Has anyone here built a Beowulf Cluster?
  • Same. I forgot all about it before this post.

    It was almost 20 years ago when I built a cluster using around 40 desktop computers for purely academic purposes in our lab. Since then I never heard of it again even though I was working with HPC for a few years.

  • Still is quite remarkable how small the pop culture impact of the other Avatar is
  • I'll bite. What is the deal with Bluey? I watched the first episode to see what all the fuzz is about and it looks like a fine show for smaller children, but what else is it? There doesn't seem to be anything wrong with it, but I was expecting something different for all the hype.

  • Aren't all commercial plane turbine engines high bypass turbofans? (excluding turboprop)

    Serious question, because I assumed that's how they all worked, but this sounds like it is special or in spite of and it got me wondering.

  • Linux community throught history
  • The problem is always having the bad option being enabled by default. Not even the ads are the biggest problem. I didn't even mention their current ads in the terminal. The problem is the same Microsoft is having now, that your keyboard input gets sent to an untrustworthy third party.

    Your comment got cut off. If you wanted to dispute the paid paid claim. It is about Ubuntu Pro, that's literally all what the basic tier is. We recently even had the case where a patch with a highish CVE rating was only available to subscribers of the service. We also verified that the same patch was already available on Debian. Even without my anecdote it should be obvious why it is bad.

  • Linux community throught history
  • Emphasis on it was. It started to go downhill with Amazon integration and now we have paid security updates. They are holding back developed and available security packages for their OS!

    There is no way to still recommend Ubuntu. No need to even talk about the other questionable decisions like snap.

  • Just moved to Linux: a follow up
  • Not the person above, but if it is an issue you ever run into you are doing it "wrong". Not really, but let me explain.

    Having it on a separate partition has a few advantages like different mount flags (e.g. noexec), easier backup management (especially snapshots) and some other benefits like using your home for a new installation (like OP wants to) or it prevents some critical failures in case you accidentally fill it up (e.g. partial writes or services cannot start).

    I often cannot decide on specific mount sizes either, because requirements may change depending on what you do. Hence I would just stick with some reasonable defaults for the installation and use some form of volume manager instead. If you want to use ext4, xfs etc I would recommend using LVM as it gives you a lot of freedom (resizing of volumes, snapshots and adding additional drives, mixed RAID modes etc) or there are btrfs, zfs or bcachefs to name the most common file systems which implement their own idea of storage pools and volumes.

    Never should you need to resize a partition, there are more modern approaches. Create a single partition (+ a small EFI partition somewhere) and never bother with partitions ever again. The (performance) overhead is negligible and it gives so many additional benefits I didn't even mention. Your complaint is a solved problem.

  • Weekly “What are you playing” Thread || Week of December 17th
  • I just finished Witch Spring R the other day. I think I managed to see almost everything the game has to offer. A very simple and mostly light hearted game.

    Now I just started a playthrough of Cassette Beasts. I am intrigued by the story.

  • Idea / Question about tiling window managers
  • I think mixing horizontal and vertical is impractical, because it will mess up the whole layout once you resize a single window, but on one axis the concept is actually sound. There exists PaperWM for gnome 3 which is basically just this.

  • Just a PSA
  • sudo is not simply a tool to give admin privileges, but a tool to manage elevated permissions or run commands in a different users context.

    These things become a lot more relevant once you use the tools professionally. In a well configured system you are only allowed to run the things you are explicitly allowed.

    To be completely honest sudo is basically pointless in a single user context. There is almost no reason to even have it installed. It makes dealing with different environments easier though.

    Anyway as I said it does not matter in many cases if you are the systems administrator. On the other hand there is also no benefit in getting used to bad practices in case you have to unlearn them later.

    One more thing: what you suggest with chroot is one of the very reasons why you should not do that. You might have handed over the keys to break out of chroot. It is a well known vector which boils down to never run anything as root in a chroot environment.

  • Just a PSA
  • sudoedit opens the editor as your user and just writes the file as root. For a single user who is also admin on the system this does not matter in many cases.

    In a multi user context you can easily escape your editor and run a shell which allows a non admin user to escalate their privileges. So from a security implementation standpoint this must exist and it does for this reason.

    Of course this also prevents some mistakes from happening and a bad plugin cannot destroy your whole system easily and so on. It boils down to good practice.

  • Autofahrende immer Vorbild für alle anderen 🫶
  • Würde Autofahrer definitiv ganz oben sehen. Rücksichtslos sind alle, aber dort ist es am schlimmsten.

    Klar fahren die Roller und Fahrräder an Orten wo die es nicht dürfen, aber selten rege ich mich deswegen auf.

    Ich rege mich aber drüber auf, wenn ich am Zebrastreifen vom Auto fast umgefahren werde, wenn das Auto viel zu schnell durch die 30er fährt und mich fast dabei mitnimmt. Dann der Lärm, der Gestank und vor allem das Gehupe was teilweise an Körperverletzung grenzt.

  • Keyboard shortcut for accessing the Steam menu

    Hello everyone!

    Today I bought a mouse and keyboard for the couch to play some games which are not made for controllers. Unfortunately I can't figure out how to access the Steam menu once I am in-game. The desktop overlay combination does not seem to work (shift + tab) and I don't know what else to try as I don't have anything resembling the PlayStation or Xbox buttons like on my controllers.

    Desktop mode itself is unfortunately unusable as Steam ignores the scaling configuration and text is unreadable small on the TV. I just bring this up, because I suspect the overlay combination would work here.

    Does anyone know what keys to press in normal big picture esque mode to open any of the Steam menus while in-game?

    Thank you!
