Does that mean by the time Google had decided to work on the iPhone-like Android interface, they had been planning to work on a turn-by-turn navigation system using Google Maps for Android as well?
Well, if you're right, and this is all the work of an internet troll who doesn't actually possess any documents, then those documents won't be released. But if they are released, will you be willing to admit you may have misread the situation?
Patently false.

Skype was supporting tens of millions of concurrent active users on a sharded PostgreSQL setup years ago (like, 2006-07 or so). Yes, the support wasn't native, and they had to write PgBouncer and PL/Proxy to enable that kind of scalability, but they Open Sourced both projects, and they're pretty widely used in many environments for exactly that purpose.

As far as JSON, the HStore extension has been available some time since 8.3, which was released in 2008. Again, not native (though that's being addressed with 9.2, which should drop any time now), but not particularly difficult to use. A trivial web search shows people using JSON with HStore at least as far back as 2010, if not earlier.
Ungraciously it could be argued that atlassian's tools fall in the time waster category as well.

The amazing thing about T.O. is that the cost of living is a lot less so in practice you will have a lot more disposable income here in Canada.
Yes, 250mb/month. Not exactly an incredible announcement, if you ask me.
No, I don't think so, not in its current state.
Maybe you could help us understand what the Raspberry Pi isn't addressing for you? I run debian on mine, can SSH into it easily over ethernet, am running a webserver on it, and could put external storage on it should I want. And it only cost me $35!

Edit: I should point out that I'm doing all of this from my backpack, and that this was incredibly straightforward to set up with off the shelf parts. Honestly, it feels more or less like any other debian system I've worked with.
I agree with you that for practical hiring purposes the supply of people with a credential available for hire is significantly smaller than the supply of people with the credential. From the perspective of somebody who is not in this in-group and wants to get hired, I would use the broadest possible reading of who holds these credentials (n.b. I really don't think I'm wrong about 200k) and the narrowest possible reading of people capable of substituting for my labor ("me").
Good point. My plan is to take open data from things like Wiktionary and Wikipedia and dynamically generate up-to-date cards from them.
Keep in mind that even at Fortune 500 companies, budgets are limited to the department, and within that department, the presumed impact of said project.

Every time I have negotiated with a company of this type, I have come away thinking that they had unrealistic pricing expectations. That said, you must price higher because of the bureaucracy you will be dealing with.
> No app of significant size will actually allow this.

Never heard of ORM ? In the Java world it is very, very common to have database independence.

And most enterprise deployments (i.e. significant size) are Java.

Note the phrasing "142 startups... submitted over $30m in job offers." Sounds like if company A bids $200K for SuperNerd, and company B bids $250K for SuperNerd, they'd count that as $450K of submitted bids. SuperNerd may have declined both offers, so income might be zero. See the "Vanity Metrics" section of this article (but ignore its title):

I totally agree the SR&ED is a huge plus for canadian companies. I've co-founded or been part of many successful startups in Canada and they were in part successful because of the SR&ED program. As long as you design and/or develop algorithms and software/hardware that improve canadian R&D you qualify for the service. $100k spent on the first year will give ~ $60K the next year, which you re-invest in R&D, and that gives you $36k the next (e.g. you double your origin $100k investment in two years), etc...

There's also the IRAP program from NRC which can be good. I've used it quite a few times for small projects. If you qualify for the program, IRAP will match your companies contributions up to a dollar amount, for the approved project.

I think you're seriously missing the point. The point is not "employees for company X are all awesome!", but rather "company X is a good filter". This is no different than saying "a CS degree is a good filter"; it's not the be-all end-all, but it's a nice initial filter.

(Note: I have neither a CS degree (or even a high school diploma) nor have I worked for any of the companies mentioned.)
Not false.

Skype added sharding support themselves. And it requires you to use stored procedures instead of SQL making it unusable for most users.

And I am talking about native JSON support as a first class citizen. Nobody is going to lock their entire data structure to a third party extension that may or may not disappear.
It's true, it is kind of a PITA. Users of our VLA observation preparation tool can nest scans inside scan loops, and this is represented in the database with the self-referencing PK. In the tool we never really need to do the nasty recursive select, but occasionally I need to do them to do reports, and it's never a great joy.

That said, I'm glad I have the power, and I wouldn't throw away Postgres and switch to something else just because something else might store hierarchies more naturally. Postgres is not the perfect tool for every use case, but having hierarchical data by itself isn't enough reason to throw it away.
Abstract/linear algebra. I enjoyed it thoroughly at university but it never seemed very useful in practice, until I had to deal with a complex problem of manipulating graphs. All of a sudden I found semi-ring homomorphisms coming in handy again, and on the back of that realisation have made some very cool software.

The risky learning curve came when I had to revise all the stuff I'd half-forgotten, taking a few weeks out to do nothing but maths, in the hope that my hunch would pan out. It did pan out, and now I'm settling down to the long hard slog of exploiting it properly.

That $30 million figure is useless. It tells us nothing. Why was it included?

