Turns hidden applications transparent in the Mac OS X dock.
In Mac OS X, pressing Command+H will hide an application. While that application's windows vanish, there is no other visual feedback, meaning there is no immediate distinction between an application running with no windows open and a hidden application. This command turns hidden applications' icons transparent, providing a clear and obvious distinction. Change YES to NO to restore the previous functionality.

Installs pip packages defining a proxy

awk date convert
Convert readable date/time with `date` command

Calculate days on which Friday the 13th occurs (inspired from the work of the user justsomeguy)

Console clock

convert video to gif by ffmpeg and imagemagick
you can use any common video format. if you don't need to change the size of gif output, just remove `-vf scale=320:-1` btw, 320:-1 means width is 320px and height would be set automatically

Go to parent directory of filename edited in last command

grep tab chars

"^V" => denotes press control + v and press tab within quotes. $ cat improper_indent.py class Tux(object): print "Hello world.." $ grep " " improper_indent.py print "Hello world.."
