Interesting article describing the use of org-mode to define keyboard maps for QMK. Found on Sacha Chua's blog https://sachachua.com/blog/2025/11/2025-11-24-emacs-news/
Gave me the idea to look into QMK for my Sun keyboard translator.

See also https://lisperator.net/s/slip/ for an in-browser Lisp implementation.  The latter (SLip build fc7e29c 2025-10-21 20:08:55) does not compute (tan x) correctly, I reported this on 2025-10-30. SLip build d1c5dfe 2025-11-03 22:51:27 has working atan (with one argument only) and tan functions.
It is lacking apropos and describe, which would be very useful. https://jscl-project.github.io/ does have these functions.

BorgBackup (short: Borg) is a deduplicating backup program. Optionally, it supports compression and authenticated encryption.

The main goal of Borg is to provide an efficient and secure way to backup data. The data deduplication technique used makes Borg suitable for daily backups since only changes are stored. The authenticated encryption technique makes it suitable for backups to not fully trusted targets.
