That's one hell of a story! Myself, I only got as far as implementing a CMS with a virtualized filesystem with symlinks (and I think it was even rudimentarily distributed); lots and lots of pointless wheel reinvention, but I've learned tons of stuff and ultimately managed to use it to skip a subject at university. What I didn't manage to do is to use it to build my website (ended up keeping my Wordpress blog, later replaced by a DIY static site generator).

I've seen you around here a lot and enjoyed your comments, but until now, I never realized you're the author of "Crafting Interpreters" and "Game Programming Patterns"! These are some of the best resources I've ever read on-line! Thank you for doing those!
