Someone Stole My Title, Meta Description Tag and Page Rank - <AUTHOR> http://discountgeni.us/2012/07/31/help-someone-stole-my-title-meta-description-tag-and-page-rank/

<comment><USER3> 1) stop "reading up" on SEO on the internet. really. just stop it. now.

80% of everything written about SEO on the internet is bullshit (this means 8 out of the 10 articles you have read reduce your knowledge about SEO (and the web in general))

2) never ever mention the word page rank again. page-rank is thought-cancer (and does not mean what you think it means)

3) your site is indexed via your IP address <http://184.108.40.206/>, this site ranks for your obscure long tail search term. make a canonical tag to your main domain. then our site will rank for your obscure long tail search term. to understand canonical tags go to [http://googlewebmastercentral.blogspot.ch/2010/09/seo- starte...](http://googlewebmastercentral.blogspot.ch/2010/09/seo-starter- guide-updated.html) download the PDF and read it front to cover.

4) if you want to understand SEO, read a book [http://www.amazon.com/Search- Engine-Marketing-Inc-Companys/d...](http://www.amazon.com/Search-Engine- Marketing-Inc-Companys/dp/0131852922)

last but not least: stop worrying and complaining about scrapper sites. they are here to stay. try to make the best shop website around.

and as a side note: with a high probability your blogpost will - from now on - rank for "high quality Bitcoin hat" as it reached the front page of HN (it will get distributed a lot, via scrappers, HN web-app-websites, ...) and the blog post has - compared to your shop start page and your shop page - <USER2> content.

<comment><USER4> _last but not least: stop worrying and complaining about scrapper sites. they are here to stay. try to make the best shop website around._

This isn't a site scraper at play; the uggsblogs.org domain's DNS is pointing to btcgear.com's IP address. Easy enough to fix with a virtual host, but very different to being scraped.

<comment><USER3> you are correct, then a canonical tag will fix it for good and google.

</comment></comment></comment><comment><USER4> Something smells fishy here. Both uggsblogs.org and the original site at btcgear.com point to the same IP address (22.214.171.124), and have the exact same content.

At a guess, uggsblogs.org is trying to set up a pagerank scam where in the future they'll try to sell the domain to someone else with the false promise of a high PR value. Either that or the btcgear.com guys are attempting to create some drama in an unethical manner. My money's on the pagerank scam or a similar equivalent.

Edit: quick way to fix this would be to add a separate virtual host on the btcgear.com server for uggsblogs.org, filled with nothing empty content. Leave the scammers to then move on to someone else.

<comment><AUTHOR> OP here: try typing "uggsblogs.org" into a browser... NOT the same content... when I originally looked at it, I didn't click through. I didn't realize they had my same content.

Also, I paid my webhost extra for a dedicated IP, so I'm not sure how uggsblogs is showing my IP. Edit: never mind... they're pointing to me... not me to them.

<comment><USER4> _OP here: try typing "uggsblogs.org" into a browser... NOT the same content... when I originally looked at it, I didn't click through. I didn't realize they had my same content_

It's showing the same content for me when I try just that. Latest stable Chrome on Windows 7.

 _Also, I paid my webhost extra for a dedicated IP, so I'm not sure how uggsblogs is showing my IP._

Anyone can point a domain to your IP address; a dedicated IP address basically just means that the IP address itself belongs to your server, not that no-one else can point their domain at it. For a cheeky example, it took me under 30 seconds to set up this: <http://btc.moomoomoo.com/>

<comment><AUTHOR> My bad, I was hitting .com not .org.

Yeah, I realized that right after I posted.

</comment></comment></comment></comment><comment><USER5> Not to go on a complete SEO rant, but here it goes. Page Rank is next to useless, like that hangy thing in the back of your throat. Page title and meta description are a close second, but still needed. Kind of like a title of a book, these serve only to "introduce" your page to the search engines and the users. Content, content, content. That's where it really matters.

Despite what most people think, there IS useful SEO reading on the web. This is an excellent guide: <http://www.seomoz.org/beginners-guide-to-seo>

But, as another poster mentioned, something strange is going on here. How long has your site been live?

<comment><AUTHOR> We've been live for about a week.

<comment><USER5> It would seem, then, that Google is trying to figure out who's site is legit. Google generally has an "index everything and sort it out later" mentality. Quite a few sites I've build show up #1 for their target keywords right away, but within a few days they get buried again.</comment></comment></comment>


Critical Path Driven Development - <AUTHOR> https://medium.com/@rakyll/cpdd-critical-path-driven-development-6c2592fb8ea4 <comment><USER2> I've always developed this way and I'm surprised how often other developers will spend all sorts of time on tertiary tasks or will compromise the stability of the critical path for the sake of some abstraction.

Make it work, make it work correctly, expand from there. But it must always work.

One example I saw recently of this done wrong is Duo Lingo. That app's subscription's main feature is the ability to do lessons offline. The thing is, it almost never works and it's been buggy for years now because the app refuses to cache enough data and has poor syncing support.

How can you fuck up your principal revenue stream like that? It should be the critical path.

<comment><USER3> Same goes for process development. I have seen tons of people bloating processes to cover tha last imaginable exception and forgetting the core function. In the end the exceptions worked, the standard didn't.

</comment></comment><comment><USER4> This is standard PRINCE project management skills and what is most surprising is that we had to forget it and go focus on agile to remember the value of it.

If one has tasks that are fully independent, then one has no dependencies. Once you have dependencies (and almost everyone does) then you now have the capability for them to block other tasks, or to create slippage down the tree of dependencies.

Recognising a critical path and ensuring that those tasks always have higher priority is why project management is not something that should be over- simplified.

Apple Disables Trim Support on 3rd Party SSDs in OS X - <AUTHOR> http://hothardware.com/News/AntiCompetitive-Apple-Disables-Trim-Support-On-3rd-Party-SSDs-In-OS-X <comment><USER2> I don't think this is Apple trying to be difficult: SSD TRIM is buggy between all the different vendors (today even Ubuntu enables it only for Samsung and Intel SSDs by default), they want to guarantee that it works by whitelisting what they ship with, and the mandatory driver signing seems like a security improvement. If some third party wants to ship a signed kernel extension that works with their specific SSD (or generic ones, even) and supports TRIM, that should be possible.

FWIW, there is a third party SSD drive that works with Apple's default drivers for TRIM support; I suspect they're doing some sort of identifier spoof to fool the whitelisting code: [http://www.angelbird.com/en/prod/ssd-wrk-for- mac-929/](http://www.angelbird.com/en/prod/ssd-wrk-for-mac-929/)

<comment><USER3> Does this whitelist drives that report themselves as a manufacturer of "Samsung", or does this whitelist drives that report themselves as "Apple".

If it's the latter, then they've functionally prevented me from ever upgrading a computer that I've purchased from them to add a new, larger hard drive. Now I cannot purchase a Samsung SSD from a third-party and have TRIM support (despite the fact that they ship the same drive, only changing the name reported as the manufacturer). Worse, a cursory glance at the store suggests that they don't sell SSDs as accessories, so I can't upgrade my drive _at all_ and get TRIM support, even at crazy high Apple markup.

(I didn't find this advertised, but I suppose it's possible that the Apple Store may do this upgrade themselves, it seems totally crazy that Apple would completely prevent me from upgrading my disk.)</comment></comment>


The dark side of light: negative frequency photons - <AUTHOR> http://arstechnica.com/science/2012/08/the-dark-side-of-light-negative-frequency-photons/ <comment><USER2> The interesting bit is that solving the equations gives you a solution with a negative frequency. Generally those negative frequencies are ignored because for most people a negative light frequency doesn't make sense. But if you extend the analysis further you get a positive frequency light out of interactions with that negative frequency light. And the paper talks a bit about observing those second order effects:

 _"Here, we have shown how the same process generates a second, so-far- unnoticed peak that corresponds to resonant transfer of energy to the negative-frequency branch of the dispersion relation. "_

which means the negative frequency light was _something_ but what it means isn't clear. It could be the tip of a new way at looking at light, or it could be nothing. Some of the experiments it suggests with respect to gravity waves are interesting.

