security because it has a network enforced mechanism. What the
grandparent was suggesting was running some nugget of code in a little VM (or
actually on my machine), computing a result, and then returning the result to
the server to make a security decision. The problem is I control that machine
performing that computation and your security decision as the server is based
solely on the computation performed on my computer. A skilled reverse engineer
will just hook your code in the right place, intercept that security check and
have it return the right bytes back to your server, while still doing whatever
client side cheats they wanted to do.
[https://en.wikipedia.org/wiki/Rice%27s_theorem](https://en.wikipedia.org/wiki/Rice%27s_theorem)
<\--- this is all about program behavior and did the user actually run the
code you sent them. Block chain is about "did I possess certain data" (such as
a private key to sign a transaction) and not about "did I run certain code".
~~~
mikekchar
You are absolutely correct, but it occurs to me that CPU designers could
actually implement a kind of RSA style memory fetch instruction. The CPU would
generate a public/private key pair, where the private key is not accessible by
any means. The client would send the public key to the server, which would in
turn encrypt the memory location(s) that it wishes to inspect. There would
then be an instruction on client's CPU which would accept that encrypted
memory location and return the contents, without divulging location. The CPU
could regenerate the public/private key values for each request. I can't
imagine defeating that kind of scheme without hardware hacks. The more that I
think about it, the more I wonder why no-one has done it before, because it
seems useful. Probably there is something I'm missing...
~~~
unknownid
How do you prevent the cheat doing a MITM attack and changing keys?
~~~
mikekchar
Yes, you are right. That's what I was missing :-)
~~~
bitexploder
The answer, and it has dark implications, to me, is Trusted Computing. Never
let the user have full control. Do this key exchange on a base OS or some
other VM the user can never touch (e.g. Knox / TrustZone). Still, we can
exploit our way to this trusted OS and MiTM there, but it takes much more
skill. With Trusted Computing the base OS can more simply install a "spy" to
keep track of a games memory / code to ensure it is only ever loaded and
executed from memory that is essentially made read only after the program is
loaded but before it executes. The trusted OS verifies the program code, the
OS, etc, and if it all checks out, let's the code run. Of course it goes back
to the halting problem, but if the programs memory is unexecutable and modern
exploit mitigation is applied the game is now in a considerably sturdier mouse
trap :)

I wonder if Riot would consider building the scripting UI they show into some
kind of training mode. It's a bit like the argument that no one would pirate
if they content was easy to get for a reasonable price.
If players could train with the spell range circles, skill shot path
projection, last hit helpers, etc in a sanctioned way, I wonder how much this
would remove the desire to seek out the cheating programs.
Edit: I see they have a "training mode" already:

The game would probably be more vulnerable then, because now you have "cheat"
scripts designed to work with the game.

People who cheat aren't trying to practice; they're trying to win games. There
already exists a "practice mode" which lowers cooldowns and shows tower
ranges. And it doesn't make sense to practice with cheats because it won't
help you play the game without cheats very much.

That's possible. For example, World of Warships is a game where you fire big
ship-mounted guns and must learn to take shell travel time and target relative
velocity into account to hit moving targets. There used to be a cheat which
did those calculations for you and showed you a reticle you could aim at
instead. IIRC this cheat relied on code that existed within the game already
and was just not used.

They broke GPU passthrough setups as well at first. There was some community

Message to EA: don’t try to be clever. Make simple query based bans, after the
fact. Sift through the event tables and make trivial questions like if A
killed B with a weapon that is not possible to use on the map - then he
cheated. Check for ridiculous (not just suspicious) activity.
The cheaters that ruin games aren’t the ones that make players better such as
discrete wallhacks. It’s the trolls that are immortal and flying. They
blatantly cheat just for the response to their trolling, and they empty a
server in a matter of minutes. But just _because_ they are so very blatantly
cheating, they should be quite simple to detect in logs too. If someone has
200 kills with an ammo box in a 5 minute round that’s enough to say it’s
definitely a cheat. Yet these people do it over and over with NO obvious
response to reports. Focus on THIS type of cheating (which is _trolling_ , not
gaining an advantage). Only after that look at more subtle cheating.

pythonaut_16
I'd love to see a game where cheating and scripting is the primary means of
gameplay. By default the game would present a very simple UI but players would
be encouraged to write and share scripts enabling varying levels and types of
functionality.
As a game developer your job then would be to write interesting enough systems
for players to exploit to come up with interesting gameplay. I can imagine a
scenario where different Overwatch-style "classes" emerge all built from the
same basic game elements.

I am surprised people don't virtualize the game and do their analysis at a
level that the OS and game can't detect. Ultimately, these games trust that
the hardware they're running on behaves according to specification. That is
clearly an unwise assumption. Cheaters may not be taking this path today, but
it gets easier and easier as time goes on, and it sounds like they're not
prepared at all. (Some other comments mention that current games look for
virtualization software installed on the same OS install that the game is
running on and fails the integrity check if found. I can't imagine that stops
anyone actually determined to cheat. I imagine it annoys people that test
their Docker images on the same machine they play the game on, though.)
Even if virtualization is detectable, you can also take the computer entirely
out of the loop. The state of the art for aimbots seems to be reading game
memory and applying synthetic mouse movements at the OS level. That is quite a
blunt instrument to apply and I'm sure that no game has a major problem with
this kind of aimbot. A more elegant aimbot would look at the video of the
game, look for targets, and provide the necessary mouse movements over USB. At
best, the only countermeasure is to make enemies harder to see or to learn
some heuristic in mouse movement that differentiates the bot from a human...
but injecting randomness is straightforward and nobody needs a 100% accurate
aimbot anyway. The pros destroy you with 30% accuracy.
Finally, it's unclear if there is even any advantage to be gained by cheating.
If you want a higher rank in a competitive game, you can just pay someone to
play on your account. From what I've read on Reddit... many of the people
offering these services are apparently professional players. No anti-debugger
hook is going to detect that.
It should be interesting to see how this advances. While games that rely
solely on mechanics or information hiding are clearly doomed in the long run,
it's probably good news for the rest of the software industry. What is your
cloud provider really doing? Is your own software compromised? The tools used
to cheat in games will be quite valuable in answering these questions and
protecting your users from people that actually have something tangible to
gain from these actions.

