  1. Re:got a technical question about these batteries on Panasonic Completing 3 New Cell Production Lines At Tesla's Gigafactory (arstechnica.com) · · Score: 1

    Can any one give me technical reasons why small cylindrical cells like this would be superior to pouch or prismatic cells? I always assumed that a good car battery would resemble the form factor of car starter batteries, big rectilinear shapes putting out decent voltage but a shit-load of amps.

    Smaller cells result in more wasted volume and mass but this is not a limitation in a traction application and the greater surface area improves temperature control.

    Cylindrical cells are a lot stronger. Prismatic cells and especially pouch cells more easily suffer from delamination.

    Did I say anything about prosecution?

    Why not ask them yourself?

    https://publications.parliamen...

    Since 1967, homicide figures for England and Wales have been adjusted to exclude any cases which do not result in conviction, or where the person is not prosecuted on grounds of self defence or otherwise.

    On the other hand, the FBI counts all bodies which did not die of natural causes or suicide which makes sense because that literally is what homicide is, killing by same.

    There aren't any degrees out there that goes through required safety standards for automotive programming.

    They used to be the same standards used for industrial embedded design and there are books on the subject of what *not* to do in mission critical systems.

    The trick, as always, is to enable that functionality without simultaneously enabling the vehicles to be hacked by bad actors.

    The people responsible for updating the firmware remotely are also bad actors or soon will be. How do they protect the functionality from themselves?

    Hey, the regression tests on last year's models did not find any problems. Why are we spending money on them?

  8. What does that have to do with anything? If it's a shared computer each person would have to log into their own account. More than likely under their own profile.

    It has to do with giving an implausibly plausible justification.

    Why doesn't Google just come out and say it. They're sucking up every bit of your information to sell to someone. This death by a thousand cuts is so last decade.

  9. Re:They tried to steal the design of the Alpha? on How Qualcomm Tried and Failed To Steal Intel's Crown Jewel · · Score: 1

    Intel got StrongARM from DEC, which became Xscale, before they sold it off. That seemed like a kind of weird decision - at the time they owned the best-performing ARM implementation on the market, but they sold it because they were betting everything on x86.

    Intel was not interested in producing something which would compete with their own x86 processors (until Itanium) so Xscale and the i960 were sold or discontinued.

  10. The DNC made mistakes but they have acknowledged them and are doing something about them.

    The only mistake the DNC is working to fix is getting caught. There have been no changes and no sincere calls for changes which would improve the situation; those in charge want it to be the way it is.

    The Republicans made their own mistake. I expect them to work harder in the future to make sure someone like Trump does not win their primary election. Maybe they can copy what the DNC did successfully.

    Technically receivers cannot be detected - unless they have a leaky mixer or downconverter stage, or if a SDR. a pickup in CPU activity may give a sign. This is how police used to find out if you had a radar detector fitted, for superhets.

    Leakage of the local oscillator frequency from the receiver can almost always be detected even at a short distance. A couple of times I did fox hunts of low duty cycle transmitters where I checked and found the local oscillator frequency.

    The RF amplifier is often added just to suppress local oscillator leakage but it only has to do so to meet FCC part 15 requirements.

    The employees that even suggested such actions should have been terminated on the spot.

    No, termination is reserved for employees who do not contribute to Google's echo chamber.

  13. So let me try to summarize this:

    Somebody at Google said "hey, we could abuse our power for good!" and management came back saying "it's still abuse, so we're not doing it", and that was the end of it.

    Folks did their jobs, nothing bad happened, and everything worked as it should. It's nice to have a story that isn't sky-is-falling panic, but there's literally nothing newsworthy to report here.

    Just like Google is not in the process of implementing custom services to support authoritarian police states. Oh, wait, they are, there is a memo about it, and some employees have protested it by quitting.

    Just like Goggle does not censor search results in favor of gun control.

  14. Well when "do no evil" becomes "for the greater good" or whatever it is now, it shouldn't be a surprise.

    You can do no wrong when God is on your side.

  15. How much of this is slowdown is marketing driven? There's no reason to release a chip that's 50% faster if people are buying plenty of the older chip. You want to spread that out over time.

    Roughly none of it is market driven except for lack of infinite funds for capitol investment. If they could make a chip which is 50% faster for the same cost, then they would have released a lower power or cheaper chip of the same performance which is what they have done.

  16. Re:Moore's law is working more or less fine, thank on David Patterson Says It's Time for New Computer Architectures and Software Languages (ieee.org) · · Score: 1

    Transistors are doubling every 24 months or so, on par with moore's original enunciation of the law, and slightly off the 18 months of his revision of said law.

    He did not even say that and even Wikipedia gets it wrong with his original quote right there.

    The complexity for minimum component costs has increased at a rate of roughly a factor of two per year.

    It is about economics. For a given cost, the number of transistors doubles no matter whether that is due to increased density, increased area, or increased packaging. And this happens even if transistor performance is decreased which has happened several times.

  17. There are more transistors being used, but not within the same space. So while the transistor count has been going up in microprocessors that does not mean that transistor density has been going up.

    Moore's Law does not make any distinction between transistor density, chip area, or packaging. The only thing which matters is cost per transistor which can be lowered through any of these things. This can even come at a cost in transistor performance which has happened several times.

  18. A SPECint graph shared on Quora shows this slowdown starting back in 2005.

    https://qph.fs.quoracdn.net/ma...

    Moore's law is about cost per transistor (integration) and that graph shows it continuing up to the last data.

  19. When your computer is fast enough to do everything that you need to get done in a reasonable amount of time, do you really need faster chips?

    Yes, we need faster chips so we can produce slower software.

  20. The other half of the joke is that async I/O was the big new feature of a recent C# version, which means it will be the hot new thing in Java in another couple of years.

    Java NIO (Non-blocking I/O) was introduced in Java 4 (2002).

    Non-blocking I/O and asynchronous I/O are not the same.

  21. Teach by example. Show me an architecture that would make me want it. With C++ as a platform language, not stupid shit like java, ruby etc.

    If you want it linked with C++ (or C) as C++ is, then you have already failed.

    On the C++ side, how is it that multiplying two INTs produces an INT?

    On the architecture side, why doesn't each register include stateful flags?

  22. It was once revealed to me that for about 15 cents more per tire manufacturers could make tires that could last the entire life of a car. They choose not to for just this reason.

    They choose not to because it would compromise performance including traction which is important for things like turning and stopping.

  23. I'd have to disagree. It's a well known fact none can ever find their 10mm socket.

    I have extra 10mm sockets but am missing 1/2" and 9/16" sockets.

  24. as much as we all hate subscription models from companies like Abode and Microsoft, those subscription models do give these companies more of an incentive to focus on stability, efficiency, and security instead of features.

    Oh yes, the statisical blip that is Londons current homicide rate. For the past 7 decades at least London has had a drastically lower homicide rate than New York.

    It really helps to only count homicide victims if someone is convicted. Maybe Chicago should do that to lower their homicide rate.