<comment><USER3> At the turn of the 19th century, physicists were quite sure that they had a complete model of the universe, with just two minor unsolved problems: The aberration of light / michelson-morley experiment (which required the theory of relativity to explain), black body radiation (which was eventually explained by quantum mechanics). Actually solving these unsolved problems turned physics on its head.

Negative frequency light might be just a weird artifact. Or it might turn physics on its head. I'd put money on the former, though I hope for the latter.

edit: fix typo "native frequency" -> "negative frequency"

<comment><USER4> Those examples were deviations of reality from prediction/model. This is sort of the opposite -- the model predicts negative frequency light but we ignore this because it doesn't match what we thought reality was doing. Now we see that there is some tangible real-ness to these solutions. It may have interesting applications, but it wouldn't require us to change the theory (since the theory already predicts it correctly).

<comment><USER5> There's a lot of this kind of thing about. Black holes and the big bang arguably started life in this category, no?

</comment></comment></comment></comment><comment><USER6> I love the way that math reveals ultimate truths. We consider math to be some abstract thing that we're applying to help explain reality. Instead, it often appears that the abstraction is somehow the True Reality(tm), and our reality is really just an imperfect view of Math(tm).

We view math about like we view electromagnetic waves with our eyes. We see effects of it and reflections and complex interactions of only small parts of the em spectrum.

It's interesting to wonder if we could develop a way to "see math" in its pure form.

(Sorry, Friday afternoon speculation... not currently taking any drugs.)

<comment><USER7> Math is but a medium for modeling. Any model can have predictive power.

The challenge is in determining which surprising aspects of the model have faithful correspondence to the domain and which are nonessential artifacts of the modeling medium.

<comment><USER8> No.

The surprising thing is that the models generate predictions far beyond the domains they were designed for (and far beyond the original knowledge of the people making the models), and that the predictions are so mindbogglingly accurate that there seems to be Something Else going on.

See the Unreasonable Effectiveness of Mathematics link below.

<comment><USER7> No?

Surprising thing: Math's not the only modeling medium that can be Unreasonably Effective.

Unreasonable Effectiveness of Mathematics: Know; saw; upvoted apropos reference already.

<comment><USER9> I'm confused by your statement that "Math's not the only modeling medium that can be Unreasonably Effective", because it's not clear to me what the notion of a "non-mathematical model" means. (That is to say, it's not clear to me that you're even correct in the weaker assertion that "Math's not the only modeling medium.") Can you explain?

<comment><USER7> Modeling media besides math: digital electronic circuits, analog electronic circuits, legos, quantum mechanical phenomena, gears, computer simulation, wetware, mythology, clocks, BZ reactions, ...

<comment><USER9> Several of those are, in fact, math. (In particular, computer simulation.) The others are mostly phsyical models, which I must admit, I had not thought of. So that yields two; mathematical models (that is to say, formal models) and physical models (that is to say, real-world models). (The line can perhaps be a bit blurry in the case of e.g. digital electronic circuits, but, well, I'm not claiming there's a sharp line.)

That leaves "mythology", which I'm not convinced is a proper modeling medium at all.

</comment></comment></comment></comment></comment></comment></comment><comment><USER10> Here's the paper (PDF):

[http://physics.aps.org/featured-article- pdf/10.1103/PhysRevL...](http://physics.aps.org/featured-article- pdf/10.1103/PhysRevLett.108.253901)

It's about observations & theory where you can get waves in Cherenkov radiation which propagate against the dominant direction.

</comment><comment><USER11> This reminds me a lot of the observation that the double-slit experiment still produces interference patterns when you send particles instead of waves, and them even when you send those particles one-by-one in order to exclude the possibility of inter-particle interference.

</comment><comment><USER12> I read the original article that is much clearer about the details ( <http://news.ycombinator.com/item?id=4429424> ).

My explanation of the effect is long a bit technical. I hope that it is intelligible.

(To keep this simple, I will ignore the phases of the waves.)

* * * Complex notation:

First, the equation for the electric field of the light is

      E = A cos(kz-wt)

It's more convenient to write it as a sum of complex exponentials

      E = A [exp(i(kz-wt)) + exp(i(-kz-(-w)t))] /2
      E = Re( A [exp(i(kz-wt))])

By the linearity of the equations, the exp(i(kz-wt)) part and the exp(i(-kz-(-w)t)) have the same behavior, so you usually write simply

      "E" = A exp(i(kz-wt))

and solve everything as if it where a complex function, but just before writing the final version or going to the laboratory you must remember that the other part was there, and that the real physical object is the real part of the function.

* * * Standard non linearity effects:

If the media is linear but not uniform, there appear other waves that travel in other direction z' (reflection/refractions). All of them have the same w.

      "E_tot" = A exp(i(kz-wt)) + A' exp(i(kz'-wt))

Really all of them have two parts, one with w and the other with -w,

      E_tot = A/2 [exp(i(kz-wt))+ exp(i(-kz-(-w)t))] + A'/2 [exp(i(k'z-wt))+ exp(i(-kz-(-w)t))]

but usually you simply ignore that details, and only put a +cc (complex conjugate) or Re at the last minute.

If the media is no linear there can appear waves with a different frequency w'.

      "E_tot" = A exp(i(kz-wt)) + A' exp(i(k'z-w't))

(There can appear more than two exponentials.)

Again they have two parts, and the real thing is the real part. It's more clear to choose w' as a positive number, because (-w') will appear in the hidden part of the equation.

      E_tot = Re("E_tot")

* * * New non linearity effects in this article:

In this article they use a very sharp pulse in a very non linear material. So, from the

      "E" = A exp(i(kz-wt))

part they get two new exponentials

      "E_tot" = A exp(i(kz-wt)) + A' exp(i(k'z-w't)) + A'' exp(i(k_n''z-w_n''t))

where k' and w' are positive numbers as expected. But k_n'' and w_n'' are negative numbers!! They get this numbers from the same equation that has k' and w' as a solution, so all of them appear from the same mathematical term. They call this negative solution "NRR".

But it is important to remember that the original E has two exponentials, so you must repeat all the computations with the other part

      "E*" = A exp(i(-kz-(-w)t))

everything is equivalent, so after some recalculations you get

      "E*_tot" = A exp(i(-kz-(-w)t)) + A' exp(i(-k'z-(-w')t)) + A'' exp(i(-k_n''z-(-w_n'')t))

where every k and every w has an additional "-". They call this part "NRR* ". But now -k_n'' and -w_n'' are positive numbers. We can change the names, and call

      k'' = - k_n''
      w'' = - w_n''

and now k'' and w'' are positive numbers. So the first part of the solution is now

      "E_tot" = A exp(i(kz-wt)) + A' exp(i(k'z-w't)) + A'' exp(i(-k''z-(-w'')t))

and the second part is

      "E*_tot" = A exp(i(-kz-(-w)t)) + A' exp(i(-k'z-(-w')t)) + A'' exp(i(k''z-w''t))

And the real physical object is

      E_tot = ("E_tot"+"E*_tot")/2

So we can regroup the term. We exchange the terms with k'' and w'' that have the wrong signs from on part to the other, because the sum doesn't change.

      "E_totx" = A exp(i(kz-wt)) + A' exp(i(k'z-w't)) + A'' exp(i(k''z-w''t))

and the second part is

      "E*_totx" = A exp(i(-kz-(-w)t)) + A' exp(i(-k'z-(-w')t)) + A'' exp(i(-k''z-(-w'')t))

and as before

      E_tot = ("E_totx"+"E*_totx")/2

Now the interpretation of "E_totx" is straightforward. From the original field "E" you get three waves, with frequencies w, w' and w'', all of them positive. And in "E* _totx" is the complex conjugate part, so the final result is real.

And they can measure the three waves.

* * * Notes:

Usually, the A'' coefficient is so small that all this strange part can be ignored, but they were able to measure it in the laboratory.

One important detail is that k/w, k'/w' and k_n''/w_n''= k''/w'' are all positive, so they represent waves that travel in the same direction.

