  1. Re:Oh not the we're to big to fix it defense on Google Researcher Issues How-To On Attacking XP · · Score: 1

    Well, there are plenty of countries where Google could sue Microsoft for using that code... But on any country that I've looked at, doing what you said would be a crime and would get no money to Google.

    Oh, no. Gravity's caused by heat!

    But, ok, if it is caused by heat, it may be due to eletricity, you have a point... Or entropy, of all weard things, entropy is the worst ofender, so it MUST be entropy.

  3. Re:ISP accountability on Botnets Using Ubiquity For Security · · Score: 1

    Yep, I misreaded it. When you said "asks you to contact support for further assitance", I instinctively assumed the support was paid. I can think companies may try to satisfy their customers, but ISP doing so is such an exotic concept, I didn't grasp it at first. That is bad :(

  4. Re:Too late? on HP Gives Printers Email Addresses · · Score: 1

    Well, ok that is the market they want to cover. But I disagree that it has any measurable size. First, you'll have to have your PC and printer turned on, that is messing with a PC. Then, you'll have to discover that email address, and mess with a phone (what is harder than messing with a PC) by sending the email. Given that you are in front of your PC (required for turning it on), why don't you just plug the phone and print the photo?

    Now, I guess the reason mobile devices don't normaly come with printer drivers is that you don't carry your printer with you. Taking a picture far from home, and sending it home for printing isn't very compeling. One'll probably want to have the printed document NOW. That can't be done. Obviously, somebody will find a use for printing things at home while far away, it is just not a big market, and can already be filled with current printer and some simple software right.

    Your email address is a good initial bet. It is public, you know.

  7. Re:That may have been said, but .... on Where Will Your Next Gadget Be Made? · · Score: 1

    "hey also tend to make so much product, it starts making economic sense for them to automate/mechanize all sorts of processes that allow hiring cheaper labor (employees who don't need as many skills or as much intelligence, because they're pressing a button or pulling a level repeatedly, instead of *understanding* how to do whatever process happens as a result). That leads to a lot of low-paying jobs, vs. a relatively small number of higher-paying ones."

    You have the consequences of automation exactly backwards.

    First things first, there is a obligatory xkcd.

    Now, that doesn't beat a nice wonder through a library, where you can look for several books and learn much more deep things. But that isn't a problem, since the library is still there, we now have both.

  9. Re:Call me dumb, but... on Adobe Warns of Flash, PDF Zero-Day Attacks · · Score: 1

    The DLL is part of Acrobat Reader. I've never saw a Linux that ships with Acrobat, but it is available for most of them (on some it is just a click away). Anyway, very few people do use Acrobat on Linux, unless you are one of those few that got out of your way to install it, it is not an issue.

  11. Re:Yeah! on AMD's Fusion Processor Combines CPU and GPU · · Score: 1

    If you can replace dot product for any other operator, you can do almost all image processing and computer vision too. And now, that I'm thinking about it, operational research too, and most of numerical calculus.

    That means, it will be a killer for anything besides what normaly runs on a desktop. AMD will still have to wait for a good application.

  12. Re:Moving electrons on AMD's Fusion Processor Combines CPU and GPU · · Score: 1

    Well, I'm not the GP, but he probably meant power consuption. Adding buffers do increase the power consuption (and big buffers, the ones needed for I/O have big consuption). Also, you are right, that it will increase latency, but that can be pipelined into a non-issue in a lot of cases (I don't know if GPUs are one of them).

    Not yet mentioned is the problem of clock synchronization. In order to deal with an external bus, that the size is unknown by the chips designers, you need a logic* chain of buffers. Those buffers could be small, not increasing the power consuption too much, but they must be numerous, making the latency problem worse.

    * You don't need several buffers. Just 2 of them arranged in a way that the signal passes from one to the other several times will do. The more logic buffers you have, the smaler is the chance of getting an wrong reading. The less physical buffers you have, the less you can pipeline them, but the smaller is the power consuption.

  13. Re:Oscillation and the conservation of energy? on Chameleon-Like Behavior of Neutrino Confirmed · · Score: 1

    Anyway, you shouldn't be able to measure that energy lend over time. Every time you look at, the energy must appear to be conserved, all you can measure are consequences of the particle having extra energy on the past, but not anymore. So, the uncertainty principle can't explain the neutrino changing. It is probably better explained by it losing some kynetic energy (then, what happened to momentum, did it interact with matter?).

    Humm. No, the average ratio MUST be 1.0. Otherwise there are ghost computers downloading or uploading things on your network.

    That is not to say that you shouldn't encorage people to get a ratio of 1.5. Only that, as you said, some people will have a reatio of 0.5 because of that.

    $1500 is a reasonable punishiment. Asking people to pay them the $1500 or spend $10,000 on court to discover if they are guilty is more like extorsion. Well, I guess it is not extorsion by the letter of the law, because for the Law, everybody have access to the Justice. The problem is that it isn't true.

    So, we have to fix the Justice. Still, it is easy to blame the ones exploiting the flaw, instead to the ones possessing the flaw.

    Let's keep things on perspective. That is quite a small industry, the average person gives them very little money. It is just that they are a kind of thugs specialized on making noise, and most of the noise appears on areas that we are interested on.

    Taxing buy and sell orders that are too close together would also apply a low pass filter to the market, and will not create moral problems by denying information to the traders.

    A tax that is of 70% - 80% of the price difference for orders that are separated by 1ms or less, reducing linearly to 0 to orders that are 1 minute apart could do the trick ;)
