BikeRoute is an Android application providing GPS-based route planning and cycle parking location worldwide. (Google cycle directions in the US, CycleStreet directions in the UK, and Google driving directions elsewhere). It features A to B route planning, nearby cycle parking location, step by step directions, routemap, satnav, and a 'remember where I parked' route finder using data and maps from the OpenStreetMap project.
LocDemo demonstrates the functionality of libwlocate. After startup, it evaluates the current geographic position of the user and displays it within a map. This solution offers geographic localization that works without the use of GPS and without submitting tracking or position data to commercial providers of such services.
desire-adhoc allows you to connect your HTC Desire smartphone to ad-hoc networks. It has been written specifically for the Desire and will not work on other models (unless they use the same network driver, in which case there might be a chance). It requires root access to your phone.
