The specification https://eris.codeberg.page/spec/#name-introduction was mentioned on the plan 9 mailing list https://marc.info/?l=9fans&m=176805933123451&w=2.
ERIS allows you to make content available robustly over computer networks by using identifiers that are location independent and network-optimized. It can be used as a building block for decentralized and fault-tolerant applications, some examples being:
- file-sharing
- de-duplication of content
- reproducible and deterministic identifiers of content
ERIS is a network optimized form of content-addressing.

Sounds interesting, I need to look into this and perhaps try it.
The blog has other interesting articles and a style selector "theme".

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.
