I definitely understand about how seriously you take privacy. For a personal project, I wouldn't think twice about sending it your way.
Source Code Pro is my usual default for a good looking monospace font, but Fira looks like a good choice. How do you go about finding monospace font's width to height ratios? I had do dive into SVG versions of Source Code Pro and doing some hands-on testing to come up with a ratio of 0.6.
Yeah, I'm not doing anything with a margin. In hindsight, I probably should have.
I actually manually picked the code I wanted to include in the poster. I imagine doing this in an automated way would be a much more difficult problem... Do you just ignore certain files based on filename patterns? e.g. /node_modules/, etc...
Yeah, there are a few places where I can parallalize the process. There's definitely a lot of room there for future work.
3 to 4 seconds is _very impressive_. Congrats!
I'd definitely push others to go with your solution, if it's a possibility. The elixir_poster project is really just a hacked together project to build a one-off (two-off, I guess) poster for myself.
