  • The crazy thing is, none of these articles seem to want to admit that AI is bad.

    As the old quote goes- “A time is coming when men will go mad, and when they see someone who is not mad, they will attack him saying, “You are mad, you are not like us.””

    In such an environment, nobody wants to admit they are not mad, lest they be attacked.

    Or as someone else said- I want a future where machines cook and clean and do menial work, so us humans can focus on art and poetry and writing. Instead we have a world where machines create art and poetry and books, so the humans can focus on cleaning and menial work. I don’t like this timeline.




  • I couldn’t agree more. Acting like a million dollar company is important.

    A million dollar company would recognize that reliable, continuous production and sales is more important to growth than the occasional hickup or a few extra bucks in the payroll budget. Thus, the million dollar company would hire sufficient staff that an occasional absence, even at a critical moment, would not harm production or sales.

    And a million dollar company would recognize that hiring sufficient staff is a wiser and more cost effective strategy than a possible labor lawsuit along with the associated bad PR.







  • Interesting idea. Seriously over-engineered though.

    If you want a ‘human washer’ you don’t need a $350k fancy chair with heart rate monitors. Just take a page out of the automatic car wash.

    Human stands in a stall. Shower allows human washing of hair and face. Then just hold arms out making a diamond in front of you (think TSA body scanner position, but with arms forward instead of upward) and a 360° robotic sprayer starts at the neck and goes down spraying soapy water, then back up again with a slight up angle to get the groin and armpits. Shower comes back on to de-shampoo hair, then the same 360 robot does two passes with clean water to rinse everything off.

    If you get fancy with machine vision and body position sensors, the 360 wand could flip 90° to do the hair and would be angled backward a bit so it doesn’t get water or soap in your face.

    You could build this for a lot less than $350k. And instead of $1500 worth of body sensors you have a $50 waterproof emergency stop button.


  • We used to be. The rules changed about 10 years ago.

    I’d rather have 120v wiring I can do myself than 240v wiring that I have to pay someone $hundreds just to replace a light switch.

    A lot of big appliances require higher power. Dishwashers, clothes dryers, fridges.

    Here in US dishwashers and fridges run on <1500w. A fridge should only use a few hundred watts tops unless it’s horribly inefficient. A dishwasher needs power for the heating element but ours do okay on 1500w, although yours probably heat up faster. We use a different plug for clothes dryers, usually a NEMA 10-30 or NEMA 14-30 (30A at 240v), sometimes NEMA 14-50 (50A at 240v) for really big stuff like EV chargers.
    Our power is split phase (two 120v legs, 180° out of phase, so either phase against neutral/ground is 120v, phase A against phase B is 240v). So with those plugs you either get both legs and ground or both legs plus neutral plus ground.

    Some powers tools, drill press, plainer

    Almost all US power tools run on 120v 15A.
    There’s a few really big ones, mostly designed for professional shops, that need some flavor of 240v, usually with a NEMA 6-15 outlet (like normal US outlet but pins are horizontal rather than vertical). These outlets are uncommon outside of wood shops.

    I never worry about load splitting,.

    The only time I’ve ever even considered this is a. charging my Tesla on 120v, or b. running a space heater and a hair dryer at the same time in the bathroom. :)

    Bottom line- yeah NZ system has higher power density but I don’t think the benefits outweigh the loss of ability to work on it yourself.


  • Okay but that’s more talking about the benefit of a 240v system. The question here was the benefit of the giant UK plug. Personally I would argue that 240v to every receptacle is not a major benefit, because very few devices require 3kw+. And in exchange you get a somewhat more hazardous system.
    I am curious if homeowners in NZ are allowed to work on their own wiring? Here in the US you are…


  • Your understanding is correct. It’s actually a very simple calculation: volts x amps = watts. Watts is the amount of total work done. So to use a water pipe analogy, imagine you have a pressure washer. Volts is the pressure in PSI. Amps in the flow rate in gallons per minute. Watts is how quickly it cleans your sidewalk. Thus, the 500 PSI pressure washer that can put out 2 gallons per minute does about the same amount of cleaning as the 1,000 PSI pressure washer that puts out one gallon per minute. However, as long as the hose can withstand the pressure, pushing out 2 gallons per minute requires a larger diameter hose.

