BT747 - New code signatures

The code signing key used for BT747 had to be upgraded to SHA-256.

Unfortunately that also revoked the old key and apparently the timestamping was not properly done with the previous signatures.  So the java laucher complains that the certificate is revoked.

All files have been resigned and republished.

You may need to launch:

javaws -viewer

[on windows : "Windows Key + R" to access the execute popup where you can enter this].

Is your GPRS Tracker safe ?

When you want to know where you've been using GPS, you basically have two options: active tracking and passive tracking.

Passive tracking is what most users of this site are doing: an electronic devices stores the positions internally and these positions are recovered at  a later time.

Active tracking generally implies the transmission of the current position to some kind of server in "real time".  And that is most of the time done using the GSM/GPRS network.

Tracking dogs - CollierGPS

Collier GPSCollier GPS

When I discovered about 'Kookoo', the tracked cat back in May, I had no idea that I was going to work on a project to track dogs.  And yet, I did.

If you are interested in this amazingly well designed collar, you can find more information in French at http://www.colliergps.fr and a demonstration of the interface, but here is my story:

GPSLog Labs - Another site to share tracks

GPSLog Labs is another site where you can store your tracks that is well worth a visit.  It analyses your track to find positions where you stopped and splits the track in several subsections.

The site is pretty responsive too.

I added this to the list of sites where you can share your tracks.

Open Route Service

I discovered an 'open' service that I did not know about yet: Open Route Service.   The site demonstrates the route calculation between two positions on the map.  I did not test it a lot, but I will likely look into it later.

If you test it more before I do, do not hesitate to leave a comment.
