> "I really don't like if somebody by default compares Hadoop with SQL"

The first comparison was to Scala, and then to SQL. The main comparison was to SQL and a Python script. While it does talk more about SQL than other solutions, I don't see that as a default comparison.

> "For those, the in-memory, GPGPU, streams are much better"

I'll go off on a bit of philosophical tangent here. Yes, GPGPUs can be more effective for the task I'm doing, since I'm actually memory bound. However, GPGPUs require dedicated hardware, while the code I work is effective even on laptops with limited GPUs, including web servers.

Ideologically, I prefer to enable single-person developers, and scientists who do not have much training in hardware and network administration. For that situataion, GPGPUs are not "much better", because so long as the performance is fast enough, it doesn't need to be faster. And 100 ms is "fast enough."

> "This way you don't need to transfer a lot of data"

True. But to point out, I used the traditional approach of developing a file format which can be memory-mapped directly to my internal data structures, and a search algorithm which doesn't need to search the entire data set before loading it. These optimizations aren't synergistic with how I understand how Hadoop works.

> Hadoop's tragedy ... mostly driven by technologically clueless people

The author of the essay agrees with you. Here's the P.P.S.:

"I don’t intend to hate on Hadoop. I use Hadoop regularly for jobs I probably couldn’t easily handle with other tools. ... Hadoop is a fine tool, it makes certain tradeoffs to target certain specific use cases. The only point I’m pushing here is to think carefully rather than just running Hadoop on The Cloud in order to handle your 500mb of Big Data at an Enterprise Scale."

This is why I don't think you actually disagree with the author.

> Think about your case for chemical structures - is there any part of your algorithm that needs to be computed only occasionally but it's a lot of data to process?

Certainly, but there are two other important facets to that. 1) updates occur weekly, a full rebuild on a single core only takes 12 hours, and those 12 hours aren't critical, and 2) the deltas are relatively small and data from previous builds can be reused, so incremental updates should take about 30 minutes - I'll be working on that code in the next couple of weeks.

It's easier to have a cron job trigger a command-line program every week than to set up a Hadoop server.
Actually, Crockford is completely wrong in his definition. He is confusing them for functors.
I hope readers understand this 2007 prediction didn't happen, but that this doesn't count as evidence against global warming. It's a matter of which interval one chooses for a moving average -- short interval shows cooling, long interval shows warming.
Have you seen crazybump?

There is a good tutorial on it at http://www.blenderguru.com/videos/the-secrets-of-realistic-t...

It is a program that takes a single image and generates diffuse/normal/occlusion/specular/displacement textures from it in such a way as can be easily used as a material in blender.

As you can see from the video, it can work amazingly well given the limited amount of input information.
That's very interesting. In the US, if we only accepted 20% of people who wanted to be teachers, we'd have a very bad shortage of teachers.

The real questions is, why do so many people want to be teachers in Finland?

Well, OpenZFS is already vulnerable to it. So if Oracle will decide to sabotage it, it easily can.
I would imagine not. Not only is PG very influential at many of the companies these investors would want to invest in, but most of these investors are also going to be hesitant to out themselves as being a "contemptible subspecies of investor".
Machine language: How Siri found its voice
I noticed that too. Lots of the new apps have a distinctly "Android" feel to them, even to the point of Fancy having what looks clearly like an Android menu button (though not in the standard Android location).

A fun flame war to start (i.e. let's please not) would be to argue whether this is due to app designers feeling an increasing need to target Android or whether it's because the truth is that iOS's "new look" seems distinctly Jellybean-like to an app designer.
Agreed. Being from Chicago I think that its very natural for all the points listed above. The density of the city with the void of competition in the space (only Peapod comes to mind) make Chicago a great market to expand too. Chicago usually doesn't come to mind first as an early adopter market but given the rapid adoption of Uber (like other cities) I think the market is proving it is interested in similar services.
Yup, what happened with butter fs?? It was supposed to be better than zfs, wasn't it?
One thing I'm seeing on Hipmunk specifically is lower contrast and lack of shading has to be made up for by white space - the after seems to have a lot less information on screen, while still being (at least in my perspective) harder to read at a glance.
I consider myself rather forward-facing developer when it comes to design, and have, as a general rule, enjoyed the new interface design choices in iOS7. However, I'm worried that this Oddysean journey into "flat design" is counter-intuitive to some basic UI principles.

