java
I coded a simple multi-threaded file server and client application in Java for a class assignment. It took me about 15 hours to realize it is exceedingly simple, complete it, and then work on the GUI for a few minutes before submitting it online.
I'm not one of those people that has a mind for code, but I wish I did because there is so much I would love to do as far as server and web applications. Oh well, I've got better things to do...
Although I did find myself looking through the Xerver source code today. Oops...
