Software

So far, I have only managed to include a small section on the dimdimIP package. The rest will follow soon, hopefully...

Here you can find an archive with the files necessary for compiling dimdimIP, a heuristic method for solving large-scale integer programming problems. The code is written in ANSI C, and is distributed under the GNU Public License. To understand the algorithm and the significance of the command-line arguments, you may want to have a look at the corresponding writeup.
Instructions for installing and running dimdimIP are available in the README.txt file included in the archive. In order to read .mps files, you'll also need a copy of lp_solve, an excellent free solver for linear programming problems. It's available under GNU LGPL from the following Yahoo group.

Here you'll find a couple of Perl scripts that I wrote for the Introduction to Systems Programming course I took a while ago. They were tested quite extensively at the time, but that is still no guarantee that they're bug-free. :)
badLinks.pl - a script that checks for broken tags in HTML files.
SpellCheck - spell checker that uses a specified dictionary to report missing / incorrect words
nhttpd - small web server (unfortunately, it requires a couple of external files, so you'll need a workaround in order to use it)