    It’s the same way with wiring. The capacity of a wire is measured in amps. So if a device needs say 1200 watts, feeding it was 240v instead of 120v means you can use thinner wires everywhere. Including in the transformer that powers it.

    However, this type of gain only really makes a big difference when you get into very high power consumption devices. An electric kettle that takes 1500 w, in the US you are almost maxing out a single 15 amp outlet. In the UK the same kettle is using less than half of the outlets capacity. (Of course they just make a kettle that has twice as much output, because the Brits don’t want to wait for their tea). Amusingly, that 3 kilowatt tea kettle is one of the only places where you get a real perceptible advantage from a 240v system.


  • … How is that the case? You’re multiple loads end up with a cubic foot of plugs and receptacles. Like imagine I want to plug in a computer, two monitors, a printer, a desk lamp, a cell phone charger, and a laptop plug. None of these devices use more than 100 watts. In UK you need seven of those ridiculous giant plugs for all this. Even with a power strip it would be physically huge.

    In the US the power strip that would run all that stuff is barely a foot long.

    I have used power strips all my life and never once has one caught fire.


  • American here. I may be in the minority, but I think this plug design is absolutely stupid. I get that it has safety features, that you can put a fuse in the plug, that the outlets have switches, etc etc etc. But it is absolutely fucking huge. Ridiculously huge. And anywhere that you have multiple devices you want to plug in, it is totally impractical because it is so fucking huge.

    The fact is, very very few devices need 240v 13A. Yes I get that it is useful to have this ridiculous amount of power so you can boil your tea kettle in 35 seconds, but other than that very few household appliances need anywhere near that amount of power.

    So the result is a cell phone charger, which at the very outside is pulling 20 or 30 watts, is plugged into this giant ridiculous monstrosity capable of supplying 3000+ watts. And in reality the only appliances that use anywhere near that much are cooking appliances and space heaters.

    Meanwhile the US NEMA 5-15 is good for 1800 watts, plenty to run almost every household appliance, with the longer ground pin and an appropriate outlet it supports tamper resistance shutters, the thin flat pins resist the insertion of foreign objects into the outlet, and you can fit many outlets in a small space.
    And it doesn’t destroy your foot when you step on it, as a nice bonus.



  • Nobody knows what to do with it because it’s proprietary and requires a license. If it was not encumbered, windows would ship with a decoder built-in for free and nobody would have a problem. If Apple devices didn’t use it by default, no one would have a problem because they just wouldn’t use it for anything ever.

    If Apple got sick of paying the fee, they could switch to AVIF or JPEG XL or anything else. It wouldn’t be hard, just bake native support into the next OS of everything, and have the next iPhone take pictures in that format by default. The rest of the world will catch up right quick.

    Actually come to think of it I’m kind of surprised Google doesn’t do that. Make the native Android camera shoot in AVIF by default…


  • Yeah but look at the AV1 hardware support matrix. A lot of current mobile silicon supports decode, not nearly as much supports encode. To have AV1 truly replace MP4/MP5 a hardware encode is necessary so you can do video calls in AV1.

    The one who could really make this happen is Apple. If they decided to move away from MPEG-LA and embraced open codecs (AV1 / VP9 / Opus / FLAC / AVIF / JPEGXL / JPEG2000), supporting them in software, hardware, and their services (imessage/ichat/facetime, music store, video store) that would single handedly push the industry.

    They did that with HEIC- before iPhones switched to HEIC by default nobody bothered with the encumbered format. Now it’s become de facto standard. That SHOULD have been something open like AVIF, JPEG XL, etc.
