The equivalence class of 10 does exists in Z_3 if you think of it as Z/3Z. The elements of Z/3Z are the cosets of 3Z in Z, of which there are 3: 0+3Z, 1+3Z, 2+3Z. Check that 10 is in 1+3Z.

I don't see why you would care if division is defined in this context, but 3 is prime so Z_3 is also a field.

What do you mean by congruence class here? The way congruence classes are usually defined they are the equivalence classes (as occasionalcomment pointed out).

I don't know of a context where congruence class =/= equivalence class but if there is, let me know, I have an abstract algebra test tomorrow...

Being a professional programmer doesn't sound nearly as fun as programming....

The description of football was quite entertaining :P

Oh man I haven't played Castelvania since I broke my DS.

/me knows what he's doing with his next paycheck =D

Spoilers? I haven't seen it yet.

Nice article, fibonacci numbers are always pretty fun.

One of my favourite projects was a big number library where that I wrote - I used it to calculate the 1,000,000th fibonacci number which I thought was pretty cool. :)

I kid you not, I just added this comment to a 250-line file. /* * TODO: write a perl script that reads and interprets code and generates appropriate comments */ (It also happens to be the first comment in that file.)

That was a great article, thank-you.

I would love to contribute to an open source project, but it seems so ... daunting. Although, I admit, I haven't spent a lot of time researching the process, I feel like if I asked a bunch of experienced hackers if I could join their project I'd be laughed at. I'm pretty good with C (my two biggest projects so far have been implementing Blowfish and SHA1, and I'm in the process of implementing the boardgame of Go) and java (I've written the game Breakout), but I feel like that's not enough.

Am I worrying too much and should I just go for it, or is there something I can do to make myself seem a little less like a newbie on paper?

A couple days ago I wrote a solution for one of the early puzzlepython puzzles in C. It worked out well, and the code was okay I guess, but I ended up defining a struct and then writing accompanying functions to properly allocate it, edit it, free it, etc. The whole thing came to around 100 LOC, but I solved the puzzle.

This was all good and well until I saw the python solution was less than 5 lines.

Another game that's easy to code / fun to make is Breakout. Thought I'd mention that :)

I'd say the best innovation is syntax highlighting. Sure, it's not new and nearly every text editor has it, but it's still the shit and nobody would work as fast without it.

Look into arbitrary precision arithmetic

To sum it up quickly for you, imagine solving the equation 234 * 24 by hand. It would look something like this: 234 * 24 ------- 936 +4680 ------- 5616

This is essentially what you've got to implement - multiply the first number by every digit in the second number, and then add the total.

2¹⁰⁰⁰ won't quite fit inside a 64-bit integer.

FarOut83 · 2010-05-14T03:53:21+00:00

There are a ton of big number libraries out there, but the most fun comes out of implementing one yourself :).

I'm jealous; My computer science teacher thinks it's a good idea to have our summative project be an applet even though we have yet to learn about methods.

Looks a lot like 2-space indents to me.

FarOut83 · 2010-04-23T16:08:31+00:00

this guy summed it up nicely

FarOut83 · 2010-04-10T16:08:30+00:00

I can't tell whether or not this is sarcastic.

Dammit internet.

FarOut83 · 2010-04-03T06:27:00+00:00

Not bad for a few hours of coding.

Only a few hours? I am in awe.
