Independent Work

Home Internet system

"Back in the day" it used to be interesting to cite the fact that I had a system that was on the Internet from home, complete with various servers and firewalling. These days, no one bats an eye, but there it is anyway. Though records have shuffled around a bit, I registered AJS.COM in 1994, and Internet Archive shows that I had Web services running in late 1996.

I also do a fair amount of programming on my own time. I am the author of a number of tools including plug-ins for The GIMP and library modules for Perl. If you want to see a sample of my work, download the latest development version (1.1.4 or later) of The GIMP source code and look under plug-ins/perl/examples/image_tile.

Samples of my Work Online

search_sample: http://www.ajs.com/~ajs/search_sample.py

A simple binary search tree implementation. This isn't terribly practical or interesting, but I didn't have an example of my recent work in Python that I could use freely. The following examples are fairly old Perl code from my Perl days, but they're also more practical examples.

mkpasswd: http://www.ajs.com/ajswiki/Mkpasswd

Password generation is a hard problem that I've written a program to solve. It has followed me from job to job getting better along the way. You can have a look at mkpasswd's source code and documentation from my Web site.

mktreasure: http://www.ajs.com/d20/mktreasure

More recently, my gaming interests lead me to write the world's most complete d20 SRD 3.5 treasure generator. In case that means nothing to you, feel free to check check out its Wiki page (mktreasure) on AJS.COM which includes links to the source code.
