I hate to go against the grain, but I would say don't learn version control until you know you have to. The first time you get burned, like just lost a week of work burned, you'll know exactly why version control exists and why you need it.

I've used this before, and I highly recommend using fcgi instead. Modwsgi (at least when I tried it) was less stable and not as performant.

I get that timing attacks are reproducible in test environments and in a theoretical sense, but have any major real-life attacks been based on a timing vulnerability? Most websites anyone would want to attack will be running off of multiple

So what are the numbers for selects while writes are happening? It's really suspicious to show 'selects with no writers.' In terms of transparency, it's nice to have benchmarks that don't show you winning everything (makes me trust that you

I'd suggest an iPod touch + apple developer membership. J2ME is horrible to write code in, especially compared to cocoa or android java.

It's a standard ml technique that's been shown to work well, although no ones shown a proof of this. This is related to the observation "more data beats better models." This does seem to have it's limits - at some point you do need better

I really like scala a lot - it's a joy to write fast, succinct code with just a pinch of magic, but I have to strongly agree with all but the first critique. Scala has the underpinnings of an absolutely incredible language (fast, expressive

Check out en.wikipedia.org/wiki/Junction_tree_algorithm not a great article, but the referenced literature is ok Don't have much time to elaborate at the moment, but look up the "junction tree algorithm"- it's a way of performing inference

Although it sounds kind of cool, I'd be a little nervous trusting people working on commission for advice on whether a shirt looks good on me or not. It seems like it wouldn't be hard to have some sort of follow-up survey to unlock the comm

I don't know if anyone else has ever noticed this, but lots of street view pictures will have random face shaped blurs on walls and such. My guess is google has set a very low false-negative threshold for face identification, and are thus w

Oh man, if this doesn't have a keyboard on it I'm so getting one. The first two frustrated me so much - why not just give me a bigger screen? Question for anyone who has a kindle - how often do you use the keyboard?

Two huge reasons keeping developers on the iPhone - (1) Ease of development - cocoa + objc isn't very hard, and often is quite fun. Its roots in smalltalk help in the appeal to ruby/rails people, and, let's face it, cocoa apps are just plai

He says later that youtube is big enough that they've maxed out their economies of scale (hence costs won't come down, which seems like a reasonable argument). The real flaws with this article are that user content is growing geometrically

I think you need to tone down the pre-college stuff. Looking at your resume, it's not really clear what you've accomplished in the past couple of years versus what you did in high school. It's cool you did all that stuff, but none of it rea

This is possibly the lamest idea I've ever seen. Why would I give someone else credits? The only point is to trade them in for gifts, so I might as well just spend the points to buy gifts directly. Or, even better, just buy real gifts in th

Has anyone else noticed that you can't ping onlive.com? I wonder if they don't want people to see what the latency is to their server.

Running these two commands in series is likely vastly overstating the performance gains - almost all your time is going to be spent in io, and the second time around you'll have a good chunk (if not all) of it in disk cache. Try running bot

Yeah, but the whole point is you don't have a fixed length record. And in the example given you shouldn't be using strings at all - integers will suffice - that's the real problem with this benchmark. You might as well be testing how quickl

I think the schema is causing this. Lists of strings of nonfixed size aren't going to yield good results, as any serialization framework now has to perform work to find the delimeters of each string. In this case you could store IP addrs an

I think access to capital is the first step, but access to employees is what would present the larger challenge. Sure, you could get a hundred or so new grads from your university every year, but how many hackers migrate to the bay every ye

Easiest answer: If you're using neural nets (his example), you could just write the backprop algorithm. Chances are performance matters, so you can hand tune your code to generate the best assembly. Most of machine learning work involves hu

The whole bill of rights thing seems a little bit unbelievable - until they have a viable long-term business model, there is absolutely no guarantee that any of this couldn't change. They're not going to lock themselves in to their current

ehh, this is just (questionable) formatting. After you use python for a while, the __methods__ should become pretty common-sensical (and seeing the actual __name__ is more useful if you're trying to reimplement protocols common objects supp

Why don't they just use v8, tracemonkey, or squirrelfish? It's nice they continue to develop their own technologies (opera is awfully nice on cell phones), but, in this case, writing a js engine is a problem with lot's of pre-existing high-

This is partly based on stuff said in the BB thread: Wal-mart might treat it's employees better, but it's cut-throat treatment of suppliers forces them to cut their (the suppliers') employee treatment to the bone. When walmart might jump sh

You might not want to have your e.g. (iphone) return no results. Makes it obvious you have very little content (which makes me very confused what your site does).

Problem - 1 false negative or 1 false positive isn't usually a problem. Generally, if you have this many interviews you have some sort of voting system. Let's say it's consensus - then 1 false negative will disqualify some good people, but
