  1. Re:Remove it and ship it off on Warrantless GPS Tracking Is Legal, Says WI Court · · Score: 1

    You could possiblly detect a GPS receiver by picking up the local oscilator frequency (or frequencies in if it's a double conversion receiver) depending on how close you are and how leaky the radio circuitry is.

    You could also possiblly detect the device "phoning home" to report the tracking information.

    One problem could be depending on how often they want samples and how much battery life they require the device may spend most of it's time sleeping and hence almost completely radio silent.

    There's plenty of netbooks that were sold with huge bezels around the screen. Whilst I don't want the netbooks to be physically bigger, I'm more than happy to pay for a screen that goes to the edges of whatever sized machine I've bought.
    BTW such machines do exist already, for example the HP mini 2140 crams a 10 inch screen, a standard 2.5 inch drive and even an expresscard slot into a box about the same size as an EEE 900. I just wish thier UK website offered the "HD" screen option.

  3. Re:My theory why: multiprocessors on Oracle Won't Abandon SPARC, Says Ellison · · Score: 1

    Not easilly they can't. Standard IC technology basically relies on etching transistors into the surface of a damn near perfect single crystal silicon wafer. Wiring is then built up over the top of this layer of transistors

    So you can't easilly build one layer of transistors on top of another. I guess you could use technology similar to that used for SOI but I strongly suspect it would be very expensive and bring little gain.

    You can stack whole chips on top of each other, but afaict it's only done when space is really tight and typically on much lower power stuff than PCs use (there are some arm chips for example where you can put the ram and flash directly on top of the CPU). Remember heat is a big issue with PC CPUs.

    How exactly does one put a price on moon rocks?
    With great difficulty since afaict none has ever been sold openly so you can't really put a market value on it.

    If you price it at the cost of getting more the value would be very high indeed. According to wikipedia Apollo cost "between $20 and $25.4 billion in 1969 dollars (or approximately $135 billion in 2005 dollars).". and returned "381.7 kg (841.5 lb) of rocks and other material from the Moon" If we use the 2005 dollars (which should be reasonablly close to 2009 dollars) that works out to $354 million dollers a kilo!

    Of course apollo did other stuff and plain sample return missions would be cheaper but still returning stuff from the moon is not cheap.

    Actually, I'd be interested in knowing how this works (assuming it's true)

    Actually finding out how wine does 16 bit code is trickier. I've found out from the documentation that it involves something called "winevdm.exe.so" but i dunno how that binary does it. I guess it would be possible to RTFS but I don't care enough to do that.

    To my knowledge 16-bit instructions aren't available in 64-bit mode, so it can't just be running it natively
    You can't do 16 bit real mode code under a 64 bit kernel. I'm not sure what the situation is with 16 bit protected mode code (wikipedia claims it's possible but doesn't provide a citation for that claim)

  10. Re:Apple is a stealth software company on Oracle Won't Abandon SPARC, Says Ellison · · Score: 2, Insightful

    Afaict the hard part in emulation is doing it fast.

    Simple interpretive emulation is pretty easy and if you only want to run apps from another CPU (rather than a whole OS) you don't need to emulate much in the way of hardware since you only have to emulate the userland environment.

    If you want good performance from your emulation you have to use "dynamic recompilation", basically converting the machine code from one CPU to another in blocks and then emulating it.

    x86 (remember the original intel macs were NOT x64, that came later) is widely known as a register starved architecture. PPC OTOH has plenty of registers.

    I would imagine translation of code from a register poor architecture to run on a register rich architecture would be much simpler than translation of code from a register rich architecture to run on a register poor architecture.

  13. Re:First MD5 and now this on Preparing To Migrate Off of SHA-1 In OpenPGP · · Score: 1

    Another big issue with a lot of current hash functions (at least MD5 and I think SHA1 too) is that thier block based nature means that if you can reasonablly generate two collisions of "random garbage" you can reasonablly generate two files with a prefix you choose before generating the collisions, followed by the two sets of "random garbage" followed by a suffix you choose AFTER generating the collisions.

    Combine that with a carefully selected file format (IIRC it can be done with pdf) and you can make two files that have the same hash with different meaningfull content visible and no visible random garbage.

    This makes "random garbage collision" attacks much worse than they would appear at first sight.

    Running the repair tool off your install CD should fix this, or you can do a reinstall with "leave filesystem alone" option.
    Unfortunately a significant proportion of OEMs don't provide proper install CDs anymore :(. Afaict that started sometime arround the late win98/early winME era (I never bought a machine that came with 2K big brand OEM so I can't comment on what happened there).

    In the 98/ME/2K days this wasn't such a big deal since you could just borrow a CD from someone who had a proper copy. However microsofts actions with and since the release of XP have made it much more awkward to get arround this by just borrowing a CD. Big brand OEM copies are bios locked. system builder and retail copies require activation and if you use them with a big brand OEM key you are going to have to ring MS and beg for activation. Volume license copies of XP don't have this shit but using a generated key is likely to trip up WGA and using a borrowed key on any machine you don't control puts the company it was borrowed from at risk of ending up on the WGA shitlist. With vista the no-activation-requied VLK copies have gone completely.
