• OS:
  • Arch Linux or OpenBSD, depending in how I feel
• Editor:
  • Micro on Linux
  • mg(1) on OpenBSD
• Plug-ins:
  • Micro has support for a few linters, which is all I really need
  • mg(1), meanwhile, doesn't even have syntax highlighting
• Terminal:
  • Kitty on Linux
  • XTerm on OpenBSD
• Shell:
  • Zsh on Linux
  • ksh on OpenBSD
• Version Control:
  • Git is the only realistic option (though Mercurial and Fossil are nice)
• Code Hosting:
  • Usually Codeberg
  • I also have sourcehut
  • My Formula Student team uses GitLab
  • My university and another society use GitHub 🤮

I usually licence my work under GPL if it's a large project, or Beerware if it's something smaller (or if it's for internal use in one of my societies).

Any coursework I do, however, gets licenced under BSD-3-clause. For this, GPL would be too restrictive and Beerware would be too informal, and BSD-3-clause is a nice middle-ground (as far as I'm concerned).
