From Fred Stutzman, who is looking for network-free moments in which to 'code, write or create':

In an attempt to resist the encroachment of network into the spaces of productivity, I've created Freedom. Freedom is a Mac application that disables your computer's networking capabilities for a selected time interval. Some of you may turn off your network when you need to be productive; I've done that, but always found myself popping the network on at my next break (and losing 20 minutes to YouTube/Wikipedia/etc). Freedom takes this approach a step further, locking you out of your network for your selected time interval; Freedom enforces freedom.
