Here are few more of my weekend diversions, complete with source code and ready to run.


MEOS emulates a command line, similar to what you would see on a Linux or Unix system. Commands are implemented locally and remotely. The client will attempt to find a command handler locally, contacting the server if it is unable to find an appropriate handler.

Here are two examples of MEOS commands.


type "ping <hostname>" on command line to see ping results.

$ ping


To see the whois information for a host, type "whois <hostname>" on the command line

$ whois

May be interesting because of:

Text input widget
Line wrapping
Client/Server communication
Job framework (Non-busy wait multithreading)
URL Encoder
Property file parser

GPS Demo

The GPS Demo use the Location API to find the current coordinates of the device. Once the coordinates are obtained, it communicates with Yahoo Maps (REST) to obtain a URL reference to a map image for the corresponding location. The client downloads the map image, proxied through the image service, and displays it on the device.
