Greetings and Salutations! My name is Thomas Cort. I live in Gatineau, Quebec, Canada with my wife Bridget. I'm into computer programming as well as electronics. I created this website to share some of my personal projects and hobbies with the world.
Ever since I took a Compilers and Interpreters class at Bishop's University, I've been fascinated by programs that compile and/or run other programs. I finally had a bit of spare time to build an interpreter, and developed 'edgar', a small LISP Interpreter written in C. It doesn't have a lot of built-in functions yet, but it is already quite functional. It allows users to define functions and supports some of the classic intro to LISP programs: factorial, fibonacci, GCD, LCM, and more. I've put my code up on github for anyone interested: https://github.com/tcort/edgar/.
I designed and built a terminal node controller (i.e. 1200 BAUD radio modem) from scratch. I designed the circuits, laid out the printed circuit board, hand soldered the surface mount components, developed the firmware, developed the software, and wrote documentation. The only part I didn't do was manufacture the PCBs. It was a great learning experience. I've put my code and design files up on github for anyone interested: https://github.com/tcort/va2epr-tnc/.
When I first got my copy of "Operating Systems: Design and Implementation" (2nd Ed), I would day dream about how cool it would be to work on Minix. Years later, I had the good fortune of being selected to work on Minix as part of Google Summer of Code. Even though the summer is over, I still continue to contribute as a committer. Some of my more interesting contributions include 10+ drivers for Minix/arm (blog), implementing the adjtime() system call and porting OpenNTPD, implementing UNIX domain sockets, porting many 3rd party applications, and importing over 50 utilities from NetBSD's base system.
I'm a recreational runner. I usually go out 3 or 4 times a week and run for fun. I've completed 3 half-marathons (13.1 miles) and several 5k and 10k races. I'm not a speed demon, but I have a good time enjoying the outdoors. My favorite time to run is late fall.
Geocaching is treasuring hunting for the 21st century. You get clues from the official website and use a GPS to find hidden containers. Usually they're in interesting locations. It's a great way to explore the outdoors with the help of some advanced technology.
Amateur radio is a neat hobby where licensed/certified individuals setup radio stations and make contact with other radio amateurs from all over the world using a variety of "modes" including voice, Morse code, and digital modes. My callsigns are VA2EPR and KB1EPR.
