I think compose files are usually pinned to a version, or use a .env file that needs to be changed to update to a new version.

I personally don’t update very often; usually not until I’m forced to for some reason. I find that just checking the documentation for any upgrade/migration guides, and doing it manually is sufficient. I don’t expose this kind of stuff publicly; if I did, I’d probably update regularly.

Used it for a ML MOOC a long time ago. Switched to Python/Numpy for better general programming features. Numpy has pretty good syntax for matrix computation, IMO.

I had a Mox and it was the most stable router I’ve ever had. Never had to power cycle it, and I even have to power cycle my fancy Asus somewhat often.
