Just because Steam offers a DRM option doesn't mean that it's mandatory:

There's also @Deep@mander.xyz, @Beep@lemmus.org, and there was one named king but I've forgotten what instance they were on since they were last active.

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.

I use Ungoogled Chromium for teams meetings at work without issue (on arch). I also don't have an MS account.
When the other party sets up a meeting they'll send an email with a link to the teams meeting and all you have to do is follow that link to join. It also includes a phone number you can call to join by phone if for some reason you have issues.

I found the same IPs doing the same thing for my server, but one thing I noticed in the access log was that nginx was returning a 499 status code. That code means that the client closed the connection before the server answered the request. So this seems to be a deliberate attack instead of the rash of bots many have been dealing with recently. They just firehose out requests to DoS the server since pagination on services with dynamic data is expensive.

I ended up creating a fail2ban rule to add any IP to my firewall blocklist that makes a bunch of 499 entries.

Edit: I also set a rate limit in nginx for any url that has a "page" query included

If you're using linux then check if quilt is available for your distro, it's made specifically to maintain patches on top of a codbase you don't control: https://wiki.debian.org/UsingQuilt

That trackball is one of my favorites, I really wish someone would make a real replacement for it. I'm currently pretty happy with the ProtoArc EM01 NL though.
I didn't need any special drivers to change the forward/back buttons (on either of those mice), you just have to bind them in your system's settings. If you're talking about having program-specific bindings then xremap works well.

Many places in the US get their supply from Sysco: https://shop.sysco.com/

• If you're the kind of person to keep yourself busy all day, then when you're trying to go to sleep might be the first time all day you've allowed your mind to wander! You need to find some other time in the day to allow yourself to daydream. Some tips are to not read anything while in the bathroom or turn the radio off in your car if you have a commute. Maybe even schedule some time to sit and think about things if you can.
• Only use your bed for sleep and sex. Reading, eating, browsing on your phone, watching TV, or any other activity should be done elsewhere. This way you train yourself that it's sleeptime when you're in bed.
• This is probably something that can't be done if you have a rotating shift, but go to sleep on a regular schedule. Go to sleep at the same time every day. Staying up late should a rare occurrence. Your body will become tired at the same time each day and it's much easier to fall asleep when you keep a schedule.

Damn I didn't know Solutech went out of business. I like(d) their filament and still have a couple spools left.
