Wonder how Apple got the Macbook Air so thin? This is a picture of the hard drive used in it. It’s an SSD, but unlike most SSD’s that use the traditional 2.5 or 1.8″ form factor, this SSD is almost “naked” and will fit in a very small space. Other drive manufacturers will replicate this design soon, but Toshiba was the first.

A friend sent this to me today. Firefox uses a bunch of .sqlite files to manage it’s persistent data like your preferences in the “awesomebar”. These files can get quite big and cause a slow computer when using firefox; especially when using the awesomebar and closing the application.

OS X users can use this command to “compact” these files:

for f in ~/.mozilla/firefox/*/*.sqlite; do sqlite3 $f 'VACUUM;'; done

Windows users can make use of the SQLite addon to do the same thing. Install the addon, then go to %appdata%mozillafirefoxprofilesxxxxx and look for the .sqlite files.