<comment><USER13> At times like this I think it's a shame that HN doesn't support TeX formatting. It's much easier to follow a mathematical argument with proper notation.

<comment><USER14> mathbin.net

<comment><USER13> Yes, or any image archive, with appropriate homework in advance of posting. Or an online LaTeX editor like mine:

<http://arachnoid.com/latex>

But better, there are some very low-impact JavaScript utilities like MathJax:

<http://www.mathjax.org/>

Which allow a pretty seamless interleaving of LaTeX and normal content within a page. Within a submission one need only enclose the LaTeX content in unique delimiters, like the often-used $$double-dollar-signs$$.

All this because W3C can't seem to agree on a standard way to render mathematics in the browser itself -- or more to the point, get the browser builders to agree to anything they've proposed.

</comment></comment></comment></comment><comment><USER15> This reminds me of P and N silicon; the negative frequency light is like hole current. (N silicon has "extra" electrons. P silicon has "missing" electrons that leave "holes", and you can have current where it's the holes that are moving.)

</comment><comment><USER16> I still don't get what a negative frequency is. The frequency is the number of times something happens in a given amount of time. Would a negative frequency be the number of events that were expected to happen but didn't? If so, how could this be differentiated from an error in our expectations.

<comment><USER10> Physics often uses the sign of a frequency to indicate the direction of travel with regard to a reference frame.

E.g. 2 Hz is a wave oscillating two times per second and travelling to the right, -2 Hz is the same travelling to the left.

In some cases direction isn't really meaningful (standing waves, or the height or pressure of a medium as seen by a stationary observer). In others, the direction of propagation can be quite significant.

<comment><USER17> Is a -2 Hz wave travelling to the right the same as a 2 Hz save travelling to the right, but going backwards in time?

Could there be something to John G. Cramer's transactional interpretation of Quantum Mechanics? Instead of probability waves collapsing instantaneously, could everything be mediated by photons going backwards in time?

<comment><USER18> The problem with such interpretations is that they violate causality. Check out Wheeler-Feynman absorber theory for history. Concepts such as collapse of a wave function aren't necessary when you stop treating the observer in a special way and start considering observer-particle as a big quantum system.

<comment><USER19> Causality would not seem to be broken if the effects were shunted to an adjacent universe. This would directly assume that MWT is indeed true.

</comment></comment></comment></comment></comment><comment><USER20> How exactly would light at "negative green" frequency be perceived by an eye/camera, when mixed with an equal amount of regular green? Would it cancel out, would the negative light have no effect, or would the powers add constructively?

<comment><USER11> The article doesn't indicate what the physical manifestation of negative- frequency wave would be. It only reports the observation of a positive- frequency wave that seems to require the transient existence of a negative- frequency intermediate.

This is similar to how particles like the Higgs boson are not directly detected in particle accelerators, but are inferred from the directly- observable particles that they produce. The difference is that physicists are (I think) pretty sure that the Higgs actually physically exists, if only for a short time, while the same is not clear for the negative-frequency intermediate wave described here.

</comment></comment><comment><USER21> Ok, so, this doesn't mean I can have a light bulb that makes the room dark?

<comment><USER22> You don't need anything fancy like negative frequency light bulb for that, only a regular light bulb that emits light 180 degree phase shifted to the already existing light in the room. It's actually impossible to do with a light bulb because the light that emits is not coherent but you can do it with a laser if the incoming light is also from a laser, in fact negative and positive laser interference is the basis for several technologies such as holograms.</comment></comment>

Leadership is never given, it's taken - <AUTHOR> http://www.trixbox.com/about-us/blog/leadership-never-given-its-taken <comment><USER2> "Got an idea that you think your managers are missing? Tell them? They don't like it? Tell their bosses? They don't like it? Tell the CEO. Stand on his or her desk if you have to – shout your reasoning, advocate for your customers, do what you have to do. Think you are gonna get fired?"

YES. In the vast majority of large corporations you will get fired before you even have the chance to get near the CEO's desk. Every single outspoken person I've known in large organizations has gotten laid off or canned outright. People who "take" leadership are seen as a threat to those who already have it and are eliminated.

The first or even second level managers don't even have a say. Unless your title is at least "director" you don't have a prayer in implementing any real change in the organization. The problem is, most directors are "yes men" who've risen through the ranks and are more interested in protecting their power than improving things.

Want to take leadership? Work for a smaller company where you might have more say, or start your own company like the author of the article apparently did.

<comment><USER3> Rubbish (with one caveat). It is certainly possible to make change happen, even in huge companies.

The caveat - you have to do it the right way, and make the most of your advantages. (Being a new graduate or studying something work related, for example, is a massive advantage as it gives you a credible excuse for 'being keen'.)

The right way:

\- Work out what should be changed and why. Condense this into a easy to follow thirty second pitch that is hard to argue against.

\- Get friendly with your target's secretary. CEO's secretaries are people too, and spending ten minute's a day for a month getting to know her is a vital part of the plan.

\- Sell the idea to your line manager. You are _not_ asking for permission, just covering your back from later fallout (hey, you gave him a heads up and he didn't stop you...). His feedback can sometimes be useful too. His objections may need to be addressed in your pitch.

\- Get your target's secretary to book you in with him for fifteen minutes. If your idea isn't good enough that she is willing to do this, despite your new friendship, it sucks and you need to rethink anyway.

\- Pitch and cross your fingers. Your general competence, politeness and ability to cut through the system while working inside it will mark you out as someone to listen to. At this stage your idea might get bounced, but in my experience this is rare if you have a real problem, a good resolution, and a cost effective plan to go from here to there. Usually the only downside is that you get put in charge of making it happen - so be sure to have a list of things you need prepared.

You might think to yourself that this sounds like an awful lot of work to get an idea implemented, but it does work. It's also fantastic practice for selling your own product later, as these steps share a lot in common with a typical sales process.

The wrong way:

\- Mumble something incoherent or badly thought out to your boss. When he 'doesn't get it' repeat it to his boss. Keep working up the chain, without ever taking a bath or wearing a suit, until every manager in the whole organisation thinks you are an irritating pillock. Then for an encore repeat the same unresearched assertions in front of the CEO (but more vehemently), having alienated your local managers to the point that they won't stand up for you.

<comment><USER4> This is what is wrong with Corporate America today. Why should you need to work the system? That's why some startups are a lot more successful, they're just a lot more efficient while the awesome-hacker-in-big-company-is-still- getting-to-know-the-CEO-s-secretary :-)

<comment><USER5> I would argue that there are no contexts where "working the system" isn't necessary for success, including startups. The systems you have to work here can even be more difficult because they are distributed -- investors, potential customers, etc. More like seduction than working your way to the top of a prison gang, but "working the system" nonetheless.

"You have to work the system" can be shortened to "You have to work". You have to do things that are uncomfortable, that you think you shouldn't have to do, in order to succeed.

<comment><USER4> Yep, but you still need to make a decision about which system you should be working in order to maximize whatever it is you're trying to maximize.

If you're trying to maximize wealth, iterating and failing fast is a much better way to do it as opposed to kissing middle-management ass, what's the point of working that system?

<comment><USER3> Hmm, not sure about that. Taking a arbritrary threshold of $500k a year, I have friends who earn that on boards of FTSE250 companies - there are maybe 2,500 of those jobs just in the UK (10 per company). At the top end exec compensation hits $40m+ which is equal to a huge startup cash out.

How many startup founder positions are there that pay over $500k a year? How many $40m+ wins are there per year?

Writing off the corporate route to weath might be a mistake, there are too many factors just to dismiss something as black and white. By the time you start considering risk, competitors and everything else it gets very complicated indeed. The fact that it isn't something you want to do personally doesn't make it a bad choice for everyone.

</comment></comment></comment></comment></comment></comment><comment><USER6> 1) Many corporate environments are built around a lack of trust. Generally this parades as "quality assurance" or "change management". There's certainly a place for QA and change management - the problem is that those processes often intervene -before- a change takes place. Beneficial change, however, is not always obvious prior to implementation. So say some plebe in app management has an idea for restructuring the UI of a particular sub-section, but it gets nixed because "The users won't understand" or "We'll have to retrain." A) This could be the change that would make life easier for the people who interact with that screen, they just didn't know it; B) Even if there's a mock-up, it's not the same as using the system. Now certainly there's a real cost to change, but most organizations are restrictive rather than permissive. This makes the "fight for change" really hard.

