numpad0··on Singapore govt dating app uses Gale-Shapley stable marriage algorithm
Population density and infant mortality had changed a lot too in the last 100 years. Income disparities, working hours, and climate too in the last 50.

...is this exterior design AI generated?
numpad0··on NASA asked several former SR-71A staffers to help secret restart
Yeah, China can probably do that too in a WW3 situation. A nuclear PSU wherever low enough latitude with a telescope next to it shooting up anything moving it sees. LEO satellites can't avoid covering everywhere on Earth where latitude is lower than its inclination. It probably has to be articulating and tracking, not like fixed Minecraft beacons, but even that will do its job eventually.

More like, you can just launch couple rings of sand into the polar orbit of Starlink altitude ranges. It'll wipe them all off like a window wiper over few days or so. Or the killer sat could have thrusters to rendezvous with each one, but it'll be more complicated with the size of Starlink constellation.

Satellites are defenseless and easily shot down, either one by one using ballistic missiles or by creating a sweeping ring of debris, in a full scale WW3 where things like treaties and sanctions don't matter
numpad0··on Nissan's third generation e-POWER powertrain
I don't know, but people do buy cars so long their financial and parking situations allow. Many seem to be used for non-daily/non-daytime purposes(Home Depot/IKEA/Costco, kids/pets/luggage too loud/bulky/stinky for trains, had a bad day and must hit touge at 2AM, whatever). ICEs probably fit those use cases better than commuter EVs as they are, which are built around constant trickle charges and regular driving.
numpad0··on Nissan's third generation e-POWER powertrain
Yeah, they do exist but IIUC, real world deployments are rare. I totally forgot about this when writing the original comment, but a lot of these systems can't take many SUVs and all Tesla vehicles(including Model 3) mainly due to width and also to height. Maybe that is a compounding factor for rarity of those upgrades.
numpad0··on Hijacking the PS5's RTMP stream
2-3fps is weird. They should all do (lossy compressed) 1080p30 over USB 2.0.

The lowest end of HDMI captures used to use HDMI-PAL converter wired to an S-Video capture chip onboard. That was completely superseded by MacroSilicon MS21xx chips that actually capture HDMI. The ones that are now everywhere are based on those MacroSilicon chips.

numpad0··on Does Reddit have an astroturfing problem? What the data suggests
old reddit is only accessible by blocking access to www. Account pages are also dynamically hidden and it can be difficult to do that.

The trays that hold cars are either passed between different rails or rotated around like a paternoster lift(the Prague city hall weird elevator thing). It's just incompatible with the concept of a cable, and a third rail or giant bus bar docking plug upgrades for those systems would be too costly and risky.

Maybe that might have happened already if Japan was as insane as it was in 1995, but it just costs too much right now.

I think massive CHAdeMO plugs might have been for ultra rapid charging that never rolled out. There are brochures of 350kW+ watercooled CHAdeMO charging test equipment floating online, noted as plug limited to 200kW, dated at least as far back as 2015. That was when Tesla was still rolling out V2 150kW. So the plug overall dimensions and pin sizes are probably way overspecced for what it is in practice.
numpad0··on Parley: Federated, decentralised chat that speaks plain IRC
This is the path forward for the Internet. Social media of near future will have to be fully decentralized.

The levels of financial censorship had reached the point where third party contents hosted by any centralized entity, be it a publicly traded company like Twitter or just a volunteer individual like on a Mastodon instance, is basically unviable. In the latest case with Clip Studio asset store incident that happened just last week, completely benign materials such as simple drawing reference materials of abstract men playing soccer/football and kimono brush patterns for a snake were flagged and deleted as "pornographic or violent". There is nothing SFW at this point; the thresholds for censorship just keeps going up and it maintains constant pressure against all expressions however innocent - if everyone follows their rules, their rules must change to make up violators. Rules and standards also significantly diverge between places and photos of people can be literally illegal by standards of somewhere or someone deeply disconnected, at this time.

While the absurdity of that is fought in the field of politics or whatever ways that works, social media has to switch to distributed online/offline mesh networks that can still create the viral behaviors, one which nobody is forced to host or share what they personally consider illegal or risky, unlike raw P2P system that could be labeled as itself illegal and/or its use inherently malicious, as how Winny and later Bittorrent, to some extent, was made out to be. It has to be something like a distributed hybrid of Google+, Discord, IRC and Reddit, but with minimum centralized infrastructure that can be plausibly operated as not primarily intended for blatantly illegal use cases that would justify helicopter raids and flashbangs into living rooms(which European counter terrorism units have done in the past; they've been that much deranged for years).

IMO the challenge is in making it trivially selfhostable. At least the server part has to be usable by someone who could barely install a GPU, and ideally the phone app should work as a server for local friends for completely legitimate fun purposes. Then it also has to be able to handle what comes down or goes up to the global net at the same time. How it could be done behind heavily NAT'd current Internet can be tricky.

numpad0··on Nissan's third generation e-POWER powertrain
Yeah, so few households that still own a car but don't use for commute choose cheaper ICEs that require no attention during weekdays. Then company cars driven weekdays when necessary remain ICE for familiarity as well as various EV chicken and egg problems.

> bumfuck nowhere with expensive electricity, zero solar power and a daily 5 hour commute

If we put aside 5 hour commute, this describes central Tokyo, not bumfuck nowhere. Bumfuck nowhere has land for offgrid solar and therefore free home charging.

If the city you're in offers free roadside parking with L1 or L2 charging on light poles, good for you, but Tokyo and Japan at large isn't like that at all(unattended roadside parking is banned nationwide and robotic garages are everywhere).

European Model S has Type 2 in that location, only ones that don't fit is the Type 2 CCS with giant DCFC pins below the regular Type 2. NACS is just Tesla doing Apple.
numpad0··on Nissan's third generation e-POWER powertrain
It's because street parking is banned nationwide and none of big cities in Japan are interested in EVs. There are close to zero will to make EVs viable in Japanese cities, and people aren't buying unviable products, and Japanese automakers which primarily make products for Japanese middle class which somehow magically sell like hotcakes globally therefore aren't making many EVs.

Nissan is a bit of an outlier in that they are a bit more charitable and more invested in electrification, but they can't ignore the Japanese consumer demand that cars need to be able to run on gas. So they do exactly that, and make an EV with a gas engine that works with existing gas stations.

The point is that EVSE plugs are safer and European dryer plugs under the rain out in the open is technically kind of dangerous.
numpad0··on Nissan's third generation e-POWER powertrain
The entire metal platform that holds the car is moved around like a data tape in a tape library in mechanical systems. A third rail system to handle L1/L2 EV charging do exist, but upgrades aren't common. I think not many are being newly built but there are many operating in ultra dense areas.
numpad0··on Nissan's third generation e-POWER powertrain
Machine guns are just paperweights if arrows are dime a dozen but 6.8x51mm is still at advanced stages of development. EV charging in mechanical parking system is still an unsolved problem and gas filling experience remains more than tolerable.
numpad0··on Nissan's third generation e-POWER powertrain
IIRC both Nissan and Toyota have a dual motor options with super weak rear motors, largely to cover "but snows" arguments. The entire car largely remains to be boring family FWD cars, not like beefy Tesla duals. Maybe GP is referring to those.
numpad0··on Nissan's third generation e-POWER powertrain
I forgot which marketing name it was, but one of Honda 1-motor systems that used the motor in clutch pack had a major design oversight that it can't handle a traffic jam in an incline, which happens in (of all places)Japan; the HV battery runs out and the car needs to be towed and/or driven at higher speed to both cool down and fill back up. Generator plus traction 2-motor systems feel stupid but it's necessary to cover those situations.
numpad0··on Nissan's third generation e-POWER powertrain
TFA is exactly that...

I think it's also because EREVs need a performant generator that isn't much different from the drive motor. So you'll have a full ICE+EV drivetrain on top of an EV as its battery for it to work, which is not ideal.

Compared to that, other hybrid systems like the motor-clutch combo packs that sit between the ICE and gearbox, as well as the fixed gear Toyota systems, can have motors that are weaker, lighter, and cheaper than the ICE, while being able to be additive to the ICE power output. That makes more efficient use of steel and copper than full serial setups.

BMW i3 had such EREV option, but it apparently used a cheap OEM bike engine(not like a BMW Motorrad engine) and also could not overcome power draw of the EV drive motor. So it literally just extended the range, not allowing it to run indefinitely at highway speeds with just refueling. Nissan e-POWER system is powerful enough to do that, but then the readers of comment will have to back to the line 3.

numpad0··on Owed a billion dollars in Nvidia stock
If he's arguing that he could effectively revoke his past final decision to sell it all at not-billions by demanding withdrawal of hypothetical now-billions from NVIDIA, I wouldn't be sure what system will happily grant him that...
numpad0··on When did Google get so weird?
This whole tree just made me realize that people have wildly different prompting styles, and Gemini is probably too specialized for usage patterns of long-time Google Search users. The prompt my finger generated(before this comment was posted) was "are there any terminal emulator that supports gesture actions, on macOS, other than iterm2", and Gemini gave me Tabby, WezTerm, Kitty, and BetterTouchTool gestures.

This is a different experience to GP from query to result. I thought they've all fixed that issue of difference in tones affecting results. I guess it was never easily fixed.

numpad0··on Unsealed Briefs in Authors’ Case v. Microsoft/OpenAI
It's not. You be performatively hostile and people be hostile to you. That's all.

Car brands don't pitch cars as horse replacements. They put names and icons of horses on cars and horse riders love them. No one is complaining that horses had replaced cars.

AI startups pitched AI like it's a coagulation of malice and hostility against humanity on tap. People aren't liking it. Of course they won't. No intelligence would, natural or artificial. It's wild that they don't get that.

numpad0··on Generate fonts where every LLM token is the same width
I think the demo font might not have Chinese characters at all. Most Latin fonts don't include CJK, and the system will fill in missing characters with available Chinese fonts. CJK fonts OTOH do include Latin characters.

As for tokenizers - I reckon that most of them are not optimized for CJK; they're good enough, and AI performance in CJK languages, so far, haven't been the top priority matter.

numpad0··on The Rise of Audio AR
I was bracing a bit before clicking the link thinking about chances that this is about KU100 and 3Dio Free Space selling to consumers, not exactly like hotcakes but like nicer winter overcoats or more premium lawnmowers. OK, we're not there yet.
numpad0··on ASML says it sold 'absolutely nothing' in Europe in 2026
It can be complicated to draw a line between cultural elements worth preserving and crazy religious fantasy that needs to go. Indian caste system, IIUC, is deeply intertwined with their identity and ethics that it cannot be just cut out and removed. It is also partly coming from practical needs just like food related taboos of Middle Eastern religions that would need to be explained for its removal to be justified following the Chesterton's Fence principle.

---

absolute OT trivia that I needed a place to drop: the Indian karma system do not consider beings outside of animal kingdom, e.g. a roadside tree, to be alive and directly involved in the karma and reincarnation and all that, and apparently so did not the original Indian Buddhism. It was originally Chinese, and more prominently Japanese, exposition and localization of Buddhism that changed it up to be the current Studio Ghibli form of it that yes mountains and rivers and 100 year old Italian combat biplanes can all be alive and sentient and that you just ate a carrot is a sort of your original sin and even strictest of vegetarianism is not guilt-free. Your LLM can elaborate on this if necessary...

numpad0··on Toyota is taking the Corolla electric
IMO: every countries and localities have the concept of "but where are you FROM", to varying degrees. People just don't expect Japan to be a big enough place that could have such a thing, thinking it's like a tiny dying village at the end of a small branch near the tail end of road to Rome, distracted by its Westernized facades and microscopic presence in the world. It doesn't register as a nation with population size of France and Germany combined. So there's often a bit of divergence between perception and reality coming from there.
numpad0··on Oracle on the hook to pay data centre investors even if site has no electricity
Most fuel cells can't be recharged. They take combustible gases, re-assemble the molecules in the gas into H2O or something chemically stable, and release the energy delta as voltage potentials. The cells work purely as catalysts. Only the fuels are expended.

It's just a type of battery, that takes fuel, as its refillable energy source. Weird but it works.
