Actually, we started out using mongo to focus on the analysis instead of the schema, but we quickly ran into performance issues as the datasets grew. We were simply using mongoengine for Python, so we didn't spend a significant amount of time trying to optimize our schema or implement things like sharding.

Our performance issues with mongo largely stemmed from our poor use of indexes - we defined a lot of indexes because how we needed to query was a very organic and undefined process as we got new analysis requirements. Because we would have to frequently go back and compute new feature vectors across the whole (or large parts of) the dataset, we weren't able to implement a lot of the aggregation capabilities you'll see implemented in many other time series schemas.
You mean other than continue taking more money until an acqui-hire happens?
I don't think I would take that strident battle-against-dinosaurs view, in part because I think intellectually understanding things is useful in and of itself, not some kind of "just build it and shut up" anti-intellectual view; and also because I don't think it's an accurate summary of the history of AI. There's no particular reason we can't both build and study things in various ways, and the history of AI has been full of people doing many takes on both.

In particular, statistical approaches have been used for a long time, but were not practical until fairly recently; it was the lack of "big data" computing power holding them back more than anything. Statistical machine translation and parsing experiments have been tried on and off for decades, but with 1950s-era data they produced total garbage as output, even worse than the (also bad) symbolic approaches. Hence why Shannon's work on text processing didn't produce practical NLP or NLG systems. It took Google-sized data to produce statistical translation that was actually usable.

What numerical approaches were possible on computers of the time were fairly extensively investigated when they became possible (e.g. the 1980s focus on "sub-symbolic AI", with perceptrons, neural networks, numerical regression methods, etc.). Some were shelved for years because they just didn't work as well, e.g. symbolic game-tree search massively outperformed machine learning in board games in the early experiments, which is why Samuels's 1950s ML-based checkers player was theoretically intriguing but not considered very practical.
Well, given they're both in general Apple bloggers I'd be surprised if you weren't into Apple products you'd enjoy them. Kind of like I'm not into boats and find boat blogs really uninteresting.

Agreed.

I also follow Blender 3d; they regularly make short movies to drive various areas of development. Since they started that, the quality and ease of use went way up, and it's more ready for real studios.

I hope Meteor makes some awesome examples/tests at least.
But there is a difference between "quite hard" and uneffected by sudden losses of power. It is easy to make it the later, and then suddenly the "extra safety" is simply unfounded paranoia.

The bots do make mistakes, however, if they encounter a new circumstance their programming cannot account for. ClueBot NG, the anti-vandalism bot, has a small rate of false positives - edits it mistakes for vandalism, but which are in fact legitimate.

Since Wikipedia closely tracks edits, however, mistakes can be repaired almost as quickly as they happened, administrators say.

I think fairly consistent commentary over the years demonstrates that this is patently false. Deletionists are capricious and arbitrary, reversals are beauracratic, complex and lengthy (if even possible) It dissapoints me to think about how much legitimate human knowledge has been wiped from WP, the authors discouraged and WP made poorer for it.

What worked for me was to constantly look at designs in templatemonster and try to write down the reasons they looked good; then I would try to create one design using those ideas. Of course, I also read a lot of Photoshop tutorials.
It's a little bit frustrating to read a rehash of an argument that was cutting edge maybe back in the late 90s, especially one that is so poorly written, and framed as a battle between two intellectuals.

Chomsky's past his heyday. He has been seminal in his field, but he's no longer doing research which pushes at the boundaries of our understanding of language, how to model it, or what the fundamental nature of language understanding systems is. (as one might infer, I come from a non-chomskyian school of linguistics).

Given that we have actual data and research about large scale systems that do interesting things (including the massive artificial neural network that google built last month, see: http://www.wired.com/wiredscience/2012/06/google-x-neural-ne... ) reporting as substance free and obfuscating as this is, is a real frustration, when we could be talking about more interesting things, such as what a solid operational definition of meaning is, or how exactly heuristic/rule based systems actually differ from statistical mechanism, and whether or not all heuristic systems can (or should) be modeled with statistical systems.

The framing of this article is particularly galling because there are so many non-chomskian linguists out in the world who operate fruitfully in the statistical domain. Propping Chomsky up as somehow representative of all linguists is pretty specious and a bit irritating.
He's said on podcasts he's not a fan of Hacker News comments, so I'm going to say he's not overly fussed on hitting the top of HN in general.

I'm not sure what you mean by "faster," (what are you comparing to exactly?), but I think something that speeds up human learning considerably as compared to computers is feedback. Children don't just blankly sit there taking in information and then "fitting it" to a model-- they perform actions and observe the consequences; it is empirical. The embodied action-perception loop is fundamental to how real-world learning works. A closer computer model is reinforcement learning, for example, which does exactly this, it wraps a neural network in an action-perception loop an uses online training to learn the reward function. The problem is of course that the reward function can be very hard to design except for fairly simple tasks.

Again, disingenuous. CL has the network effect. That's like Microsoft saying, Users are free to install their own browsers. Their current actions are only to preserve that, not to squash abuses. (Which is what they usually do with the power of their TOU.)
That's precisely how Meteor auth works. Each client can request a set of documents from the server -- think of it as a predefined query. For each of those requests, your server code decides what (if anything) to send back to the client.
Intellectually, there seems to be something as wrong with avoiding anthropomorphism when discussing human endeavors (such as language) as there is with anthropomorphic explanations of erosion or chemical reactions. Skinnarian approaches to language may leave people unsatisfied because there is no story, just clinical observation.

