  • I think it would not have a shape, or would rather be a zero dimensional point. For it to be any shape, it would have to have features, but you’ve already defined this as the fundamentally smallest ‘thing’ so it can’t have any features smaller than itself. But you could also probably convince me that it’s a sphere. I’m not sure if mathematicians consider a sphere of infinitesimal radius to still be a sphere or not, but treating it as infinitesimal kinda makes sense to me even if it’s actually finitely small (the Planck length?)

    A more interesting question to me is, assuming positions in space are discrete, which I’m not sure follows from saying there’s a smallest possible object, how are those ‘voxels’ arranged? I don’t think that’s necessarily equivalent to asking what the shape of the smallest object would be. Pixels on a screen are in a rectangular grid, but the actual elements are circles in some types of screens.

    There are a number of shapes besides cubes that can fill 3D space, but do the voxels even have to all be the same shape? Are we even looking for a 3D tiling, or could it be 4D in spacetime, or even higher dimension if it turns out the universe has more than 4 dimensions? Does it have to tile at all, or could it be entirely irregular while still being discrete? Is there any conceivable experiment that could prove any of these things, or is it unknowable?



  • Within the Milky Way a polar (cylindrical) coordinate system makes more sense than Cartesian - there’s an axis of rotation to define the center and ‘up/down’ directions. Zero degrees is arbitrary but a line from the galactic center to Sol, projected onto the galactic plane, would be an obvious choice as a sort of galactic prime meridian. ‘North’ and ‘south’ don’t really map to a roughly disc shaped galaxy - you’d use distance from center, angle, and ‘elevation’.

    On an intergalactic scale, the center of our own galaxy is probably still the obvious choice for a center point. We could use the same axis and meridian - I don’t think the rotation of our galaxy matters on any human timescale, and on the time scales where it does matter, everything is moving relative to each other so coordinates already aren’t ‘fixed’. I’d use a spherical coordinate system instead of cylindrical for intergalactic coordinates, since things are not roughly in a plane anymore.

    If you want a fixed coordinate you’d have to include a time dimension, and as the zero point for time I propose the Unix epoch. Not because it makes any sense but because it’s extremely funny to imagine computer systems in the year 10000 still relying on that legacy decision. Though special relativity makes ‘point in time’ rather complex as well - I don’t know enough to know what you’d actually need to make that work.

    Of course we already have such coordinate systems for astronomy if you want to know the ‘real’ answer, one of them is pretty close to what I just came up with: https://en.wikipedia.org/wiki/Astronomical_coordinate_systems


  • Mullvad is a great VPN though, if Mozilla branding gets more people to use it instead of any of the scummy ones that are everywhere these days, it’s a good thing for privacy, the open web, etc. - the causes Mozilla is supposed to represent. It’s way better aligned with their goals than a lot of the other non-browser stuff they’ve been doing. I’d rather see them profit from that than from nonsense like ‘sponsored stories’ on the homepage.

    Drop shipping is a great analogy though - branding and marketing is the only thing Mozilla is bringing to the table as far as I’m aware.


  • During the Reddit API stuff, same as most of the folks here. I tried kbin first but lack of an API or mobile app at the time pushed me to Lemmy instead.

    I eventually caved and started using the official Reddit app, but I still check here as well - less content but I like the vibes here. Reddit hasn’t been the same since the protests - might just be bias but I feel like ‘brain drain’ was real and quality discussions over there are a little less frequent than before.


  • I was thinking the photolithography process might be almost as important as the transistor itself. Without the ability to miniaturize transistors and create integrated circuits, we wouldn’t have anywhere near the level of technology we can build now. A computer made of discrete transistors would be way more efficient, reliable, and cheaper than one made with vacuum tubes, but would still be very limited. There are things you fundamentally couldn’t do with even thousands of discrete transistors that became possible once we were able to scale to millions and now billions.

    My first VPS was for a Minecraft server so I named it cobblestone. I’ve kept using Minecraft related names for all my machines since then, and I try to pick ones that are at least vaguely related to the function or appearance of the machine. For example my cluster has brute for the master and piglin01-piglin04 for the workers, but those are the only ones I’ve numbered.

    The exception is my two Klipper RPi’s, one is octopi since that’s what it originally ran, and the other is named after the model of the printer. For some reason I never named my printers.

    I probably wouldn’t use a naming scheme like this for production servers though - I’d either go with functional hostnames or something like the periodic table which you can pick from arbitrarily. My home servers and clients aren’t cattle though, so I like having a little personality to the names there.





  • +1 to this! I bought the same chair from them a couple years ago, and as a remote worker it’s been worth every cent. Oddly enough I had the Leap v1 as a previous job and hated it, but the v2 has been great for me. I found the armrests a bit uncomfortable but some cheap memory foam covers solved that.


  • I use Debian on my servers, Arch on my laptop and desktop. Different tools for different jobs. I tried Debian on my laptop a few years ago but it wasn’t a good fit for me - my hardware was too new for the stable kernel, and the Wayland/wlroots stuff was too far behind. As a server though, especially since I’m mostly running Podman containers, stable and slow-updating is great! I use unattended-upgrades and haven’t had a problem yet.

    I haven’t spent much time with Fedora but I’d probably like it as a desktop OS - fairly fast updates, and sticks pretty close to upstream without a ton of custom theming for example. I would miss the AUR, but Flatpak covers a lot of what I need, and Distrobox could handle anything else.



  • I’m not either (besides Minecraft and such) so my personal experience with Linux gaming has been pretty good. There’s some jank with needing to pick the right Proton version and adding command line options, but I’m not sure it’s any worse than Windows - I’ve had to reinstall my graphics drivers way too many times. But there’s a large portion of gamers that almost exclusively play the big multiplayer games, and Linux is definitely not ready for that group.


  • It’s pretty good for single player games on Steam but a lot of multiplayer games use anti-cheat that doesn’t work on Linux, and some launchers don’t work well. And of course if you use Game Pass for PC you’re out of luck entirely. Most VR headsets also won’t work on Linux.

    So it really depends what kind of games you play. It’s kind of similar to the Adobe situation. I suspect most gamers will have at least one deal-breaker that forces them to keep at least a dual-boot around. But many people could use Linux most of the time, including for games, and that’s already pretty exciting for Linux fans.


  • Weird esoteric issues happen on Windows too. I had a bug where I couldn’t create a new folder from Windows Explorer, which I never figured out and didn’t resolve itself with reboots or even Windows updates. I probably could have spent a half day tracking it down and fixing it, but someone less tech savvy would probably have had to reinstall Windows. Instead I just popped a terminal and used mkdir whenever I needed a new folder until I upgraded to Windows 11 and that resolved it.

    Point is, computers just suck sometimes regardless of what software they run. Or I’m just a magnet for ridiculous arcane bugs, you decide.

    This might come across as Linux fanboyism but I currently have Linux, Windows, macOS, iPadOS, Android, and FreeBSD all running on various devices around my house and they all suck in their own unique ways.




  • Backups. Cloud services like Backblaze B2 are so cheap for the durability they offer, it just doesn’t make sense for me to roll my own offsite solution with a Raspberry Pi at my parents’ house or something. Restic encrypts everything before it leaves my machine.

    Password manager- it’s too important and it’s the thing that has to work for me to recover when I break something else. I’m happy to support Bitwarden with a few bucks a year.

    Email- again, it’s mission critical and I have a habit of tinkering with things and breaking them. And it’s just no fun. The less I need to think about email, the happier I am.
