A debian-installer is available on a host where a virtual machine is network booted on it. It uses the gallifrey instead of the official. An attempt to apt-get install pf-xivo revealed missing packages that were added to the repository. The meta package pf-xivo was successfully installed.

A naming problem was identified that would prevent upgrading and distributing the packages accross multiple distributions. A new naming convention is proposed for discussion, based on the Debian GNU/Linux backport conventions. The 1.2.40 release of the packaging-farm was published with a documentation for the packaging-farm.conf configuration file and support for Ubunutu natty.
The Practical symfony book is built on an example that can be checked out and installed locally. The tests have been fixed to run successfully with php symfony test:all with help from #symfony, #symfony-fr and François-Emmanuel Lamelliere. The patches have been submitted for inclusion in the repository. It closes the 9472.

When a GNU/Linux machine exhibits a high iowait (i.e. more than 20% of the processor time is locked waiting for IO to complete), it does not always mean a lot of bytes are read or written. It is demonstrated that reading randomly on the disk will create conditions in which less than 5Mb/s are read and the disk will be busy most of the time, which translates into an iowait greater than 20%. A workaround is to give more RAM to the (virtual) machine so that pages read are cached in memory and read only once, therefore reducing the probability of random reads.

When using adbapi with a sqlite backend, it is demonstrated that the memory footprint depends on the number of simultaneous connections running at a given moment. This memory is not reclaimed, but it is reused. On an amd64 processor it approximately amounts to 2KB per simultaneous connection.

The alternate gallifrey repository was assembled from the source and debian GIT repositories and complemented with packages found in the official dak. Some virtual packages ( gallifrey, dahdi-linux-modules, sangoma-wanpipe-modules and misdn-kernel-modules) where hand made. The resulting repository was compared to check for its useability.

Benchmarks using tsung on cardstories showed that long poll requires almost no resources, the server is stable with 25 simultaneous requests served in less than 50ms each and that it overloads when going over 200 simultaneous requests.

The cardstori.es domain was bound to the development machine. A ticketing system and wiki was installed and bound to the git repository. The Debian GNU/Linux package was proposed for inclusion.

When the invitations look like email addresses, the permalink to the game is sent to the corresponding address. The CardstoriesService class was re-architectured for consistency. The interaction and artwork issues were discussed extensively with Xavier Antoviaque and tartarugafeliz. Solutions and new graphics will be provided.

The Xine library Debian GNU/Linux package lintian warnings were fixed. The bug introduced by the lack of v4l support in the 2.6.38 linux kernel was fixed.
