This is the home server of Geoff Stratton. The server itself lives in Softlayer's DAL02/06 data center in downtown Dallas, Texas, geolocation 32 47 32.599 N 96 48 53.11 W 125m 10m 100m 10m. There's a little more about me on the About page.
I use this place mostly as a personal knowledge base, although I keep it public in case anything useful emerges. All of this worked for me, but caveat emptor, and don't go handling snake-skin.
Software Development
These are programs and scripts I've written over the years in various languages and frameworks. More general notes on development, databases, specific platforms and administration are in the "Linux/Unix" section below. I'll continue adding stuff here as I have time to clean it up and test it.
