Practical /prog/ramming

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.

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.