IMO games should encourage ergonomic aids. Why allow the UI to be a limiting
factor to how you want to play?
For example people used to talk about APM in SC2 as a sort of measure of how
good someone is. Why should that be? It's a strategy game. Imagine if you
could express your ideas effectively into actual game actions?
~~~
echohack5
(As a former high level StarCraft / SC2 player / caster).
It's not chess. That's why.
There is a real physical aspect to the game. Training your fingers to hit
certain combinations quickly to execute build orders, and mix in micro is key.
Pro players use hot packs to warm up their hands, or glasses to aid their
eyes.
The game developer takes a lot of care to ensure the UI / hotkeys / peripheral
setups are optimized for pro players.
Using external tools to defeat this setup simply isn't fair and diminishes
skill built into the hands and muscle memory of players. Even at a mid-level
of skill, people learn simple combos. For example, a Protoss player hitting
"4+e" because that's where they have hotkeyed all their Nexuses and e is the
hotkey to build probes.
~~~
maerF0x0
Many responses are saying the same thing, so I'm going to respond to you ...
> It's not chess.
I agree it's not chess, and chess often has a time component to it. The
realtime nature of a game doesnt mean you should have to be able to "move" in
realtime, IMO it would be superior if it tracked more closely to your ability
to react, intellectually, in realtime. That is, real time thought more than
realtime motion. Ergonomic aids would help people to convert their thoughts
into real game plays without limiting them to their body's capabilities. But I
also admit this is my opinion and it's clearly an arbitrarily decided dividing
line between how much should a game be about myelinating certain move patterns
(spread out troops, cast a spell, select production groups) and how much a
game should be about quality of thought in realtime (I see he made units X,
How am i going to respond? I have many minerals, should I spend them on tech
or units?) ...
~~~
vkou
With enough mechanical aides, the game balance breaks.
For example, SC2 has a very cheap unit called the roach. When burrowed, it
can't attack, but regenerates health incredibly quickly.
It's trivial to write a cheat that will, whenever one of your roaches starts
taking damage, causes it to burrow, and whenever it stops taking damage,
unburrow.
The unit is balanced around human control - no human can, with perfect
accuracy, choreograph burrows and unburrows of individual roaches in a pack of
~60.
With such a cheat, roaches punch way above their weight, completely breaking
the rock-paper-scissors balance of the game.
~~~
maerF0x0
I do not deny that the game mechanics would vastly change. The strategy would
shift away from "How can I micro these roaches" vs "How can i effectively
attack burrowing/unburrowing roaches" to "How can i ensure I get roaches" vs
"How can I frustrate/prevent my opponent from getting them in the first
place"... As an aside, ANY change to a game is going to disrupt the
equilibrium in some manner and I assume would require human intervention to
re-establish a "fun" gameplay.
~~~
vkou
> How can i ensure I get roaches
Which is trivial for any skilled player, because they are an incredibly cheap,
low-tech unit, and passive base defenses are currently very good at fending
off very early aggression.
> As an aside, ANY change to a game is going to disrupt the equilibrium in
> some manner
Yes, and sometimes, the equilibrium settles on an incredibly shallow,
uninteresting game-space.
StarCraft is a game of a number of rock-paper-scissors cycles, all operating
at the same time. Greedy expansion - versus rushing versus safe plays. Economy
versus army versus tech. Roaches versus marauders versus zerglings.
Sometimes, due to patch changes, poor balancing, or because player skill
improved, the game ends up stuck in a quagmire, where the risk/reward ratio
for many of these options is completely out of whack. The game stagnates, and
becomes incredibly unfun to play, and to watch.
Throwing a wrench into balance, by allowing auto-scripts, which have an
incredibly uneven effect on the different units, mechanics, and races in the
game is far more likely to push it into an unfun equilibrium, then a fun one.
~~~
maerF0x0
Yes, but keep in mind this idea and thread is not about SC2 specifically. It
used SC2 as an example of the class of games that I personally believe I would
find improved by removing the mechanical aspect of the game allowing me to
focus on the fun part -- Making decisions and giving instructions patterns
more than "micro"

Great write-up. I'm my job we spend a lot of time dealing with hackers and
cheats for our mobile and PC games.
We tend to see similar exploits across all our games (memory hacking, fake
IAPs, etc) which lets us build an armoury of anti-cheat tools.
What I find most interesting is where hackers don't focus their attention. It
took almost 4 years for them realise the encryption key for our assets was
easily accessible using the 'strings' tool in Linux - once they found it we
had a busy few days stopping modders from impacting legitimate players.

sthomas1618
I think he's implying a cheater's injected DDL would be tailored for a
specific build, so if they shared it with others, it would be ineffective. And
not only that, but based on how the Cheater.DDL is targeting the build, they
could identify the account that made the cheat.

walrus01
One of the things I'm not seeing is what kind of statistical data they're
collecting and storing for prevalence of discovered cheats/scripts/bots, on a
per-ISP basis. Since they know and log the IP that every user connects to the
game from, they can certainly profile it down to at least as granular as the
individual /24\. For example if there's a college dorm full of students where
somebody has shared a recent script/bot, the behavior could be correlated
between time, place and IP.
Thereby allowing them to develop IP space reputation lists that contain the
relative likelihood of bots/scripts being run (sort of like SMTP spam RBLs,
but not an all-or-nothing, more of a weighted distributed reputation scale).
There is also a league of legends mobile android/iOS app. If you set it up to
require location permission, they could begin to correlate the physical
location of cheaters with their specific IP block. For example if somebody is
at home on their wifi, their phone is connected to their home router, and
their desktop PC with a cheat script are all going outbound to the internet
through the same NAT, and coming from the same /32 (in ipv4) address.
I'm willing to bet that if plotted on a map you could develop hotspots. Of
course they would also match the density of players in general. But perhaps
certain trends could be identified.

