Convert PNG to GIF

(relies on 'imagemagick')

Convert all .png files to .gif. This can also go the other way if you reverse the file extensions in the command, e.g.:

for file in *.gif; do convert "$file" "$(basename $file .gif).png"; done

If the file is named 'example1.png' it will be named 'example1.gif' when it is complete.

Convert PDF to JPG

(relies on 'imagemagick')

This command will convert all .pdf files in a directory into a 800px (wide or height, whichever is smaller) image (with the aspect ratio kept) .jpg.

If the file is named 'example1.pdf' it will be named 'example1.jpg' when it is complete.

This is a VERY worthwhile command! People pay hundreds of dollars for this in the Windows world.

My .jpg files average between 150kB to 300kB, but your's may differ.

View your motherboard's ACPI tables (in Debian & Ubuntu)

In July 2008, there was an uproar over Foxconn motherboards feeding Linux installs incorrect ACPI information (http://ubuntu-virginia.ubuntuforums.org/showthread.php?t=869249).

Foxconn has gladly corrected their mistake, but make sure it's not happening on your motherboard!

After running the command, just view the 'dsdt.dsl' in any editor you like.

Turns hidden applications transparent in the Mac OS X dock.

In Mac OS X, pressing Command+H will hide an application. While that application's windows vanish, there is no other visual feedback, meaning there is no immediate distinction between an application running with no windows open and a hidden application. This command turns hidden applications' icons transparent, providing a clear and obvious distinction.

Change YES to NO to restore the previous functionality.
