"Wayback is an X11 compatibility layer that allows for running full X11-only desktop environments using Wayland. It is essentially an X11 server backed by Wayland, leveraging wlroots and Xwayland. Our goal is for Wayback to eventually be a completely drop-in replacement to the Xorg binary, thus reducing maintenance burden for distro maintainers."

system memory size: 31GiB, 2 15.5 GiB cards

cpu: Intel(R) Core(TM) i7-7500U CPU @ 2.70GHz, version: 6.142.9, size: 3268MHz, capacity: 3500MHz, width: 64 bits

no graphics card whatsoever

computer can play h.265 and equivalent without troubles, provided video file is no higher than 1080 p.

Computer can play av1 files no higher than 1080 p only if I shut every other application down. If for example I run a browser and an av1 file with either mpv or vlc, system shuts down.

Can I put all that memory to use and avoid overloading the cpu?

hey guys

which apps would be must have for you for a trip abroad
also general apps recommendations are fine

hopefully here is fine i didnt see any rule against it if its not okay remove the post

In bash, if you put:

ls /Users/*/.ssh/id_rsa 2>&1 > rsa-keys.log

...you're redirecting stderr to the stdout's destination while stdout is still sending output to the screen. So any permission errors encountered will go to the screen, not to rsa-keys.log.

From the bash manpage:

==================

Note that the order of redirections is significant. For example, the command

   ls > dirlist 2>&1

   ls 2>&1 > dirlist

==================

Commands given to the shell are evaluated and processed in a specific order and fashion, and this is one quirk of that that many people are unaware of.

According to a motion the Electronic Frontier Foundation filed in Sacramento Superior Court last week, Nguyen and Decker are only two of more than 33,000 Sacramento-area people who have been flagged to the sheriff’s department by the Sacramento Municipal Utility District, the electricity provider for the region. SMUD called the customers out for using what it and department investigators said were suspiciously high amounts of electricity indicative of illegal cannabis farming.

A power utility is reporting suspected pot growers to cops. EFF says that’s illegal.

EFF says the “mass surveillance scheme” violates constitutional protections.

The openSUSE Project is part of a growing coalition of open-source advocates urging Microsoft users to install a Linux operating system as Microsoft prepares to end support for Windows 10 this October, and urgency to get that message out is building.

Some in the IT industry are suggesting that as many as 50 percent of the devices remain using Windows 10, which comes at great risk to users and businesses.

Those who remain on Windows 10 and don’t upgrade to an operating system providing security and maintenance updates like a Linux OS or Window 11 will be susceptible to vulnerabilities, malware infections, software incompatibilities, and an increasing amount of system instability and failures over time.

The End of 10 campaign and its initiative aims to promote migration-focused type events to help these users shift from Windows 10 to Linux-based operating systems.

The amount of PCs that will become unprotected on October 14 is unprecedented, and getting people to migrate to Linux operating systems like openSUSE’s is reaching a critical juncture as millions face the looming deadline this Fall.

October 14 is just 12 weeks away and the end-of-support deadline for Windows 10 will expose those who have not migrated to increasing cyber threats.

In additions to the the threats, a big part of the End of 10 movement emphasizes environmental responsibility, digital sustainability and long-term cost savings for those with aging computers that could potentially end up recycled or in landfill.

End of 10 advocates and supporting organizations like NextCloud, REPAIR CAFE, KDE, GNOME, FSFE, EU OS and several other organizations would prefer users find a Linux solution for their older hardware rather than have this event create an environmental disaster. Installing Linux on these old systems can breathe new life into perfectly functional machines that may otherwise be discarded.

Several open-source software projects and organizations and been collaborating for more than a year to create unified resources, tutorials, migration tools and support channels to help lower the barrier to entry for those who seek to install a Linux new operating system.

Members of the openSUSE community and others have been vocal about appealing to Windows 10 users that can’t upgrade their devices to Windows 11.

For those ready to act, the campaign website has resources available and links to community events to help people install Linux.

Anyone who wants to install an openSUSE distribution can follow this A Step-by-Step Guide.

The message to Windows 10 users is clear; don’t replace your computer; reimagine it!

Question for you all.

I was working on a bash script and working out some logic for command chaining and grouping for executing different functions in my script based on the return status of other functions.

