Coding is bit hit and miss. Long back I had used unity and c#, (both were new to me). As of recent, I’ve been trying to learn godot and c# since I’ve played a few 2d games. Maybe these would be a good starting point. You may find other engines that require less to no coding as others suggested to be better.

Comics could be funny, informative, or maybe just an “today was interesting” thing, or even introspection. Anything that feels interesting to you.

Videos are even more open, you can make videos on a lot of topics, anything you find interesting, anything you want to teach, and so on. Gaming videos are also nice, once you’ve started you can learn a lot and settle on something that you’ll like (what you play, how you play, how you communicate with your audience,…). There’s two big places - YouTube and Twitch. Both are I’d say good places.

A low end computer should hopefully not be a dealbreaker for you, it should be a good way to start. If you’re worried that is the case, you can look around and confirm if it can be used to start.

Photography - added benefit is that you will usually go out for this

Music - an instrument is good

Drawing/Painting

Programming (hit or miss, I found learning unity was fun)

Video making - recording video games playthroughs, cooking, and so on.

Finally, one that usually everyone probably also may mention - Therapy - not a hobby but having to be able to talk about it is often good

This is of course not an exhaustive list - but it depends on what your interests are. Hope this is a good pointer to what you’re looking for.

A smile where the person is so full of it that you want them to “eat shit” (you hate it)

A regular ethernet cable is sufficient in most cases. Except for ancient network cards, most newer ones know to flip the wiring to be able to communicate between two computers.

The only thing is that you need to set the network options manually in both computers - set the IP address and subnet. Then just transfer it using any network file sharing protocol. (Windows already has file sharing, Linux you can use sftp, or use a http server)

Edit: Looks like you asked specifically for USB. Sadly that is not possible specifically with usb since both devices are “hosts”. I provided this solution since ethernet cable are also very common and cheap to use
