Progenitor of the Weird Knife Wednesday feature column. Is “column” the right word? Anyway, apparently I also coined the Very Specific Object nomenclature now sporadically used in the 3D printing community. Yeah, that was me. This must be how Cory Doctorow feels all the time these days.

  • You’re conflating the tuner with the antenna. The person you replied to, however, is correct including the comment about the digital tuner boxes (which convert to an analog signal for old TV’s) being available for free during the analog to digital changeover back when.

    Any piece of metal will work as an antenna, even for receiving digital broadcasts. It might not work well, but there is no magical difference between a “digital” antenna and an “analog” one, and since digital television is transmitted over pretty much the same original frequencies as analog was, old analog antennae are already quite well tuned in size and shape to pick up modern digital signals.

    You just have to plug your 1940’s antenna into a 2009+ or so television. The antenna itself doesn’t “decode” anything. It just catches radio waves and passes the waveform along to the TV or tuner box. I still use the old 60’s era rooftop antenna that cane with my house, but plugged into my modern TV and it receives digital channels just fine.






  • Retailer who offers one of those 0% financing schemes, here. TL;DR: It’s from processing fees paid by the retailer and punitive interest after the 0% promotional period lapses.

    The lender makes money in two ways. One, a percentage fee is charged on the financed amount, but it’s not paid by the customer. It’s paid by the retailer. For us it is a little under 2%, similar to the fees most credit card processors charge. So as soon as you make your purchase, the bank instantly skims 1-point-whatever percent off the top. You don’t see this, though. It affects the retailer’s bottom line, not yours.

    Two, the 0% interest rate is a promotion which provides specified limited time in which to pay off the balance. If you do not pay the outstanding balance in full by the end of the promotional term, the bank whacks you for a monstrous interest rate on the entire original transaction amount – not just the remaining outstanding balance. In our case this is damn near 30%. Look carefully at the promotional signage and literature. It will always say “0% INTEREST FINANCING!!! for 12 months.” That 12 months is important. That’s the end of the promotional terms, after which you pay aforementioned buttload of interest.

    And then, the minimum payments on the bills they send you are obviously deliberately structured to trick you into failing to pay the entirety of the balance by the deadline at the end of the promotional period.

    If you’re talking 0% introductory rates for general purpose credit cards, the answer is right there in the name. Those are introductory rates designed to entice you into signing up and using the card, but they’re never permanent. Eventually that introductory rate will expire and you will be left with an interest bearing credit card. Possibly a lot of interest. Even if you pay your bill 100% on time every month without fail, the bank still makes money in percentages and processing fees taken on every transaction from every single retailer where you’ve swiped that card. The bank issuing the credit card can continue to comfortably make money even if no one pays any interest, ever.



  • I have never found the Gex series to be “exciting,” even when it was new. Gex was always a shallow also-ran mascot in the time when everyone was trying to recapture that lightning in a bottle without understanding how it actually worked, and desperately trying to recreate what Sonic and Earthworm Jim and to a lesser extent Toejam and Earl had.

    He was marginally less annoying than Bubsy. That’s about all I can say about Gex.

    If I really decide to play some sub-par 90’s platforming stuffed with stilted and dated TV and movie references, my 3DO still works. Yes, really…


  • You should check out an original Famicom, then. Not only are the controller cables only about two feet long, but they’re also permanently affixed to the console. Well, unless you’re willing to dismantle it, anyway.

    It seems Nintendo expected gamers to keep the console in front of them and connected to the TV via a cable running across the floor, rather than our now familiar methodology of keeping the console under or next to the TV and only bringing the controller(s) with you. The limited amount of space in Japanese households may have also had something to do with it.

    Anyway, if you’re a modern western gamer nowadays it’s annoying as hell. Big N made the right choice when they brought the system to the US in not only making the controller cables significantly longer, but also unpluggable.



  • This means that we may face a situation where hobbyists, small businesses, and aerial photographers who make a living with drones can suddenly no longer fly them, but cops will.

    That was always the goal.

    China (and probably Russia still) have satellites that can read the headlines on your newspaper from orbit. The notion that they’d need or use noisy, unreliable, and easily noticed commercial hobbyist drones for this purpose is laughably absurd. Even if they are planning on secretly snooping on the feeds of privately owned fliers, which is probably not actually feasible at scale anyway. How is the data supposed to be transmitted back to China? Magic? Through the cloud via the user’s cell phone data, with no one noticing? Gigabytes and gigabytes of it per flight? I’m not buying it.

