A lot of learning followed as I’ve never use Linux outside a server environment, except for some short periods of fiddling with Pop!_OS. I’ll probably write up a longer article later, but for now the majority of my TILs the past month has been related to that project.

I had come across a lot of TIL posts on reddit, which inspired me to start building a library of personal knowledge. Since then I’ve had some months on and off, some more documented than others. I keep a TIL list in my Workflowy that I like to refer back to. This year I’d like to become better at taking notes of the random facts, computer tricks and techniques I run across. https://theodorton.github.io/7drl/ Sat, 21 Apr 2018 13:00:00 +0200 https://theodorton.github.io/7drl/ tl;dr My friend and I made a roguelike named Skyspire. It’s our first roguelike, and first game in a long while. You can find the code on Github. A week ago I decided to do a 7DRL Challenge. I’ve been tinkering with different game engines since middle school, but I tend to start projects without finishing. I read about the 7DRL concept some time last year, and I figured it seemed like a good idea to actually get to something playable. https://theodorton.github.io/about/ Sat, 21 Apr 2018 12:26:18 +0200 https://theodorton.github.io/about/ I like to code.