2) Bad corporate managers view ideas as a threat, if they didn't buy in. Say you have an idea that could alter your company for the better. If your manager rejects it and you push the issue, you better watch your back. (As a manager this is a hard impulse to overcome if you let yourself get 'sucked into' the corporate environment. Instead of being angry that someone "went around you", realize you missed a good idea (it's ok!) and try and figure out how to make it the best implementation possible.)

3) People are delusional. The linked post talks about people who think they have good ideas. In 'bitch and moan' sessions I've witnessed at conferences, eating with colleagues at lunch or whatever, I hear about how their great ideas are being ignored. Their ideas aren't great. They've come to be ignored because they're the Dwight Schrute of their office. So telling people to 'take leadership' is actually really bad advice.

<comment><USER7> On the last point, I often wonder if I am delusional or not. It helps to find a few fellow engineers who are willing to listen, understand and tell you when you're smoking crack. Of course you should be ready to extend the favor yourself.

<comment><USER8> I brainstorm a lot, and I like to bounce ideas off my fellow engineers. I've found the most effective stratety to getting buy-in is 1) awareness -- usually via link sharing 2) conversation around the lunch table -- weeds out 85% of ideas 3) more conversation, this time during meetings, where the positive of X is brought up in contrast to what happenes now and then, finally 4) proposal. Slow and steady wins the race. You don't want to trigger people's fight or flight response.

</comment></comment></comment><comment><USER9> Okay I really like the message that is being sent in this article.

But whether it works really depends on the company culture. You gotta remember that for each individual employee, his/her incentive is NOT to do what benefits the company the most. His/her incentive is to do what benefits HIMSELF/HERSELF the most. So it is up to the company to create a culture where doing what benefits the company the most also benefits the individual the most.

For many many companies this is not the case. Due to internal politics or the ego of managers, it is often to the benefit of the individual employee to shut up and do the stupid thing. GIGO you know. Why should I speak up and make the company $100 million dollars, if it means my manager will get mad at me and my raise goes down by 1%?

</comment><comment><USER10> I think this is more of a leadership problem than anything else.

I think one of the goals of a leader is to create an environment in which people feel good about bringing their ideas to the forefront. They shouldn't be punished for being outspoken.

I agree with coglehtorpe that in many large organizations such a person would get fired.

I think employees can speak up but before they do they should assess the situation.

I don't know if your chances are better in general in a small company. I have been in small organizations where the CEO is a bully and don't really care for much feedback.

The trick is to work for an organization large or small whose culture favors such a behavior for e.g. GE under Welch or some of today's great companies when they were small etc.

What I can say from experience though is that a company that favors employees to speak and one that values their opinion is a superior company.

</comment><comment> daniel-cussen A self-appointed CEO / Janitor's perspective is going to be very different from pretty much everyone else in the workforce. Many leaders in middle- management literally got "'ass-kicking-certification plaques' at [their] doorstep[s]..." in the form of an acceptance letter to business school. As coglethorpe said, doing end runs around your superiors _will_ get you fired.

This guy's cool and all, but he's on a plane that does only intersects with corporate America at the talent pool of sheepish employees.

Netflix rethinks its Hollywood ambitions - <AUTHOR> http://www.marketwatch.com/story/netflix-rethinks-its-hollywood-ambitions-2017-04-17 <comment><USER2> Misleading title. The war about the theatre window is still ongoing, and even advancing than declining. Netflix just got two major movies into Cannes, Amazon didn't even try with their hit Manchester by the sea. Theatre chains are already beating the drum against the Cannes directors, who are supposedly helping killing quality movies by selecting Netflix movies. Looks like Netflix won this fight, and the more publicity it gets the better for them. The parallel movie start is just good promotion for their streaming services, which generates revenue without all the high costs involved in theatres.

Amazon might rethink it's strategy also, and then the studios are really fucked because then they missed the boat.</comment>

Space Cadets and Rat Utopias - <AUTHOR> http://theappendix.net/issues/2014/7/space-cadets-and-rat-utopias <comment><USER2> I certainly agree with the idea that a fairly large amount of private indoor/outdoor space is conducive to happiness and mental health. The tendency of central planners to want everybody to live in a small space and commute by public transport in the name of "efficiency" and "the environment" is depressing. Let's all have half an acre of land, a nice car, and a properly planned road system so we can all get from A to B without running into too much traffic. (Of course you'd want walkable town/city centres as well.)

I don't think we need to centrally plan our society to make people happy, we just have to stop getting in the way of letting people have what they want.

<comment><USER3> What you're proposing is the status quo, which leads to environmentally and economically bad situations. You're basically describing the false claims of suburbia. Giving everyone a half acre, a car, and the infrastructure to support that would cause deforestation and a lot of pollution. Not to mention the encroachment on the habitats of many animals already under stress due to loss of habitat. I'm sorry, but a backyard (with the noise of your neighbor mowing their lawn, blowing leaves, etc) is not similar to being in a remote area with a great view. As with suburbia, this research seems rather outdated.</comment></comment>

All Of Argentina, Uruguay Without Electricity After Massive Outage - <AUTHOR> https://www.ndtv.com/world-news/massive-power-outage-hits-argentina-uruguay-power-companies-2054203 <comment><USER2> We just went through a couple of outages in Venezuela. The first one was 5 days, the second one 3 days.

After day 2 you start getting worried because everything failed, including the water service (they've been badly maintained and they don't generate their own power) and cell phone service. Lots of already scarce food was lost because people had no way to refrigerate it. At least it made for some nice neighborhood cookouts were everyone cooked and shared their food in the street.

Getting in touch with my parents in another city was like sending messages in a bottle. I sent an SMS, once a day they moved to one of the few places where there was still cell phone service and replied.

Since the main issue that caused the huge outages hasn't been resolved yet, we still get daily power rationing. I'm sitting here in the dark typing, 4 hours so far without power.

Hope the situation in Argentina gets resolved quickly!

<comment><USER3> It's very sad that while you are going through all this, in other parts of the world where the situation is far better, the only interest in Venezuela seems to be how they can use it to support their political claims.

For instance in Spain, leftist people refuse to acknowledge how bad the situation is because they link Chavez and Maduro with their ideas and somehow think that it would show weakness in their ideology, specially for some politicians that openly praised Chavez.

On the other side, right wing people want the situation to be as bad as possible so they can use it as a proof of how harmful the left is for a country.

So Venezuela will pop up again and again in political discussions, but the important issue seems to be "my ideology is betters than yours", not helping the people.

I really hope it gets better for you.

<comment><USER4> In the United States it's the same, but the left don't even take it as an example of socialist failures. Instead they attribute the state of Venezuela to having been the consequence of American interventionism. It's actually a tragedy, because the lessons to be learned from the failure of socialism come at the cost of countless lives, the least we could do is come away with something of utility.

<comment><USER5> Alas, your argument is tragic because with just a simple switch of a phrase, it becomes even more truthful:

>It's actually a tragedy, because the lessons to be learned from the failure of western imperialism come at the cost of countless lives, the least we could do is come away with something of utility.

We in the West all too often ignore the victims of Americas heinous illegal wars - over 500,000 innocent people have lost their lives because America believes it has a right to interfere in sovereign states across the globe.

Whether you are left- or right- oriented, you will be doing yourself and your culture a favour by stopping the very poor habit of ignoring the real victims of America's wars, who have too long been swept under the covers, because its either too embarrassing or the inherent evils too obvious upon inspection.

Americans of all political persuasions really need to stop America's war machine. It is, undeniably, the most negative influence in the world today.

<comment><USER4> I oppose all American interventionism. I think it's horrible. That being said, it's not the reason why the Venezuelan state failed.

<comment><USER5> Venezuela would be in a much better condition today if the CIA was not interfering in its internal politics. There can be absolutely no doubt about this - the evidence is absolutely clear to those who care to look.