    The real reason the US government is so scared of drones is because it will allow the citizenry (i.e., us) to document abuses and authoritarianism in a manner that’s pretty tough to stop with the usual billy clubs/guns/tear gas/water cannons method. Think BLM, Occupy, future climate protests, and all of those sorts of things. Unchecked aerial photography and video that contradicts the Official Narrative from whatever today’s incident happens to be making it out to the internet and going viral would be highly inconvenient, wouldn’t it? Someone can be capturing video of the police shooting protestors or whatever and easily be half a mile away from where the drone itself is located.

    It speaks volumes about the pathology and mindset of American legislators and law enforcement that they inherently see drones as a “spy” technology. That’s because this is exactly what they plan to use them for, and are terrified that someone else might do the same thing to them.

    Well, tough fucking titty.



  • FYI, there is no “better” way to use hydrogen that will result in extracting more energy from it than it physically contains and can be released via oxidation. This is not a matter of “development” or “breakthroughs.” It is physically impossible. The standard enthalpy change of combustion of hydrogen is 141.83 MJ/kg. Period. That’s it. That’s all you can ever get out of it, provided you achieve perfect efficiency (which currently we don’t). Ongoing research is surely working on getting is closer to 100% efficiency, but it will never get past it. You can’t defy the laws of physics.

    Insofar as I am aware all current hydrogen vehicles already use fuel cells to generate electricity and use that to drive electric motors for motive power. No one is burning hydrogen in a combustion engine in vehicular applications. There are some power plants that are doing it, though, mostly as a mechanism for storing and later reusing excess energy generated from other sources. You can go cross-eyed reading up on it here, if you are so inclined.

    There is the notion of the “hydrogen economy” floating around, that is the use of hydrogen as an energy storage and carrying medium – not, notably, as a fuel for actual generation of energy – but it’s pretty certain that outside of some limited applications this will always be a worse deal than just taking the energy in the form of electricity and putting it in a wire.


  • Hydrogen is a dead end. The only company left trying to chase that particular dragon is Toyota, and I predict eventually they’ll be forced to admit that it’ll never work en masse for private vehicles. Ordinary consumers can already barely be trusted with gasoline, which is neither under high pressure nor requires industrial grade refrigeration to keep it in liquid form, and is a lot harder to ignite… The delivery systems for hydrogen are extremely complex and must maintain an absolute 0% failure rate or else somebody will either get blown up or frozen to a pump. Gasoline is at least a liquid and behaves predictably when spilled, and doesn’t phase change instantly when it leaves containment. And a mechanical failure in the delivery system can be mitigated by simply shutting off the pump. You poke a hole in a hydrogen filling system and you’re going to have a very interesting time. Current systems have redundancies on top of safety devices on top of redundancies for this reason which makes them fantastically expensive.

    Hydrogen also has crap for energy density (around 8 kJ/liter in liquid form, compared to 32 kJ/liter for gasoline) and even if you’re producing it via electrolysis or something is a wildly inefficient way to store and transport energy. If you’re going to use electricity to create and compress hydrogen to transport it and create electricity with it later, it is monumentally more efficient to take the electricity and put it in batteries. So you may as well just to that.

    The thing with battery swapping is that it will absolutely require strong government regulation to ensure standardization and fair treatment of owners. Replaceable batteries in consumer devices obviously aren’t a new concept, and before proprietary lithium packs took over everything, every single consumer device was powered by AAA, AA, C, or D batteries which were very well understood by everybody and were – and are – completely interchangeable commodity items that are readily available to this day. That’s the only way it’ll work. Manufacturers will have to be forced to standardize on a set of pack sizes because without oversight they’ll inevitably try to turn everything into a subscription-only walled garden pretty much exactly as you have predicted. But if there is a thing as an equivalent of an AAA vehicle battery (for motorcycles and scooters), AA vehicle battery (for city microcars, NEV’s, golf carts, etc.) and C vehicle battery (full size passenger cars) and D vehicle battery (light trucks) etc., and nobody is allowed to try to make up their own bullshit, then no one will have to give a rat’s ass about battery health, the dealership, lock-in, or anything else. If you buy a used vehicle with a knackered pack in it or your battery gets cacked, you could just bop down to your local AutoZone or whatever and buy a new one. Or push your car to the nearest swap station. You’ll turn in your old one for the core charge. Exactly like how 12v vehicle batteries work now.

    We’ll have to get people used to the notion that, yes, these things will be kind of a battery lottery and you may get swapped in a pack that’s in slightly worse condition than your last one if you go around pack-swapping all the time. But you know, the next time you swap you’ll get a different one again. And you can play already this game right now if you want to – just go buy some fuel in a third world country.
