Sometimes a bunch of unwanted files end up somewhere they don't belong. Maybe a cp gone wrong, or other command line typo creates a slew of oddly named files -- but you've got a number of files you'd really like to keep around mixed in with the bad. The following

Dropbox is a great tool for keep your digital life in sync, but sometimes you only have CLI access to a system where you're running Dropbox. Luckily Dropbox has a pretty slick python script that allows you to check up and control your Dropbox instance: dropbox.py [http://www.dropbox.
