Check These Out

HDD Performance Write Test
Test your XFS filesystem and Raptor hard drives for write performance.

Merge files, joining each line in one line

archive all files containing local changes (svn)
This works more reliable for me ("cut -c 8-" had one more space, so it did not work)

Set all CPU cores' CPU frequency scaling governor to maximum performance

save your current environment as a bunch of defaults

Count lines of source code excluding blank lines and comments
Much more accurate than other methods mentioned here straight out of the box.

Google text-to-speech in mp3 format

Archive all SVN repositories in platform indepenent form
Use of hotcopy for safety/stability of the backups.

Write comments to your history.
A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.

Dump dvd from a different machine onto this one.
You can use this to directly dump from machine A (with dvd drive) to machine B (without dvd drive) . I used this to copy dvd using my friend's machine to my netbook. Above command is to be issued on machine B. Advantages : 1) No wasting time dumping first to machine A and then copying to Machine B. 2) You dont need to use space on Machine A. In fact, this will work even when Machine A doesnt have enough hdd space to dump the DVD. Use -C ssh option on slow networks (enables compression). you can replace "dd if=/dev/dvd" with any ripping command as long as it spews the iso to stdout.
