    I haven't downloaded that file, but doesn't MS always digitally sign their updates? If so, you could right-click on the EXE, select Properties, then go to the "Digital Signatures" tab to check the signature.

    Prions are proteins. Proteins are long chains of amino acids. Those aren't going to fit through the membrane either.

    Viruses are much much bigger than a urea molecule. Even one of the bases in the RNA of a virus is bigger than a urea molecule. Urea is CON2H4. The smallest RNA base, uracil, is C4N2O2H4.

  10. Re:IBM already ships 400GB SATA disks on Seagate Rolls Out 400 GB SATA Drives · · Score: 2, Informative
    And why would Seagate only have 3 platters? Each disk has 2 sides, so unless the system is crippled (i.e. they use rejects with only 1 good side) the platters should be a multiple of 2.

    No, the number of platters is however many platters they decide to put in the drive. The number of heads is the number of platters * 2. Two heads per platter--one for the top, and one for the bottom.

    Are there maps available through other agencies (national or international)?

    What's the reasoning behind the national or international restriction? The local government handles building streets, and they're the ones who provide the maps. For example, the Texas Department of Transportation makes their maps available here.

  14. Re:they need updated docs for todays ram amounts on Is Swap Necessary? · · Score: 1
    That's a feature/design decision. Windows NT writes pages that haven't been accessed recently to swap while the system is idle, so that when the system is low on RAM, it doesn't have to spend time paging stuff out. The pages are already in the swapfile and it can reuse that RAM immediately.

    Seems to work fine for me--I don't notice any slowdowns until my working set size exceeds RAM size. I dunno; if your app uses about 400MB, leaving 112MB for Win2K to use seems a bit tight to me.

  20. Re:Open Source MMO on Sony Slow To Reveal Mac EverQuest Code Freeze? · · Score: 1
    Netrek isn't unplayable. The client is open-source, but the servers can be set (and normally are) to only accept connections from "blessed" binary clients. Each official client has an RSA keypair. The server sends a random challenge to the client, the client signs it and sends it back to the server. If the signature verifies, and the public key is on the approved list of keys, the server accepts the connection.

    The weak point is that it's possible to extract the private key out of a blessed client and use it to sign challenges in a hacked client, but the impact is mitigated since it's very easy to remove the compromised key from the list of approved keys.

    Anyways, certainly not 100% protection, but it stops casual cheating, while still being open source.

  23. Re:It just works? on How To Play Your iTunes Music On Other Systems · · Score: 3, Insightful
    That's pretty interesting... Your earlier message says Apple added a flag to execve(), but Darwin's execve() looks standard to me:
    int execve(const char *path, char *const argv[], char *const envp[]);

    Having execve() do the protection wouldn't work anyways, seeing that gdb wouldn't call execve() with that flag set. I ktraced iTunes, and it's just calling ptrace(PT_DENY_ATTACH, ...) on itself, rather than having its parent do it. You could probably run iTunes under a debugger and set a breakpoint on ptrace() and skip over the offending call.

    On the other hand, while recompiling Darwin may not be "something a user would be able to do" (I've never tried), I'm sure someone who is knowledgable enough to reverse engineer iTunes' key generation scheme is also capable of compiling their kernel.

  24. Re:Not as English as you think.... on The Logic Behind Metric Paper Sizes · · Score: 1
    The IUPAC seems to think that "aluminum" is just fine. As is "cesium."
    Finally, for American readers, it is noted that alternate English language spellings for the names of aluminum and cesium are used in the USA and do not constitute erroneous spellings. -- linky

    P.S. Al was named "aluminum" back around 1807 by Sir Humphry Davy. He later decided to go with "aluminium" to match the "-ium" suffix of other elements. I have no idea whether "aluminum" is a marketing tradename or not, but it's definitely not the origin of the "-um" spelling.
