10/17   I'm on a linux box, logged into another linux box on the same
        network and want to run x-windows on the remote box in a way that
        will display on my local terminal.  Is it possible?  How?
        \_ xhost or ssh's X11 display forwarding.  And sign your name.  -John
           \_ As in
              on local computer:
              xhost + remotecomputer
              on remote computer:
              setenv DISPLAY localcomputer:0   (in tcsh) or
              DISPLAY=localcomputer:0; export DISPLAY  (in (ba)sh)
              or easier yet, just ssh -C and everything will fix itself.
              \_ <snip rant about xhost + being insecure; xhost + a single
                  host has no serious consequences whatsoever>
                        \-clearly a sloda new comer :-) --psb
                \_ uh, it does if anyone else can log on to that computer.
                   \_ well, alright, within bounds of common sense, that is
                                \- i havent looked at the x internals in a
                                while but as of 3-4 years ago there was a
                                sneaky way once you did a xhost + to not let
                                a later xhost - work ... this really isnt a
                                good idea. it's not a matter common sense but
                                ignorance of what is under the hood. --psb
                                \_ There's also the fun "xhost -" which will
                                   prevent further "xhost +" commands from
                                   working since you've also killed localhost.
                                   Please restart X or reboot to fix.  Depending
                                   on X config, logging out and in again won't
                                   necessarily 'fix' the xhost settings.
                        \_ Idiot.  DNS can be spoofed, moron. I *know* you
                           don't work at my company. You'd never have gotten
                           hired babbling stupidities like "'xhost + host' has
                           no serious consequences whatsoever".  You're a
                           complete and utter fool.  Do they still not teach
                           any sort of computer security class at Cal?
                                \_ Grad level only unfortunately.
                           \_ Only people who hang out with CSUA geeks ever
                              learn about this stuff by the time they graduate.
                              BS/BA != clue.
                                \_ The "it's harmless" person isn't spending
                                   enough time with CSUA geeks then.  It
                                   doubly pisses me off that this ignorant
                                   jerk went so far as to actually delete my
                                   completely true and correct comments about
                                   not doing this and was stupid enough to
                                   refer to said comments as merely ranting.
                                   I'm certain this fool has graduated yet,
                                   I'm certain this fool hasn't graduated yet,
                                   so maybe there's still some slim hope, but
                                   I doubt it.

4/22    In the old days there was VGA and life was fine. DVI was quite
        tolerable. Then Mac f***ed it up and came up with mini-DVI
        and I had to get new connectors. Then DVI to VGA to my
        older monitor. Now I have to deal with a bunch more shit
        like displayport, mini-displayport, HDMI, and mini-HDMI.

2/5     I like Adobe Flash. When written correctly, it scales along
        with your browser size. It looks consistent on every single
        browser. It is predictable. On the other hand, I'm not a big
        fan of CSS/HTML, which for the most part, look wildly different
        between browsers, and don't even work consistently or
        correctly at times. So why do so many people (like Steve Jobs)

7/4     I'm accessing soda by typing ssh -X jhcooper@csua.berkeley.edu
        at a Linux prompt.  At the soda prompt, I can type "xmessage hello &",
        and I get a nice little greeting from myself popping up on my display.
        But if I type xterm &, the process runs ok, but nothing appears on

11/20   Are there tools that can justify a chunk of plain ASCII text by
        replacing words with words of similar meaning and inserting/removing
        commas into the text?  I received a 40-line plain text mail where
        all the lines are justified on left and right.  Every word and comma
        is followed by only one space, and every period is followed by two
        spaces.  The guy is my kid's karate instructor which I don't think is

10/24  What's an easy way to see if say column 3 of a file matches a list of
       expressions in a file? Basically I want to combine "grep -f <file>"
       to store the patterns and awk's $3 ~ /(AAA|BBB|CCC)/ ... I realize
       I can do this with "egrep -f " and use regexp instead of strings, but
       was wondering if there was some magic way to do this.
