Bash Initialisation Files
It's incomplete, but probably a reasonable place to start. If you think there's something that desperately need to be fixed then send me email and I'll look at it.

Useful use of cat(1)
Rather special example: This was useful for me on a Redhat Linux, where man(1) otherwise annoyingly would intersperse the output with headers and footers for a print version, which is rarely used, though... I tried: ( echo -e ".pl 1100i"; cat "$1"; echo ".pl \\n(nlu+10\n" ) | tbl | nroff -man

Why I will always love RSS
There has been a lot of noise in the tech community earlier this year about how RSS is supposedly having one foot in the grave. If that would be even remotely true, I hope it dies with its boots on.

Counting Pullups
I'm a big fan of my Fitbit pedometer because it does most of its work without any interaction. I clip it onto my pocket and it counts my steps and flights of stairs as I walk throughout the day, then automatically, wirelessly uploads the data to Fitbit's website whenever I'm within range of its USB dongle plugged into…

I've finally implemented the command I keep typing all day: gti
I've finally implemented the command I keep typing all day: gti. It's a program that displays a badly made ASCII-art animation to punish you for your typing error - and after that magically launches the command you meant to launch.
