  1. Re:It has to either be 40% faster or exploit HW on Sneak Peek at Windows Server 2008 · · Score: 1

    But, hotpatching is supported, to a higher degree. (It's also listed as one of the new features in Vista SP1, or really, the support was kind of there, but as it is really a feature developed for the server version the code in Vista RTM was too bad to be used.)

    They support terminal services, from what I can see. The real issue is that .NET is not supported, with all the dependencies that might mean. No .NET means no ASP.NET, no fancy SQL Server features, no PowerShell.

  5. Re:One potential future advantage of AMD's technol on Is AMD Dead Yet? · · Score: 1

    The stated response time of 3 ns is, however, only equivalent to 333 MHz, or 10 cycles at 3.0 GHz. To realize the benefits of shorter trace lengths to compensate for the added latency, the cache volume cannot be increased. It's also harder to share cache between cores, as that's another source of "required" trace length. Z-RAM is very interesting, but it's not obvious whether it can improve over SRAM at all places in the cache hierarchy.

  6. Re:Will they make it? on Is AMD Dead Yet? · · Score: 1

    The Phenom's a bit of a disappointment, and will probably remain so until/unless people start writing much more parallelisable code (until then, Intel's bigger L2 cache more than makes up for Phenom's "true" quad-core design). But AMD are fighting back on the GPU side - the HD 3870 X2 has had some great reviews, and in many games it's faster than an 8800 Ultra for sixty quid less.
    I'm not actually so sure on the "Phenom will be good as soon as parallelism gets better" thinking. The point is that even when you have a shared L2/fast interconnect/whatever, you would have really liked to stay in the L1. Simultaneous writes will mean locks and cause trouble (or added latency, even for seemingly lockfree structures), even if the cache is shared. The point is that good parallelization should not require frequent transactions at high bandwidth between threads, no matter how close together you put them.

    I wonder what the low-frequency observators will make of the fact that the emissions from a body orbiting Sol has remarkable signals in the 50-60 Hz range, and that the linear components of the two distinctive signals changes distinctively with a 24-hour period.

  9. Re:Not so bad, really, except that it's bad... on TR Picks 10 Emerging Technologies of 08 · · Score: 1

    Contrary to what others here have been saying, Dragon Naturally Speaking and similar programs are NOT "Natural Language Processing". They are, instead, language translaton programs. The former refers to extracting actual meaning, of some kind, from the input. The latter means little more than determining what words you said closely enough to perform some pre-programmed actions. The two things are worlds apart. There has been some real progress in the latter... but computers really don't "understand" language any better than they did decades ago. Do you have any specific source for that? I would say that most anything that fits as an ACL paper is also NLP of some sort, or at least that's the current trend in modifying the definition. With the advances of statistical systems in many fields where "real" content extraction was once thought to be the holy grail, the actual difference is blurred. I think that we will define away anything close to strong AI as "something else" for quite a long time, even at the point when it is obvious that the only thing keeping a specific piece of software from being strong would be an arbitrary limitation in input and output.
  10. Re:Cell aging on Major Advance In Understanding Cell Reprogramming · · Score: 1

    Existing cells in situ won't be changed. Injecting these in existing tissue will, supposedly, add into the empty spots of the cellular matrix and so could add a kind of rejuvenating effect. Any attempt to activate telomerase in general in existing tissue is outright dangerous, considering that it only takes a single cell out of a billion to seed a cancer.

  12. Re:So, what's actually accelerated here? on All GeForce 8 Graphics Cards to Gain PhysX Support · · Score: 4, Informative

    I don't think that's the case. Graphics cards work on the same PCI-X buses that acceleration cards probably use lately. They use DMA to communicate with main memory without involving the processor. The VRAM might be optimised for writing, but it should be very possible to do calculations on the card, and get the results back. That's the whole point of the generalised GPGPU techniques.
    Nitpicking: PCI Express is not PCI-X. PCI-X was a derivative of the parallel PCI bus and never found in mainstream machines.

  14. Re:Is this x86/x86_64 only? on Linux Kernel 2.6 Local Root Exploit · · Score: 2, Informative

    As it's all about VM handling, I'm not sure, maybe some platform might give a panic, maybe some will use a different codepath, but it seems to be high-level enough that it is common code for all architectures. However, the only parts that are specific for x86 and x64 in the actual exploit are really the exploit code that's called within the kernel. As it is inline assembler and calling-convention specific, one would need a separate set for each platform. This is just like a user-space buffer overflow needs a specific exploit per platform, although there might be a common bug.

    I think you would be surprised to see what kinds of draconian licensing schemes are still out there for special-purpose (and highly professional) software. It's the same class of products that can get away with a crappy installer and even possibly quite specific requirements of OS, since they have their market and the product, when it works, actually adds a lot to productivity.

    And nothing stops you from implementing that in COM (where the "interface" aspect is very much a part of the concept) or .NET. In fact, that's the way ADO data access worked in Windows, to continue your example. That doesn't magically solve the issue of incompatible DB syntax. I think there were some plans on implementing a version of Gecko that exposed the MSHTML interfaces, but I don't think they ever got close to actually finishing it.

    I thought Mozilla and other projects kept the real public resources (like the bug db) under some limited access, where relevant (exploitable) bugs tend to be locked-down until the fix is released.

  22. Re:What would be the difference? on Microsoft Upgrades Vista Kernel in SP1 · · Score: 3, Informative
    This is in the area of Really Bad Analogies, but bear with me anyway: Windows 2003 was the followup to XP. Quite a few users who got their hands (ahem...) on Windows 2003 think that it is a very solid workstation OS, handling a few situations better than XP. If blatantly ignoring the lack of drivers, XP64 (which is derived from the 2003 codebase) is also solid. More polish went into handling high-load cases and simple bugfixing, things that were never justified to backport to XP. (SP2 carried over some things and added a few, so until Windows 2003 SP1 was released, there were two clear forks again with non-overlapping features.)

    What does this mean for Vista SP1? Well, there should be very little reason to use Windows 2008 as a desktop OS. One could imagine that some geek/pro user workloads (network/disk I/O, anyone?) might be improved. On the other hand, these changes should already be in the SP release candidates, and the reviews of those haven't shown any big changes. A practical concern would be that the platforms should be similar from now on, like in the W2K days. I guess that will make at least some hardware vendor developers happy. Maybe this will also mean that additional hotfixes more acutely needed for server scenarios will trickle down to Vista.

    It's also common in mathematics - Sir Isaac Newton stole copiously from Huygens, Descartes, Hooke, and anyone else stupid enough to let him. Or perhaps not stupid - the only person to resist Newton's claim of ownership did die rather soon after. Ehm, Descartes died in 1650. Newton was born in 1643. As at least Hooke was actively contesting the rights of discovery, I am not sure what you mean by the death reference, as he lived to the age of 67, while the conflict arose far earlier. Newton was not amicable to everyone, but you certainly had quite a bit of hyperbole in your post.

    As x64 eliminated the more rarely used x86 rings (IIRC), and the kernel protection of Vista is most encompassing on x64, it's quite clear that this source was not very reliable. Vista and 2K8 are siblings, but noone (in their right mind) at MS denies that 2K8 is based on 2K3.
