Tip: Calculate distance between two GPS endpoints on Blackberry

If you are in need of determining the distance between two geo coordinates on blackberry, use the following piece of code.

====
import javax.microedition.location.Coordinates;

private double difference( double currentLat, double currentLon, double startLat, double startLon )
{
Coordinates current = new Coordinates(currentLat, currentLon, 0);
Coordinates start = new Coordinates(startLat, startLon, 0);
float diffInMetres = current.distance(start);
return diffInMetres * 0.000621371192; //Convert into miles
}

Tip: Eclipse and Linux Installation Troubleshoot

Problem: After installing Eclipse on Linux, if you get:
"Failed to load the JNI shared library /usr/java/jdk1.6.0_23/jre/bin/../lib/i386/client/libjvm.so"

or

Solution:

If you have sudo rights,
$> sudo chcon -t execmem_exec_t '/opt/eclipse/eclipse'
