Re: Gategory theory for noobs !

There's also the appropriately named Basic Category Theory for Computer Scientists, by Benjamin Pierce.

and woah, those lectures seem good, though I wish I had heard them at the start of my honours year, rather than just after it had finished :p

You know, if one said AHAHAH and the other HAHAHA, i reckon it'd give them their own identities :)
But otherwise, awesome Mobius strip

Re: Best language to learn for programming contests

Definitely, if you can, C++ is a plus - if you don't mind the debugging, you can get away with a lot more in C++. The library thing isn't too much of an issue, both have their good and bad parts, though for ACM I'd recommend: whatever you team can get familiar with the fastest. You really don't want...

Re: PHP application into an exe?

I haven't read all that much about it, so it may be a very stupid idea, but it *might* just be possible to do this by writing the php site for use with Google Gears.
Basically, you can write your website to use a local SQLite database and just run it in offline mode the whole time.

Re: 1337: Part 2 Discussion

If Mrs. Roberts is the 2nd greatest hacker, why does H. Elaine Roberts have to train under Knuth? Couldn't she be home-schooled? I think you'll find that it's (the now grown-up) Elaine Roberts who is the #2 hacker. Any chances she'll ending up going to Redmond to Kill Bill? Edit: and while A* might...

Three things: 1. That's an amazing drawing of Jimmy Page. Almost...only thing missing is the two-neck guitar for Stairway I don't think it's a case of better music in previous generations, just more music in this one because it's so much easier to make, and because it's easier to remember current b...

Re: Help: strange gcc error that changes with optimization level

I think it's similar to what is already posted, but: C++ doubles are usually 64-bit. However, for intermediate calculations it can use an 80-bit floating point format. This is why sometimes adding a printf or cout statement to code can fix/break it, as it messes with the precision. I'm guessing some...

I think I may borrow this...one thing about being in a CS lab is there's usually a big supply of loud grammar nazis available....

On that point, Pet Peeve: People using 'less' when it should be 'fewer'
Don't ask me how, but somehow it now actually sounds wrong to use less for discrete values

Re: Favorite Mathematical Equation

Lagrange Interpolating Polynomial, mainly because the problem it solves seems to be tricky, yet if you think about it for a short while, Langrange's solution seems mind-numbingly simple.

Re: How to present CS as awesome to HS students?

What's your audience? If it's science students, you might get away with a bit more sciency-stuff. Otherwise, it's about the spectacle - interactive is always good. Your students might be media-rised, and expect coders whip up amazing code with hardly any typing, so either you say that's not true {wh...

Re: "Pix plz" Discussion

I do notice that guys will refuse to speak to me/acknowledge my existence in my comp sci classes, though. And here I was, thinking that most of the girls in CS would be sick to death of CS guys coming up to talk to them just 'cos they're a girl. Where I am, the ratio is about 15 or 20:1, though if ...
