printing barcodes
64 elements max on 16 rows, 4 cols. GNU Barcode will adapt automagically the width and the eight of your elements to fill the page. Standard output format is PostScript.

Testing hard disk reading speed

Takes and displays screenshot of Android phone over adb.
Dependencies on phone: adb access, screencap command, base64 command. Dependencies on computer: adb, sed, base64, display (from imagemagick, but can substitute other image viewer which reads from stdin). This should work around adb stupidies (i.e. that it replaces \n with \r\n) with base64.

Backup your hard drive with dd
This will create an exact duplicate image of your hard drive that you can then restore by simply reversing the "if" & "of" locations. $ sudo dd if=/media/disk/backup/sda.backup of=/dev/sda Alternatively, you can use an SSH connection to do your backups: $dd if=/dev/sda | ssh user@ssh.server.com dd of=~/backup/sda.backup

List programs with open ports and connections
I prefer to use this and not the -n variety, so I get DNS-resolved hostnames. Nice when I'm trying to figure out who's got that port open.

Find and copy scattered mp3 files into one directory
This command copies all filenames in the current dir and subdirs that end in .mp3 regardless of case (also matches .MP3 .mP3 and .Mp3) It copies all the files to the "mp3" folder in your home directory. If you want to see the files that are beeing copied, replace "cp {}" with "cp -v {}"