Aren't there massive video latency issues with this? People spend tons of

stcredzero
You can have real-time games whose mechanics are designed around latency. My
game is one example. In fact, I would assert that for now, you have to design
around latency in real-time multiplayer games. Until round-trip latency for
your entire userbase is below 40ms, it will be an issue.
~~~
earenndil
I'd say 30ms, not not 40. Because a single frame is 16.6ms, so 30ms round-trip
would bring one-way down to below one frame of latency (potentially with a
small amount of jitter).
~~~
stcredzero
It sounds surprisingly high, but a lot of the population won't notice 40ms
round trip. Some of it will know. It also depends on the game's mechanics. Not
all games are FPS. Not all games have action significant down to one frame.
Some of my favorite real time games involve making decisions about once every
5 seconds which will result in a turning point in another 15 to 30 seconds
which will get you killed or leave you victorious.

What I wonder is how the encryption keys are stored. There are obvious ways to
obfuscate keys, but at decryption time, the keys need to be exposed plainly in
memory, don't they? So how do game makers like Riot prevent debuggers from
discovering the keys and revealing them to everyone? Does every player have
different keys?

A good solution will not only generate keys for each player, will even
generate different keys for same player each time that player starts a new

All anti-cheating techniques are fallible. It's impossible to build a perfect
cheat detection/prevention, just like it's impossible to build something that
will always detect all malware, etc. The client code is always going to be on
the player's computer and has to execute on the player's computer. There's no
way around that.
You can't guarantee effectiveness, but you can make it very hard to reverse
engineer and circumvent, and you can constantly change techniques so that
adversaries need to put in more work. It's an ever-evolving cat-and-mouse

You won't find any companies with competitive online games that turn a blind
eye to cheating. If you consider a game with a cheater as being ruined for the
other players, a very small number of cheaters can ruin games for a large
portion of the players.
For a rough example of how the math works, let's say we have a game that is
5v5. If we have 100 players, 1 player cheating, and everyone plays once you
end up with 9 players having their game ruined. That's 9% of players impacted
by having 1% of the players cheating.
~~~
mikec3010
I'm not suggesting they tolerate it completely. Just that they make the game
slightly "cheatable" then counteract it enough for there to be a known
controversy.
~~~
fredophile
No one is intentionally making it possible to cheat in their games. Cheaters
and cheat detection/prevention are in a constant arms race. You can't just
allow a little cheating. The people that develop cheats will share them and
those cheats become more widespread.
Your whole argument is also based on the idea that there is no such thing as
bad publicity. This is incorrect. If your game gets a reputation for being
full of cheaters then people will leave your game and probably not come back.
If the first time you hear about a game, all you hear is that it is full of
cheaters are you going to head out to the store to buy a copy?

mopierotti
The first point is actually something that game developers have failed to do

very little data, they may only send player inputs across the wire, meaning
that each client needs to know everything, even if the final decision about
game state is made by a server.

Yeah, the same many developers haven't escaped strings they inserted into SQL
tables, leading to SQL injections. Does this mean if I don't do that I have a

include many advantage a blockchain can provide during multiplayer games.
EDIT: yes it is a very unpopular topic, but deep down many of you who are
developers, know that blockchain can solve many of these issues with
cheater.dll

lucb1e
Reason for downvote: you seem to have no clue about blockchain or cheater.dll
whatsoever.
~~~
jonjojr
Blockchain is all I work on and you seem to not understand my suggestion.
cheater.dll needs to be loaded in memory along with the game. Correct, right?
If the original build of the game has already generated an encryption key that
is stored on a server or a distributed ledger using your account, then
tampering with the origonal build in memory will result in generating and
invalod key thus changing the ledger or the stored key on the server, and not
matching the ledger. If this happens then it invalidates your build and the
distributed ledger would need to updated, but since that is not allowed in
this instance all ledgers would reject your change and flag the block and the
account. Making it easier to find who attempted a change. Sure this can be
done on a server but because of the tamper proof inherited by a distributed
ledger it would make it harder for this code to be shared. The cheater can
still change the code but it would not be able to share it.
~~~
BenjiWiebe
How would it invalidate the build? How would the server find out the build was
tampered with? Why would my hacked game add anything to a blockchain? I've
followed blockchain tech closely since '13 and your comment makes no sense.

