  • Since games don’t have to run with more than user privileges and steam runs in flatpak, you could run them as a different user account with very limited permissions.

    That said, flatpak should be pretty secure as far as I’m aware if you make sure that permissions for the apps running are restricted appropriately. I’m not sure how restricted you can make steam and still have it work though

    You can use offline mode for steam if you’re okay with steam having internet but not games. But there’s no way to use steam entirely offline. Internet access is a fundamental part of the system they have.

    There’s also a question of what your threat model is. Like are you trying to prevent causal access of your files by games, or like a sophisticated attempt to compromise the system conveyed through a game. For the former flatpak seems sufficient. For the latter you probably need a dedicated machine. And there’s varying levels in between



  • I think something that contributes to people talking past each other here is a difference in belief in how necessary/desirable revolution/overthrow of the U.S government is. Like many of the people who I’ve talked to online, who advocate not voting and are also highly engaged, believe in revolution as the necessary alternative. Which does make sense. It’s hard to believe that the system is fundamentally genocidal and not worth working within (by voting for the lesser evil) without also believing that the solution is to overthrow that system.

    And in that case, we’re discussing the wrong thing. Like the question isn’t whether you should vote or not . it’s whether the system is worth preserving (and of course what do you do to change it. How much violence in a revolution is necessary/acceptable). Like if you believe it is worth preserving, then clearly you should vote. And if you believe it isn’t, there’s stronger case for not voting and instead working on a revolution.

    Does anyone here believe that revolution isn’t necessary and also that voting for the lesser isn’t necessary?

    The opposite is more plausible to me: believing in the necessity of revolution while also voting

    Personally I believe that revolution or its attempt is unlikely to effective and voting+activism is more effective, and also requires agreement from fewer people in order to progress on its goals. Tragically, this likely means that thousands more people will be murdered, but I don’t know what can actually be effective at stopping that.





  • Huh?? I’m using Kubuntu 24.04 right now and didn’t have to jump through these hoops. That’s weird.

    I compile them because I want to use them with my system wine, and not with proton. Proton does that stuff for you for steam games. This is for like CAD software that needs accelerated graphics. I could probably use like wine-ge and let GE compile it for me, but I’m not sure they include all the Nvapi/cuda stuff that’s needed for CAD and not gaming. If there’s an easier way to do it, I’d love to hear! Right now I’m using https://github.com/SveSop/nvidia-libs

    I’m a developer that’s been using Ubuntu distros for 20 years and never ran into such issues.

    If you’re a developer that’s comfortable with desktop software toolchains, that makes sense. (And checkinstall is wonderful for not polluting your system with random unmanaged files). But I came at this knowing like embedded c++ and Python, and there was just a lot of tools I had to learn. Like what make was and how library files are linked/found, etc. And for someone who’s not a developer at all, I imagine that this would be even harder.

    I’ve learned a lot, especially because of everyone in this thread

    I’m glad!


  • Re the flatpak issue, what you linked is just saying that flatpak won’t be a default installed program and packages provided by flatpaks won’t be officially supported by Ubuntu support as of 23.03. I don’t think this effects your use of Ubuntu in any way. If you want to use flatpaks, just install the program. It will still be packaged in the Ubuntu repositories. 23.04 was over a year ago. I still use flatpak without a problem on my kubuntu 24.04 system. It’s just a one time thing to do sudo apt-get install flatpak and maybe a second package for KDE’s flatpak packagekit back end and it’s like canonical never made that decision.

    The push of snaps instead of debs is a bit more concerning because it removes the deb as an option in the official repositories. But as of right now I think only Mozilla software has this happening? If your timeline is 5-10 years though, this may be more of an issue depending on how hard canonical pushes snaps and how large their downsides remain


  • All those patches seem like nice things to have, but are more focused on adding hardware support and working around bugs in software/other people’s implementations. If you have one of the effected GPUs/games/etc, then those patches probably make a huge difference, but I’d guess there won’t be noticeable frame rate differences on most systems. I have not tested this claim though, so maybe something on there makes a big difference. What’s nice is all the packaging stuff they’ve done to make setting things up correctly easily, not necessarily most of the changes themselves. Like on my system I compile dxvk and various wine nvidia libs myself since Ubuntu doesn’t package them. And it’s easy to screw that up/it requires some knowledge of compiling things

    Reading your update, I’d still choose whatever distro packages the software you want with the versions/freshness you need. If you’re willing to tweak things, then the performance stuff can be done yourself pretty easily (unless you have broken hardware that isn’t well supported by the mainline kernel), but packaging things/compiling software that isn’t in the repositories is a huge pain. I think this is one of the reasons people choose arch even with its need to stay on top of updates. Is that the AUR means that you don’t have to figure out how to build software that the distribution managers didn’t package. Ubuntu’s PPAs aren’t great (though I don’t have personal arch experience to compare with)


  • I’m not sure what performance improvements you’re talking about. As far as I’m aware, the difference between distros on performance is extremely minimal. What does matter is how up to date the DE is in the distribution provided package. For example, I wanted some nvidia+Wayland improvements that were only in kwin 6.1, and so I switched from kubuntu to neon in order to get them (and also definitely sacrificed some stability since more broken packages/combinations get pushed to users than in base ubuntu). It’s also possible that the kernel version might matter in some cases, but I haven’t run into this personally.

    I think the main differences between distros is how apps are packaged and the defaults provided, and if you’re most comfortable with apt based systems, I’m not sure what benefit there’s going to be to switching (other than the joy in tinkering and learning something new, which can be fun in its own right).

    For some users less experienced with linux, the initial effort required to setup Ubuntu for gaming (installing graphics drivers/possibly setting kernel options, etc) might push someone toward a distribution that removes that barrier, but the end state is going to be basically identical to whatever you’ve setup yourself.

    The choice between distributions is probably more ‘what do I want the process to getting to my desired end state to be like’ and less ‘how do I want the computer to run’.



  • I’ve setup okular signing and it worked, but I believe it was with a mime certificate tied to my email (and not pgp keys). If you want I can try to figure out exactly what I did to make it work.

    Briefly off the top of my head, I believe it was

    1. Getting a mime certificate for my email from an authority that provides them. There’s one Italian company that will do this for any email for free.
    2. Converting the mime certificate to some other format
    3. Importing the certificate to Thunderbird’s (or maybe it was Firefox’s) certificate store (and as a sidequest setting up Thunderbird to sign email with that certificate
    4. Telling Okular to use the Thunderbird/Firefox certificate store as the place to find certificates

    I can’t remember if there was a way to do this with pgp certificates easily


  • I’d be surprised if it was significantly less. A comparable 70 billion parameter model from llama requires about 120GB to store. Supposedly the largest current chatgpt goes up to 170 billion parameters, which would take a couple hundred GB to store. There are ways to tradeoff some accuracy in order to save a bunch of space, but you’re not going to get it under tens of GB.

    These models really are going through that many Gb of parameters once for every word in the output. GPUs and tensor processors are crazy fast. For comparison, think about how much data a GPU generates for 4k60 video display. Its like 1GB per second. And the recommended memory speed required to generate that image is like 400GB per second. Crazy fast.




  • Is the bad side of the seam where it stops or where it starts printing the outer wall? I assume it’s where it stops and then it cross the wall to form the infill?

    To add to the PA questions, are you sure that your PA setting actually are changing anything?

    What printer is this and what firmware?

    Does a spiral mode print work fine?

    What if you print the part significantly slower (to rule out rigidity/acceleration issues)


  • That make sense. I would use tags like that:

    • Flickr Published

    • year roundup/2022

    • type/Landscapes

    • type/Portraits

    • events/trips/Zion 2022

    • content/food

    • content/animals

    I actually do event level as my on-disk sorting. And then tag for stuff that’s not that. But I think it would work pretty well to do the event sorting under tags as well.

    Then I rate my favorite photos, usually using the green approved, not stars. But stars would work too. Then if you want to find say, favorite landscapes, the digikam interface makes it really easy to do so.

    I’m not sure if you can select what tags get written into the image, but if you can, you might be able to exclude certain parts of the hierarchy, and only include content/ or type/ subhierarchies
