not much
I only program something when I think I have a good idea, and most of the time when it helps me directly.
http://www.wneary.com/java/javaprogramming.html so far anything woth mentioning is a a prime number program series that I started (1.0) then I saw a friends c++ prime number program. His was soo much faster, the competition was on (at least in my eyes). After 2.11 (I know it sould be 2.1.1 but I am too lazy to fix it right now) another friend made one like mine in java only with a linked list and made it multi-threaded. By this time it was all or nothing, I made 2.2 feature pause continue and stop which is always nice (mine is as fast as it will get unless I implement a new algorithm).
I plan on making a program that will run on the server that will on the fly generate a tileable picture for my website and replace the old background as often as I want (it will probably be every 1/2 hour or so).
So yeah I'm going on and on about practly nothing... but it is my first true GUI.