To discount the negative effect that CIA interference in the normal operation of sovereign states has on the world, one has to be willing to fall for a hell of a lot of propaganda and lies. The CIA is one of the most evil organisations on the planet today.

<comment><USER7> I don't understand why BsAs temperature would drop just because the e got knocked off, or why it ceases to be an analog function after the cut :S

<comment><USER8> My guess would be that it's an average of several temperature sensors, and that a sensor going offline registers as zero. So when the sensors come back online, there's a sudden jump in the calculated average temperature.

<comment><USER9> The power drops so often that Argentina would be quite a bit warmer than officially registered here if it were true.

</comment></comment></comment></comment><comment><USER10> Argentina is world's eighth largest country. I find it mind blowing that you can have a power outage that covers the whole country (+ some more).

<comment><USER7> It isn't really though. A cascading failure can knock out an entire grid. The Northeast blackout is an example.

      A line goes out.
      while (there some lines are still live):
        The current redistributes itself among neighboring lines.
        Neighboring lines trip
      end
      BlackStart()

BlackStart() is fun. Having your plants and grid down is like having a dead battery (plants use ~30% of the electricity they gen on themselves) and no one to give you a jump.

Usually the hydroelectric plants are started first. Arg. is lucky, they have a lot of those. Otherwise you need to fire up diesel generators (which hopefully have been maintained).

You give power to the grid first so you can start another plant.

Then you feed hospitals and continue firing the thermal plants.

Throughout all of this you have to keep phase stability (no grid, no phase reference). I'd assume this would limit renewable's use-fullness for re-start (a thousand 5Mw turbines out of phase are best left idling)

As a last step you turn on your nuclear plants (Arg. has a few). These are last because of nuclear poisons that accumulate from decaying wastes that weren't burned while the reactor was off.

It's a bloody hard problem.

<comment><USER11> What do you do for a living, and how can I learn more about it? This stuff fascinates me and you've explained it really well.

<comment><USER12> The user is probably a transmission level grid operator. These exist at most decent sized utilities (Entergy, AEP, Duke), although it is possible there is a TOP (transmission operator company) that is not the same as the utility.

There are also organizations like the RTO/ISO that also act like air traffic controllers for the grid by keeping it reliable. They also are usually responsible for committing and dispatching generation for dozens of utilities collectively to save money (by banding together, you need to carry less reserves or backup power and can leverage economies of scale). In North America these organizations are (CAISO, SPP, ERCOT, MISO, PJM, NYISO, and ISO- NE). All of these organizations practice black-start drills (I used to help run them) and have NERC certified operators.

<comment><USER7> "The user is probably a transmission level grid operator. "

Close. My dad's a power engineer, specifically grid protection.

<comment><USER12> If he's doing grid protection he's probably in distribution engineering and they would be pretty involved with a black start drill from as in they or the line crews with their boots on the ground as not all of that procedure can be initiated remotely I'd imagine.

The transmission level engineers and operators will call the shots as far as how the high level stuff goes down. In other words they'll issue a directive to get unit x online and then close in breaker b and clear a path to unit y while picking up load at z. The actual process from the end of the people doing that work is likely to be significantly more detailed.

<comment><USER7> "If he's doing grid protection he's probably in distribution engineering and they would be pretty involved with a black start drill from as in they or the line crews with their boots on the ground as not all of that procedure can be initiated remotely I'd imagine."

</comment></comment></comment></comment></comment></comment></comment><comment><USER13> I was going to post this. Thanks. Looks like Uruguay, Paraguay, south of Brazil, Bolivia are also affected. Several million people. It's raining, no internet, this will be a long Sunday. Also today is father's day, will be a celebration with candles like in XIX :)

<comment><USER8> > south of Brazil

That sounded strange to me, since Brazil imports power from Uruguay and Argentina through somewhat small DC links, and if only them failing is enough to cause a blackout in Brazil, something was probably not configured correctly. So I went looking, and according to [https://g1.globo.com/mundo/noticia/2019/06/16/apagao- deixa-m...](https://g1.globo.com/mundo/noticia/2019/06/16/apagao-deixa- milhoes-sem-energia-na-argentina-e-no-uruguai.ghtml) "deixou sem energia toda a Argentina, Uruguai, Paraguai e sul do Brasil", so Paraguay was also affected. Paraguay shares the huge Itaipu dam with Brazil, and a large amount of power in Brazil comes from the Itaipu dam, so if Paraguay was affected, Brazil (mostly the south and southwest) will probably also be affected.

edit: the realtime graphs at [http://www.ons.org.br/pt/paginas/energia- agora/carga-e-gerac...](http://www.ons.org.br/pt/paginas/energia-agora/carga- e-geracao) show a loss of around 1.3 GW of hydroelectric generation in the south region starting around 7:00 and ending around 10:00, matching the timing of the blackout.

<comment><USER14> According to Paraguayan news [1] (Spanish), the failure was on the Argentina side of the Yacyretá hydroelectric (which is shared by Argentina and Paraguay), not at the plant itself. Only a few Paraguayan towns close to the hydroelectric itself were affected, while Argentina and countries it resells electricity to were out of power.

<comment><USER15> I can confirm, at Paraguay, only two small towns (Pilar y Ayolas) where affected and for a short period of time. Source: I live at Paraguay.

<comment><USER14> Nice to see Paraguay present here on HN, I live here in Asunción.

I also heard of some people near Luque without power Sunday and Monday, but I'd guess it was an unrelated ANDE incident.

</comment></comment></comment></comment></comment><comment><USER16> How resilient has the cellular phone network been in this outage?

How resilient is the municipal water system in an outage like this?

Do most people in Argentina and Uruguay cook with (piped/tank) gas or electric ranges?

<comment><USER17> I haven't tracked the cellphone network status continuously, but here in Buenos Aires, I had a VoIP call from 8:30 to 9:00 which worked fine. Until it didn't, at about 9:00, but that's par for the course with fucking Movistar. I was using cellphone data because the power was out in the house. I didn't realize it was out in the entire country.

Here in Argentina, municipal water is totally reliable (I've never heard of a water service loss due to a power outage), but the pressure in the pipes is so low that every individual house has a pump to raise the water into a rooftop tank. These pumps are invariably electric and powered from either the grid or, on the frequent occasions that doesn't work, a generator. Municipal water typically has service losses a few times a year, but not due to blackouts.

Gas stoves are far more common in Argentina than electric stoves, although my apartment has an electric stove, which has a short which electrifies the stainless-steel surface of the stove when it's turned on. Most people in and near the capital run their gas stoves and on-demand hot-water heaters from public-utility natural gas, supplied by local monopolies (state-owned in some cases). Propane cylinders are common in less-populated areas and in houses where the gas piping has been disconnected from the public utility, usually due to billing disputes or safety concerns.

Over the last few years, the utilities have been sandbagging gas reconnections after disconnections due to safety concerns, often allowing them to leave unprofitable customers disconnected for years at a time once someone has called in a gas leak, while they wait for the government price controls (which have fallen far behind our absurd levels of inflation) to be loosened, making those customers' business profitable again. This has been a significant reason for new installations of electrical cooking and hot-water-heating appliances. A court recently ruled against this practice, and so gas reconnections have been sped up lately.

Uruguay has much less use of natural gas, for regulatory reasons: gas appliances can only be installed indoors if the room in which they are installed has a window to the outside that cannot be closed, thus removing the risk of explosions in the case of a gas leak. Consequently in Uruguay gas stoves are almost unheard of, and nearly all cooking is electric. Many hot- water heaters in Uruguay are still the gas-powered tankless type that is nearly universal in Argentina, though. They're just installed outdoors.

(Actually, I'm not sure if the above information about Uruguay applies outside of Montevideo.)

I hope this information is interesting to you!

<comment><USER18> Not OP, but deeply interesting to me and especially so as I travel around South America.

I am completely fascinated by the home infrastructure choices in different parts of the world. I'm currently in Sao Paulo and the hot water setup is a little scary. There's no hot water reserve or hot water plumbing at all.

