Also the Virtual Console releases, and things like the demo games in Smash Bros. brawl,

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.

It’s not separate builds, but the App Store already checks your location when you access it, and it uses that location data along with other hints you are under EU jurisdiction to decide whether to allow you to sideload or not.

Or you can use the developer tools to perform a more limited form of sideloading in any country.

The difference between the SteamDeck and the PlayStation that makes the Steam Deck a “personal computer” is that you can run whatever software you want on a Steam Deck. SteamOS even comes with “desktop mode” which works much like you’d expect a desktop Linux OS to work. If you don’t like SteamOS, you can simply install a different OS.

You can plug a keyboard, mouse, and monitor into a Steam deck

In general the Steam Deck is not the kind of device that is going to run things at max settings. You are gonna play at 720p30FPS low settings but be happy you can play at all on a train or airplane. It’s really meant to be a competitor to the Nintendo Switch than a replacement for a gaming PC.

You can stream from your PC to your couch or bed if you are at home.

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

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.
