I learned how to program on a TI-83 graphing calculator. I was bored in class and I made a simple text-based blackjack game.

Later my friends and I would use the link cable to share programs between our calculators, and I would pour over the source code and try to understand everything. There was an ASCII fighting game I loved and I added new moves and characters.

Once I learned how to "view source" a website I started doing that everywhere and figuring out how the Web worked. That, plus a Linux install disk and an old, case-less desktop got me on the road to where I am today (supporting a SaaS company as an Infrastructure Engineer).
