Social messaging progress

Development of the social messaging system component of GNUnet is making progress.

Now the PSYCstore is able to perform state assignment operations and local applications can request stored state variables from it.

The social service and its API is ready to use now. It allows applications to host and enter places, send & receive messages, as well as access the history and stored state of places. The social API also uses the GNU Name System for the naming of places.

This downtime implies that this website, subversion server, hostlist server, Mumble server, and your email (if you are using will all be unavailable during the maintenance period. Other services such as IRC (#gnunet) and mailing lists are not effected.

There is a slight possibility that the downtime is going to be longer than expected. If that happens to be the case, it will be informed via mailing list.

Hi devs,

On the 27th we get to officially announce the results from the GSoC application process to the students, so we should probably use this opportunity to also have a first discussion with those that have been selected. So, let's have the 6th develper Mumble on Monday, April 27th, 9pm CEST, as usual using the Mumble server on Agenda items include:

  • GSoC announcements and planning
  • GNUnet 0.10.2 release: To CADET or not to CADET?

I hope all GSoC applicants, mentors and Bart can make it, naturally everybody is welcome to join.
