    As soon as your grandpa connects to the internet, the AV can just poll any time server on the net, including inofficial ones set up by the AV vendor, using different ports and even possibly a different protocol. Indeed, the timing information could even be implicitly included in the communication with the AV update server. Since there's an external server involved, the root kit cannot control all aspects of it unless the update server itself is compromized (if the update server uses public key kryptography to sign its messages, the root kit cannot simply modify the data stream).

    You're honestly giving Internet time servers too much credit if you think of depending for nanosecond resolution on them.

    The problem is, that if the VM writer tries to take every possible method to make the execution time similar (e.g. make privileged instructions run as fast as non-privileged instructions), it has to slow the faster ones down. Suddenly, even your grandpa will notice something is wrong. The most insane method would be a VM based on a full-blown, cycle-accurate simulator, but that will be horribly slow.

    Two things:

    1. You assume the clock isn't manipulated, hence fast commands should be slowed down to match virtualized instructions. Instead the direct instructions may be left running, and the virtualized to skew the clock subtly enough to be undetectable to the naked eye, and match well with the hardware performance to a detector running within.

    2. We're soon about to get plenty of cores on desktop machines, where most of the tasks are serial. If a VM would make use of the extra cores to simulate a single core in around 50-60% its native speed, it may prove undetectable to granda who just browses the net and uses Excel.

  8. I read the paper on VM-Based Rootkits Proved Easily Detectable · · Score: 5, Interesting

    I'm still convinced that it's possible to make a VM that appaears to software running within as real hardware.

    The paper, however, takes a practical approach, examining how some industry standard VM-s operate, such as VMWare and Virtual PC.

    Those VM-s take plenty of shortcuts to improve performance, and don't virtualize some instructions, rather remap them, or "shift rings" of execution etc. as much as possible so to take advantage of the hardware while remaining sandboxed. They don't virtualize the clock as well, so you could time the performance.

    A rootkit isn't competing with other rootkits based on performance, it does so based on how undetectable it is. It's arguably a different problem. I think we're yet to witness what a full blown VM made to be a rootkit will act like, and whether it'll be detectable.

    It's just that Sony isn't exactly the Rolex of TV-s (anymore...?), so buying a tiny OLED TV isn't going to impress much anyone. Buying a big LCD TV mounted on the wall would do better.

    There is no point. You need to see Microsoft thinks in multiple steps, and this is just step 1.

    Step 1 is about rolling out a beta of this software, and allow the public to test it, give feedback, and their devs to improve on that.

    The fact they offer it only to existing customers means there's no chance that this may hurt their Office sales. And it also lets the world know that Microsoft is "aware" of competing web products, such as Google's.

    Should things get rough (Step 2), Microsoft already will have a mature web product in their hands, it will have people familiar with working with this product, and have the option of changing how to offer it, including separately for an yearly fee, as Google does.

  20. The big picture on Groklaw Guts the Novell/Microsoft Deal · · Score: 4, Insightful

    Microsoft has some emerging issues it has to deal with:

    - the threat of a free OS commoditizing what they worked so hard to keep unique in Windows
    - the emerging of accepted open standards that turn Microsoft's proprietary alternatives against themselves and wall them from the rest of the world
    - the emerging of plenty of companies ready to deliver free OS components and support to Microsoft's corporate customers (which will directly affect Microsoft's bottom line and the industry trends in adoption of Windows)

    Microsoft's business strategists have done a careful and detailed analysis of their situation and arrived at the infamous "patent deals". They have drawn the decision chart and figured, there's no way for them to lose, no matter how the market or their competition moves.

    Possible outcomes & side effects:

    - The patent threats split Linux community and cause unrest in corporate clients who consider adopting Linux for their servers or even desktops.
    - Novell and the other distros in the patent deal are rejected by the community and Microsoft eliminates one of its more dangerous competitors should Linux' adoption really take off. -OR-
    - Red Hat and the other distros OUT of the patent deal get destabilized and abandoned by the corporate clients and Microsoft gets to "coown" the Linux code together with Novell by means of the patent implementations all over the code. They can't just buy Novell now since it'll destabilize their Windows brand, and cause antritrust lawsuits. But should Windows go down next 5-10-15 years, you can be sure Microsoft will be talking to merge with Novell and offer their Linux distro with all the windows IP in it.

    In essense Microsoft either gets to split the OSS movement, eliminate some of their stronger competirors, and improve the Windows brand and adoption, or gets a second route to quickly enter the market with Linux OS should Windows go horribly down, by utilizing all their Windows IP inside the Linux system.

    What about standards:

    - Where Microsoft has their own standard opposed to an open competing standard, they try to promote it to a full standard (OOXML, Exchange server integration with SUSE, ActiveDirectory integration with SUSE etc., XPS)
    - Where Microsoft doesn't have their own standard, they adopt the publicly accepted standard, and extend it in attempt to create added-value dialect (RSS with own extensions in IE7, .NET and Silverlight competing with Flash and AJAX web apps, XML markup base for Microsoft's new standards such as OOXML and XPS, IIS7 configuration XML files etc.)

    So Novell's deal helps Microsoft make better penetration of Microsoft standards and technologies as something that comes standard with Linux. We're talking about Mono, Moonlight, Exchange integration, Samba integration and all those technologies which might have alternatives outside the Microsoft world.

    This is marked to the public outside as interoperability effort. It sure is improving interoperability, but at the cost of putting more and more MS IP in Linux's distributions.

    So was Novell wrong to sign the deal? If they had the pure intention to move the OSS community and help Linux as a whole, it was wrong. But as a company that competes against *OTHER* Linux distro companies, it was half right.

    Right now if you see above all the outcomes from this deal (which are all good for Microsoft) there's 50/50 about who will survive (the non-patent deal Linux companies, or the patent deal Linux companies). Novell and RedHat are on the opposite sides of a gamble that'll play out in the next years.

    While they're the gamble players, Microsoft is the casino. Never mind who wins, the casino always wins. Good job, MS :)

Consider: OLED has shorter pixel life and wastes less power than LCD+light. Where is this useful? Laptops (limited energy and no constant use). Where is it harmful? TV-s (constant use and unlimited AC power).
    3. The design is made to impress, not be practical. Notice they put the tuner down in an ugly box to show off the very thin OLED display (no backlight). Notice the off-center hinge, designed to stress how light the screen is (puts unneeded stress, however small, on the materials).

    Bottom line is, of course, great that someone is pushing OLED for something bigger than a camera preview screen. But it's NOT mass produced product. They make just few units, to make the news.

    It's a product straight from the PR department. I suspect Sony Rolly will have similar fate.
