Is steam the only program you've noticed having issues? If not then here's a scary possibility to consider: Hardware Failure
I recently had my power supply destroy my MB and SSD and there were signs that I ignored just before it all went down.
If you still have your arch install usb available then boot from that and pick the memtest86 option in the boot menu to see if your ram has any faults.

I probably should have mentioned that I don't have a camrea, so I cannot give you any info on how that would work. My microphone works, I have shared my desktop (on KDE Plasma), and I have shared individual tabs. I can't imagine that the camera would require anything extra to work though.

I'm using pipewire with wireplumber and didn't have to install anything specific to have this all work, so I don't have any info on if there would be any pulseaudio-specific issues.

The closest I know about are:

pcpartpicker is a fantastic resource for putting together a new build.

As far as lemmy communities go, there's also !buildapc and !buildapc

There's some decent explanations in this thread: https://lemmy.world/post/1097946

One more try. I sure hope you don't have notifications enabled for all replies...
Edit: well now I'm stumped

UTC now. Am I still the ghost of federation's past?
Edit: seems so?

I had it set to localtime instead of UTC, which for me is -5 hours. Caused me a bit of grief earlier today after making a new post that started out already five hours old!

It seems like a real pickle though. What if I set my time to a year in the future and make a post? Would that post stay at the top of new all year? I guess lemmy should use the received date rather than what is sent but that could be problematic when things are bogged down or having federation issues.

@danQuix0te sorry, I shouldn't have deleted my comment. Still trying to get the time thing sorted out.

It should, but the quality of the image would be lowered doing it that way.

A group of friends and I had a blast playing this all weekend. The game and that website are both really well-made!

I'd consider all mass shootings as terrorist attacks. We used to be so scared of the idea of attacks like this after 9/11, I guess people don't mind as much when they are being carried out by our own community instead of ones that can be more easily dehumanized.
