Linux for Kids?
  • If the child is really young, check out the sugar desktop environment. There is an official distro from sugarlabs and there is also a fedora spin (fedora soas)
    If the computer should be a little more functional, the GNOME desktop or the Deepin desktop are good options imo

  • Which is the most active Pixelfied instance?
  • As far as I know, no. But you can from mastodon, pleroma, or other similar microblogging oriented software

  • Which is the most active Pixelfied instance?
  • Although the most active instance by far is pixelfed.social, that shouldn't be relevant as you can interact with any pixelfed or mastodon account/posts no matter the server you join. So, you could join any pixelfed instance and follow the mastodon.art (most active multimedia instance) users, for example

  • Run command as not-root
  • @elscallr I agree about the instance configuration, fixing that is the real solution
    My question was not about running something as another user, but about hiding the superadmin privileges from a single command I'd execute without switching users. However it is clear that something like that doesn't exist so I'll do the right thing and set everything to work with a new user

  • Run command as not-root
  • @Rustmilian Just did that and that is exactly what I needed, but in this case it didn't work. In this page https://docs.aws.amazon.com/systems-manager/latest/userguide/session-manager-prerequisites.html they explain that what the manager does is creating another root account in the instance, and that new account is the one that can disable its own permissions. So, I ended up with the same problem of having to configure everything for the new user. However I'm done with the laziness and I'm gonna do it lol, everyone else pointed out that not having a regular user is a security issue and they are right. If I had configured the instance from the beginning with the SSM, I could have skipped all that work, but the reality is that I have to do it
    After I'm done configuring everything, I think I'll set up the rest of the instances to work with the SSM so that I don't have to go through all that again
    Thanks for the help!

  • Run command as not-root
  • @Oisteink yep, that seems the right thing to do. Honestly, most of the real problem was lazyness to reconfigure everything, and that's why I published the question. But now I'm convinced that that's the only way lol
    Thanks for the help!

  • Run command as not-root
  • @astraeus yep, completely agree on the security issues, that is a mistake that should be fixed. But for the moment I confirmed that root is the only user, and every file and program in the instance can only be used by root (I just created a new user and tried to run the command with su -c but got a lot of permission denials and command not found)
    If I could hide or disable my own sudo permissions that would save me a lot of work, but I'm starting to think that something like that doesn't exist 🙁

  • Run command as not-root
  • @Oisteink in another comment (https://social.vivaldi.net/users/nirogu/statuses/111342629815373353) I explained why I'd prefer not to create another user, as it would require a lot of work to configure everything again for that command to work (it's a big process). I was thinking of hiding my sudo permissions from the program or something like that, if possible, because many things in the instance are only configured to be used with the root user, even if they don't require sudo. Anyway, I'm seeing that it might not be possible so creating a new user could be the only option 🙁

  • Run command as not-root
  • @Rustmilian yeah, already tried it. The problem is that all of the apps in the instance are only installed for the root user (e.g. python and all it's libraries. So, when I use su -c all I get is a lot of command not found messages that would take a lot to solve. Besides I expect a lot more problems when the command needs access to some files and some processes (like a sql database) that would require me to do a lot of stuff to grant permissions to the new user. That would eventually work but given the work it requires I thought that some kind of "anti sudo" command or something like that could exist so I can still be the root user but pretend I am not a superadmin

  • Run command as not-root
  • Forgot to mention that creating a new user brings a lot of problems because of how that machine is configured and all the tools that would need to be added the new user's permission. In theory it would eventually work after some time working on it, but I'd like to know if there's a way to do it without creating users (or if it's impossible, so I can just go on with that only option)
    @linux

  • Run command as not-root
  • @astray yeah, that could be an option, but if more users exist in that machine then other processes might fail as that instance is part of a bigger cluster that has several processes running. It might not be a big deal, but checking that may still need some work. I'd prefer a way to do it without creating new users, if it exists

    Run command as not-root

    Hi everyone

    At work, I have to run a command in an AWS instance. In that particular instance only exists the root user. The command should not be executed with root privileges (it executes mpirun, which is not recommended to run as sudo or the machine might break), so I was wondering if there is a way to block or disable the sudo privileges while the command is running. As mentioned, the only user existing there is root, so I suppose "sudo -u" is not an option.

    Does anyone know how to do it? Thanks in advance!

    FOSS Microsoft Office for Linux
  • If you didn't like LibreOffice user experience, you should try softmaker FreeOffice. It's an open source office suite practically identical to Microsoft office, and with almost every feature you should ever need. However I stand with the rest of the comments and think you should get used to LibreOffice if you have the time

  • PaLI-3 Vision Language Models: Smaller, Faster, Stronger
  • Impressive results! Only wished they had shared some code or any way to replicate the experiments easily

  • Very well explained! Especially given how difficult RL can be sometimes

  • Problem with WiFi driver in arch linux
  • @Link @linux Yep, writing from Tusky right now. The fediverse is great :)

  • Problem with WiFi driver in arch linux
  • @Rustmilian @linux Yeah, it's close to impossible to find documentation on what to do here. I'm trying to find out how is it that Fedora works well with the same hardware, and even considering changing the card itself, but for the moment at least my connection is much more stable after setting the iwlwifi.conf file
    Once again, thank you for your help!

  • Problem with WiFi driver in arch linux
  • @Link @linux Yeah the kernel changes nothing, I might have to change to intel because I dont know what else to do at software level
    About the @ , I'm using my mastodon account to write all these posts and they are added automatically. Besides thats the best way for the posts I write in mastodon to appear as comments in lemmy clients. If they look weird to you it might be activitypub compatibility bugs but nothing too important :)

  • EndeavourOS Moving to KDE Plasma by Default
  • Great news. Seems that most of the community uses KDE anyway, so this should make things faster for most installations

  • Problem with WiFi driver in arch linux
  • @Link @linux Yeah, I'm thinking that that could be the way. I've already had a lot of progress maintaining the connection by configuring iwlwifi but it is still way slower than it should

    Problem with WiFi driver in arch linux

    Hi everyone

    I've been trying to solve a problem with my arch (endeavour) instalation and wanted to know if anyone here can help

    Everything is working well, excepting the WiFi connection. It is extremely slow, sometimes disconnecting from the network, and in the task bar, the WiFi icon shows that the signal strength is weak, although the router is in the same room. Switching between r8168 and r8169 as recommended doesnt work. Any ideas?
