  • Can somebody explain the graphics stack? Vulkan, OpenGL, Magma, DirectX, SDL, Metal, Mesa, ... wat?

    Jump

  • Thanks, this answers the questions I asked another commentor 😅 Now I have to ask if Mesa is an implementation of OpenGL, what is an implementation of Vulkan? Or is the reference implementation of Vulkan also called "Vulkan" ?

    Edit: alright @who@feddit.org answered the question.

  • Thank you. I'll ask questions here, but might find out more while reading the other answers.

    So, SDL provides a window with an OpenGL surface. What is OpenGL? Is it an API spec that can have multiple implementations like the opensource implementation that is Mesa? Is DirectX 3D the same just with a proprietary implementation? @Kissaki@programming.dev answered this.

    And when you say "Vulkan is multi-threaded", does that mean that the implementation uses instructions for drivers that target a multiple GPU cores? I would have expected the multi-threaded or parallelism aspect to be handled by the driver, not the driver client (in this case Vulkan or Mesa/OpenGL).

  • It really could be more if the linux user community could agree on things and stop gatekeeping - which seems to be the only thing most online active linux users can agree on "ermagerd eternal september" 🙄

    As Windows 10 end-of-support looms, IT faces a painful choice

    Jump

  • Isn't that the same for an upgrade to Windows 11? You don't "just" upgrade to a new OS or OS version without checking whether everything will work. What kind of an "IT leader" would you be?

    I'd say if you aren't looking at alternatives and testing them to reduce costs and future turmoil like this, you aren't doing your job. Whether the outcome is sticking to Windows 10 and paying the fee, upgrading to Windows 11, or finding a Linux distribution for your environment, at least do the legwork of investigating.

  • The Stop Killing Games movement is great because it brought this kind of thing to light. I just hope it will succeed and not just fizzle out after gamers think getting 1M signatures is the end of the road. There is a long battle ahead.

  • UK firm achieves first commercial tritium breakthrough for fusion fuel

    Jump

  • The ability to generate tritium within the reactor is crucial. A sustainable fusion energy system needs to produce more fuel than it consumes

    I clearly don't understand the fusion process. Deuterium is used to fuse and create tritium?

    The reactor core also features an electron-screened environment. This design reduces the energy needed to overcome the Coulomb barrier between particles, which lowers required fusion temperatures by several million degrees and allows for higher performance in a compact size.

    What's this "electron screened environment" they are talking about? They can't purge all electrons from molecules when they enter can they? That would make the molecule instable. But it sounds like they are doing something similar in order to reduce the temperature required for fusion.

  • GitLab abandons federation plans!

    Jump

  • The comparisons you're making are off base and it feels like you're mocking something you don't understand, while doing so with a lot of confidence. I'd suggest you either read an article, watch a video, or read the ActivityPub spec's intro. It isn't long and should help you understand the basics. Then you can move on the ForgeFed spec which is the ActivityPub extension for source forges. And you can always ask an LLM to summarise it for you if you really don't understand.

  • GitLab abandons federation plans!

    Jump

  • Git is already inherently distributed and automagically mirroring to other remotes is generally like three lines in any CI syntax (and there is probably a precommit hook for it too).

    Git is, but what about everything else? When you clone a project on gitlab or github, does it come with all the issues, discussions, MRs, and so on?

    I can see a LOT of security issues with not having a centralized source of truth on what the commit hashes should be and so forth.

    That's what signed commits are for. Also, pull/merge requests and issues are sent to the origin instance, just like in the fediverse. Like now, you made a comment on a post on Fediverse@lemmy.world through your instance lemmy.zip. The same would happen with your comments, pull/merge requests, issue reports, and so on. There's no need for a "central authority".

  • LKML: The end boss of kernel development

    Contributing to Linux was my first time interacting with a mailing list, at least for the purpose of sharing and reviewing code. I thoroughly hated the entire process. I tried in vain to write about my experience in a constructive manner, but it always turned into an unhinged rant, so I gave up. In summary, I think that sending and reviewing patches via email is exactly as insane as it sounds.

    That's the worst part but kconfig doesn't sound much better. Even if I had time, I wouldn't try contributing to the kernel for those 2 reasons alone.

    It is great that he got to the point he is now. Kudos for pervering.

  • What's your "Oh fuck, that actually worked!" Linux moment that made you feel like a wizard?

  • And now we have a new streaming service 🤔 Really nice.

    I was thinking that by now, we should have enough bandwidth to stream webcams straight to each other without HLS or WebRTP or whatever. Just make the device available over a port or, as you did, cat it to another PC and voilà. Actually, why don't we stream raw camera feeds?
