  1. Re:Theoretically up to? on Cray Unveils XC30 Supercomputer · · Score: 1

    It's the number of nodes that can be connected into a single machine multiplied by the theoretical peak performance of each node (implying zero actual communication). The limit on the number of nodes can be limited by a range of things, from how many nodes are addressable by the networking hardware to an #IFDEF on the maximum number of nodes the software is willing to support.

  2. Re:details, details on Cray Unveils XC30 Supercomputer · · Score: 1

    The statement is that the xc30 can _make it_ to 100 PF. Nobody will build a 100 PF machine (i.e., 1600 cabinets, 8x more than Jaguar) with this product line, there will be upgrades before then. 32k sq ft of machine room space and cooling is too expensive.

  3. Re:Unexplained Achievement "The Maker"? on Slashdot Launches User Achievements · · Score: 1

    As far as the total achievements go, I think it is a true sum of all the instances of each achievement. However, next to each achievement, it only shows the most significant power of two in the binary representation. So, if you have 70 +5 posts, it will only show 2^6 next to that achievement, but will contribute the full 70 points to the total.

  5. Re:Nvidia have already open sourced what they can on VIA Announces Open Source Driver Initiative · · Score: 2, Informative

    It's likely that your reinstall on every boot is necessary because your distribution includes several open source replacement drivers which interfere with the one you installed. This can be fixed via adding

    DISABLED_MODULES="nvidia nvidia_legacy nvidia_new"

    to /etc/default/linux-restricted-modules-common , or something like it.

    Anyone who's used Apple products for any length of time knows that the 1.0 release is going to be quite shaky. Remember 10.4.0? Yeesh. The difference between Apple and Microsoft, I think, is that Apple actually fixes it, and fixes it somewhat quickly.

  8. Re:Interesting on $200 Linux PCs On Sale At Wal-Mart · · Score: 1

    Even at the low end, however, image is everything. The gPC is built using tiny components, but put inside a full-size case because research indicates that Wal-Mart shoppers are so unsophisticated they equate physical size with capability.

    That comment is actually quite inflammatory. I'd bet hard money that they never used the word "unsophisticated" when discussing why they made it large. However, the thought expressed by these "insophisticates" is generally true: You can generally fit weaker machines in smaller cases than more powerful machines. That's why there's still a market for the freaking huge Lian Li cases for power users... because some powerful gaming machines require freaking huge cases. And it's why the Mac Mini is in a small case while a Mac Pro is in a big one.

  9. Welcome to Lords of the Realm 2! on 'Neurotic' is Best RTS strategy · · Score: 3, Interesting

    I discovered that a hardcore neurotic kind of strategy worked well in Lords of the Realm 2 when playing with my brother. He didn't care, and would rather have the game over quicker than not, so when we started the game he immediately spent all his resources on getting weapons and a huge army, and within four turns or so had come over and whooped my ass. Every single other aspect of his kingdom was in shambles, but he had the element of surprise, and that's all that ended up mattering.

    I'm thinking the AI would think something similar to me... "Surely he won't try that. If he fails in his attack, he'll just fall over on his own accord in a few turns." Unless he doesn't.

  10. Re:Silly technological overkill on Self-Tuning Electric Guitar · · Score: 1

    Typical floating bridge guitars have a locking nut that prevents the strings from shifting on the tuning pegs when doing more extreme things with the tremolo system. This not only gives you tuning stability, but prevents the strings from shifting into awkward high stress positions that can cause them to break. Therefore, during normal use where the nut is locked, the tuners are not usable to change the tuning of the guitar. You can do (slight) pitch adjustments using microtuners at the bridge, so the "older" tech would be more useful in these cases.

    Yeah, this happens all the time, both with the University of Alabama at Huntsville and the University of Alabama at Birmingham.

    The Dvorak keyboard is more efficient by a factor of 10 and you don't see it taking over the keyboard layout landscape.

    I currently type at least 110 words per minute, no errors. Do you mean to tell me that I can type 1100 words per minute with Dvorak?

