  • (SOLVED) I need help with networking for VirtualBox guests running on Windows hosts.

    Jump

  • Sounds like a networking exercise on its own.

    Do the attempted pings show up on the wire? (Switch LEDs, network card activity light.)

    Does broadcast work? (Watch if it is received with tcpdump -n on both Linux VMs, and Wireshark on the Windows hosts, while doing ping -b 10.0.0.255. Or trigger a broadcast ARP by ping-ing a non-existing IP in the same network. Those should go through all bridge and switch devices, independent of IPs and routing setup.)

    I think you need four distinct MAC addresses for this setup, are they all different?

    The network card/driver is filtering received unicast by MAC. I'm sure something should set up the filters correctly, but maybe it went wrong, or there is a bug in the driver. Wireshark on Windows should be able to enable promiscuous mode, which disables the filter.

    Side note: I don't think you need a crossover cable. Auto-crossover should just work these days.

    At work I map a USB Ethernet device into my Linux VM when I do anything networking, exactly to avoid those kind of "is it Windows?" questions. Also, I can then check the Ethernet link at the lowest level using Linux tools like ip link or mii-tool or ethtool.

    I'm using VMWare for this, which I cannot recommend any more. (It used to be good for this, but gut much worse in recent years.) I think vanilla VirtualBox doesn't allow to map USB devices.

  • France will replace Microsoft Teams, Google Meet, Zoom, Webex and others with its own sovereign video conferencing application "Visio" for public officials

    Jump

  • Having used both Jitsi and LiveKit, I get it. Jitsi is great if you use it as it is, but if you want to integrate video conferencing into your own solution and customize everything, LiveKit is the logical choice. (I think it is also much newer then Jitsi, which used to be the only choice.)

    If they wanted to integrate a finished product, I would expect them to use Matrix over Jitsi, because it seems to have seen some use in France already.

    Also, I think Matrix integrated LiveKit for video over their existing Jitsi integration, so... the ecosystem seems to flock around LiveKit anyway. So maybe the'll contribute to LiveKit if they find issues with it, and everyone benefits from that.

  • Best CAD software for open source hardware design

    Jump

  • Blender user here. I think you got it right, and FreeCAD is probably your best bet. Maybe give it a second chance.

    OpenSCAD is in a different category, it's more like a coding tool or software library. There are other options if you're into that, e.g. build123d.

    I can't use FreeCAD myself, but then I don't have a mechanical engineering background, so I was also learning the basic CAD workflow when I tried it. At work my colleagues (who occasionally 3D print some part) seem happy with it, and keep telling me I should use a proper CAD to design parts.

    Personally I'm happy with Blender, using it for my hobby 3D print designs. Most have some playful/artistic touch in addition to being functional, and Blender shines at that. But you totally can do a parametric design in Blender natively, it just won't be a CAD workflow with the constraint solver you expect. The CAD plugins I have tried felt experimental. The native tools are very solid, and Blender is very polished and mature. But it is targeting expert users (including teams, since you asked about that). Learning Blender is an investment, it took me a long time. If you are still curious, look for a video demo/tutorial of someone designing a 3D part in Blender. Don't just open it and expect to be able to do stuff, you will not figure out on your own which tools/modifiers you should use.

    (And since you didn't say what kind of CAD, also check out KiCad if you are doing PCBs!)

  • Well the problem is trying to attach the concept of "done" to a bitstream. You can release it, but then the release is "done", not the software. You can evaluate software only in a specific cultural context, where it can be useful or not. Software is more similar to a law than to a fabricated pencil. Laws are updated and re-interpreted as the culture around them evolves, and they are "done" when the culture is done.

    I like this quote:

    The more we see creative software engineering as monotonous ticket crunching instead of learning and experimentation, the more we compare producing software to building houses. With that analogy, you can only go wrong. (Niko Heikkilä)

    In other words, a factory product is "done" when it passes QA. You can try to apply the same productivity mentality to software (or to laws) but it just doesn't make sense, because those are instructions how to do things, and not products to be consumed. It's not a factory product, it's a living cultural process.

  • Easy: Most software is done when nobody uses it any more.

    If the code you wrote 10 years ago still isn't quite done yet, you should celebrate. If someone still cares enough to consider it broken, or can think of improvements, it means that it is useful. In contrast to: finished and done with.

  • F-Droid Basic 2.0 alpha released

    Jump

  • I see where this comes from, but it's funny because F-Droid is the very last place where I expect this to happen. Right after hell freezes over. Imagine them listing their own app with an anti-feature from their list: https://f-droid.org/docs/Anti-Features/

  • Do we need more users ?

    Jump

  • Yes. I'm here for the long tail, the niche communities. And what do I see? Not enough photos of houseplants! Come on, you must have some too. And to add to the list, !books@lemmy.world looks nice.

  • I'm still proud of my rendering of the logistic map. It was mostly just to learn more Rust, but it rendered this beatuiful picture with relatively little code. And mostly by accident, I didn't know I would get those cool shadows!
