    I dunno... We already have enough power to destroy most of the Biosphere, improving that power to destroy the entire planet can not be much worse.

  3. Re:Dividends? on Yahoo CEO Jerry Yang To Step Down · · Score: 4, Insightful

    If the companies don't issue dividends, the only reason to buy its shares is to sell those later, at a profit. That is a Ponzy scheme, it works on times of inflation and that's all, without severe inflation, if fails. Now, when the companies issue dividends, they can be avaliated on a P/E basis, and bought because of those dividends. There is no need to resell the stocks in order to make profit. That is a stable market (that can become a ponzy sceme sometimes, but doesn't need to be one).

    That the US government encorages the first, and not the latter, tells a lot.

    "Nobody is going to donate millions of man-hours to write the software for the F-22 out of the goodness of their heart."

    Nobody would do that, but somebody could quite well exchange that amount of men-hours worth for a piece of software that they own. People currently exchange bilions of men-hours worth for software that they can't own, why won't they invest on a better deal for them?

  5. The trademark problems don't make Firefox non-free on Stallman Unsure Whether Firefox Is Truly Free · · Score: 3, Insightful

    You can always replace the logos and distribute the same software you got, so, it is not Firefox that isn't free, it's the logos. There are packages where everything is free, but on Firefox, just the software is free.

    That, of course, doesn't make the problem less anoying to distro makers.

    That step 3 is quite hard to guess, anything that I can think of will lead to "Profit!" at the step 4.

    With that in mind, there is quite probably some fraud going on at this organization accounting. Where is it based? The police should be interested.

  7. Re:what for the CPU? on AMD Banks On Flood of Stream Apps · · Score: 2, Informative

    "It's not really a graphics cards anymore if you're doing general processing on it."

    It is still capable of hight speed rendering, so it can still be used as a GPU.

    "Why not just put that horsepower on the CPU?"

    Because the processors at a GPU are simpler, it is way cheaper to add power there. Also, there is nothing stoping AMD to add transistors at both, since they are at different chips.

    "Have AMD forgotten that they're still a CPU business?"

    They are also at the GPU business, and this chip is on both.

  8. Re:The future of Computing is in... on AMD Banks On Flood of Stream Apps · · Score: 1

    People don't "need" it only because they don't have it. If you are a gammer, think about this chip as a very flexible physics processing unit, now if you were a home investor, you could think about it as an at-home market simulator. Of course, if you are doing any kind of CAD, the uses are obvious, as are the uses if you are doing any kind of image (or movie) manipulation. Of course, if could be used simply as a GPU (but more flexible, allowing some interesting optimizations), but the other uses are just too numerous.

    Also, it can lead to lower power consuption if you are able to turn your main CPU partialy off and send the floating point heavy work to this one.

  9. Re:I for one... on AMD Banks On Flood of Stream Apps · · Score: 1

    That's normal. Advances in consumer hardware do take a long time to develop. It's risky, needing a very elaborated business plan, research is slow, since everything must be checked several times before it is tried and most of the times it needs modifications on manufacturing plants, what takes a lot of time.

    Poeple say that normal developing time for VLSI is around 7 years. I can't know if that holds today, since I'm not on this market, but on the past I've seen several examples of that.

  10. Re:...and so? on AMD Launches First 45nm Shanghai CPUs · · Score: 1

    "Okay, that's marketing talk. I think that at virtually *ANY* presentation of a new CPU in the last twenty years someone had said that."

    Decreasing the feature size has always leaded to big improvements on top performance, performance/watt and price on the past. I'm not saying that this trend will continue on the future, but it still hods for 45nm.

    "Even for middle business servers, we live with two 8-yrs-old Sun machines which are more than adequate for keeping up all the services we need internally."

    I see... You use neither the MS plataform nor the newest enterprizy technology at your company. I wasn't expecting you to understand such things on those circunstances.

    If by "more of the same" you mean better, cheaper and less power hungry CPUs, well, I guess that could work for AMD.

    You'd get my total support. The State isn't your nany, be responsible if you want your life to go well. I'm not an libertarian in any way, but prohibinting things just because they are dangerous to the same person that chooses to do those things is stupid and harmfull to everybody.

    Now, most chemical regulations are there to make drugs harder to create. You can read the above paragraph again, now thinking about drugs, but, anyway, prohibiting chemistry products is so unnefective that it makes me suspicious if it is really about drugs or about supporting the established companies by harming innovation.

  19. Serious composition on Word? on Windows 7 Benchmarks Show Little Improvement On Vista · · Score: 2, Insightful

    That is a joke or what? Come back at the later stages of composition, when you have some real experience.

    In case you want to listen, I'll tell you what'll happen. Word featureset becomes absolutely irrelevant after all its bugs start appearing and bitting you. Open Office, while less featurefull is functional, so you'll experience the same productivity from the beggining to the end of the composition.

    Anyway, both are bad. If you really care about your productivity, you should learn some good document editing software, like LaTeX, for example.

    ClamAV runs quite well at Linux too. Why use a ported software when you can have the original?

    Also, if you have a SMB share, take a look at clamfs. It works like "-o bind", but runs clamav on everything that is written. You simply mount a protected fs somewhere and export this one, instead of the original dir.
