This page lists some of the software that I've written or that I am using that I think might be useful to other people.
http://good.math.iastate.edu/grout/graphs/
This is a database of all 13,598 graphs with 8 or fewer vertices. I'm in the process of updating the database to include graphs with 9 or fewer vertices. I'm also in the process of writing a PyQT front end to the database.

This is a plugin for the DokuWiki wiki (the software I used to create this website and that I'm using now in my classes). The plugin allows you to pass commands to external software and embed the resulting images in the wiki page. The nice thing about this is that you don't have to create images with other programs and then upload them to the webserver. Additionally, the changes are tracked between pages (so, for instance, you can change a graph on a page and old versions of the page will still display the old version of the graph).
http://math.byu.edu/~grout/software/dokuwiki/newpagetemplate
This is a plugin for the DokuWiki wiki. The plugin allows you to specify a template and also replacement variables for the template for a new page creation. The motivation behind developing this plugin was a need for a way to present a student with a way to create a homework page from a predefined template. I made it possible to have variables in the template that could be replaced with values I pass the wiki.
Here is some software that I'm using on my webpages.
I use DokuWiki to create my website and my class websites. I picked DokuWiki because (not necessarily in order of importance):
I'm using jsMath to display mathematics on my course webpages. I chose jsMath because:
