8/18    I want to build a CPU load monitor a la the BeBox. Basically its
        a string of leds that light up depending on the current load. Any
        ideas where I should start looking for information on building this
        thing?
        \_ What platform?  If Unix, there are already tons of similar
           utilities -- search freshmeat for "load monitor", select
           the one you like most or change the source if you want
           your own eye candy.
           \_ i'm looking for something that controls actual leds
              via a serial port or something.
              via a serial port or something. Its for my Linux machine.
              \_ http://metalab.unc.edu/pub/Linux/system/status/led-stat.txt
                 and other files in the same directory
                 \_ thanks, this was exactly what I wanted.

8/18    Data problem: I'm working in MATLAB v.5 (in UNIX) I need to transfer
        a matrix that I computed in MATLAB into EXCEL. How do I do
        that? I tried saving using "matrix_name -ASCII", then I ftp
        to the desktop and tried to have excel read and I get gibberish.
        Please e-mail or post. This bugging the shit out of me and
        I need to solve this problem soon. -fab
        PS I tried using Stat transfer and it also give gibberish.
            \_ Don't use MATLAB!  Use Mathcad or Mathematica with
               the matrices graphically written out for you!
          \_ You are right,MATLAB blows. But I'm stuck with data
             I have in MATLAB. I also don't have access to M/matica
             right now. -fab, who is lame and knows it
        \_ help dlmwrite -brg

        \_ I'm pretty sure there's a way to write matrices to an
           ASCII file but my MATLAB CD is in the office.
        \_ Take a look at ~emin/save_matrix.m.  This is a simple
           function to save a matrix as tab delimited data using fprintf.
           Since it's a function you can easily modify it to do comma
           separated format or whatever you want.  -emin

8/19    When I run ps, I see this process:

        STAT      TIME  COMMAND
                --snip--
        IEs+   0:00.00  (ntcsh)

        It is from a connection that timed out, so I'd like to kill it.
        However, when I run kill -9 <pid>, it doesn't work.  Any ideas?
        \_ Look for the pid of the controlling tty and send it a HUP.
           \_ ntcsh is the login shell of that particular session though.  Or
              is the controlling tty something else?  If it is, how do I find
              it?

8/17    By default, does JDK1.2.2 run w/ JIT, or there is a flag to give?
        \_-Djava.compiler=shujit        this is an example.
        \_ No jit by default on most platforms. Notable exception WinBlows.
                \_ BUZZ wrong.  Solaris jdk1.2.2 and up runs with a JIT
                   by default.  make the http://java.compiler env var = NONE if
                   you want to turn it off for debuggin purposes.  And JDK 1.3
                   uses "HotSpot" which is a faster kind of JIT.
                \_ Most of the command line options are documented. HotSpot
                is available with 1.2.* JDKs also. The 1.3 one is HotSpot 2
                is available with 1.2.* JDKs also. the 1.3 one is HotSpot 2
                out on Windoze, beta on Solaris. I find HS 2 beta to be much
                better than the "stable" HS 1. HS is not a JIT and is not
                necesserily faster than a JIT. I'd say if you don't know
                exactly what you are doing or don't spend most of your time
                in Sun's libraries it will kill your performance. -muchandr

8/19    How do i disable the front power button on an Ultra 5?
        But I still want the green power light to work.
        \_ Open it up, and pull the red wire.