Norvig's approach (as characterized in the article) takes the the "Artificial" in "Artificial Intelligence" to include the mechanism by which an intelligence makes decisions. Chompsky's aesthetic of linguistics applied to AI would treat "Artificial" as a description of the platform in which an intelligence is embodied (i.e. non-biological) while requiring the platform to operate linguistically on the same principles as a "natural intelligence."

Norvig's approach (as characterized in the article) is essentially a better Eliza (or Ford's faster horse).

If one takes the Turing Test as scientifically meaningful rather than an engineering standard, then one falls in one camp or the other and the Norvig Chompsky debate is over a pseudo-problem. "Artificial Intelligence" is in that sense metaphysical jargon.
This reminds me of the codeless code - obviously fictional stories, but written in such a way to make commentary on design patterns and practices in software development. They make for a very entertaining read, and are excellent at driving the point home.

>Sadly, he's utterly vapid and agenda-driven when talking about Android and Google

A big part of the element not being discussed is money. Less people who use Apple products probably means less page views for Daring Fireball. I don't think it was a coincidence that the focus of his enmity has turned from MS to Google since Android became a threat to Apple's most financially successful products.

The same goes for Marco. I expect him to have a bias towards Apple and developers because he makes his money off of Instapaper for iOS and he is a developer.

Gruber is a very talented writer but we all can be colored by how we get our paychecks. I will say that he amuses me which is rare among the blogging cynics.

There's nothing banning 3G access, just the ability to use your phone as personal hotspot. Kinda pointless banning it if 3G isn't available in the first place.
why? women suck at programming compared to guys. that's the truth, live with it.

listen, blame companies for all you might, but a good proof would be this, how many women have their own open source projects? they can do this for free, on their own time, with their own motive, no money incentives, from home, no discriminations, how many are there?
I can't remember if it's explicitly on the roadmap, but it's something I do plan on adding.
A significant proportion of the "academic approach" is actually a third one: artificial intelligence is the analysis and implementation of rational decision-making. That approach tends to care neither about biological accuracy, nor believability in a Turing-test sense. Rather, it cares about whether its decisions are correct based on evidence available to the decision-maker. That's the kind of attitude you most often find in both statistical and logic-based AI circles.

Actually, Russell & Norvig's AI textbook has a nice summary of these different approaches to AI in its intro chapter.

This is rather a broad brush, and a gross oversimplification of a complex debate that's been going on for a long time.
First Github, then Meteor. As Peter Levine pointed out in his blog (http://peter.a16z.com/2012/07/25/meteor-magic/) Andreessen Horowitz is making strides towards "help[ing] developers build the next generation of applications."

Are there any other VC firms that have had such a stong foothold on the foundation of application development?

Do games consoles not implement some kind of transactional system for game saves anyway? It would seem very harsh to lose all progress in a game because of a power cut! Especially since modern games don't seem to have any way to allow the player to make multiple arbitrary save files as backups.

That is actually Jon's point. The API by default is not transactional, while it should be. That is left up to the developer to implement.

> The icon for game saves actually kinda makes sense in another way.

Sure, it may make sense, but that is not part of cert. The message is required to show at any point where any data is being saved, which could just in fact be useless stats. In which case its possible to see the icon finish, shut off the game, and then later be suprised when the game did not in fact save your progress.
I've long thought that the spiritual difference between RoR and ASP.NET is that one is built by application developers, and the other is built by language and framework developers.
not working here either. the support forums are filled with complains :(
Simple really - productivity. On every shift you lose time starting up and getting everyone to work. This happens twice a shift (start of shift, coming back after lunch). There is a gap in time from when everyone clocks in to when they actually start producing. This time is referred to as "stand-up" and is when the manager covers safety, quality, admin messages, announcements, etc and also performs stretches. Multiply the time spent doing this by the number of minutes your shift is producing absolutely zero and you start each shift in the hole. You also lose some towards the end of a shift (everyone stops just a bit early until you start dropping the hammer). Knowing this, the fewer the shifts, the less "lost" productivity.
I think statistical models are an 80% solution. They get a long way down the path very quickly, but then they hit a wall and don't advance much further. Search, translation, probably also autonomous vehicles. They get to a point with statistical approaches and then they stop advancing.

The rapid success at first may be leading to a dead end.

Having said that, there's a lot of value in these technologies as assistance to human intelligence, but I'm skeptical they're ever going to lead to full-on autonomous intelligence.

This is a popular summary of Chomsky's thesis that was put down decades ago, when cognitive psychology was at its infancy. Now we know a lot more on how babies learn the world and language (do a Google search on "infant statistical learning") and most evidence points to the fact that they employ algorithms that are mainly statistical in nature for learning.

"Children learn language much faster than it seems possible for a "blank" neural network to learn." This is a very strong statement that has no mathematical or computational proof AFAIK. It had no proof when Chomksy first put down that thesis either, it was an axiom of his. BTW, belief in a specialized language faculty was not universal, even in the past, esp. some philosophers of language disagreed with this view.
