Freifunk auf den Chemnitzer Linuxtagen 2012

Klaus Kruse stellt auf den diesjährigen Chemnitzer Linuxtagen Freifunk vor. Die Chemnitzer Linux-Tage sind die zweitgrößte Veranstaltung zum Thema Linux und Open Source in Deutschland.  Die Veranstaltung dreht sich rund um das Thema Linux und Open Source für jedermann. Sie wird vom IN Chemnitz, der CLUG, dem Rechenzentrum und der Fakultät für Informatik der TU Chemnitz und vielen freiwilligen Helfern durchgeführt.

Der Vortrag findet am Sonntag dem 18. März um 16:30 im Raum V3 statt.

Hier der Ankündigungstext:

Freifunk – drahtlose Community-Netzwerke. Unter dem Label «Freifunk» existiert eine deutschlandweite Bewegung, die vor Ort freie und offene WLAN-Netzwerke aufbaut. Zum Einsatz kommen Standardrouter und angepasste Firmware auf der Basis von OpenWRT. Der Vortrag zeigt die Motivation, wie die Technik funktioniert und wie sich jeder selbst am Aufbau eines Freifunk-Netzwerkes beteiligen kann.

Adresse des Events:
Hörsaal- und Seminar-Gebäude der Technischen Universität Chemnitz

freifunk at the CeBIT 2012

The CeBIT and Linux New Media are sponsoring Free/Open Source Projects to join the CeBIT from March 6-10 in Hannover, Germany. Freifunk was accepted as an Open Source organization. We have a booth and already have a confirmation of some Italien friends from the Ninux community who will join as well. 

I have set up a Wiki page for everyone who would like to help with the organization.

Preparations and communications are running over the following channel:

The organizers already confirmed to us, that we will have power supply and Internet. "Connectivity will be by network cable, not by WiFi." I think we can take care of that.

Wireless Battle Mesh v5 in Greece - Call for papers

Wireless Battle Mesh v5 is at hand and it is time to bring together the agenda. As last year's attempts to construct an agenda was well received and provided the grounds for numerous healthy discussions the broad majority asked for similar action. However, the number of talks is going to be reduced to leave more time for individual discussions and testing.



To allow an efficient handling of your submission, please provide the following information and send them to me directly in form of an email:

* your name

* the type of your slot (talk/workshop/panel discussion/lightening talk)

* your topic headline

* your topic description which can brief (does not need to exceed a couple of lines) but should provide a reasonable summary of your talk

* the dates of your stay at the event + (optional) preferred day for your slot

* length of the slot if you wish to do a workshop (all other slots will be limited to one hour - notify me in advance if you think that is not enough for you)

Feel free to contact me with your ideas in case you are unsure about your topic. Last year's agenda also should be able to provide some insights:



Submissions are accepted until and including the 16th of March. Everyone missing this deadline still has the opportunity to apply for a lightening talk slot. These slots can be acquired by simply contacting me during the event. The list of registered lightening talks will be published in the battlemesh wiki.

The final program will be made available in the aforementioned wiki during the second week of March.

GSoC 2011: Videochat for Diaspora with Vittorio

I’m writing about the results achieved with my Google Summer of Code project, for the Ninux community, under the umbrella of Freifunk (I thank them both for the opportunity they gave me).Briefly it consisted in developing a video chat feature for Diaspora*, a distributed social network.This project has received a very big feedback and appreciations from the entire Diaspora community, including the core team, who helped and supported me during the development.Basically, it provides two new functionalities to the Diaspora engine:

  • Textual chat, based on XMPP signaling protocol
  • Video chat, using Jingle XEP

Both have been developed in Javascript, with some Rails code. It usesStrophe.js library for the textual chat, based on XMPP Over BOSH standard, and a self-made extension of it to realize Jingleprotocol.The project includes a custom ejabberd module in Erlang for the integration of ejabberd/diaspora databases, an Actionscript part for the video chat stuff and an external authentication script written in Ruby used by ejabberd to authenticate users from Diaspora.The project has been split in two pull requests, and we’re currently fixing them before merge with master repository: [1],  [2].Source code can be found at, under “jabber” and “video_chat” branches.Setup instructions here. Some screen-shots: [1], [2], [3].I hope it will be soon merged and improved by me and the community, to make it available on every Diaspora* pod!Vittorio**This article appeared first on the website of Ninux, our friends from Italy:
