Using Pseudo-URIs with Microservices - pcalcado
http://philcalcado.com/2017/03/22/pattern_using_seudo-uris_with_microservices.html
======
jamiethompson
What's wrong with using UUIDs for microservice architectures?
~~~
kuschku
As mentioned in the article, they make it hard to identify the type of
resource.
~~~
AdieuToLogic
URN's[0] can support resource categorization so long as the Namespace
Identifier (NID) does not collide with the reserved ones (and I'd throw in
those which are well-known in the industry as well).
So, for example, a URN which uses UUID's to satisfy uniqueness yet still
allows for categorization could look like:
urn:some-company:resource-type:abcdef012-3456-...
For complete technical conformance, the "some-company" NID would need to be
requested/registered from the IETF.
In practice, my opinion is that the registration step is largely not required
if the URN's are used strictly as an implementation detail within a system.
However, those publicized and/or having a reasonable chance of being persisted
by an external actor should have a sufficiently unique NID such that it can be
registered and, more importantly, does not have a coincidental collision with
other systems generating URN's.

Imo, this is a great combination of strategies when you want to keep people
away from iterating. It also gives you the basis for a decent ACL system.
Yeah, you use a few more bytes per item, but modern DBs can handle that.
Probably worth having a autoincrementing ID on tables using uuids as well,
though. Not 100% sure on that, but I've definitely hit batch jobs that need to
run / frameworks that require autoincrementing integer IDs, and getting stuck
is a pain. (Adding an autoincrementing key after the fact is doable, but at
least on postgres involves a rewrite the the entire table, so you kill the
heck out of replication)
~~~
AdieuToLogic
Probably worth having a autoincrementing ID
on tables using uuids as well, though.
Quite true, IMHO. I usually define both an auto-incrementing integral primary
key (PK) as well as a unique string column for the URN. The PK is used for
deletes/updates/joins/referential integrity and is never exposed beyond the
server processes.

One important thing to remember with taking this approach is that you can work
yourself into a huge bind if you store the mapped-versions in logs/other
persistent storage and end up needing to change formats later. Say the
original mapping version is based on 32 bit integers, or is cryptographically
signed and your keys get exposed. If rolling the functions means you can no
longer identify objects from logs / in databases, that's a huge problem.
That means things like access logs will no longer map to their respective
current versions unless you keep around two separate encoder/decoders and are
able to guess which version you need all the time.
It can become a big, unfun problem pretty fast.
~~~
pcalcado
That's a great point, thanks.

NathanKP
Personally I've always favored a JSON HATEOS approach with my API's, where the
JSON response contains the actual URL's of the resources referenced, not just
URN. Example from one API that I maintain:
[https://changelogs.md/api/recently-
crawled/](https://changelogs.md/api/recently-crawled/)
One major advantage of this is that it allows clients to be built which have
no hardcoded URL's at all (other than perhaps the top level URI that gives
them the list of URL's that the API exposes). This allows the API maintainer
to adjust resource paths retroactively, in addition to just exposing an API
that is easy to explore.

I was not aware URN was deprecated... Is there a reference somewhere to these
recommendations?
~~~
dragonwriter
The use of the _name_ URN in the broad sense of "a URI that specifies a name"
is deprecated in favor of the general term URI (similar to the way that the
term URL is deprecated in the same source) per RFC 3986.
The use of URN for a specific URI scheme that provides names, for which there
is a global registry of namespaces to ensure uniqueness, etc.—which is what
the article discusses—is in now way deprecated. The author seems to be ill-
informed on the point which apparently is the only stated reason for not using
the internet standard that directly applies to the use case.
~~~
dragonwriter
It occurs to me that there is another possible interpretation: the reference
to URN being deprecated may have been a distorted reference to the fact that
IETF has identified a number of issues with the URN spec and some existing
registrations and other related issues and has an active workgroup and working
draft on an updated spec. It's hard to tell if that's what was intended,
though, since the dismissal was so terse; if so, a discussion of the issues
with existing URN spec that are specifically problematic for the use in
question would be nice, as would more description of why you aren't using
_actual_ URIs with a custom scheme rather than pseudo-URIs (since real URIs,
whether URNs are not, mean that tools supporting the standards can be used,
rather than building custom tooling and libraries for your almost-but-not-
quite-URI setup.)
Whatever the URN reference is intended to mean, this seems to be custom-over-
standard with less clear justification than I would want for that choice.
~~~
pcalcado
Author here.
The deprecation comment refers to this:
[https://tools.ietf.org/html/rfc3986#section-1.1.3](https://tools.ietf.org/html/rfc3986#section-1.1.3)
we had been using URNs and URLs the old way.
But in any case the fact that we're having this conversation I had had to dig
up some RFC from 2005 reflects the _actual_ reason for not following any
specific standard: I perceive them and their specifications to be confusing
and full of historical context that has changed over time. Assuming that there
are no other benefits to using the URN scheme specifically (maybe there are
and I am not aware of them?) I'd rather use a simplified URI and custom
schemes.

Curious if tag URI was considered
[https://en.m.wikipedia.org/wiki/Tag_URI_scheme](https://en.m.wikipedia.org/wiki/Tag_URI_scheme)
~~~
DorothySim
Is there a benefit of using tag URI instead of a regular old URL? E.g.
tag:blogger.com,1999:blog-555 vs
[https://blogger.com/1999/blog-555](https://blogger.com/1999/blog-555) The
only difference I see is that URL should point to something (can be referenced
in a browser) which may or may not be an additional benefit.
~~~
pacaro
I worked on a project that used "regular old URL" just like you suggest, for
contract and service identifiers, which needed to be human
read/write/generatable
Tag URIs would have been better because:
a) not everyone owns a domain, but tags allow email address as authority
b) it's confusing to many people to overload http URIs this way
c) as a contract identifier the URI doesn't need to point to anything, but
this creates cognitive dissonance — this is probably part of b)
d) too damn long — tag URIs might suffer from this too. We were using these
all over the place and there's no good way to truncate them
~~~
DorothySim
a) is particularly interesting to me. I thought about giving people ability to
create their own namespaces and used
[https://user.example.com](https://user.example.com) or
[https://example.com/user](https://example.com/user) as a namespace but tag
URI looks cleaner.
By the way why did you need human readable IDs? I'm asking out of curiosity
because there is certain charm to just using UUIDs everywhere (and urn:uuid).
~~~
pacaro
There were some places, where only machines would interact with them, that we
used urn:uuid. But we had UI, code, and log files etc, where developers needed
to interact with them too

Show HN: Grid.js – Advanced table library that works everywhere - afshinmeh
https://gridjs.io/?hn
======
afshinmeh
Hello folks :wave:
I’m Afshin, the creator of Grid.js.
Grid.js is an open-source table library written in TypeScript and published
under MIT license.
My goal is to develop a framework agnostic table library that:
\- Works everywhere. You don’t need a specific framework to use Grid.js
\- Lightweight and easy to use
\- Fully documented and tested
\- Developer friendly. Grid.js is written in TypeScript! Supports all modern
web browsers
Please take a look at the examples ([https://gridjs.io/docs/examples/hello-
world](https://gridjs.io/docs/examples/hello-world)) section and let us know
if you have any suggestions.
Although Grid.js is currently designed to work with web-browsers, I’m actively
thinking and working on adding other integrations like React Native (see
[https://gridjs.io/docs/philosophy](https://gridjs.io/docs/philosophy))
Please let me know if you have any suggestions or comments. Happy hacking!
:computer:

I'm playing around with it in an Observable notebook here:
[https://observablehq.com/@simonw/grid-js-with-

Any idea why the columns aren't displaying correctly for wider tables? Take a
look at this example:

Oh great! I guess the columns are not properly rendered because there are a
lot of columns. That looks like a bug to me. I just created two issues and
will release a bug fix soon.
Thanks!
~~~
robertlagrant
> Oh great!
The correct response :-)
------
Bishonen88
Good effort! I'm not sure how 'advanced' it is though. I'd even go as far as
call it 'simple'?
E.g. the following features would be required to make it advanced (list not
complete):
\- Export data (csv)
\- Align columns based on their content
\- Tree data (parent/child rows)
\- Total rows
\- Formatting applied based on data type (currency, numerical etc.)
\- Reordering columns
\- Resizing columns
\- Hiding columns
\- Optional filter field for every column
\- Conditional formatting
\- Tripple Sorting & Multiple sorting (sort by more than 1 column at a time)
\- ... more
In the react world, I found this to be a good foundation for an 'advanced'
table. Since it's rather inconsistently developed, I ended up forking it for
myself and working on my own copy, removing unneeded elements and enhancing
with everything else I do need.
[https://material-table.com/](https://material-table.com/)
~~~
afshinmeh
Thanks for your feedback.
I agree that Grid.js is not a full-featured plugin _yet_ and it's still
missing essential features, like those that you mentioned but please bear in
mind that:
\- I have only released the first version of the library.
\- I have been focusing on fundamental blocks of a lightweight _data
processing_ library (see: [https://github.com/grid-
js/gridjs/tree/master/src/pipeline](https://github.com/grid-
js/gridjs/tree/master/src/pipeline)). That's what took most of my time.
\- Grid.js is framework agnostic which is a bit different compared to other
libs
The pipeline is very easy to extend and I'm confident that most of those
features will be added soon.
~~~
Bishonen88
I don't doubt that you can and possibly will make this a great library. It
seems like a nice and clean foundation for one. I just commented on the word
'advanced' in the title. You admitted yourself that it's missing essential
features, so advanced might be an adjective you'd want to use for release 2.0
;)

How accessible is Grid.js? The main differentiator between table libraries for
me these days is accessibility. Many libraries and frameworks out there do it
poorly. The better ones are often tied to company-specific frameworks.
From playing around a bit, I've at least noticed that sortable headers have no
focus indicator, the "sort column ascending" text gets included in the
column's accessible name, and un-sortable column headers are read as clickable
by screen readers.
I would LOVE a framework-agnostic table library that's both lightweight and
fully accessible. If there's a chance for Grid.js to take this in its
philosophy, I would be all in!
~~~
nohuhu
> The better ones are often tied to company-specific frameworks.
That is because to implement accessibility in a grid/tree widget to a
meaningful level, you need _a lot_ of underlying code. Even in modern
browsers. Source: implemented accessibility in Ext JS framework.
One of the most often asked questions from users of Ext JS was: hey, can we
have the Grid widget without all the bloat? Sure, and ~95% of the framework
exists so that the Grid can have its features and work reliably across all the
browsers. You can probably do without the rest 5%, no biggie.

I'd say the claim "works everywhere" does not consider small screens. I had a
look at the examples with Android Chrome in portrait viewport, and cell
content gets either cut off with ellipses on overflow, or breaks long words
such as email addresses unintelligibly over several lines.
In my opinion, scrollable-by-touch tables such as Bootstrap 's "responsive
tables" fix these issues. Add "scroll for more" shadows for even better UX.
------
rootcage
Out of curiosity how is this better than current Grid/Table implementations?

\- Grid.js is a data-processing pipeline (see [https://github.com/grid-
js/gridjs/tree/master/src/pipeline](https://github.com/grid-
js/gridjs/tree/master/src/pipeline)) which enables you to easily extend the
library \- It's framework agnostic! \- It is written in TypeScript \- Fully
tested and documented

Does anyone know why HTML tables can't natively support a lot of common table
functionality? Lazy rendering, fixed column headers, sorting and so on? Are
there any proposals to add all this natively?
~~~
orange8
I think a bit part of HTMLs success is not being too opinionated about more
advanced/specific UI components. Think of it more of as a low level GUI
toolkit constructor, one to builg actual GUI toolkit on top of, for example
material-ui and bootstrap.
~~~
Zecc
That doesn't really answer the question though.
It's up to the browser implementers how they do tables, and they certainly
could go ahead and cater to common cases in this area. As user agents, it's
the browsers' job to be helpful to the user regardless of what the HTML looks
like.
For example, nothing in HTML talks about having a search prompt appear on
Ctrl+F, yet everyone does it.
~~~
orange8
HTML does not have a table component because it is a markup language, and that
kind of interactivity (sorting, filtering, pagination etc) is really beyond
its scope. The exception to this are basic user input fields (buttons, check-
boxes etc).
This is by design, browser vendors are focused on implementing low level APIs
and functionality, leaving the higher level component development stuff up-to
web developers and designers.
Use a combination of JS, CSS and HTML to create advanced components from
scratch, or use one of the thousands of open-source libraries available. The
library linked to in this post is a good example of that.
> It's up to the browser implementers how they do tables, and they certainly
> could go ahead and cater to common cases in this area.
They already have, via the <table> tag ([https://developer.mozilla.org/en-
US/docs/Learn/HTML/Tables/A...](https://developer.mozilla.org/en-
US/docs/Learn/HTML/Tables/Advanced)).
------
rkagerer
This looks really cool although I find it disheartening that we need to resort
to JavaScript simply to construct a decent table.
~~~
huhtenberg
You are trolling, mate.
Obviously nobody NEEDS to resort to that. However there's a difference between
... simply to construct a decent table.
and
... to construct a decent table simply.
which is what this lib is for.
~~~
rkagerer
Nice distinction! Although I'm not sure "trolling" is a fair dig. My comment
was genuine.
When I wrote my first HTML page you could make them out of basic <TABLE> tags
and nobody would beat you over the head with a styleguide for doing it wrong.
I found them approachable if you followed some basics like avoiding nesting,
and with care, dynamic sizing went a long way. But I understand some people
are zealously against them (for good reason). CSS addressed several of the
shortcomings but introduced new complexity and gotchas. My frustration is that
instead of evolving to simple, elegant and approachable syntax, we landed in a
place that calls for a library to patch in those attributes on top. (And now
I'm greeted with bank statements that dynamically add content as you scroll,
making it impossible to cut and paste the data from a spreadsheet).
None of that takes away my admiration for the author's work, I'd just prefer a
world where the hole filled by this library didn't exist in the first place
:-).

Looks great! Any plans to support SSR in say, the React use case? useEffect
won't run on the server and obviously you don't have the DOM.
I'd love to use this for the table to come rendered from the server then
hydrate on the frontend and enable AJAX pagination, etc.
Completely understand if you can't, after all, you'd likely need to more
tightly integrate with ReactDOMServer.

That makes sense. SSR should be possibly and relatively easy to achieve. I
will create a ticket.

mason55
One of the issues we find is that as the number of rows/columns in a table
grows, the performance of native browser tables just craters and you have to
fallback to your own rendering engine using <canvas> elements.
Have you pushed the rendering performance at all to see how far you can get
without scrolling getting painful or seeing tearing artifacts?
~~~
mstade
How many columns/rows can you realistically fit in screen? Isn’t this
practically solved for most use cases by just having as many as needed for
rendering and replacing contents as necessary?
I’ve worked in financial institutions for going on a decade at this points and
there are grids everywhere. I’ve learned a thing or two about them in these
years and that’s:
\- everyone wants to implement their own, for reasons
\- they’ll mostly do a decent but not quite good job at it, because it’s
complicated and oh hey let’s just all forget about accessibility (traders love
keyboard navigation!)
\- performance is always a problem till someone reinvents virtualized row
rendering
\- excel beats your thing anyway and everyone knows it so if you just have
decent excel import or even just good paste handling you’ll do fine
\- 99% of grids people actually use never show more than two dozen rows or so,
and then implements pagination and just like with google no one ever goes to
page 2 of the results
If you have a pressing need to handle thousands/millions of rows, it’s likely
not for display but for editing, in which case:
1\. Just use excel
2\. Virtualized rows still has your back, ain’t no screen showing more than
maybe a hundred rows or so anyway, and even if it did no one reads that far
Grids really feel to me like a rite of passage for front end developers, along
with a basic charting library and mildly interesting application framework.
Incidentally, this is also how I’ve landed most of my jobs, so maybe I’m
biased.
EDIT: This is by no means a dig at the author and I’m sorry if it may come
across as such! This library looks like a fine piece and I wish you every
success!
~~~
at-fates-hands
>> Grids really feel to me like a rite of passage for front end developers,
Agreed!
The last two jobs I interviewed for the code challenge was a) hit this API
endpoint, b) pull the data and put into a table and c) make said table
responsive and accessible.
The majority of front-end work these days is either forms or tables. Get good
at both and you'll have steady work forever.

You’re right, I forgot about forms – good shout!

What's the "Advanced" part in this ? Vue/quasar tables already provide
extensive functionality and I am sure there are react and angular
alternatives.
I don't think there is a need for a library to work across vue/react/angular
at the same time because no single person is going to use those in a single
project.
I appreciate the project since I am frequently looking for js grid
implementations but what the differentiator here ? Is it performance or
styling or flexibility or just variety of frameworks ?

and lazy-loading will be added in a week or two.

High level programming languages automated assembly language programming, by
the way. Generally speaking. For instance, with the use of a high level
programming language like Python or JavaScript, the operator or user does not
need to be concerned with the management of computer memory or processor
registers (notwithstanding the fact that such low level abstractions differ
between processor architectures as I'm speaking generally).
So even software development is susceptible to the phenomenon of automation.
Anyone got any examples of other kinds of automation?

A Flurry of Copycats on PubMed - beefman
http://blog.thegrandlocus.com/2014/10/a-flurry-of-copycats-on-pubmed
======
jldugger
A friend of mine reached out to me via LinkedIn several months ago, stating he
could probably use Tableau and some public datasets to DDoS the medical peer
review system and earn tenure at the same time: low impact factor * a million
is still going to be a lot better than the alternative. Sadly, I didn't hear
anything terribly insightful when I asked him about spurious correlations and
data mining as a perjorative term, so I left that one alone, and I assume he
doesn't have the balls to go through with it since you know, there are actual
people in the tenure committee who have to review your CV.
One angle that isn't quite clear to me from the article; if you build a system
to harvest datasets, find correlations, and push them through a set of
templates with conditional subtemplates based on saliency, with correct
citations of source data to produce a single article, is it wrong to put your
name on it? And if you do 30 of them?
Obviously selling your naming rights to papers harms both the community who
might wish follow up with the authors on scholarship, and those who use peer
reviewed publications as a filter. But I think the real lesson here might just
be that abusing the university administration's institutional data analysis
platform to game your tenure case seems like a waste of time in comparison to
selling one weak article a day for 10,000 bucks.

Though I use PubMed frequently, can't say I've encountered "copycat" articles.
It's disheartening to find out what has been happening, but perhaps not a huge
surprise to the extent publication becomes merely a commodity to accumulate in
order to further an academic career.
It does prompt me to keep an eye out for such occurrence. But I'm pretty sure
not every researcher goes about things that way. Maybe it depends on the field
of research. The topics of interest to me could simply be too obscure to
attract that kind of attention.
Sure seems if anything can be done with computing technology, it will be done.
What sort of future awaits us? We humans always seem to do until we overdo
then redo it all over again, it doesn't ever end.

Traster
Between the breadth of their investments and the favorable terms they can get
due to their size and positioning it seems very unlikely they'll significantly
under perform the market in the long term. Quite literally, they're so
diversified it seems very unlikely that they can completely burn the money.
It seems unlikely for them to outperform, but I don't think it's likely that
they'll be notably underperforming.
~~~
hodder
Define "the market". They are diversified across the "new tech" sphere, which
on average produces mostly losers and a few big winners.
Diversified tech funds or VC funds as a category, which mostly ignore the
large cap and mega cap sphere, have historically underperformed the market
except for a group of elite VCs.
What this means for Softbank remains to be seen, but the very act of dumping
this much money indiscriminately into new tech cos may have juiced valuations
to the point of hindering future returns on the basket.

We somehow managed to make it work, can’t exactly remember the details but I
think at some point it involved us sending them desperate emails (or maybe
phone calls, can’t remember exactly) asking them to please change some
settings on their side of things so that we would be able to test as close as
possible to “live”, it took them at least two or three days if not more to
make the change, which created unwanted dead time for us.
To say nothing of the fact that at some point we spent at least two days
practically hitting a wall over and over again: we were sending the requests
exactly as their not-so-great docs were telling us to do but the response was
totally different from what we were expecting. In desperation we somehow
managed to contact them (meaning my boss sitting on a phone call with them) to
realize that the dev instance they had provided us with still needed some
small change on their side of things. Totally non-transparent framework and it
all seemed as fickle as a castle made out of sand.
For comparison we had the best experience implementing Stripe, it was like
night and day compared to Vantiv. Unfortunately at the end of the day you need
to implement what the stakeholders want.

opportune
You're comparing the total value of all housing to GDP vs. an actual percent
of GDP. That's not an apples to apples comparison.
A quick lookup tells me construction is about 4% of GDP. And
financing/ancillary services for that construction, if I had to estimate,
might make up another 2% at most. Which is pretty close to tech
~~~
T-A
Yes, but what happened in 2008, and caused the crisis referred to by rapsey,
was that housing lost a large fraction of its _value_. It was not a drop in
construction, financing etc that tanked the economy; it was the loss of value,
which left a giant hole in balance sheets.
The apples-to-oranges comparison was introduced by rapsey, I merely provided
the numbers.

Interview with Alan Kay - gits1225

======
bcantrill
Alan Kay is a brilliant guy, but I really wish he could open his mouth without
shooting it off. In particular -- to speak to my own domain -- he bleats about
"feature creep" in an operating system with absolutely no demonstrated
understanding for a modern OS. Is KVM "feature creep"? Is ZFS? Is DTrace? He
shows not so much as an ounce of understanding for why these things exist or
empathy with those for whom they were created. I have great reverence for
history (and Kay and I share an intense love for the B5000[1]), but I also
think it's a mistake to romanticize the past. Viz., when he wistfully recalls
the Unix kernel having "1,000 lines of code", he can only be talking about
Sixth Edition: even by Seventh Edition (circa 1979!), the kernel had
(conservatively) over ten times that amount.[2] And this is still a system
that lacked a VM system and TCP/IP stack -- and tossed if you created the
151st process![3] If he wants to criticize the path that history has taken,
fine -- but when he is so ignorant of the specifics of that path, it's very
hard to treat him as anything but a crank, albeit an eminent one.

Cranks don't really put their money where there mouth is. If you haven't seen
it yet, I'm sure you'll enjoy looking at the STEPS project:
<http://www.vpri.org/html/writings.php>
In summary, the goal is a user-facing system in 25k SLOC, from kernel to GUI
apps, including all the code for compilers for the custom languages they made.
They call the languages "runnable maths", or "active maths", where they think
of a minimal notation to specify how a system should behave, and then
implement a compiler to run that notation as code. They manage this through a
compiler-writing language, ometa.
For example, to implement TCP/IP, they parse the ASCII tables from the RFCs as
code. Seriously, they just take it as is, and have a compiler to run it as
code. The implementation is supposed to be around 200 LOC (includes the code
written in Ometa for their compiler).
There's also a graphic subsystem, apparently with all the functionality of
Cairo (which is 20k LOC) in about 800 LOC.
Crucially, all this code is supposed to be very readable. Not line noise like
APL. The expressiveness comes from having custom languages.

This style seems amazing, but I haven't seen any tutorials for people
interested in learning how to do this themselves.. do you know of any such
resources?
~~~
pmb
They are doing the real deal thing - for each problem, designing a language in
which to express the solution, and then writing the solution. Part of the
point is that the building such solutions isn't really teachable in the
context of a tutorial. If a tutorial can teach it, then it's probably a pretty
shallow skill, and shallow skills should get designed away into a solution-
oriented programming language, and any tutorials for THAT language, etc etc...
The language they use to do that (O-Meta) is then a language-defining
language, and designing THAT means balancing on a level of abstractions that
is at least three levels deep, and each of those abstraction levels is hard
and necessary. They achieve great simplicity by thinking damn hard.
On the other hand, the mailing list (as noted by the other respondent) is a
pretty interesting place with few flamewars.

I see no rational way of telling for sure, as there are too many

built on _cooperation_ , and it seems to me to be the real driver of strong
innovation. Another lucrative social website is _not_ "strong innovation", but
a new research algorithm that pushes the boundaries of what we can do, is. One
is driven by profit, the other by curiosity. One happens because of
competition, the other because of cooperation.
~~~
paulsutter
Academia is rife with competition. As they say, the battles are so fierce
because the stakes are so small.
The open source community and Wikipedia are great examples of cooperation.
The biggest advances in business are usually by people who are completely
focused on customer needs and ignore competition (google up until their
google+ fascination, Elon musk, apple prior to android's success. Note how
google hasn't made any advances from their competition with Facebook, and how
Apple hasnt advanced the iPhone much since they started competing with
Android).

ehsanu1
Not the GP, but the quote gives undue importance to a number of websites that
have been successful. You have to consider whether some early software (say
Unix and the C compiler) was more instrumental to the transformative effects
of software on humanity, or say the software written Xerox PARC, or the
original TCP/IP work.
~~~
chris_wot
It depends on your measure. It could be argued that it's not undue weight as
these sites have impacted on such a massive proportion of the world's society.
For instance, gcc and unix didn't allow for the sort of direct communication
that twitter caused - look at the Arab Spring for example.
That the technologies you mention enabled the websites mentioned is not in
doubt, but without the websites and related technologies would things like
TCP/IP and Unix have had such an impact?
~~~
chris_wot
Seems that my comment is controversial as someone has voted me down. I'm
curious to hear from opposing views - I love technologies like TCP/IP, gcc,
Unix, C, etc. - but I think they wouldn't be much use unless they were used to
enable applications like Twitter, Google, Nethack and Wikipedia.
I do want to clarify that I'm not saying that the underlying technologies
aren't amazing.

I fully agree with him.
The web was designed for reading documents not to try to shoehorn an operating
system into the browser.
Thankfully the mobile world is bringing back the desktop applications concept,
while using the network for communication protocols as it is supposed to be.
~~~
dan-k
That's the exact opposite position from what Kay said:
"...what you definitely don't want in a Web browser is any features.... You
want to get those from the objects. You want it to be a mini-operating
system..."
Essentially he's saying that the way we think of browsers is holding the web
back. We could have collaborative WYSIWYG editing of Wikipedia or blogs, for
example, but instead we're stuck with just reading documents.
Perhaps it would be correct to say that the web was designed for reading
documents, but it shouldn't have been (at least according to Kay).

English is not my primary language, so I'm not 100% sure I understand what
you're saying, but in case you're suggesting that I'm full of what will turn
out to be empty rhetoric then of course that you have the right to your
opinion.
Anyway, I find it crazy that a guy like me (I think I'm in HN's bottom bracket

Why is the title of the post renamed? Should the titles be boring and dry
instead of being informative one line summary of the article that people may
find interesting enough to read it?
Look what happened to the previous submission of the same article here on HN:
<http://news.ycombinator.com/item?id=4224966>. Such a good article went
unnoticed because the title was plain unattractive.
Can we have a little bit of 'submitters freedom' here?
P.S: Original title was: "Internet by Brilliant minds, Web by Amateurs,
Browser a lament"

I actually think it was a good rename. He said a lot more than that, and
sensational titles aren't really needed on HN.

gits1225
I do agree on 'cheap' sensational titles, but I don't think mine was. I think
it was a better title more in-line to what Alan Kay _emphasized_ in the
article, giving it a bit of context to interest someone to read a great
interview, instead of just a generic 'Click Here' like the previous
submitter's, leading people to think it was not worth 'clicking through'.
~~~
chris_wot
Fair comment - on further reflection I agree, the title was reasonable as it
highlighted the emphasis placed by Alan Kay. It wasn't the title that was
sensational, it what Alan Kay said in the interview. Apologies for suggesting
otherwise!

Browsers were built around the idea of web pages, not web apps. The security
model works for web pages but precludes powerful web apps. There needs to be a
way for a user to grant UDP, TCP or POSIX power to a web app, because
WebSockets are not TCP, and IndexedDB is not POSIX and never can be. Just UDP,
TCP and POSIX and we're done. Let the community build everything better and

If the web had proper time to incubate without the pressures of the dotcom

"You can't go to heaven unless you're baptized." Actually, no. Perhaps if you
are Roman Catholic (and even then that's questionable); Evangelical Christians
either believe that you don't do anything to get to heaven and Jesus saves
you, or you choose to believe that Jesus Christ died as one perfect sacrifice
for the forgiveness of those who follow Jesus.
You may not agree, but I'm pointing out that the statement by Kay is pretty
inaccruate.
~~~
jorangreef
There are many interpretations of what it means to follow Christ. The rational
interpretation is Christ's own interpretation, the historical gospel story,
from the beginning of the Old Testament right through to the end of the New
Testament. The Scriptures are historical, they provide the facts of the
events. Thankfully they are also theological and interpret the meaning of the
events. Did it happen? What does it mean?

Fundamentalist radical literalist Christian here :) It's simple: when Jesus
and two thieves were being crucified together, he told one of them that he
would see him in paradise that day. Ergo, baptism is not a necessary
requirement of getting to heaven.

I haven't read too much Alan Kay before, but this interview made me realize
that he's not really the inventor of object-orientation as we currently think
of it. He says as much directly in the interview:
"And that's true of most of the things that are called object-oriented systems
today. None of them are object-oriented systems according to my definition.
Objects were a radical idea, then they got retrograded."
It sounds like his conception of "objects" is a more user-facing thing; an
object is something you see on your screen and can interact with and
manipulate by programming. This view blurs the line between users and
programmers. I'm not sure this is a terribly realistic model for how normal
people want to interact with computers. For all his disdain for the web, it
has succeeded in bring content to over 2B people worldwide, most of whom
wouldn't have the first idea what to do with a Smalltalk environment.

_I haven't read too much Alan Kay before, but this interview made me realize

Alan Kay is really the inventor of object-orientation. But when the concept of
"type bound procedures" was added to compiled languages like C (making it
C++), they called it object-orientation, even though type bound procedures are
a different thing than object-orientation. Real object orientation is about
sending messages between objects, those messages do not have to be predefined,
they are not dependent of type hierarchies, they can be arbitrary, they can be
relayed, ignored, broadcasted etc. You do not need classes or types at all to
be object-oriented by Kay's definition.
~~~
haberman
Nothing you said contradicts my comment at all. I said "he's not really the
inventor of object-orientation _as we currently think of it_." What we
currently think of as object-orientation is not what he invented. I don't see
what's controversial about this, since he said exactly this in the interview,
and I'm not understanding the downvotes to -3. The second part of my comment
was expressing basically the same sentiment as this comment, which was not
downvoted into oblivion: <http://news.ycombinator.com/item?id=4229788>

Which misrepresents his contribution rather badly.
~~~
haberman
From the interview:
KAY: We didn't use an operating system at PARC. We didn't have applications
either.
BINSTOCK: So it was just an object loader?
KAY: An object exchanger, really. The user interface's job was to ask objects
to show themselves and to composite those views with other ones.
BINSTOCK: You really radicalized the idea of objects by making everything in
the system an object.
KAY: No, I didn't. I mean, I made up the term "objects." Since we did objects
first, there weren't any objects to radicalize. We started off with that view
of objects, which is exactly the same as the view we had of what the Internet
had to be, except in software.
I realize that objects in Smalltalk were not all graphical, but this concept
of objects as graphical entities seems to be near and dear to his heart.
~~~
Ralith
The interview does not discuss Kay's contributions in any depth. You have
misunderstood them as a result of making weak inferences and not doing any
further research.
~~~
haberman
You're right that I don't know his work that well and probably extrapolated
too much from this interview. I just get a little irritated at people (even
smart, famous people) who criticize successful projects like the Web or
Wikipedia for not being good enough, or inferior to their own work, without
acknowledging that their success in the marketplace shows that they must have
done _something_ right.
I'm glad he's working on STEPS; I'm eager to see him push the boundaries of
what is possible, and if it succeeds, it will validate his ideas. But
Smalltalk and Squeak have been around for decades, and yet the Web and
Wikipedia are orders of magnitude more popular. So why does he have to bash
their creators as "amateurs" or "lacking imagination" when their ideas have
caught hold in a way that his work has not? What does he have to back up this
criticism? Sure, a lot of the ideas from Smalltalk and his early work on
object-oriented design have influenced other programming languages, but he
himself says that the way in which object-oriented design evolved runs counter
to his vision, not in support of it.

Hit testing for arbitrary paths on the iPhone - baroova

======
ajg1977
This approach seems really dumb to me.
1) Testing rectangles against paths is an easy thing to solve on the CPU.
2) On the first iPhone models if you're doing anything graphics related the
bottleneck is likely to be the GPU, so why give it more work?
3) Having the GPU rasterize into a user surface (which by definition must be
available immediately) is going to cause an ugly stall as you wait for the
drawing pipeline to be flushed. (no lock semantics in core graphics).
4) Having the CPU block on results from the GPU mid-frame is one of the worst
things you can do in architectures that feature graphics acceleration.

Where even Walmart won't go: how Dollar General took over rural America - devy

Just walked through a Dollar General store today while waiting for lunch. They
make Big Lots stores feel like Nordstrom.
If you are struggling I can see the appeal of the "low prices" but the value
of what you can get there isn't so great.
~~~
Fjolsvith
True, also the packaging is slightly smaller than in regular stores. E.g.: 7
oz cans instead of 8 oz cans. But the price is just enough less than the 8 oz
size price to make the consumer feel they are getting a good deal.

Waterluvian
Is rural America declining, or simply not improving the way the rest of
America is in the last 100 or so years?
~~~
sj4nz
America is developing in exactly the way the systems we like to use dictate
they should grow.
Here it is a transportation issue--in the opposite way you might think. Older
towns in the mid-west are spaced apart roughly 6-miles because you would only
be able to travel by horse about 20-miles in a day. Naturally, you would want
to be able to do "things" in the next town so you don't travel the entire day
just to turn around and go back home. So, towns spread out about 6-miles and
slowly grow. Bigger towns grew faster and smaller towns stayed the way they
are. Bring in interstates and railroads and suddenly some towns, if they had
nothing "going for them" never grow again or shrink--they're completely
bypassed.
People leave town for the opportunities, so opportunities have little need for
these towns except for the occasional externality: e.g. a massive chicken
processing or pet-food rendering plant no one wants to live near.
Dollar General has found a dirt-easy strategy and picks up this easy money
because this is essentially a structural problem with people who have tied
themselves too closely to the land and governments that can't solve their
problems.
~~~
Fjolsvith
Its only a problem for the low income to welfare range of folk. People who
have a better income usually have transportation and use it to shop in bigger
cities where the savings pays for the trip. Also, the trip doubles as a social
outing, where the folk eat out, go to a movie, etc.

Buying a domain may be overkill for most projects. Simply using a subdomain
somewhere (such as a projectname.github.io or projectname.readthedocs.com) is
likely sufficient.
By far the greatest determinant of success for a project are productive and
engaged developer and user communities, and open lines of communication
between these groups (where they are different).
_Which_ communications channels are most important for _your_ project(s) is
something that can't be reduced to simple advice, and will change over time in
any case. Try one at a time, invest more into the ones that have the most
engagement, and smooth the speed-bumps wherever you can.

MongoDB removed from RHEL 8 beta due to license - vbezhenar

It seems[0] the new MongoDB license is basically non-free and it would make no
sense to include it in RHEL8. I hope Debian and other distros follow suit as a
result if they come in agreement. It's sad that the license change all resorts
to greed basically, as if Oracle took over MongoDB.
If I were to ever use a NoSQL database for a new project I'd aim for MIT /
2-clause BSD based projects instead. PostgreSQL has no issue being BSD-like
licensed (all this time I thought it was BSD or MIT, turns out it's a similar
license instead). It saddens me RethinkDB couldn't compete more with MongoDB.

Michael from MongoDB here... Greed? You realize that anyone can still view,
download, use, develop, modify and do everything they could do prior to the
change - right? The only difference is that if they decide to offer the
licensed software as a public service they must release the other components
of the service under the same license.
~~~
jayofdoom
Honestly, from my perspective the problem is more the timing. If MongoDB had
always been licensed this way, companies could make informed decisions about
what product to use. Instead, you pulled a license bait and switch --
attracted people with a free-as-in-freedom license, then switched it for one
that was less free after adoption picked up. That's not behavior I'd
personally support as someone who has a career because of free software, and I
wouldn't support it professionally because of the immense risk a company takes
on when adopting a piece of software for long-term use -- like a DB.
~~~
karmakaze
As you may know there are different senses of 'free' at work here. How you're
using it is as 'freedom to use'. The other is 'freedom of the source code
information' which is to say that derivative works must also be released into
the open. Open-source now has these two competing views. I would complain if
software that was MIT licensed switched to a GPL one as it's switching camps.
I would complain less if a GPL one switched to AGPL. I agree that it's best to
choose the license that matches your beliefs from the start. We must also
accept that a change in license is a distinct possibility and that we are free
to fork.

Of course you can choose a non-free license for your code, but it comes with

Yes, but as a customer of RH, you are not allowed to distribute RH's binaries,
or they will terminate your contract. That is also against the spirit of the
GPL, although not necessarily the letter. You can take the source, remove the
branding, recompile, and redistribute, which is similar to what CentOS
does/used to. However, the GPL allows the former too. i.e., You can straight
up distribute the binaries under GPL.

timdierks
This is simply not true: it's explicitly not the intent of the GPL, and
furthermore the GPL is clearly a contract which explicitly spells out its
intent, not a vague document whose spirit needs to be interpreted.
~~~
bubblethink
It is explicit in the freedoms it grants you, one of which being the freedom
to distribute copies. The intent is pretty clear. The RH workaround to that is
that if you exercise this freedom, they will not do business with you in the
future. You got to exercise your freedom, but only once. The GPL doesn't have
recourse for that.
~~~
Frondo
You _can_ redistribute the source, and that's what really matters. No one ever
made any claims to redistributing binaries, and that's neither the letter nor
the spirit of th GPL.
The GPL is about user freedom, which relies on source code. The whole thing
came about because Richard only had access to binaries for that printer.
And it makes sense that RedHat wouldn't want you to distribute their
binaries...who's to say you didn't backdoor them? That's their name on the
line, too.

"Freedom to distribute (freedoms 2 and 3) means you are free to redistribute

The installation instructions I've always followed for MongoDB start with
importing a key, and adding their official repo to my source list. I'm a
debian user, but their redhat installation instructions are similar:
[https://docs.mongodb.com/manual/tutorial/install-mongodb-
on-...](https://docs.mongodb.com/manual/tutorial/install-mongodb-on-red-hat/)
I guess it will be a small speed bump for people experimenting their first
time, but I've never had any concerns about using a vendor provided source for
packages (third party provided ones are a different story.)
~~~
pilif
_> The installation instructions I've always followed for MongoDB start with
importing a key, and adding their official repo to my source list._
Going with the maintainer's repo means that you trust the maintainer with
providing security updates for the version you have installed or you trust
them with providing a useable upgrade path.
If you go with a distro package, you will get both the benefits of security
updates for the lifetime of the OS itself and the benefits of the underlying
software not changing.
Of course it also means that you don't get new features for the lifetime of
the OS.
So depending on your target usage of MongoDB, you either would want to go with
the OS packages (if MongoDB is just a dependency of a dependency and you don't
really care about its functionality aside of it being there) or with the
vendor packages (if you're directly depending on MongoDB and you're willing to
keep up to date with feature releases).
But even then, sometimes a vendor's official response to a security problem is
"run apt-get upgrade to update to the latest major release" at a time when you
really don't have the time to read the release notes and adopt your software
to the changes in the new version.
Other vendors still provide maintenance for older releases, so it really
depends on the vendor, whereas if you go with the OS packages, none of this
matters.
Also, in this particular case, there's also the licensing issue to consider. I
don't know whether it's safe for a company offering some service and/or
application over the web to use current versions of MongoDB without paying for
a license.
~~~
iqy
>Going with the maintainer's repo means that you trust the maintainer with
providing security updates for the version you have installed or you trust
them with providing a useable upgrade path.
Why should that be a problem if you use the official repo, handled by MongoDB
themselves?
~~~
pilif
Because as I said later in my post, sometimes a vendor's response to a
security issue is "please update to the latest major release".
Let's say you're using version 1.1 of some software and you're hit by a
remotely exploitable unauthenticated RCE.
You want to patch it, but the vendor says that the only fix is to update to
2.0.
How quickly can you adjust your software to work with that major release that
might contain non-backwards compatible changes? Are you going to be quicker
than the time it takes malware authors to write bots to hit that RCE?
There's also a second example which is automated updates: Our infrastructure
automatically applies OS package updates via `apt-get`.
Thanks to Debian only ever updating packages for security reasons and only
very rarely shipping new bugs, this is an actually workable practice.
But once you start adding 3rd party vendors who, for example, believe that
once puppet 4 is released it's totally safe to just publish puppet 4 as a
replacement of puppet 3 previously in the 3rd party repo, this becomes a very
dangerous practice.
~~~
chrisseaton
How does this work? How are RedHat able to reach into any of the thousands of
projects in their repository and fix bugs and vulnerabilities? How do they
have people on staff who understand all those codebases and algorithms?
Do RedHat support engineers get tickets like 'bug in the energy minimisation
algorithm of GraphViz - go in, learn that field of computer science, and fix
it'?
~~~
quantummkv
It is the upstream vendor that issues fixes. What RedHat does is that it takes
the commits that fix the bug and merge them into their forks and release.
~~~
chrisseaton
> It is the upstream vendor that issues fixes.
So if you have a bug in a RedHat package, and you're paying $100k a year
RedHat support contract, all they really do is open a GH issue with the
upstream to ask them to fix it? And then you just wait hoping they fix it so
RedHat can cherry pick it?

myWindoonn
We don't know. I'm going to tell you a short story, though.
Rumor has it that KMS[1] was developed entirely because a deep-pocketed RH
customer was annoyed that their workstations showed a fraction of a second of
the boot/init log, and wanted a more seamlessly-graphical boot.
This feature was not universally welcomed by the kernel community. It excluded
BSD cousins and frustrated nVidia and AMD/ATI. I remember standing next to the
DRM/KMS maintainer while Linus yelled at us.
RH absolutely will interact with upstream on behalf of their customers. They
don't just "open a GH issue"; they present designs, code, rationale, and
evidence to upstream. I wonder whether this is something that Oracle does, but
it doesn't sound like it.

I am really torn about this news. On one hand MongoDB's change of license is a
clear attempt to discriminate against a set of users, so it is clearly non-
free. On the other hand I know it is really difficult to make a sustainable
business by developing an opensource product, especially since there are
companies (like Amazon) who will take successful opensource projects and offer
them as a service, or simply offer a compatible service (which is what Amazon
did now). Discriminating against such uses doesn't seem wrong to me since they
clearly harm the creators and maintainers in their effort to actually make
some income from the project.
There is a really limited set of options for opensource companies and I have
yet to see an opensource product that would bring their creators enough money
to sustain it on aything else than their goodwill. RedHat doesn't count,
because they packaged other people's opensource and sold the package to
enterprise. They did contribute back and even started and maintained some of
the projects (which makes them "good guys" in my eyes), but any other
opensource project will have difficulties replicating that success.
EDIT: I would really appreciate discussion instead of (down)votes.

PostgreSQL is used much more widely than MongoDB, and has a much freer
license. Lots of people make money developing and supporting PostgreSQL.
I also content that MongoDB built their project on top of a mountain of Free
Software. It rings a little hollow to me when they complain that others are
making money from using their software, when the MongoDB team is also making
money from using others' software. Last I checked, they weren't a major
contributor to the Linux kernel, or GNU, or GCC, or Emacs/Vim, or...

MongoDB only needs the Linux kernel/GNU/GCC when it's running or compiling on
Linux. On OSX and Windows it uses other toolchains.
And your point goes against the entire spirit of open source. No one should be
forced to contribute back to open source less they be criticised by the
community.

That right there is what we call irony. This is precisely what Mongo is trying
to do.
~~~
bb611
That's not really what they're trying to do.
What they're trying to do is make it so challenging to host MongoDB as a
service that cloud providers can't do it. They implemented it with an absurd
requirement forcing contributions to open source, but the intent is not to
improve open source, it's to end regain market control.

Somewhat orthogonal but I wonder if this is one of those times where people in

change. I don't completely understand why people getting upset about the
licensing, however.
As far as I know, MongoDB is still open source. If you are a hosting provider
offering "MongoDB as a Service" the provider then needs to pay a licensing fee
to Mongo. This seems ok to me, with the logic that MongoDB is a business that
needs to make money.
I am not an expert in licensing, but how is this any different than paying for
a license of RHEL vs using CentOS? I'm genuinely curious as to how this is
against open source beliefs.

It is not generally considered Open Source.
The new license was rejected by the OSI, which is generally regarded as the
defacto arbitrator of if something is OSS or not. It was also rejected by Red
Hat and Debian as being not open source.
There are various issues with the license, including the scope of what they
considered tainted. You could read the mailing list archives on the subject,
or there appears to be a summary at
[https://opensource.stackexchange.com/a/7523](https://opensource.stackexchange.com/a/7523)
The newly submitted v2 of the license hasn't resolved (m)any of the problems
that the OSI has raised, and isn't expected to be approved either.
~~~
kemitchell
OSI has not rejected SSPL, v1 or v2. Mongo substituted for v2 in review, and
v2 is still in debate.
To my knowledge, OSI has never affirmatively rejected a license. A proposal to
change its process to include rejection, which came up during SSPL review,
remains pending.

MongoDB is a strange company. I've downloaded their Compass software to
visualise some throwaway JSON I had loaded in Mongo, gave my real email and
here's the emails I was sent before I blocked their marketing account
(allegedly someone named Alena)
day 0 "Regarding your interest in MongoDB"
day +1 "Alena with MongoDB in reply to your interest"
day +3 "Alena with MongoDB making sure you're all set"
day +7 "Alena from MongoDB reaching out"
day +10 "Checking in from MongoDB"
At which point I was completely speechless about this dumb spammy marketing
attempt and just blocked the sender. Really guys?
"I want to touch base with you again to see if we could provide you with
additional information regarding our enterprise edition of MongoDB that you
downloaded.
Are you available to set up a call to learn more?"
What the hell is that I never downloaded "enterprise MongoDB", it was Compass.
I will never use anything from MongoDB, thanks Alena.

...why would almost anyone using MongoDB _care at all_ if it's included in a
distro's set of default packages?!
Don't we all _always_ install software from repositories hosted by third
parties? As long as the Mongo devs keep supporting RHEL, I'd see no problem
for actual _direct users_ of it. And SSPL sounds like a pretty good and
sensible thing.
~~~
nolok
It may or may not matter for Ubuntu or Debian or most other distros, but the
kind of users/companies/customers that insist on using RHEL very much care
about it.
The whole point of using RHEL is that it has full support, why pay the premium
for it if you then include non supported gears into it anyway.

MongoDB, Redis, CockroachDB and anyone else interested should join efforts
with Kyle and adopt his similar to SSPL, but neutral and cleaner copyleft
Shared Component License [1]. This should help clear up any confusion people
have and avoid providing excuses for removing packages due to the license.

That's not a free software license though.

kemitchell
I'm not sure what reason you have in mind.
FSF and OSI are split on "private changes": whether a copyleft license can
_require_ distribution of changes. OSI approved Plan 9, RPL, and Open Watcom,
all of which require this in at least some scenarios. FSF rejects those
license.
I don't understand why FSF takes that position. More on that:

Good, Mongo is rarely the right database.
~~~
TimMurnaghan
Absolutely. My characterization of Mongo is that it's the back end choice of
front end developers. The only possible justification for it could be time to
MVP (and that's being kind). It's bad for all of the reasons that back-end
people make back-end choices - non-functional requirements like operability,
clustering, etc.
Hopefully this is the start of it being removed from any infrastructure uses.
I spun up an openstack instance the other day and was horrified to find Mongo
in there.
~~~
threeseed
Actually the NFRs are one of the best parts of MongoDB.
It is by far one of the easiest databases to administer, clustering is orders
of magnitude easer than say PostgreSQL and it can be the fastest database by
far for certain use cases e.g. cell level updates. Can you be more specific
about what in particular is deficient ?
And if you look at their customers most of them aren't using it for front end
work. Likewise I find it to be quite popular in the Data Analytics/Science
space as a store of analytical features and for 360 entity views.
~~~
tracker1
Agreed to an extent. It does have its' place and is definitely very easy to
use if you have a limited number of collections, mostly distinct in use and
have deeply structured objects.
The ease of clustering is pretty nice for either replica sets or basic
sharding, but sharding + redundancy isn't great, and if you happen to have a
majority of nodes offline it may never catch/sync up right again which may
require bringing on/off new nodes or the whole thing down and restoring from
backup.
About 4-5 years ago when a bulk of Azure went down, I experienced this, and it
wasn't fun to say the least. Fortunately it was mainly a replica of primary
data source for search/display for mostly-read scenarios and was easier to re-
replicate the records from SQL in the end. If I were to do it again, I'd
probably reach for Elastic first.
It can be very good for some use cases and less than good for others. The
clustering is absolutely easier than anything but RethinkDB (in the box) and
SQL Server (break out your checkbook) in my opinion.

That Perens quote refers specifically to Sunil Deshpande's article about the
SSPL and Open Source, not to the SSPL itself. But it's not far off either way…
The reaction on the OSI's license-review list is more varied. Lawrence Rosen
and Ken Mitchell argue that the license should be approved. Everyone else is
criticizing that it clearly violates the spirit of Open Source software (no
discrimination against fields of endeavour!), and that the license is too
broad and too vague in the critical section (Rosen agrees with the latter
part). Carlo Piana points out that the goal of the license seems to be to
create so much legal uncertainty that any serious user would be forced to buy
a proprietary license from MongoDB.
~~~

I also criticize the way SSPL was drafted. The legal talent they have can do
far better. The choice to patch AGPL cuffed them.

The Problem With Posterous - OoTheNigerian
http://oonwoye.com/2011/01/31/the-problem-with-posterous/
======
joelg87
I think you make a great point here.
The thing I find interesting is that looking back it feels to me as though
they did indeed get their first traction by carving a niche and being the best
at _one thing_.
In my mind, Posterous _were_ the best at blogging via email. In my mind, they
were the blogging platform for people new to blogging. I personally introduced
a few people to Posterous simply as a way to blog without using anything they
didn't already know. It was simple: the headline is the email subject, and the
body is the content of the post. They chose to steer away from that being a
USP, I am assuming for good reasons.
You're right about it being hard to focus, however perhaps there is a strategy
amongst it all. If they try and do a number of things maybe they can find one
thing which people like the way they do or which Posterous find they are
particularly suited to delivering a potential "best at" solution for. Then
they could focus. It is almost like instead of systematically pivoting from
idea to idea, they are doing all the pivots at once. This could, of course, be
a complete misreading of their strategy.
------
LeonW
Oo, I agree 100% with your view. The exact same thing happened to me when
using posterous. It's really cool to start with, but I feel I am not really in

blogging platform available for your metnioned reasons. The wealth of plugins
is simply awesome. Only recently I started using Tumblr and you are right, the
design is outstanding. Community seems to be far easier to build as well. I
can only say, I won't go back to posterous if there is not a big change in
what they are doing. Oh and nice last sentence ;).

To me this is heartening in a variety of ways.
One is that we're finally making good on the promise of the Internet. The hype
was that it made location irrelevant. And it did for a lot of things. But
somehow VC-backed web and companies were immune to that, even though money and
software are both digital.
Two is that this is great news for founders everywhere. Before they often had
to choose between family and success. Now they can have both. (That didn't
matter to me much when I was 25, but now it's easier to see costs of that.)
Three, I think this is great for customers and users. A frequent and
frequently valid critique of Silicon Valley startups is that many only make
sense in our hothouse atmosphere. E.g., Juicero. There are real-world needs
out there that we're missing because we don't see and spend time with the
people who have those needs.
Four, I believe that this is good news for both our cities and our startup
community. The flood of money has driven up prices just like it did during the
gold rush era. That's certainly a problem for people outside of tech. But I
think it's also bad for entrepreneurs: it keeps getting more expensive to
build a team and a company here. Turning down the heat a little will make it
easier for us all to succeed without having to take gobs of money.

_[R]emote exchanges of ideas are no substitute for the elemental human process
of face-to-face communication. Innovators don’t do their work in isolation;
they stimulate one another._
Historically, many have. And today, when you can ping almost anyone in the
world, it's not an obstacle. Not to mention, most big cities have a research
university (if not multiple). Nobody is lacking for input. The claim about
"elemental" processes isn't based on anything concrete. I work in multiple
remote teams and it's never been an issue. We get more work done than if we
had to see each other every day.
That's hardly an endorsement for SV alone unless SV has all the talent in the
world (it doesn't). I think your post and some of the other posts advocating
for SV have knowingly or not accepted a belief about how things work, but they
are essentially mythologies.
Some work as loners, some work in groups. The biggest mythology of all is that
it takes hundreds of millions in funding and unethical behavior to build cool
stuff - it doesn't. That seems to be the SV way, many of us don't want that.
~~~
bobthepanda
Those historical loner inventors were inventing much simpler things than we
work on today. Every city with a university has a baseline amount of research,
sure, but at some point a critical mass is more useful.
Agreed on capital - all that VC money slushing around is more akin to chasing
the next big thing rather than fixing real world problems. It's just that
tech's reliance on unconventional methods of funding makes SV startups more
prominent than startups in other industries.
~~~
aaron-lebo
Were they? Individuals are more than capable of learning linear algebra, web
frameworks, or any given hot tech in SV. Those historical loners had the
massive disadvantage of not having reams of material detailing it and in some
cases didn't have modern science because they invented it.
There's almost nothing going on in SV that actually requires large teams or
funding, that's just how things are done. Even if individuals have
disadvantages v groups, those disadvantages aren't obvious when the phds and
top of the class people at Google are building incompatible chat apps (what do
they have, 4?) and those at Facebook are forgetting to renew security certs so
that VR headsets don't stop working. There's a massive amount of inefficiency
there, and at times mediocrity, and that's possible when everyone can pass the
buck. It's not nuclear fusion.
Surely the people at those companies as individuals are capable of producing
much more than that?
~~~
wpietri
You seem to be ignoring the gap between "large teams" and individuals. The
sweet spot for a lot of tech innovation is single, modestly-sized teams.
Individuals working alone, though, are very rarely successful. There are just
too many skills for one person to have, and a solo founder loses the advantage
of different perspectives clashing and collaborating.
Unsurprisingly, investors are very reluctant to fund both solo founders and
large teams. Seed money to support innovative work ends up mostly going to
groups of 2-5 people.
~~~
aaron-lebo
I agree with you, but we just weren't discussing it.
My main point is it is possible for individuals to do great things. The gap
between that and 75,000 person companies is not just huge, it's massive.
Honestly, what investors will or won't fund isn't that interesting to me
because it seems to be root of lots of short sightedness. Investors have
concerns antithetical (in many cases) to building great stuff.
My belief is the market's reliance on investors has biased what is or isn't
possible. If so many people weren't concerned about what they would fund, we'd
probably see more solo founders and we'd probably see more success there. With
investor money around, there's less reason to do that, unless you are a
masochist.
But yeah, most projects aren't single person, and groups have advantages even
if they can be.

The headline is clickbaity. The point isn't that Silicon Valley isn't a major
force in tech or that other parts of the US will "beat" it. Rather, it's that
you can build valuable tech companies outside of it, and that the Midwest in
particular is ripe for more tech companies. I know first hand, I'm building my
VC-backed (including coastal $) startup in Madison, and we've stayed put. I
realized the pressures we felt to move early on were our own insecurities and
the bias of tech/investor media (which I've noticed has changed recently,
we're not seen as so crazy!)
I'm glad we stayed put, especially as we've started to focus on real revenue
and scaling, and less on trying to be hot for the purposes of raising a big
early round. I feel like the market for engineers around here is becoming an
advantage for us, and we're not having to fight the same talent wars as those
on the coasts. That matters.

wrong.

easy.

ryandrake
Is there any company out there who actually says “our compensation is NOT

salary” it means the company can’t think of a more positive word to describe
it that is also truthful.

yesimahuman
I'm really not sure what your point is. If you're losing candidates based on
compensation being too low, then you're not competitive.

ryandrake
Everyone at least says their compensation is competitive—-it’s not a way for
an employer to differentiate. As a candidate, when I see the word
“competitive” that tells me it’s lower than “generous,” “excellent,” “top of
market,” basically lower than any other description of compensation out there.

The abundance of startup jobs and VCs in Silicon Valley is not matched
anywhere else, and this makes quitting a stable job and working for a startup
/ starting a company a far less risky proposition than if you lived in an area
where there were maybe 1-2 startups big enough to hire reliably. In those
places people just don't make careers of working in startups because there
aren't enough jobs / funding
That said, there are a lot of complicated industries where domain expertise
trumps tech ability (healthcare is a prime example). Most successful health
tech companies are not in CA (epic in Madison and cerner in Kansas City as two
big examples). As more people learn to code I think there will be a growth in
startups with relatively simple tech that is just well suited for the problem
it addresses. Solutions that don't scale to millions of users / are not
optimally performant but are designed by users can win in a lot of sectors

There are also things on the coast that you simply can't get in flyover

Good luck going car free anywhere in the Midwest outside of Chicago- and I
mean at all, period. Even if you do, you still don't have the opportunity to
experience the other- say, if you have friends with cars...which sounds pretty
plausible to me(SF or otherwise)...if you think public transportation in the
Bay Area is bad...every single city in the Midwest(outside of Chicago) is
shockingly bad. You can commute 5-20 miles round trip by bicycle if you want
if you feel like having your life threatened by motorists on an almost weekly
basis(I speak from experience).

FWIW, my confrontations on public transportation haven't been any worse than
confrontations on the road (rare occurrences; current 60-mile commute, 24
years driving).
A car is very much a rite-of-passage here still, sure. For those that can
afford it (that is the bad part about it), it's the most freeing, invigorating
thing you can own at 16.
Being car-free seems completely asinine here; you're going to need it for
something. That's the lifestyle here. No worse than a bicycle. And one day,
when we can go emission-free; it really won't be.

Silicon Valley has a radically different viewpoint and set of priorities than
the rest of the world. This discrepancy still has not been exploited to
anywhere near its full potential.
Edit: To clarify, I think SV is increasingly insular, and there is untapped
innovative potential outside the bubble.
~~~
IAmEveryone
The singular success of SV might point to some of its values being linked to
its success. “Correlation is not causation” doesn’t even apply, because
regardless of causality (a->b, b->a, or even x->a && b) it would seem that
it’s difficult to have one without the other.
It’s also important to note that the high reaches of other creative industries
espouse values very similar to those of The Valley.
~~~
jerf
Times change. The "SV values" of 40 years ago are noticeably different than
the ones of today. Heck there's been a pretty noticeable shift even in the
past 5 years. If SV did have the right values for success 20 years ago, I'd at
least put out the suggestion that that opens the possibility that it doesn't
have the success values today.

This is one of the many things that keeps SV dominant. Unless this changes in
the MidWest, things will stay the same. It will still be more beneficial for
your company to move to California than stay if you need money. Investors in
other parts of the country (and the world) are just less risk tolerant than

Apologies for the tangent - I have never been to the bay area, but I am
frequently reminded many times when I meet a “pure tech company” ala google,
msft, amzn, fb software engineer (I’m only 3 years out of school, studied CS)
of this self-righteous and condescending narcissism that I haven’t seen
repeated across other workers in other industries and a kind of deep sense of
self-congratulatory entitlement. It is a little bit akin to what you see with
Ivy League students -> Banks/Mgmt Consulting, but infinitely more detestable
given how flippant toward the rest of the world the tech attitudes can be.
Silicon valley is obviously the new wall street in terms of attracting the big
brains and bringing a focused collection of hard working or brilliant
individuals - yeah, we need the infrastructure to make the world spin faster
but it can really bring out the worst and most myopic visions even from the
“best and brightest”. I like automation and disruption, purely for its own
sake, because we can. But the hyperaccumulation of wealth driven entirely by
advertising is absurd and is effectively non-productive and I hope more people
refuse to take classical VC funding and instead opt for organic growth and/or
pure public raises. The only reason a web app development company (basically
all these startups) that is 6 months old needs 5 million bucks is to create a
legal fiction that from its inception is designed to create liquidation events
that make VCs extremely wealthy, done in a way that gives the impression of
“risk taking” without any real risk being taken because of the ability to
create unicorns from deliberate successive raises - all of these entities
exist within the same monoculture, with huge overlap in board of directors and
investor groups.
I think that ICO related innovations can help in potentially mitigating the
development and solidication of this monoculture as we have seen in Wall
Street, but unfortunately the criminality of some of the newer players in this
field is staggering and equally disappointing
Tech almost certainly doesn’t need Silicon Valley and a decoupling of peoples
thinking in those terms will be very useful step in the right direction

I think this conversation is missing a big piece of what made SV in the first
place. Namely, the military industrial congressional complex. I can't remember
the author but he gave a good Google talk on the origins of SV from war
engineering.
I think since the type of warfare of the future is largely informational, and
governments are increasingly neo-fuedal and authoritarian, in the future SV
will be seen as a base of operations of the enemy of tech. Not only does tech
not need SV, but they are going to largely be at odds. SV will probably still
have the highest concentration of VC to IPO cycles but the problem is so many
of them aren't solving problems with products or services and are generally
focused on how to turn customer data into an advertiser money pit while they
angle for the IPO boom and exit (betraying users more and more the closer the
exit is)
I'll tell you what tech does need though... non SV big money representation on
the hill.
That said, there some good things in SV like the EFF, and I don't have much
knowledge of the area other than riding my Harley up 1 to visit a friend a few
times. I do know Pelosi is a a horrible authoritarian in democratic clothing

Tax incentives means competing on price, which is a loser in the long run.
Lower taxes sounds good until you consider the implications: less money

* Not a lot of congestion just means they have car-dominant sprawl that hasn't hit a huge economic boom yet. That's a downside to me.
* Somehow I really doubt their restaurants are significantly better than the bay area, NYC, or Boston.
* Home prices aren't so much a quality of life advantage as a cost of living advantage.

Or, perhaps the Laffer Curve? Maybe revenue actually increases? Look at Texas:
huge budget surpluses and lower taxes and public schools ranked higher than
California.
I am not trying to debate which state is better, but I am trying to make the
point that lower taxes does not correlate to a lower quality state. A poorer
state does correlate: such as Mississippi for example, but low tax “rich”
states do just fine.
~~~
TulliusCicero
Yes, but look at what usually happens. For example, most of the top 10 GDP per
capita states are blue (and the ones that aren't are tiny petro states), while
most of the bottom 10 GDP per capita states are red. This directly contradicts
the conservative mantra of "low taxes spurs economic growth", if anything it
looks like the opposite is true.
> I am not trying to debate which state is better, but I am trying to make the

Well, "quality" is a pretty subjective word, but it does seem to _generally_
lead to certain things being worse, like social safety nets, education, etc.
For example, in the case of Texas, it also has an insanely high maternal
mortality rate, and while public schools there may outrank California's,
California has an extremely strong public university system.

sure Silicon Valley sucks from a housing stand point, and you’d think that you
can fire up an AWS instance from anywhere, and you can. However SV has one
thing no place else has, a density of talent and capital unrivaled in the
world. That’s why it continues to exist.
Compare it to Hollywood. Sure you can make movies anywhere, but you don’t.

Hollywood's not a great example. Their centrality to the movie industry has
been declining for decades. E.g.: [https://www.thewrap.com/louisiana-

work-as-a-moviemaker-2018-big-cities/)
One important factor at work here is the Internet. Effects companies, for
example, are all over the place, including London, New Zealand, Vancouver, LA,
and even here in San Francisco. Big movies will often use multiple companies,
something that would have been very challenging 30 years ago.
Silicon Valley does have capital and talent. But it's not like that capital is
in doubloons in a vault. It's purely digital. A big reason it's not more
mobile is that VCs wouldn't deign to stop in a flyover state. Talent isn't
quite as mobile, but a) advances in technology mean talent is less necessary,
and b) the rise in remote work means the location of talent is less and less
meaningful.

I grew up in Fishers, and currently go to Purdue (an hour north). I can say
from what I've seen that tech really _is_ coming here, it isn't trying
anymore. I know there is a lot of 'Silicon Valley of X', but I don't think
Indy is trying to be the next Silicon Valley. It feels like the people here
are content at solving problems big and small, and not as focused on capital
and business. Personally I think this a good thing, and prefer it. And of
course as the article states, a little Midwest politeness pervades the area.
Salaries are also way higher in the area then they used to be (expect maybe
$50,000-60,000 in the area, at least for new grads in the area for larger name
companies). It's not SV wages, but it's not city living either, and the area
is great.
To follow some of the people in the area, I'd look at @DonWettrick [0] on
twitter, he's an educator in the area and a lot of his students are a part of

the next generation, definitely a class to keep up with!

In my experience, if you like working and you're top 10%, you will do well in
a big city. By the time you're 26 to 28, and you have an MBA/JD/MD, I see my
friends making $200k+ easy. If you're in this group, then you're household
income is $400k+ easy, but the big difference is the connections you're making
which can enable you to go up to 7 and 8 figures or more. Really depends what
you want to gamble on, but if you're top of the class and want to make money I
would definitely try out a major city.

Leonid Gavrilov and Natalia Gavrilova are a good resource for this sort of
demography and epidemiology of aging. [1] In particular they have a lot of
material on season of birth effects. [2]
Tangentially related to the seasonal effects is data suggesting that solar
cycles also influence longevity, possibly through quite indirect responses to
levels of UV exposure in pregnant women. [3] You can see how this might be
relevant to season as well, but it is only one of a number of mechanistic
theories on the subject.
This sort of thing ties back in to application of reliability theory to aging
[4], wherein to make the models fit the observed data individuals have to be
born with a preexisting non-zero damage load.

The correlation is in terms of fractions of a year so they add up to an
average of plus-or-minus a few month over a lifetime. The three curves don't
seem to have a very close relationship to each other though there are some
similarities.
I assume that if they are getting a meaningful correlation, it is over a large
amount of data. It seems logical that at large scale, date born would
correlate with a variety of things in various areas - social class and wealth
come to mind.
I think it's a matter of taste whether one says "wow, throw enough data
together you find unexpected correlations" or "garbage in, garbage out". A
life insurance company could eek out a bit of profit changing its price
structure on this data - if it didn't have far more to lose if the use of such
tactics became public.

Would be interesting to look at the 'stresses' that occur within schools. My
11 year old daughter was born on the 30th of August. Ergo she is the youngest
in the year at school. She is studying with people that have a year of
development on her. She is doing fantastically well but works hard to achieve
that result.
My hypothesis is that the age cut off in schools, unduly puts stress on the
younger children in a class, that long term, impact on health in later years.
In effect which month you are born in affects the stress you will feel during
your school years as it will be inherently 'harder' for you.
~~~
beaumartinez
I'd think the opposite. Since she is used to having to work hard from a young
age, she will be more successful in life.
Others who coasted through—whom were used to everything being relatively
easier—will not have the experience she has already accrued when faced with a
harder challenge.
~~~
awjr
Not sure that makes sense. She potentially experiences 12 years of increased
stress compared to her peers. I'm not implying that later in life, she will
have better tools for work, but that her body would have spent most of her
formative years under more stress.
This would then reflect in a shorter lifespan.
Note however that this concept she would gain the tools for hard working in

This is very hard to measure as you would be looking at teaching practices in

potentially, nationally, this would be possible as most nations have been

It could also have something to do with their development in school. After all
the school year is the same for all. Some kids are up to 11 months younger!

danielbarla
This is an area which I've personally experienced, having spent the first half
of my school years in Europe, and being a few days shy of the cut-off point
for being held back another year, I was always the youngest in my class (I
guess on a large enough population, it would mean that similar kids are the
smallest as well, on average).
Later on I switched to a southern-hemisphere school, which was out of phase by
6 months, and I was all of a sudden roughly average age in class. Not that it
had a huge impact on me, but it was noticeable, which probably means it has
some effect on average.

jcampbell1
Depends on the rules which vary by location, but you want your kid to be the
oldest in the class. Your older kid is going to believe she is very bright in
1st grade, and have a lifetime of confidence to achieve great things. The real
reason she was such a good student in 1st grade is because she was just older.
~~~
desdiv
I know this sub-thread started in half-jest, but your response got me
thinking:
1\. Month of birth directly determines a child's age compared to their
classmates.
2\. An older child among younger peers performs better academically.
3\. Academic aptitude is correlated with income.
4\. Income is correlated with longevity.
Admittedly, hypothesis #2 is iffy. And the good old "correlation is not
causation" adage applies for #3 and #4.

saraid216
> And the good old "correlation is not causation" adage applies for #3 and #4.
It does, but it's not hard to come up with plausible causes for the
correlation to support in those cases.
It is probably more accurate to say "Academic aptitutde correlates with job
stability which correlates with lower overall stress levels which is part of
the definition for better health which correlates with longevity."

I didn't fully read it but doesn't it look like there is potentially a big

They touch the subject with their 3rd hypothesis but in general it's possible
that you still have a higher life expectancy being born from April-June in the
Northern Hemisphere because you have increased chances of reaching 50.
So why this limit of 50 years? What is the expected lifespan for newborns
depending on their month of birth?

Except that any historian of medicine will tell you that pharmaceuticals well
into the 18th century were dominated by ideas of "potency" where surely things
would have beneficial effect because they have powerful smells or whatever.
Uses of animal excrement are exceedingly common in early-modern remedy guides.
~~~
yobuko
I remember learning from a historian that the use of animal excrement was used
for all kinds of things; for example "curing" warts. The effectiveness was of
course questionable, but that didn't stop people buying in to the hype of the
day.
Someone else recently posted about the Templar diet[1], and I thought that was
actually quite ahead of it's time. What I find most interesting is how they
could have been so ahead of the times in terms of diet and hygiene compared to
the "average Joe".

In defense of at least that wart remedy, a wart will turn green/black pretty
much right away and then fall off relatively quickly if you keep it saturated
with vinegar for a few hours here and there. I am willing to believe that some

London, and other towns and cities, had a bit of a shit problem in the 1300s.
Streets full of horse and human shit, households throwing their waste into the
streets and/or river or if lucky selling it to a nearby cloth dyer, water
dangerous to drink so best stick to beer or wine, the serious health risk from
floors covered in rushes. OK, if you were posh enough there was a chute from
the privvy straight into the moat or river. Oh and the river was where the
leftovers from the slaughter houses went.
I think it's fair to say that smell and hygiene expectation was a little
different in the middle ages. Cured, if wealthy enough, with a pomander - a

This was a good explanation of what's happening here from a previous thread:
[https://news.ycombinator.com/item?id=13715761](https://news.ycombinator.com/item?id=13715761)
The key is that essentially all of the data for both images are in both PDFs,
so the PDFs are almost identical except for a ~128 byte block that "selects"
the image and provides the necessary bytes to cause a collision.
Here's an diff of the 2 PDFs from when I tried it earlier:

Not to say that there isn't still something exploitable here, but I don't

edit: Here's a diff of shattered-1.pdf released by Google vs. one of the PDFs
from this tool. The first ~550 bytes are identical.

niftich
I didn't get a chance to make this point in that other thread, because the
thread [1] of its follow-ups quickly morphed from promising [2] to meandering,
but the combination of lax formats (PDF and JPEG in this instance) makes this
style of collision particularly reductive, and in a sense, a cheapshot, if
still devastatingly damaging given both PDF's and JPEG's ubiquity -- both
separately and together -- in document storage and archival.
This shows the importance of techniques like canonicalization and determinism,
which ensure that given a particular knowledge set, that result could only
have been arrived at given exactly one input. For general-purpose programming
languages like PostScript, of which PDF is a subset, this is essentially an
unfulfillable requirement, as any number of input "source code" can produce
observationally "same" results. Constrained formats, and formats where the set
of 'essential information' can be canonicalized into a particular
representation should be the norm, rather than the exotic exception,
especially in situations where minute inessential differences can be cascaded
to drastically alter the result.

That might be very challenging in practice, because a more expressive language
directly allows a more compressed/efficient encoding of the same information,
but at the cost of being more difficult (or impossible) to create a canonical
representation.
Also, data formats that are purposefully redundant for error tolerance all
basically have the property that readers should be tolerant of non-canonical
forms. If we want to redundantly represent some bytes redundantly in case of
data loss, then there _must_ be multiple representations of those bytes that
are all acceptable for the reader for this to work.
Video and image formats use multiple encodings to give encoders the room to
make time-space trade-offs.
~~~
acqq
I agree, for anything that a human is supposed to see with the eyes, there are
always different representations that look the "same" enough to be
indistinguishable.
People should be aware of it, not believe in a non-existing world where it
isn't so.

Shameless plug: I built my own version of this to collide arbitrary PDFs:

~~~
versteegen
Excellent! This ought to be the top comment; have you submitted it separately?
I was considering implemented the same thing, since there wasn't any reason
for those limitations. The Google researchers purposely designed this
collision to be highly reusable, probably to encourage everyone to generate
lots of fun examples which will be spread widely and break systems everywhere
:)
I'm surprised that some PDF renderers have problems with JPEG streams that
contain comments and restarts. Actually, glancing at the JPEG spec, I didn't
even realise that restarts would be needed, I thought this was just done with
comments. Is this really "bending" the spec, or is GhostScript buggy, or is
the problem that it's assuming that restarts don't occur inside comments
without escaping?
~~~
nneonneo
I did submit it, but I don't think anyone saw it:
[https://news.ycombinator.com/item?id=13729920](https://news.ycombinator.com/item?id=13729920).
I was trying to finish it in time to catch daytime folks but work got in the
way :)
Comments are limited to 65536 bytes, and the JPEG spec doesn't offer any way
to break an image stream up except for progressive mode or restart intervals
(otherwise, the image stream must be a single intact entity). The trouble is
that it's probably not _technically_ legal to stick comments before restart
interval markers (putting comments _after_ the markers just breaks all the
readers since presumably they are expecting image data). So, GhostScript's
JPEG reader gets confused when it fails to see a restart marker immediately
following an image data chunk, and aborts decoding.

TorKlingberg
Wow, it works! I thought this was supposed to require Google-level resources

similar ones?

kiallmacinnes
yea, this.. wow.
Is this the first hash function which went from "secure" to collision-as-a-

research particularly strong? or maybe something else?
~~~
schoen
As other people explained, and just to summarize, this service is a way of
reusing Google's specific collision (as a prefix to new collisions), and isn't
a way of making arbitrary colliding files or file formats. You can't, for
example, use this to make something other than PDFs that collide; for that,
you'll have to redo a computation on the scale of Google's!
~~~
orblivion
I thought I heard that some file formats have "headers" that go at the end of
the file. I think a demo of this was a file that was both a zip and a PNG or
something. If I remembered right, you should be able to make a similar hack
here.
~~~
schoen
If the _only_ headers are at the end, then yes, that's a really neat idea. I'm
not sure of the constraints for zip files. Maybe it would be interesting to
brainstorm with some people with a lot of file format knowledge to find
additional such formats. But if the formats have any constraints at all on the
first few hundred bytes, those generally won't be satisfied by the prefix
here.

According to [the Shattered

the reason why the proof-of-concepts are PDFs is because we are looking at a

> suffix S
They have already precomputed the prefix (the PDF header) and the blocks
(which I'm guessing is the part that tells the PDF reader to show one image or
the other), and all you have to do is to populate the rest of the suffix with
identical data (both images)
~~~
danielweber
Yep. With any hash function that takes input as blocks, if you were to ever
get two messages to generate the same _EDIT_ internal state, you could add the

Is this length extending [1] the already existing Google attack?
[1]
[https://en.wikipedia.org/wiki/Length_extension_attack](https://en.wikipedia.org/wiki/Length_extension_attack)
Edit: yes, looks like it is.
As sp332 and JoachimSchipper mentioned, the novelty here is that it contains
specially crafted code in order to conditionally display either picture based
on previous data (the diff). I can't grok PDF so I still can't find the
condition though. Can PDFs reference byte offsets? This is really clever.
Edit #2: I misunderstood the original Google attack. This is just an extension
of it.
~~~
TorKlingberg
It seems so. I can add the same arbitrary data at the end of two pdfs
generated by this tool, and they are still a collision. I didn't know SHA-1 is
so susceptible to length extension. Is there no internal state in the
algorithm that would be different even if the hash output is identical?
~~~
danielweber
If you were to somehow get two messages with the same SHA-3 hash, you could
keep on appending the same data to both and they would keep the same SHA-3.
But SHA-3 is explicitly not vulnerable to length extension attacks.
~~~
fivesigma
No they wouldn't, since its internal state is different than the output.
Same goes for SHA-224 and SHA-384.

Damn, right, you have to get them with the same _internal state_.

lokedhs
I have never been particularly comfortable with the idea that you can simply
assume that if the hashes are the same, then the data must be the same.
The fact that collisions happen so rarely (and sometimes only after the a hash
function has become compromised) makes this even more dangerous.
It's like a couple of decades of strong hash functions has made people forget
what hashing actually is.
------
neo2006
I don't understand the whole collision thing. I mean a sha1 is 160bits so if
you are hashing information longer then that collision is a fact, being able
to forge a piece of information with constraints is the challenge and even
that with enough power you end up being able to try all the combinations. What
I understand from that collision reported is that they use PDF format which
can have as many data inserted to it as comment /junk as you want so all you
need is enough processing power to find the right padding/junk to insert to
get the collision. Am I missing something here ?
------
grandalf
I would imagine that a lot of old data is secured by SHA1, which may be
available for attack.
Does anyone have any idea about a broad risk-assessment of systems worldwide
that might be vulnerable as SHA1 becomes easier and easier to beat?
~~~
danielweber
If by "secured by SHA1" you mean "someone generated a hash using SHA-1 and we
use the validity of that hash to guarantee we have the right document," that's
still okay. We're a long way from being able to make documents with a given
SHA-1.
(Edit: Any _newly_ signed documents, or documents signed recently, are not
safe, because an nasty person could have made two, one to get signed by the
system, another to do evil with.)
SHA-1 is officially deprecated for certificates, because of the example that
OP shows. You can create two certificates, have the decent one get signed by a
CA, and then use the evil one to intercept traffic.
~~~
grandalf
Thanks for the info. Good point, I suppose anyone relying on SHA1 in 2017 has
had ample warning about its weaknesses.
It seems that there is also a very strong incentive for anyone receiving
anything whose authenticity is verified by SHA1 to request an improved hashing
algorithm.

This overstates the difficulty of creating a JPEG. If you have an image editor

could certainly be a hassle.

I have always been a big fan of rap vocabulary, and I've already lost an hour
poring over different results. What would be amazing would be a cross-
reference to the Google Trends results for the same words. You could try to
see the difference between cultural events (global) and specific events in the
rap community (local) that caused certain words to spike or ebb.

Regarding the NBA chart: "Jordan, Kobe and Lebron":
> Rap and professional sports have always gone hand in hand, and we can see
> the evolution of rappers’ favorite basketball players:
"Jordan" keyword for example would more often be used in reference for Nike
shoes, so not a direct representation of the sports players popularity.

How did the Teddy bear get its name? The popularity of plush bears doesn't
much reflect the popularity of Theodore Roosevelt.

Not really the same thing. Those bears weren't named after Roosevelt and thus
don't reflect his popularity whereas Jordans were clearly named after MJ
himself.

I never liked rap and I can finally explain my reason:

And I've heard a lot of rap. My highschool bus driver always played rap on the
bus's radio every time we had him as a driver. Honestly, I went to school
angry every morning. Similar to how you feel when you try to listen to Glen
Beck or Rush Limbaugh.

eulerphi
Hahaha, what an awful reason. Keep white knighting and see how your life turns
out.

PhasmaFelis
"White knighting"? Fuck off, troll.
~~~
eulerphi
Not trolling, you're assuming that all those words are used in a derogatory
manner and discarding the actual content of the music so you can "defend"
women. You're a pathetic white knight.
~~~
PhasmaFelis
Bahaha. I don't care about rap one way or the other, and neither do you.
"White knighting" is just as made up as "fake geek girls" and the Tooth Fairy,
and we both know it. Therefore: fuck off, troll.
~~~
eulerphi
I do care about hip hop. White knighting is as made up a word, as any words
are. You have the mentality that if you bend over to defend women, it will
somehow make you more righteous of an individual. Women don't need defending.
And those terms can refer to men as well.
Let's just put this in perspective Robert. You're a KFC nerd who plays video
games, knows a little programming from modding them, you don't shave your
neck, hang out with your cat, and defend women's social justice with respect
to rap, through some poor analysis of word frequency on supposedly derogatory
"demeaning" words on women. Somehow, hoping this ill-formed sickness of a
view, helps women recognize your sentimental romance toward their engendered
cause. Ain't gonna happen Jack. Be a man and stop playing internet politics.
And lay off the Hollandaise sauce.
~~~
PhasmaFelis
Interesting! But far from accurate, I'm afraid. For example, my neck is as
smooth as a baby's ass.

we have a higher quality of discourse than that.

Haha. I agree that rap diverse, and I was just having some fun comparing the
genre to programming.
Setting aside jokes, I've listened to many different types of rap, but I don't
like rap that's intellectual. I prefer the mainstream songs about drugs and
partying (e.g. Rick Ross and Lil' Wayne) to the songs that try to start a
dialogue about social issues (e.g. Common).
I'm open to hearing about intellectual issues when I read articles or listen
to talk radio, but I really don't like music that tries to make a point
because I associate music with entertainment. Interesting how the medium can
affect the message on a person to person basis.

Doesn't have to be an issue about social issues to not be plain retarded in

flycaliguy
I think for this argument to be sound we have to define what artists would be
included. Is it a survey of popular music? All music? There is a lot of
intelligent hip hop out there. There is a lot of shallow rock out there.
Generalizing about any genre is pointless.
Edit: And I put intelligent in quotes because who is to say that using the
word money or (less so) bitch even means there is not an intelligent point
being made.
~~~
beloch
I admit I was trolling, but the amount of rap out there that plays into the
macho-gangster-materialist-misogynist stereotype is _obscene_. Decent rap does
exist, but gangstacrap still dominates the genre. Other genres of music have
their own dominant stereotypes that are equally vapid, but seldom as scummy.
~~~
dasil003
You're conflating stupidity with poor taste, but they're clearly independent.
Consider the Wu-Tang Clan's lyrics which are more intelligent and have a level
of wordplay that is non-existent in rock music, but at the same time can be
the most offensive thing you've ever heard.

Did China steal Japan's high-speed train? - w1ntermute

======
DigitalSea
The quote by Li Daokui in the article: "Don't worry too much about Chinese
companies imitating you, they are creating value for you down the road" is
probably the best way of putting this. The world needs to invest into bullet
train technology, the world is expanding and becoming more connected and yet
trains have remained basically the same for the last 100 or so years. You take
the risk of having your IP stolen by any country (China just so happen to be
quite good at it). If any one country can take a new technology or method of
doing something and ramp it up to benefit everyone, China is probably the
country best suited to the task.

Ask HN: Why can't we stop hurricanes? - aashaykumar92
I googled this and see theories as to how to stop hurricanes -- decrease water temperature under eye of storm, send supersonic jets in to revolve and cause hot air to rise, lasers, etc. -- anyone have a simple reason why these haven't been tried or are absolutely crazy?<p>A follow up: so how can we stop hurricanes?
======
SAI_Peregrinus
[https://en.wikipedia.org/wiki/Orders_of_magnitude_(energy)](https://en.wikipedia.org/wiki/Orders_of_magnitude_\(energy\))
The energy needed to evaporate the water Harvey dumped on land (33 trillion
gallons) is roughly: 40.65 kJ/mol (Latent heat of vaporization of water) * 210
mol/gal * 33x10^12 gal = 2.8x10^20 J. That's over half the entire world's
energy consumption (not just electricity, also fuel for transportation and
such) as of 2010. In about a week. And ignoring the energy in the wind.
They're simply really, really, big. Causing substantial change to them once
they've formed is effectively impossible. Stopping the formation is
effectively impossible because weather is chaotic, so small changes in one
place can cause large changes elsewhere. You might stop one hurricane forming
only to create a different one.
The real solution is to kill all the damn butterflies. /s

This [1] is the NHC report for Hurricane Andrew just prior to landfall in
August of 1992. Andrew was small as hurricanes go, and even then, you are
talking about hurricane winds (72 MPH/116 KPH at the _low_ end, Andrew was 140
MPH/225 KPH sustained winds) extending outward from the eye (typical eye
diameter is 20 miles/32 km) 30 miles/45 km. So you are talking about
disrupting a cylinder of wind and rain some 50 miles/80 km across and what? 4
miles/6 km high? That's a _lot_ of energy to disrupt. And that's for Andrew, a
_small_ hurricane. Irma has hurricane speed winds out to 75 miles/120 km from
the eye, which itself is 23 miles/37 km across.
Good luck.

I think it's one of those things where people have difficulties realizing the
_scale_ of things. For example hurricane Irma is the size of Texas or France.
If it hits Florida, people won't need to evacuate Miami, they'll need to
evacuate _Florida_. Think of the logistics it takes to evacuate a whole state
basically overnight, and the _size_ of a threat causing such event: if we
barely have the know-how to _run away_ in time, do you think we would have any
know-how to block something of that magnitude?

Should we stop hurricanes, even if we can?
Yes, hurricanes are destructive, especially to human settlements, but I'd be
surprised if there aren't massive ecological benefits to hurricanes in spite
of (or possibly because of) the destruction. Forest fires, for example, have
well-documented, long-term ecological benefits. Unfortunately it looks like
hurricanes aren't studied as much as forest fires.
Just doing some cursory researching online [1] [2], it looks like they
basically act as dramatic "flushing" mechanisms:
\- end droughts
\- distribute heat from the equator towards the poles
\- seed dispersal
\- redistribute soil/sediments along coastlines and inlane

How can we stop hurricanes? First, accept that climate change is real. Second,
act on it.
Year after year the global temperature increases and year after year the
hurricanes get stronger. All real climate scientists will tell you there's a
correlation.
~~~
oldandtired
Where do I start with this?
I have no issue with climate change being real. Anyone with a modicum of sense
can make those observations? However, your second point requires you to
believe in the "dogma" of only anthropogenic causes for this climate change.
At this point in time, we have no clue (and I mean no clue, irrespective of
what any "real" climate scientist might pontificate) about the extent of
actual causes of this climate change.
There may be (and I'm willing to give a small level anthropogenic causal
effect) some changes that mankind can do to mitigate possible effects of
climate change. They are limited and more in the line of defensive than
anything else.
And before you ask, No I am not a climate scientist. But my experience with
them is that when presented with specific questions related to the energy
requirements of their predictions, they refuse to not only answer the raised
questions, they will not dispute the energy calculations provided as a basis
to the questions.
I have done a series of calculations, in which you can do the same, based on
simple mandatory energy requirements that make the predictions of their models
simply laughable.
My basic view today is that if a "real" climate scientist says anything, I
will take that it that you had better check the silver draw to make sure the
cutlery is still there. At this point in time, I consider it to be more
pseudo-scientific than phrenology and I don't give that any regard at all.
And that is a pity, because we need some verifiable climate model will give
level of predictability. We have none at this time.
~~~
Vanit
Check out oldandtireds infallible series of calculations at
realclimatechange.geocities.com
~~~
oldandtired
Funny, ha ha.
If you actually took the time, about 2 to 3 hours of work and research, you
would quickly see that the various scenarios proposed by these "real" climate
scientists are a load of codswallop. As they say here at times, "Are you
smarter than a fifth grader?" Well a fifth grader can do the calculations with
but a little bit of help. If climate scientists were willing to call out their
colleagues over the various "unreasonable" scenario results then as a group, I
might be more inclined to give them a pass. But they don't, so no.
But so far, I have only had one person on the "anthropogenic" climate change
bandwagon who was willing to give it a go. To his merit and credit, he even
tried to provide a number of research studies to back his claim (he was not a
climate scientist and the papers he referenced are well worth reading). In the
end we agreed to disagree on our interpretations of the data presented. He was
much more clear and critical thinking than the various "real" climate
scientists that I have communicated with over the last two decades.
I have, over the course of nearly forty years, dealt with quite different
computer simulations and models and it is so easy to get them wrong, to the
extent that for some models, no matter what you put in, you appear to get a
reasonable answer out. They're the scary ones, people assume they are right
when in fact they are a load of rubbish.
If you were to actually try to do the energy equations, you would see this for
yourself. But obviously, you more interested in believing the anthropogenic
climate change dogma without at least some level of fact checking to test the
veracity of the claims. But that is up to you. We can compare notes after you
do your own calculations. Let me know when you have done them.
I am willing to give them a pass (or least a provisional move ahead) if they
can clearly show that the basic energy calculations I have made that are
required for their scenario outcomes are wrong in any significant way. That
is, the calculations are wrong by say 15 orders of magnitude or more.
Average worldwide temperature rises of a couple of degrees (Celsius or
Fahrenheit) do not appear to be able to supply enough energy to drive the
energy requirements. If they were, then these "real" climate scientists would
have been able to demonstrate this long before now. There would be an energy
process and pathway available to demonstrate this to all who wanted to see it.
As a number of people here have already shown, the amounts of energy required
for some of the existing events are just extraordinary. However, the energy
required to drive them is many orders of magnitude short of the energy
required to drive the scenario outcomes from the climate change models. This
is a problem.
Climate is a multivariate function of a very large number of interacting
processes. From the variations of solar output, the orbital position of the
planet around the sun, the axial tilt of the planet, position of the moon,
cloud cover, global land mass and water distributions, wind processes, storms
(from little rainbursts up to the likes of Irma), volcanoes (land based, ocean
based, ice based), forest fires (which you are getting right now), ground
cover or lack of it, flooding, oceanic algae distribution to a myriad of other
interacting effects and variables. To attribute climate change to
anthropogenic effects as the main driver is, well, unreasonable without
extraordinary evidence. Computer models that don't give reasonable, verifiable
predictions are not evidence, no matter how distinguished the climate
scientist may be.
~~~
cholantesh
Quite a lot of anecdota and question begging. Ho-hum.

oldandtired
I suppose there is a bit of anecdote, but then I generally find that
anthropogenic climate change believers won't take up the energy equation
challenge and so show that they are not willing to actually put any effort
into the discussion.
Climate change deniers and anthropogenic climate change believers don't appear
to have any inclination to do any sort of serious thinking about the subject.
Both appear to take a very simplistic political view about the matter and just
react along party lines.
Just as your comment shows little effort to even engage in dialogue.
~~~
cholantesh
Your original comment has nothing meaningful to discuss. You don't present
your data or analysis thereof, so we cannot discuss that. Here you call for
'serious thinking about the subject', but you engage in aggressive
strawmanning (believe in the "dogma" of only anthropogenic causes for this
climate change) and repeat the party line that climate models are all
unreliable (this is a long-debunked falsehood). These are non-starters for
meaningful dialogue.

Why not just harvest a hurricane's energy to weaken it?
~~~
SAI_Peregrinus
The small ones output on the order of magnitude of the annual power
consumption of the US in a matter of days. Where would you store the energy?
How? Even if you could get wind turbines that could survive it...
~~~
donjoe
Just been an overall question. There might be a solution no one ever thought
about. Why wind turbines? Kites could work as well. There might be a better
product not yet invented to solve the problem. It might be even better to
start at an earlier point by extracting heat from the oceans to lower
temperature and therefore avoid the formation of tropical storms at all. Just
some brainstorming ideas :)

How about coating the sea surface with a very thin layer of oil to reduce
evaporation?

Stop pumping excess heat energy into the atmosphere.
EDIT: While this won't stop them from happening, this is definitely not
helping things.
~~~
KGIII
That's not going to stop hurricanes.
~~~
nyxtom
It for sure won't, but it definitely isn't helping
~~~
KGIII
Interestingly, newer models are suggesting that hurricane activity will
decrease with global warming.
Basically, as the temperature rises, the colder regions will increase in
temperature the most - thus raising the global averages. Because of this lack
of heat disparity, less transfer of usable energy, there will be fewer
hurricanes and they think they will be weaker in general.
I'm on a tablet, but I can dig out the study (I think), if you want. Google
will guide you, otherwise. I was just reading this a month or so back. From a
physics viewpoint, it makes sense. Then again, I'm a mathematician and not a
climate scientist.

Decrease water temperature over a huge area that's constantly moving?

Lasers or magnets might work though...
~~~
candiodari
> Lasers or magnets might work though...
Actually if you can merely slightly resist the heat exchange that will kill
these storms just fine. 0.1% difference in heat exchange ? They're weakened to
the point of irrelevance. What would happen if we caused an oil spill on
purpose ?
We would need to create a circular oil spill where the air is going up (around
the eye), in a way that would slightly decrease (slightly is more than enough)
the heat exchange and thus the flow of air towards the eye. So an oil spill
surrounding the eye of the storm should kill the storm.
Of course the earlier you do this, the more effect it would have. You'd
effectively have to do it constantly to avoid having to do it for massive
storms.
Alternatively, you could nuke the air above the storm, or otherwise heat it
up. That would kill the reason for the funnel to exist (cold air relatively
low in the athmosphere on top of warmer water). The advantage I guess is that
you could decide to do this and it might kill the funnel in a matter of
minutes. We have nearly fallout free nukes nowadays (fallout measured in
grams, which when spread out over 1000 sq. km isn't going to do anything).
Of course, this would be climate engineering. If we were willing to do that,
we could easily have solved global warming by now. The issue is, what if it
goes wrong ? Who will seriously risk doing this, and therefore carrying the
responsibility afterwards ... Because we all know, nobody gets blamed for
doing nothing, and if you do something and fuck it up ... wow.

Ask HN: Were you saved by a teacher? - mathgladiator
In thinking about a recent comment I made ( http://news.ycombinator.com/item?id=2059752 ), i was wondering how many of us have been given second chances by teachers.<p>It seems to me, being entrepreneurial or a hacker requires dealing with a massive amount of daily failure. Yet, the school system is very poor at enabling this (which is probably why we can't teach entrepreneurial/hacking).<p>So, I'm wondering how many of us were saved by a fair or progressive teacher (as opposed to a crazy pedantic person)?
======
elliottcarlson
When I first moved to the states and started high school I was really bored
since everything we were learning was way behind the education I received back
in Europe. I chose to be a teachers aide in the language lab, conveniently
during a period there were no classes there simply so I could work on the
computers (already ancient mac classics and a single IIGS) where I got to play
around with Hypercard and attempt to make programs... I think that teacher let
me get away with a lot - and it was a huge learning experience since all I had
at home was a Compaq 8086.
On the other side of things, I worked for Seton Hall Prep school for a while
when I moved to the east coast - managing the network and maintaining various
systems including the community machines as well as the classroom machines.
While the machines were locked down quite well, and we even used a desktop
replacement, one of the students had figured that running Help from MS Word,
gave them access to MS Access (not generally something they had access to) and
the student was writing a pretty basic VBA application with forms etc on top
of Access. I managed to figure out which student it was and made sure he knew
not to do anything bad with it and I would be more than happy to help him out
and pointed him in the direction of learning more advanced stuff. I do wonder
if he is a programmer now :)

generating all the media buzz themselves?
~~~
nostrademons
They tell a compelling story that's interesting & new and fits in with the
zeitgeist. That's really all that PR is.
Right after I graduated high school, I worked for an all-teenage dot com. We
were a dozen or so high schoolers, ages ranging from 15 through 19, building a
"teen content" site with indirect venture funding (we were a wholly-owned
subsidiary of a venture-funded startup). This was the summer of 2000, at the
height of the dot-com boom. The NASDAQ had just peaked, but nobody knew it
yet.
We got picked up first by the local community newspapers, then the Boston
Herald, then the local TV news. Then we ran out of funding, but we continued
getting press inquiries for several months after we were technically out of
business.
We had a $20k PR budget (which we inflated to $50k whenever we talked to
people), but we never spent any of it. Instead, our (18 year old) PR guy would
just cold call newspaper editors with "Hi, this is Trip Guray, I'm at an all-
teenage startup called inAsphere.com, and we have a story you might be
interested in." If they weren't interested, fine, we'd say thanks for your
time and try someone else. If they were, we'd send them a press release over
e-mail or arrange for an interview.
Press coverage tends to snowball: if you get a story published in a community
newspaper, you're much more likely to get picked up by a major metropolitan
newspaper. If you get picked up by a major newspaper, other major newspapers
will go after you. If a bunch of newspapers are interested, TV will soon be
too.

The blog that the article was sourced from
([http://liesandstartuppr.blogspot.com/](http://liesandstartuppr.blogspot.com/))
currently has a biting post about how Theranos' failures are endemic in the
tech industry:
"Companies in the new tech area tend to be a little lax when it comes to doing
things carefully - Mark Zuckerberg, founder and CEO of Facebook, tells us all
to "Move fast and break things", which I have to agree is a great way to
innovate and learn _when your product does nothing of actual importance at
all._ It doesn't matter if you don't get your silly cat videos, or can't post
pictures of your holidays, because your business payroll doesn't run on it,
your medication isn't delivered by it, nor is your aircraft navigation based
on it. Real consequences of a Facebook blackout are near zero."
"[...] In both these industries [generator manufacturing and medical
ultrasound] the mentality was "we must make sure this is safe" and the idea of
reducing or skipping safety is never considered, but I do not see the same
thinking in many of these tech companies. I have literally heard "what's the
minimum we have to do?", "we don't have proof it's a risk", "that sounds time-
consuming and expensive. We should do <pointless but fast/cheap thing>
instead", and "well if it goes to court our lawyers say they have good
arguments"."

uBeam is most likely vaporware that violates the laws of physics - at least in
what they propose on a product level - but that doesn't mean that they
shouldn't be funded to try working on a really hard problem. Maybe in their
R&D they fall short by a large margin on the product side, but still make some
meaningful contribution.
I think where everyone loses their cool is when the company purposely gets
massive amounts of PR to glamorize themselves (and their founder) as if it's
already a success [1]. IMO these guys should be keeping a low profile, like
the people working on Jetpacks and similar things. Make some noise when you
have a demo.

uBeam claims to be using ultrasound to transmit power, while the other
companies (inluding the one you mentioned) in this field are using radio
waves. Electricity over radio waves is well understood and basically works.
The problems there are ones of engineering a system that is sufficiently
energy efficient and reliable in a reasonably compact package rather than any
fundamental scientific problems.

that the FDA is a sham and I honestly wouldn't care if they Theranos didn't
pay extra to have some peer reviewed paper published or adhere to the laws
proposed, written, ammended and passed by people without degrees in the field.
It is a shame Theranos did some questionanable, unethical & likely illegal
things. I wont hold them up as the Unicorn's gift of Zeus here, but I really
could care less about red tape. 23andme had an injuction against them by these
clowns(fda) so unless soneone here can say in 2008ish 5 years after Theranos
was founded, you knew it was going to implode, then I would say would you
still not want another company in the space to get funded? Nobody gets points
for standing infront of Yahoo right now and sayibg they are in bad shape,
shits obvious. However there are many companies succeeding where Theranos
failed.
As for uBeam, I assumed this would fail. I just looked at it like a privately
funded research project. Regardless, it seems like this space is actually
succeeding (just not uBeam wireless inplementation) so I am excited about
that.
tl;dr it's really easy to be negative with a decade or more of hindsight. sure
these were collosol failures & that money could have been spent elsewhere, if
nothing else these high profile companies likely inspired some competitors and
interest in the space and many of them aren't doing something physically

Loop Unrolling - bpatelcse
https://www.cs.umd.edu/class/fall2001/cmsc411/proj01/proja/loop.html
======
barrkel
I had an amusing time optimizing a byte-scanning loop in Java a few months
back.
The initial loop was a lot slower than a naive byte-by-byte, non-unrolled
version in C. I implemented an approximate version of Duffs device, and did
the unrolling by hand, improving it by a good 50%. But it was still much
slower than C.
On a whim, I went back to a naive loop, but simplified the core. This was
strictly speaking algorithmically more costly, but it hit a JVM optimization
code path specifically tailored for searches through byte arrays. Suddenly my
code was about 40% faster than naive C (still run through gcc -O3)! A peek at
the disassembly showed the JVM had done all the relevant loop unrolling
itself.
A key part, IIRC, was something to do with the loop bounds check; it was
simple enough to be proven to always be less than the array length.
But it did feel a bit like stumbling around looking for a magic incantation.
Tools like manual loop unrolling, while they help, still incur relatively
heavy costs in array bounds checking that you can't easily escape.
If I ever have to write a loop like that in the future in Java, I'll start out
with the simplest loop, measured in a micro-benchmark, and try and iteratively
modify that loop to the final implementation without losing the sweet spot of
JVM optimization. Doing it from this direction is much easier than the
reverse.
~~~
vardump
Can you show your byte scanning code in both Java and C?

Loop unrolling is mostly unnecessary on modern pipelined out-of-order
execution CPUs. It can even slow down execution due to heavier pressure on L1C
cache.

I used to volunteer teaching English to Chinese kids from migrant families
(displaced within China). One of the ways I illustrated the value of English
was to print several objects of differing size. Those sizes each represented
the average salary of a given profession in China. Then I had a piece which
would nest on top of that object that showed the value of English- the
additional salary an English speaking Chinese professional in that field could
expect. The physical, tactile experience- objects of very different sizes with
variables they could manipulate with their hands really got the point across
in a way to those kids that graphs never did.

An interesting idea, but it may be short-lived. They're essentially using a 3D
printer as a poor man's 3D hologram system. Very nice application of the
technology, but once we commercialize actual holograms it'll be obsolete - in
much the same way slides were replaced with monitors.
~~~
carb
I think it's more likely that AR or VR will be used for this purpose. It's
already pretty trivial because they've already created the 3D model
representing the data, all they have to do is throw it into a game engine.
~~~
chton
AR and VR still aren't quite as convenient as a real 3D model you can walk
around and point at. The technology isn't there yet. But it's true, once it
reaches that point it might be used for this and would replace the 3D-printed
models even faster.
~~~
ObviousScience
But AR and VR get you one more dimension (time) than a 3D model and are much,
much, MUCH easier to produce a large display from.
------
placeybordeaux
I completely fail to see how big data comes into play at all. All they mention
is that the use geo tagged twitter that that is specific to MIT. I don't that
visualizing a well defined subset of data on a 3D space was really related to
the problems presented by 'big data'.

Ignoring the Wiggles - loyalelectron
http://themacro.com/articles/2016/02/ignoring-the-wiggles/

trjordan
I'm sitting at SaaStr Annual, a conference with predominantly SaaS founders,
sales & marketing types, and VCs. There's a lot of talk about the recent
motion, especially among VCs.
One of the things I'm struck by is not that the wiggles actually matter, but
sentiment matters. Because it's a frequent topic of conversation, it's an easy
thing to bring up, and without some knowledge and context, it's a strike
against you. Does that matter to your business or your clients? No. Does it
matter to the person you're talking to right then? A little. And if you're
trying to get them as a customer or advisor or mentor or whatever, you're a
bit more in the hole, because you chose to ignore the fact they're thinking
about the wiggle. It's not important to you, but it's important to them.
So don't focus on the wiggle, but don't ignore it. Internalize what has
changed, respond appropriately, and know that you can move past it.

The difference between long-term investors and startup founders is that no
sane long-term investor puts all their money and resources into one asset.
Startup founders do not have diversification or a fallback, and it's humanly
fair for them to be concerned when things are on a serious downtrend with tech
stocks.

A young Warren Buffett had 75% of his allocation in GEICO.
If you're _certain_ something is going to go up in the long term, it makes
sense to buy as much of it as you can. You must be certain, and you'd better
be right about being certain.
A Buffett-favored aphorism: "Too much of a good thing is wonderful."
If your goal is substantially different performance from a market average, a
concentrated position is the ticket. But, unless you're really good, the best
you'll do, on average, is average, in which case you'd do better by buying an
index.
~~~
tyre
His GEICO investment was about more than just him believing in GEICO. It was
much more brilliant than that.
Insurance companies are wonderful to own because you get access to their
capital. They have tons of floating capital that's held in reserves, from
premiums, until it needs to be paid out for claims.
GEICO was a perfect investment for a young Buffet because he exchanged cash
(liquidity) for _even more liquidity_.
~~~
dripton
Young Buffett didn't buy GEICO, the company. He just bought some of its stock.
So he didn't get any extra liquidity.
Older Buffett bought the company.

Microsoft's forthcoming Minecraft Education Edition is written in C++ - ingve

======
sheepdestroyer
Micro optimized by John Carmack himself who volunteered (he was like a free
consultant for while) for the task because he believed that's the best that
could be done to help VR. He first had to personally persuade both hierarchy
at FB & MS. So bold.
From : [http://venturebeat.com/2015/09/24/how-john-carmack-
pestered-...](http://venturebeat.com/2015/09/24/how-john-carmack-pestered-
microsoft-to-let-him-make-minecraft-for-gear-vr/) :
“I was willing to do just about anything,” he said. “On the phone I said that
if this doesn’t happen, I’m going to cry. This will just be so terrible. This
will be the best thing that we can do for the platform. But there are some
problems that compilers can’t solve.”
It turns out that the solution was to get the top executives from Facebook and
Microsoft together.
“Mark [Zuckerberg] and Satya [Nadella] were able to sit down and make sure
that the deal happened,” said Carmack.
~~~
Almaviva
I think he may be the best refutation against people who don't believe in 10x
engineers. Imagine you want to create a VR prototype and get to hire 100
average programmers with some experience in the industry, and you're up
against Carmack with a month until your demo...
~~~
untog
I don't think people disbelieve that 10x engineers exist. Just that 98% of
those who claim to be one are wrong.
~~~
espadrine
I disbelieve.
That said, I don't contend that some people are not at some point 10 times
more productive than others. I contend that anyone can be just as productive,
and often are, were or will be, although the manner in which they should be
productive is absolutely not clear-cut. Society as a whole shapes how we act.
Diversity in its composition allows what we rely upon.
For instance, I would not be as productive at work if I had to take care of a
few children on my own. Similarly, I am extremely unproductive while
gardening, and don't intend to spend the time to improve.
~~~
eloff
You're practically coming out and saying that all humans are equal and the
only productivity differences can be attributed to other factors. That's a
ridiculous position to take.
~~~
adventured
And _extremely_ easy to disprove at this point with brain scans vs
capabilities. We know enough about the brain now to understand that some
people are born with advantages (or disadvantages), whether that's in memory
or social skills.

ChuckMcM
I chuckled at this: _" In schools and colleges that use Office 365, students
will be able to log on to Minecraft using their Office credentials."_ Because
everyone things "how can I log into this game? Oh yeah, with my _office_
credentials." :-)
That aaid, one of the more interesting debates I participated in at Sun was
Bill Joy's insistence that interpreted Java would be "faster than C++." From
what I recall of his argument, it was that understanding the semantics of the
program and just in time compilation would allow the JVM to run only the code
that was needed in a smaller resident set with fewer context switches. At the
time I was arguing against that, saying that a compiled version of Java could
be a useful systems language but the interpreted version would not.
And even with some really really amazing hotspot technology on the JIT
compiler, I don't think Java was ever faster outside of a few synthetic test
cases that did no useful work.
So it really doesn't surprise me that a C++ version of minecraft would out
perform a Java version, but it would be much more interesting if they included
a JVM for the mods, so that the core was fast and the mods were portable.
~~~
pnathan
To be honest, a lot of people have slammed the Minecraft codebase, claiming
it's badly written and kind of a slow mess. I can't recall the citations, but
based on the discussions when I read those aspects, I wouldn't put aspersions
on Java alone in this case.

It was a one-man hobby project turned into one of the biggest video games. I

As other people have pointed out: "Modding" in Minecraft is literally
replacing the original Java bytecode with your own. This is why the idea of a
Minecraft launcher took off; replacing binaries with modified versions is very
dirty and very difficult to do if multiple things are touching the same file.
I hope that this C++ version is the impetus needed for the forever-promised-
never-delivered modding API to finally take shape. Then I don't even care what
the underlying technology is.
~~~
madaxe_again
One would hope so - I predict however that many end users will be slow to
adopt as modders will probably start by rioting, and then replatform (if
indeed there is an API) - but there will be a substantial time lag. There's a
potential for a vicious underadoption cycle there, however, and bifurcation of
the community into "classic" minecraft and "new" minecraft.
~~~
kuschku
Oh, don’t worry, we are already rioting.
Mojang already announced that "deep modding" won’t be supported. They’ll
extend the stuff current resource packs can do, but they want to avoid modders
replacing or extending any game mechanics directly.
For example, modifying the rendering pipeline will be impossible.
What modders expect: Minecraft as a whole engine, similar to the API Unity
presents to developers.
What Mojang is willing to deliver: A modding API that’s glorified command
blocks.

Assuming MC does move to a C++ main version:
I wonder if anyone is studying this and drawing parallels to the Python 3 or

* Existing product is great, but limitations are being encountered
* Decision is made (or reality admitted, depending on your view) that you have to make a dramatic change
* Community is split, progress is slow
* ???
I'm a huge Minecraft fan (it's about the only computer game I regularly play),
and while the community has lots of grump people, it's also fairly adaptable.
This would be a huge shock though, and I'm more interested in what happens

On the other hand, this potentially could unite XBox, mobile and PC versions

ressource packs and other vanilla tools.

Tekkit client, Curse client, and FTB client. If the mod isn't on one of those,
they aren't getting it.
I use to do custom installs of mods and even a little bit of patching to make
mods play nice together (namely recipe conflicts), but the time it takes just
isn't worth it when you can grab a Direwolf20 or Tekkit pack and play right
away. I do kinda wish Mo Creatures was still included in packs because my
little sis loved the horse breeding to get endgame horses.

mjevans
You forgot about the atlauncher. It has some interesting packs like
TechNodeFirmacraft (a TerraFirmacraft based mod pack) that actually somewhat
educate users about rising up from caveman to industrial era technology (real
metallurgy names and semi-believable progression; at least until the end game
where you make fantasy alloys to move blocks of non-finite water and lava
about).

Why would it be more work? You've already learned what work and what don't

My 11 year old son is an avid Mincraft player. His favorite aspect is playing
team games on multiplayer servers.
When I told him that Microsoft bought Mincraft, he was quite upset, and was
confident that Microsoft would ruin it.
Change was bound to happen. Hearing their plans to go c++ makes me wonder how
it will impact the server ecosystem. Also, the "Windows 10" messaging in the
article does sound like a case of a big company trying to bend a community to
its own will (get people on Windows). In my son's case, if things go south, he
is going to end up hating Microsoft for ruining his favorite game.

On one hand I'll be happy to not have to keep Java on the school machines,
with its terrible installer, and minecraftedu, which wants to write to the
install dir (same problem with kerbaledu, but that also has the additional
crapness of being licenced per machine based on mac addresses, requiring
delicensing, and internet access to check licence).
On the other per year per user fees for software is a terrible trend,
especially for schools. And I'd rather run my own server, and the kids love
the mods.

Lawtonfogle
Well, I was wrong. I was fully expecting the rewrite to be in C# to get the
Java people to switch to C#, not in C++.
~~~
leetNightshade
Switching from Java to C# doesn't offer any HUGE advantages to the end user.
Switching to C++ does, granted with some drawbacks depending on how mods are
handled, if they're going to be portable or not.
If Microsoft is only making a Windows version of Minecraft, then they don't
have to worry about the portability of mods, which would be a shame.
~~~
Lawtonfogle
>Switching from Java to C# doesn't offer any HUGE advantages to the end user.
I know C# doesn't offer much in terms of optimization.
I was thinking they would do a C# rewrite because getting modders to switch
from Java to C# is easier and it would give them a chance to show support for
C# on non-Windows systems. I also think it would reduce the chance for a
community split where modders continue modding the last Java versions.
I'm probably biased in favor of modding. I remember Notch mentioning most
sales came from systems where modding wasn't even possible, even though I
personally think modding is the greatest thing about Minecraft. That has
likely biased my view on the issue.
------
Kequc
If anything needed a re-write Minecraft needed one. With the resources
Microsoft has at its disposal I'm surprised to see it looks like a 1:1 remake.
They didn't update the visuals or anything.
This was an opportunity to release a slightly upgraded version of the product.
It isn't backwards compatible so why keep for example all of the redstone bugs
and so on, in it? This product could have been greatly refined. Maybe that's
only coming in Minecraft 2.
In true Microsoft fashion, there will now be Minecraft, Minecraft EE, and
Minecraft 2. Instead of just two major products.

I feel like MS will probably do well on this, it's essentially a developer
tool (for all ages), and MS makes plenty of those just fine. They clearly have
good people involved and are using C++ so you know it's a performance oriented
mindset (since Java vs C# is certainly close enough to make a C# version
passable).
I wouldn't be surprised if this is a success.

Can a company actually be sued for following a court order? Is US culture
_that_ sue happy?
They refused to give up any information until a court ruled that they must, at
which point they complied as expected. Does the lawyer in question really
intend to make it the company's responsibility to determine which court orders
are unconstitutional and which are not?
Is that really the precedent he/she want's to set? My oh my.
~~~
zngtk4
You can actually be sued for _anything_. Whether or not you can win is another
matter, and it's difficult to recover legal costs for a frivolous lawsuit. The
lawyer is probably just hoping for a settlement.
~~~
run4yourlives
Is there not some office that at least validates the merits of the suit
though? Otherwise, the legal system can pretty much be used as a tool for
extortion no?
(I'm Canadian here, so excuse my ignorance)
~~~
mikeryan
No.
The closest you'll get is that very few lawyers will take your case if it
completely sucks. And it can get thrown out pretty much off the bat from the
the judge
Criminal cases do have grand juries which weigh the merits of a case before
going to trial.
~~~
run4yourlives
So theoretically, an organization with large enough pockets could literally
destroy a competing organization with lawsuits designed only to ensure the
victim expends large amounts of cash on legal fees, correct?
I'm wondering if this method of "business" has ever been attempted?
~~~
PotatoEngineer
When the Golden Gate Bridge was being built, the ferry companies (who would be
put out of business by the bridge) tried to sue the bridge to death with
something like 2000 trivial lawsuits. While each of these was easily defeated,
the only thing that stopped the ferry companies was that the local populace
boycotted the ferries until they stopped the lawsuits.
So yes, it's been done before, is probably being done now, and will happen
again. You can counter-sue trivial lawsuits to make the plaintiff go away (and
stop filing suits against you), but it takes some work and laying out some
money to lawyers.
~~~
run4yourlives
Thanks for the background. This whole thing strikes me as a horrible loophole
in the legal system. I'd imagine the same is true in most western countries.
~~~
electromagnetic
Sadly it is the same in most western countries, however if you sue me because
I wore a pink hat (frivolous lawsuit) I have the right to counter-sue you
(which would be a non-frivolous lawsuit). Yours would be thrown-out and cost
you money and probably a lot to get a lawyer to take it on, mine however would
likely be taken on on a no-win-no-fee basis by basically any lawyer because it
would be so easy to win. So your suit would cost you money, and mine would
likely cost me nothing or make me money.
So yes the loophole is there, but the loophole itself is kind of self
destructive for anyone dumb enough to try it.
~~~
run4yourlives
Yet the example you gave would have been successful had it not been for
outraged civilians mounting a boycott.
How many issues are being exploited that don't warrant such public outrage? My
guess is more than a few.

======
andreaja
Is it just me or are people blowing that "$50b" valuation of facebook out of
proportion? And applying P/E * Profit to other companies doesn't really seem
like an interesting metric, especially when comparing it to well-established
companies. Buying Facebook shares right now at 100 P/E seems like a long bet
that absolute profit will improve within the next N years (where N is some
acceptable length of time for the investment). That's all. The $50b valuation
is _obviously_ (to me anyway) not based on current numbers, but expected
future numbers.
The amount of indignant disbelief going on is amazing. I would understand this
if the OP's money was being invested against his will, but when GS and others
are making this bet with their own (or their trusting clients's) money,
where's the problem? Are people angry at FB for being popular?
~~~
yoseph
Hi andreaja,
Thanks for the response. I'm the author of the article (Macco, thanks for
submitting it!).
You're right that the $50B valuation isn't based on current numbers. It's
based on what Facebook _might_ be able to do in the future. Imagine you were
buying a house. It's a great house, has a solid foundation, beautiful
interiors, and is in an excellent neighbourhood that is constantly
appreciating. Would you pay what it _might_ be worth in 3 years, today?
I understand the argument about growth, but even from that end, it doesn't
completely stand up. If we were to use the PEG Ratio
(<http://en.wikipedia.org/wiki/PEG_ratio>), for Facebook to be fairly valued
at $50B, it has to grow its Net Income by 100% annually, on average over the
next five years.
It's possible Facebook might be able to do that next year, but then it'll have
1 billion users. That's 14% of the world's population. That's huge. Being
generous though, let's extend that 100% growth into the year after. Then,
Facebook would have 2 billion users, 28% of the world's population, and
assuming current margins, they would only be eeking out $2 billion in profit.
Will it be worth $200 billion then? I would say no and I would say Facebook's
not worth $50 billion now.
~~~
semanticist
Facebook's income doesn't need to grow linearly with their number of users.
They could, instead, look at ways to make more money per user.
Since they've been spending their time until now focussed on getting lots of
users, I'd imagine it's safe to say that they could increase their revenue per
user well beyond what it's currently at.
~~~
yoseph
I hope, for the sake of current investors, they find other ways of monetizing
users. But my example is intended to illustrate the overvaluation based on
present methods of monetization.
Nevertheless, I don't think it's a safe assumption that they could increase
their revenue per user well beyond its current level. Generally speaking, it's
pretty tough for free services to monetize themselves. The only routes seem to
be ads & taking a cut of revenue from apps that run on its platform.
Facebook would really have to pull a rabbit out of its hat to increase its
revenue per user well beyond its current level. It's certainly not a safe
assumption.

This is not an appropriate use of a PE multiple because different companies
have different growth rates at various stages. The earlier the life cycle, the
higher the PE given potential growth later on is much higher. This post is
actually pretty misleading and gives people the wrong idea about how PE
multiples should be applied.

You're right that different companies have different growth rates at various

Neither P/E, nor PEG are useful metrics when dealing with a young growth
company.
Consider this: There was a time when Yahoo! had many potential customers and a
substantial business and technological lead over the competition, but no
positive earnings. The same was true more recently of Genzyme, currently a
multi-billion dollar biotech company. Would it be reasonable to assign zero or
negative values to such companies? Of course not.
And what happens when a high-tech growth company climbs up from a small
negative earnings to a small positive earnings? Suddenly instead of having an
undefined P/E, they have a very high P/E. This is reasonable. A solar power
company with 500m in sales and 1m in earnings that had 200m in sales and
hugely negative earnings in the previous year could very well be worth over a
billion. If the market gave it such a valuation, gawking at its P/E of 1000,
and then applying the same P/E to an established company like Kraft would just
be a waste of breath.

I believe the valuation that Facebook is running on is predicated on an
expectation of sustained future growth. Apple is a fast growing company, but
I'm not sure that you can expect them to continue to grow at their current
rate for as long as you can expect facebook to continue to grow at.
The Smartphone market is growing very fast, but Apple have competition in this
market now that Android has started to grow. I'm not saying Apple are loosing
much marketshare, more than while a year ago it looked like they going to gain
marketshare in a market that was growing, while now they are holding their own
in a growing market.
Facebook doesn't really have any serious competitors - myspace has slowed in
terms of growth and is possibly shrinking while linked in are aiming at a
different market. The only thing even on the horizon that could undermine them
are federated social networks - and its far from proven that they are what
consumers want.
Its a high valuation and does smell like a bubble, but I wouldn't be surprised
if Facebook hit $100 billion when they IPO assuming they can get to a billion
users by then.

P/E should not be considered in a vacuum. The high valuation probably exists
because there is a large expectation of earnings growth. I don't know if we
can eyeball a PEG on FBOOK yet as we don't have the proper data but it's
probably much different than AAPL (and especially T!), at least in the eyes of
the investors.

Some relevant thoughts:

* Chinese market - without it Facebook will need to expand interplanetary by creating colonies on Moon and Mars.
* I think with 90% probability, that there will be another opportunity to buy FBOOK shares under $50B valuation after IPO (movements in public stocks are 80% general market sentiment and only 20% company performance).

My understanding was that pages which are inherently non blocking could be
blocked due to the use of shared threadpools and by default leveraging the
same execution contexts.
I would love to understand if this is a problem in practice, or if there are
other practical implications.
~~~
anorwell
It's definitely a real, common problem, but I think the article obscures it a
bit. Blocking I/O operations using the Akka dispatcher will block that thread
while the command executes. Doing this too often will cause all the akka
threads to be blocked, stopping the dispatcher from processing more events.
Therefore, one should avoid performing blocking operations on akka threads.
In my experience, one of two things will happen in practice:
1) You use an asynchronous library for I/O calls, which will maintain its own
threadpool. This is no problem, because the I/O threadpool is independent from
the akka theadpool.
2) You want to use a synchronous library that performs I/O operations using
the caller's thread. If you must do this, you should use a separate threadpool
(ExecutionContext).
------
papsosouid
Why do people still continue to push the myth that using event driven style
with callbacks and a huge unmaintainable mess is the only alternative to
native threads? Userland threading has been around for a very long time. The
only difference between using an event driven style and using a userland
thread lib is that with userland threading the complexity of managing the
state of the various computations is done by the thread lib instead of by you.
The sooner people stop promoting the false dichotomy, the sooner people will
realize every language should do concurrency as well as haskell, and the
sooner that will actually happen.
~~~
xyzzy123
In practical terms what happens is that your clients need to have a real good
mental model of what will block and what won't.
Also it turns out event driven programming is fine when you do it, but wait
'till you have curl handles and say mysql handles and blah 'andles and foo
andles. Fork andles!
Threading sucks. Mixing event loops also really sucks.
The developer centric way of doing it (e.g. screw performance I just want it
to be correct and look nice) is really to flip to message passing and separate
"logical processes". That's our unfortunate state of the art.
EDIT: I didn't mention that I think all the userland threading libs I know of
are crap. Which ones do you think are good? P.S I'm not going to be sarcastic
or critical about it, I would really like to have portable, usable LWP in C or
C++.
~~~
rdtsc
Both suck, but I'll take threading (acutally I'll take Erlang's processes the
most) but if I had to choose between the two, I'll take threads.
> but wait 'till you have curl handles and say mysql handles and blah 'andles
> and foo andles. Fork andles!
Yup. If I have an event driven program can I use another library that is not
built on the same event driven framework?
The answer is usually no. Even if it has the nice internally composible
"futures/deferreds" feature.
An operation that is non-blocking will return some kind of a
future/promise/deferred thingy. Those bubble all the way to the top through
the API. It means you need to have 3rd party libraries and support code that
knows about them.
This is the case with Twisted (which is a nice framework) but it means having
to have a parallel universe of libraries for everything (because they have to
return deferreds or being able to be passed in deferreds).

Approaches to providing affordable housing for non-profit workers - panic
http://brewster.kahle.org/2020/06/28/results-of-7-approaches-to-affordable-housing-for-non-profit-workers/
======
rayiner
We are having some important conversations about equality these days, so I
think it’s worth bringing up this point. The notion of subsidizing housing for
non-profit workers is concerning. While many non-profits deal with problems
like homelessness that overwhelmingly victimize people of color, non-profit
workers themselves are overwhelmingly white. Much more so than the workforce
as a whole: [https://communitywealth.com/the-state-of-diversity-in-the-
no...](https://communitywealth.com/the-state-of-diversity-in-the-nonprofit-
sector). Moreover a large fraction of revenues (for example, 65% for “human
services” non-profits) comes from the government, so it’s taxpayer dollars
that are paying for people to live in San Francisco and would be paying to
subsidize their housing.
This is one reason why people are interested in things like UBI. It seems
perverse for the government to use taxpayer dollars to say combat homelessness
in San Francisco (the supermajority of whom are black, Hispanic, or multi-
racial) only to have much of that money go to paying salaries for mostly white
college educated people. Of course, non-profit workers of all ethnic
backgrounds can be tremendous value-adds. But when we’re considering whether
we want to subsidize housing for those workers, it’s worth stepping back for a
moment. There is a lot of money on the line: even excluding universities and
hospitals, non-profits spend $750 billion annually, more than the US military.
When taxpayers spend money out of a desire to help certain groups of
people—especially now that we are becoming more aware of the disproportionate
impact of things like homelessness on certain groups—we should strive to make
sure that the money helps the people taxpayers think they are helping.

One thing I think about non profits and volunteering, is the jobs displaced by
volunteers; For example; Adopt-A-Roads
In "The Legend of Bagger Vance", Hardy's dad becomes a street sweeper in the
midst of the depression to pay his bills;
What if, instead of volunteering to clean up roads, the city collected taxes,
and paid a living wage with benefits to people cleaning up the streets.
This line of thinking also applies to the Coronavirus, restaurant + school
shutdowns; If only, instead of asking for volunteers, non profits were paid by
the state to re-employ restaurants and/or their workers, to make meals for
children now without a meal.
~~~
rayiner

> streets.
Viewed through the lens of equity concerns, I worry that the result of your
hypothetical is a bureaucracy of unionized, mostly white college educated
managers overseeing the street cleaners.
My hope is that recent events make us think hard about the nature of need in
America and how we address it. Over 90% of white people are above the poverty
line. The median income of a white household is $70,000, versus $40,000 for a
black household. 60% of all homeless people are black or Hispanic. We talk a
lot about middle-class "stagnation." But _median_ wealth for white people has
more than doubled, after inflation, since 2000. It hasn't budged at all for
black people.
More than ever, we are recognizing today that a huge part of systematically
addressing poverty in America is about addressing race disparities. That’s
critical: the black-white income gap (at the median, so forget about Jeff
Bezos) is proportionally the same size today in 2020 as it was when George
Wallace ran for President in a segregationist platform. Meanwhile, we have
spent vast sums on the premise that the best way to remedy racial disparities
is through government programs for education and creating “good jobs with
benefits.” State and local spending per person has therefore doubled since
1977.
But it turns out that much of that spending merely perpetuates those gaps. For
example, increased education spending (which has tripled in inflation-adjusted
dollars per student since 1970) has overwhelmingly gone to white, college
educated teachers and administrators. (Indeed, black people were actively
excluded from many of these jobs by unions.) Cities with majority black and
Hispanic populations owe hundreds of billions in retirement and health
benefits to retired teachers, police, etc., who are overwhelmingly white.
Now, that’s not an argument for saying that we should, for example, renege on
those obligations. But we certainly shouldn’t perpetuate the disparities. If
we are appalled by say homelessness in American cities (and we should be), we
should figure out how to efficiently channel money to homeless people or
people likely to suffer homelessness. Not to some government bureaucracy which
by its nature is likely to be staffed with people who have various indicators
of privilege (white, college educated, from a middle class household—who do
you think government agencies tend to hire?)
~~~
HouseOfLard
> we should figure out how to efficiently channel money to homeless people or
> people likely to suffer homelessness.
Governments entail some degree of bureaucracy, much the same way that
corporations require some degree of management. It's a question of balancing
that overhead with actual results.
Civil services need to better align with making a meaningful impact. More
focus on the actual impact of civil services, and less on aggregate budget
allocation.

Another attempt that doesn't address the real issues: rent is too high and/or
wages are too low. In-demand locations are always going to be expensive.
The minute you start providing "special" apartments to a certain group of
people you introduce tons of other (negative) issues. That person is basically
locked into that apartment and can never move. Any issues with quality or
landlord disagreements will be tilted towards the owner, because they know the
renter will never leave. The whole thing is a mess.

Greedy renters is not the reason here: in the original article the author
considered building a house for workers on the company land. But that turned
out to be too expensive.
Building houses and maintaining them in livable condition is not that cheap.

> Building houses and maintaining them in livable condition is not that cheap
I don't really understand this. Building and maintaining houses (especially
single-family houses) is really cheap. (We're talking like ~$600/month or so
for a large 4-bedroom home).
The expense in housing is primarily financial shenanigans and land
monopolization, with some property taxes on top. Actually building and
maintaining a house (construction + maintenance costs) is way less than 50% of
the total cost.
~~~
AlexTWithBeard
Please see the original article where the author explicitly complains that
cost of building their own house is too high.

I've never understood the logic in these programs. People either think they
can something for nothing or that they can fool others into believing that.
Pay people enough to cover their needs, or accept that we don't want them to
do whatever they're doing.
Weird systems where you subsidize peoples rent but you won't pay them cash
just end up forcing them to spend more on housing than they want. So you spend
more than it would cost in cash and they're less happy than if you just paid
them. So wtf is the point!?
Plus housing gets very sticky. People get very upset if they are required to
move just because a program ends or they go part time. If an area gets more
expensive, you have to (rapidly) increase the subsidy, if it gets worse you
lose all your employees. Making your employees move house every time they want
to change jobs is very anticompetitive
Programs like this are also opaque and hard to value. I knew a teacher who
thought she was getting free rent up to X, but the small print said it was
actually 25% of rent up to 25% of X. I actually think this is why providers
favour these schemes: they're deceptive.
All this so that... We can avoid paying people what they're worth, and being
honest about what that number is.
~~~
s1artibartfast
You make some good points, but the logic is pretty clear from the employers
point of view. It might be helpful to think of it as analogous to supply chain
integration. One advantage is decreasing overall costs by cutting out the
middle man. If a property owner is making money on your company’s worker, you
can save that much by doing it yourself. Another advantage is supply chain
security. If The market rent doubles, your won’t go out of business.
------
opportune
We should not continue shoveling any money into “affordable” (read: subsidized
if you win some lottery system) and instead need to focus on reducing the
market rate rents. The whole “affordable” and “subsidized” housing system is a
scam to sell $10 for $3 to a few lucky souls without addressing the root cause
of the problem
Furthermore nobody should feel entitled to live in SF proper. It is easy to
commute in from much cheaper areas in Alameda and Contra Costa counties, and
it doesn’t make sense to subsidize some small set of people to not make that
commute

The housing supply has been very inelastic in the Bay Area. And every business
and individual who wants to be here starts out life short on housing. So I
would group his approaches to staying in the Bay Area into three main
categories:
#1, #6: Cover the short by hoarding enough of the fixed amount of housing for
yourself and taking that out of the market.
#2, #3, #4: Help employees cover their short. I think it is smart that of him
to try to do so in a targeted way to help new employees with downpayment and
loans rather than ratcheting up everyone’s salary.
#5: Build more housing. This is the positive sum approach. I wish he
elaborated on this because there are many roadblocks to San Francisco’s
failure to convert high incomes into more housing (zoning restrictions, slow
entitlement process, high fees, high construction labor costs), and it would
help for more leaders to be part of the conversation on how to solve these
problems for everyone, not just for his own nonprofit.
~~~
AlexTWithBeard
Or may be we should face the sad truth: it's only so many people can be
accommodated in SF.
Granted, we can build taller houses. It will cause huge influx of people,
transport collapse, school and health care systems overload.
At this point it may be easier to just build another city.
~~~
opportune
This makes my head boil.
The Bay Area can also build more of those schools and infrastructure as well.
There are so many metro areas, probably hundreds, that have done it before.
It’s entirely a political problem. I always hear the NIMBYs complaining about
these made up problems and _other people_ choosing to live in “shoebox
apartments” as if they’re real problems and not simply them imposing
restrictions on everyone else
~~~
AlexTWithBeard
You are absolutely right: NIMBY.
Apparently due to some reasons local people do not want to live in a beehive.
Go and build somewhere else. California is a large state with lots of
unoccupied land.
~~~
opportune
I’m saying the problem needs to be addressed in good faith, because NIMBY
people will put up nonsensical arguments like other people living in small
apartments or needing to build new schools (to support an expanding tax
base...) as problems rather than the actual problems they have motivating them
to politically oppose urbanization
~~~
AlexTWithBeard
You are solving the wrong problem. No matter how hard we try there's no way to
squeeze all the United States in SF.
May be instead just make other places livable?

The Bay Area _could_ host the entire population of the United States with ~850
sq ft of land area per person.
As it is, we currently allocate ~29,500 sq ft of land area per person.
Surely we can find a middle ground somewhere in the name of access to
opportunity and in the name resolving our severe housing shortage.

I feel remote work is the most viable solution that was listed. It works
around the problem of limited housing inventory. In addition, it helps the
environment.
~~~
nutshell89
When talking about the environment, I think it's useful to think about what
remote work would mean at scale.
Non-profits in SF often work directly with vulnerable populations, take Larkin
Street Youth Services, for example. their mission directly involves
interacting with homeless youth on the streets. San Francisco-Marin Food Bank
is basically a giant warehouse in SF.
Even if you do have no-profit work that can be done over Slack or Zoom, these
are still people who'll commute to the beauty parlour, buy groceries at the
farmers market, or visit the museum during the weekend - so there are still
excess car trips while living in the suburbs versus the Sunset District.
~~~
chaostheory
Any reduction in the commute is a net positive for traffic, the environment,
and even productivity.

Sure, not everyone can work remotely. However, even they will benefit from the
reduced traffic and commute times.

You're not seeing the bigger picture. Not everyone lives in the Bay Area. With
remote work becoming an integral part of office culture, this also means not
everyone has to work in the Bay Area even when they work for Bay Area
companies. ie. They're not going to go to Sunset on weekends; everything is
more decentralized. Remote work scales better than just throwing money away
when you can't fix the root problem of a limited supply of physical space. If
you can't fix available housing inventory, all that happens long term when you
give people more money is that housing just keeps getting more expensive.
We've already seen this first hand with the large salary increases for Silicon
Valley engineers
------
supernova87a
I'm sympathetic to this particular cause but not to the solutions a non-profit
in SF like them would probably propose. (because generally a story like this
is here for the lessons to be taken by others, not for their particular
situation to be solved)
What we need is _less_ picking and choosing who is to receive specific
housing, and setting aside of property or units for them. Because all that
picking and choosing by well-intentioned (but bad overall outcome producing)
people is exactly what's creating the problem.
Everyone who has a special interest in preserving <x> or helping group <y>
puts in their request to their San Francisco supervisor, solving their little
corner of concern but making it worse for everyone else. One by one all the
little barriers (unaware of what the other hands are doing) get erected to
make it impossible to do anything productive for housing.
We need planning at a city strategy level, that admits that San Francisco
cannot stay the way it has for decades, protecting the landlords and people
who've lived there for 30 years from any kind of change. The tax situation is
a given constraint, and we're not going to change that anytime soon barring a
miracle, so the thing that has to be compromised is "neighborhood character"
(whatever that means as a cover for not letting people live near you) or
housing density and your spoiled view of the bay / Muni wires.
Specify what _outcomes_ you want to achieve, and let the rules be updated to
make that happen. Otherwise we will continue to be in a world where the
external factors flooding in (lack of local leadership, jobs creation without
housing creation, corporate money) will be making the decisions for us without
us realizing it -- and a lot of unhappy people who want to live here but
can't, or have been displaced from their housing.
My desired outcomes:
\-- Affordable prices of the general rental and house purchase market (not
"affordable housing")
\-- Owners who actually live in their housing, and are not absentee landlords
\-- Renewal of the creative, productive population and not creating of a rich
/ retired class that occupies all the housing
\-- Good transport and home-work districts, and the attraction of small
businesses
\-- Ability of homeowners (and renters if desired) to easily and cheaply
improve their properties and change the look and feel of their neighborhood
for better/newer
I am _not_ in favor of soft arguments that are disguised attempts to regulate
who is allowed to live in a place according to some particular interest's
judgment:
\-- neighborhood character, density
\-- equity-related arguments
\-- "I got here first"-related arguments
\-- what is "fair"
You will find that if you set up reasonable rules, the communities that emerge
will be just as interesting, good, and pleasant places to live as before. They
may not look the same, and may not be what you thought, and that may make some
people unhappy. But it's what's best for a city.

A video or whatever may be copyrighted, but it's not really possible to
protect a "trick". You can patent a process, but of course this reveals it to
the public.
Most of the described contents of the tracker are commercially released
products. That's really not "stealing tricks" in any way.

Interestingly, this isn't quite true. People are trying to exert copyright
over the specific motions under choreography protection.
~~~
clort
I wonder how this would go down in a court of law, in that the specific
motions they are claiming copyright on were /obfuscated/ or downright
/concealed/ from view. I wonder if you can legally be considered to have
_copied_ something you have not seen..
~~~
regularfry
I suppose what you'd end up copyrighting is the final effect, not how it's
achieved. Which is, I guess, the point.

These aren't exactly big secrets. Anyone can get copies of The Linking Ring,
the magazine of the International Brotherhood of Magicians, and see ads for
many of the tricks that require special props. (There used to be a competing
publication, the "Magic-Gram", but it may be defunct.)
Realistically, if there's a video of a trick, you can usually figure it out.
If there are multiple videos from different angles, it's easier. For that
matter, there are explanatory videos for most of the big tricks on YouTube
now.
I once saw a professional magician having a miserable time performing on the
stage on the Santa Cruz beach. He was doing a levitation, and in brilliant
sunlight it was embarrassingly obvious how it worked.

loup-vaillant
This hints at a more general problem: how does one gather a high-quality
repository of knowledge on any given subject? How do you get enough stuff? How
do you keep the noise down?
I believe some subjects make the problem harder than others. Programming for
instance is full of hard to check claims. Even established techniques are hard
to assess. Say you need to parse stuff. Will you go recursive descent? LALR?
Earley? PEG? Might depend on what you want to parse, which environment you're
working in, how much time you may invest… Or say you write a compiler. Will
you use OCaml/F#/Haskell for the ease of handling recursive data structures?
Or do you want C/C++ because of the speed, and you know tricks to avoid
recursive data structures anyway?
One tempting solution is to start a secret society dedicated to hoard
knowledge on the chosen subject. It would be hard to get in, but once there
you'd only get quality stuff. (Or you might have gotten into a self-delusional
sect…) The idea is, maybe if knowledge was visibly scarce and hard to obtain,
instead of merely buried under a mountain of noise, we would treat it with the
respect it deserves.

Had something like this debate with manager at last job. Came to a head in my
annual review.
Manager: "As senior developer, you lack sufficient knowledge of our most
important application."
Me: "Wait. I am the one who wrote most the documentation that is in our
knowledge base for that application. I am the one who set up the knowledge
base."
Manager: "That is not knowledge. Knowledge is what is in your head."
Me: _blinks incredulously_
I departed the company shortly after this exchange.
But I think you're right. It was certainly the manager's idea that if
knowledge was visibly scarce and hard to obtain, his position would be treated
(and generally was, among his superiors) with the respect he felt it deserved.
But I'd have to assert that this secret society dedicated to hoarding
knowledge was a self-delusional sect.
That's generally been my experience.
~~~
brazzledazzle
That's so bizarre. Was he trying to create some kind of official narrative on
paper that he had the knowledge and you didn't? Or was he trying to tell you
to document less and hide information?

klenwell
> Was he trying to create some kind of official narrative on paper that he had

Yes, this. We had actually worked together amicably for several years, he as
senior, I as mid-level. Then we both got bumped up. As part of my new
responsibilities as senior, I tried to surface issues and confront them
transparently. I was mindful not to point fingers or show anyone up but rather
identify them as shortcomings in our practices or policies.
For cultural reasons, I think he felt threatened by this and assumed it was
his responsibility to hide issues and save his own face. It fell apart pretty
quickly. It sucked but I've used it as a career lesson.

I have been interested in magic for a long time, and have subscriptions or
accounts at most major magic retailers in the world. I am not the best at
performing magic tricks (mainly because I don't have that story telling
personality that is needed to execute most tricks), but I love learning them
and practicing them in my spare time.
No need to go to the dark net though - 99% of magic tricks are now readily
exposed on Youtube public channels, and I am not just talking about the
original instructions videos being leaked on there. A myriad of kids stand
ready to either perform tricks so badly that they give away the techniques, or
else outright show how things are done.
Still though, it is like seeing how a commercial airliner is flown. Watching
hundreds of hours of video footage is no substitute for formal training and
real like practice.
Also, one of the biggest draws of magic to me is hearing of the origins of
most tricks, and researching guys who came up with these things over a hundred
years ago.

I was at a deep learning conference recently. The topic of how AI can improve

in a way that won't be rejected. Another panelist said that he was working
with another startup that wants to use AI and NLP to help insurance companies
reject claims.
I think in the future we'll see their AI fighting against our AI in an arms

Not to be too obtuse, but isn't WordNet (you know, the project that inspired
the creation of ImageNet) "an ImageNet for language"? It seems kind of weird
to bring up ImageNet within the context of NLP and not mention WordNet once.
~~~
sebastianruder
WordNet (as you probably know) is a database that groups English words into a
set of synonyms. If you consider WordNet as a clustering of high-level
classes, then you could argue that ImageNet is the "WordNet for vision",
meaning the clustering of object classes. The article uses a different meaning
of ImageNet, namely ImageNet as pretraining task that can be used to learn
representations that will likely be beneficial for many other tasks in the
problem space. In this sense, you could use WordNet as an "ImageNet for
language" e.g. by learning word representations based on the WordNet
definitions. This is something people have done, but there are a lot more
effective approaches. I hope this helped and was not too convoluted.

TLDR the standard practice of using 'word vectors' (numeric vector
representation of words) may soon be superceded by just using entire
pretrained neural nets as is standard in CV, and we have both conceptual and
empirical reasons to believe language modeling is how it'll happen.

>> In order to predict the most probable next word in a sentence, a model is
required not only to be able to express syntax (the grammatical form of the
predicted word must match its modifier or verb) but also model semantics. Even
more, the most accurate models must incorporate what could be considered world
knowledge or common sense.
So, the first sentence in this passage is a huge assumption. For a model to
predict the next token (word or character) in a string, all it has to do is to
be able to predict the next token in a string. In other words, it needs to
model structure. Modelling semantics is not required.
Indeed, there exist a wide variety of models that can, indeed, predict the
most likely next token in a string. The simplest of those are n-gram models,
that can do this task reasonably well. Maybe what that first sentence above is
trying to say is that to predict the next token with good accuracy, modelling
of semantics is required, but that is still a great, big, huge leap of
reasoning. Again- structure is probably sufficient. A very accurate model
modelling structure, is still only modelling structure.
It's important to consider what we mean when we're talking about modelling
language probaiblistically. When humans generate (or recognise) speech, we
don't do that stochastically, by choosing the most likely utterance from a
distribution. Instead, we -very deterministically- say what we want to say.
Unfortunately, it is impossible to observe "what we want to say" (i.e. our
motivation for emitting an utterance). We are left with observing -and
modelling- only what we actually say. The result is models that can capture
the structure of utterances, but are completely incapable of generating new
language that makes any sense - i.e. gibberish.
It is also worth considering how semantic modelling tasks are evaluated (e.g.
machine translation). Basically, a source string is matched to an arbitrary
target string meant to capture the source string's intended meaning.
"Arbitrary" because there may be an infinite number of strings that carry the
same meaning. So what, exactly, are we measuring when we evaluate a model's
ability to map between to of those infinite strings chosen just because we
like them best?
Language inference and comprehension benchmarks like the ones noted in the
article are particularly egregious in this regard. They are basically
classification tasks, where a mapping must be found between a passage and a
multiple-choice spread of "correct" labels, meant to represent its meaning.
It's very hard to see how a model that does well in this sort of task is
"incorporating world knowledge" let alone "common sense"!
Maybe NLP _will_ have its ImageNet moment- but that will only be in terms of
benchmarks. Don't expect to see machines understanding language and holding
reasonable conversations any time soon.

Bad Character: If Chinese Were Phonetic - bemmu

I've seen this sentiment a lot in Chinese-Americans that are not educated in
linguistics, along with other self-loathing sentiments.
First, literacy isn't completely related to the writing system. Look at
Spanish speaking countries, where the alphabet is more phonetic than the
English alphabet.
Second, Chinese characters that are more complex, i.e. consists of more than
one radical, are usually composed with a semantic component, giving indication
to the character's meaning, and a phonetic component, which gives an
indication to the sound of the character. Although this isn't a rule, it helps
a lot, and it's not like English doesn't have crazy non-phonetic spellings as
well (how tf is "through" supposed to be pronounced for a English learner?)
Last, the Chinese language consists of MANY homophones. This isn't necessarily
a bad thing, and not one out of design, but something that is the result of
being one of the oldest language families in the world. It allows for the
concise expression of many things using only single syllables. You might say,
but what about the crazy amount of ambiguity if the language has a lot of
homophones? Well, ambiguity is a huge problem in all languages and our brains
seem to manage. Now, even though homophones aren't a big problem in spoken
language, because of intonation and prosody giving a clue to how to analyze
sentences, written language is a different story, and it would be very hard to
make an easier system to handle it. For all you engineers, the fact that
Chinese has characters is essentially a performance trade off. More
information density for more ambiguity.
~~~
Banthum
It's actually a myth that most Chinese characters have a semantic component
(indicating meaning).
And the phonetic component often doesn't correspond to anything any modern
person would know.
The problem in both cases is the shift of language through China's long
history, and its divergence from the original design of the written
characters.
The problem with the semantic components is that the meaning is re-used and
stretched over and over. E.g. they used to use a 'foot' radical to represent a
journey towards a destination. Later that shifted to mean "in a straight line,
not veering left or right". Later that took on the meaning of "straight and
narrow" or "straight shooter" or "not-deviant". Then it becomes, "not
deviating from the right path". So now, the old foot radical typically means
"justice" or "correct".
And the image shifts over time. This is the old foot radical now: 正 Does it
look like a foot to you?
The problem is with the phonetics is language shifts. In many cases, in
ancient Chinese, the characters do have a phonetic component that hints at
pronunciation. but, the pronunciation changed over the last 2000-3000 years,
so the pronunciation hint that made perfect sense in the Han dynasty is now
meaningless because you're speaking a different language.
The result is that in the end the characters end up being arbitrary phonetic
symbols with some arbitrary meanings attached.
~~~
truthexposer
You're speaking out of your behind. Of course the signs are arbitrary with
respect to their signifiers, that's any language, but there are still mappings
between signs and their signifiers. English is no difference, am I supposed to
know what a 'm' sounds like by looking at it? Look up the Rebus principle, it
happens in every language.
And with respect to the phonetic shifts, from a linguistic perspective, most
changes of the phonetic radical involve one change of the initial sound, i.e.
bilabial to interdental, dental to alveolar, voiced to unvoiced. With respect
to the phonetic inventory of the language, these shifts are only one feature
shifts within an old SPE framework. These small featural differences, whether
conscious or not, (usually unconscious because we acquire languages during our
infancy) are picked up and used by the speaker of the language to categorize
words.

Color me shocked that somehow the author found the alphabet of his native
language to be superior.
This article takes as a given some assumptions that I don't understand at all.
China being resistant to change? There are few cohesive societies that I can
think of that have experienced more change than China since the end of WWII.
And it would be an understatement to say that the rise of literacy rates are
more strongly correlated with industrialization than adoption of phonetic
alphabets.
I think it's telling that the author grew up in a Chinese-American community.
Expat communities tend to lag their mother cultures in terms of social
progress. An experience growing up in a community could explain this "steeped
in tradition" characteristic that is attributed to Chinese culture here.
Disclaimer: I'm a white American. My wife is Chinese and emigrated herself
from China as a young adult; I get a lot of my perspective from her. Would be

@waqf my point is that being harder to learn the written language does not
mean that the language is _objectively_ inferior as a whole. There is no
universal set of objective metrics to judge the value of a language, and such
an assertion approaches cultural chauvinism.

thedz
For context, to forestall some knee jerk reactions I'm seeing:
1\. This essay is part of a series, where guest authors are explicitly asked
to "uninvent" something. So there's a level of built-in hot take to this.
2\. The author is Ted Chiang, writer of Story of Your Life (and the work that
the movie Arrival was based on). He's explored how language affects how we
think before (Story of Your Life/Arrival is explicitly about this). So this
kind of falls in line with that.
Anyway, I think this is a fascinating thought experiment to work through. What
_would_ China be like with a phonetic system? What would change? How much of
the culture is derived from the method of language and how much from other
factors?

Nadya
_> I would never have to read or hear any more popular misconceptions about
Chinese characters—that they’re like little pictures, that they represent
ideas directly, that the Chinese word for “crisis” is “danger” plus
“opportunity.” That, at least, would be a relief._
But... they are? They're ideograms and there is at least _some_ reasoning to
many of them. Things written with a part of "fire" tend to have a relation
to..well...fire and heat.
火, 烧 炊. You might see the relation 秋 shares with fire. But don't fall into the
trap that it is 100% consistent because you'd be wrong about 約.
And the last statement isn't even (technically) _wrong_. I'm not sure if the
Chinese word is the same [0] but for Japanese it is 危機. With individual
readings of "danger" and "opportunity" although a more reasonable 1-to-1
equation would be "danger" and "occasion". A crisis _is_ a dangerous occasion.
機 happens to have several meanings and one of those is "opportunity". It is
probably intentionally misleading but not incorrect to say it is danger +
occasion.
You can't have your cake and eat it too. For most compound words the
individual meanings of the hanzi/kanji are very relevant - maybe not _always_
relevant but more often than not.
[0] Google Translate tells me it is, so my confidence is >0% but not by much.
~~~
gizmo686
Most of the time (In Japanese, at least), the Kanji do not map to meaning per-
se, but to roots. For example, in English, we have words like "lap-top", "uni-
cycle", "roof-top", "blue-berry", that clearly have multiple semantic
components within them. In these cases, in Japanese, the words would be
written with the kanji for their roots. In more linguistic terms, the kanjis
often refer to morphemes, not ideas.
There are some exceptions. For example, in Japanese, today (kyou) is written
as "今日”, even though it is a single morpheme. In cases such as this the kanji
are used for their meanings. In cases such as this, is is not clear how much
the kanji actually help, because the sementic information provided is precisly
the information that you would get from knowing the roots, and you (or rather
a native speaker) does not have to be taught roots (or at least those roots
that still have semantic meaning).
~~~
Nadya
I'm not sure what you mean by separating "meaning" from "roots". To myself
they are one in the same (the root word or a meaning of the root "word", there
is no difference in my opinion). Could you provide some examples of what you
mean? Maybe I'm thinking too literally or you meant "root" (as in radicals)
different from "root" (as in root word).
「自転車」, 「図書館」, 「作家」, 「日光」,「棋士」. You even have witty ones like 「親子丼」. Just have
to be careful about ones like 「多少」.
The reason I would say not to rely on such literal meanings to define words is
because some require some stretch of the imagination like「子宮」 and my rule of
thumb is if it it requires a stretch of the imagination it's because it
doesn't actually mean that. But literal translations can still be useful as
mnemonics to learn new words/kanji. Like a pair of training wheels that
eventually get removed.

It is the intense educational requirements of the Chinese character system

still end up with a similar block structure, but it is phonetic and has about
the same number of components as there are letters in the English alphabet.

Some linguists (mostly Western) have advocated transitioning to a mixed system
of characters and pinyin. I don't think that will ever happen because an
uglier and less harmonious writing system could not possibly be devised.
Chinese would be much better off with something syllabic and square, like
Hangul. With some amount of fiddling I think it could be made to work for most
of the different Chinese languages and potentially even elucidate cognates
between them, retaining one of the main benefits of characters.

yongjik
FWIW, I like Jared Diamond's thesis better, which is that the geography of
China (a big habitable landmass with no sizable peninsulas or isolated areas)
made a single political entity inevitable. It probably explains why the
Chinese culture has more emphasis on tradition (if that is true, I mean): you
can more easily identify yourself with your ancestors from 500 BC, because
they are all Chinese. A Spaniard would have a harder time identifying with
Celts, Romans, or Moors.

I mostly agree: 500 BC might be a tad too remote in time, but while risking
being pedantic, Spaniards do identify themselves with Moors [1] or Romans [2]

I think in a software startup mindset it could be easy to think that more
efficient => better, but a point not mentioned in the essay is that written
Chinese is simply beautiful compared to e.g., the simple 26 character
alphabet, which is quicker to learn. This also applies to some of the other
alphabets such as Hindi, Arabic, etc. But Chinese has so many characters, it
really shines.
------
wsxcde
As someone who knows a bunch of different scripts (Perso-Arabic/Urdu, Brahmi-
based scripts like Devanagari, Kannada, Tamil, Bengali and obviously the Roman
script), scripts do make a difference.
Yes, a lousy script isn't a fatal impediment. You can produce beautiful
literature even with a poorly-designed script. And I suspect script complexity
is only weakly correlated to literacy. Learning to read involves a lot more
than recognizing characters and words. But a bad script definitely adds a
layer of confusion that is completely unnecessary and ends up creating an
elitist and cumbersome language.
The standard counterpoint to complaints about scripts is some form of
whataboutism involving English. Yes, English is not remotely phonetic, but the
modern form of the Roman script for English is actually pretty decent. It has
a lot of visual differentiation between different letters. Compare this to
Persian and Arabic where the placement of a dot or three makes all the
difference between wildly different sounds.
The Roman script also has relatively few letters. This comes at the cost of
ambiguity, and we need to make up sequences for certain sounds (th, sh, ch),
but also means the learning curve is a lot less steep. Persian and Arabic have
the huge mess involving initial, medial, final and standalone forms of a
letter -- it serves no purpose really. Brahmi-based scripts are all abugidas
which means vowels are folded into adjoining consonants and so you need to
learn about 4X as many symbols as English.
You do have to guess what a letter sounds like in English (g,j,k,c). But this
is also pretty common. Tamil doesn't distinguish between voiced and unvoiced
consonants. This is an unnecessary annoyance. A much worse example is of
Persian, Arabic and Urdu where the script allows one to drop a lot of vowels.
This is especially bad for Urdu. For example, the Hindustani words for here
(idhar) and there (udhar) are written identically in Urdu, so you need to
"backtrack" to fill-in vowels appropriately based on the rest of the sentence.
Yes, English isn't phonetic, and is unstructured and unsystematic. But it is
still a pretty decent script compared to some of the others out there. From an
Indian perspective, I wish we could move to one script -- perhaps some variant
of Devanagari for all our languages. There's really little purpose in
differentiating between Gurmukhi and Devanagari. And we should just forget
about Urdu all together. It made sense when the goal was to teach people one
script that gave them access to both Hindustani and the official court
languages of Persian/Arabic. But for today, Devanagari is vastly superior for
writing any dialect of Hindustani. Similarly, Kannada has an almost bijective
mapping to Devanagari, but each symbol in Kannada is just so much more
elaborate and a pain to write. Life would be much better with one script.
Bring up changing scripts though and people -- and this appears to be a global
phenomenon -- just go nuts! People need to realize that changing scripts isn't
a terrible thing and has occurred many times for many languages. We're not
going to forget our languages/culture just because we choose to change the
symbols we use in writing.
~~~
xenadu02
Perhaps someone with a linguistics background can chime in but my (layperson)
understanding is that many writing systems start out pictographic and evolved
over time, become syllabaries, then eventually alphabets. The Chinese writing
system represents an incomplete transition. Egyptian represents a mixed but
mostly complete transition, as by the late third period their writing system
was mostly based on the sounds of the symbols, not the literal concepts they
originally meant (e.g.: using a snake symbol for the "s" sound). Middle period
writings are often a mix of all three: some symbols used for their literal
meaning, some symbols used to represent syllables, and some for their sound.
Sometimes (but not always) there were markings next to the symbols to indicate
what "mode" you should read them in.
All YMMV of course, I'm not an expert. I try to avoid being too euro-centric
as it is easy for me to claim alphabets are superior because that's what I
know, but it does seem like memorizing abstract rules and a small set of
letters is easier than memorizing thousands of characters. It is certainly
easier to deal with by machine (whether that be a typewriter, a terminal, or
designing a modern OpenType font).

> Perhaps another axiomatic system could compute its value?
Of course another axiomatic system could. If you could tell us such an
axiomatic system for which you can prove that it can determine the value of
BB(7910) and have strong arguments why it is probably consistent (by Gödel one
will not be able to prove this property if it is able to express basic
arithmetic) mathematicians would love to get to know it, since they really
have no idea how such a system might look like.
~~~
ikeboy
It's easy to specify such a system that's more powerful than ZFC and has
strong arguments for its consistency: ZFC+con(ZFC), which is consistent iff
ZFC is consistent.
And it's easy to go one level up, I.e that system plus it's own consistency.
These systems will be stronger than ZFC, and will prove the machine in
question halts.
Of course, the lowest unknowable from ZFC BB number is probably around BB(15),
so likely none of those systems get that high, but they do probably give us
more than just ZFC does.
See also

for some limitations on this.
Also, there are large cardinal axioms which imply the consistency of ZFC and
are believed to be consistent, but I'm not so familiar with them. I think
mathematicians would consider those axioms as "what such a system would look
like".

rrobukef
They created a Turing machine that may run forever. However we can't prove
that. It could stop the next second, or tomorrow, or the day after.
They also proved however that you'll never see it halt. Because that would be
a proof of consistency.
Wait. What?
~~~
zodiac
If you're refering to Yedidia and Aaronson's machine, the machine searches for
counterexamples in ZFC. We believe, but cannot prove, that ZFC is consistent.
Also, we can prove that assuming ZFC is consistent, ZFC cannot prove that ZFC
is consistent. Hence, since we believe ZFC is consistent, we believe that the
machine will not halt, but we can't prove it. This implies that BB(7910)
cannot be computed.
~~~
ikeboy
BB 7910 can be computed: it's just a finite number. What you mean is that the
value can't be proven correct in ZFC.
~~~
zodiac
If you write down a value for BB 7910 but can't prove that it is correct, I
wouldn't say that you "computed it".
~~~
ikeboy
But ZFC isn't the only system in town. It's possible (although highly
unlikely) that we could prove its value in another system that we can see to
be just as valid as ZFC. (Like adding consistency axioms and so on.)
~~~
zodiac
Yeah, sure, if we agree to do math in the system ZFC+Con(ZFC) we can prove
that Yedidia's machine does not halt. But then we can just construct another
machine (call it M', a n'-state turing machine) that searches for
contradictions in ZFC+Con(ZFC), and now we believe that M' does not halt, but
we can't prove it; and now, BB(n') can't be computed.
~~~
ikeboy
Sure, but that n' will be larger.
~~~
zodiac
Sure, but no matter what model of math we choose to work in, I can come up
with some n such that I can say "...hence, BB(n) cannot be computed", and you
cannot reply "BB(n) can be computed; it's just a finite number. What you mean
is the value can't be proven correct..."
~~~
ikeboy
It can always be computed. If you're choosing a specific model of math, you
need to specify that in your statement.
It will still be computable within that model, just not provably so within
that model.
Computable has a very specific meaning in computability theory, and any finite
number is computable.
The _function_ BB(n) is not computable, but this was known for decades, it has
nothing to do with the recent result.

OK, now I'm confused; what is the specific definition of "computable number"
you're using?
Also, informally speaking, say we're both working in ZFC. You claim that
BB(7910) is computable. What does that mean? Does it mean you can write down
its value as a normal decimal number?

>I mean, in my most recent statement I quantified over all consistent
models...
Not quite, as I pointed out in
[https://news.ycombinator.com/item?id=11753020](https://news.ycombinator.com/item?id=11753020).
You can easily have a consistent system that proves the value of all BB
numbers, it just won't be computable.
If you restrict us to computable consistent systems, then for any given model
there will be some value of BB it doesn't prove, but also for any given value
of BB there will be some consistent model that proves it. There's nothing in
particular added about knowability by Aaronson's et al result, only about
provability.
>OK, now I'm confused; what is the specific definition of "computable number"
you're using?
[https://en.wikipedia.org/wiki/Computable_number](https://en.wikipedia.org/wiki/Computable_number)
Any finite number is computable, we just can't prove that a specific machine
_is_ the one that computes BB(N). We can prove that some machine in a finite
set (all TMs of size N we haven't seen to halt or proven nonhalting) computes
it, but we can't pin down which one, within that model.
>Also, informally speaking, say we're both working in ZFC. You claim that
BB(7910) is computable. What does that mean? Does it mean you can write down
its value as a normal decimal number?
Lol nope. We can't even write down anything above BB(6). BB(7) has more digits
than atoms in the observable universe.
My claim that BB(7910) is computable means there's a Turing machine that
computes it. That's easy to prove, as any finite integer can be computed by a
Turing machine.
There's no Turing machine that computes every BB number sequentially, though.

I'm trying to get an intuition about why this whole game can even be played,
and it's proving (ha) rather tricky. I'm ok with the idea that things
sometimes cross into the realm of the impossible when transitioning from
discrete/finite to continuous/infinite, or maybe from countably to uncountably
infinite, but the notion that there's some _constant threshold_ seems so
counterintuitive. The link at the end of the article is pretty good [1] as is
wikipedia [2], but I'm clearly missing some intuition here. Help!

You can't solve the halting problem. Therefore, if you take a program that
takes a Turing machine as input, searches for a proof in ZFC (or your favorite
alternative) that the program halts or that it doesn't, and if it doesn't find
a proof either way then it runs forever, your program is not a halting solver.
Therefore, there are some Turing machines which can't be proven to halt or run
forever in any given consistent system that can be computed.
(Because if every TM had a proof, then the program above would solve the
unsolvable halting problem).
Therefore, there is a smallest such program that's independent of ZFC.
Does that help?
~~~
shmageggy
Yeah a bit. This part
> searches for a proof in ZFC (or your favorite alternative)
is tripping me up though. It's not obvious to me that you can do this in an
automated fashion. I assume this is a standard tool for theorists though? How
does such a program work?

This is my project... not sure why it suddenly appeared on HN today, but happy
to answer any questions.
There is a short talk from Fosdem

One of my main ideas was to make things easier to understand by having
everything in a scripting language; I chose Lua as the LuaJIT ffi had just
come out. At some point porting it to other languages would be a good idea.
~~~
blindgeek
Have you looked at scsh (AKA the Scheme shell)? How does your work compare
with it? It seems like your goals are similar, except that you're working in
Lua.

justincormack
My goal really hasn't been to define something that is convenient to use as a
shell (ie compositional etc), but something for programming, so it returns
data structures which differ by function etc. Plus I provide lower level
functions like namespacing and so on.

Lots of people seem to declare ; or , to be useless keys and remap them.
They're two of my most used movement keys in certain circumstances.
I used to have , remapped to <leader> but switched back when I realised what I
was missing out on. I'd advise anybody else to reconsider if they've made the
same mistake I did.
~~~
danneu
I've had ; mapped to : forever.
Is there a use for `;` I'm missing out on? `;` just seems to be for stuff like
"`fp` -- Oh wait, I didn't see all the p's between my cursor and the p I
wanted. ; ; ; ;."
Now I use easymotion.vim which obviates that scenario.
~~~
goldfeld
I created vim-seek exactly for this reason, it's like f but takes always two
characters, way faster than easymotion within the line (though I still use
easymotion for longer distances) <http://github.com/goldfeld/vim-seek>

Some small vim tweaks I've recently been using myself that I find very nice:
nmap <CR> :write<CR>
cabbrev w nope
Re-map enter to save the file. If you try to do a :w it will yell at you until
you take out the cabbrev so you can retrain your muscle memory. Took me about
a day to retrain.
let g:EasyMotion_leader_key = ';'
nmap s ;w
nmap S ;b
Remap s and S to be easymotion forward and backward. I never use s, since it's
largely a redundant command, and didn't like having to do a two key command
for easymotion. (You can set the leader key to whatever here, the nmap's are
the important part.)
noremap <C-H> <C-W>h
noremap <C-L> <C-W>l
noremap <C-J> <C-W>j
noremap <C-K> <C-W>k
Move between panes with motion keys with control held down.
Also the YouCompleteMe plugin got some HN airtime but it really needs to get
more. It's amazing.
<http://valloric.github.com/YouCompleteMe/>
And as others have mentioned using vim inside of tmux is very nice. It's
especially helpful to remap the entire tmux keymap to be vim-like.
Also, does anyone have any suggestions for what to re-map Space to? I am
amazed Enter and Space in command mode both do relatively useless things.
Remapping space to page down is OK but I use ctrl-f/b which is just as fast
imho.

I'm not sure why the author advocates job control (ie ctrl-z/fg/bg) instead of

drops).

My single greatest tip to make vim even more amazing is to run it in a tmux
session: It makes it super easy to split panes and create new windows for
related things you need to do (git stuff, compilation, running tests, running
a REPL, etc.)
~~~
gnosis
You can easily split panes (called windows in vim) within vim. You can also
create new tabs within vim for related things you need to do.
I still use tmux or screen to do other things which aren't convenient or
elegant to do within vim, but splitting windows and creating tabs can be done
just fine within vim itself (or, in my case, within gvim, which I prefer due
to the increased color gamut and keybinding abilities over terminal vim).
~~~
SeoxyS
When I said split panes in tmux, I meant to put shells, repls, or servers. I
also use split panes and tabs within vim for extra buffers.

The author mentioned CtrlP for fuzzy filename matching. Its great because it's
in pure Vimscript, but in my experience it becomes unusably slow for
moderately sized projects. A month or two ago, I switched back to CommandT
(requires Vim to be compiled with Ruby support, engine written in C) and
haven't thought twice about it since then.
~~~
pieceofpeace
I have a repo with 3000+ files and I can't notice any delay searching with
CtrlP. I have the following custom file listing command in my vimrc:
let g:ctrlp_user_command = {

\ 1: ['.git/', 'cd %s && git ls-files'],
\ 2: ['.hg/', 'hg --cwd %s locate -I .'],

_One of Vim’s strengths is that it starts lightning fast, so starting Vim from
the terminal is trivial. With a modern, 256-color terminal like iTerm2 or
Gnome Terminal, it will even look like gVim. But the best part is that you can
drop into the command line at any time with Ctrl-Z, which suspends Vim, and
your working directory is where you left off._
Is there any reason to do this instead of _!sh_ within Vim to drop into a
shell?
~~~
slurgfest
have your terminal map Ctrl-Z to fg, and you can cycle in and out of the shell
almost instantly from vim with that key.
~~~
bsg75
As in Ctrl-z to background, and Ctrl-Z to fg back into vim from the shell?
~~~
danneu
I'm sure they mean `map fg <c-z>` in Vim so that `fg` from Vim lines up with
`fg` from shell and you can repeat the same stroke to easily "toggle" Vim.

I can live without Vim but cannot without Vim mode.
All apps I have used since learning Vim has some kind of Vim bindings - Visual

Can vim do the following?
I'm editing some project with 10000 C++ files.
There is some C++ file I currently don't have open, say "palette.cpp" which is
in a subdirectory "project/graphics/algorithms/color/".
Now I want to open palette.cpp without ever having to type, not even with tab
autocompletion, that path.
IntelliJ (which I do use for C++ ;)) can do this easily: just press CTRL+R,
then palette.cpp, ENTER, and there you are in that file.
Another thing: Some IDE's and editors have this feature where if you change
lines, it marks it with some color on the left, as well as colors in the
scrollbar, to immediately see which parts of the file were changed compared to
git and/or the last time you opened it. Can Vim do this?
Thanks!
~~~
SeoxyS
The CtrlP plugin will make opening these files a breeze. If you just trigger
it and type palette.cpp, it should be the first match.
~~~
Symmetry
Better, you can type palete.cpp and it should still be the first match.

Every time I read an article like this, it's how a power user installs an
array of plugins and customizations to really soup up Vim, which to me kind of
misses the point. If you want that level whiz-bang, use Coda or Sublime Text 2
or Eclipse or whatever.
I don't recall where I saw this, but someone advised disabling syntax coloring
in your editor to remove a crutch (and, secondarily, to visually simplify your
environment). I've tried this with Vim and it's surprisingly nice [0]. You
have to read the code more closely, and think more carefully about what's on
screen, and this has the effect of focussing me more. Simplifying my
environment, making it more sparse, but always having the power of Vim
available, makes for a really potent, semi-distraction-free environment.
[0] Well, mostly. I leave it on in order to have three colors used: a good
contrast color for code, a second contrast color for strings, and a third,
very low-contrast color for comments and line numbers so that, if I want to
see those things, I can look for/at them, but if I don't, they're easy to
ignore. Likewise, visually distinguishing between strings and code continues
to be really useful.

NAME
ed - text editor
SYNOPSIS
ed [ - ] [ -x ] [ name ]
DESCRIPTION
Ed is the standard text editor.
---
Computer Scientists love ed, not just because it comes first
alphabetically, but because it's the standard. Everyone else loves ed
because it's ED!
"Ed is the standard text editor."
And ed doesn't waste space on my Timex Sinclair. Just look:
-rwxr-xr-x 1 root 24 Oct 29 1929 /bin/ed
-rwxr-xr-t 4 root 1310720 Jan 1 1970 /usr/ucb/vi
-rwxr-xr-x 1 root 5.89824e37 Oct 22 1990 /usr/bin/emacs
Of course, on the system *I* administrate, vi is symlinked to ed.
Emacs has been replaced by a shell script which 1) Generates a syslog
message at level LOG_EMERG; 2) reduces the user's disk quota by 100K;
and 3) RUNS ED!!!!!!
"Ed is the standard text editor."
Let's look at a typical novice's session with the mighty ed:
golem> ed
?
help
?
?
?
quit
?
exit
?
bye
?
hello?
?
eat flaming death
?
^C
?
^C
?
^D
?
---
Note the consistent user interface and error reportage. Ed is
generous enough to flag errors, yet prudent enough not to overwhelm
the novice with verbosity.
"Ed is the standard text editor."
Ed, the greatest WYGIWYG editor of all.
ED IS THE TRUE PATH TO NIRVANA! ED HAS BEEN THE CHOICE OF EDUCATED
AND IGNORANT ALIKE FOR CENTURIES! ED WILL NOT CORRUPT YOUR PRECIOUS
BODILY FLUIDS!! ED IS THE STANDARD TEXT EDITOR! ED MAKES THE SUN
SHINE AND THE BIRDS SING AND THE GRASS GREEN!!
When I use an editor, I don't want eight extra KILOBYTES of worthless
help screens and cursor positioning code! I just want an EDitor!!
Not a "viitor". Not a "emacsitor". Those aren't even WORDS!!!! ED!
ED! ED IS THE STANDARD!!!
TEXT EDITOR.
When IBM, in its ever-present omnipotence, needed to base their
"edlin" on a UNIX standard, did they mimic vi? No. Emacs? Surely
you jest. They chose the most karmic editor of all. The standard.
Ed is for those who can *remember* what they are working on. If you
are an idiot, you should use Emacs. If you are an Emacs, you should
not be vi. If you use ED, you are on THE PATH TO REDEMPTION. THE
SO-CALLED "VISUAL" EDITORS HAVE BEEN PLACED HERE BY ED TO TEMPT THE
FAITHLESS. DO NOT GIVE IN!!! THE MIGHTY ED HAS SPOKEN!!!

Here are my 2 cents
set undofile " This creates a undo file that persists your undo history when
the file gets closed
imap >> <ESC> " Double right arrow to escape from insertion mode. This is
faster and more comfortable (at least for me) than to reach for tab key for
some people
set clipboard=unnamed " This is bridges between your Vim yanks and your system
clipboard
~~~

undofile sounds great! I didn't know about it.
Some people use jj to go to the normal mode. Personally I remapped Caps Lock
to Escape in my whole system, so I can go to normal mode easily.
You can yank to the system clipboard by providing appropriate register to yank
into. You do that by pressing "* before the yank command (e.g. "*yy to yank
the current line).

Minor nitpick, but can any terminals do squiggly underlines or is that still a
gVim only feature?
~~~

Squiggly underlines? What, do you mean:
1 class Hello
~

--INSERT--
Like that? Of course; heck, even xterm does that fine. If you were referring
to something else, I'm not too sure...
EDIT:
Never mind, now I know what you're talking about. No, I don't think you can
get those in terminal vim, but I'm pretty sure there is a plugin for it.

I can recommend CtrlP (or Command-T). I can't imagine navigating in a project

Sometimes you want to indent more than once. This remap is fine, but the

It doesn't hurt to get used to that.

If that's your only reason, stick with emacs but use evil-mode. I flip-flop

I use nvi, and have tried to switch to vim a dozen or so times over the years.
But there are so many irritating little quirks and misfeatures and annoyances
that I can never manage to fix. Does anyone know of a guide to getting a sane,
non-broken vim working with some basic plugins like syntastic? Last time I
tried I couldn't bind F-keys for some reason, I couldn't get syntastic's error
marking column to stay on instead of shifting my text back and forth all the
time, I couldn't get auto-complete mapped to tab properly, and a few other
things I can't remember now. I eventually gave up again as the extra
functionality of vim ends up being counter-productive when none of it works
right.
~~~
slurgfest
It sounds like you want vim features. But vi compatibility mode is probably
not consistent with these. Mapping f-keys should work fine in a GUI vim, but
in a terminal F-keys may depend on configuring the terminal. You don't have to
use syntastic if it doesn't work right for you, you can just use individual
checker plugins or set makeprg and use :make. Mapping auto-complete to tab
depends on not having multiple plugins fighting over the key. Most of this is
a matter of particular plugins, not vim itself.
~~~
papsosouid
Right, I want some of the vim features, mainly plugins. I don't enable vi
compatibility, it isn't even remotely vi compatible and it just breaks stuff.
I want syntastic, that's the primary motivation for trying to get vim working.
I just want it to be helpful instead of irritating. No plugins are messing
with tab, I am just trying to get it to work using a normal mapping.

Backtracking, Interleaving, and Terminating Monad Transformers (2005) [pdf] - setra
http://okmij.org/ftp/papers/LogicT.pdf
======
danidiaz
These notes explain the logic monad by solving solve n-queens with it:
[https://github.com/sshastry/queenslogic](https://github.com/sshastry/queenslogic)
Despite its name, it's more of a search monad, it doesn't perform unification
or anything like that.
Another interesting paper is "Monad transformers for backtracking search"
[https://arxiv.org/abs/1406.2058](https://arxiv.org/abs/1406.2058)
The Select monad described in the later paper can be found in the
"transformers" library
[http://hackage.haskell.org/package/transformers-0.5.4.0/docs...](http://hackage.haskell.org/package/transformers-0.5.4.0/docs/Control-
Monad-Trans-Select.html)

Oh neat, I didn't know Ross had actually released a version of transformers
with Select. Now I've _got_ to go learn it.

misja111
I like FP and Haskell, but when I read a paper like this and realize the
amount of effort it takes to implement a basic backtracking algorithm, then I
wonder if Haskell can ever become mainstream in production environments.
~~~
mbrock
Do you know of an example of another general backtracking DSL implemented in
another language that is significantly easier or more concise?
~~~
misja111
This is not what my comment is about. You wouldn't normally write a general
backtracking DSL in an imperative language because a backtracking algorithm is
trivial to write.
Only when you are using a pure functional language it becomes non trivial to
combine the results of the individual sub branches.
~~~
setra
Perhaps you misunderstand what this is doing? Or perhaps I misunderstand what
you mean.
If all you want is to take some kind of search function or backtracking system
that generates a stream of results then combining the sub branches is trivial.
If you represent a stream as a list and use something like Haskell that is
lazy, then all you have to do is literally combine the streams.
myStreamGenerator1 p1 ++ myStreamGenerator2 p2
if you want a different search strategy you can intersperse.
concat . intersperse (mySG1 p1) (mySG2 p2)
the cases being DFS and BFS
~~~
misja111
With backtracking you typically have some kind of pruning stragegy. That means
keeping track of your best result so far and dont go into branches where it is
clear that they can never beat your current winner anymore.
So you cannot simply concatenate the results of the subbranches, each new
branch needs to be aware of what has been found so far. That can quickly
become ugly in pure FP, that's why people have been looking for solutions that
do that in an elegant way, e.g. using Monads.
~~~
setra
Pruning can be implemented by just not computing a part of a stream based on
some predicate.
If you want some kind of global state of the current results then you just
pass around the current calculated states. Pure FP has many simple solutions
for passing around state.

Machine Learning Fairy Dust - stdbrouw
http://stdout.be/2011/07/18/machine-learning-fairy-dust/
======
law
What makes me really nervous is that we're nearing the point when Google's
Prediction API and its knock-offs will increasingly pervade web sites much in
the way that AJAX and other technologies have. While overuse of AJAX and the
Facebook "Like" button is extremely annoying, it's still pretty harmless.
Machine learning, on the other hand, isn't innocuous. In order to use the
Prediction API, you need a large corpus of data, which will just further
incentivize web sites to ignore the privacy implications of their actions.
Machine learning is far too abstract and too much of an "umbrella" term for it
to be anything but careless to refer to it as some sort of panacea.
If you thought that Facebook's "Beacon" was a slap in the face to online
privacy, just wait until you see what the feature holds. Once machine learning
libraries with extremely robust, completely unsupervised classifiers become
more abundant, we're going to see an exponential increase in the market for
data. Banner advertisements will be replaced with much more terrifying
'targeted' ads, and we will enter into an age where we are judged not by the
empirical evidence of our actions, but the inferences made from people who
behave like us.
~~~
bluekeybox
> Banner advertisements will be replaced with much more terrifying 'targeted'
> ads
Can someone please explain to me why ads for stuff I might actually be willing
to buy (as opposed to hyper-annoying junk thrown at me every day) terrify so
many people?
Not that I am ambivalent to privacy issues; just playing devil's advocate
here.
~~~
makmanalp
First, everyone assumed that no one knew knew about anything they did on the
net. They thought that when they looked at an oven mitt in an online store,
only they knew about it. The truth was that information was just unused by the
store, and so the user never saw it.
Gradually, this notion became slowly dispelled when stores actually started
leveraging this information to provide, for example, suggestions. It's all
fine and good here.
Finally came targeted ads. The part that people find terrifying is when the
suggestions are "following them around!". This is creepy in multiple aspects:
The first is that people don't quite understand _how_ this happens (of course,
_we_ do). How is this information showing up in different websites? Did the
store just let these other sites handle my information? In their eyes, the
boundaries for who is allowed to my personal information seem to blur. This
also breaks the paradigm of location that the user has in their mind. "If I
don't go to site X that is, I won't see anything about site X." It looks like
everyone knows everything.
The second is that it's creepy-through-analogy. The fact that it's going
wherever you're going and nagging you constantly is weird. When I walk into a
retail store, I'm usually asked if I want any help, and I decline politely.
If, however, the salesperson keeps approaching me and trying to sell me things
that I don't want, I get the fuck out. With targeted ads, the average user
can't do that! The creepy sales guy is following you out to the street and
into your home. This usually ends in extreme frustration.
Finally, there are also some nuances that targeted ads miss. Targeted adds are
actually not that targeted, they're just there to grab at the "low hanging
fruit" customers that are on the verge of making a decision. Just because I
looked at a dildo once because I thought it was funny doesn't mean I want to
be bombarded with the world's finest penis emulators for the next 3 days.
~~~
lotu
So use, ad block and/or incognito mode. Problem solved. And don't say that
most people don't know how to use these features. While true anyone, who is
concerned about this is totally free to ask other people or even pay them to
explain and solve the problem for them. The fact that they don't suggests to
me that they _don't care_. Most of the whining about privacy is more the
poster being upset that not enough other people are concerned in the same way
the poster is.
~~~
makmanalp
I'd like to point out that I came by the above insights after a conversation
with my aunt (who is in her 40s), accompanied by a few other older relatives.
I do actually care but those statements were not a reflection of _my_ cares,
it was of theirs. While this is not equivalent to a comprehensive study of
average computer using people across the world, they sure as heck cared but
didn't even begin to know where to start, in contrast to what you are hoping
will happen.

hammock
There are NO shortcuts. This is a fantastic article, and he lists a lot of
good examples- machine learning, "social", crowdsourcing, AJAX, real-time.
I would add to that list "create a forum." Maybe that's part of "social." In
marketing I hear it all the freaking time- you get a half-ass mediocre idea
and it always includes some type of "forum" your customers will recruit
themselves into somehow, and start to form a community. Most of these people
have never been on a forum so I can't blame them for not knowing how it works,
but it is a challenge.

I think his point is that it's just a tool that makes it a little easier for
startups to incorporate machine learning into their products - like he said,
it may be appropriate for some types of problems, but not all. But I'm sure
we'll start to see more tools like that become more widely used.
When AJAX first came out, not everyone knew how to do it - but now, everyone
can drop in jQuery and do all sorts of complex things relatively easily.
~~~
dholowiski
I guess that a good point. I wonder what kinds of bad implementations of the

wccrawford
I think 'machine learning' is so complex that people just don't feel like
trying to explain it. That, or their business secrets are tied up in it, and
they don't want to give away the golden goose.
~~~
_delirium
That's an explanation for some of the examples, but I think a lot of the times
it's actually really simple, along the lines of, "we sift through some data
and correlate it". The odd thing is, that often works, especially for user-
facing perceptual stuff where there's a strong placebo effect, even more
especially if you salt liberally with some hand-tuned biasing. Sort of how The
Sims is able to use some super-simple algorithms to give the impression of
interesting characters.
However, if you _do_ need some real magic to be done, and your product really
won't work without it, then things get trickier; bad statistics, or at least
statistics not really used correctly, is really common in the innards of these
kinds of products.
------
j_baker
I think this is usually a case of marketing having a bit too much say in
product discussions. In the publishing industry, it seems like "My widget does
X" doesn't get as strong a reaction from publishers as "My widget does X _and_
it adapts to your readers".
The problem being (of course) that people forget how hard a problem machine
learning can be.
------
the_cat_kittles
Its fine if people want to say that ML will take care of the "details" ...let
them try to use ML right and they will see you need to spend a long time
understanding how to do things right. Most of the time, you can't use linear
regressions right out of the box, let alone SVM's.
~~~
arasraj
Agreed. The use of ML is highly dependent on the data. Having a something like
the Prediction api is fine, but seems like the use-cases would be rigid.
~~~
taliesinb
Yup, and if commit to it and suddenly realize you need a little more
flexibility than the API provides, you're probably in a worse position than if
you rolled it yourself.
Real-world ML is so full of black magic and hackery that it's the LAST thing

======
jsrfded
Bite your tongue. Folks with far less to show are regularly promoted to
sainthood here.
Marc climbed up from grad student to monster IPO, rode out huge corporate
stuff at Netscape/AOL, left and started another company, raised huge money,
built a huge business during the dot-com winter, and piloted the ship home
through a dizzy chain of IPO/merger/acquisition. He is now blogging the best
stuff about entrepreneuring you can read anywhere on the net right now.
You should listen to this guy...

cglee
You have to also realize nowadays he's a VC and runs Ning. I believe, like
Mark Cuban's blog, his first interest isn't to disseminate insights, but to
server his business interests.
~~~
neilc
Is Marc A. actually a VC? I think he's been an angel investor in a few
startups, but that's not equivalent to being a VC.
------
iamelgringo
I have to say that I agree with Marc.
The problem with the first bubble wasn't caused by non-profitable companies.
It was caused by hubris over stock prices. The reason why so many people lost
their shirts in the first bubble was because millions of Joe Averages took out
cash advances or cashed out home equity to buy Internet stocks. There was a
lot of hubris around the NASDAQ and average investors jumped in on the action
en masse. I personally knew at least 4-5 people who had left their jobs to
become day-traders.
I worked with a Med student who had maxed out 8-10 credit cards, bought high
tech stocks with them, and then bought a collection of motorcycles with his
stock earnings. When the bubble popped, he was left with a bunch of loans on
expensive motorcycles, $100,000 in credit card debt and a great position on
worthless Pets.com stock.
Sarb-Ox has really clamped down on the number of IPO's that are occuring now.
So, even though there might be hubris around web apps right now, the average
investor has no way of pumping money into those businesses, and that's a good
thing.
What start-ups are creating are several products in tandem: The first is
software that actually does stuff. The second is a community of users that
develop and grow around that software product. The third is a small tight-knit
group of people who have proven their capacity to produce.
Big Co is interested in all three of those things. And Big Co has proven
repeatedly that they are willing to shell out a bunch of cash to aquire the
software, the community or the people. Even if the startup isn't profitable,
the software, community and people are still very valuable to companies that
need those things.
What start-ups aren't creating this time around is IPO fever where the stock
price gets ramped up while the founders and employees cash out. This is what's
going to prevent the next big bubble from forming around web apps for quite a
while this time around. The fundamentals are much better this time around.
~~~
david927
And I have to say that I disagree.
The Web 1.0 bubble wasn't based on the way in which people found the money to
buy these stocks or the hubris in the expectation that these stocks would
always go up. It's just about fundamentals. When you buy a stock, you are
buying how much the company earns today and adjust that for how much it could
earn, say, ten years from now.
People bought Pets.com either with the naive expectation that it would earn
billions in the future or with the expectation other people would think so.
There was no evidence, just lots of hope and the eternal wish to get rich.
So you and Marc are telling me that Facebook is really worth $10 billion. You
two are saying that that's a realistic expectation based on an objective
evaluation and anyone who doesn't agree should be ridiculed. Ah... there's the
hint. Ridicule is a cover for fear. Personally, I don't need to hide. I have
the fundamentals -- and time -- on my side.
~~~
Goladus
I think iamelgringo's point is that it doesn't matter if Facebook is really
worth $10 billion or not, because no one's actually paying that much; and the
entities paying some percentage of those valuations are insulated from the
effects of a crash.
The term "bubble" scares people because of events such as those that happened
in 2000-2001. It's an imprecise term because of that. If you mean "inflated
valuations" we might be in a bubble, if you mean "reckless speculation by
average consumers" then we're probably not.
If Facebook turns out to be a dud before they ever have an IPO, who are the
big losers? A few hundred employees, and some professional investors.
Microsoft is still plenty profitable without Facebook, and VCs will bounce
back or be replaced. It'll indirectly affect many others, but the typical
portfolio of a typical working American will remain relatively stable.
Conversely, if 500,000 average consumers average $20,000 invested in Facebook
and it suddenly goes bankrupt, that's a huge problem. It causes a massive
disruption in their lives, and it will have a much more noticeable indirect
effect on everyone else. (eg nobody can afford to buy Christmas presents this
year)
~~~
iamelgringo
I concur.
It's a free market, and Facebook's valuation is whatever someone is willing to
pay for a piece of Facebook. If Big Co purchases a piece of Facebook for $500
million, then someone at Big Co made a guess that either the software, the
community or the people were worth that much.
Mind you, _I_ don't think that Facebook has a 10 billion dollar valuation, but
that's a moot point, I don't have the $500 million to purchase those shares.
My hunch on the Facebook deal, though is that Microsoft is trying to beat
Google to the punch and wants to provide search services to Facebook. The
software, community or people might not be worth that much to them, but I'm
sure that keeping Google out of Facebook probably is worth $500 million to
them.
What's the worst case scenario for Microsoft? Google doesn't get Facebook's
search, Facebook goes _poof_ in a couple of years and Microsoft is out $500
million. No big deal. Microsoft's cash reserves are well over $25 billion
anyway. They have to spend it on something. Might as well spite Google with
it.

I agree. I felt this was one of the weaker posts on a great blog.
The problem with sarcasm is that it allows the writer to frame the opposition
in exaggerated, silly terms. For instance, the post derides people who claim
VC's are "All stupid, and unnecessary to boot".
Nobody would half a brain would make that claim. Of course capital will still
matter, in many cases. But there is still an interesting emerging argument
that the cost of server space and programming tools have dropped to the point
where bootstrapping has become a real option.
I'd love to see a writer as good and experienced as Marc give me his take on
this new trend. Is it a good idea? A bad idea? When would you want to do one
rather than the other? This is all lost in the sarcasm format.
But I agree with the other posters here who have pointed out that Marc is just
having a little fun taking the piss out of the naysayers. Nothing really wrong
with that. I enjoyed the post, but I hope he gets back to his more insightful
style in his next post.

Ask HN: Should I Remove an Online Pseudonym? - valkorhe
I've gone by a pseudonym online for around 8 years, but now that I'm older (over 18) I've considered replacing it with my actual name so online work I do can be easily attributed to me. This includes social media, GitHub, forums, and normal conversation. This is not a nickname, per se, but rather an actual name different from my own (like John Doe).<p>My primary consideration is GitHub - I would like to have projects I create hosted by my real account used in these online communities. Any form of migration I do would involve changing package name (com.mypsuedonym -> com.myactualname), so there is also a bit of a development aspect to this.<p>Has anyone gone through something like this before, or is able to offer resources on the process? Is this something that is a good idea, or should I prefer to keep using the pseudonym for as long as I'm involved in things online? My opinion is that if a change is to be made the sooner the better.<p>Thanks!<p>Note: I don't have anything online that's sketchy, illegal, inappropriate, or anything to hide from a potential employer or grandmother.

It's a low-budget device (1/6th the cost of an Echo) that uses both automation

shopping research.
But unlike Magic+, there are no fees associated with using the service, apart
from the cost of the device.

