I've been looking for good power optimization software so I don't drain my battery while playing lightweight games. So one of the most interesting options I found was power-options , but it doesn't seem to be very updated and apparently there aren't other contributors other than two people.

Has anyone tried it? is it safe and works as intended?

I am also worried about uninstalling it. does it revert all the policies it imposes or I will need to reinstall my system to go back to normal?

I am on Fedora 43 if that matters

I see no way for someone with R4.2.4 to obtain R4.3.0 by just fetching the changes. Is that correct? If we want to maintain a copy of the latest ISO, we must grab the whole ~8gb ISO file every release?

I checked a couple mirrors (not all of them), and saw no jigdo templates.

A review of the most recent release of Manjaro. I primarily use Debian distros like Mint and MX but the overall ease and user friendliness of this Arch based distro definitely makes me want to give it a go.

I need this for political/activist purposes. When a public service blocks Tor, I want to be able to say that the public service marginalises/disservices ppl on some platforms.

My first thought was Qubes OS, because it can be setup as a Tor-only platform. The flaw of course is that users can configure it either way. So the public service would argue that it was the user’s choice to configure it to not use clearnet. If an OS were to operate purely on anonymous networks with no direct clearnet access, this would have some niche applications for activism.

Detailed episode for pairing with the very light "A Great Day for Linux". Hope you enjoy it. Since Lemmy struggles with markdown from Castopod, here is a link to the notes.

Gnome needs your support with a donate button.

How is this any different then the shit that Microsoft is pulling?

This was on Fedora 43, BTW.

I think the least that distros can do, is allow listing all packages and system settings in config files like .toml rather than having to type in every single package to install, or click through system setting GUIs to setup. Would that require using a whole programming language or system like NIx?

While NixOS works much differently from most distros, that's the only reason I use it: package and system settings in text files. If I fix something, it's fixed permanently, I don't need to hunt down files in random directories if I want to change a setting. If I ever need to reinstall the OS I don't have to write dnf install every single damn package and manually setup all that up all over again. Having daily-drove Windows macOS & Fedora as throughout the years, my setups have felt hacky as well as houses of cards as I've wanted or had to set them up again (I don't mean Fedora specifically, but distros in general).

Basically it feels insane that it's the way most linux users and servers in the world operate. If I, a humble computer hobbyist can figure out Nix, why don't more users do so, and why is Nix so niche?

I want to see either a persistent rectangle box on the edges of the region being recorded (anything outside the box isn't recorded), or dim the parts of the screen that aren't being recorded. I looked for screen recorders for hyprland & wlroots and didn't find any with this functionality. wf-recorder + slurp works for me but I want a boundary visual.

Just thought I'd throw these out there, somebody might like them. There are a lot of different ways of getting the same result.

Screenshot (I shortcut it to F6):

maim --select | xclip -selection primary -t image/png

One key and then I just select the screen shot and middle-click to paste the image where I want it.

OCR a screenshot (I shortcut it to ctrl-F6)

TMPFILE=$(mktemp);maim --select $TMPFILE.png ; tesseract $TMPFILE.png $TMPFILE ; xclip -sel primary $TMPFILE.txt

This may be a little messy as a forced one-liner. This way I can select text from an image on screen, and have the OCR'd text available with, again, my middle click.

Should go without saying it uses maim and tesseract, both should be available with your package manager of choice, and there are alternatives to both of those utilities.

I want to replace Win10 on the desktop system I mostly use for gaming. It is an older system with an Nvidia GeForce 1050ti gpu in it, which from what I found, should not be a problem. I was thinking about going with Ubuntu since it is well supported. I was interested if anyone has any opinions about this. I am also going to try and dual boot it with the Win10 for now. I purchased a new SSD drive just for Linux.

For the "old farts" out there who wants to made their ultrawide screen behave like a old TV.

Instructions how to compile, screenshots, etc are in the code.
