Could I run larger LLMs with multiple GPUs? E.g. would 2x3090 be able to run the 48GB models? Would I need NVLink to make it work?

All I want is to host this on my server and have it download the latest offline installer of my GoG games automatically.

Inkscape is for vector graphics, GIMP is for pixel graphics. You probably want to use a combination of both for many situations (design the logo in Inkscape, touch it up and scale it in GIMP).

From my experience, GIMP is close to par with Photoshop in terms of both features and user friendliness. Inkscape is unfortunately much harder to use than Illustrator.

Xubuntu is more than fine. Tbh it doesn’t hugely matter which distro you use for this type of thing

Conceptually this is basically just standard encryption: some math that spits out gibberish unless you have the info to make that gibberish become something useful.

Honestly, if it’s just a small, personal project, just use common sense and take some basic precautions (e.g. use a firewall, use NGINX instead of serving Wordpress directly, etc.).

Note that CloudFlare doesn’t protect you from everything either - it only provides some very specific services. A rudimentary level of caching images being the most common one a free account level would be able to use.
