I just realized that the 6.17.0-14 kernel on my Mac Mini running #LinuxMint must have removed the WiFI driver. How do I get a bug report filed for that? #Linux

Maybe I'm not doing myself any favors by asking this, but what's your overall attitude toward Omarchy?

Okay, and I'm also interested in your opinion. 🤗

More moaning about #linux. I'm trying to get a discourse server off the ground. Why the fuck do they insist on installing non-OS stuff in the middle of all the OS stuff.

/var/discourse is not a good default. And then fucking docker wants to be /var/lib/docker. Never mind how /var/lib doesn't make any goddamn sense.

Related to my earlier discussion of hard drive partitioning. What I would like to do is have a volume that is not the operating system, but is instead all the application data. The discourse data, database, assets people upload, etc. That way I can have this nice virtual disk that encapsulates it. I could theoretically build a new node, attach this drive to the new node, and migrate the site. I can snapshot that drive more frequently than, say, the OS drive. Lots of benefits to encapsulating it.

For about two years, I couldn't figure out why Scrivener kept turning off while I wasn't looking. It was baffling.

Apparently, the Windows* version has an option that says "Turn off after 30 minutes of inactivity," and it's on by default.

Maybe the Apple version does, too, but it never came up.

Mystery solved.

I was messing with the #debian installer and its disk partitioning. I don't understand this at all. This is plain stupid.

If the partitioning scheme includes swap, it should be the last partition on the disk. This installer frequently puts it in the absolute worst possible place: the middle.

That's dumb, especially in a virtual world where hard disks trivially change size.

See, what if I decide to make this disk bigger? What if I decide I need more swap? If swap is the last partition, it's trivial.

1. Increase the virtual disk size
2. Boot to single user mode
3. Delete the swap partition
4. Expand the penultimate partition to encompass the new space I created, minus the amount of swap I want.
5. Grow the filesystem in the penultimate partition
6. Create the swap partition in the final position again.
7. Boot.

But when you stick swap in the middle of the fscking disk then it makes changes really non-trivial. You really can't change anything.

The only partitioning scheme that gets it right is the "All files in one partition" scheme. Since there's just the one root filesystem, it puts swap at the end.

Also, it appears that you cannot change the size of partitions in this view. Like, if I wasn't happy with 1.1G of swap, tough noogies. That surprises me. The entire POINT of an interactive installer like this is to allow me to specify high-level things like "Gimme 2G of swap" and have the installer recalculate all the start/stop partition values and such. I've done plenty of debian installs, but this is the first time I stopped to notice how bad this is.

Some of you may argue that the problems I cite aren't important. But I defy you to come up with a good reason why one should put the swap partition in the middle of the partition table. You can argue it doesn't hurt, but you cannot argue that it does something good.

RE: https://chaos.social/@davidak/116205913072553471

After some research today it becomes clear that you can't have a linux system without running LLM generated code, since the linux kernel itself and also systemd has it.

Maybe not running LLM generated code becomes a niche thing like running linux-libre and libreboot. It is not something the average user can achieve.

We need a more specific approach to handle software with LLM contributions.

Any #Linux users on #IntelArc here?

I bought an Intel Arc A750 and it looks fancy, works for gaming and AV1 encoding (after adding "vpl-gpu-rt" recompiling the kernel for that I guess), but I cannot control the fan at all!

The fan mode is "automatic" and on full power all the time which is crazy loud.

I tried everything, updated my kernel to 6.18 longterm, used a windows install to use that intel tool to upgrade the GPU firmware, no change.

Now I plan on connecting the fan to the case fan connector and controlling it through BIOS (I can read temperature now so that is okay-ish I guess).

I couldn't find a single report of this being a thing at all, do these GPUs really have THAT shitty drivers? I thought it was just performance issues (which I didnt really see).
