For centuries, ships navigated by the stars. Thousands of ships' logs representing hundreds of thousands of position readings were diligently recorded by sailors for a future use they never could have imagined: 100 years of ocean travel 1750 to 1850.

GPX riding is a general term for using a GPS device to track and record location while riding a bicycle [previously on MetaFilter

uses GPS to tell you the predicted time of the next bus. Google maps show buses in real time, and you can get updates on your phone/PDA. The coverage is limited to certain agencies within the US, so these other sites might be useful: Hopstop
covers subways and buses in NYC, Boston, Chicago, San Francisco, DC, and more. (mobile version
) Google Transit
has many US metro areas in addition to Canada, Europe, and Japan. (previously)
