<p>Places like Japan are always treated very differently on social media from the rest of the world. The system doesn't work, the contents don't work, memes don't work. They won't do anything that shrinks an already postage stamp sized Japanese community on Reddit.</p>

<p>I know this isn't HN type of a topic or a comment, but looking at US from outside, the theme looks to be explicitly destroying US hegemony and meritocracy...<p>What I feel to be a common denominator for Trump, Thiel/Musk, and MAGA types, is that they are the people who "otherwise wouldn't have been chosen" for one reason or another. I've had stupidly engaged in a pointless argument with MAGA type people on some anonymous forum, and what I slowly realized is that a lot of them fail to hide having an okay picture of the actual reality when absolutely cornered and pushed hard, with the caveat that the chances for them getting any win whatsoever by embracing some alternative, conspiracy, false narratives is above zero, whereas the same for not doing so is at very most zero. There have been news reports of Bill Gates and Elon Musk both having engaged in quite some reprehensible acts on some island, but Gates would still always come first on headlines whenever they would be in a photo together. This would be contrast to how media universally reports Musk throwing the Nazi salute(which is the worst I've seen in any media that unironically makes me wonder how a real neo nazi would pause, exhale, say "you know," and shut up in German on camera reviewing it), which do yield a bunch of single name headlines. They would not have a chance of getting dopamine hit standing straight on both feet and looking straight ahead uttering all the correct words. Destroying everything that gets in the way to end this their "suffering" seem like the goal to me.<p>I mean, there's a very succinct and less nice word for that group of people that begins with the letter in the middle of the logo under the crown for the Dutch royal airline, but that word doesn't feel like it captures the verticality of this phenomenon.</p>

<p>Fission reactors are ran by pulling rods out just enough to keep the system at a state of equilibrium. If one of rods accidentally goes in, for any reason, the nuclear chain reaction therefore heat generation will slowly reduce. If there was also an automatic system that wasn't aware of that rod going in, it wouldn't be so weird that it will try to fight the fire suddenly dying down.</p>

<p>Probably because they use a bus that's harder to on-the-fly rewrite or because they sign commands.<p>comma openpilot do its thing by faking stock self driving unit talking to actuators over the in-vehicle network; a modern car is like a bunch of Pi on a LAN hosting microservices, but on a car specific network standard, usually the one called CAN bus, instead of the 802.3 we're familiar with. The manufacturer stock units is usually a camera unit integrated CPU sitting behind a hump behind the rearview mirror. comma devices tap into the cable going in there, sending out fake commands to other computers handling cruise control, brake, steering, blinker... etc.<p>This can break two ways: some communication standards like FlexRay are harder to tamper and fake, or some newer cars have tightened security clearly in response to comma doing its thing too well, many following the new EU cybersecurity standards which require commands to be signed and/or each of those Pi-like modules to be crypto paired against each others.<p>I think Stellantis car always had the first of those two issues of having something difficult that are not strictly anti-hacker hostile architecture. But could be both or I could be wrong altogether. The comma devteam seem to like 2015-2019ish hybrids from such brands as Honda, Subaru, Hyundai and Toyota for the presence of the remote control features in the actuator modules && lack of security getting in the way.</p>

<p>There are zero upfront no-questions-asked 3D printing services as well as such PCB/PCBA manufacturing services, but not a Buy Now style Mechanical Turk assembly line service, yet. So you'll have to do the non-scalable work and do the literal manu-facturing when it comes to tiny volume cottage industry products with no cash or volume to foot and amortize upfront costs. Which can be bypassed or minimized if it's supposed to be a kit and you only have to bag some parts. Also it blurs areas of responsibility in favor of the shop.</p>

<p>A lot of people who haven't seen one are confuse it with a trackball, but SpaceMouse and its kin aren't trackballs, they're double cascaded joysticks on a fixed mount shaped like a ball.<p>The stump om the base works as a 2 axis tilting joystick, and the stem of the ball works like its own 2 axis XY sliding pad with extra push/pull plus twist axes. There's a wire through the stem of the knob to get the readings. Together they capture the whole 6 axis deflections for the knob.<p>Trackballs OTOH is just rubbing a mousepad rolled up to be a ball to operate a Magic Mouse while charging.</p>

<p>Mouse sensors are usually ~16x16 CMOS cameras that just return signed int X/Y movements. Shutter speed is goverened by both luminosity and polling rates. There's no raw pixel output, and even in sensors that have it, it's for focus adjustment only and not useful in realtime sensing. They're also crazy cheap.<p>Therefore the cheapest way to do ball twist is to just put two sensors and use the error as the twist amount. You could use a singular high resolution highspeed camera pointed at the ball instead, but that won't be the cheapest way to do it.</p>

<p>Keyword recalling from a word in GP comment: photon downconversion is relatively easy and used widely, used in LEDs already, but upconversion require more exotic compounds and their efficiency is magnitude worse. Possible but not yet useful. It's certainly not like just using Lithium instead of Neon.</p>

<p>Unicode merges some Chinese and Japanese characters into same code points and leave others as they are, on random per-character basis. So Chinese guys gets a ton of Japanese mixed texts and it causes tons of problems.<p>Japanese users are angry when system chooses Chinese fonts over Japanese, Chinese users apparently suffer with a font mishmash of Chinese and Japanese all the time like a mid-word capitalization. The official sanctioned solution is to just commit a genocide and nuke the offending language out of the system or to attach IVS to every Japanese characters which is like zero padding every single characters by a byte or two.<p>It's really putting everyone in pain and making absolutely no one happy, which sounds like what a good compromise tends to be, but LLMs seem to be struggling with there being multiple completely separate language families sharing codepoints but not character shapes or syntax. I've seen a smaller LLM model use made up verbs spilling over from the other language. I believe ML guys don't like datasets that do that kind of things. Same apply to image models.</p>

<p>I don't know but last I glanced at it, the Unification was implied to be coming from Chinese pressure than Japanese. Each of Kanji/Hanzi countries already had each own acceptable common use character sets and those could have been just populated into each own spaces. That seemed like the original plan at some point.<p>There has to be a reason why it happened(as to why Unicode suddenly started insisting it has to fit inside a 2^16 total chars or whatever).</p>

<p>I would think that it would be the opposite. Nobody is seriously detoxing or comfortmaxxing AIs yet. Human brains are fed back its own output in learning mode, so we are great at removing whatever we feel uncomfortable from our output, online and offline. No such paths exist for AIs.</p>

<p>The usual Japanese talking point is that CSAM laws exist for rights and wellbeing of kids, which are real human being. If it's used/defined for cases that are not plausibly harmful to kids, such as some adults doing some things nowhere near kids using none of real materials, then it's often argued that the law is abusively defined/used, and/or plain broken. That talking point, incidentally, should logically validate against texts of laws, though sometimes it may not with the intents between the lines like you've brought up.<p>But that logic usually align perfectly with the texts of laws. Those laws aren't supposed to be adult pedos beating and correction laws. They're not pedo soft landing laws either, they are supposed to be parts of younglings protection laws, globally. Technically that should be all that matters. So there's that.</p>

<p>What makes that kinda complicated is that multi-user throughput of LLMs scale well but single-user performance often stays constant at low ends. If you could saturate e.g. 16 concurrent session-month of demand, you can just go buy 16 of 32GB GPUs and start charging monthly for inference. That could work if you had e.g. over thousand total employees with hundreds of devs eager to trying it out, but only if the company is also interested in a private inference experiment.</p>
