Linux

When you cryptsetup luksFormat, LUKS2 cryptography defaults to argon2id, a competition-winning gpu-resistant multi-core memory-hard algorithm thingy. Only problem is everyone only supports pbkdf2 instead :3

• GRUB had an argon2id support patch in the works. Buuut it stopped because a version-pinned dependency added argon2id support, and GRUB wants to update lib x to update lib y to update lib z to update said dependency (2 years later... I'm here D: )
• systemd-boot is simple and doesn't support argon2id
• efistub, i.e. making the kernel boot itself (i think?), necessitates secure boot and I'm not sure that's the best way to do this (Ventoy can bypass secure boot with MOKMANAGER funkin' anyway, can't it?)
• Raspberry Pi's bootloader might support argon2id? idk

Not to be deterred, I tried manually patching GRUB (tried with aur on a usb, then with portage) but I don't think these are supported with the latest GRUB. (Attempted with whatever the aur package uses, then Gentoo's grub-2.12-r4, then Gentoo's grub-2.12-r5, then git cloning and checking out older versions manually, then picking the earliest 2.12 archive.org tarball to patch lol. All failed with "couldn't find disk"-esque issues)

Does anyone have this working at or after Nov 2024? And better yet, am I missing something obvious ¯\_(ᵕ—ᴗ—)_/¯

I find this hilarious. Is this an easter egg? When shaking my mouse cursor, I can get it to take up the whole screens height.

This is KDE Plasma 6.

The petition is open to all EU resident. The goal is to replace all Windows in all public institution in Europe with a sovereign GNU/Linux.

If the petition is successful it would be a huge step forward for GNU/Linux adoption.

CachyOS does compile packages with the x86-64-v3, x86-64-v4 and Zen4 instruction set and LTO to provide a higher performance. Core packages also get PGO or BOLT optimization.

CachyOS utilizes the BORE Scheduler for better interactivity, and offers a variety of scheduler options including EEVDF, sched-ext, ECHO, and RT. All kernels are compiled with optimized x86-64-v3, x86-64-v4, Zen4 instructions and LTO to be optimized for your CPU.

I like the sound of that for my new gaming distro, but I really feel more comfortable in the .deb ecosystem.

Linux kernel 6.12 is one of the most significant releases of the year, delivering a feature nearly 20 years in the making: true real-time computing.

I have a multiboot system. One of the installed OS's does not use the NVMe SSD installed on the motherboard at all.
At the time of taking the screenshot, all the SSD partitions are unmounted, so apart from detection, the SSD is mostly unused.

• I would like the temps to drop down to SYSTIN (≈35°C) levels.
• I know, it's right next to my GPU, but I am not doing anything GPU intensive, the GPU temps are ~37°C ^[apart from GPU memory, which is 48°C due to the awful AMD 7th gen Zero RPM, which has no workarounds on Linux]

For the unmounted and unused HDDs, I just use hdparm -Y, but there seems to be nothing in terms of that for the SSD. And even though I appreciate the additional heat in winters, this is going to be too expensive for me. I'd rather burn some cheap Nichrome than my data storage device.

I checked out a Debian forum thread and from that, I checked the following:

❯ sudo nvme get-feature /dev/nvme0 -f 2 -H
get-feature:0x02 (Power Management), Current value:0x00000004
        Workload Hint (WH): 0 - No Workload
        Power State   (PS): 4

Showing it is already in the lowest power state.

I have no active cooling setup for the SSD from my side. This becomes relevant soon.

• Checking the SSD temps (using the same widget as in the image), the temperature on Sensor 2 starts out at ~40°C (after a normal reboot) and slowly increases to >50°C as shown at the start of the graph. Power State (PS) is still 4.

• Running KDE partitionmanager, which probably does some reading to check the partition information, at 50°C stage, causes a temperature drop, as shown in the image.

• Running KDE partitionmanager right after reboot, when the temperature is increasing very sloowly, seems to do nothing significant.

• Turns out that after a few minutes of System Standby, the SSD doesn't return to PS: 4, so I have the culprit.
• Running partitionmanager after that causes it to go back to PS: 4

So we have a solution! All I need to do is run partitionmanager on wake. nlol jk

Motherboard: MSI MAG X570S TORPEDO MAX (MS-7D54)
SSD: Samsung 980 512GB (correct firmware, bought long before the fakes started coming out)

Incus is a virtual machine platform, similar to Proxmox, but with some big upsides, like being packaged on Debian and Ubuntu as well, and more features.

https://github.com/lxc/incus

Incus was forked from LXD after Canonical implemented a Contributor License Agreement, allowing them to distribute LXD as proprietary software.

This youtuber, Zabbly, is the primary developer of Incus, and they livestream lots of their work on youtube.

My go to back in The Day was just Ubuntu because I was lazy. We're talking the 14.04/16.04 days. Ubuntu was simple and mostly just worked. I now find myself needing to de-spywareify as the coming administration is likely to force Microsoft into tracking "dissidents" so need to get back into weaning myself off the Windows teat.

I recently dualbooted my main desktop with Ubuntu 24.04 and have been... entirely underwhelmed. The whole separation between APT and snap packages doesn't work well together and is really the big problem I have, as a lot of standard deb packages just refuse to install properly now. the UI is hard to use and doesn't make me happy, and it's not been playing nice with my Zen 4 desktop when it comes to ACPI power states (no sleep, doesn't reliably turn the power off when i ask it to turn off, etc). So overall, I am just not terribly interested in using Ubuntu anymore.

What I primarily want is the sort of "mostly just works" like old 16.04 but still gave you the full ability to monkey under the hood- and is also something based on a normal distro that most people write guides for because I am a smoothbrain. Should I just head to using basic plain jane Debian or something?

This is great. Having access to all apps is nice, but it is also useful to know how and if flatpak apps are verified.

This mostly means they are packaged by official developers. This guarantees better security, as the chain of trust is shorter, and better support.

Starting with Fedora 42 the KDE Edition will be at the same level as the Fedora Workstation Edition that uses GNOME.
