6/19    Here is another question for all you knowledgable crypto people.
        How bad is the ability of a PC to generate random numbers for
        cryptography?  Is this at all a limiting factor in PC based
        encryption?  If someone were to build a little box that made
        random numbers based on a physical process that was provably
        uncorrelated, would that interest people?
        \_ PC's running reasonable OS'es generate good random numbers. -tom
        \_ Depending on the sources of entropy used, a ordinary PC
           can generate sufficiently random numbers for use with
           cryptography. Look at how ssh does it for more info.
        \_ P3s can generate random numbers based on thermal noise, right?
           \_ I don't know.  There IS a thermal diode on it, but I'm not
              sure of the response time.  Actually, that might be an
              interesting little problem/implementation to do, since a
              lot of devices have thermal diodes these days, for over
              temperature protection.  -nweaver

6/6     Wow, NSA rocks. Who would have thought they had access to major
        data exchangers? I have much more respect for government workers,
        crypto experts, mathematicans now than ever.

2/23    Has anyone read Anathem yet? How good (or bad) is it in comparison
        to Cryptonomicon?
        \_ Depends: what did you like/dislike about Cryptonomicon?
           \_ I started to dislike the overlapping WW2 and present day stories
              by the 1/2 half of the book.  And it seemed like a lot of the
              technical details were thrown in to prove how smart Stephenson

8/22    In Windoze XP, how can I make my service start automatically when it
        boots up in Safe Mode?  I searched MSDN site and didn't see anything.
        Thanks.
        \_ I don't know how to do that in Windoze XP but it isn't that hard in
           Windows XP.
           \_ And that would be how?  Thx.
