Conciseness

In programming, beautiful structures often emerge after you try trimming away duplication or redundancy.

base64 representation of current time

#!/bin/bash
time=$(date +%s%N)
s=$(for b in `bc<<<"obase=256;$time"`; do
j=000`bc<<<"obase=8;$b"`
j="\\${j: -3}"
echo -n $j
done)
eval "echo \$'$s'"|base64

A place

If we can partition our life into stages, will there be one that we can stand? Or, it's going to be an eternal struggle to reach the next? I need strength...

The Chase is On

There is no point in live where one should feel content with one's growth, in power and ability generally, in mind and control particularly. While contriving, expressing ideas and moving are just the beginnings, the rate will likely determine everything.

remove duplicate paths from $PATH in BASH

Here is one that I came up with:
PATH=`awk -F: '{for(i=1;i<=NF;i++){if(!($i in a)){a[$i];printf s$i;s=":"}}}'<<<$PATH`

torque, rsync, and selinux

Somehow, rsync dies quietly when run inside a qsub script if selinux is enabled (on a Fedora 7 system). I can by-pass this by changing the security context inside the script. However, this should be the job of torque. Anyway, make selinux permissive is the simplest way of dealing with it.
