Compute running average for a column of numbers
This is an on-line algorithm for calculating the mean value for numbers in a column. Also known as "running average" or "moving average".

put an unpacked .deb package back together
If any changes have been made to the package while it was unpacked (ie, conffiles files in /etc modi‐fied), the new package will inherit the changes. This way you can make it easy to copy packages from one computer to another, or to recreate packages that are installed on your system, but no longer available elsewhere. Note: dpkg-repack will place the created package in the current directory.

Geolocate a given IP address
Defines a function to geolocate a given IP address; if none supplied, will default to your external IP address.

Make a DVD ISO Image from a VIDEO_TS folder on MacOSX
/path/ is the root folder of the DVD, not the VIDEO_TS folder.

Execute MySQL query send results from stdout to CSV
You can, of course, tell MySQL to output results to a file and dictate how to terminate lines, etc. But sometimes you don't have access to the file system MySQL is running on, complicating outputting your results to a CSV, necessitating either annoying hacks or this simple command :D

Produce a pseudo random password with given length in base 64
Of course you will have to install Digest::SHA and perl before this will work :) Maximum length is 43 for SHA256. If you need more, use SHA512 or the hexadecimal form: sha256_hex()

Put readline into vi mode
This lets you use your favorite vi edit keys to navigate your term. To set it permanently, put "set editing-mode vi" in your ~/.inputrc or /etc/inputrc.

capture selected window

Create a html of information about you harddisk

Keep one instance of an irc chat client in a screen session
This command attempts to attach to existing irssi session, if one exists, otherwise creates one. I use "irc" because I use different irc clients depending on what system I am working on. Consistency is queen.