    Actually, I'm not aware of a well-constructed study that proves the Dvorak layout as superior. Here is an interesting article on this subject: http://www.reason.com/news/show/29944.html

  15. Re:Hey AMD, A tip for you. on AMD Launches New ATI Linux Driver · · Score: 1

    This is not likely NVIDIA's fault. Ubuntu has various issues dealing with 3rd party drivers that conflict functionally with those in the repository. In this case, the various "nv" drivers conflict with the blobs released by NVIDIA. One way to fix this is to use the nvidia-glx packages from the repositories. The other way, if you have to use NVIDIA's blob, is to blacklist the included nv drivers.

    NVIDIA has long since had a handle on your "latest/nonstandard kernel" problem. It builds its own interfaces to conform to the kernel's.

  17. Re:Applications are more important than the OS on Tales of Conversion - Using Ubuntu at Work · · Score: 1

    At the level you present it, this is not generally true. Office works fine... If the most recent version of office you wish to run is Office 2000. According to the codeweavers website, Word 2003 has "bronze" status, which means: bronze applications generally have enough bugs that we recommend that our customers not depend on their functionality. This isn't good enough for people who use more recent versions of office regularly.

  18. Re:preconfigure on Dell to Offer More Linux PCs · · Score: 1

    In case you haven't noticed, rebooting has to happen fairly often for updates with most linux distributions recently. Probably about once every three times I get updates for Ubuntu or Fedora, I have to do a reboot.

  19. Fidelity of game experience on Behind the Scenes with Harmonix and Rockband · · Score: 2, Insightful

    Why does the drum set have to feel like a real drum set? When looking at, say, the guitar hero controller, did they attempt to make the guitar controller feel as much like a real guitar as possible? The "strum" functionality is just like a switch, as opposed to the sensation of actually taking a pick across a string.

    My point is, you don't have to have an ultra-realistic experience for this game to be fun. It might even help a little if it's a bit less realistic.

  20. System Noise on Shuttle SDXi Water-Cooled SFF PC · · Score: 3, Interesting

    The article mentions a problem that I have had with Shuttle systems all along: Noise. Even though it's water cooled, they found noise to still be a problem.

    If I could be choosy, this is what I want in my typical SFF system:

    - One full size x16 PCI express slot for my big graphics card (that should fit and be adequately cooled)
    - Space for two hard drives in the chassis, along with one optical drive
    - Near silence except when doing something intense, like gaming or encoding
    - Of course, small.

    When will I get such a system!?

  21. On the Compulsory License on RIAA Claims Ownership of All Artist Royalties For Internet Radio · · Score: 5, Informative

    The article is overly inflammatory, adding emphasis to quotations (which the author/editor doesn't claim) to the word "compulsory" in "compulsory license". Obviously, they didn't do much research into what the compulsory license is in relation to copyright law.

    The compulsory license is largely a way of ensuring that, if a content distributor wishes, it can use certain types of copyrighted works in certain ways. An example includes making a cover of a copyrighted song. Usually, royalties are paid to the songwriter in such cases, and you can work out favorable terms to both parties. However, if the parties don't come to agreement, the content distributor can instead agree to the compulsory license and agree to pay said artist based on the published rates. As long as this happens, the original copyright holder cannot sue (because he/she is getting paid as dictated by copyright law).

    In short, this means that you can indeed make a license directly between you and the copyright holder itself. However, if you're going to use the compulsory license, there is a procedure that has to be in place aside from mailing an unexpected check to the copyright holder... There's no proof you paid!

    So, it's a bit different than the article's author paints it. Of course, most wouldn't agree that the copyright holder should be a member of SoundScan in order to get their royalties, but it's an entirely different issue.

  25. Re:Look at FFMpeg on Is Assembly Programming Still Relevant, Today? · · Score: 1

    What you mention is spot on, but there's a specific reason that it's faster to do this. With the various multimedia ISA extensions, which are typically instructions designed to work with small vectors of 3-4 elements, nice speedups can be obtained... However, this functionality is not exposed in high-level programming languages, and it's usually not going to be generated by a compiler, either.

    Also, look at linear algebra libraries. They also use these short-vector instructions deep within the kernels. The percentage of assembly language is very small, but those kernels are executed a lot, so the speedup over ignoring these instructions is significant.
