    I've tried to trade in plank time recently, everything went smoot, except for the stock exchange that disapeared just after a few transactions.

    By the time you had your 8MHz 8086 with 640kB of ram, I was stuck with a 4MHz z80 machine, with 64kB if ram. Commercial barriers suck.

    "How long since Newton discovered the nature of laws of gravity and inertia did it take man to reach into space?"

    To reach space it took a long time, but from Newton definition of something measurable called "force" to the design of machines that could be reliably produced in large amounts, starting the Industrial Revolution it took less than one generation.

    That is not restricted to science reporting. Things are comming to a point where blogers are more trustworth and informative than the professional press. At least most bloggers will link to their reference data.

    There is plenty of evidence that hysteresis is a real phenomenum. It may not be cost-effective, but that is a function of how valuable is your data for the people trying to read it, so it varies with who you are.

    Why not play it safe and make it impossible to recover the data, instead of just not cost effective?

    that cat/dev/urandom > /dev/sdX is exactly what doesn't work with SSDs. Try rm -rf *, that the current article is claiming to work quite well.

    Or, if you are really paranoid, repeatedly do cat /dev/urandom > FILE_IN_SSD after you do rm -rf *.

    That depends, is regedit scriptable? I don't see any problems with the GUI tools running without prompt. Are you afraid the user will open those tools and make some bad changes? You really want a confirmation dialog, altought those are mostly useless (as is UAC).

    Now, about the command line tools... There is no way they'd work with prompts, so I guess they should be whitelisted too. Makes one wonder if the UAC is enough protection for a computer, doesn't it?

    Yes. And on digital equipment that is just when you won't need any kind of regulator.

    Hum? Kepler's laws do not apply to galaxies. Everybody knows that, and that's why people came out with dark matter. Also, altough the mass distribution of an spiral galaxy isn't very similar to a point mass, eliptical ones are quite well approximated by a point.

  11. Re:McAfee does not work on Linux!! on Intel Completes McAfee Acquisition · · Score: 1

    For #1 you can use Wine. Some virus are happy to run on it. For #2 there is no solution, McAfee antivirus works by making the virus unable to run, not by detecting and removing it.

  12. Re:Another Historical Bad Move on Intel Completes McAfee Acquisition · · Score: 1

    Why are you assuming that Intel wants an tivirus that actualy runs fastly? They have much more to gain by getting a popular software, making it run faster on Intel processors and slower on everything else.

  13. Re:Just freakin' wonderful on Intel Completes McAfee Acquisition · · Score: 1

    Wait untill the antivirus becomes free, so it becomes the first choice of several people besides your company. Also, wait just a bit more, until it becomes "optimized" for Intel processors, and makes every AMD computer stall worse than it does now.

  14. Re:Almost worth it on Intel Completes McAfee Acquisition · · Score: 1

    Except that the first thing a virus do is removing the antivirus software. Making it harder for the USER to remove it does not make it harder fow a VIUS to do so.

    More like: Gosh, that AMD processor really blows, it can't run anything properly, let's go back to an Intel one.

    The same reaction people had when Intel made their compiler generate code that was slow at the competition.

    Well, they could "optimize" the software so that their chips will appear faster, and no their competitors.

    But no, Intel would never do such thing...

    So, AMD will have to close a deal with one of those smaller AV sellers, and offer free licences with each of their processors (or maybe just one expensive line)? It is really cheap to defeat that marketing campaing, and with nothing near $7bilion upfront costs.

    Several people even pay for software that display warnings on their PCs when an application tries to do something weard. It is not a new concept. What UAC did wrong is that: It complains about things that it shouldn't; It has no pre-approved list of software, so the tools that come with Windows show it; There is no way to whitelist or blacklist an application, so it displays the warning every time the user do anything.

    See, as most things on Windows, it is bad because of implementation, not concept.

    The idea of using a linear regulator to save power is quite funny...

    Ok, it could lead to a linear reduction of power, since the processor will have quadratic savings, and the regulator linear increases. But it is still funny.

    They do that often. We get tons of people complaining that the cloud isn't reliable (mylself included), some people arguing that the cloud is more reliable than most PC out there, some people arguing you should have a backup, and some people arguing that Hotmail is crap and asking if somebody still uses it.

    Well, the only difference I can see is that there is nobody arguing that gmail is crap and asking if somebody still uses it.

    The entire problem starts when your HR department translate a "must be able to learn XX, YY, ZZ...." into "knows XX, YY, ZZ....". And the problem is sudenly yours to deal with, that is the point of HR departments, they mess up, and you are the one who must clean things. So, knowing that they'll mess things up if you just send them a list of requirements, you'd better tell them the truth, that you want somebody who can learn new things.

    To be fair, Brazil isn't also seeing what you claim. Our governemnt is just discovering that giving trade training to people is better than living them uneducated or making they go through the normal hight scool (we don't use that exact name, but it's the same). There is no movement against university level studing here.

    People that go through trade training normaly do better even at the university (don't know if it is because of selection bias, differing qualities of the school or something inhrerent to trade training), and that is one of the reasons claimed for them.