OCaml: what you gain - edwintorok
http://roscidus.com/blog/blog/2014/02/13/ocaml-what-you-gain/
======
nathell
I have very fond memories of OCaml. It was OCaml that introduced me to
functional programming, way back in 2000 in my freshman year at the uni. I'm a
Lisper/Clojurian these days, but I think warmly of OCaml's type system, the
speed, the self-containedness of the distribution, and the fact that getting
the code to compile tends to mean getting it to actually work.
My #1 gripe with OCaml is the fact that its strings are composed of single-
byte characters. I know there's Camomile, but not having it as part of the
language core creates a sense of disintegration akin to PHP and Python 2.
There's also this: [http://www.podval.org/~sds/ocaml-
sucks.html](http://www.podval.org/~sds/ocaml-sucks.html) which I mostly agree
with.
But, all in all, OCaml rocks.
~~~
fzltrp
> I know there's Camomile
Camomille is great, but it exhaustively covers the _whole_ UTF standard, which
you might not need for more casual uses. There are other libraries bringing
lighter support for UTF strings (ocamlnet for instance I believe).
Nevertheless, Camomille does a pretty good job if you're concerned by
compliance.
> There's also this: [http://www.podval.org/~sds/ocaml-

It's a pretty old page. I'm not sure its content is still accurate. I'll have
to look into that.

Well, I don't know. The "No polymorphism" section is misleading (though
polymorphism doesn't carry the same meaning from one language to the next):
There's this comment on higher order functions not being supported which
surprises me. See the section 7.13[1] and 7.14 of the OCaml documentation.
These features are availabe since ver 3.12 of the distribution.

If you program in OCaml be sure to checkout Batteries [1], it is an extension
(which also replaces some stuff) to the standard library which eliminate most
of the criticisms I had against OCaml. Also, don't try to avoid opam [2], I
didn't really want to use it at first because I always prefer to use my
system's package manager (using Debian), but it makes your life so much
easier.

Do people try to avoid using package managers? Why? On my system I regularly
use homebrew and opam but also have occasional need for pip, cabal and more
recently npm. Not everything is packaged upstream (nor would I expect it to
be).
I can't imagine how the OCaml ecosystem worked before opam as it's rapidly
become a fundamental tool.
~~~
p4bl0
I don't know, my instinct tells me that I should avoid having many independent
package managers in order to keep everything in the same place and avoid
conflicts. But I don't really have any reasons to think that those are better
ways to do things.
~~~
tommorris
My instinct agrees with you, but for one small matter. Ubuntu only just
started packaging Ruby 1.9.3 - a version that came out years ago and which is
to be deprecated next year - in the latest version.
I don't know about OCaml but trying to do Ruby or Python development without
using pip or gems (not to mention virtualenvs or RVM gemsets etc.) seems like
an exercise in futility and perpetual brokenness.
I'd like it if system package managers could actually keep up with the needs
of developers, but they seem to have failed. Until they can get their shit
together, we now have the irritation of managing all these many, many
language-specific package managers rather than just using apt-get like sane
people. If the system level package manager were able to talk to the language
level package managers, that'd be a big improvement.
The number of times I've typed `sudo gem install nokogiri` and then had to
fumble around and work out exactly which variant of libxml-dev-0 or whatever
is needed before I can install a RubyGem with a native dependency shows we've
got some brokenness that needs fixing.

technomancy
> I'd like it if system package managers could actually keep up with the needs

I would argue that they fail at this because it's a goal that's in direct
conflict with their primary goal: to serve end users. The needs of developers
are dramatically different. Having multiple versions of a package is a must
for developers, but would just cause weird unpredictable issues for end users.
(Unless you are very clever and do something like Nix, of course.)

For the early adopters and experimenters amongst you, you might like Felix
[http://felix-lang.org/share/src/web/tut/tutorial.fdoc](http://felix-
lang.org/share/src/web/tut/tutorial.fdoc)
The site is undergoing a major reorganization right now, so some links will
break.
It is a whole program optimized, strongly typed, polymorphic, ML like language
that can interact effortlessly with C and C++ and has coroutines baked in. It
has type-classes as well as modules. Functions written in it may be exported
as a CPython module. This might be useful if one wants to gradually transition
from a Python based src tree.
Its own demo webserver is based on coroutines, this is the same webserver that
serves the language tutorials. It uses a mix of lazy and eager evaluation for
performance and compiles down to C++. Execution speed is comparable to hand
written C++, mostly better. Its grammar is programmable in the sense that it
is loaded as a library. So in the same way that languages may acquire
libraries, Felix may acquire domain specific syntax.
With inaccuracies in analogies assumed, Felix is to C++ what F# is to C# or to
some extent Scala is to Java.
It is also mostly a one man effort but with a feverish pace of development so
it comes with its associated advantages and disadvantages.
Tooling info is here [http://felix-
lang.org/share/src/web/ref/tools.fdoc](http://felix-
lang.org/share/src/web/ref/tools.fdoc)
The author likes to call it a scripting language but it really is a
fullfledged statically compiled language with a single push button build-and-
execute command. [http://felix-lang.org/](http://felix-lang.org/) The
"fastest" claim is a bit playful and tongue in cheek, but it is indeed quite
fast and not hard to beat or meet C with.

OCaml looks really good, I've heard good things about it for awhile now. I'd
like to learn more but and currently learning Haskell and want to focus on
learning that for awhile.
Does anyone know why OCaml gets compared to Haskell so often? It sounds like
OCaml doesn't force a purely functional paradigm on you, so how is it any more
functional that a number of good scripting languages (Python, Ruby, Peal,
etc)?
~~~
tel
OCaml has a similar type system to Haskell's. It has algebraic data types. It
also has all the normal higher order functions and combinators "done right".
It also commits strongly to using first class modules as an organizational
component atop the functional core.
I don't think "functional" means a whole lot. Many languages with lightweight,
first-class lambdas like to jump on that bandwagon by implementing
map/fold/scan/take combinators on lists, sometimes even lazy ones, but that
whole game is just a sideshow to the real meat of what makes Hindley-Milner
typed languages with ADTs quite fun to work in.
~~~
seanmcdirmid
Hindley-Milner is fun until you need nominal subtyping or mutable assignment,
then the whole "semi-unification is undecidable in general" comes up to bite
you.
~~~
tel
How does HM get in the way of mutable assignment?
~~~
emillon
Polymorphism (more precisely, generalization of unknown types) is incompatible
with references. For example:
let r = ref []
Here r has type 'a list ref (reference to a list of 'a where 'a is unknown).
r := ["hello"]
r has type 'a list ref, := has type 'a ref -> 'a -> unit, and ["hello"] has
type string list, so it works (if we instantiate 'a with string).
let n = 1 + (List.head !r)
1 has type int, + has type int -> int -> int, and we can type (List.head !r)
as int since we can type !r as int list since we can type r as int ref list
(this time instantiating 'a by int).
So, we just added an int and a string and the program will probably crash.
What's wrong is that every line is correct but because of the mutable store,
the program as a whole is incorrectly typed.
The solution is to generalize only a subset of all syntactic constructs. The
historic solution in Ocaml is to never generalize expressions that may
allocate memory (that's the "value restriction") . For example, a function
application (like f x, or ref []) may allocate, but a variable or a constant
(like x or 1 or []) can not. That's why [] has type 'a list but ref [] has
type '_a list ref ('_a can be unified only once, so in the above example an
error would occur at the "let n").
~~~
tel
Ahh, that's sort of obvious in retrospect, but I was blinded thinking in terms
of Haskell where IO protects against such generalization.
~~~
emillon
The equivalent Haskell program is
import Data.IORef
main :: IO ()
main = do
r <- newIORef []
writeIORef r ["Hello"]
x <- readIORef r
print $ x + 1
return ()
The reference is bound by "r <-", ie a lambda (as this desugars to ">>= \ r
->"), and lambdas are never generalized (even in ocaml).
I think that the reason why it works is that because there is no way to let-
bind r except with a toplevel unsafePerformIO.
~~~
tel
Yup, that's precisely what I forgot to think about.

