Have you shopped eBay for used switches?

Try systemctl --user restart pipewire pipewire-pulse

I really don’t understand dbus.

I think systemd targets work opposite to your expectation. The Wants in [unit] define the things that that unit needs to already be available. For instance, you might add Wants=network.target to the unit for nginx so that it won’t try to start until the network is available. When I wrote a unit to start my company’s application, I also had Wants=postgresql.service to ensure that the database came up before the application. Remember that sysyemd tries to run as many things in parallel as it can. This is one thing that makes it much faster than classic sysvinit which started things sequentially. But it means race conditions can occur. You use Wants to break those races where necessary. The targets that you’d specify in WantedBy in [install] more closely resemble SysV runlevels. You might want to read how runlevels used to work in SysV, in order to understand systemd targets.

Every user can enable services from /etc/systemd/user for their account. If the user doesn’t log in, their instance of the service won’t start. There is a way to have user services launch without logging in, but that would obviously be nonsensical for desktop services.

I don’t think systemd would find units in /etc/systemd/user/KDE. Look at the mess that is /usr/lib/systemd/system. Organization doesn’t seem to be a thing.

For your unit files, you have Wants in the [Install] section. That is not correct. Wants belong in the [Unit] section. The [Install] section is where you define WantedBys. You may want to read the man page for systemd.unit.

To interact with user services, you do have to always use systemctl --user.

If you put your user unit files in /etc/systemd/user, they’re accessible to all users. If a particular user wants to enable the service, they can run systemctl --user enable $service. Defining the unit in ~/.config/systemd will mean only the one user will be able to start the service. Defining the unit in /etc/systemd/system indicates it is not a user service but a system service.

It doesn’t have to be the main GPU. I’m not even sure it would be possible to pass through integrated graphics. But if all you need is HDMI output, you can use the absolute cheapest GPU you can find (assuming there’s an open PCIe slot). PCIe pass-through does require CPU support (Intel VT-d or AMD-Vi) on the host and may need to be enabled in the BIOS/UEFI. I have an NVIDIA Telsa card passed through to a VM on my Proxmox server, but I’m only using it for compute; my card doesn’t even have a video output.

SMB is a network protocol developed by Microsoft. It’s the protocol used by Windows computers to share files with each other. But the protocol was reverse-engineered and a program called Samba provides SMB functionality on Linux. You only see print$ because your Samba isn’t configured with any file shares. You’ll have to configure it. You can find guides online about how to configure Samba. Samba also maintains its own user list independent of the system. That’s why your local account password didn’t work.

The primary concern is switchover time. A purpose-built UPS can switch in about 10 microseconds. Those large “solar generator” battery packs switch in about 30 microseconds. That might be fast enough, but it’s not guaranteed to be fast enough like a UPS is.

UPS batteries are only rated for a few years’ use, so you probably are due for replacement.

That is a fascinating image. It lets you see how color information is encoded in video. The vertical green bar is a glimpse of the luma (Y) channel. To the left is the chrominance blue (Cb) and to the right is the chrominance red (Cr). But the chroma channels are (obviously) supposed to be aligned with the luma, yielding full color video. Unfortunately, I can’t offer a suggestion why they aren’t aligned.

To me, that image looks like an example of indexing, not promotion.

If the pedophile site uses Lemmy software, an index of sites using Lemmy software would include it.

Is there additional information that would tilt the scale toward this being promotion rather than simple indexing?

Liftmaster and Chamberlain are the same company, so it’s highly likely (though not guaranteed) that the parts are compatible.

I recently replaced my opener in a similar situation. Mine’s chain drive and I did reuse the existing chain. I’d be less confident reusing a belt; rubber degrades faster than metal. But, based on my experience, replacing just the belt or chain isn’t much harder than replacing the motor unit. I had to loosen my chain considerably in order to get it around the new motors sprocket. At that point, it would have been just a few more turns of the tension screw to fully remove it.

What relevance has this to RedditMigration?

Gaahh, my eyes! The green! It burns!

I don’t use Mastodon myself, but I appreciate the author’s perspective.

I used to spend hours per day on Reddit. Now I visit once or twice a month, read-only. My subscription is canceled and all my posts/comments deleted. My “front page of the Internet” is now here.

::1 is a compelling alternative

Just because your system is automated doesn’t mean it’s free of bias. LLMs are trained on human-generated content. Human-generated content has biases. The model will reflect those biases. There’s also the proclivity of GPT to be confidently incorrect, like when it made up completely bogus court cases and a credulous lawyer used them in an actual case. I wouldn’t want to get my news from a source that may be lying to my face.

Mine is located in my house.

I felt like the subscription was reasonable for the amount of time I spent on Reddit.
