  • I agree that, theoretically speaking, YouTube might be protecting some end users from this type of attack. However, the main reason YouTube re-encodes video is to reduce (their) bandwidth usage. I think it’s very kind towards YouTube to view this as a free service to the general public, when it’s mostly a cost-cutting measure.


  • Good point, though I believe you have to explicitly enable AV1 in Firefox for it to advertise AV1 support. YouTube on Firefox should fall back to VP9 by default (which is supported by a lot more accelerators), so not being able to decode AV1 shouldn’t be a problem for most Firefox-users (and by extension most lemmy users, I assume).


  • About the “much higher CPU usage”: I’d recommend checking that hardware decoding is working correctly on your device, as that should ensure that even 4K content barely hits your CPU.

    About the “less sharper image”: this depends on your downscaler, but a proper downscaler shouldn’t make higher-resolution content any more blurry than the lower-resolution version. I do believe integer scaling (eg. 4K -> 1080p) is a lot less dependant on having a proper downscaler, so consider bumping the resolution up even further if the video, your internet, and your client allow it.


  • I believe YouTube always re-encodes the video, so the video will contain (extra) compression artefacts even if you’re watching at the original resolution. However, I also believe YouTube’s exact compression parameters aren’t public, so I don’t believe anyone outside of YouTube itself knows for sure which videos are compressed in which ways.

    What I do know is that different content also compresses in different ways, simply because the video can be easier/harder to compress. IIRC, shows like last week tonight (mostly static camera looking at a host) are way easier to compress than higher paced content, which (depending on previously mentioned unknown parameters) could have a large impact on the amount of artefacts. This makes it more difficult to compare different video’s uploaded at their different resolutions.

    Not to be an unfunny nitpicker (I don’t know why I’m denying this, that kinda the whole point), but all iphones do have lossless audio streaming via AirPlay. I’m assuming that you specifically meant Bluetooth streaming, but then you should’ve said so. Furthermore, normal aptx isn’t high resolution, only aptx HD and aptx adaptive are. The phone does support aptx HD as well, but once again, you could’ve said so from the start (though 3 characters more or less might make a significant difference to most memes, this one certainly wouldn’t have had that problem)


  • I’ve had good experiences with whisper.cpp (should be in the AUR). I used the large model on my GPU (3060), and it filled 11.5 out of the 12GB of vram, so you might have to settle for a lower tier model. The speed was pretty much real time on my GPU, so it might be quite a bit slower on your CPU, unless the lower tier models are also a lot faster (never tested them due to lack of necessity).

    The large model had pretty much perfect accuracy (only 5 or so mistakes in ~40 pages of transcriptions), and that was with Dutch audio recorded on a smartphone. If it can handle my pretty horrible conditions, your audio should (hopefully) be no problem to transcribe.

    “cis” and “trans” are prefixes denoting on what “side” something is. “cis” means “on this/our side”, while “trans” refers to “the other side”, for example:

    1. “Cisalpina” is how the Romans referred to their side of the Alps (modern day Italy), while “Transalpina” referred to land on the other side of the alps.
    2. There exist certain pairs of molecules with either a “cis” or “trans” prefix, depending on whether certain identical groups are on the same side or on opposite sides, respectively.

    The modern use of “cis” and “trans” is generally about gender. A cisgender person is someone whose gender identity aligns with their sex assigned at birth, while a transgender person is someone for whom that doesn’t hold true.

    In this meme, the person on the right is wearing a transgender flag for a shirt, and presumably offending the cisgender person on the left by calling them cis. The meme is making fun of the fact that some cisgender people consider “cis” an insult, when it really only is a neutral and non-offensive description.




  • To change the ownership of the files, you should only have to run sudo chown -R user:group directory. -R makes chown run recursively, so it will modify the directory and all subdirectories and files. Do note that changing the ownership to plex:plex or something similar would leave your user unable to normally modify the files. My solution to this was to add both my regular user and the plex (in my case jellyfin) user to the same group. That way both users can easily see and modify the files, as long as the group has read/write permissions (the 2nd column of rwx in ls -Al). If necessary, you can add group permissions with sudo chmod -R g+rw directory.

