  • Japan determines copyright doesn't apply to LLM/ML training data

    Jump

  • Um - your examples are so old the copyright expired centuries ago. Of course you can copy them. And you can absolutely use an image of the Mona Lisa without accreditation or licensing.

    Painting and selling an exact copy of a recent work, such as Banksy, is a crime.

    … however making an exact copy of Banksy for personal use, or to learn, or to teach other people, or copying the style… that’s all perfectly legal.

    I don’t think think this is a black and white issue. Using AI to copy something might be a crime. You absolutely can use it to infringe on copyright. The real question is who’s at fault? I would argue the person who asked the AI to create the copy is at fault - not the company running the servers.

  • What? Physical controls? It'll be a touch screen.

  • Clinicians could be fooled by biased AI, despite explanations

    Jump

  • I just don't think that's how this will work in practice.

    What I expect is the AI will provide several possible explanations for the test results. Most of them will be wrong, one might be correct. If the clinician can think of more that the AI missed, those can simply also be added to the list of things to consider.

    Human clinicians are surprisingly bad at diagnosing problems - as soon as we think of something that fits the symptoms, we struggle to think of other problems that would also fit. A lot of time (sometimes years) is often wasted proving the first diagnosis was wrong before anyone comes up with an alternative hypothesis. AI can do a much better job in that specific scenario... but it doesn't mean it can replace humans entirely.

  • Everyone knows exactly where the satellites are and certain (potential) enemies have the capability to disrupt/destroy them.

    A stealth jet is, well, stealthy, which has a lot of value.

    Some artists impressions of the jet don't have any windows and it's believed to be unmanned or at least capable of unmanned flight.

    Also I wouldn't discount the cool factor... the airforce does fighter jet flyovers all the time and occasionally stealth jets too. It helps with recruiting for one thing.

  • Here’s how the EPA calculates how far an EV can go on a full charge

    Jump

  • Honestly it's not even a rough estimate. ICE cars only convert something like 20% of the energy to actual power at the wheel. That means, in practice, range is mostly just about how much time you're behind the wheel. It would make more sense to estimate ICE range in hours than miles.

    EVs are more efficient, so in practice, particularly on long trips at high speed, range will vary dramatically depending on what's going on aerodynamically, which changes dramatically from one second to the next.

  • It’s just irresponsible drivers and Tesla’s own “it’s self driving” advertising ruining it for everyone.

    Maybe if they marketed it as something less than "full self driving" people would be more responsible.

  • Wi-Fi 7 Signals the Industry’s New Priority: Stability

    Jump

  • If your robot moves around, then it needs a wireless connection. And it doesn't really get any more reliable than wifi. I'm certainly not going to outsource that to a Verizon cellular connection.

    And even for things that can be wired - ethernet is far from reliable. Cables are easily damaged or simply unplugged.

    Wifi can work really well, especially with high end networking gear (and not, for example, the wifi access point you get for free from Verizon).

  • The EU common charger : USB-C

    Jump

  • It should be difficult. You need to convince ten billion people to buy new chargers if you're going to switch to a new charging standard and often several chargers per person (five at home? three at work? two in your car?).

    Manufacturing and distributing 50 billion or so chargers only makes sense if your new standard is a lot better than USB-C. And if it is, then it won't be difficult to convince people to move to it.

  • The EU common charger : USB-C

    Jump

  • They definitely exist. But there aren't many devices that are compatible with them - the 240W chargers run at much higher voltage than regular USB.

    Also - only really large batteries (ones that you can't take with you on an airplane for example) are able to charge at 240W without overheating. So there's just not much demand for a charger that powerful. Lower watt chargers are cheaper and smaller and lighter.

  • The EU common charger : USB-C

    Jump

  • The law requires a the industry agree to a "common" charger. Right now, the industry has picked USB but that might change.

    It's up to the industry to figure out technical details...

    But basically it needs to be possible to buy one charger, from any brand, that will "work" to charge any device. That doesn't necessarily mean it will work well... a 5w charger might take 20 hours to charge a full size laptop battery for example... And that's if the laptop is off. Some USB chargers provide 240w... you probably don't want one of those for regular use though - they will be big and heavy and expensive. And a small battery won't charge that fast anyway.

  • The EU common charger : USB-C

    Jump

  • Yeah I think they'll definitely get in trouble for that. Nintendo's official statement that "third party chargers will void your warranty" is pretty clearly a breach of the common charger rule.

    And it's not an empty claim either, some standards compliant third party chargers can actually damage a Nintendo Switch. Nintendo will have to fix that, or else their products might be banned across the EU.