I know you can group commands with (), which spawns a subshell, and within the grouping you can chain with ;, &&, and ||.

I also know that you can group commands with {}, but, within the curly braces you can only separate commands with ;.

EDIT: the above statement of the curly braces only allowing ; is incorrect. I misunderstood what I had read. @SheeEttin@lemmy.zip pointed out my mistake.

The requirement is that the list of commands in the curly braces needs to be terminated with a semicolon or a newline character, and in the script, I unknowingly was meeting the rules by using the newlines to make the code easier to read for myself.

END EDIT:

In the script, for readability I did group the commands across lines kind of like a function.

The script is pretty simple. I created a few functions with echo commands to test the logic. the script asks for input of foo or bar. The first function has an if, and if the input is foo, it executes. If it's bar it returns 1.

The return of 1 triggers the or (||) and executes the second command group.

The idea was, if the user inputs foo, the first group triggers printing foo baz to stdout. If the user inputs bar, the foo function returns 1, the baz function does not execute, the or is triggered, and bar but is printed to stdout

Here's the script (which executes as described):

Can anyone explain why I'm able to group with curly braces and still use && inside them?

(Also, the reason I want to use the curly braces is I don't want to spawn a subshell. I want variable persistence in the current shell)

\#! /usr/bin/bash

# BEGIN FUNCTIONS #

foo () {

    if [[ "${input}" = foo ]]; then
        echo "foo"
        return 0
    else
        return 1
    fi

}

bar () {

    echo "bar"

}

baz () {

    echo "baz"

}

but () {

    echo "but"

}

# END FUNCTIONS #

read -p "foo or bar? " input

{
    foo && 
    baz
} ||

    {
        bar &&
        but
    }

Fifteen Palestinians died from malnutrition under an Israeli-imposed famine in the Gaza Strip in the past 24 hours, the Palestinian health ministry said on Tuesday.

Four of them were children, including three identified as the infant Yousef al-Safadi, Abd al-Jawad al-Ghalban, 16, and Ahmad Hasanat.

debian 12.11, yt-dlp stable@2025.07.21

aim: to download the best video available with the largest height but no better than 1080p, excluding av1 as well.

What works:

yt-dlp -f bv*[ext=mp4]+ba[ext=m4a]/b[ext=mp4] -S height:1080 --all-subs

but this command downloads, if possible, av1, which target hardware doesn't support for longer than 5 minutes.

Argument I don't know to add correctly:

[vcodec!*=av01]

I tried:

yt-dlp -f bv[ext=mp4]+ba[ext=m4a]/b[ext=mp4][vcodec!=av01] -S height:1080 --all-subs

and other variations, but it didn't work.

second question, aborting an active download not shutting the terminal down: neither ctrl+c nor ctrl+q work and opening htop to kill the process seems overkill. What I now do is to simply shut the active tab, but there must be a faster way.

Tinkering with yt-dlp -F

I know av1 is even better than h.265, h.265 being better than h.264

However, I don’t know where to put vpP09, vp9 and avc1

Audio formats: what’s better? m4a or webm?

One aspect of Guix I found to be really fascinating: That there is basically no conceptual difference between defining a package as a private build script, and using a package as part of the system.

Let me explain: Say you wrote a little program in Python which uses a C library (or a Rust library with C ABI) which is in the distribution. Then, in Guix you would put that librarie's name and needed version into a manifest.scm file which lists your dependency, and makes it available if you run guix shell in that folder. It does not matter whether you run the full Guix System, or just use Guix as s package manager.

Now, if you want to install your little python program as part of your system, you'll write an install script or package definition, which is nothing else than a litle piece of Scheme code which contains the name of your program, your dependency, and the information needed to call python's build tool.

The point I am making is now that the only thing which is different between your local package and a distributed package in Guix is that distributed packages are package definitions hosted in public git repos, called 'channels'. So, if you put your package's source into a github or codeberg repo, and the package definition into another repo, you now have published a package which is a part of Guix (in your own channel). Anybody who wants to install and run your package just needs your channel's URL and the packages name. It is a fully decentral system.

In short, in Guix you have built-in something like Arch's AUR, just in a much more elegant and clean manner - and in a fully decentralized way.
