  1. Re:multi core design on Scaling To a Million Cores and Beyond · · Score: 2, Interesting

    While turning intrinsically serial problems into a parallel form would certainly open up a new field it is doubtful that it would be a "a whole new field of mathematics" or did you just like the sound of your hyperbole?

    On a slightly different note; every time there is any article about parallel architecture on slashdot someone raises the problem of inherently serial tasks. Can you name any? Or more to the point can you name an inherently serial task on a realistically sized data-set that can't be tackled by a single 2Ghz core?

    It would seem that we have scaled single-core performance to the point that we don't care about serial tasks any more. All of the interesting performance hogs that we do care about can be parallelised.

    They seem to be a bit flakey in text edit boxes. I'm never sure what effect they will have, sometimes they do the obvious, but sometimes they move the page. Doesn't bother me so much as I tend to use vi for most text entry anyway and I'm used to hitting 0$ to flip. May be more of a problem for other people.

  3. Rubbish on Europe To Import Sahara Solar Power Within 5 Years · · Score: 1, Interesting

    If just 1% of the Sahara Desert were covered in concentrating solar panels it would create enough energy to power the entire world. That's a powerful number...

    That completely misrepresents the problem. If you cover 100% of the Sahara Desert with solar panels it still won't provide all of the power that the world needs, because some of that power is needed during night in that timezone.

  4. Re:If they're trying to keep it secret on Apple Quietly Goes After Mac Trojan With Update · · Score: 1

    You mean like breaking the nvidia graphics driver and ruining performance in any OpenGL application ....

    Oh no wait - that is the 10.6.4 update that they've just released. A serious QA fuckup that has resulted in me (like many other gamers) spending an afternoon rolling back my system. Of course I can't just downgrade the driver because Apple know best and don't allow downgrades from point releases.

    Of course the windows vendors have lots of different hardware configurations to deal with. Apple make the bloody hardware that they've just screwed up. Is that what they're supposed to do?

  5. Re:Does it have a monitor and full-size keyboard? on Flight of the Desktops · · Score: 1

    Have you tried the macbook keyboard?

    The Fn key is in the bottom left where ctrl usually is, so it's very easy to Fn+arrow for the navigation keys. As Ctrl is next to Fn it's easy to hit with one finger, or with a finger and a thumb.

    They keys also have a decent travel and a nice snappy/clicky feel that makes it a joy to type on. I've hated every desktop keyboard that I've come across since I started using one.

    Your post is the closest in the discussion to how to make money out of the list. The only problem is that you didn't think big enough. So the problem is that you can only sell each list once, and the stinky ones are hard to shift.

    Rather than sell the lists you want to securitise them. Bundle the lists up into tranches and sell rights to the loot in each tranche. By using clever financial magic we can make the bad stink from the oldest accounts go away and sell each account many times over.

    Absolutely nothing can possibly go wrong. We just just need to get Goldman-Sachs in on this and we are made...

    To solve your problem go and sign up for a free dyndns.org account. Very useful.

    When the infringement notice is generated I'd assume that there is a timestamp on it. Even if the ISP switches your IP they will keep a record of which customer that IP was assigned to at each time, so no trouble for them to map it backwards.

  11. Re:Dangerous on Scientists Propose Guaranteed Hypervisor Security · · Score: 1

    I've started using a similar technique myself. Although a windows partition on Bootcamp isn't really a virtual machine it assumes that attacking the Mac partition (which isn't mounted by the windows partition) is a small enough target that malware won't hit it.

    The checkpointing / rollback is handled by Winclone that just nukes the relevant partition and updates it to which-ever checkpoint was selected. It seems to work quite well and I haven't had any problems yet when installing questionable software and needing to go back to a clean machine.

    BTW, I love the sig. Don Knuth is something of a minor deity here (usually as revealed through the prophet Robert Sedgewick {grin}) as I've used his algorithms and data structures, and especially proofs of correctness and suitability to problem domains, in my work over the decades.

    Thanks but the credit is not mine sadly. Somebody used the quote in an argument over PHP a couple of months ago so I stole it as a quote :)

  12. Re:Dangerous on Scientists Propose Guaranteed Hypervisor Security · · Score: 2, Informative

    It's an interesting technique, but it is not a guarantee.

    The summary doesn't mention the number of assumptions that the researchers make:
    + A working TPM module
    + An adversary limited to memory corruption
    + No unknown faults in the underlying system that can be exploited.

    Also the second technique (restricter pointer indexing) relies on performing a static analysis of the target hypervisor and rewriting it into a suitable form. This is not guaranteed to terminate, let alone guaranteed to work, although it does on the small number of test-cases that they considered.

    Seems like quite an interesting paper, standard amount of overselling for American academic work (where every paper solves the world) and a shame that the reviewers didn't tone down the claims a touch.

    For which she provided no proof, and which were only mentioned in passing at the end of the complaint letter as an attempt to bolster her case. It also notes that the external examiners decided that the email exchanges between them that followed cast doubt on these allegation and did not uphold them.

  16. Re:Hameroff/Penrose model of quantum consciousness on Quantum Entanglement and Photosynthesis · · Score: 1

    So what you're saying is that when we try to implement A with B it doesn't work, therefore X is a necessary precondition of B? I'm afraid that logic (and science) don't work that way. Saying that because the things that we have tried have not worked is a reason to invoke X as the magic necessary ingredient is equally true for all X. And I don't think that a celestial teapot is the magic ingredient to AI, do you?

    Although pattern recognition is hard that does not mean that it is impossible with classical tools. It just means that we have not done it yet. And what do you mean by "linear computation model"? The word linear has many technical meanings, but none of them make your statement true.

    Not all parallel or asynchronous models require quantum magic. Hence the fact that our brain operates asynchronously in parallel does not imply that quantum magic is necessary.

    So they get over the minor inconvenience of their proposal not being possible. Now all that they need to do is jump the hurdle of it being completely unnecessary. There is no compelling reason why quantum phenomena are needed to describe conscienceness. Without a compelling reason then their theory has no use.

    Perhaps it would have helped if the press release had called it a digital watermark instead of a signature. One is supposed to be resilient to changes and to allow the author to claim that they created the original material. The other should break under any changes and is used to attest that the material is unmodified.

    When a company uses the wrong name for their product, some confusion is understandable.

    You could not be more wrong and I would be impressed if you could point to a single person with that belief. Much more common is a generation of people who don't believe in following an arbitary set of rules to preserve artificial scarcity. There really is nothing morally wrong with copying, it is not stealing and our laws are simply wrong.

    I choose to buy games simply because we don't have another renumeration method for game devs. If they are stupid enough to stick annoying DRM on there then I'll take the non-damaged version.
