  • In the BBS days before the internet really, my dad told me not to use my full name online. So I used martinxyz. This was getting old soon, so I contracted it to maxy. Some people now call me Max online, which I find kind of funny. I’m no longer trying to hide the link to my full name, I just don’t actively mention it because it really doesn’t matter. And when I want to cut the link I use pwgen.



  • 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.



  • 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.

    The only thing I noticed is that the size of the pot has a huge effect on its growth.

    Apart from that, I have no idea what I’m doing right. It may be the sunny, south-facing window. I have harvested several pineapple fruits over the years. They seem to be absolutely unstoppable and unkillable and predictable in their growth here. They don’t care about seasons (it’s snowing!). The only time I managed to kill one is when I put the pot outside in summer - it went bad in just three days.
