This project is really incredible. You're really cramming every language under the sun into it.
What language is it written in at its "core"?
Hey, thank you and welcome back!
I've really picked boring languages here that just get the job done, as if I knew I would develop the project for eternity: C++ and Python (and SQL).
The spin-off game, which competes for attention when the languages itch strikes, also adds Go to that mix.
About the latter, did you know that
this comment of yours about performance art was an inspiration for my
Double-Triangular Architecture? (*)
(Also future FaaS migration, which I haven't followed through because I started viewing network latency as a feature, let players wait before they get pass/fail...)
(*) Hexagonal was already taken, but I bet you prefer triangles anyway...
