  • 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.









  • 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.

  • That’s why they have the “Copilot PC” hardware requirement, because they’re using an NPU on the local machine.

    searches

    https://learn.microsoft.com/en-us/windows/ai/npu-devices/

    Copilot+ PCs are a new class of Windows 11 hardware powered by a high-performance Neural Processing Unit (NPU) — a specialized computer chip for AI-intensive processes like real-time translations and image generation—that can perform more than 40 trillion operations per second (TOPS).

    It’s not…terribly beefy. Like, I have a Framework Desktop with an APU and 128GB of memory that schlorps down 120W or something, substantially outdoes what you’re going to do on a laptop. And that in turn is weaker computationally than something like the big Nvidia hardware going into datacenters.

    But it is doing local computation.



  • I’m kind of more-sympathetic to Microsoft than to some of the other companies involved.

    Microsoft is trying to leverage the Windows platform that they control to do local LLM use. I’m not at all sure that there’s actually enough memory out there to do that, or that it’s cost-effective to put a ton of memory and compute capacity in everyone’s home rather than time-sharing hardware in datacenters. Nor am I sold that laptops — which many “Copilot PCs” are — are a fantastic place to be doing a lot of heavyweight parallel compute.

    But…from a privacy standpoint, I kind of would like local LLMs to be at least available, even if they aren’t as affordable as cloud-based stuff. And at least Microsoft is at least supporting that route. A lot of companies are going to be oriented towards just doing AI stuff in the cloud.


  • You only need one piece of (timeless) advice regarding what to look for, really: if it looks too good to be true, it almost certainly is. Caveat emptor.

    I mean…normally, yes, but because the situation has been changing so radically in such a short period of time, it probably is possible to get some bonkers deals in various niches, because the market hasn’t stabilized yet.

    Like, a month and a half back, in early December, when prices had only been going up like crazy for a little while, I was posting some tiny retailers that still had RAM in stock at pre-price-increase rates that I could find on Google Shopping. IIRC the University of Virginia bookstore was one, as they didn’t check that purchasers were actually students. I warned that they’d probably be cleaned out as soon as scalpers got to them, and that if someone wanted memory, they should probably get it ASAP. Some days prior to that, there was a small PC parts store in Hawaii that had some (though that was out of stock by the next time I was looking and mentioned the bookstore).

    That’s not to disagree with the point that @[email protected] is making, that this was awfully sketchy as a source, or your point that scavenging components off even a non-scam piece of secondhand non-functional hardware is risky. But in times of rapid change, it’s not impossible to find deals. In fact, it’s various parties doing so that cause prices to stabilize — anyone selling memory for way below market price is going to have scalpers grab it.



  • I don’t think that memory manufacturers are in some plot to promote SaaS. It’s just that they can make a ton of money off the demand right now for AI buildout, and they’re trying to make as much money as they can in the limited window that they have. All kind of industries are going to be collateral damage for a while. Doesn’t require a more complicated explanation.

    Michael Crichton had some way of putting “it’s not about you” it in Sphere that I remember liking.

    searches

    “I’m afraid that’s true,” Norman said. “The sphere was built to test whatever intelligent life might pick it up, and we simply failed that test.”

    “Is that what you think the sphere was made for?” Harry said. “I don’t.”

    “Then what?” Norman said.

    “Well,” Harry said, “look at it this way: Suppose you were an intelligent bacterium floating in space, and you came upon one of our communication satellites, in orbit around the Earth. You would think, What a strange, alien object this is, let’s explore it. Suppose you opened it up and crawled inside. You would find it very interesting in there, with lots of huge things to puzzle over. But eventually you might climb into one of the fuel cells, and the hydrogen would kill you. And your last thought would be: This alien device was obviously made to test bacterial intelligence and to kill us if we make a false step.

    “Now, that would be correct from the standpoint of the dying bacterium. But that wouldn’t be correct at all from the standpoint of the beings who made the satellite. From our point of view, the communications satellite has nothing to do with intelligent bacteria. We don’t even know that there are intelligent bacteria out there. We’re just trying to communicate, and we’ve made what we consider a quite ordinary device to do it.”

    Like, two years back, there was a glut of memory in the market. Samsung was losing a lot of money. They weren’t losing money back then because they were trying to promote personal computer ownership any more than they’re trying to deter personal computer ownership in 2026. It’s just that demand can gyrate more-rapidly than production capacity can adjust.



  • I think that Cherry just sold off their German production facilities or something. I vaguely recall posting something along those lines when it came up in the news. Cheaper Chinese competitors kind of killed them off.

    End of Cherry production in Germany

    December 6, 2025

    Cherry, the internationally renowned peripherals manufacturer from Auerbach in the Upper Palatinate region of Germany, is ceasing its German production after 60 years. Cherry became particularly famous for its iconic keyboards, which are expected to continue being manufactured in the Far East. Production in Germany, however, is no longer profitable, according to management.

    Even though six decades of purely German production is a long time, Cherry is now, historically speaking, returning to its roots. These roots lay in the USA for the later German icon, as its Anglo-Saxon name suggests. Walter Cherry founded the company in 1953 in Highland Park, Illinois, and established the German production line in 1963. With the peripherals produced here, the company achieved a spectacular international breakthrough in 1983. That year, it launched the MX Switches, which have since defined the global standard for mechanical keyboards.

    However, a Cherry patent expired in 2014, protecting the company’s MX design. Since then, Chinese companies have flooded the market with equivalent but cheaper alternatives. Manufacturers like Kailh, Gateron, and Outemu now offer switches with innovative technologies such as the Hall effect, some of which even come pre-lubricated. The Hall effect is a magnetic actuation mechanism for variable actuation points. Far Eastern manufacturers have now mastered this technology better than Cherry.

    Completely relocating production to China will undoubtedly reduce costs and perhaps even bring Chinese expertise into the company. Industry leaders like Razer and Logitech took this path years ago.