    On a side note: have you considered using jellyfin? It’s a completely free alternative to plex, which recently received a truly massive update with tons of new features. Some people prefer plex’ overall experience, but I’ve been running jellyfin with almost no complaints.

    Small disclaimer: I’m writing from mobile, so the commands might not be 100% correct. Run at your own risk, and NEVER POINT A CHMOD/CHOWN COMMAND AT SYSTEM DIRECTORIES LIKE / OR /USR. That’s one of the easiest ways to completely break your system.





  • Could it be that the /usr/local/bin directory doesn’t exist? If that’s the case, you’d either have to create it or replace that part of the command with some other directory in your $PATH (make sure to change both occurrences in the command if you decide to go with this latter option). Though I must add that this kind of manual install isn’t great if you want to keep track of installed apps and pending updates, since you’d have to do all of that manually too.

    People who need MS Office because once you have to collaborate with others Open/Libre/OnlyOffice won’t cut it;

    I use office almost daily, Libreoffice is fine for local editing and office online works if I have to collaborate.

    People that just installed a password manager (KeePassXC) and a browser (Firefox/Ungoogled) via flatpak only to find out that the KeePassXC app can’t communicate with the browser extension because people are “beating around the bush” on GitHub instead of fixing the issue;

    I simply installed the Bitwarden extension in Firefox and it worked flawlessly. I’m not quite sure why you would want a desktop app for a password manager (never needed this even on windows), but if you do, basically distro ships a regular Firefox package which will work just as on windows.

    Anyone who wants a simple Virtual Machine and has to go thought cumbersome installation procedures like this one just to get error messages saying virtualization isn’t enable when, in fact, it is… or trying to use GNOME Boxes and have a sub-par virtualization experience;

    4 commands doesn’t seem that cumbersome, it can quite literally be done in 30 seconds. Add to this the fact that it will be updated together with all other apps managed by you package manager, which is incomparably faster compared to windows update (or even most apps’ integrated self-updater)

    My experience with gnome boxes was also one of the most hassle-free one ever when working with virtualisation. Worked without advanced setup on a very low-end laptop (i3 4th gen, 4gb DDR3), so I’m not quite sure what would be “sub-par”.

    Designers because Adobe apps won’t run properly without having a dedicated GPU, passthrough and a some hacky way to get the image back into your main system that will cause noticeable delays;

    Adobe doesn’t have a monopoly on design software. I’m not an artist though, so it could be true that the Linux alternatives aren’t full replacements. I would like to point out that, IIRC, Linus Media Group (a company with 100+ employees) uses macs for Adobe apps; windows would constantly crash, so even here the author’s conclusion (just buy a windows key) doesn’t hold up.

    Gamers because of the reasons above plus a flat 5-15% performance hit;

    In my experience running games though proton, this is more like a 5% difference in either direction. Native games generally run significantly better for me. Though I will admit this can depend on specific hardware and games (and proton has improved a lot over the years).

    People that run old software / games because not even those will run properly on Wine;

    Wine is actually starting to support an API which Microsoft has deprecated (https://www.phoronix.com/news/Wine-8.16-Released). These apps might only work on Linux in the future, not on windows anymore. I will admit that I’m not much of a retro gamer, and other API’s might be a different story.

    Developers and sysadmins, because not everyone is using Docker and Github actions to deploy applications to some proprietary cloud solution. Finding a properly working FTP/SFTP/FTPS desktop client (similar WinSCP or Cyberduck) is an impossible task as the ones that exist fail even at basic tasks like dragging and dropping a file.

    Want to start using a new language? Just apt install the new interpreter/compiler and start right away. Want to use sftp? Just type sftp into your terminal. Also, most regular file managers just support these protocols out of the box; not having to install a separate app to use these protocols sounds like a Linux win to me. Furthermore, when developing software intended for server use, linux is simply superior due to its similarity to the environment the software will eventually run on.

    Just to make it clear, I understand that Linux is not perfect for everyone. But this article appears almost wilfully ignorant to multiple facts. It almost sounds like the author tried Linux for 2 hours, had a single issue they couldn’t resolve during that time (probably nvidia related, which is nvidia’s fault), and decided to give up and write salty articles instead of seeking help.
