9/16    I got a used (free) computer, but I've realized that it locks up.
        I've swapped out the RAM, Mobo, power supply and disk. It still
        crashes.  (isn't really free, huh). The last time it was a seg
        fault in the /etc/init.d/umountfs while shutting down. The errors
        seems to be random, but possibly occur slightly more in the AM
        wee-hours. So the last thing to swap out is the CPU.  It's an
        Athlon ~1GHz. Are these symptoms typical for a bad CPU?
        \_ Someone probably tried an overclock and failed.  Get what you pay
           for.  Sounds like you bought a new computer in pieces and wasted
           a lot of time.
        \_ I used to think all memory are the same. As long as you get the
           right one with the right cycle (e.g. 2700/3200/etc) then it will
           work. WRONG. I bought my GigaByte motherboard with a generic
           RAM and nothing worked. Tried everything. Changed CPU, changed
           grafx card, even changed MB and nothing worked. Went back to
           Frys, and had them try out the IDENTICAL RAM but this time using
           Kingston and other more expensive RAM, and voila, it worked.
           Did some research on the WEB and found out that 1) some MBs are
           very RAM sensitive and 2) despite what I experienced in the past
           10 years, NOT ALL RAM ARE THE SAME!!!!
           \_ His mb is older.  That's not as big a deal on the pc100 or what
              ever is in there.  His cpu is an over-overclock victim.
              \_ The original mobo is a Spacewalker AK12 wit PC133 ram, but
                 for the replacement, I bought an Asus A7V8X-X and some
                 high-quality PC2700 DDR SDRAM from central computer. -op

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

2/5     How is Firefox on version 10, while I still have 3.6 installed.
        I wait for the X.1 versions and they never come out.
        \_ I'm also on 3.6.26.  It claims that versions 4 - 10 are all faster
           than 3.6.x, but do they use more memory?  Thx.
           \_ Newer Firefox versions use less memory too:

6/5     In an effort to stabilize our services, we'll be rebuilding parts of
        the CSUA infrastructure over the course of this summer.  To give us
        some wiggle room, I've temporarily decreased soda's allocated RAM from
        8GB to 2GB.  If you need to run something that requires large amounts
        of memory, please send mail to root@csua.org and we'll try to
        accommodate your request.  --jordan

3/19    When you're explaining the stack to people do you draw it with the
        highest addresses at the top or at the bottom?
        \_ When I explain any memory layout including stacks, I draw with the
           highest addresses at the bottom.  But I've seen people doing the
           other way.  -- yuen

7/25    What's up with that moving bit pattern that Win7 displays when it
        boots up?  (It's the one that's like in the Apple II days when you
        use the graphics memory for code or data while it's still in HGR
        mode.)  Is there a way to disable that?  It slows things down a lot
        every time I reboot my Win7 VM on my office machine if I RDP to the
        machine via DSL.  Thanks in advance.

7/20    For those who care btw, it looks like eclipse is now A Standard Tool
        at UCB ugrad cs, probably replaced emacs.  Furthermore, people get
        angry at seeing Makefiles, (since eclispe takes care of that).  I
        guess it's just a sign of the times.
        \_ The more people at my work use eclipse the less the code is
           managable in emacs.  I'm not sure which application's fault