I'm planning to learn ocaml in the coming weeks, as I want to try ocsigen
([http://ocsigen.org/](http://ocsigen.org/)). Seems to me there is good
activity in the Ocaml community lately (eg new books came out recently)
~~~
p4bl0
I like OCaml but really, Ocisgen is crap. People making it have no idea how
today's web works.
Some parts of it (lwt, js_of_ocaml) are nice and maybe useful piece of code,
but you don't want to use the framework as a whole to develop a webapp.
The problem with Ocsigen is that it reinvents the meaning of everything, even
the HTTP verbs, to suit its internal needs. For example, it is not possible
(or it must be very painful) to make an API for your Ocsigen app so that other
apps can interact with yours. First, you have to forget PUTs, HEADs, and
DELETEs, but also GETs and POSTs are used incoherently by the resulting code
to update parts of the webpage, submit forms, etc.
If you want to make a site/webapp that only focus on itself and never have to
interact with anything else than its visitors, then Ocsigen might be a
suitable tool for the job, otherwise I wouldn't use it.
Disclaimer: I only used Ocsigen for one day, it was at JFLO, which expansion
in French would translate to French Ocsigen Lectures Day. I get what I know of
it and what I'm saying here by the day-long courses and hands-on tutorials
given by Ocsigen developers and by discussing these problems with them
afterwards.

That's called a "god object", unless I'm mistaken. It's an abomination in any
language. I have the misfortune of maintaining a codebase with this "feature".
Never, ever, do anything like this.
~~~
raphinou
Never used or inherited such a design, but I'm curious about what practical
problem you encoutered. Care to illustrate?
~~~
mercurial
Once you have implemented this design pervasively, you can forget about
reusing your code in another context. Because it is impossible to tell which
part of the god object is needed in a given part of the code, you have to
initialize everything in the god object. With a bit of luck, you're working in
Java and mixing this anti-pattern with some Spring dependency injection, in
order to make this mess really impossible to untangle.
And obviously it encourages mixing up layers. Why have modularity when you can
access your data access components from anywhere?
And in general, circular dependencies are a code smell. Whenever I thought I
needed to use them, I came to realize it was the wrong decision.

OCaml is a great language, but IIRC the creators didn't talk much to the

The conversation between the OCaml creators and the community is a lot more

the main team once a year, and air our concerns in a structured way. This is
so much easier to handle than a firehose of e-mails. Nowadays I still attend
the annual Consortium meeting, but more in a capacity of reporting on our
activities at OCaml Labs and there are still a healthy set of industrial users
who like this mode of interaction.

I don't know how other similar languages deal with GUI. It's always sort of
hairy, obscure code when you look at it closely. Mainstream languages (like
Java) usually give you GUI building tools which generate all the boilerplate
stuff, but if you look at that generated code, it doesn't look so appealing
either imho.
If you know the GUI libraries inside out, then the code becomes much easier to
grasp though. The lablgtk library (which provides gtk support) is quite well
written, providing both a modular interface and objects, but indeed there's a
learning curve.
Lastly, you might find it more palatable with a little bit of formatting:
let menu = GMenu.menu () in
let explain = GMenu.menu_item ~packing:menu#add ~label:"Explain this decision" () in
let callback () = show_explanation impl in
explain#connect#activate ~callback |> ignore;
menu#popup ~button:(B.button bev) ~time:(B.time bev)

The best languages for GUIs I've seen are specialized declarative DSLs. Things
like QML, XAML, JavaFX FXML, XUL, and even HTML. Anything else very much
sucks, in my experience.
~~~
danieldk
And Qt pre-QML. The user interface is declaratively described in XML (which
can be edited visually with Qt Designer). You then use a utility (uic) to
generate e.g. C++ class which you can use through composition and inheritance.
UI events are wired to code through Qt's signal/slot system.

In praise of Dewey - wallflower

======
spodek
One of my favorite observations from John Dewey is that children constantly
ask questions... except in the classroom. It's worth thinking about for a
while and what it says about our goals in education.
What are we doing that where we want people to learn we create an environment
to make active and curious people passive and non-curious?
I expected I would like teaching when I started. Since learning about Dewey
and his legacy and concluding that I would not lecture or give tests, I love
teaching. Most of my students say they've never taken a course like mine and
want to know how they can take more.
------
cafard
Diane Ravitch's book _The Uncertain Crusade_ has an interesting chapter on the
rise and decline of "progressive education." Dewey himself was not happy with
all that went under that name. Based on the little I have read of Dewey, his
model of a school demanded better and better-trained teachers than what it
aimed to replace. However, given how vaguely he wrote, he could hardly blame
others for misunderstanding.

I think this is our future, whether it's dystopian or not.
Technology is eventually going to make it impossible to really prevent
"Persistent aerial surveillance". What requires an expensive small blimp today
might become the size of a ping pong ball (or wide area flock of them) and
come out of a 3D printer tomorrow.
So who will be using such tech? Governments and private entities alike - we
can try to legislate against either but technology will probably overpower the
legislation quickly.
So what is the impact of this sort of technology? Maybe it's not all George
Orwell. Your bike was stolen on Third St at 1pm? Roll the video back or
forwards to know exactly where the thief is. Someone shot up a nightclub and
rushed out in a crowd? automated video analysis caught them.
Yes it sounds scary if it were a monopolized power, but eventually I don't
think government will be able to hold monopoly on it.

often you do risky things when not driving, I tell your ex where she can find
you at the club.

On the contrary, I think humans can't handle it, and are literally going to
drive themselves insane with machines.

You think people can't handle it but it's actually pretty close to the way
most people lived before urbanization brought anonymity to the masses. Now,
technological changes might eliminate privacy which would be unprecedented but
it's anonymity that's historically weird, not its lack.

Anonymity sure. We're talking about privacy. It's always been at least non-

That's not necessary. Also, lack of emissions would attract attention, and so
be counterproductive. But using shielded equipment in a shielded room, that
would be prudent for private work.

