  • World's fastest Flash memory developed: writes in just 400 picoseconds

    跳过

  • 1 bit / 400 picoseconds is 2.5Gbit/s, or 10x slower than a 1-bit GDDR7 bus (which the 5090 runs at 28Gbit/s * 512 bits).

    To be fair this is non-volatile memory though, so the closest real comparison might be Intel Optame. The speeds actually seem somewhat comparable to DDR5, though even that is starting to run in to physical distance and timing issues. The real questions will be around density, cost, and reliability.

  • China scientists develop flash memory 10,000× faster than current tech

    跳过

  • That's pretty much my understanding. Most of the advancements happened in memory speeds are related to the physical proximity of the memory and more efficient transmission/decoding.

    GDDR7 chips for example are packed as close as physically possible to the GPU die, and have insane read speeds of 28 Gbps/pin (and a 5090 has a 512-bit bus). Most of the limitation is the connection between GPU and RAM, so speeding up the chips internally 1000x won't have a noticeable impact without also improving the memory bus.

  • Tesla odometer uses “predictive algorithms” to void warranty, lawsuit claims

  • Oh perfect, that means I can resell this Tesla I've been using and abusing for dyno testing and other stationary things as having 0 miles driven! /s

  • LG TVs’ integrated ads get more personal with tech that analyzes viewer emotions

    跳过

  • I've seen this linked before, and unfortunately the specs are very mediocre on their TVs. I don't know how they can claim a TV is HDR when it has a meh contrast ratio, no dimming zones, and can't even do 100% of the sRGB color space.

    I don't know how much of the price of other TVs are subsidized by ads, but these Sceptre TVs are pretty bad value when looking at panel specs alone.

  • Chances are they'll have some antenna line going to the edge of the TV. The box on the back of the TV already has a bunch of shielding over it inside. If you were to go to the trouble of opening the TV to find it, you may as well disconnect the antenna and ground it so there's no chance of a signal.

  • The US specifically does spend tax money on foreign aid (or at least they used to). I have no problem with that. If you're struggling to get by, then you should be paying effectively no taxes. If that's not the case, then we should be fixing that, not cutting funding to things that make the world better.

    As for the fee suggestion, a library does not charge for entry or for every book. There is a "free tier" that everyone can use as long as you return the books on time. You only charge the people making too many requests to make sure the service stays available to everyone.

  • If it has value to a larger community, the larger community should be able to fund its operation.

    Up until very recently it seemed perfectly reasonable to fund this sort of thing with taxes, because it benefits everyone even if they're not directly using the database. An open source developer probably isn't going to pay to look up vulnerabilities in the open source dependencies they use, so the database being free makes software more secure on average.

    What is wrong with having free public services? If someone is abusing it, block them, or charge fees like a library.

  • For NASA, data types don't matter when you're programming Voyager 1 and 45 years later it gets hit by an energy burst causing 3% of the RAM to become unusable, and it's transmitting gibberish. It's awesome they were able to recover it.

  • This still isn't specific enough to specify exactly what the computer will do. There are an infinite number of python programs that could print Hello World in the terminal.

  • Based on some rough calculations... no. A precision of 0.0000000000001 ohms is 1000x less than the resistance of 1um of copper with a diameter of 1cm (A piece of wire 10,000x wider than it is long). I'm sure a few molecules of air between your contact points would cause more noise in the measurement.

  • This is exactly how high precision resistors are calibrated. A laser is usually used to notch out bits of the resistor to tune it after it's made.

  • What the "middle class" can afford has changed quite a bit in the last few decades. Owning a home is arguably "upper class" at this point. The median US income was only $80k in 2023. Pentions are also getting increasingly rare. What used to be considered middle class is now struggling to get by. Middle class is defined by the income of the middle third of the population, not by a particular lifestyle.

  • I agree with this, but I don't think we'll ever be able to have that again. AI slop is drowning out all the genuine content regardless of monetization. What's the incentive to put hours of effort into something if nobody will ever see it because every hour another 1000 AI versions were generated and they're all "close enough" to fool someone not paying attention?

  • I've seen pretty much the same thing happening in the programming space. In another 10 years there's going to be a massive shortage of senior programmers who are capable of doing anything more complicated than the AI, and able to sort out the messes everyone's creating with it.

    All the companies not wanting to hire entry level programmers right now is also a big problem for those starting now. I can only hope companies realize AI is not a replacement for a human's learning ability.