======
TomOfTTB
The irony is a lot of the points he makes are reasons to stay out of Silicon
Valley. For example, he cites the "death" of VC money and how it's cheaper
than ever to start a company. But proximity to VCs was one of the big reasons
to move your company to the Valley and starting a company isn't that cheap if
you're paying high rent for both home and office space.
Other than that the other points seem pretty superficial ("it's not cool to
work for a big company", "SV entrepreneurs are getting really good").
~~~
byoung2
I believe he said _dearth of VC money_ and that it's not as big a problem as
the media makes it out to be because it's much cheaper to start a company
these days. High rent isn't a big problem either, because startups can work
out of a tiny shared apartment and use cloud infrastructure and broadband
instead of leasing expensive office space with a T1 and a server room.
~~~
jmtulloss
Those costs that you do have, however, are almost certainly higher in the bay
area.
~~~
byoung2
That is definitely true, but it can be worth it to be near VC and a large pool
of talented people. I could start a company in Phoenix, AZ for pennies on the
dollar vs Silicon Valley, but there would be virtually no VC and far fewer
programmers (sorry Phoenix!).

I really wish there were fewer, smarmy, uninformed, superficial blog posts

post. Just to pick on one point (no. 2):
"People have figured out SOX just means companies should go the acquisition
route. SV has adjusted to the idea of never IPOing"
As an alternative, I'd suggest that in fact the IPO window is suddenly there,
which lifts all boats, including the acquisition boat. Thank you, OPEN.

Show HN: Roq – C++ HFT on Crypto Exchanges with μs Latency - thraneh
https://roq-trading.com/docs/blogs/showhn/index.html
======
thraneh
It's a framework supporting the whole life-cycle:
* Data capture (binary format, streaming, consistent)
* Exploratory research (InfluxDB into Jupyter)
* Back-testing (incl. order matching, very fast!)
* Live trading (suitable for HFT)
This framework has been designed for _professional traders_ who emphasize full
control, ultra low latency and a consistent back-testing framework.
Everything has been designed so you can own, control and deploy your own
software stack.
Our primary focus is predictable ultra low latency during live trading.
We support Coinbase Pro and Deribit and we will soon add more exchanges.
The framework is not limited to cryptos: all interfaces are generic and have
previously been tested against non-crypto exchanges.
We will always use the better (faster, more reliable, etc.) protocol offered
by each exchange: that means FIX being strongly preferred to WebSocket. (REST
is a non-starter for any kind of HFT).
Gateways are _free to use_ during our "beta" testing: we will implement a
license model early 2020 (allowing also private individuals to participate).
_Everything else will remain free!_
Many more details in the linked document. In particular, the minimalistic
"tutorial" towards the end, for those of you who want to try it out.
I'm happy to answer any questions you may have.

Is there a special designer school you go to, to learn how to draw those
colorful, generic human figures (behind the search)? Reminds me a bit of the

The Modern Triumph of the Periodic Table of Elements - Hooke
https://www.bloomberg.com/news/features/2019-08-28/the-modern-triumph-of-the-periodic-table-of-elements
======
sdrothrock
I was disappointed by this article because it has almost nothing to do with
the "Periodic Table of Elements," just the elements themselves -- as if we're
supposed to be surprised by the fact that elements are in things.
The article also presents the number of elements in things as if that can show
some kind of quantifiable change in a positive or negative way (for example,
they call out the number of elements in a cell phone as having increased since
the first cell phone).
I was hoping for something a bit more insightful about the design of the
periodic table itself, whether about
1\. Increasing order by atomic mass (and the ramifications thereof)
2\. Arrangement of periods and the predictions we've been able to make/use
3\. The groups of the table and the predictions we've been able to make/use,
though I guess this is most common among the noble gases
4\. Rare earth metals
And I'm sure there's a lot more I don't know -- every time I learn something
about the periodic table, the more impressed I am by how orderly and patterned
it is today despite having been initially designed (with gaps!) a century and
a half ago.
The article could even have gone into how there are spoofs of the periodic
table just because it's such a lasting, easily-understandable design.
~~~
lonelappde
I'd expect the gaps, because the gaps are a natural consequence of the
structure being interesting - that clear patterns appear as soon as you
assemble a bit of data.
Most spoofs of the PT are bad because they don't have any periodicity, wholly
missing the point.
I suspect this happens because the PT is the most famous organized list in
science, and it's structure (not a simple array!) is fascinating even to
people who don't bother to understand what the structure means (logically, not
to mention chemically).
If you are really into the "Periodic" and "Table" aspects, check out Theo
Gray's Periodic Periodic Table Table posts ;-)

Ask HN: When is risk worth it? - beswift
Alright, so I'm in no way a talented coder or even very technically savvy (much more of an admiring "coder wannabe" actually) but ever since I first stumbled on a PG essay on philosophy (in the midst of a typical googling/reading binge) a year or so ago I've become a daily troller of the HN site. During this time, I've become an avid reader of numerous tech blogs and have a huge appreciation for the way you guys process ideas and your thought processes in general. That being said, I would very much value some opinions on a (happy) career crossroads I've found myself in.<p>The short on me: I'm a 27 year old, hard working clincal coordinator for a mid-sized private medical practice (by hard working I mean hours don't phase me, I work for the clinic during the day, and split my nights and weekends between a free clinic and waiting tables.. student loans rock!). A 70-80 hour work week is pretty much a standard, and I'm fine with that.<p>My dilemma: My current job at the clinic is great, I initially took the job to help out my dad, who runs the practice and was short staffed..and ended up loving it. I've worked my way up from a tech, managing 2 clinical trials, to now running 2 of our satellite offices and being in charge of all of the IT stuff (part of my obsession with HN!) I love the doctors and patients I get to work with, and have been experiencing a steady rate of growth, both in pay and responsibility within the practice over the last 3 years (They even put up with and give me free range with our old servers for testing out ideas I have with record sharing.. it's great!)
At the beginning of this year, I got fed up with the horribly arcane way we were tracking inventory and monitoring expensive drug ordering/usage across our 6 offices (literally, sticky notes and texts passed here and there)and decided to write a little program that would allow us to keep track of drug usage/inventory levels and reimbursment periods across all the offices in real time. It ended up working pretty well, and one of our docs ended up showing it off to a drug rep we worked with, who then borrowed it to use as an example for other practices(yay!)
Now I've had a few offers from other practices and an EMR company, but haven't been tempted away.. until now. I was contacted earlier this week by a practice in the city I grew up in (and have been wanting to move back to) and asked if I was interested in taking the administrator position with their practice. They are wanting to implement an EMR, update 5 out of 6 of their offices (two do not have internet!), reorganize their practice structure and create/implement a marketing plan. Immediately my brain was spinning, by the end of the week I had talked to each of the partners individually, written out a few plans and was pretty excited about the opportunity. They gave me an offer Saturday, saying they'd rather fly me out once to look for an apartment and get to work than twice to meet me first because they knew they wanted me.<p>The catch: Before recieving an offer, I met with my dad, who has been doing this for the past 30 years, as well the main Doctor I work with. Both agreed it would be a great opportunity for me, and said I should jump on it.. on one condition.. they offer $X (the min salary for someone in that position, also the bottom of the salary range that my dad had actually given this practice a year ago when he had done some consulting for them and they were looking to fill this same position) I felt this number was a little high for my experience, however given the amount of work involved an the significant increase in cost of living, it's actually pretty reasonable. Their argument is that the dollar amount shows they are serious about the relationship, and that they would be supportive in future efforts when it comes to updating their systems.
They offered significantly less, actually almost less than what I currently make at both jobs (total hours worked would probably be about the same) I was disapointed, but declined the offer, heeding my dad's advice. They called back today with a slightly higher offer plus an incentive once their EMR is implemented, the total is still less than the original target, but enough that I will make a little more than what I make now..although most likely be working much harder.
They seem like good guys, they've promised that the compensation will increase and surpass my goals once I've proved myself and as my skills mature. The opportunity alone excites me due to the sheer challenge of pulling it all off and the experience I would gain along the way, however it's still definitely a risk, the practice is challenged and I could always fail badly. Additionally, my dad and the owner of the current pracice I'm with have advised that since they failed to offer an acceptable amount from the beggining, I need to move on, arguing their offer shows they aren't serious about changing the organization and I would end up frustrated and set up to fail.<p><pre><code> I would like to know, in evaluating your own job prospects, what makes the risk of a new opportunity worth leaving a safe and stable one? Currently I'm very happy where I am, and am able to "incubate" and grow my skills safely, to the point where in a year or so, the target salary given to this company should be quite easy to obtain. This new job though, while a huge risk, could be a sweet experience that lets me test what I can really do..or can't do, which could undue the gains I've made over the past few years?? I'm extremely conflicted, tired from all the negotiating (so please exucse the grammatical inadequecies!) and this forum has proven to be source of level headed discussion on a variety of topics, so I would greatly value any input/or stories from people with similar experiences.
Thanks for taking the time to read/respond!</code></pre>

_They seem like good guys, they've promised that the compensation will
increase and surpass my goals once I've proved myself and as my skills
mature._
Yeah right. What that means is that they'll throw you a bone after they've
eaten the steak, if everything works out, or put all the blame on you if it
doesn't. Trust your Dad, who has already had experience with the other
practice and has decades of industry experience on you. I have heard these
kinds of promises on many occasions and they almost always fall through.
The fact that they are inviting you to both reorganize their administrative
structure _and_ put together a marketing plan is a big red flag for me. Those
jobs are poles apart, and the problem with marketing is it's very hit-and-
miss. Healthcare is not a normal market anyway, and if they don't know how to
market their own practice something is wrong.
In this case, a bird in the hand is definitely worth 2 in the bush. Besides,
nothing makes you as desirable as your ability to reject people. Be nice about
it, but firm - say you can't afford it and if they wheedle just stick to that
basic point. They will try to wheedle you because they'll figure you're
sufficiently financially secure to risk failure, but basically they're trying
to offload the risk onto you and your Dad. That's just how business is,
they're probably not even fully conscious of it.

Graphic Designers are Ruining the Web - jaems33

======
halefx
I've worked with so many graphic designers claiming to be web designers who
didn't know the first thing about good web design. IMHO, you can't call
yourself a web designer unless you write your own CSS, and graphic designers
should NEVER have the final say in web design.
------
soonisnow
It's about the how, not the who.
Methods evolve, and truly good design is as much about resource efficiency and
user experience as it is interaction dynamics and look and feel.
Today, if our most iconic, beautiful buildings required, like the pyramids,
25,000 laborers hand-stacking mud-brick over a 20-year period, that would be
bad design. If our intra-city train systems ran above-ground, powered by
steam, that would be bad design.
It's not Graphic Designers who are ruining anything, just as it's not Teachers
who are ruining public education. It's bad Designers using inefficient
methods.

A good designer knows how to focus on the most important parts of the content,
and together with a good frontend developer, can take care of making a web
page both beautiful, useful and fast to load cross-browser and device.
Unfortunately many designers tend to be handcuffed by marketeers and CEO's
believing in cramming in as much ads, social media sharing buttons and other
crap as possible 'above the fold'.
That's not a problem of design, but a problem of vision.
------
appleflaxen
This is a fantastic premise, and wildly fun to think about, but I think the
author fails to prove his case.
Good designers eliminate cruft, and if one is conscious of the design, then
it's bad design (although it's possible I'm guilty of applying the "one true

Sugar industry withheld possible evidence of cancer link 50 years ago - mtberatwork

======
qwerty456127
The whole phenomenon of sugar and fructose being added to virtually everything
is beyond comprehension. There are so many people, fat and slim, saying they
don't want to be fat, yet eating foods with added sugar every day. Why not
just replace all the added sugar with erythritol, for example? The whole
situation with sugar reminds me of the situation with opium in early 19th
century China
~~~
ams6110
The reason is that in the 1970s and 80s people started freaking out about fat.
Everyone from the FDA to USDA to family doctor was telling people fat was bad.
So food producers started making fat-free versions of everything. Only problem
is it tasted like shit. So what did they do? They added sugar. So now you have
sugar added to everything from salad dressing to pasta sauce to bread and
muffins. The latter probably had some all along but the fat free varieties had
a lot more.
Edit: I'll add that saturated fat was considered especially evil, which begat
trans-fats substituted everywhere. Turned out they were even worse.
Bottom line, eat minimally processed meats and plants and you can stop
worrying about it.
~~~
gregcrv
There was no fat to remove from pasta sauce. Maybe they also figured out that
sugar was addictive and added it everywhere to sell even more food with sugar?
~~~
tigershark
You need to add sugar to contrast tomato acidity, it has nothing to do with
sugar addiction. And it has been like this since forever, not only from the
'70s. Source: even my grandmother added a pinch of sugar when cooking pasta
sauce.
~~~
AmVess
A very little bit of sugar that's in a pinch isn't any kind of a problem. Even
a tbsp isn't that much. The problem is the massive amount they put in drinks
of all types...and foods of all types. They even put it in bread for heck's
sakes.
In terms of taking the edge off of tomato sauce, shredded carrots works pretty
well. I don't use sugar in any of my cooking, and no one has noticed.
~~~
crx087
Sugar in bread is _so_ nasty to me. I can't stand to eat it, yet it's in
almost every loaf on the shelf at a supermarket with 50 types.
~~~
zaarn
Even without sugar, bread contains a lot of carbohydrates that break down
right into sugar just by coming into contact with the spit in your mouth.
If you think that's not true, simply take a sugar-low bread (check the food
label, don't just go for organic/whole-grain, those usually have more sugar)
and taste it for a while in your mouth. You'll notice it starts to become
sweeter in your mouth.
~~~
KozmoNau7
And that's actually not an issue. As you probably know, glucose is the fuel
our bodies and brains run on, and while your body _can_ break down proteins to
glucose in a pinch, it's not actually healthy (despite what proponents of
ketosis diets will tell you). It's especially hard on the kidneys.
As long as you stick to proper bread without the crazy added sugar, and
preferably whole grain (actual whole grain, not just marketing "whole grain"),
it's not an issue. Unless you try to subsist on literally _only_ bread, of
course.
~~~
zaarn
I'm not talking about various proteins and rather about starch, which is a
natural part of a good bread. The enzymes in your mouth and digestive system
will break down starch to normal Glucose without a problem.
~~~
KozmoNau7
My point is that we need carbs, it is unhealthy to subsist on protein alone.
~~~
zaarn
Obviously, yes. A balanced diet is always a better choice than any extreme
diet. Like basically anything else too.

Sugar is not far from being a drug in my opinion. It certainly feels addictive
and has a definite impact on physical and mental state (especially true with
respect to children). In that sense, it should undergo the same level of
regulation...
~~~
afterburner
I'm all for eating way less sugar, but you might as well say people are
addicted to food. The body needs energy, of course providing it with energy
alters its physical and mental state.
~~~
jmurinello
Totally agree that in current times food is an addiction. Since when do we
need to eat 3 meals a day? At least 90 percent of modern humans history, we
used hunting and gathering to survive. Only in the last 10 percent we have
agriculture, and much much later, refrigerators, supermarkets and convenience
stores. If we needed this much food our species wouldn't last a week before
agriculture. Spoiler alert: we lasted 300,000 years.
~~~
foobarge
Agreed - and it's been proven (citation needed) that a low calorie diet
prolonges life.
But here we are, needing to consume more energy because we do things (good,
bad, useless or wasteful) with our time (and these things aren't _directly_
looking for food.)
------
sillysaurus3
I recently started the Whole 30 diet (paleo), and it's nearly impossible to
avoid sugar, corn starch, and dextrose. Almost all fooeds seem to have one of
those. Often for no reason: why put sugar in beans and bacon, or corn starch
in turkey?
The amount of money I'm spending on food jumped by 3x. It seems accurate to
say that if you're poor, you're almost forced to eat sugar for economic
reasons.
~~~
obstacle1
>Almost all fooeds seem to have one of those
Almost all _prepared, packaged, or preserved_ foods have one of those.
The solution is actually pretty simple: eat meals made from base/raw
ingredients only.
Beans, nuts, meats, vegetables, fruits, vegetable oils, spices... Endless
varieties of stuff to cook with, combine, and eat alone. People just aren't
used to eating this way, because prepackaged crap has been the norm for so
long.
You are right that if you're poor, it's difficult to eat this way, though.
~~~
hydrox24
> prepackaged crap has been the norm for so long
> if you're poor, it's difficult to eat this way, though.
And it is difficult for some poor people to eat this way because their
cultural poverty exacerbates or even causes their financial poverty. Their
parents (if they were lucky enough to have two) didn't teach them to prepare
basic meals, sharpen a knife, or care for a frying pan. Each of these skills
is a barrier to entry, and they add up quickly for basic meals.
It's not the only major barrier, but I think that we have really pulled the
rug out from the poorest by exchanging cultural norms for convenience and a
net rise in costs.

against the mass acceptance, just as there are today for social media.)

Happy Jax => Sugar Crisp => Super Sugar Crisp => Super Golden Crisp => Golden
Crisp
But it's still "Sugar Crisp" in Canada, where Sugar Bear still says "Can't get
enough of that Sugar Crisp"! Do they have better truth in advertising laws
there or something?
[https://en.wikipedia.org/wiki/Golden_Crisp](https://en.wikipedia.org/wiki/Golden_Crisp)
At the 1904 World Fair, the Quaker Oats Company made a candy-coated puffed
cereal, a wheat-based product similar to Cracker Jack's candy-coated popcorn.
The product concept was re-introduced unsuccessfully in 1939 by another
business as Ranger Joe, the first pre-sweetened, candy-coated breakfast
cereal. Post Foods introduced their own version in 1948. The Post version was
originally called Happy Jax, and was renamed to Sugar Crisp the next year. The
name was later changed to Super Sugar Crisp, and in 1985, it was changed again
to Super Golden Crisp. Finally, it was changed to Golden Crisp (during a time
when many cereals dropped the word "Sugar" from their titles) in the American
market.
In the early 1970s, there was a short-lived variation on the original Sugar
Crisp, called Super Orange Crisp, which had orange-flavored O's in it.
The product is still sold as Sugar Crisp in Canada. In Canada, the box still
displays the Sugar Bear mascot and the phrase "Can't get enough of that Sugar
Crisp."

Being overweight is a much stronger correlate to cancer and heart disease than
"sugar".
And, despite what you might have read in the press, it's nowhere near a
consensus that sugar is the primary cause of being overweight. You really
think a 50-year-old study is the smoking gun that's going to usher in a
consensus among nutrition scientists everywhere?
Personally, I buy Stephen Guyenet's theory that palatability is the driver of
overweight. I think it's increasing palatability and falling food costs.

I consider sugar to be no different from cocaine (not that I ever tried), but
we crave for it the same way people who consume that drug or any other, crave
for. Sugar is everywhere, and it's our main source of energy, being that our
body feels terrible when its levels are low, but as soon as you eat it feels
wonderful. The same goes with cocaine.
~~~
anigbrowl
It's a bit similar but I don't think it's good to make second-hand
comparisons. Cravings are not a simple binary. Like, if you consume cocaine
for pleasure then you can have a craving to keep doing more until you run out
or its time to go home or whatever. But below a certain threshold the craving
isn't that strong, so you could have a little bit and then get on with your
day, much as you might have a cup of coffee in the morning but you don't
necessarily want it round the clock.
~~~

I agree, although when it comes to sugar we way past that threshold, since
most of us crave for food many times a day when glucose levels drops.

Has it actually been proven that natural fats are bad for you? I always
thought fat is healthier than sugar. Both sugar and fat are required part of
healthy diet but I’d rather eat some pork sausage than ice cream or chocolate.
It seems much healthier to me but I could be totally wrong and this is just
some irrational belief I hold.

Watch out for that sausage, it's very likely to have nitrite salts in it, as
well as surprisingly high amounts of sodium and sugar.

richardknop
Is salt unhealthy? I thought that is a myth too. I think salt is required part
of healthy diet. In moderation of course.
Sugar? Hmm I didn’t know there’s much sugar in sausages. I mostly eat family
made sausages and I don’t think there’s much sugar.
~~~
KozmoNau7
Salt isn't dangerous, as long as you get enough fluids, your kidneys are
healthy and you don't overdo it. In other words yeah moderation is key, but
sausages (and other cured meats) can have a surprising salt content.
Sugar routinely gets added to a lot of foodstuffs you wouldn't expect it in.
But if you're primarily eating home-made sausages, you're probably not going
to have any issues, they're mostly in processed and ready-made foods.

I am not sure, how appropriate this is, but a related question/poll:
there is the stereotype, that hackers/IT guys are in general fat/unhealthy.
But in my experience, this is not at all true. It might just be my circles of
people (mostly germans around 30), but most of the IT guys I know, take good
care of their body, eat healthy and do all kinds of sports. Even though some
are now starting to get lazy, the overall picture for me is, that most are
healthy, above average (compared to people of their age).
So I am curious, how the world is for other people here on HN?

People with higher education often take better care of their bodies. Here is
my theory: A couple of decades ago, IT didn't require much education, because
there weren't many schools doing IT. So many people without higher education
worked in IT.

I would go more with, a lot of sad, fat kids at home, discovered the world of
computers, where they could shine, because nobody cared how they looked in the
real world, it only mattered what they could do. And this stereotype
definitely still exists, I would be curious, how many of the HN crowd fit into
it, but I can understand, that nobody wants to out himself like that.
edit: and I believe every fat person, knows and knew, that being fat is bad,
but when you are sad and eating is your allmost only joy, what can you do?
Starving and give up that little bit of happiness?

I don't really understand - what's the catch?
Some other day I've heard the news they were sponsoring research that fat
makes you fat.
Capitalism baby - profit for shareholders - we need

Count the isles in your supermarket, how many of them are nearly 100%
dedicated to sugar and sugary products? Think back 30 years, is this the way
you remember it? Saying diabetes and sugar aren't related while in America
there is a massive influx of diabetes diagnoses is like saying your dog ate
your homework.

I find it hard to follow nutritional advise when there are so many charlatans
taking advantage of women trying to lose weight without any health concern.
A Medicine degree shouldn't be necessary in order to eat well.
Any reliable source where I can learn the 'nutritional 101' in layman terms?

Saw it on Netflix. Thought I saw it on youtube also for free, but can't seem
to find the video.

Only available on Netflix US and Canada as well as a handful theater
screenings. I've said it before but it almost seems as if those documentaries
try to limit their audience. I can't count the number of times I stumbled upon
interesting small, niche and independent documentaries only to find out that
they are only screening in a few limited locations worldwide without any
purchasing option in sight.

This doesn't surprise me at all.
It took almost 40 years to prove that smoking causes lung cancer.
Similarly, despite unambiguous scientific evidence, it still seems acceptable
to deny that man-made CO2 release into the atmosphere causes global warming.
There's actually a good book covering these two instances and others:
"Merchants of Doubt: How a Handful of Scientists Obscured the Truth on Issues
from Tobacco Smoke to Global Warming"
~~~

Common factor: Money to be made.
Tobacco was the core of many states' economies, and still remains a massive
industry which makes many people wealthy.
Dealing with CO2 emissions would have required dealing with fossil fuel use...
and that's _tons_ of money and power in play there.
Sugar is, at the very least, another substance people crave, and has been
making people rich for hundreds of years.
Delaying tactics are feasible when you have billions or trillions of dollars,
control regulatory bodies, own politicians, scientists, and armies of lawyers.
Delaying tactics on the orders of just a few decades means generations of VP's
and C-levels getting unfathomably rich, as well as key shareholders. So...
fuck the harm, delay, delay, delay.
The key is that you have to not give a shit about anyone other than yourself,
or be genuinely deluded.

> The key is that you have to not give a shit about anyone other than yourself
This is actually quite difficult. Despite its shortcomings (and perhaps
ironically) religion can be effective at convincing people to put others first
but I would say the default behavior in most people is "I only care about
myself and family first". This default behavior is exacerbated when people
follow the influence of greed, lust, etc.

StillBored
Its a double edge sword. Most religions require suspension of critical
reasoning as well in order to "take on faith" that which cannot be proven (or
is outright wrong).
The result is basically training people to be susceptible to propaganda.

When calories are controlled, there is no difference in health markers between
a high sugar diet vs low.

I wish someone could explain in detail what EXACTLY is meant by "sugar". It's
become an overloaded term.
When we say sugar, do we JUST mean refined, processed, isolated sugars of the
likes of candy bars, sodas, etc?
Or do we mean carbohydrates in general, which are broken down by enzymes in
our saliva (amylase) into sugars?
If the latter then can we conclude carbohydrates in general are cancer
causing? I'm no biologist, or medical professional, so this all gets really
confusing when you start thinking beyond the simple "sugar is bad" assertion.

Of the people I know who have been on a sugar-free diet, all of them continued
to eat carrots, even though carrots have an interesting amount of sugar.
[http://www.sugarstacks.com/carrots.htm](http://www.sugarstacks.com/carrots.htm)
So when people say they're on a sugar-free diet, I interpret that to mean they
are avoiding refined sugars.
~~~
anindha
The total amount of sugar is less important than the glycemic load and the
insulin response caused. Carrots are high in fibre.
"The glycemic index is a value assigned to foods based on how slowly or how
quickly those foods cause increases in blood glucose levels" [1]
Coca Cola® (63) vs Carrots (39). Higher is worse.

Coca Cola® (63) vs White Rice (72). Higher is worse. By using that logic,
chicken nuggets and Pizza Hut beat plain potatoes. Clearly not a good recipe
for a healthy diet.
~~~
anindha
Both pizza and chicken nuggets are higher in fat and protein so don't spike
insulin or blood glucose levels. The preservatives and additives make the
Pizza Hut pizza and frozen chicken nuggets unhealthy for other reasons.
If you were making your own baked chicken nuggets or pizza from quality
ingredients then they are definitely healthier than potatoes or white rice,
assuming the calorie intake was the same.
This is counter-intuitive to most people because of all the misinformation
around the benefits of a low-fat diet [1].

Fruits and vegetables are full of sucrose, it is the most commonly occurring
sugar in plants. If splitting more sucrose (or is fructose really the
problem?) increases your chance of cancer, it means very little on its own.
Would you get the same results if they matched the starches to the glucose
equivalent, rather than the same mass?
Which is why I don't see why they would bother to suppress a result like this,
but I guess the public interpretation would likely be the outrageous
"specifically refined table sugar _gives you cancer_ ", so I can't exactly
blame 'em for wanting to.

A 12 oz can of Coca Cola has _twice_ the sugar content of an apple, without
the beneficial fiber or vitamins.
How many Americans are obese because they eat too many fruits and vegetables?
An overwhelming majority are obese due to fast foods, soda, snacks, and
sweets... costing taxpayers _millions_ of dollars while companies profit from
the negative externality.
~~~
test6554
Where I come from, if a person buys and eats junk and gets obese, that's their
own fault, not the fault of the person who sells junk, and certainly not the
fault of taxpayers. Their additional costs should come out of their own
pockets.

That's an extremely short sighted way to look at things, which gives a
complete pass to a bunch of bad actors in the system.
Why is it always "personal responsibility", but never "corporate
responsibility"?