The only hot water source is in the shower. It's heated electrically in real time by a 5000W appliance that sits just above the shower head. The only way to change water temperature is by turning a knob on the appliance. In homes with bad grounding, this results in shocks often enough that my hosts have shown me Brazilian memes about it.

<comment><USER17> Yeah, electric showers are common in much of Latin America. In theory you could build them to be safe, but often they aren't. I showered with a tank- based electric shower today: you fill the tank, plug it in until it's hot, unplug it, step underneath, and open the valve. This arrangement has less risk of electrical shock, but it's far less convenient. Because the power was out, I filled it with hot water from the tankless gas heater, but it was able to cool enough in the process that it was more like a lukewarm shower than a hot one.

<comment><USER19> Many of the showers in Scotland are electric too, but they look much more modern and safe than the Asian and South American ones I've seen on the internet.

<comment><USER20> The difference is that in Scotland and Europe, it's just one or two insulated heating elements that the water flows past. There are numerous safeties, overheat protectors, usually an RCD - in short, you'd be very unlucky to get a shock.

In South America, I've seen two types. One: an element, but it's uninsulated and has no safety features. This is usually operated by a water pressure switch and operates by heating a thin resistive element up. High danger of faults to earth (you're earth).

The other kind has me rather gobsmacked - the water is the element. The idea is to just pump in enough juice that the water starts to flash boil, and forms a plasma channel that then heats the surrounding water. Ostensibly safe, if earthed, but I really disliked the 60hz skin tingle - later discovered that they'd hooked earth up to the third phase in that house, when I plugged my laptop in. Metal case, leg, funky chicken. I guess the shower is reliant on skin effect to not kill you.

There's a really great YouTuber who is forever tearing domestic appliances apart - it's actually quite amazing how some stuff is built, both in a good way and a bad way.

<comment><USER25> >There is a common misconception that the number one driver of TV pickup is the boiling of kettles. In fact, this only creates a pull on the local network for a short period of time until the water has boiled, and can therefore be managed relatively easily, whereas flushing the toilet causes a longer surge at the water and sewerage pumping stations, and opening the refrigerator lets the chilled air escape, causing the compressor to run. These loads are more of a problem for the grid.

In this case, of the electric grids. In USA there are a few huge transformers that can be knocked out with an EMP, carrington event or otherwise, and plunge the USA into a similar situation.

We need to decentralize:

Electric grids (solar, etc.)

Cellphone towers and ISPs (mesh networks)

Social software and collaboration (open source software platforms to replace Facebook and Google)

I am a big believer in this, and I have led Qbix to reinvest nearly a million dollars of our company's revenues to build towards this future:

<comment><USER35> Decentralizing would mean more frequent local power outages as you cannot meet demand with local generation.

Decentralizing would force lower efficiency on power generation.

<comment><USER34> Decentralization doesn't mean you can't have a market for energy, and interconnections.

<comment><USER35> For an electric grid it kinda does.

<comment><USER34> Why is that?

Multiple sources of energy generation and the option to participate in voluntary exchanges.</comment></comment></comment></comment></comment>


Decades Ago, MDMA Was Used in Marriage Counseling - <AUTHOR> https://bigthink.com/sex-relationships/decades-ago-mdma-was-used-in-marriage-counseling <comment><USER2> _...Naranjo 's partner, Alexander Shulgin, synthesized the more commonly known MDMA, which proved to be less hallucinogenic and less toxic than its original formation._

As a Web Developer, how can I buy my client's business? - <AUTHOR>

Over the past 3 years I have built and have been running an entire infrastructure for a client who I believe is selling his services to the wrong industry. Right now he is making $46k per month but in another industry with the right contacts he could easily be making $161k per month.
I believe I could purchase the infrastructure off of him which I could improve and maintain on an ongoing basis but to do this I would need to find the money to buy $276k of assets (book value) and someone with contacts in another industry.
I feel I need to act quick to get this deal but I have no idea where to go. I know the tech side of this inside out but I need some good people to partner with.
There is almost no risk because the purchase price is the value of the assets but I physically can't do it on my own. <comment><USER2> Typically this is what you can take to high net worth people and discuss it with them to help back you. That means you will instantly have 1 or more partners, but it is doable.

Couple of other options, Leveraged Buy Out, where you purchase his business over the period of say 1 year, during which time you guys split the net income. These are tough to get right and have everyone see it as a win-win, sometimes you give up 2-3 years of 50% net income, plus a 25-75% down payment. The more amount of money you put in the better deal you get. A lot of small businesses are sold this way, just not talked about a lot in the tech circles.

Combination of things, bank loan, home equity, friends and family and maybe 1 or 2 high net worth people. Again, you wind up with lots of details to work through.

Last option, if you like this client, you could always try and partner with him. OR cut a deal that says you will bring his product to market in another industry and you want 75% of net income on it. You can even rebrand the product sometimes if the client is willing. He may see it as a win-win as he doesn't have all the risk to enter a new market, plus gets your attention to make sure things are running tip-top. Remember its net income, so he'd still pay you for upkeep of the current product within the market he is currently in. But new features or rebranding would be on you for the other market.

</comment><comment><USER3> Why do you think your client would sell you his business for the book value of its assets if it allows him to make "additional" $46k per month?

Also, wouldn't your client also sell his services to this other industry if he had the correct contacts? If you also do not have the correct contacts what makes you think you can create them better or more easily than your client?

If you have developed the whole system anyway, why not build a new one using your earned skills and experience?

<comment><USER4> > _If you have developed the whole system anyway, why not build a new one > using your earned skills and experience?_

One reason is integrity and the other is likely clauses in the contract he/she signed with his/her client.

<comment><USER5> Also time, It is not so easy to just go build a copy of an already working project. Getting the intricate stuff right is not so easy. + Reputation, He would have to start off with a fresh customer base.

</comment></comment></comment><comment><USER6> Why not offer a partnership? If you really do know how to triple the revenue, then you would have a most compelling argument.

</comment><comment><USER7> If there is no risk, it sounds like a good fit for a bank loan.

<comment><USER5> I guess he feels it would be hard to justify the no risk part to a bank and its employees who aren't so familiar with the said business or industry.

<comment><USER8> Banks are really good at understanding service businesses that have 46k of monthly revenue and sell for 276k. Profit would matter too, so if the margin is 50%, then we're looking at a ~11-month payback possibility.

Docker for Mac Beta Review - <AUTHOR> https://medium.com/@nzoschke/docker-for-mac-beta-review-b91692289eb5 <comment><USER5> I'm also in the beta, and I like it a lot. It's functionally equivalent to `dlite`, which Nathan LaFreniere has done an _extremely_ good job on. He deserves massive credit for making OSX Docker dev bearable and for providing the inspiration for "Docker for Mac".

A few issues I've seen:

1\. I cannot believe they are using `docker.local`. This hostname will cause nothing but trouble for years to come. DON'T USE `.local`! Apple has decided that `.local` belongs to Bonjour, and due to a longstanding bug with their IPv6 integration, you can expect to see a 5-10s random delay in your applications as Bonjour searches your local network to try to resolve `docker.local`. Yeah, you put it in your `/etc/hosts`? Doesn't matter. Still screws up. Use `docker.dev` or `local.docker`. [[http://superuser.com/questions/370559/10-second-delay-for- lo...](http://superuser.com/questions/370559/10-second-delay-for-local-tld-in- mac-os-x-lion)]

2\. -beta8 is screwed up. It won't bind to its local ip anymore. The only option is to port forward from localhost. Unfortunately, Docker isn't offering a download of beta7. Thankfully, I still had the DMG around. 3\. The polish is still lacking. Most menu bar items ask you to open up something else. 4\. Why "Docker for Mac"? Couldn't the team think of a less confusing name? Now I have "Docker" running "docker".

Otherwise - great projects, and again, much credit to @nlf for `dlite`. If you're not part of the beta, check out dlite ([https://github.com/nlf/dlite](https://github.com/nlf/dlite)). It's at least as good as Docker for Mac.

<comment><USER6> > I cannot believe they are using `docker.local`. This hostname will cause > nothing but trouble for years to come.

