  • Yeah, but the flip side is that it also comes with controversy, and I could imagine that it’s more hassle for OpenAI than it’s worth.

    Plus, there are some scaling issues. There is a varying collection of social norms around the world that vary when it comes to sexuality. Some people are going to get really upset if there’s a chatbot that violates their social norms. Some of those social norms change (e.g. the UK just put out that restriction on choking pornography).

    And then you’ve got privacy issues. My own suspicion is that erotica might be a driver for LLMs-on-local-hardware.

    Given how much money OpenAI is burning, I’d guess that they really have to get agentic stuff, more-advanced stuff working. And I don’t know how much overlap there is on making general-knowledge AI and erotica generation stuff. Like, one point I recall someone making on /r/LocalLLama was that MoEs haven’t worked incredibly well with creative writing…but it might be that MoEs are a better approach for problem solving.

    Like, I agree that there’s demand. And I’m pretty sure that there’s gonna be an industry filling that (maybe after hardware prices have come down). But I’m not sure that it’s the best bet for OpenAI.






  • I’m not really understanding what it is you are concerned about.

    If it’s that the Javascript might be malicious, then a browser should be able to sandbox it. IIRC — and you probably want to confirm this, if you’re actively concerned — the Firefox security model is that if you open a file locally, it has local access, but if you open it from a webserver, it doesn’t. Like, Javascript running in your browser downloaded from a web server shouldn’t have local filesystem access.

    If you want to examine some code, but don’t want the code to phone home in some way, I’d remember that at least DNS is probably also a potential side channel. I’d maybe run the stuff in a VM without network access, if I were concerned about that.




  • Stephenson actually specifically addressed how people would feel uncomfortable around AR users from a privacy standpoint back in Snow Crash (as well as the fashion side).

    It’s a gargoyle, standing in the dimness next to a shanty. Just in case he’s not already conspicuous enough, he’s wearing a suit. Hiro starts walking toward him. Gargoyles represent the embarrassing side of the Central Intelligence Corporation. Instead of using laptops, they wear their computers on their bodies, broken up into separate modules that hang on the waist, on the back, on the headset. They serve as human surveillance devices, recording everything that happens around them. Nothing looks stupider, these getups are the modern-day equivalent of the slide-rule scabbard or the calculator pouch on the belt, marking the user as belonging to a class that is at once above and far below human society. They are a boon to Hiro because they embody the worst stereotype of the CIC stringer. They draw all of the attention. The payoff for this self-imposed ostracism is that you can be in the Metaverse all the time, and gather intelligence all the time.

    Gargoyles are no fun to talk to. They never finish a sentence. They are adrift in a laser-drawn world, scanning retinas in all directions, doing background checks on everyone within a thousand yards, seeing everything in visual light, infrared, millimeter. wave radar, and ultrasound all at once. You think they’re talking to you, but they’re actually poring over the credit record of some stranger on the other side of the room, or identifying the make and model of airplanes flying overhead. For all he knows, Lagos is standing there measuring the length of Hiro’s cock through his trousers while they pretend to make conversation.


  • So, the issue is basically that a lot of people — I think including Stephenson, given his portrayal of the Metaverse in Snow Crash — expected that the bar was getting viable VR headsets, and then getting over the hump of writing enough initial software, and then it’d just explode.

    The thing is that we have VR headsets that more-or-less work for playing VR games. We don’t have as many VR games as we do games designed around conventional hardware, but they’re out there. But…we haven’t really seen that explosion. People haven’t said “hey, I’ll drop maybe $300-$1k to have a larger FOV with more peripheral vision, some additional immersion, and the ability to use my head as an input.”

    Like, you’re saying “I can get a VR headset and play VR games in 2026”, which is true. But the state of the field is just nowhere near where advocates hoped it would be.


  • Maybe, but I’d lean towards disagreeing.

    Current HMDs have poor angular resolution, and are not drop-in replacement for existing monitors.

    I’d get an HMD once it hits something roughly comparable to today’s monitors in terms of angular resolution, and comfortable to use for as long. I probably won’t buy one just to play VR games. I don’t think that we will never get to the point that they’re a monitor replacement, though. It’s more-portable and can fill more of your visual field.

    And I think that at that point, it becomes a lot more appealing. You can have a private screen that people can’t see. You can potentially consume less power than a laptop screen, since you can have a dark environment where the light only needs to go to one place. Laptop form factor is kind of defined by the display; if you don’t have to do that, you can use other portable computer form factors. You can use the thing while walking.

    Once you have an HMD as a monitor replacement, then it’s a smaller bump to use it for VR purposes.

    Stephenson’s argument is mostly that either (a) it fails on the fashion front or (b) it’s creepy to have people just staring at random things. I think that fashion has been pretty flexible over the years, and that people already just talk at the air for cell phones with Bluetooth headsets.

    I think that if we never get mainstream VR HMDs, it’ll be because by the time we get there, we have some sort of direct-to-brain connection that just supersedes them. Not because we can’t make something that people will accept because of fashion concerns or because they’re worried about looking strange by looking in random directions using it.

    Many open source operating systems exist that can turn a computer with multiple NIC’s into a router

    Minor nitpick, but if you’re planning on sticking a NIC into a machine to make it a router, it’s probably more cost-effective to get a single NIC with multiple Ethernet ports than multiple NICs.



