Practical /prog/ramming

Name: Anonymous 2009-06-24 0:09

What are some practical things to program? I am in the midst of making an RPG, but I am just curious as to what /prog/ does in their spare time.

You can post practical or impractical programming, I don't care.

Command line tools, algorithms, Source conversions.

Judging from the blogs maintained by our regulars, recent /prog/ projects seem to be:

1. A Bézier curve plotter.
2. Some type of Javascript/Sepples hybrid monstrosity, I don't know.1
3. Heavy drinking.
4. Quietly sulking over being banned.

I'm writing a spaced repetition flash card program, since the programs I know of don't allow for easy card generation from source data. Doing it in Common Lisp, but I'm considering a future port to Emacs Lisp, so it can run in Emacs without an inferior Lisp and so it can piggyback on Emacs graphics support.

Next up is a rogulike that improves your arithmetic skills.

I wouldn't say most, it's only about half.

Let's say you have 3 possibilities. A (above average), B (at average), C (below average). The distribution in a typical population will look like:
B,B,B,A,B,C,C,B,B,B,A,B,B,B,B...

Even though this respects a gaussian distribution, it is easily seen that below average, C, is represented 2 times on 15, which is definitely not ``about half''. Ergo your wrong bitch.

Actually, because quality of a person is a continuous variable:
Pr(at average) = 0
Pr(above average) = 0.5
Pr(below average) = 0.5

A typical representative sample might look like:
A,C,C,C,A,C,A,A,C,A,C,C,A,A,C,A,A,C,A,C,...

This is what haskell programmers actually think

GP2X programming is fun, I recommend that. The newer versions of it might be a better choice, though.

Firefox extensions would be a good choice, because they can prove so useful (and thus it feels like you're actually doing something worthwhile), if it weren't for XPCOM, Sepples and all the other nasty stuff that generally gets involved.

>>17
That depends on your definition of `at average'. If you mean `within one standard deviation from the mean', then about 68% of the people fall meet this definition. Of course, you could take it literally, in which case you would be technically correct but missing the point.

Goddamnit I've been writing a database/tool to help correlate info between modules used by my company's softare and the test vectors that -should- test them.

Yes this is in my own time. And I'm a dev guy, not a fucking QA pleb. Fuck if I know why I thought this would be fun to do. It really kinda was for a while to just do something different, but cannot sustain 16 hour programming days.