We are indeed moving away from `docker.local` in Docker for Mac. There have actually been two networking modes in there since the early betas: the first one uses the OSX vmnet framework to give your container a bridged DHCP lease ('nat' mode), and the second one dynamically translates Linux container traffic into OSX socket calls ('hostnet' or VPN compatibility mode).

Try to give hostnet mode a try by selecting "VPN compatibility" from the UI. This will bind containers to `localhost` on your Mac instead of `docker.local` and also let you publish your ports to the external network. One of our design goals has been to run Docker for Mac as sandboxed as possible, and so we cannot just modify the /etc/resolv.conf to introduce new system domains such as ".dev".

We've been iterating on the networking modes in the early betas to get this right, so beta9 should hopefully strike a good balance with its defaults. It's also why we've been holding a private beta, so that we can make these kinds of changes without disrupting huge numbers of users' workflows. Your feedback as we figure it out is very much appreciated!

<comment><USER7> A minor addition: to use 'localhost' in beta 8 you may need to also run the internal debug command:

      pinata set native/port-forwarding true

In previous betas this setting was implied by "VPN compatibility" mode, but in beta 8 it was made an independent setting.

In beta 9 using localhost will be the default -- as avsm says we've been iterating on the network configuration trying to find the most compatible / least surprising defaults. Hopefully after beta 9 it will be stable on "localhost".

</comment></comment></comment><comment><USER8> Same experience here, both on Mac and Windows. They've done a great job making it "just work". The user interface pieces are a bit raw -- perhaps "minimalist" or "unobtrusive" would put that in a better light! -- but clearly most of the work has gone into the lower level integration, where it shines.

Docker for Mac/Windows, once released, will nuke the ick factor on those platforms from orbit, which can only lead to even more adoption.

<comment><USER9> I hope there's going to be an easy way to package this with your own docker image in order to have a new way to distribute applications. My usecase is running a server locally so you can use a webapp with local network speed and offline access and lots of local storage.

<comment><USER10> Oh sure, there's all sorts of integration possibilities. Docker Applets, ActiveDocker, Docker Web Start... ;)

<comment><USER11> DockerScript™

</comment></comment></comment></comment><comment><USER12> I've noticed some pretty extreme performance penalties with Docker for Mac. Wherein VirtualBox would spin <60% CPU idling a bunch of services (MySQL, RabbitMQ, Redis, Elasticsearch, Memcached, several Python daemons) - <USER2> for Mac's driver hovers around 100% (spiking often to 200/300%) with another 20-30% (spiking to 50-80%) on the osxfs.

I'm going to guess it'll get better in time. It would be nice to get some insight into just what is burning CPU cycles. The experience besides that was really top notch IMO.

<comment><USER6> [I work on Docker for Mac]

The early betas focussed on feature completeness rather than performance for filesystem sharing. In particular, we have implemented a new "osxfs" that implements bidirectional translation between Linux and OSX filesystems, including inotify/FSEvents and uid/guid mapping between the host and the container. Getting the semantics right took a while, and all the recent betas have been steadily gaining in performance as we implement more optimisations in the data paths.

If you do spot any pathological "spinning cases" where a particular container operation appears to spiking the CPU more than it should be in, we'd like to know about it so we can fix it. Reproducible Dockerfiles on the Hub are particularly appreciated so that we can add them to the regression tests.

<comment><USER13> Previously I had permission issues (Only root can write to host) when mounted a folder with OSX filesystem. Hope this would fix those issues. I'm talking about this issue [https://github.com/boot2docker/boot2docker/issues/581](https://github.com/boot2docker/boot2docker/issues/581)

<comment><USER12> It does fix those issues.

</comment></comment></comment></comment><comment><USER14> Sounds promising. But I'd like to see Docker work with Microsoft to produce something even better for Windows, using the new Windows Subsystem for Linux (WSL). With WSL, Docker and Microsoft should be able to bring Linux-based Docker containers to Windows, _without_ the performance hit and resource fragmentation that inevitably come with virtualization. True, WSL doesn't support namespaces and cgroups, but IIUC, Windows itself has equivalent features. So the Docker daemon would run under Windows, and would use a native Windows API to create containers, each of which would use a separate WSL environment to run Linux binaries. I don't know how layered images would be supported; Microsoft might have to implement a union filesystem.

<comment><USER15> What is the use case though? What would be even better is if MS created a "windows container" that could run under Linux, then you could just ditch windows all together.

I don't see big companies using something this hackish for containers that are running on servers anyway. For working on the desktop this might come in handy for devs, but honestly I think MS should focus their energy on something else.

<comment><USER16> I would use it for development.

Running Linux on Windows without a VM would be a godsend. And no, Cygwin doesn't count.

<comment><USER17> It has been recently announced by Microsoft and Ubuntu and marketed as Ubuntu for Windows.

It's actually on a windows subsystem that can run linux ELF64 executables natively on windows:

[https://blogs.msdn.microsoft.com/wsl/2016/04/22/windows- subs...](https://blogs.msdn.microsoft.com/wsl/2016/04/22/windows-subsystem- for-linux-overview/)

</comment></comment></comment></comment><comment><USER18> Why do people value that so much? I really don't care if a tiny VMis running in the background. Also, running that VM gives me more confidence that it will also run on the production machine (since they use the same kernel and the same docker version).

The only problem I had with docker was that I did not use to support shared volumes that are outside the home folder on Mac (I think they changed that now, but I'm not sure).

<comment><USER19> Running a VM means you have to allocate X amount of RAM regardless if how much is actually needed by the containerized processes.

<comment><USER20> You're still running a VM with this, just via xhyve and the OSX Hypervisor framework, rather than via Virtualbox or VMWare.

Which actually makes me wonder how they're managing memory for the VM hosting Docker here. Are they specifying a set fixed allocation? Is memory usage configurable somewhere?

<comment><USER8> Not quite configurable yet, but it appears that's the intention. (I wouldn't be surprised if they'll try to make that a bit more dynamic, if the hypervisor framework allows it.)

</comment></comment></comment></comment><comment><USER21> I've been using the Mac Beta for a few weeks and I can also say it's great. Install is easy and it just works. It's such a relief being able to do dev work directly on my machine without docker-machine/VirtualBox. I've been hitting it with a variety of Ubuntu-based containers without any issues.

</comment><comment><USER22> I've been using the following docker-machine plugin and found it to be great: [https://github.com/zchee/docker-machine-driver- xhyve](https://github.com/zchee/docker-machine-driver-xhyve)

<comment><USER23> Author here. I was using that prior to getting in the beta. Tremendous work went into that driver, so I'm happy to see the techniques get picked up elsewhere.

</comment></comment><comment><USER24> The touted "native" is not what it is all cracked up to be. Maybe windows is a plus that brings a few souls into the fold, but I've been looking for OSX performance ratings and only found some comments here and there that are like my experience.

At my El Capitano, the exact same setup in Docker Beta takes roughly ten times to do its thing than my more flexible vbox setup did. A java stack (Jenkins) starts in about 1.5 minutes, but with Docker Beta it takes 15 minutes or about!

So, my docker-machine setup lets me see my hosts with vbox, manage them with docker-machine, and get the NFS tweaked with docker-machine-nfs. boot2docker OS is nice and small and works.

So for me this is quite a contrast with the 'native' Alpine images based Beta. Which in my 5-hour stint with it did not show much way to overview or inspect it without getting new/more gear.

</comment><comment><USER25> I have Docker for Windows Beta, but when I've installed it on my Surface Pro 3, it immediately caused the device to get stuck in a BSOD loop. I think it has something to do with Hyper-V and connnected standby but I'm not 100% sure. Wasn't able to find an answer because it's so early on. I really want to get into Docker, but that bug has killed any possibility of me adopting it as of right now. I did install it on a desktop (which I lightly use) and it worked fine. With the new Windows 10 Insider build on that desktop though, Docker constantly is asking permission to run.

Anyhow, I really hope someone does a good overview of Docker for Windows beta, as well as the Ubuntu environment within Windows 10 now...Seems like OSX gets all of the dev love, so I'm wish and hoping for a really nice Windows overview. As I am currently having a hard time with both. Neither, as of right now, work well.

<comment><USER26> if you want a more technical review of the Windows beta, read this: [http://docker-saigon.github.io/post/Docker-Beta/](http://docker- saigon.github.io/post/Docker-Beta/) But note that beta 8 was released a few days after that review and already introduced some changes. Also, for the Windows beta, it very much is still a beta.

</comment></comment><comment><USER27> I started playing around with Docker for Mac in an attempt to get my whole dev environment set up in Docker. It was really slick, especially being (re-)introduced to docker-compose which makes connecting containers very easy.

There is a ton of potential there. My biggest challenge is that the documentation hasn't quite caught up to all of the interesting stuff that is going on. I'd certainly welcome some more opinionated answers for how to develop on Docker. Specifically: how to not run apps as root, as almost all examples use root and permissions are annoying if you don't do so; how to use docker containers for both dev and prod; best practices for getting ssh key access into a container during the build phase.

But much of it Just Works at this point, I'm pretty confident that the best practices will catch up in time.

</comment><comment><USER28> I'm a node.js developer. I understand the benefit of using docker for deployments or CI testing, but I have yet to be convinced of the benefits of using it for development on my local machine.

I install node, postgres, and redis natively and it all works fine. What benefits does docker provide to my workflow?

<comment><USER29> You might need different node/postgres versions for different projects.

<comment><USER30> Or indeed for testing the same project against different versions or in different environments.

</comment></comment></comment><comment><USER31> For anyone wanting to use all this cool stuff without waiting for the release, check out nlf/dlite [https://github.com/nlf/dlite](https://github.com/nlf/dlite) which has the xhyve implementation already.

</comment><comment><USER32> Whoa! When did OS X add the The Hypervisor Framework? This looks really promising; I need to check this out.

<comment><USER33> I believe OS X 10.10 is the earliest availability.

<comment><USER32> Ah okay. One of my co-workers who worked at Apple told me:

      > It was a prerequisite for any VM stuff being sold in the App Store

</comment></comment></comment><comment><USER34> VMWare Fusion does a few extremely useful things that Docker doesn't - <USER3> instance it can hook into an existing Boot Camp install and load it as a VM. It may be a bit heavy for the (Linux) applications Docker excels at, but for me it's worth the money just for the Windows VM support.

</comment><comment><USER35> Anybody know if there is a full guide for the migration from toolbox to Mac beta? I've installed the beta, but I'm wondering if there's old cruft that I'll need to uninstall to be completely on the new.

</comment><comment><USER36> I signed up for the Beta, but I have not gotten access yet. I was hoping to see a walk through of an example on your review so I could gauge how easy it is compared to the old docker setup on osx.

</comment><comment><USER37> So if I'm using dlite now, and I want to transition to Docker for Mac once I get into the Beta...what do I need to do? Fully uninstall dlite? Can they be run side by side? (assuming no)

<comment><USER38> I am not sure if they conflict, there may be an issue with them both trying to use the same docker socket though, but you can probably just start one after you stop the other.

</comment></comment><comment><USER39> Good review. One thing mentioned is that the author was able to remove Kitematic amongst other things. Kitematic is a GUI for Docker. There is currently no replacement for it.

<comment><USER40> I was under the assumption that Kitematic wouldn't work with the beta but low and behold it does. I'm not sure what it will do if you have the old Docker toolbox installed at the same time however.

<comment><USER39> I had an older version of Docker installed as well as the beta, so when I installed Kitematic nothing worked correctly until I reverted everything.

</comment></comment></comment><comment><USER41> I got an impression that this is not that useful for development due to very weak networking support.

For example I use a single docker installation in a VM to test several unrelated projects with all of them providing a web server on a port 80/443\. I do not want to remap ports not to deviate from the production config. Instead I added several IP to the VM and exposed relevant containers on own IP addresses. Then for testing I use a custom /etc/hosts that overwrites production names with VM's IP addresses. This works very nicely.

But I do not see that something like this is possible with "Docker for Mac".

</comment><comment><USER42> My only issues so far have been: 1) the docker.local issue on mac (as a fee others have mentioned) and 2) I still get some vpn issues with Cisco Anyconnect

</comment><comment><USER43> Docker 4 Mac is awesome - however running into some issues with running `npm install`, with the container not completing I think due to CPU issues.

</comment><comment><USER44> The only downside of using virtualization I keep running into is diskspace usage, which only grows for the VM, and it never shrinks.

</comment><comment><USER45> The interesting bit here is that in this scenario Docker creates and runs an actual VM, not so much a "container"?

</comment><comment><USER46> So it uses xhyve...does this mean Docker runs up a full hypervisor per Docker process you run? That seems a bit excessive.

<comment><USER47> That's not the case - there's only one virtual machine shared by all containers.

<comment><USER46> Oh...that's interesting. That would even be useful on Linux to enable greater resource separation between processes...say being able to lock all Docker processes down to 1-2 cores on a machine and with a hard memory limit they can't exceed.

<comment><USER48> What you mention is a major reason why Linux containers were invented, and is already possible with Docker today. Take a look at the '\--mem-limit' or '\--cpu-shares' flags for 'docker run', for instance.

</comment></comment></comment></comment><comment><USER49> Anyone has had a chance to try the windows beta? Would be interested to read about that to. thanks in advance...

<comment><USER26> if you want a more technical review of the Windows beta, read this: [http://docker-saigon.github.io/post/Docker-Beta/](http://docker- saigon.github.io/post/Docker-Beta/) But note that beta 8 was released a few days after that review and already introduced some changes.

</comment></comment><comment><USER50> I don't get it. Why is Docker for Mac running Linux containers? Shouldn't it be for OSX containers?

<comment><USER51> Not really, unless you are going to be running OS X in your server. You want the container in your development machine to be as close to the one that'll run in production as possible to minimize "Works on my Machine" issues.

</comment></comment><comment><USER52> I think docker for Mac is the way to go but, until disk performance is not up to scratch, I suggest you have a look at dinghy ([https://github.com/codekitchen/dinghy](https://github.com/codekitchen/dinghy)) it just works too and it's 10x faster than docker-machine with vmware/virtualbox shares (uses NFS).

</comment><comment><USER53> Can anybody in HN provide a quickpath into the beta? I signed up when it was first announced (seems to be over 30 days ago: [https://news.ycombinator.com/item?id=11352389](https://news.ycombinator.com/item?id=11352389)) but haven't heard anything back yet.

I'm curious about the state of compatibility because I've drawn a line in the sand -- and refuse to upgrade from 10.9 (since many things seem to be getting only worse and less stable in MAC OS land :).

If it really worked (especially on Windows) Docker would post the binaries instead of treating this like Wonka Golden Tickets. Love Docker, am actually waiting to be approved so I can get to building something, but posts like this are a symptom of a larger problem.

<comment><USER54> Disclaimer: I work at Docker.

The reason we are keeping the beta private is because we don't believe the quality is good enough yet to "open the floodgates". We are sending as many invites as the engineers are comfortable with - currently that's several thousands per day. As we hit more and more edge cases (performance, stability, support for unusual configurations...) we are expanding the pool as fast as we can.

<comment><USER60> I appreciate this but in that case you should collect configuration data as part of requesting the bits. If I'm on a machine that's known borked, I'll wait. If not, gimme and I'll help you fix. Otherwise it feels like you're just using this as a marketing trick to build buzz.

Hipster bullshit that can't be used in any org that remotely takes care of their network (hint: any big corporation will mandate this by contracts with huge liability figures in the contracts).

To the users: if you can't configure a simple local web server for development, you should not be qualified to develop a web service. Period. (Hint: Apache and PHP is included in OS X, but a bit outdated to be fair - <USER4> you can install/upgrade to a OAMP stack using MacPorts in MINUTES)

And whenever a "newer, smarter company" disregards fundamental IT security practices and gets hacked, the sun shines a little brighter in my world.

Security is an afterthought (if a thought at all) in many hipster operations, and it's about time someone fucks up so badly that IT security is priority #1 from the beginning.