  • The EU common charger : USB-C

  • i’m not able to understand any technical part

    I'll break it down for you - it's a long list but easy to understand:

    • Some cables have four internal wires. Others have over a dozen wires.
    • Some have thin wires, some have thick wires. The thick ones cost more and are less flexible - the main benefit is they can be longer while charging quickly.
    • Some cables have the internal wires wrapped in plastic. Others have them wrapped in plastic then that's wrapped in a metal shield, then that's wrapped in another plastic layer. The latter is more reliable and not just for the cable itself (without shielding, the cable can interfere with other electronics that are near the cable - such as your computer or phone.
    • Some are just ordinary cabling, and some have complex circuitry embedded in the cable to run advanced algorithms to remove noise from the cable - this is necessary to achieve high data rates at long cable lengths.
    • Nearly all use copper cables. A few use fibre optic cables. This can handle even longer cable lengths
    • Some cables are just like "whatever this will do", and others are well designed and carefully manufactured/tested/etc.

    .

    i just want a color : yellow charger/cable go with yellow port. Etc.

    There would need to be something like a fifty colors. The USB standards body is pushing cable manufacturers to use labels that show data rates (gigabits per second) and power capabilities (watts) on every cable. That will help a lot, but for all the other stuff (especially shielding and general quality...) you need to rely on either brand reputation or third party tests. Even then you need to be careful, because the best brands don't put all those features in every cable (too expensive).

    Also unfortunately at 10€ you get what you pay for. The better brands all charge more than that.

  • The EU common charger : USB-C

    Jump

  • Devices (not just laptops) can still have any port - it's just that at least one of them has to be the "common" charger port (as far as I know, USB-C isn't part of the legislation. It has provisions for the industry to adopt something different in the future).

  • Why a kilobyte is 1000 and not 1024 bytes

    Jump

  • Windows and Mac both use KB = 1000. With Linux I think it depends on the distro.

    You're thinking of very old versions of Windows... old versions of MacOS were also 1024.

    It's honestly irrelevant anyway - if you want to actually know how much space a file is using on disk, you should look up how many pages / sectors are being used.

    A page (on an SSD) or sector (on a HDD) is 32768 bits on most modern drives. They can't store a file smaller than that and all of your files take up a multiple of that. A lot of modern filesystems quietly use zip compression though. Also they have snapshots and files that exist in multiple locations other shit going on which will really mess with your actual usage.

    I'm not going to run du -h / on my laptop, because it'd take forever, but I'm pretty sure it would be a number significantly larger than my actual disk. Wouldn't surprise me if it's 10x the size of my disk. Macs do some particularly interesting stuff in the filesystem layer - to the point where it's hard to even figure out how much free space you have... my Home directory has 50 GB of available space on my laptop. Open the Desktop directory (which is in the Home directory...) and the file browser shows 1.9 TB of available space.

  • Why a kilobyte is 1000 and not 1024 bytes

    Jump

  • Nobody gave a fuck until they bought a 300gb hd with 277gb of free space

    The difference was a lot smaller when you were dealing with 700 byte files - it was often a rounding error. Also - you needed two sectors (1024 bytes at the time) two store your 700 byte file, so what did it matter anyway? If you want to get really specific, you actually needed three sectors - because there's metadata on the file... however the metadata will share space with other files so does that count?

    Filesystems are incredibly complex and there's no way they can be explained to a lay person. Storage is and always has been an approximation.

    It's even worse with RAM these days - my Mac has 298TB of memory address space currently allocated... but only between 6GB and 7GB of "app memory" in use (literally fluctuating between those two from one second to the next when I'm not even doing anything but watching the memory usage).

  • Why a kilobyte is 1000 and not 1024 bytes

    Jump

  • Initially the SI prefixes were used and used 1024 instead of 1000

    Only CPUs and RAM use 1024. Floppy disks and hard drives going way back to the 1970's used 1000. In software, both are used depending on the context (and also obviously depending on the software). Most modern operating systems use 1024 for RAM and 1000 for file sizes (in the early days of computing, that agreed upon approach didn't exist, and it varied from one computer to the next).

    @smokin_shinoby's tech school was shit. There has never been consistency on this issue and it's really sad that they failed to teach both numbering systems as they are (and always were) widely used.

  • Why a kilobyte is 1000 and not 1024 bytes

    Jump

  • In terms of storage 1000 and 1024 take the same amount of bytes.

    What? No. A terabyte in 1024 units is 8,796,093,022,208 bits. In 1000 units it's 8,000,000,000,000 bits.

    The difference is substantial with larger numbers.
