  1. Re:Blocking up the fail whales blowhole on Windows 7 To Be 256-Core Aware · · Score: 1

    "Yes but once you go past 64 it probably makes more sense to cluster several boxen rather than put all your cores in one basket."

    You are missing the point here. Moore's law implies that the number of cores on the most cost effective processos will keep going up, so we'll cluster 256-cores machines at future, just like we cluster 64-cores machines now.

    "...now that they have a stable, solid kernel..."

    Yes, they have. But I'm not sure the hardware manufactures will rush to port their drivers to NT4.

    Falcon's Eye hides some precious information, and have a quite boring music. My favorite is the QT frontend, there are mnemonic icons for different beings, even from the same letter (but the green mold looks exactly like the linchen what is bad for metalic weapons) and menus for the not very common commands (but I'd hope they fix #c, that only works if accessed by the menus).

    "So, the best for both parties is to abandon DRM."

    Yes, but it is not better for the DRM provider, and this one is the party with the hightest publicitary* spendings

    * Publicitary spending is composed by golf sessions, strip clubs and old plain bribery.

  5. Re:Little new? on BBC Brings DRM-Free Content To Linux Users · · Score: 1

    No way anybody would say that 1-way encryption (AKA hash) is immoral. But DRM is not about that, DRM is about granting access to YOU read the data, while denying access for YOU to read it. Giving access to nobody is quite easy, giving access to some specific person is a solved problem, but giving access to the same person you want to deny access can't be solved.

    In related news, on Soviet Russia DRM gives YOU access to the data while it denies YOU access to it! Hey, I never tought I'd ever repeat that meme :p

  6. Re:Sounds good, but MD5 et al. still have a place on Now From Bruce Schneier, the Skein Hash Function · · Score: 1

    "I'm not a cryptographer"

    Well, thank God or that. First, MD5 is not broken the way you say it is. Yes, it is broken, but you can't just create a string that will have a wanted hash. Maybe you'll can at the near future, but you can't do that now.

    Second, salt won't save a broken hash. Salting will protect you when you use a (unbroken) hash function against a big set of data. Without salting there is a big chance of any random value being on your set of hashes. A colateral effect of salting is that it will make dictionary attacks a bit slower (avoiding the use of a rainball table), but that is not very important, since it is only a proportional speedup.

    Finally, MD5 is quite ok for checksums. It will make sure your download is not corrupt and, being as fast as it is, will not be a burden to your system. That new Skein algorith does look better, but there is no hush to replace MD5 here.

    Now, I'm not a cryptographer either. But I do know a thing or two.

    "It is odd that he's had multiple attacks while I've had zero..."

    No, it's not odd at all. I guess that if people did go around showing your checks to everybody they meet or maybe even posting them to the web, you'd have plenty of atacks too. Instead, people probably choose to cash your checks, so you don't have this problem.

    HTML is extensible, you just use the damn tag and if somebody cares he will implement a browser capable of displaying it :)

  9. Re:Color Me Confused on Microsoft Joins the OpenID Foundation · · Score: 1

    Everybody that has a business plan other than showing you ads while you log on want to be a consumer.

    When OpenID was a new and untested thing, nobody working on unrelated projects had heard about it, so consumers didn't start using it. At the same time, people working with OpenID knew it existed, so providers started appearing. That is normal. Now that it is a little more known, there isn't a lack of consumers anymore.

    Ok, except for the lobster, you just described brazilian internet. There are 2 such trunks, both passing throug universities without any kind of redundancy (both are not redundant, they just serve different areas).

    For the same reason that they flocked to IRC, it's the same happening, half a generation apart.

    Coding isn't an essential aspect of everybody's life. Being out of prision and defending against some extorcionist that wants all your money is.

  13. Re:Hmmm... on Attack Code Found For Recent Windows Bug · · Score: 1

    Well, you probably don't use a Debian based distro too much. To get a stable reasonably secure (known bugs out, most common DoS attacks out) and fast for the most common situations, you simply "aptitude install apache2".

    If you have a less common situation, you may want a different apache2 package, there are some other ones that differ on the configurations. Now, when you have a completely unusual situation, then you'll need to mess with apache configuration or maybe even compilation, but don't assume that an instalation is unreliable or slow just because the admin didn't work hard on it.

  14. Re:MS Gets it right? on Microsoft Unveils Browser-Based Office Apps · · Score: 5, Informative

    It's an extension of Office in licensing. That means, it is a completely unrelated app, that is browser based (that means, it will also be broadband-dependent) that will only be licenced for your use if you brought a licence of Office.

  15. Re:Out of primary colors already? on Microsoft Announces Windows Azure, Cloud-Based OS · · Score: 1

    It shouldn't surprize you that Linux has already used all primary colors. It probably also use the secondary and tertiary ones, as it probably also used a big chunk of animal names.

    When you have several thousand different names, you get to use lots of things.

    "they've made it a point to explicitly say that supporting rails, Python and PHP is on the roadmap...I'm not sure that a completely new service will necessarily take a wrong turn, especially if compatibility with the popular web application environments is a stated goal."

    Just way until they extend Rails, Phython and PHP, then you'll see where all their incoherent complex underdocumented and nonfunctional APIs came from.

  17. 'Cause it IS a trap on Microsoft Announces Windows Azure, Cloud-Based OS · · Score: 1

    Well, it almost always is a trap. I can't remember one single hystory about Microsoft doing something good that was marked with itsatrap (AKA all of them) that wasn't. And if there were a few such cases, you can bet that the false positive rate of the marking is comparable to medicin examinations.

    There is no way one can do "cloud computing" securely. Not Microsoft, nor Debian. It is cheap, and flexible; not secure

  19. Re:Not this kind of memory on Storing Qubits In Nuclei · · Score: 1

    There is another comment down there also pointing quantum error correction, if you reread my post you'll see that I talk about it. It isn't obvious (at least for me) that one can apply quantum error correction on that system, by the same reason that it isn't obvious that one can create a quantum computer from it.

    I guess that if the researches tought that it was obvious how to apply such error corrections, they'd have cited that, so I assume nobody knows how to do that yet. Note that I pointed that somebody may extend the time with error correction in the future.

  22. Not this kind of memory on Storing Qubits In Nuclei · · Score: 1

    I bet that refreshing a qbit will face all kinds of problems... More specificaly, the uncertainty principle forbids refreshing qbits, unless you want them to behave like clasical bits.

    A computer based on this would have to make the hole quantum calculation on 1 3/4 seconds, all the way into a classical result. That would be enough to break RSA if there was a big enough computer, but I guess that isn't enough for everybody. Also, I don't know if it is possible to couple several nuclei and create a computer out of those qbits.

    Anyway, that is an awesome result. Maybe people can create some error corretion and increase that time, and maybe somebody already knows how to couple nuclei. Since I am not a physicist, I don't know about the state of the art.

  25. Re:Hence the reason for the buildout. on Australia Developing Massive Electric Vehicle Grid · · Score: 1

    Ok, but using some kind of flow battery would make a lot of sense here. This way, the eletricity producer is the one that charges the bateries (the slow step), and the charging station simply exchanges its contents (what is fast).

    It only makes less sense to do that with carbon. Ok, we'd reuse the current infra-structure, but there are all kinds of inefficiencies in getting it from the air, turning it into hidrocarbonets and using it at the final destination. I guess some metal-oxyde would be great here.
