  1. Re:Efficiency. on Who Is Liable When a Self-Driving Car Crashes? · · Score: 1

    Yes but the self driving car is is unlikely to suddenly develop a conscience and commit deliberate vehicular homicide. Just because someone is killed in a vehicular accident even today does not mean someone else is guilty of a criminal offence and is off to prison.

    If the self driving AI ran out of options and was unable to prevent a death, then it will be bad luck. Insurance will pay out in the same way it does today. If the self driving AI is causing less accidents than humans which lets be honest is not a high hurdle then using a self driving car will lower insurance premiums.

    If the law is really getting in the way then it can and will be changed. Personally I can't wait till the day I can buy a car that will drive me about. In fact it is the only thing that would persuade me to buy a brand new car rather than one that is a few years old.

    Anyone doing embedded on x86 and is worried about memory is doing it all wrong anyway. The embedded systems that are memory constrained are ARM and MIPS not x86.

    No it won't because it 20-30 years we will be able to do gene therapy to "grow" or "regrow" the stereocilia and hence cochlear implants will be considered as barbaric as medieval blood letting. Consequently the data will only be of obscure historical interest.

    I suggest you do a search on "dongle emulation". There are solutions which admittedly cost $$$ that allow you to ditch the physical dongle and emulate in software so you can virtualize the machine it is running on.

  10. Re:Used to design HDD's on For First Three Years, Consumer Hard Drives As Reliable As Enterprise Drives · · Score: 1

    Really, so where are the home drives with a SAS interface and DIX/DIF? So I pay extra for enterprise drives because I want my drives dual ported.

    Also when it comes to 2.5" drives I can tell you know the bog standard laptop drive is most definitely not rated for 24x7 operation. So yes you can build a low power home server with one, but don't expect the drive to last more than 18 month unless you fork out for the enterprise rated 2.5" drives which interestingly require a 12VDC supply rail to spin up and are 15mm deep rather than 9.5mm or possibly 12.7mm.

    So I don't know when you used to design HDD's but you are talking rubbish.

    That's the thing you where cutting corners on the hardware. Buy the *RIGHT* hardware and get a *GOOD* DBA and there is almost no problem you cannot solve with a real RDBMS.

    Let's put it another way the hardware for random healthcare exchange is a rather small portion of the budget. So you can dick about with a NoSQL system but it is a false economy.

    I would further add that a good number of the NoSQL databases seem to be sprouting SQL interfaces.

  14. Re:You simply have to pull the wire.. on Ask Slashdot: Recommendations For Beautiful Network Cable Trays? · · Score: 1

    That's utter tosh. I can name at least two U.K. universities where all new cabling is done with LSZH Cat6, though to be fair the contractors seem to be using Cat6a cable for the last couple of years. However Cat5e has been a no no for best part of a decade.

    I would also add for good measure I did my house in Cat6a a couple of years ago. Sure I did not do full testing so it might not take 10GbT on all links unless it is all re-terminated by a professional, but there is plenty of slack on the cables and I have been careful about adhering to bend radius when running the cable.

    Just because you have installed a million miles of Cat5e does not mean people don't install something better.

  15. Re:When you have a bad driver ... on Is the Porsche Carrera GT Too Dangerous? · · Score: 1

    The pinnacle of driver aids was probably the Williams FW15C back in the early 1990's. Active suspension was banned because it allowed one to corner to fast for example. The for runner of DRS was banned in the 1970's or early 80's after a number of jams caused cars to go off at corners due to lack of down force. Also banning driver aids is a poor way to control costs. The real costs are elsewhere like having separate engines for qualifying and racing, or having a new engine a race, both of which are now banned.

    I followed F1 for many years, it got boring when all the overtaking took place in the pit lane during tyre and fuel stops. Get back to the Mansell Senna action of the 1991 Barcelona Grand Prix and I will start watching it again.

  16. Re:When you have a bad driver ... on Is the Porsche Carrera GT Too Dangerous? · · Score: 1

    Yes but real racing cars have driver aids, unless banned to stop cars going too fast. See F1 for examples.

  17. Re:When you have a bad driver ... on Is the Porsche Carrera GT Too Dangerous? · · Score: 1

    Really, in F1 many of these "driver aids" are banned because they make the cars go too fast. Surely the point of a high end sports car is to go as fast as possible? If it is just to have fun, and public roads are not a fun park, there are plenty of much much cheaper cars that will just as fun.

  18. Re:Never underestimate the bandwidth on How the LHC Is Reviving Magnetic Tape · · Score: 1

    You only duplicate your full dataset for a new backup if you use a brain dead backup system. Back in the real world, real storage and backup administrators use a "synthetic" backup system like TSM and don't do such stupid things.

    Note also that the storage life rated on my LTO tapes is 30 years, like to see a hard drive working after that amount of time.

    Yes you probably do move the data from older to newer tape formats. But guess what with a fully automated tape library you just tell you backup software to do it, and it is all handled automatically for you. Might take a while but it requires no operator intervention. I don't know about other manufactures but IBM will keep supporting a TS3500 for a very very long time, and remember that an LTO tape can be read by a drive two generations newer. Buy an LTO6 tape to day and it will be readable by an LTO8 drive, so in reality still readable for at least a decade.

    All that said if your backup/archive requirements are small and small is probably less than 100TB these days, then tape is not for you.

    That's just a stupid rule, as it would ban for example a mint condition Jaguar E-type which looks far nicer than any recent BMW or Mercedes. Even Enzo Ferrari called it "The most beautiful car ever made". The New York City Museum of Modern Art recognised the significance of the E-Type's design in 1996 by adding a blue roadster to its permanent design collection, one of only six automobiles to receive the distinction.

  20. Re:Power and legacy codes on Warning At SC13 That Supercomputing Will Plateau Without a Disruptive Technology · · Score: 1

    Interesting thought. I guess the answer is that for the small percentage of HPC users that code stuff, they need to keep updating the code as time goes by. So they might not want to learn CUDA/OpenCL etc.

    On the other hand in my experience most HPC users are using a preexisting application to do something like CFD, molecular dynamics etc. For these there are open source applications like OpenFOAM, NAMD etc. that it would make sense for Nvidia to throw engineering effort at to improve the GPU acceleration.

    The 1000 and 3500 core HPC systems I look after both have a GPU component. They are not widely used however at this point in time, though the few users that do use them use them heavily.

    Hum I think I will suggest this to Nvidia at the MEW24 next week.

So only need two crops a year to get a 250 ton per hectare yield which makes it look perfectly feasible to me. If you really work in agricultural research you need to sack yourself!

  25. Re:Physicists know on Most Sensitive Detector Yet Fails To Find Any Signs of Dark Matter · · Score: 1

    That would be nice but actually physicists have only been using Newtonian mechanics to model galactic rotation. Mostly because doing it with General Relativity is too hard, and simulating it on a supercomputer is probably only been possible for the last couple of years, and even then it would take millions of CPU hours.

    The biggest death nail for dark matter is if it makes up 85% of the matter of the Universe how come the solar system is utterly devoid of it? Remember General Relativity can explain the motion of the solar system within the limits of observation, so there cannot be any dark matter in the solar system. Frankly that is not a plausible scenario.

    When physicists have done a full simulation of a spiral galaxy using General Relativity and found that they need more matter than has been observed then and *ONLY* then will I take dark matter seriously. Till then as far as I am concerned it is as real as the aether.
