I'm implementing an interpreter, and wondering how often I should check for interruptions (e.g. Ctrl-C). I don't want to spend too much CPU time checking whether I've been interrupted, but I also want slow programs to stop promptly. It's tricky.

One interesting design choice in Emacs that I haven't seen in other editors: reserved shortcuts. An Emacs extension shouldn't use F5 through F12, or Ctrl-c LETTER. This lets users configure their own shortcuts. https://www.gnu.org/software/emacs/manual/html_node/emacs/Key-Bindings.html Does it exist elsewhere? I miss it in VS Code, where e.g. all the Fn keys are already assigned.

A great deep dive on building GitHub's code view, optimising React, scaling to thousands whilst supporting both Ctrl-F and syntax highlighting:
