@lanodan@queer.hacktivis.me @TindrasGrove@infosec.exchange as I understand, it's quite a common thing for unhoused people to go through this cycle:

  • get shitty prepaid phone
  • sign up for accounts with SMS 2FA
  • be required to use those accounts to access benefits
  • get caught in an encampment sweep, and all their shit including their phone gets thrown away
  • oops, they can't access their 2FA any more
  • ...get shitty prepaid phone and create all new accounts

@pseyfert @uint8_t honestly, in so much of the US, roundabouts are so new that the vast majority of drivers have never actually been trained on how to use them, so we figure out how to use them based on context clues and signage at the roundabout when we arrive at the roundabout. IIRC my state's handbook for drivers 20 years ago didn't even mention roundabouts. (the current version does, and says to signal to exit.) I think the only time I've seen anyone other than myself do it is when the first exit is being taken (so at that point it just looks like a normal right turn). and I've never actually heard of "signal to tell a driver that you want them to let you into their lane when the light goes green" as a thing in the US. I'd even think of rolling down my window and verbally asking to be let in, before I'd think of that.

@benoit @TechConnectify oh! and in my experience, the limitations on regenerative braking on Toyotas are not because of MG2 being smaller than, say, e-Power’s traction motor. it’s three factors: the battery, how conservative Toyota’s ABS tuning is, and cooling. basically, it’s not possible to get more than about 27 kW of regenerative braking on a Gen 4 Prius unless it’s the PHV/Prime, because that’s what the battery maxes out at. (there’s definitely been times I wish my Gen 4 was a Prime, not just because a PHEV would work great for my commute, but because the bigger battery can take more power and energy in regen.) given that MG2 is rated for 53 kW… yeah, MG2 is not the limiting factor here. Toyota’s general approach to ABS on hybrids is, if there’s any disturbance under braking, cut off almost all regen until the brake pedal is released. open differential means the easiest wheel to lock will get locked by regen, so I get why they have to be careful, but you could use approaches like those used for friction brake ABS and pulse the regen to determine the traction limit instead… but Toyota doesn’t. and, on non-PHEV Toyotas, the planet carrier spins the oil pump for the transmission, so under extended regenerative braking, they’ll spin up the ICE just to cool down the transmission. all three of these problems could be solved without changing the fundamental behavior of a power-split hybrid system (and two of them actually are solved by the PHEVs).

@TechConnectify so, on the serial implementations. purely serial hybrids have another Achilles heel than just conversion losses: the size (and weight, and cost) of the MGUs. note that the Toyota MG1 and MG2 are pretty small - the fact that a significant percentage of ICE torque goes through a mechanical path, bypassing the serial path, means that MG2 needs to only be sized to take battery+MG1 power, not battery+full ICE power as a serial hybrid would need. Nissan’s e-Power system, which is purely a serial hybrid, isn’t terribly inefficient at low speeds as I understand - a bit worse than the Toyota system in comparable models, but not much - but falls completely on its face at non-Japanese (that is to say, faster than 100 km/h) highway speeds. the real reason why Nissan made it was they had Gen 1 LEAF motors lying around, and they could reuse them in a serial hybrid system. your Gen 1 Volt wasn’t purely a serial hybrid, and it had a few different modes it could operate in, one of which was a single-speed parallel hybrid mode, specifically to avoid the conversion losses of serial hybrid operation when on the highway. (the other notable improvement over a pure serial hybrid was that it could disconnect MGA from the ICE and connect it to the wheels, when high electric power was requested, so that MGB could be somewhat smaller/lighter/cheaper.) as I understand, the big efficiency problem the Gen 1 Volt had wasn’t really the hybrid system, it was that the engine tuning was not complete and they didn’t get a chance to optimize efficiency, only to get it to comply with emissions (and that they run super high EGTs to keep the catalytic converter hot, and then just keep running at those super high EGTs all the time). that said, a better comparison may be to Honda i-MMD - similar engine efficiency to Toyota’s best, and a similar serial-hybrid with a single-speed parallel hybrid mode. this does… pretty well, despite not having the Gen 1 Volt optimization of an undersized traction motor and repurposing the generator as a second traction motor in EV mode. …and then there’s the Chinese automakers. as far as I can tell, most of the Chinese systems are essentially developments of the Honda i-MMD or Mitsubishi Outlander PHEV (same idea as i-MMD) concept, with the addition of a 2-4-speed gearbox (possibly a DCT) to allow the ICE to connect to the axle at multiple gear ratios. BYD’s system is, I believe, “what if we just did the Gen 1 Volt system but better?” these seem to be doing shockingly well, but I’m sure some of this is BYD and Geely breaking 46% peak thermal efficiency, when the best Toyota can do is 41%.

@aoanla @oddtail there's a few reasons I can think of for everything (even, on some laptops, RAM and storage) being soldered down on laptops, FWIW: soldered connections are lower resistance and impedance/capacitance than socket connections. this means higher speeds for lower power consumption. (this is actually why CAMM is replacing SODIMMs in some high-end laptops - it gets you similar speeds to soldered RAM, but a user-serviceable package, by using similar technology to LGA CPUs.) sockets are themselves points of failure, especially when a device is jostled. sockets add thickness and weight. when laptops all used 18650 cells, and the laptop was a minimum of ~20 mm thick not including the screen, that wasn't a problem, but now it is more of a problem. ...and the lack of upgradeability *does* have benefits for the manufacturer, unfortunately.

@mrundkvist one interesting thing is that labor cost is a major factor in how much it costs to travel over a long distance, which is part of why higher speeds can be cheaper even if the energy costs are much higher (this is why the highest-speed rail services are so important to displace air travel)

@elricofmelnibone @tommorris so I can see why they want these verification laws, from two directions, and why it’d be seen as different from power tool warning labels. (to be crystal clear: I vehemently oppose age verification laws.) for your power tool example… if you use a chainsaw irresponsibly, the danger is to yourself and people within a tree’s height radius of the chainsaw (and, if someone’s running a chainsaw, a “reasonable person” is going to stay well clear without PPE). if you use, say, a car irresponsibly, you could easily hurt dozens of people who can’t easily avoid the car, so drivers are required to be licensed. so, you could make the argument that using a computer irresponsibly could hurt billions of people. (this is an incredibly weak argument, though, and it isn’t even what these people are actually arguing (although the speech case of this may be what they want). there’s basically two ways you can negligently harm someone with a computer: speech, or spreading malware. the speech case, in the US at least, requiring someone to get licensed to be able to speak to a large audience at all (outside of when it takes up a limited shared resource like street space or RF spectrum) would be seen as beyond the pale if it didn’t involve computers. the malware case… the equivalent laws would be ones allowing partial civil liability for being negligent in securing a car (leaving it unlocked with keys in the ignition, for instance) and a thief subsequently committing crimes with it, or allowing civil and criminal liability for a thief using an unsecured firearm to commit crimes. in both cases, they’re an after-the-fact thing, licensing isn’t used to prevent those (except in two US states where licensing is required to own any firearm).) the other direction that I think is closer to what they’re claiming to want: meatspace businesses that sell “vices” (think alcohol, tobacco, sexual products/services, and things that could be abused as drugs), are regulated and are required to age-verify their customers, and in some cases are required to ban underage people from the premises entirely. however, the equivalent policy to that is requiring age verification to enter a porn site, not age verification to use a computer altogether. (and, of course, age verification at meatspace businesses often involves someone looking at you, looking at your physical ID, and handing it back, where age verification online has almost always involved some kind of surveillance capitalism practices with the information being stored, so even then it isn’t equivalent.) I don’t even know what the equivalent to age verification to use a computer at all would be, age verification to be allowed to go outside?!? (yes I know curfews are a thing, but those are time-limited)

@TechConnectify on patents: for GM specifically, I don’t think this was an issue at all. GM was making two-mode power-split transmissions as early as 2003 (the Allison EP40/EP50, now known as the H40EP and H50EP), and selling consumer vehicles with them in 2008 (the 2ML70 used in the GMT hybrids, as well as the BMW, Chrysler, and Mercedes vehicles using that powertrain). and, the Gen 2 Volt basically used a scaled down version of the Allison EP system. for other automakers, maybe? but, yeah the patents are dead now. and, finally, for locomotives… as I understand the problem there isn’t torque output per se - gearing turns horsepower into torque - but rather making the kind of gearbox that has wide enough range to get a 2 mile long consist moving from a stop uphill, as well as to go 80 MPH, while surviving behind a 3-4000 hp diesel. diesel-hydraulic systems using torque converter automatics are a thing in DMUs that have multiple smaller engines, but not so much in locomotives. (also, with longitudinal engines, you’d have to turn the power 90 degrees and eat some losses there. and, with a diesel-electric, you get dynamic braking for free as an additional way to slow the locomotive down.)

@oddtail usually "bricked" means "it doesn't boot, and the normal recovery methods don't work" - as in, it now has as much utility as an actual brick (actually less, because you wouldn't use it as part of a building's structure or facade, or as a paving material) "unbricking" is *sometimes* possible, using methods outside of the usual recovery bootup, but it used to mean that no recovery was possible either
