12/18   Happy 25th birthday Perl, and FUCK YOU Larry Wall for fucking up
        the computer science formalism that sets back compilers development

12/23   In Python, why is it that '好'=='\xe5\xa5\xbd' but
        u'好'!='\xe5\xa5\xbd' ? I'm really baffled. What
        is the encoding of '\xe5\xa5\xbd'?
        \_ '好' means '\xe5\xa5\xbd', which is just a string of bytes; it has
           length 3.  Python doesn't know what encoding it's in.  u'好' means
           u'\u597d', which is a string of Unicode characters; it has length 1,

4/16    Whoa, I just heard that MIT discontinued 6.001 (classic scheme)
        to 6.01. In fact, 6.00, 6.01 and 6.02 all use Python. What the
        hell? What has the world become? It's a sad sad day. SICP forever!

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.

1/14    Why is NULL defined to be "0" in C++ instead of "((void *) 0)" like in
        C?  I have some overloaded functtions where one takes an integer
        parameter and the other a pointer parameter.  When I call it with
        "NULL", the compiler matches it with the integer version instead of
        the pointer version which is a problem.  Other funny effect is that
        sizeof(NULL) is different from sizeof(myPtr).  Thanks.

4/29    Why were C and Java designed to require "break;" statements for a
        "case" section to terminate rather than falling-through to the next
        section?  99% of the time poeple want a "case" section to terminate.
        In fact some compilers issue warning if there is no "break;" statement
        in a "case" section.  Why not just design the languages to have
        termination as the default behavior, and provide a "fallthru;"

        why is strlen (or any other libc fn) at the same address every time?
