I think IETF BCP 47 is the way to go for this (and is rougly a superset of what you’re saying). They also define a “more/less specific” selationship between tags so you can ask for “en-CA” and have the system decide “en” is still appropriate.

These days I think OMEMO is a better choice than OTR, if your client supports it.

What makes you think that Christians, as a whole, deny science?

I don’t know what your exact criteria for “sportswatch” is, but I’ve been very happy with my Bangle.js 2: https://banglejs.com/

This is not true. In fact, Guix doesn’t use systemd at all. When managing an operating system installation Guix uses its own init system called the Shepherd.

Elogind is a project extracted from systemd originally for use in Guix systems.
