Season's Greetings
To my Democrat friends:

Please accept (with no obligation, implied or implicit) best wishes for an environmentally conscious, socially responsible, low-stress, non-addictive, gender-neutral celebration of the winter solstice holiday,practiced within the most enjoyable traditions of the religious persuasion of your choice, or secular practices of your choice, with respect for the religious/secular persuasion and/or traditions of others, or their choice not to practice religious or secular traditions at all. We also wish you a fiscally successful, personally fulfilling and medically uncomplicated recognition of the onset of the generally accepted calendar year 2009, with due respect for the calendars of choice of other cultures whose contributions to society have helped make America great (This is not to imply that America is necessarily greater than any other country, nor that America is the only country in the Western Hemisphere), and without regard to the race, creed, color, age, physical ability, religious faith or sexual preference of the wishes. By accepting these greetings, you are accepting these terms. This greeting is subject to clarification or withdrawal. It is freely transferable with no alteration to the original greeting. It implies no promise by the wisher to actually implement any of the wishes for himself, herself, or others. This greeting is void where prohibited by law and is revocable at the sole discretion of the wisher. This wish is warranted to perform as expected within the usual application of good tidings for a period of one year or until the issuance of a subsequent holiday greeting, whichever comes first, and warranty is limited to replacement of this wish or issuance of a new wish at the sole discretion of the wisher.


To my Republican friends:

Merry Christmas and Happy New Year!

Alpha
Due to the power failure, there was the loss of several hours of work. Last night I installed FreeBSD 6.2-RELEASE on an old DEC AlphaStation 200 I have. I had started building a new, smaller kernel for it around 23:30 last night. It had not completed by the time of the power outage. I have restarted that build.
Any one reading this would reasonably ask, "Why are you not as confused/angry/annoyed with a compile that was not finished in 7 hours as you were about one that took 3 hours?"
The answer is simple. This AlphaStation is powered by a 100MHz DEC Alpha EV4 CPU and has 64MB of RAM. To the best of my knowledge, DEC made this machine around 1994 or 1995. I expected the build to take a long time; the machine is around a dozen years old.

chdir(2)
So today at work another developer many years my senior, with many more years experience than I, came to me with a Unixy problem.
"When I have a program, how can I have it so the current working directory for all processes it starts isn't the one that it started in?"
"chdir."
"No, I want so that if this process starts something like ls, when ls stats 'dot' I want 'dot' to be the directory that process wants it to be, not the directory that process was started from."
After about 15 minutes of me suggesting chdir while he said that's not what he wanted but then describing chdir, I finally wrote something along the lines of the following

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>

int
main (int argc, char *argv[])
{
  system("/bin/pwd");
  system("/bin/ls");
  chdir("/tmp");
  system("/bin/pwd");
  system("/bin/ls");
  chdir("/etc");
  system("/bin/pwd");
  system("/bin/ls");
  chdir("/");
  system("/bin/pwd");
  system("/bin/ls");
  return 0;
}

I compiled that, ran it, showed him the output. He said, "Yeah, that's what I want to do."
I showed him the code.
"chdir does that?"

Fun little alias
I use a console based RSS reader written in Ruby. It crashes often and will delete my list of feeds in the process. It also has a tendency to not fully exit, leaving a ruby process sitting in the background soaking up close to 100% CPU time. For such occasions, I've added the following alias to my .cshrc file.

alias killraggle kill -9 '`ps ax|grep raggle|grep -v grep|awk '\''{print $1;}'\''`'
