Here are some links and files of various programming projects I have worked on. I don't program much anymore except some PHP on websites I run, but some of the stuff I did in the past may still be useful. Or maybe not.

I worked on the FreeRADIUS project for a while. I contributed the rlm_fastusers module as well as working on a lot of the SQL auth, accounting, and OBDC code.

I cannot imagine that anyone still uses any of this, except FreeRADIUS of course. But it's here just in case...

Many years ago I wrote a utility called "vrflash" for the Agenda VR3, a linux-based PDA made by a company called Agenda Computing. I even ported it to windows. Here is the windows binary.
unix source
csv2contacts was written for the same device. It took csv separated input and converted it to the DB format used by the Agenda VR3 - unix source
Finally, I wrote a couple of statistics programs in perl for the Livingston portmasters. Pmstats analyzed the text logs generated by a portmaster - perl source
Pmrats did basically the same thing but using SQL - perl source
