			<content:encoded><![CDATA[<p>Hi,<br />
26c3 is over and we had quite some experiments going on. Not everything went good, but we learned a lot:</p>
<ul>
<li>babel did not survive the hack-center.</li>
<li>ahcp did survive.</li>
<li>measurement needs to be improved</li>
</ul>
<p>That does not sound much, but i think it&#8217;s valuable information as we can now concentrate on some things and forget the other.</p>
<p>Openimp did not run good, it had a memory leak we got not fixed during 26c3, so the router kept rebooting after a few minutes.<br />
Babel also hat real trouble, it ate up a lot of cpu and memory, it felt like olsr 3 years ago.<br />
A few harddrives did not survive the heat of colo, so a part of the topology data are maybe lost.<br />
Firmware building and development did work quite good, but could be better, that was mainly my verpeilung, there is room for improvement.</p>
<p>I will continiue the tests in my local mesh neighbourhood without babel and without ipv4 based olsr, so expect more firmware builds soon.</p>

			<content:encoded><![CDATA[<p>Gestern auf dem easterhegg angekommen, heute schon die erste überraschung: das hamburger chaos hat sich an xing verkauft, laut mcfly bekommen sie pro xing lanyard ca. 5 euro in die kasse.</p>
<p>Schade, bisher hatten die hamburger das nicht nötig und waren in der lage vernünftig zu wirtschaften.</p>
<p>Ansonsten bisher alles sehr entspannt, die ersten freifunker und OpenWrtler sind angekommen und wir richten uns im freifunk/wireless raum ein.</p>

			<content:encoded><![CDATA[<p>The <a title="25c3" href="http://events.ccc.de/congress/2008/">25th chaos communication congress</a> is coming and the wireless community will be there. This time, we got a nice cosy space in the famous hackcenter, in the <a title="Wireless" href="https://events.ccc.de/congress/2008/wiki/Wireless">Wireless corner</a>.</p>
<p>We will be right next to other interesting project like:</p>
<ul>
<li><a title="GSM" href="https://events.ccc.de/congress/2008/wiki/GSM">GSM Hackers</a></li>
<li><a title="Console Hackers" href="https://events.ccc.de/congress/2008/wiki/Console_Hacking">Console Hacking</a></li>
<li>The <a title="Bricophone" href="https://events.ccc.de/congress/2008/wiki/Bricophone">Bricophone</a> people</li>
</ul>
<p>More on the <a title="Floorplans" href="https://events.ccc.de/congress/2008/wiki/Floorplans">floorplan</a>.</p>
<p>We are going to build a <a title="ipv6 siit mesh" href="https://events.ccc.de/congress/2008/wiki/Wireless:6Mesh">ipv6 only</a> mesh using siit to transport translated ipv4 traffic.</p>
<p>So, preparation are happening all over, even if you can see them only if you have a very close look:</p>
<p>Jow is <a title="luci ticket" href="http://luci.subsignal.org/trac/changeset/3929">fixing</a> <a title="even more" href="http://luci.subsignal.org/trac/changeset/3928">tickets</a> and enhancing the <a title="luci" href="http://luci.subsignal.org/trac/wiki">openwrt luci framework</a> to make sure we have a good start into the experiment.</p>
<p>Meanwhile, <a title="leo34" href="http://blog.leo34.net/">Daniel</a> is working hard on our BGP routers to make sure we get a direct routing for the freifunk <a title="ripe whois" href="http://www.db.ripe.net/whois?form_type=simple&amp;full_query_string=&amp;searchtext=77.87.48.1&amp;do_search=Search">PI</a> network into the 25c3. As you can see, our <a title="freifunk AS" href="http://www.db.ripe.net/whois?form_type=simple&amp;full_query_string=&amp;searchtext=AS44194&amp;submit.x=0&amp;submit.y=0&amp;submit=Search">RIPE</a> entry has been updated to enable routing to and from <a title="AS249" href="http://www.db.ripe.net/whois?form_type=simple&amp;full_query_string=&amp;searchtext=AS249&amp;do_search=Search">AS249</a>, the congress network.</p>
<p>Felix has ported the siit kernel module to kernel 2.6 and <a title="siit commit" href="https://dev.openwrt.org/changeset/13730">commited</a>.</p>
<p><a title="Helox" href="http://no-route.org/blog/">Lehox</a> and friends are working hard on <a title="n2n p2p vpn" href="http://www.ntop.org/n2n/">n2n</a> to get at least the worst bugs fixed, as we are going to use it as the backup vpn to our other BGP routers.</p>
<p>There is still a lot to do, but it looks like we are on a good way.</p>

			<content:encoded><![CDATA[<p>Founding hackerspaces might become a hobby, as i just took part in the founding 2 hackerspaces.</p>
<p>The first on was on thursday, the founding of the <a href="http://sublab.org/">sublab</a>, a hackerspace in leipzig in the <a href="http://www.westwerk-leipzig.de/">Westwerk</a>.</p>
<p>Good feeling, a bunch of about 30 young motivated people from many different groups in leipzig. Some were surprised about the the good feedback after publishing the idea of a hackerspace, as leipzig is a rather small town.</p>
<p>Founding  groups are <a href="https://c3le.de/">chaostreff leipzig</a>, <a href="http://leipzig.freifunk.net/">Freifunk Leipzig</a>, <a href="http://leipzigerkamera.twoday.net/">Leipziger Kamera</a>, the wikipedia people, the <a href="http://gaos.org/moin/LeipzigerLinuxUserGroup">linux user group</a>, <a href="http://www.mikrokopter.de/ucwiki/LeipZig">Open Source Drone Crew Leipzig</a>, the group against <a href="http://leipzig.vorratsdatenspeicherung.de/">data retention</a> and they are getting more.</p>
<p>Some older pictures of  hard working people: <a href="http://www.diac24.net/bilder/foobar/">http://www.diac24.net/bilder/foobar/</a> and on <a href="http://www.flickr.com/photos/bascht/tags/sublab/">flickr</a>, more groups are interested and coming.</p>
<p>After a short visit to the Mitgliederversammlung of <a href="http://www.c-base.org/">c-base</a> e.V. on friday, i went to hamburg to the <a href="http://hamburg.ccc.de">ccc</a> hamburg, to the next founding of a Hackerspace.</p>
<p>After thinning out a list of more than 50 potential names, it got the name Attraktor e.V., which is the german word for <a href="http://en.wikipedia.org/wiki/Attractor">attractor</a>, to relate to the chaostheory.</p>
<p>Founded by 10 members of the ccc hamburg and a member of <a href="http://www.ssdev.org">ssdev</a> e.V., they want to rent a room for many groups in hamburg to collaborate, talks have been done with AK Voratsdatenspeicherung.</p>
<p>The executive board consists of 3 ccc members, one lockpicker and one &#8220;free&#8221; member.</p>
<p>Good luck for both, there is a lot of work to do.</p>
<p>Update:</p>
<p>attraktor is finally <a title="Attraktor" href="http://www.attraktor.org/" target="_self">online</a>.</p>

<p>zeugs aufgebaut:</p>
