A DESTRUCTIVE command to render a drive unbootable
Overwrites the boot sector. Since this doesn't overwrite any data, you can usually recover by re-creating the partition table exactly the same as before you zeroed it. This can also help sometimes if you install a new drive in a Windows machine which can't read it.

show todays svn log
Shows the todays svn log. Perfect for alias usage I assume.

Echo the latest commands from commandlinefu on the console
Self-referential use of wget.

Rapidly invoke an editor to write a long, complex, or tricky command

Create a directory and cd into it
This creates a bash function `take` that you can call with the name of the directory as the first parameter. Add the function to ~/.bashrc to have it available anytime.

Create an SSH SOCKS proxy server on localhost:8000 that will re-start itself if something breaks the connection temporarily
This command will log you into somehost via SSH and then go into the background (-f). From there, you can point e.g. firefox at localhost:8000 as a SOCKS proxy. Autossh will use port 20000 and 20001 to send and receive test data on those ports to ensure the SSH tunnel is still running, and will try to re-start the tunnel if it goes down. Make sure you have ssh-agent running, or passwordless ssh keys distributed between the two hosts.

ping a host until it responds, then play a sound, then exit
After this, just type: $ beepwhenup You need to install "beep" before this would make the beep sound. Save it in your .profile if you want to use it later WARNING: this command won't exit until it is successful. You won't be able to CONTROL+C out of it.

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Get IP from host
I just wanted a simple DNS request. Because host and nslookup commands are not on all systems, we use getent instead. Thanks aulem for that tip.