_> "Aircraft surveillance has become an indispensable intelligence collection
and investigative technique which serves as a force multiplier to the ground
teams," the FBI said in 2009 when it asked Congress for $5.1m for the
program._
Holy military state, Batman! It seems that the FBI has really taken to heart
the change in mission statement from "law enforcement" to "national
security"[1].
_> The surveillance flights comply with agency rules, an FBI spokesman said.
Those rules, which are heavily redacted in publicly available documents, limit
the types of equipment the agency can use, as well as the justifications and
duration of the surveillance._
Given the duration and location of these aircraft, it's very hard to see how
these aren't an illegal search, given the past few years of judicial
rulings[2][3]. It's become very clear that collecting movement data, even if
that movement data is public, requires a warrant. No wonder the FBI wants to
keep a layer of fake companies between it and these planes. Also, if you do
collect wide area data for a specific target, can you keep the wide area data
for use later on for another purpose?
I volunteer for an organization[4] that works with cities to adopt privacy
policies regarding the data they collect, receive, and share. To date, our
privacy policies have mostly been focused on disclosing how local offices are
sharing local data (license plate readers, stingrays, etc.) with the feds, but
now it seems we need to add sections about disclosing incoming data feeds from
the feds.

It falls squarely within California v. Ciraolo, which says there is no
expectation of privacy in anything visible from the air. It also common sense.
Any shmuck with a general aviation license can take up an ultralight and see
what he can see. So can the government.
Jones involved a trespass on the suspect's property. Totally different
situation.

shabble
Without knowing the details, it seems like they shouldn't really distil
'expectation of privacy' down a simple binary "could someone not breaking the
law observe them or not" test.
IMO, the efforts to which that hypothetical person would have to go should
influence just how much privacy a person could 'expect' to have. Otherwise why
do people bother putting up privacy fences around their garden, when anyone
could just fly over? Or hoist a camera on a stick?
The problem being that the more effort required to observe, the more confident
an ordinary person could presume to be unobserved.
When we have UAVs that can loiter around (in public airspace, of course)
random buildings and bounce laser microphones off the windows, along with
thermal imaging and gait detection of individuals at a price that is
affordable by average people, would that change 'expectation of privacy'?
As long as the tech is embargoed or ridicuously expensive, there's a distinct
skew where the government can afford it and Joe Shmuck The Reasonable
Individual can't.
In fact, the mere ability to continuously loiter for extended periods and make
recordings is probably beyond an individual who doesn't have refueling support
or additional friends in similarly equipped craft to change watches.

Video/Cell surveillance with a Judges order by the FBI (a NON-FISA Judge - the
FISA ones are Rubber Stamps) is how the process is supposed to work.
The article raises two deeply troubling points:
1) That they operate without specific Judges orders - this means that they are
pretty much Dragnets sweeping up vast swathes of information indiscriminately.
2) They are used to help in "disturbances" (by presumably recording Video &
Cell info?). So even civil disobedience is prime target for these flights.
The combination points to a major overreach by the Feds. The temptation to use
all that info in one way or another (Parallel Construction for e.g.) is too
great. Needs ACLU & possibly EFF to sue & the courts to shutdown this crap.

To me it makes sense that the FBI needs a fleet of surveillance planes for
investigations. It also makes sense that these aircraft carry civilian livery
to be low-profile (same idea as an unmarked pursuit car).
What seems f-ked up are the shell companies. Why not come out and say "we have
surveillance planes; we need them for investigations; here's how much money
we've allocated in our budget to operate them."
The FBI shouldn't need to hide this.

The FBI using front companies for aerial surveillance of suspects seems fine
to me; That's just doing their job of criminal investigation.
The worrying part is seeing their planes overhead for hours at a time, which
looks more like potential persistent surveillance, or a dragnet that sweeps up
hundreds or thousands of people into whatever video/cellphone recording
they're doing.

I'm a little confused about what you're trying to say.
Light googling indicates that this is an extant system that has been fitted to
aircraft since 2009:
"DARPA, working in partnership with the Army Night Vision and Electronic
Sensors Directorate, Air Force, Air Force Research Laboratory and National
Geospatial Agency, conducted its first test flights using the ARGUS system
last year [2009]."
The DoD indicates that the system was operationally deployed to Afghanistan in
Q1 2011. [0]
LLNL has an article describing the system's optics, technical specs, and their
work on processing the data streams it generates. [1]
BAE released an IR upgrade in 2010:
"BAE System's first flight tests of ARGUS-IR's predecessor, ARGUS-IS,
concluded last October aboard a U.S. Army Black Hawk helicopter." [2]

Thanks for the added info. I didn't do any googling; I limited my commentary
to the source you provided (I didn't look at the youtube video, that method
usually carries a low signal to noise ratio). The wikipedia article is light
on actual information about the ARGUS IS; the primary source is an article
with the title "drone nightmare" in it. Other advertised capabilities don't
exist yet. I will add your sources to the wikipedia article, they are much
better than what is there.
I don't think that it should be expected that I exhaustively comb search
engines to find support for your point; I think that it's reasonable that I
look solely at the source you gave me.
That said, I found the capabilities in your first (0th) source to be chilling.
That source definitely supports your point.

Honestly, unlike what the NSA is doing, this doesn't outrage me. Surveillance
aircraft only see what is visible from the air—primarily public spaces.
When I'm in a public space, I don't have any expectation of privacy. Heck, a
single private citizen intent on tracking my every move could easily "surveil"
me in this way.
If the FBI is only exercising techniques which a private citizen could deploy,
I really don't care. I fully expect that every minute I'm in public is being
documented—it's spying on private communications which really outrages me.

greatly impact the work they are doing. I'm definitely concerned about drones
taking over this work with better tech, but I feel like I should be up in arms
about these flights and I'm not.

Yes! There are even articles from 3013 about the FBI using small planes for

photos of the planes and their camera turrets.

The way they mentioned counter-clockwise orbits and then talk about FLIR's
newsletter mentioning left-handed patterns seems to be trying to use the
left/counter-clockwise aspects to connect the two.
That seems rather a stretch. Pilots have better visibility to the left in most
small planes, and so left turns are preferred. Also, propellers usually rotate
clockwise, which causes some biases toward the left I believe, which may make
it slightly easier to do left turns.

