DSOM: shotdetect – scene change detector

Similar to DOPOM, that I mentioned in a previous post, I would also like to start DSOM (Debian Sponsoring Of the Month). As I still remember the times when I was looking for a sponsor for my packages, I would like to make that time a bit more pleasant to future DMs or DDs. So each month I pick at least one RFS or something similar and try to make the package fit for upload.

Of course you could also send me an email to dsom@alteholz.eu and advertise your package.

This month I have choosen shotdetect, a scene change detector in movies. It is already available in unstable so more information are available on the PTS page.

meep in Debian

Currently there are three implementations of MPI  available in Debian. They are openmpi, mpich2, and lam4. After mpich1 had been removed, only the openmpi-version of meep remained (of course the serial version just called meep is also still available). I now closed that gap and uploaded the mpich2- and lam4 version to Unstable. As I have’t found a corresponding version of libhdf5, I had to use the serial version of that lib for these packages.

Further a package depending on mpi-default is now available. So you can either choose a version of meep linked to a specific MPI lib or just use the version that the mpi-default-maintainer thinks is the best version of a given architecture.

This is my first post that was written mainly on a smartphone. I guess I really need to feel boring before I do this again :-).

DOPOM: ent – pseudorandom number sequence test program

This is my first DOPOM (Debian Orphaned Package Of the Month) package.  I am trying to find an orphaned package every month and take over the responsibilty for it.

As I recently got some Entropy Keys from Simtec Electroniscs to muck around, this package very well fits in my future work.

So what is the entropy of Debian?

$ echo "Debian GNU/Linux"|ent
Entropy = 3.852169 bits per byte.

Optimum compression would reduce the size
of this 17 byte file by 51 percent.

Chi square distribution for 17 samples is 299.24, and randomly
would exceed this value 5.00 percent of the times.

Arithmetic mean value of data bytes is 84.1176 (127.5 = random).
Monte Carlo value for Pi is 4.000000000 (error 27.32 percent).
Serial correlation coefficient is 0.095764 (totally uncorrelated = 0.0).
