Since I lost my laptop last summer, I also lost access to two short coding projects (like, 2 hours tops) that I'd done. One was following along with a 2-d planetary orbit simulator, to learn a bit about OpenGL. The other one was to take a text file and exchange each character for its equivalent on an opposite keyboard mapping (QWERTY <--> DVORAK).
I'll probably want to remake both again; I still even now don't understand Lagrange points (the whole reason I did the tutorial was to get that simulator up and running for myself), and I'd like some basic cryptography on my personal journal entries that I can easily unscramble.
Anyway, I also picked up this new project: trying to get this program (a Verlet Integration particle simulator), whose code is public, to run on my Windows laptop. It was written for MacOS and I've run into issues my first time using Makefiles to try to get it working.