SILE indeed looks great, promising to come on par with the typesetting quality
we have come to expect since TeX: Knuth-Plass line breaking, Unicode and
OpenType font features support, complete with contextual shaping, Cassowary
constraint solver, parallel text, multiple apparati, foot and marginal notes,
vertical typesetting… This is a typographer’s dream!
But, like TeX and friends (LaTeX, ConTeXt, etc.), creating stylesheets and
document templates still looks like a pain with SILE and alike. At least from
the perspective of designers who have come to expect a strict separation of
concerns between document structure/semantics and its styling, and who are
used to work with a declarative stylesheet-based language like the prevalent
CSS, as opposed to the macros of TeX, and its document model which conflates
semantical markup with inline styling instructions.
Similar initiatives like SILE, which attempt to port TeX to newer languages
while untangling macro spaghetti, like Cló¹ and Rinohtype², didn’t consider
CSS-based stylesheets either. Which is a pity, especially with highly
developed W3C Working Draft open standard specifications³ for paged media
being out quite some time now.
That’s exactly what makes PDF formatters like Prince⁴, which accepts standard
html and css as its input, so immensely attractive: users can continue to use
the (Web) technologies they already know (html, javascript, css) and enjoy a
strict separation of concerns between document contents, templates and make-
up. Unfortunately, there exist no FLOSS alternatives.
Once in a while, people are coming up with the question whether there are TeX
flavors which do support `.css` as an input.⁵ Peculiar too that no project
exists to create a compiler to convert and map css style rules, selectors and
properties to something which TeX does understand. (Except may this⁶ one.)

What goes into writing a typesetting system like this? I know kerning is one
thing that is needed but I'm assuming there's a lot more then just spacing

Also this does look really good.
~~~
fusiongyro
_TeX by Topic_ was a much clearer resource to me than _the TeXBook_ although
one eventually has to go back and read that. TeX seems like a reasonable
approximation of it, but it's definitely slanted towards text-heavy and
mathematical stuff, which is pretty far from what something like InDesign is
mostly about. I'm just an appreciator, not an implementer, but this is my
overview of typesetting text:
First, you have to build words from letters; this is where kerning comes into
it.
Second, you have to build lines. TeX calls this "horizontal mode" and this is
where inter-word spacing and justification matter. TeX uses a "boxes-and-glue"
model, so during line building it's essentially putting stretchable glue
between each word, and then when the line is built, it spreads the space
evenly between all the pieces of glue to achieve justification. Glue has a
natural size as well as minimum and maximum values; this along with
hyphenation has to do with calculating the line "badness."
Third, you have to build paragraphs. This is what TeX calls "vertical mode."
Between each line of text, it inserts vertical glue that works similarly to
the horizontal glue mentioned above. Another glue is used between paragraphs.
TeX worries about widow and orphan lines here; other calculations are made to
prevent or allow them. This is like badness but I think it has another name.
Finally, you have to build pages. With TeX, this happens periodically as it
notices it has enough material (or you force it by calling the right kind of
eject). By default, this invokes a page building macro which you can
customize. This part of TeX feels pretty 1970s and hackish, but essentially,
there is a variable that contains a box with the supposed contents of the
page, your job is to assign a box to a certain location and remove some of the
contents of the input box. LaTeX's "float" mechanism is actually built _on top
of_ this mechanism, but as it's pretty procedural, you can certainly achieve
other effects here.
So that's the birds-eye-view I acquired a few years ago when I did some in
depth playing with TeX. First you build words, then lines, then paragraphs,
then pages. There are different considerations at each stage of that but TeX
attempts to subsume everything in that overall flow.
I think that process probably generalizes nicely for some things and is almost
inadequate for others. I'm not sure how ConTeXt achieves the grid layout; I
imagine they are relying on some complicated Lua code to pull it off, because
TeX really doesn't care unless you make it.
~~~

There's also _TeX: The Program_ that is a literate code for TeX. It's in
Pascal though and littered with literate macros, so it's rather hard to read.

