10/29   ssh cipher: blowfish or 3des... and why?
        \_ 3des is more processor intensive.  Blowfish is younger, but
           theoretically superior because of some math that I don't
           understand.
        \_ Blowfish. Its faster than 3des and can support a longer key
           length (448 bits vs 168 bits). There are no known exploitable
           weaknesses in full Blowfish (Blowfish with reduced rounds is
           exploitable).
           \_ The key length difference between two _different_ algorithms
              is irrelevant unless you have a thorough knowledge of the
              actual keyspace _AND_ decryption complexity of each, which
              we don't. -alexf
        \_ Blowfish.  It's faster and as (if not more secure) as far as
           anyone knows.  If you're securing stuff against a hostile gvt,
           perhaps you should stick with something safer and slower, otherwise
           don't kid yourself, blowfish is fine.
           \_ "Make no mistake! We will crack it for surveillance purposes!"
               \_ muahahahahh! your puny crypto will fall before our mighty
                  quantum computer!  ...just give us another few decades.
                                           -a physicist
                  \_ wouldn't this lead to an unbreakable cipher as well?
                     or is this only if you have a quantum comp also?
                     \_ Comrade, I am having zee unbreakable cipher. It
                        iz called ze one-time-pad. We have been uzink it
                        for years you unwashed american pig dog.

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.

2/24    Go Programming Language.  Anyone here use it?  It kind of
        reminds me of java-meets python, and well, that is fitting given it's
        a GOOG product.  What is so special about it?
        \_ as I understand it, it's a suitable OOP-y systems language with more
           structure than C, less complexity than C++, and less overhead than
           Java/Python.

3/7     My sister is graduating soon with a decree in information management.
        She was orignally CS, but couldn't cut the math, so her GPA sucks.
        However, she has had a couple of internships and did fine.  She did
        desktop support at RockYou and is currently doing web programming
        at UC Santa Cruz, but they can't keep her on after graduation.
        Anyone got any jobs?  She wanted to be a network admin, but right now
