  • I just am not sold that there’s enough of a market, not with the current games and current prices.

    There are several different types of HMDs out there. I haven’t seen anyone really break them up into classes, but if I were to take a stab at it:

    • VR gaming googles. These focus on providing an expansive image that fills the peripheral vision, and cut one off from the world. The Valve Index would be an example.

    • AR goggles. I personally don’t like the term. It’s not that augmented reality isn’t a real thing, but that we don’t really have the software out there to do AR things, and so while theoretically these could be used for augmented reality, that’s not their actual, 2026 use case. But, since the industry uses it, I will. These tend to display an image covering part of one’s visual field which one can see around and maybe through. Xreal’s offerings are an example.

    • HUD glasses. These have a much more limited display, or maybe none at all. These are aimed at letting one record what one is looking at less-obtrusively, maybe throw up notifications from a phone silently, things like the Ray-Ban Meta.

    • Movie-viewers. These things are designed around isolation, but don’t need head-tracking. They may be fine with relatively-low resolution or sharpness. A Royole Moon, for example.

    For me, the most-exciting prospect for HMDs is the idea of a monitor replacement. That is, I’d be most-interested in something that does basically what my existing displays do, but in a lower-power, more-portable, more-private form. If it can also do VR, that’d be frosting on the cake, but I’m really principally interested in something that can be a traditional monitor, but better.

    For me, at least, none of the use cases for the above classes of HMDs are super-compelling.

    For movie-viewing. It just isn’t that often that I feel that I need more isolation than I can already get to watch movies. A computer monitor in a dark room is just fine. I can also put things on a TV screen or a projector that I already have sitting around and I generally don’t bother to turn on. If I want to block out outside sound more, I might put on headphones, but I just don’t need more than that. Maybe for someone who is required to be in noisy, bright environments or something, but it just isn’t a real need for me.

    For HUD glasses, I don’t really have a need for more notifications in my field of vision — I don’t need to give my phone a HUD.

    AR could be interesting if the augmented reality software library actually existed, but in 2026, it really doesn’t. Today, AR glasses are mostly used, as best I can tell, as an attempt at a monitor replacement, but the angular pixel density on them is poor compared to conventional displays. Like, in terms of the actual data that I can shove into my eyeballs in the center of my visual field, which is what matters for things like text, I’m better off with conventional monitors in 2026.

    VR gaming could be interesting, but the benefits just aren’t that massive for the games that I play. You get a wider field of view than a traditional display offers, the ability to use your head as an input for camera control. There are some genres that I think that it works well with today, like flight sims. If you were a really serious flight-simmer, I could see it making sense. But most genres just don’t benefit that much from it. Yeah, okay, you can play Tetris Effect: Connected in VR, but it doesn’t really change the game all that much.

    A lot of the VR-enabled titles out there are not (understandably, given the size of the market) really principally aimed at taking advantage of the goggles. You’re basically getting a port of a game aimed at probably a keyboard and mouse, with some tradeoffs.

    And for VR, one has to deal with more setup time, software and hardware issues, and the cost. I’m not terribly price sensitive on gaming compared to most, but if I’m getting a peripheral for, oh, say, $1k, I have to ask how seriously I’m going to play any of the games that I’m buying this hardware for. I have a HOTAS system with flight pedals; it mostly just gathers dust, because I don’t play many WW2 flight sims these days, and the flight sims out there today are mostly designed around thumbsticks. I don’t need to accumulate more dust-collectors like that. And with VR the hardware ages out pretty quickly. I can buy a conventional monitor today and it’ll still be more-or-less competitive for most uses probably ten or twenty years down the line. VR goggles? Not so much.

    At least for me, the main things that I think that I’d actually get some good out of VR goggles on:

    • Vertical-orientation games. My current monitors are landscape aspect ratio, and don’t support rotating (though I imagine that there might be someone that makes a rotating VESA mount pivot, and I could probably use wlr-randr to make Wayland change the display orientation manually) Some games in the past in arcades had something like a 3:4 portrait mode aspect ratio. If you’re playing one of those, you could maybe get some extra vertical space. But unless I need the resolution or portability, I can likely achieve something like that by just moving my monitor closer while playing such a game.

    • Pinball sims, for the same reason.

    • There are a couple of VR-only games that I’d probably like to play (none very new).

    • Flight sims. I’m not really a super-hardcore flight simmer. But, sure, for WW2 flight sims or something like Elite: Dangerous, it’s probably nice.

    • I’d get a little more immersiveness out of some games that are VR-optional.

    But…that’s just not that overwhelming a set of benefits to me.