  • Now I just have to figure out whether I want to get another external soundcard for my gaming rig or if I can live with switching the USB cable back and forth between the two PCs or if I can get used to control the volume with software. I really like hardware knobs though

    I don’t know what you’re doing, but if your headphones are using a 1/4 inch jack or 1/8 inch jack and your devices have some form of audio output already, you can just use a plain ol’ analog mixer. That’ll give you knobs and let you hook multiple devices up.

    I keep my headphones plugged into one. I rarely actually use the other devices, but sometimes I’ll want to be listening to a radio scanner or a shortwave radio or some other things, and it lets me just pipe whatever into the headphones.

    searches Amazon

    https://www.amazon.com/LiNKFOR-Channel-Separate-Controls-6-35mm/dp/B0DDKBJFWY

    That’s $11 and looks like it’ll do 4 1/4 inch inputs. Looks like they also have RCA and 1/8 inch input versions (though those cost more, and there there might be more-inexpensive mixers).


  • Power supplies are largely fine as long as they’re not really old.

    Oh, I didn’t think about PSUs in my comment. Good thought.

    There was a period where a lot of bad capacitors went into PSUs and there was a rash of PSU and motherboard failures sometime around 2000. I remember some failed caps causing devices to die — I think I had a video card, a motherboard, and a PSU go. At the time, I thought that capacitors just must not last very long, didn’t find out about the fact that it was a specific issue with some capacitors until years later. But, yeah, today, that’d be pretty ancient, and I haven’t seen that for some time.

    searches

    https://en.wikipedia.org/wiki/Capacitor_plague

    The capacitor plague was a problem related to a higher-than-expected failure rate of non-solid aluminium electrolytic capacitors between 1999 and 2007, especially those from some Taiwanese manufacturers,[1][2] due to faulty electrolyte composition that caused corrosion accompanied by gas generation; this often resulted in rupturing of the case of the capacitor from the build-up of pressure.

    High failure rates occurred in many well-known brands of electronics, and were particularly evident in motherboards, video cards, and power supplies of personal computers.

    A 2003 article in The Independent claimed that the cause of the faulty capacitors was due to a mis-copied formula. In 2001, a scientist working in the Rubycon Corporation in Japan stole a mis-copied formula for capacitors’ electrolytes. He then took the faulty formula to the Luminous Town Electric company in China, where he had previously been employed. In the same year, the scientist’s staff left China, stealing again the mis-copied formula and moving to Taiwan, where they created their own company, producing capacitors and propagating even more of this faulty formula of capacitor electrolytes.[3]

    I do think that one issue with PSUs is that power demands of high-end CPUs and GPUs have also increased. If the PSU is rated for your system, then no problem, but I’d want to make sure.

    Also, PSUs have fans, and while I don’t think I’ve ever had a PSU fan go, thinking back…fans do have moving parts and are IME one of the more-prone-to-see-failures components. I have definitely had CPU fans and case fans die — start making noise and ultimately seize up, as the bearings wear out.

    Cases basically can’t fail unless you destroy it on purpose.

    True, though I’ve also had cases come with a lot of parts, especially if you have toolless mounting or something. That’s one where I personally have always thrown out my old ATX cases, though it’s not as if they’re nonfunctional or anything. I even have the leftover parts, but they’re in some box somewhere.

    But I’ll concede that that’s probably just me. I mean, if someone wanted to, they could probably do fine with an old case.

    Air coolers don’t go bad.

    The aluminum/copper/etc heatsink itself will last forever, but for about the past 30 years, most will have had a fan on them. Now, granted, it’s also almost certainly replaceable, and it’s not hard to get new fans, but the fan can die.

    Liquid coolers will eventually need maintenance, but as long as they’re not really old should be fine.

    Huh. Well, that sounds good. I’ve been curious to see how these do. I’m on the first system I’ve used with an AIO liquid cooler. So far, it’s been remarkably quiet, had a lot of cooling capacity, and not had a huge amount of mass hanging off the motherboard — I’m glad that I got it, even if it cost more — I but I have wondered about pump longevity.

    Used liquid coolers might be interesting, as long as one can get the appropriate mounting bits, haven’t been thrown out. I remember that mine came with a bunch of brackets and such for various sockets. Do need to deal with cleaning off old thermal paste, though.


  • I’m looking at a Trixie system right now, and /dev/input/js0 appears just as expected. Is it possible that you modified your Debian installation way back then, to disable your js devices? Maybe you (or some package you installed) applied a udev rule to block them?

    Nope. Vanilla /etc/udev (well, okay, there are some unrelated changes for snapd and one to keep an JBOD enclosure form spinnign down drives). The joydev module isn’t even loaded.


  • A great many games rely on a library for joystick input.

    Sure, but that doesn’t mean that they’re using the js API at the kernel level.

    SDL, for example, which will use js devices depending on the circumstance.

    Your own link points out that even SDL 1 — very old now — doesn’t use the js interface unless forced to do so.

    I’m running Debian trixie. IIRC in the past, for a while when the evdev interface showed up, a problem was that games that could talk to both interfaces would sometimes get double input, because a number would aggregate all input from all joysticks, and so if one had both the js and evdev interfaces visible, they’d see it as two joysticks both; a fix was to not expose them via the js API, rather than leaving them exposed via both. I don’t know how that’s evolved over time, but it may have been a factor encouraging not exposing them by default. I’ve certainly seen the “double input” behavior myself, maybe ten, fifteen years back.
