  1. Re:Could the article be more wrong? on Jaguar Recalls 18,000 Cars Over Major Software Fault · · Score: 1

    I assume that the brake works an all wheels, though, so even the rear wheels would be stopped by the brake.

    I'd wager if you had to do that you should be driving an automatic.

    Not really. I guess it depends on the car. If you have plenty of torque, you can do a lot with just the clutch. In Europe, engines are typically smaller and only have 4 cylinders. Gasoline engines are quite eager to stall at low RPMs.

  3. Re:Biggest TCP/IP mistake on Vint Cerf Answers Your Questions About IPv6 and More · · Score: 2

    Yes, TCP implements streams on top of messages, but I wouldn't call it trivial. Even though the essence of the protocol is simple, many implementers would still get it wrong.

    Also, the IP message is limited in size, so if you want to implement larger messages, you'd have to split them up into smaller ones. Or, alternatively, it you want to exchange very short messages, performance will suffer. At least TCP protects you from that with the Nagle algorithm.

    But, hey, if you don't like the stream protocol, you can always use UDP.

  4. Re:Biggest TCP/IP mistake on Vint Cerf Answers Your Questions About IPv6 and More · · Score: 2

    That's not a problem, but a feature. It's trivial to make a message protocol on top of a stream, and the stream protocol is easy to implement.

    Streams on top of messages, or one type of messages on top of other type of message protocol is trickier.

    You might warp the rotors, ruin the brakes and lose the treads on the tire

    The tires would be fine, since the brake counteracts the engine before you get to the tires.

    Besides, if you have to enter so many numeric IPv6 addresses that the colon is bothering you, you're doing it wrong.

    Yes, that's what I said will work on a gradual incline. If the hill is steep, you cannot hold the car with the clutch alone, but you'll need some extra gas as well. At least with gasoline cars. Diesels have much more torque, so you can start them on a steeper incline with clutch alone.

    Of course, you could still do it quickly, and you'll only roll back a little bit, but that's considered bad style, and could be hazardous if someone is behind you. Where I live, starting on a hill is part of the driver's test, and you get points deducted for rolling back during the process.

    Well, the article said neither. It says "25 million", which implies 2 significant digits.

    If somebody then makes a big deal out of this precision, and rewrites this as 25000000, we can reasonably assume they mean 8 significant digits, otherwise there would be no reason to make that comment using that notation in the first place.

  10. Re:Give me discrete controls any day on Jaguar Recalls 18,000 Cars Over Major Software Fault · · Score: 1

    I'm not sure it's even possible to create software that does *the same thing* as a discreet circuit

    That would be quite easy. It's the opposite way that's often impossible. Problems that can be easily solved in software are often too complex to solve in hardware.

    Software will be assigned multiple tasks, for reasons unknown

    The reasons are clear: software is capable of solving complex problems for a low price, and customers want those features.

    1. Apply handbrake while keeping clutch pushed in.
    2. Move foot from brake pedal to accelerator.
    3. Slowly release hand brake while simultaneously easing off the clutch, and pushing the accelerator.

    Without a hand brake, you'd start rolling backwards if the hill is too steep.

    On a more gradual slope, you don't need the hand brake. Just release the clutch enough that you can let go off the foot brake.

    When you're trying to solve the same problem, software solutions aren't necessarily worse than discrete circuits. The only difference is that software can solve more complex problems, so that's why software bugs are more common.