    Now, I am not everyone. Maybe other people value other things. And I do think that it’s possible to have a “killer app” for VR, some new game that really takes advantage of VR and is so utterly compelling that people feel that they’d just have to get VR goggles so as to not miss out. Something like what World of Warcraft did for MMO gaming, say. But the VR gaming effort has been going on for something like a decade now, and nothing like that has really turned up.


  • Have a limited attack surface will reduce exposure.

    If, say, the only thing that you’re exposing is, oh, say, a Wireguard VPN, then unless there’s a misconfiguration or remotely-exploitable bug in Wireguard, then you’re fine regarding random people running exploit scanners.

    I’m not too worried about stuff like (vanilla) Apache, OpenSSH, Wireguard, stuff like that, the “big” stuff that have a lot of eyes on them. I’d be a lot more dubious about niche stuff that some guy just threw together.

    To put perspective on this, you gotta remember that most software that people run isn’t run in a sandbox. It can phone home. Games on Steam. If your Web browser has bugs, it’s got a lot of sites that might attack it. Plugins for that Web browser. Some guy’s open-source project. That’s a potential vector too. Sure, some random script kiddy running an exploit scanner is a potential risk, but my bet is that if you look at the actual number of compromises via that route, it’s probably rather lower than plain old malware.

    It’s good to be aware of what you’re doing when you expose the Internet to something, but also to keep perspective. A lot of people out there run services exposed to the Internet every day; they need to do so to make things work.

    Plus, I mean, unless you’re using a Threadiverse host as your home instance, how often are you typing its name?

    Having a hyphen is RFC-conformant:

    RFC 952:

    1. A "name" (Net, Host, Gateway, or Domain name) is a text string up
    to 24 characters drawn from the alphabet (A-Z), digits (0-9), minus
    sign (-), and period (.).  Note that periods are only allowed when
    they serve to delimit components of "domain style names". (See
    RFC-921, "Domain Name System Implementation Schedule", for
    background).  No blank or space characters are permitted as part of a
    name. No distinction is made between upper and lower case.  The first
    character must be an alpha character.  The last character must not be
    a minus sign or period.  A host which serves as a GATEWAY should have
    "-GATEWAY" or "-GW" as part of its name.  Hosts which do not serve as
    Internet gateways should not use "-GATEWAY" and "-GW" as part of
    their names. A host which is a TAC should have "-TAC" as the last
    part of its host name, if it is a DoD host.  Single character names
    or nicknames are not allowed.
    

    RFC 1123:

       The syntax of a legal Internet host name was specified in RFC-952
       [DNS:4].  One aspect of host name syntax is hereby changed: the
       restriction on the first character is relaxed to allow either a
       letter or a digit.  Host software MUST support this more liberal
       syntax.
    
       Host software MUST handle host names of up to 63 characters and
       SHOULD handle host names of up to 255 characters.
    










  • You mean just the brand, or the manufacturing?

    I mean, branding something is trivial.

    But if you want to manufacture it in Europe, then you have to compete against companies who are going to be manufacturing in China, and manufacturing wages are going to be lower in China, so it’s going to be at a price disadvantage.

    I was just commenting yesterday where some guy wanted to buy a keyboard out of the EU or Canada instead of a Unicomp keyboard because he was pissed at the US. He was asking about buying a Cherry keyboard. Cherry just shut down their production in Germany after cheaper Chinese competition clobbered 'em.

    If you want to have stuff manufactured in Europe, you’ve got kinda limited options.

    1. Get some kind of patriotic “buy European” thing going, where people are intrinsically willing to pay a premium for things made in Europe.

    2. Ban imports. My guess is that in general, Europe will not do this unless they have some negative externality, like national security, associated with the import (think, say, Russian natural gas), since it’s economically-inefficient.

    3. Leverage some kind of other comparative advantage. Like, okay. Maybe one can’t have competitive unskilled assembly line workers. But maybe if there’s really amazing, world-leading industrial automation, so that there’s virtually no human labor marginal cost involved, and one scales production way up, it’s possible to eliminate enough of the assembly line labor costs to be competitive.


  • I’ve never used the software package in question.

    If you already own the software, and if the hardware it uses to talk to the microcontroller is on a serial port or USB-attached serial port, then you can most-likely just run it under WINE. This isn’t a VM, but a Windows compatibility layer — you don’t need to run a copy of Windows in a VM and all that. It’d be my first shot. That way, you can just use it like any other Linux program, don’t need to blow extra memory or overhead on running Windows in a VM.

    So, say the program in question has an installer, picbasic-installer.exe.

    So you’re going to want to install WINE. I don’t use Arch, so I’ll leave that up to you, but I believe that the Arch package manager is pacman. They may have some graphical frontend that you prefer to use.

