Install your ssh key file on a remote system

Simply copies your public key to the remote system. For the first time, this will require a password for the user@remote account. From then on, ssh will ask for your private key keyphrase occasionally but you won't need to use the password. Very handy when you're moving files for testing etc.

Reset hosed terminal,

stty sane resets the tty to basic usable function. The ^J is a newline -- sometimes CR/LF interpretation is broken so use the ^J explicitly.

Salvage a borked terminal

This is more or less the same as 'reset', but with two advantages: the initial LF character makes sure you're starting a new line to the tty driver, the final one is more reliably a line-end as CR is often unset; and second, 'stty sane' is reliable on older UNIX systems, especially Berkeley-based ones.

Puts every word from a file into a new line

Simply translates whitespace to newlines. Could be enhanced to compress out extra newlines, but that might be better handled in the next tool down the pipe, with eg uniq(1).
This is sample output - yours may be different.

Simple Video Surveillance by email

This takes a picture (with the web cam) every 5 minutes, and send the picture to your e-mail.

For instance with Gmail, emails sent to me+trash@gmail.com can be filtered with "Matches: DeliveredTo:me+trash@gmail.com"
