I had just posted about it on my page, but he's actively developing an open source HMD driver for Oculus headsets so that people who bought it before the Facebook account mandate can use it without privacy concerns and without any Facebook software/drivers on their machine. It also allows owners to use their devices on Linux. What he's doing can also carry over to Microsoft's proprietary WMR headsets.
@bzg Ubolonton, developer of emacs-tree-sitter package should get some deserved attention: https://github.com/ubolonton/emacs-tree-sitter. Outside from that, the lsp-mode team or Joao Tavora could need more incentive as well: https://github.com/emacs-lsp/lsp-mode. https://github.com/joaotavora/eglot.
Not sure if any of them are actively taking donations though...
IMO, enabling tree-sitter and lsp protocol seems like an important step for emacs :)
