The Freifunk Wireless Community Weekend 2008 is over. I had a fantastic time meeting so many people pushing the idea of free networks to new hights. The interest in free wireless was overwhelming and we probably had more than double the number of the 51 visitors who put their names on the participants list. Many developers were taking part. We saw presentations about OpenWRT, B.A.T.M.A.N., the HorstTool, mikroFM, OpenHardware and the Luci-Interface for Freifunk networks. Receiving questions about "free networks and the implications of the law" regularly, we were extremely pleased that Reto Mantz recently published a doctoral thesis about this subject and held a presentation at the WCW (slides now available).

Besides German communities we were very happy to meet many friends from other countries like www.guifi.net from Catalunia, Spain, Sergey Yugov from Russia, Jesper Svarre with 28 people from Denmark and our friends from the Rome community ninux.org.

Together with the help of Italian and German Freifunkers Saverio and me made tons of interviews. Be sure it will not take two years this time to see them online ;-) Get a little taste of the WCW2008 with the first of a series of videos already published by our Italian friends.

Per ora vi lascio con questo breve video, che mostra qualche immagine della domenicale del Wireless Community Weekend. Molto presto verranno pubblicate le interviste. (http://blog.ninux.org/2008/05/05/lultima-sera-al-wcw2008/)

The countdown for the Freifunk Wireless Community Weekend 2008 conference is running and cven is haevily working on the final preparation.

As of now we have 48 people who have put their name on the participants list on the wiki at http://wiki.freifunk.net/WCW08:participants and many more who have confirmed their participation to us directly. People are joining us in the upcoming days from Freifunk communities from all over Germany and from communities in other countries. Our friends from Italy will be represented by the two well known free wireless evangelists Nino and Saverio from ninux.org and we expect Jesper Svarre from Denmark with a group of 25 people from the Association of Computer Professionals.

The WCW is a self organized conference and community gathering. We will have a community track with communities presenting themselves, e.g. from Bastian from the Weimar Freifunkers and from Keks from the community in Berlin North-East.

On the other side there will be technical talks from developers of OpenWRT, the B.A.T.M.A.N. routing protocol developers Marek Lindner and Simon Wunderlich; Thomas Hirsch - the developer of the freimap and a presentation of sven-ola - the main developer of the Freifunk Firmware,

Further panels cover subjects like Web 2.0 in the Freifunk Universe (by me, Mario Behling) or Open Networks and the current law by Dr. Reto Mantz, who has recently published a book on "Offene Netze und Recht",

Many opportunities to meet with some of the most exciting people in the international freifunk sphere! Open Mesh advocat Electra will take part in the WCW and after returning from the Open Tech Summit in Taiwan Juergen Neumann will present the latest advancements on Open Wireless Hardware. 

Last but not least we are happy to welcome participants from the academic scene coming from the TU Berlin and the Fraunhofer FOKUS Institute.

Join us at the Freifunki Wireless Community Weekend in Berlin from May 2-4! Check out the latest updates on http://wiki.freifunk.net/Wireless_Community_Weekend_2008

Marek Lindner and Simon Wunderlich from the Berlin freifunk community gave a talk on Wireless Kernel Tweaking and the B.A.T.M.A.N. routing protocol at the 24c3 Chaos Communication Congress. The video is now available on the torrent network. I also uploaded it to Google Video.

Morgen, am 27. Dezember beginnt der 24. Chaos Communication Congress (24c3) im Berliner Congress Center am Alexanderplatz unter dem Motto Volldampf voraus!

Der Kongress dauert bis zum 30. Dezember. Die Freifunk-Community trifft sich hier unter anderem in der Embedded Corner auf der Ebene C im ersten Stock neben der Treppe. Im Wiki haben sich bereits Freifunker aus Bern, Hamburg, Leipzig, Rostock sowie der Berliner Initiativen aus der City, vom Kiezfunk und aus Berlin Nordost angekündigt. Themen werden die aktuelle Firmware, die Erfahrungen mit dem neuen Routingprotokoll B.A.T.M.A.N. und die Idee der Open Hardware Prism sein.

