  1. Re:Let me get this straight on Mozilla BrowserID: Decentralized, Federated Login · · Score: 1, Insightful

    The first issue is fixed simply by the browser asking your permission before it sends your data. The UI can be made in a way that is harder to give permission (at the first login) than just clicking 'Yes'.

    The second issue is real, but is also moot. Everybody uses email for authentication. A few people that can think offer the option of changing your email, others don't. Those same groups would do correclty/incorrectly any authentication method you can think of.

    With the added advantaje that the location of everything changes from distro to distro, and instalation type to instalation type. Up to the point that now files are completely overwritten every time so, if you decided to not even memorize some GUI and got directly to the files you'll still be lost trying to find where is the configuration of the script that updates the configuration file you are trying to edit. Microsoft and its monoculture will never up that one.

    Now, does somebody know how I stop KDE 4 for going into another level and relocating the icons at the notification bar while I'm using them? The fact that the volume is promoted to the right every time I interact with it and some other program gets its place is anoying...

    There, FIFY. The GP has a point, Windows API uses pointers everywhere. If you are doing some hardcore stuff you are probably ok with that, but if you are just doing a GUI, those pointers will hurt. And people don't do much hard core stuff on an atom.

    Yeah, the subject parses as "AMD releases fastest slow GPU". None of the important data is shown.

  10. Re:Performance is what matters on The Fanless Spinning Heatsink · · Score: 1

    I understand what you want. I also have my whishes, like where can I buy a PC sized one? The problem is, they are experimenting with a quite new technology, and thus looked at more general measurements. That kind of table is very usefull, but they are aplicable to a product, not a technology.

    The current device wouldn't even work inside your computer, as it needs a nitrogen bottle. The next prototype they say they'll do will probably have problems with dust... But it is very promissing.

  13. Re:Performance is what matters on The Fanless Spinning Heatsink · · Score: 1

    Turns up the performance of a heat exchanger is a surprizingly difficult thing to evaluate. Maybe you overlooked it, but they made an entire section just about the performance, where they enumerated 3 key metrics of it, and their first prototype is around 4 times more efficient than the other ones at all of those metrics.

    But if you are just wanting to know just how much heat their small prototype moved, yeah it was small.

    Not quite so, they compared their model with new dissipators, that didn't have dust on them.

    You'll still have to create some mechanism to insulate the gap from the surrounding dust filled air.

  18. Re:Fanless doesn't seem to be an accurate descript on The Fanless Spinning Heatsink · · Score: 2

    That "boundary layer" theory is well justified by models and experiments. The lack of a fan does not make it disapear, but rotating the heat sink does make it smaller.

    About dust, it only accumulates over a hight speed rotating surface (where the air speed is increasing) up to a certain amount. That amount is certainly way lower than the dust that accumulates at a static place where the air speed drops. Immune do dust is a justfied simplification, altough a bit over confident.

    Also, I completely agree with your point about the dust accumulating at the gap. That device won't last for long at the real world.

    Except that when you rotate you are not only moving, you are accelerating.

    You can always prove that a program will go on forever in finite time. What you can't aways prove is that it will halt.

    Anyway, the above was quite OT... For securing the governemnt's systems against their users the governemnt can issue some "Right to Read" laws applying just to their computers. It should even have already done that. No overall society control is needed.

    Yep, I'll second AC here. It is up to the company to decide if they'll have profits for that sale or not, the GP didn't set the price. It can very well post some offers that just take away part of their profits, keeping them positive, as they can bet that a highter yeld due to the offer will make the reduced price lucrative. Or maybe it did hope that the GP would like so much that he would return, paying the full price. If it made the wrong bet, well, that happens a lot when betting.

    Personaly, I don't see much utility at ads targeted at buying history. The time somebody is less willing to buy a car/house/television/plain ticket/phone/whatever is just after that person has brought a car/house/television/plain ticket/phone/whatever. Buying habits are much more dependent on the nature of the good than the nature of the buyer, and the dependence on the buyer is actualy much harder to discern than such kinds of schema would imply.

  23. Re:A Technicality: on Banks Find Way To Sell Consumers' Shopping Data · · Score: 1

    Yeah, the customers are being tricked into releasing their information. Yet, that is a completely different situation from their information being released by the bank. I'm not claiming it is moral, but there are two points to consider...

    One is that you can simply not use the service, you'll receive spam but you can just ignore it. If it was so easy to protect our personal information at every situation, most of the people concerned would be quite glad.

    The other is that this method takes away the economical incentive for corporations to use that information in worse ways. They'd hardly simply sell your information if they can get the same amount of money (or maybe even more, since they are actualy renting) with much less PR and legal repercussions.

    Yet, it is dirty. Worse yet because it comes from the banks, a kind of business that everybody has to deal with.
