Writing a toy ray tracer is something that I'd recommend to everyone who's interesting in becoming a better programmer. Once you get deep enough into it you'll encounter so many in…

I do. I've got the server counterpart set up on a Linode and sync my task lists across all devices. That's quite nifty because I usually think of things that I should be doing whil…

I came across this yesterday. Not necessarily just exploiting a Windows security hole though. http://media.ccc.de/browse/congress/2013/30C3_-_5476_-_en_-_...

The beauty about Linux (and a lot of well-maintained open source software) is that security flaws are usually patched rather quickly -- with the possible exception of the disaster …

Same here, although I somehow wanted it to win, so I could finally at least see the mythical 2048 tile that everyone seems to be speaking of.

I'm running dwb, version 2013.08.03 (either the maintainer for Fedora is slightly lazy or there hasn't been a new version in a while) on Fedora 20. It reports Safari 538 and OSX as…

Many NP-hard or NP-complete problems have (infinitely many) instances that are "easy" to solve. It is quite straight forward to write up a procedure that produces infinitely many i…

This might come across as quite harsh but the article could have been much shorter. NP is the class of decision problems that can be solved by a non-deterministic Turing machine in…

I thought the hash was in fact used for ensuring data integrity. That's pretty much what Linus stated when he said you have a guarantee that the data you put into your repository i…

I'm no expert but as far as I understand, the signature would be valid as long as the hash stays the same. If the commit has been tampered with in such a way that the hash does not…

I'd be interested in learning Rust. I've been learning Haskell last year and I'm absolutely loving it.

But, wasn't the drama exactly the point of the article?

No specific examples, but all of my best optimizations as in biggest-speedup were of algorithmic nature that actually improved asymptotic complexity. In terms of my favorite ones, …

There's a lot going on and that's the way it has been for quite a while now but as someone who's working with databases only marginally at the moment, I'm left wondering: What's wr…

I used to strive for clever solutions. The shorter the better. I still like to look at them but I want them as far away as possible from my code base. Sure, if a solution is clever…

That's really all there is to it, isn't it? I've never understood why some people feel the urge to modify the same variable multiple times in the same statement. It doesn't help re…

I know what you mean but it's early in the morning here and I feel like being a bit pedantic: As far as we can tell neither of the algorithms actually terminates for arbitrary inpu…

chas explained it very well already, I'd just like to add that this is called a "lambda function" (or lambda expression) or an anonymous function, just in case you want to look it …

I've already posted this on /r/haskell on reddit but since the article turned up here as well, I might just as well post this again. Since we're talking optimization I had a short …

> not a problem of the paradigm Correct. The main problem I see with OOP is that some people advocate it as the only correct way to write maintainable code, which, of course is com…

I keep in touch with mine just fine without Facebook. I use my phone every now and then for actual phone calls and sometimes even meet them. In short, I do what people have been do…

You can also add this line to .inputrc which will give you vim keybindings in everything that uses the readline library (for instance, ghci, ipython or gdb). However, I found that …

In fact I think everybody who's interested in the subject should try to roll their own crypto for the experience and fun in it. They shouldn't use it in the real world though.

Or the original Halo on the first Xbox. If I remember correctly that game alone promoted the console for a lot of customers. Valve could give HL3 a head start of a couple of months…

I haven't bought a Steam game either. In fact, I don't even have an account. For the past couple of years I've been locked into the MS ecosystem with the Xbox 360. I will not buy t…
