XenoTrout.com itself is a programming project of mine. It is written in CSS, XHTML, PHP and SQL. There are even some Apache server tricks. At the bottom of each page is a link to view the PHP source of that page. This simply adds a query string of "src". This source viewing is made possible by a script I wrote.
I have written a few programs, shell scripts, etc. Mostly for POSIX-like (okay, specifically for GNU/Linux) systems. Here are the ones I have bothered to make public. They may be trivial, they may be poorly written, they may even be buggy. But here they are. I welcome modifications, patches and feature requests.
Don't want to download and run a program on your own system? You can run some of my programs directly from my server.