I think "culture fit" is just another way of saying "if we like you or not." It doesn't really matter how good you are, if you don't laugh at their jokes, or they don't like the way you dress, or if they think you might be a threat to their intelligence, you might as well be completely unqualified, because you're not going to "fit." Do I sound jaded? :)
This seems to say that it is a vulnerability with the Accelerated Log-in feature. I used to run Windows on my thinkpad and I tried that out for a few minutes but it seemed like bad news. You swipe your finger at boot time to unlock the BIOS and it automatically logs into windows after windows loads. I knew it was doing something that was likely to be bad and turned it off.

Jeff Bezos stated this explicitly during the presentation - Amazon wants to make money when you use the device, not when you buy it. So they sell the Kindles at a very aggressive price in order to get you into the Amazon ecosystem. If you're already there, they're not going to make much, if anything, if you upgrade.

Wow... Zynga... really? Because Zynga only takes the best of the best. I mean, not everyone can write trivial web versions of existing games and claim it as their own, right? It must be extremely challenging from a technical perspective. Only javascript gurus need apply!

Bleh, what a joke. If you don't have the first clue as to how to judge a technical candidate then don't bother launching your site. For every cut-rate javascript monkey you include here there are thousands of highly skilled engineers (yes, "engineers", not front end web-app developers) who you are ignoring.

The most brilliant engineer I have ever had the pleasure to work with wouldn't meet any of your criteria. He currently spends his days writing control systems for very expensive satellites (doesn't compare to FarmVille, I know). No, no glorious github profile, he chooses to do something other than programming with most of his spare time (ridiculous, I know). No, he didn't attend a prestigious ivy league college (where does he get off?), but I'll tell you what; I would put money on the fact that he is in the upper echelon of software engineers.

I'm not saying that there aren't highly intelligent people working at Zynga, I honestly have no idea, but it certainly doesn't seem like ground breaking stuff. Again, until you figure out how to judge applicants appropriately, do everyone a favor and shut down.

Is there some rule that says you must use a regex to validate an email? Just validate it with a more complex parser.

Alternate option: Validate it with a simple regex. If it fails ask the user "Are you sure this email is correct?" If they say yes, then allow it even if it fails validation.
If you have self-referencing rows, you're going to wind up with two options: an inefficient recursive query or inefficiently issuing N+1 queries. The recursive query would wind up being faster simply because there's a lot less overhead. That said, I don't know what additional optimizations or penalties are going on in the system, but I have never converted a situation from N+1 queries into a recursive query and found a performance degradation.

Of course other options should always be considered. Joe Celko has a book on storing trees in the database I've been meaning to pick up.
It doesn't seem that useless to me. Sure a better, less hyperbolic measure would've been saying there were x number of offers given, but assuming ~$100K salaries, that means there were about 300 job offers given out for 88 engineers.
"What system would encourage the most able technocrats, instead of the most ruthless?"

In general, I think in the US, we torture politicians and bureaucrats far too much.

However, I don't think putting smart people in government is going to solve all of our problems, and it could make things much worse (I'm serious when I say that -- sometimes smart people make extremely unwise policy decisions).

I think, what we really need, are people that:

* Have not publicly stated a bunch of opinions. The more clearly you state an opinion in public, the more it becomes a part of your identity no matter how ridiculous.

* Have been wrong enough times that they aren't afraid of being wrong one more time. They expect a high likelihood of being wrong, so build safeguards into their policies for when they don't work.

* Are willing to cede power. Maybe some federal laws could be state laws, instead? Or maybe state laws could be local laws? Or maybe they don't need to be laws at all, and the goal can be accomplished in some less-forceful way.
Neat concept, but the exclusivity douched it up bad and I'd short-sell it because of that. In the age of the Internet, you have to find a way to create exclusivity that isn't elitist. Hacker News is an exclusive community (the people we don't want here find technology boring) but not elitist.

By the way, I think you should limit your field to people who would never work for Zynga, not people who currently work there.
Apple has not "nearly matched" google, not at all. Maybe in the US they have, but in New Zealand, where google is as good as any of the local street maps/directories, if not better normally, the new ios maps is atrocious. The places are now even worse too, because they're relying on Yelp, who don't have a presence here at all.
This looks well done. I have a project coming up where the LED app board would be ideal, but I confess to a bit of environment fatigue. Arduino, beaglebones, raspberry pi… but the ease of app board construction intrigues.

I wonder if there will be CAD jockeys I can find to turn my design into production ready files. Someone up to speed on the tools can probably save me a lot of pain over learning them myself.

Good stuff. Another article on the same topic: http://www.job-buddy.com/advice/view/ahBzfmpvYi1idWRkeTItaHJ...
If the company culture is to listen to techno and drink beer, then sure. For that company you wouldn't be a culture fit if everybody else is going to bother you by doing these things. More important parts of culture could be, say, a reverence of quality, or being nice to people. If a candidate is an asshole, that would fly at some companies, and not at others.

It's not discrimination because one could choose to not be an asshole, or to develop an appreciation for techno. Discrimination is when you don't hire somebody because they were born differently than you, not because you don't get along.

You could try to spin not hiring people who like techno as discrimination, saying they were born not liking techno. You might be able to bend the definition to fit, but I doubt we'll ever see legal protection for people who don't like techno.
Isn't the point that the job offers amounts are supposed to go up for good developers because of the auction format? Don't necessarily blame developerauction.

I agree with your first paragraph. Science is based on consensus. You have to convince your peers you are "right". But what makes science worthy of being taken seriously is that it follows a defined procedural method of doing the convincing; and most everyone involved in science accepts that general method as being a sound one. People can actually agree on things because we all follow the same general method of arriving at conclusions. And... this works across a variety of disciplines.

Does maths use the scientific method to answer questions? Do the questions maths can answer concern areas outside of just maths? Is maths something that is used _within_ the scientific method to answer questions, in a variety of different disciplines?

It's a lot easier to approach and attempt to answer questions (get consensus) when you have a generally accepted method for doing so. It seems like maths entusiasists, e.g. the kind who love computers, can take widely different approaches to answering the types of wide-ranging questions addressed in the sciences. They may even disregard the scientific method altogether.

If Usenet/WWW is any indication I'm guessing this leads to a lot of disagreement between maths devotees if the topic at hand is anything but pure maths and logic.

Not taking anything away from people who love maths. In fact, one of the major problems in the sciences is the lack of mathematical rigor by far too many scientists when analysing results.

tl;dr Scientific method + maths = good. Need both for solid analysis and reasoning.

My reading was that the choice was more or less arbitrary in order to get a sufficiently small set to use as a test/proof of concept.

Having no knowledge of the founders at all, I would guess that some of the founders graduated from those universities and either worked at or know people who worked at those companies, and so they chose that list to start with because they were familiar with the range of quality they could expect of programmers from those places.

The second sentence in the quote outright tells you that they plan to expand this list. Presumably they could be convinced to advance their expansion schedule if there was a lot of demand from people not fitting their stated starter profile.

Basically, I think commenters here are making a big deal about something that's really just a temporary filter to reduce the volume of applicants until the company is ready to scale up. Maybe I'm being too trusting, but I didn't read anything sinister into it.
It's adverse selection: the type of people who would use this service are probably not the people you want working for your startup. The really successful people would be picked off in other ways (not actively recruiting) so you are left with the B and C players (which ironically are a dime a dozen)
The final OS is one thing (hold back whatever you want there), but where is the SDK? Developers need that if you want them to be ready (and you can always put your super-secret magic in the first post-launch SDK update). To me, the MIA SDK is the troubling sign.
Who cares. Just build your startup wherever you WANT to be and I guarantee that you will have a better result than trying to do it somewhere you don't want to be.

If you want to be in Canada then do it in Canada. If you want to be in NY or SF or Idaho or Mexico then go do it there.

That last point is completely wrong. Zynga is a lot more than the flash games you see on the front end, at least from a technical standpoint. Even with your obvious bias, you have to admit that they operate at a huge scale and that alone must pose some interesting technical problems.

A lot of the things the site does well would also work well for legal transcripts:

- Ability to comment on individual remarks

- Links to wikipedia articles for jargon

- Links to their own glossary

- Links to the original hansard source

- Mug shots of speakers: I found following the original Oracle/Google Groklaw transcripts more immersive after seeing at pictures of Van Nest et al.

- API access[0]

And I'm sure there are many others. Anyhow, I'm still glad Groklaw provides this service. For anyone who goes on about the apparent bias of the editorials on Groklaw, at least they provide the straight facts too. Then you can make up your own mind, rather than having to rely on other (potentially biased) journalists.

I'd anticipate that OSM will get machine vision in the future. Consider that that a typical phone/tablet now has a GPS, camera and decent computing resources. It's begging for a machine vision application, which records video and automatically extracts mapping information, ready for uploading to OSM. Begging to the point, where I think it's just a matter of time.

As an aside, are there any efforts afoot to decentralise OSM? It seems well suited to a geographically distributed database, with each country/area looking after it's own map, and the whole being drawn together by a common markup language. Assembling a global map would be a matter of crawling a network of servers, rather than downloading from a single source.
Perhaps I was a bit harsh (I don't feel bad), but I don't think I'm missing the point. They are attempting to create an artificial scarcity that promotes their idea of what a good dev is. It is elitist.
So what's the current average pay for someone that gets an offer using this auction? Any stats?
If these were elite software engineers and the compensation was $100,000 per year, then either (a) the auction did not work, or (b) that is a fair market value for engineers (which would mean that the auction worked, but the raison d'etre for it is suspect).

Engineering comp. is a long discussion, but I don't think the best engineers are under-compensated so much as under-utilized. Companies pay appropriate to the work people are doing, but staff engineers 3-5 years below what they're usually capable of.