Wir freuen uns auch auf interessante Zusammentreffen mit "wireless groups from all over", Gnu Radio, Decentral applications/protocols, Openembedded, Opemmoko, Settopfoo und vielen anderen.

Just wurde nach langem Werkeln in Leipzig eine neue stable Firmware (1.6.10-a) veröffentlicht. Im Leipziger Mesh kann diese über die automatische Updatefunktion (ab 1.4.5) per Klick geladen werden, im www unter http://firmware.leipzig.freifunk.net In dieser Firmware wird erstmalig batmand konsequent als "Zweitmesh" eingesetzt. Batman selbst trifft (noch) keine Routing-Entscheidungen, die Tunnel zu Gateways sind abgeschaltet, damit der OLSR-Betrieb nicht gestört wird. Es wird fleissig beobachtet und debugged. Designtechnisch kommt die FW im schwarzen Look der cccamp07-Firmware daher. Ausserdem: Update-Warnung auch für einzelne Pakete, neuer Statistik-Feel und viele Kleinigkeiten. Thanx to Tetzlav und Jo.

Schon in Chaosradio Express 016 hat Elektra einen tiefen Einblick in Wesen und Form des Mesh Networking geboten. Im Gespräch mit Tim Pritlove werden nun die neuesten Erkenntnisse der Entwicklung berichtet. Kern der Neuigkeiten ist der Nachfolger des OLSR-Protokolls namens B.A.T.M.A.N. Elektra erläutert, wie B.A.T.M.A.N. im Deatil funktioniert, welche Erfahrungen und Erkenntnisse seinem Design zu Grunde liegen und wie man sich das alles vorstellen muss. Ein Teil der Diskussion betrifft auch die geplante Mesh Networking Technologie im OLPC (XO) Laptop. (20.9.2007, http://chaosradio.ccc.de/cre045.html)

Aus dem von elektra verfassten Buch "Mesh", welches Anfang August bei opensourcepress.de erschienen ist, gibt es jetzt das Kapitel über B.A.T.M.A.N als pdf-Download: https://www.opensourcepress.de/fileadmin/osp/pdf/mesh_leseprobe.pdf
Ausserdem beim EDV-Buchversand das Vorwort als Teaser...!

Am letzten Sonntag liefen auf Rundfreifunk Interviews von der B.A.T.M.A.N.-Release-Party. Die Party fand auf der c-base in Berlin statt. Die Sendung findet man nun auch online unter http://www.public-ip.org/sendung-170.html. Darin unter anderem Interviews mit: Elektra, Sven-Ola., Tetzlav, Ludger und Poelzi zu OLSR, BATMAN, Firewalls und Puffer-/Pollraten...

Rundfreifunk sendet in Leipzig auf UKW und im Internet unter http://rund.freifunk.net und http://www.public-ip.org.

Viel Spaß beim Hören!

The B.A.T.M.A.N.-developer team would be happy to celebrate with YOU the 0.2 release of B.A.T.M.A.N. at the C-Base (in Berlin). FYI, there will also be a free barrel of cool beer waiting to be flushed. Version 0.2 can reasonably be called stable now. It works quite performant, supports multiple interfaces, has a low CPU-load, a robustly working algorithm underneath, and autonomously negotiates UDP-Tunnels to GWs  which ultimately enables long-term and stable internet connections. A number of users reported quite excitedly about the amazing experiences they made with this protocol. Well, we want to stay neutral so join in to hear them and try batman for yourself.

Currently B.A.T.M.A.N is available for Linux only. The ports for Mac OS-X and BSD have fallen asleep and are waiting for a diligent bee ... Maybe there will once also exist a windows port.

Many thanks to all the people who helped to realize this in such a short amount of time.