    Then go ahead and, in a virtual terminal program, invoke picbasic-installer.exe — assuming that that’s what the installer is called — under WINE:

    $ wine picbasic-installer.exe
    

    That’ll run the installer.

    Now, my guess is that that much won’t have problems. And that WINE will run the thing. And it’ll probably let you compile BASIC programs.

    You can go ahead and fire up your PICBASIC PRO program. I don’t know how you launch Windows programs in your Arch environment. In general, WINE installers will drop a .desktop file under ~/.local/share/applications, and that can be started the way any other application can. I use a launcher program, tofi, to start programs like that under sway using tofi-drun, but you probably have a completely different environment set up. My guess is that your desktop environment on Arch probably has some kind of system menu of applications or something like that that will include WINE programs with a desktop file in it. Or maybe you have some program that shows a searchable list of programs and can launch from that. KDE Plasma, GNOME, Cinnamon, etc will probably all have their own routes, but I don’t use those, so I can’t tell you what they do. I’ll leave that up to you.

    What you’re likely to run into problems with is that if the PICBASIC PRO program wants to talk to that microcontroller programmer via a serial port (which on Windows would probably be COM0 or COM1 or whatever), it’s going to need to talk to /dev/ttyS0 or /dev/ttyS1 or whatever on Linux, or if it’s a USB-attached, /dev/ttyUSB0, /dev/ttyUSB1, etc. Ordinary users probably don’t have permission to write directly to them, by default.

    There are a couple ways to grant permission, but one of the most-straightforward ways is to add your user to a group that has permission.

    The basic Unix file permission system has each file — including device files, like /dev/ttyS0 — owned by one user and one group.

    On my Debian trixie system:

    $ ls -l /dev/ttyS0
    crw-rw---- 1 root dialout 4, 64 Jan 15 20:46 /dev/ttyS0
    $
    

    So that serial port device file is owned by the user root, which has read and write privileges (the first “rw”) and the group dialout, which has read and write privileges (the second “rw”). Any user that belongs to that group will be able to write to the serial ports.

    On my system, my user doesn’t belong to the “dialout” group:

    $  groups
    tal cdrom floppy sudo audio dip video plugdev users render netdev bluetooth lpadmin scanner docker libvirt ollama systemd-journal
    $
    

    So I’m going to want to add my user to that group:

    $ sudo usermod -aG dialout tal
    $
    

    Group permissions get assigned to processes when you log in (that is, usermod just sets what groups the process started when you log in as has, and then all its child processes). Technically, you don’t have to log out to do this — you could run sg dialout at this point, and then from that shell, run wine and see if it works — but I’d probably log out and then back in again, to keep things simplest. After you do that, you should see that you’re in the “dialout” group:

    $ groups
    night_petal <list of groups> dialout
    $
    

    After that, you should be able to use the program and write code to the microcontroller.



  • Unless you have some really serious hardware, 24 billion parameters is probably the maximum that would be practical for self-hosting on a reasonable hobbyist set-up.

    Eh…I don’t know if you’d call it “really serious hardware”, but when I picked up my 128GB Framework Desktop, it was $2k (without storage), and that box is often described as being aimed at the hobbyist AI market. That’s pricier than most video cards, but an AMD Radeon RX 7900 XTX GPU was north of $1k, an NVidia RTX 4090 was about $2k, and it looks like the NVidia RTX 5090 is presently something over $3k (and rising) on EBay, well over MSRP. None of those GPUs are dedicated hardware aimed at doing AI compute, just high-end cards aimed at playing games that people have used to do AI stuff on.

    I think that the largest LLM I’ve run on the Framework Desktop was a 106 billion parameter GLM model at Q4_K_M quantization. It was certainly usable, and I wasn’t trying to squeeze as large a model as possible on the thing. I’m sure that one could run substantially-larger models.

    EDIT: Also, some of the newer LLMs are MoE-based, and for those, it’s not necessarily unreasonable to offload expert layers to main memory. If a particular expert isn’t being used, it doesn’t need to live in VRAM. That relaxes some of the hardware requirements, from needing a ton of VRAM to just needing a fair bit of VRAM plus a ton of main memory.


  • Are Motorola ok?

    Depends on what you value in a phone. Like, I like a vanilla OS, a lot of memory, large battery, and a SIM slot. I don’t care much about the camera quality and don’t care at all about size and weight (in fact, if someone made a tablet-sized phone, I’d probably switch to that). That’s almost certainly not the mix that some other people want.

    There’s some phone comparison website I was using a while back that has a big database of phones and lets you compare and search based on specification.
