Code and Unix tips

All code here is licensed under the GPL, if not noted otherwise. - a small utility to display a new background every now and then - can run a program and/or pick a random weighted file to display. - used by above to randomly select a picture or program.
.update-backgroundrc - rc file to put in your home directory for above programs - make sure it is acutally named .update-backgroundrc
colorgrep - I got used to things like colordiff (and hooking that into cvs to get cvscolordiff), and I decided that grep needed a color flag too. It can highlight lines that match, highlight the actual match within each line that matched, or just highlight only each match within each line.
weather - a small utility that displays the weather in an australian city in a small gnuplot window at the bottom of your screen. Change the internal URL to point to the Bureau of Meteorology webpage for your city, and it displays the last 72 hours, as well as keeping a permanent history for later perusal - see the yearly trends! (screenshot here)
progressbar - A progressbar that accepts input from stdin, and outputs either to a Gtk based app, if Gtk-perl is available. Gtk-perl and Timer::Hires are both recommended, but this will still function without them). Needs but only because it defines max/min. Just define these yourself, and you are happy (or place in @INC).
mycat - A perl program that can transparently cat a text/gzip/bzip2 file. It can also exit a specific exit code if it is text, to tell caller that the file is a text file and can be open directly (so caller can then make use of seek, and doesn't need to read through an external program slowing things down). Needs for the actual zcat routine. Place in @INC, and you are away.
mailoops - A perl program that mails any oops or bugs, that are sent to /var/log/syslog. Put in /usr/local/bin, and then install init.d/mailoops in /etc/init.d as appropriate (and set up the relevant links in /etc/rc*.d), to start mailoops automatically at boot. Newer kernels automatically decode the oops traces, so you don't need a separate ksymoops utility anymore. This program runs through the current log, so you will get any oopses that happened any number of boots ago, as long as it is in the current log - just in case the oops caused a crash and reboot. It automatically includes a minute of context on either side of the error. It could be trivially modified to look for other strings that just oops or bug, so you could detect conditions appropriate to your system - only tested on debian though (other systems probably use /var/log/messages instead of /var/log/syslog - just change the relevant line) - a small utility used to generate x-faces for Unix news and mail clients.
xemacs - xemacs dot files and configuration files that may or may not include usefull things.
nfs-bind.txt - Using NFS and bind mounts to their full advantage, so you can apt-get upgrade on a very small RAM machine.
Fortran: Bits and pieces of fortran routine I find useless^H^H^H^Hful.
