I get really annoyed when I’m working on something these days which requires constant recompliation and Emacs puts all these files with
#’s in them.
What are those? Lock files.
What is a lock file? Something Emacs uses to detect if two instances of Emacs are editing the same file (either though a shared storage or two instances on the same computer).
I haven’t done it, but if you want you can disable it by putting this in your
(setq create-lockfiles nil)
