Over 700 years. A tower originally built in 1310. The island it’s on is an exclave that is technically part of Hamburg.

Without some sort of reproducible builds (which are really finnickey to actually get) this doesn’t really help though. Adding some set of malicious patches before doing the binary release is trivial.

I think major training should just be done on dedicated servers/on the cloud. That being said it is very helpful to test locally, so in case you are planning on using Nvidia equipped servers just get any somewhat recent consumer Nvidia card and you can always run locally on some sample data and test much more easily.