I find that the bottom toolbar is harder to read now, and requires more eye-scanning to figure out what the different icons do. It's not as pronounced and grounded anymore. Also, the top navigation is less intuitive, and more subtle. I'm also finding information and text presentation to suffer as well. As much as I hated the beveled edges and skeumorphic design of the previous iOS, it was much easier to navigate. I'm sure companies and designers will work some of these early-stage kinks out of the interfaces, but I can definitely see a drop UI flow quality and information presentation with the move to this new interface design.
Of course the non technical user is not generally the one complaining.
A neat feature but I wish they had support for 3d source file types instead of exported "binary", for lack of a better term, file types. If you wanted to truly open source your mechanical project you'd need to add an extra step to delete the previously exported STL and export a new one every time you commit. You also lose color/texture data when you export to STL.
I was thinking the opposite. Competition is good and there isn't any obvious competition to Google in the self-driving car space.

It's different because prior to this change, you could make an educated decision about whether to support an older version of your API based on usage of your app. When the legacy version reached some threshold percentage of your user base you could be fairly confident that you were inconveniencing a small and dwindling fraction of users and drop support.

With this change you can no longer be confident that app usage for legacy versions will always decrease. If your app suddenly becomes very popular (as most app developers are aiming for), you might have a substantial contingent of users who are on an old OS downloading an outdated version that you no longer support.
You're considering a field that favors a mature, experienced individual, and especially favors someone with a software background. So your plan seem perfectly sound, both for your age and for this time in history.
My thoughts exactly. A lot of these designs came down to putting lipstick on a pig. Yep, it's still a pig.

Like the abstract approach. But if you get 'wholesale pricing', the ticket is worth more to own, no? you'd then lose money on the sale. AFIK lottery tickets are only sold on comission, for this reason. If you could get the govt to sell you the tickets at a discount (lobbying.ribels), that would be an interesting investment fund, indeed.
Google will put a markup on licensing. If Tesla owns technology and produces it, they can a) have it free for their own cars, b) license it out and compete with Google's pricing. Tesla's model is so successful because they keep everything in-house, therefore there aren't tons of profit layers added onto production and distribution.
BEAST in practice, at least as far as I understand it (pretty well, that is, except that I might be dating myself a bit) requires more than a vulnerable browser. The attacker needs precise control over the first bytes of a new request on an existing SSL session. As I remember it, Thai and Juliano needed the Java plugin running to demonstrate it when they first discovered it.

As a blind person I get excited about this until I think of just how much the first models will cost. I guess I should save what would now be a car payment if I could drive in hopes that it will be enough of a down payment that I can afford one of these when they come out and pass all the regulatory hurdles.

The US criminal justice system is very much about punishment and retribution and almost not at all about rehabilitation or protection of society.

That's the sort of system one would expect in a medieval country, we can and should do better.
Perhaps, but overall it seems like bad strategy to avoid doing something because you're afraid it might help competitors. You do whatever you think is the best thing.

The whole point of a news aggregator is to make it easy to find and consume content. It's bad form to link to content that a large chunk of their audience can't easily read, and by "easily" I mean "click the link". I get that the NYT has some worthwhile content that doesn't exist elsewhere, but paywalled links on HN should be clearly marked at the very least.

There is actually a reasonable amount of competition within the autonomous car space. A lot of people online only ever hear about Google's initiatives, but Audi, BMW et al. are building driving systems, some of which approach 100+ km/h.[1]

I definitely agree that more competition in the area is good. Hopefully as more players build these systems, they'll continue to improve and be commercialized quicker.

My understanding (although I'm not certain) is that a license to use and modify the software also implicitly grants a license to use the patents contained in the original code.
Fascinating. The new designs seem to look very W8 Metro.

I confess an idle curiosity as to why the art style shift and if there's a genuine change in design philosophy (e.g., Modern vs. Romantic type watershed moments) or if it's just a flavor of the day shift (I can often date websites and books by their visual design elements, but it doesn't mean that there was a fundamental philosophy shift).
We did studies, but decided they didn't measure what was most important.
The only issue I recall is that the random-looking data involved in crypto confuses the conservative GC, so your app is unlikely to release memory in a timely fashion. More of a problem in the small address space of a 32-bit application.
I'm sure we have a country like Norway somewhere in the United States. Perhaps New Hampshire? Just like we have a country in these United States to match any small European country whose statistics are brought forward to push some kind of social agenda.
> Rent pays property tax, too. It's indirect, but it gets paid.

In California, due to Proposition 13, many many landlords pay 1970's level property taxes. It makes sense to rent these properties and split the savings with the landlord.
Actually, several manufacturers have self-driving car projects[1]. some of them are even field-testing them in real-life situations, such as a driven leader truck being followed by other trucks[2].

So, I don't think it lacks competition for Google, who doesn't even build their cars - most probably they'll license the technology for other companies, and Tesla may well be one of them.

The Atari Archives piece was part of what motivated me to ask about this. Another part is the series of books Jordan Mechner has released (in both print and electronically) about the development of Karateka and Prince of Persia. I've found that I enjoy following along the process of discovery almost as much as I enjoy the finished product. There is also a practical benefit: I gain more intellectual tools for tackling obstacles by learning the process others use to tackle obstacles.
Our political system sucks. I'm deeply affected by the US or Russian government's actions - because the Internet is mostly American and Russian, yet I don't have rights to influence decisions in either of those countries. Our country's minimum monthly wage is $211 and our average - $500, so there isn't even a lot of voting with our wallets that we can do. The only choice I had is to donate to Fight for the Future and plan moving everything to a home server, essentially reverting to my setup from 5 years ago.
Not to mention, what is the point where Google just has their fingers in too many places?

It's not. Only a small percentage of prisons are for profit (http://www.propublica.org/article/by-the-numbers-the-u.s.s-g...), and our tendency to incarcerate people dates back to long before we had for profit prisons. Our incarceration rate is mostly a backlash against desegregation. It's mostly because of the war on drugs, which is at its base a war on black people.

There are some who believe that iOS 7 represents a grand
reset of the app market, and a new land grab is afoot.

Personally I question that: Most users have no clue about iOS 7, and quite simply don't care. One day they'll get a system update notice, and from then forth every now and then apps will change incrementally. I don't see users changing apps just to get a new general style.

> If the CIA had noticed that event and the significance you attribute to it, when it happened, they still would only have gotten passing marks.

With all respect, you're assuming too much in hindsight. What Gorbachev was to do might not have been apparent even to Gorbachev in 1985.

> That they never noticed, is what leads one to wonder what the hell they were doing all those years.

You're assuming that the events were predictable in advance, by anyone. Obviously if the Politburo had been able to anticipate what Gorbachev would do, they would have had him killed instead of appointing him premier. On the basis that he won the post, no one had even the crudest foresight. Certainly not the CIA.

Looking forward to trying this out! Node is one of those things (well, probably Javascript in general) that I have learned through use but have never really followed a proper training path to understand it from the ground up. While I can't imagine that this is will be exactly that for me, it does seem like something that could help some of my (admittedly wide) gaps in knowledge about Node.JS.
Actually, Oracle was the company that started development on btrfs, and still does contribute, so using btrfs would also be supporting them in a way. I'd argue that developing for zfs is the way forward because the underlying license is less restrictive than the GPL, and can be used in more Free and Open operating systems, making it easier to use the best kernel for the task at hand.
I imagine I might agree with you on many things -- there is much to be admired in this Norwegian system and an there is much to be lamented in the US system. However you lose me when you say 'perceived transgressions'. The transgressions are real -- you might think that certain drug laws are injust (I certainly do) but the transgression is not simply perceived. And certainly I'll grant you that people have been wrongly convicted -- but that is a very small part of the prison population.

That being said, our prisons aim to punish, incapacitate and rehabilitate. Punishment is a legitimate role for society; it is not juvenile.
For those who love the food when it's served fresh, I wonder how the experience holds up to shipping. The Philly Cheesesteak from Campo's Deli, for example, is flash frozen and shipped to you on dry ice. That's gotta do a number on the taste and texture. At $95 for two sandwiches (that would cost $16 for both at Campo's), that's a bit too much of a leap of faith for me.

Getting the best cheesesteak sandwich in my city might only be an 8/10 compared to a 10/10 one from Campo's Deli, but a frozen and then reheated Campo's Deli cheesesteak might only be 8/10 compared to its fresh version. And ordering fresh local is not only way more convenient and cheaper, but significantly more environmentally friendly. I could pay someone $60/hour to fetch a couple of the best local cheesesteak sandwiches, reimburse them for the food, and still come out ahead with fresh sandwiches when I want them, not two days later.

It's an interesting concept and obviously people are willing to pay for the luxury, convenience, and getting authentic food. I suppose I'm not one of them.
I can't be the only person to think that iOS 7 does not look good. Right? A lot of the "after" screenshots do not look any better. I'd say some of the after screenshots look worse!
How? In some cases they added new information to the screen, but that has nothing to do with the iOS 7 motif. Otherwise, the "information" is generally obscured and no longer distinguished from controls.
I'm confused. If you're saying that Finns do well in school even though nobody forces them to, then they would seem to fit the definition of excellent students to a tee.
