  1. Swappable drives on Some Windows Apps Make GRUB 2 Unbootable · · Score: 1

    I gave up on multi-boot installations a number of years, ago. I've had my last couple of PCs configured with swappable drive bays. When I want to boot a different OS, I just stick in a different drive.

    Dropping 'h's is a significant characteristic of the Cockney accent.

    And to a Yank, of course, the only two British accents are BBC and Cockney.

    (I saw a production of The Pirates of Penzance, once, where the constabulary used Cockney. The idea that the lower classes from Devonshire and Cornwall might have different accents than those from London's East End never seems to have occurred to them. But then, most Yanks think that the Beetles had Cockney accents. Gads!)

  3. Re:The cipher on A 1941 Paper-and-Pencil Cipher · · Score: 1

    It's beyond the realm of possibility that any German intelligence agency would have been using single transposition in 1941.

    Or not!

    I was reading David Kahn's "The Reader of Gentlemen's Mail" - his biography of Herbert Yardley. In 1941, Yardley was working with the Canadian government, helping them set up a crypto bureau. Most of what they were cracking were messages to German spies working in South America - and yes, they really were using a simple transposition cipher, just like had been appearing in puzzle books for decades.

    I've posted it over there, I'll post it here.

    Read section 12-3 of FM 34-40-2:

    http://www.umich.edu/~umich/fm-34-40-2/ch12.pdf

    This technique of solving incomplete columnar transposition ciphers had been described in the open literature prior to 1941.

    It was described in Helen Gaines' "Elementary Cryptanalysis", published in 1939. Many of the techniques in Gaines' book originated in M.E. Ohaver's column "Solving Cipher Secrets", in "Flynn's Weekly Detective Fiction" magazine, which ran from 1924 to 1928. I'd not be at all surprised to find that this technique was described there.

    It's beyond the realm of possibility that any German intelligence agency would have been using single transposition in 1941. It's not at all impossible to believe that someone at the FBI, asked to create a worksheet for a Life photo-op that didn't reveal anything of substance, would choose to demonstrate the cryptanalysis of a cipher that was already widely-known among the well-informed amateurs. and hence wouldn't compromise any of the systems the Germans were actually using, or how effective they were at breaking them.

    It is possible that this was a partial setup, but in this case it was the question of a deception message that was about to be sent using encryption that was probably already blown at the time.

    Yep.

    The worksheet shows the cryptanalysis of a simple transposition cipher using a technique that was included in Helen Gaines' "Elementary Cryptanalysis", published in 1939.

    Whether it was ever a secure cipher I can't say. But by the late 30's, it was appearing in the advanced puzzle magazines.

  7. What if you "accept" only the refund part? on Toshiba and EULA · · Score: 1

    according to the US Uniform Commercial Code:

    1. You have the right to inspect the product before you accept it. - UCC 2-606(1)(a)

    2. If it is impractical for you to inspect a product before you take it home or to the office, then you have the right to inspect it there. -
    UCC 2-606(1)(b)

    3. If the product doesn't conform to the contract, you may:
    - reject the whole
    - accept the whole
    - accept any commercial unit or units and reject the rest. - UCC 2-601

    These shrink-wrap "licenses" are in direct conflict with your legal rights under the UCC, which is why the SPA is working so hard to revise the UCC. But until they do, they haven't a legal leg to stand on.

  8. So, MS just changes the EULA, right? Nope! on Australian Linux user gets Windows Refund · · Score: 1

    The EULA has nothing to do with it. You have the right, under US law, anyway, to return all or any part of a product for a refund if it doesn't perform as specified.

    And of course, no MS product ever has.
