I would write the +numbers down in my little book and compare notes with the other kids +to see how many region codes we had seen and if we had seen some +exotic or special region codes and numbers. It was a fun game to pass +time, as we kids have plenty of it.</p> + +<p>A few days I came across +<a href="https://github.com/openalpr/openalpr">the OpenALPR +project</a>, a free software project to automatically discover and +report license plates in images and video streams, and provide the +"car numbers" in a machine readable format. I've been looking for +such system for a while now, because I believe it is a bad idea that the +<a href="https://en.wikipedia.org/wiki/Automatic_number_plate_recognition">automatic +number plate recognition</a> tool only is available in the hands of +the powerful, and want it to be available also for the powerless to +even the score when it comes to surveillance and sousveillance. I +discovered the developer +<a href="https://bugs.debian.org/747509">wanted to get the tool into +Debian</a>, and as I too wanted it to be in Debian, I volunteered to +help him get it into shape to get the package uploaded into the Debian +archive.</p> + +<p>Today we finally managed to get the package into shape and uploaded +it into Debian, where it currently +<a href="https://ftp-master.debian.org//new/openalpr_2.2.1-1.html">waits +in the NEW queue</a> for review by the Debian ftpmasters.</p> + +<p>I guess you are wondering why on earth such tool would be useful +for the common folks, ie those not running a large government +surveillance system? Well, I plan to put it in a computer on my bike +and in my car, tracking the cars nearby and allowing me to be notified +when number plates on my watch list are discovered. Another use case +was suggested by a friend of mine, who wanted to set it up at his home +to open the car port automatically when it discovered the plate on his +car. When I mentioned it perhaps was a bit foolhardy to allow anyone +capable of placing his license plate number of a piece of cardboard to +open his car port, men replied that it was always unlocked anyway. I +guess for such use case it make sense. I am sure there are other use +cases too, for those with imagination and a vision.</p> + +<p>If you want to build your own version of the Debian package, check +out the upstream git source and symlink ./distros/debian to ./debian/ +before running "debuild" to build the source. Or wait a bit until the +package show up in unstable.</p> + + + Using appstream with isenkram to install hardware related packages in Debian http://people.skolelinux.org/pere/blog/Using_appstream_with_isenkram_to_install_hardware_related_packages_in_Debian.html