I'd love beautiful typesetting on the web, where I actually write and read. I
don't use paper.
~~~
username223
Note that I use paper, because I am an old person. They're very different
problems.
In print, you have to deal with page breaks and positioning of figures, but
you know everyone will see the same thing. Doing this right requires human
attention, but you can produce beautiful layouts, even with multiple columns
and oddly-shaped text boxes.
On the web, everyone sees a single "page," but those pages are all different.
Even simple two-column justified text is mostly garbage on the web, and forget
trying to float figures close to their references. Web designers have mostly
given up, resorting to either huge margins, or an ugly wide wall of giant-font
text. Print-quality layout and typesetting on the web is very far away.
~~~
coliveira
Completely true, but for fairness the reason is that the web was not created
as a tool for text layout. The goal was exactly the opposite, to make the text
independent of layout and displayed differently in the different browsers.
Doing good text layout on the web is practically an intractable problem. On
the other hand, we already have software capable of doing this, such as PDF.
~~~
username223
I don't know if Tim Berners-Lee thought about layout. SGML was text with
semantic information, and HTML was text with cross-references. Back when
displays were tiny low-resolution things little better than terminals, and
most web pages were just text with a few images, layout didn't matter. It was
all ugly. Now that displays are larger than books, and pages are heavy enough
to contain the entire Gutenberg Bible, people are starting to care.
Maybe in 5-10 years, with enough server-side computing power and bandwidth,
sites will ask for the client's screen size and desired font size, then serve
an appropriate PDF.

> Is there really no way to get closer to normal performance for networking in

Unfortunately not! It takes many different tweaks, tunes, and hacks to squeeze
performance out of VirtualBox. To make matters worse, NPM as a tool is pretty
slow in general -- in fact it's become somewhat of a joke in the community[1].
npmserve solves this by offloading the work to a remote server, so the npm
install process becomes as simple as fetching and expanding a tarball.
> Also, why not use Linux VPS?
This is something we may move to if performance becomes an even bigger issue.
We use vagrant-aws[2] in our integration testing environment to achieve a
similar effect.
> Also, take a look at Docker as an alternative to Vagrant/Chef.
We don't currently use Docker (in this use-case at least). It's definitely an
option, though! Using Chef here is pretty handy, insofar as we can use the
same infrastructure code we use on production, so our developer environments
are as close to production as possible.
> Also, take a look at pnpm.
Nice, this is the first I've heard of this project. We looked at ied[3], but
we weren't comfortable moving over to it without also moving our production
infrastructure.

The root issue is clearly NPM's terrible performance, but it seems to have

Given that you're talking about developer environments, wouldn't it have been

Hakashiro
My issue with the term is that governments are, and will ever be more invasive
with our private data than private companies. This makes sense: the government
will never be held accountable for data hoarding, and in fact kinda needs to
hoard data to prosecute tax fraud and ensure law enforcement, but private
businesses want to make sure people still use them, even if their users are
privacy conscious.
Moreover, a bunch of fully for-profit companies are living off of exclusively
selling privacy. Their only reason to exist is protecting their customer's
information. Think ProtonMail, Tutanota, TunnelBear, privacy.com, the Mozilla
Foundation (to a certain extent), Qwant, DuckDuckGo, and so on and so forth.
I very much preferred the previous term: "Government Surveillance". As some
other comments on this page also pointed out, this loss of privacy comes with
the benefit of productivity and reduced friction, while government
surveillance rarely ever has a positive side to it (except catching criminals,
and even so at the expense of non-criminals' privacy).

Capitalism isn't seen as anything bad in most countries after the cold war.
I would prefer the term privacy prostitution or data prostitution. You sell
your privacy in exchange for getting "free" search, "free" news, "free" maps,
"free" email. Of course such services cannot be free of cost.
Traditionally Germany had a law that you are not allowed to give "gifts" when
selling something. So when offering a car they were not allowed to give a
"free" grill or something like that. The goal was to protect consumers from
intrasparent pricing and unfair business practices. Some market-liberalist
politicians abandoned the law many years ago, because consumers are "mature
enough" to make their own decisions.
So how many consumers decide to pay for the internet services they use instead
of being tracked?

> Capitalism isn't seen as anything bad in most countries after the cold war.
It’s called “surveillance capitalism” because companies are _capitalizing_ on
selling people’s data. It differentiates it from _government_ surveillance.
~~~
Fnoord
In a corrupt (nation) state, you could for example buy some information about
a person, via the government. Corruptcy is not a black-white definition. There
are a lot of shades, wheels in a machine, etc. So a state is not merely
corrupt, yes or no.

like sell services to the aforementioned governments, or sell your porn

bcaa7f3a8bbc
And practically, all the data collected by private corporations can be
obtained by governments via a subpoena. Until it could be changed, all
corporate surveillance is ultimately government surveillance. And there's
strong evidence suggests that it occurs at a routine basis. Although some
companies like Lavabit showed respectable efforts to be independent and
privacy-respecting, on the other hand, some companies actively cooperating
with the government, or even oppressive regimes without regards of ethics. So
yes, government surveillance is worse than corporate surveillance, but the
latter can be seriously harmful in many cases as well.

Barrin92
I listened to the Econtalk episode with Zuboff and Roberts a while ago and I
wasn't really sold on her arguments despite actually being personally quite to
the left on economic issues usually.
The problem I had with the critique is that the answer to surveillance
capitalism always seems to be a return to privacy. Big Business is to big, we
need to claim data autonomy,be democratic, and so on.
I think the reason why surveillance capitalism is so successful is because
people actually like the automation and transparency. There's always this
"wake up sheeple" element to the critique that in my opinion just doesn't
address the fact that people simply value the utility they gain out of these
tools higher than privacy. I think the better way forward is to align the
interests of end consumers and business rather than attempting to retreat back
into private spaces.
~~~
Fnoord
> I think the reason why surveillance capitalism is so successful is because

(I still have to read her book.)
They pay with their privacy, but the payment is not at all transparent. In a
way, it already happened: if you upgraded to Windows 10 for free back in the
days (before GDPR), you paid with your privacy. If you use Android instead of
iOS, you have a cheaper device, but you pay with your privacy. The Apple tax
is high in a lot of countries. Too high for the masses. In essence, an iOS
device is a status symbol that you paid with money instead of your privacy.
~~~
Barrin92
>but you pay with your privacy
And I think that's a perfectly okay choice to make. I don't know why I
shouldn't pay with my information, given that I'm aware of it. I'm fine with
having an android phone and using the few hundred bucks I save on something
else.
My information has some value, and by trading that information to a company
that provides me with a service I get something out of it. If I keep data
private that I don't mind sharing and instead would say, pay with cash, I'd
lose out on getting some value out of my data.
Now I think there is an interesting discussion to be had if users could
organise to leverage the value they get out of their data, people have talked
about a sort of 'data union' to collectively bargain for a higher return, but
in principle I don't mind using my data as a currency.

NAME
fmt - simple optimal text formatter
SYNOPSIS
fmt [-WIDTH] [OPTION]... [FILE]...
DESCRIPTION
Reformat each paragraph in the FILE(s), writing to
standard output. The option -WIDTH is an abbreviated
form of --width=DIGITS. Mandatory arguments to long
options are mandatory for short options too.
-c, --crown-margin
preserve indentation of first two lines
-p, --prefix=STRING
reformat only lines beginning with STRING,
reattaching the prefix to reformatted lines
-s, --split-only
split long lines, but do not refill
-t, --tagged-paragraph
indentation of first line different from
second
-u, --uniform-spacing
one space between words, two after sentences
-w, --width=WIDTH
maximum line width (default of 75 columns)
-g, --goal=WIDTH
goal width (default of 93% of width)
--help display this help and exit
--version
output version information and exit
With no FILE, or when FILE is -, read standard input.
~~~

One simple way would be to start teaching consumers about solar energy and
perform an energy audit on their homes. Scale that up to big businesses if you
want to charge more - however a sound knowledge of the local electrical code
(and standards) is necessary if you want to do the energy audit properly.
Use the findings of the energy audit to propose an energy plan. Partner with
an electrical supplier to re-sell solar panels to your clients
