+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/_pent_m_te_p__onsdag_om_bruken_av_Microsoft_Exchange_ved_Universitetet_i_Oslo.html&quot;&gt;skrev
+i juni om protestene&lt;/a&gt; på planene til min arbeidsplass,
+&lt;a href=&quot;http://www.uio.no/&quot;&gt;Universitetet i Oslo&lt;/a&gt;, om å gå bort fra
+fri programvare- og åpne standardløsninger for å håndtere epost,
+vekk fra IETF-standarden SIEVE for filtrering av epost og over til
+godseide spesifikasjoner og epostsystemet Microsoft Exchange.
+Protestene har fått litt ny omtale i media de siste dagene, i tillegg
+til de oppslagene som kom i mai.&lt;/p&gt;

+
+&lt;/ul&gt;
+
+&lt;p&gt;Prosjektledelsen har fortalt at dette skal fungere like godt for
+Linux-brukere som for brukere av Microsoft Windows og Apple MacOSX,
+men jeg lurer på hva slags erfaringer Linux-brukere i eksisterende
+miljøer som bruker MS Exchange har gjort.  Hvis du har slik erfaring
+hadet det vært veldig fint om du kan send et leserbrev til
+&lt;a href=&quot;http://www.uniforum.uio.no/&quot;&gt;Uniforum&lt;/a&gt; og fortelle om hvor
+greit det er å bruke Exchange i kryss-platform-miljøer?  De jeg har
+snakket med sier en greit får lest e-posten sin hvis Exchange har
+slått på IMAP-funksjonalitet, men at kalender og møtebooking ikke
+fungerer godt for Linux-klienter. Jeg har ingen personlig erfaring å
+komme med, så jeg er nysgjerrig på hva andre kan dele av erfaringer
+med universitetet.&lt;/p&gt;
+
+&lt;p&gt;Mitt ankerpunkt mot å bytte ut fri programvare som fungerer godt
+med godseid programvare er at en mister kontroll over egen
+infrastruktur, låser seg inn i en løsning det vil bli dyrt å komme ut
+av, uten at en får funksjonalitet en ikke kunne skaffet seg med fri
+programvare, eventuelt videreutviklet med de pengene som brukes på
+overgangen til MS Exchange.  Personlig planlegger jeg å fortsette å
+laste ned all eposten min til lokal maskin for indeksering og lesing
+med &lt;a href==&quot;http://notmuchmail.org&quot;&gt;notmuch&lt;/a&gt;, så jeg håper jeg
+ikke blir veldig skadelidende av overgangen.&lt;/p&gt;

+åpen for de som vil signere på oppropet.  Akkurat nå er det 298

-               <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/A_Raspberry_Pi_based_batman_adv_Mesh_network_node.html</guid>
-                <pubDate>Mon, 21 Oct 2013 11:40:00 +0200</pubDate>
-               <description>&lt;p&gt;The last few days I have been experimenting with
-&lt;a href=&quot;http://www.open-mesh.org/projects/batman-adv/wiki&quot;&gt;the
-batman-adv mesh technology&lt;/a&gt;.  I want to gain some experience to see
-if it will fit &lt;a href=&quot;https://wiki.debian.org/FreedomBox&quot;&gt;the
-Freedombox project&lt;/a&gt;, and together with my neighbors try to build a
-mesh network around the park where I live.  Batman-adv is a layer 2
-mesh system (&quot;ethernet&quot; in other words), where the mesh network appear
-as if all the mesh clients are connected to the same switch.&lt;/p&gt;
-
-&lt;p&gt;My hardware of choice was the Linksys WRT54GL routers I had lying
-around, but I&#39;ve been unable to get them working with batman-adv.  So
-instead, I started playing with a
-&lt;a href=&quot;http://www.raspberrypi.org/&quot;&gt;Raspberry Pi&lt;/a&gt;, and tried to
-get it working as a mesh node.  My idea is to use it to create a mesh
-node which function as a switch port, where everything connected to
-the Raspberry Pi ethernet plug is connected (bridged) to the mesh
-network.  This allow me to hook a wifi base station like the Linksys
-WRT54GL to the mesh by plugging it into a Raspberry Pi, and allow
-non-mesh clients to hook up to the mesh.  This in turn is useful for
-Android phones using &lt;a href=&quot;http://servalproject.org/&quot;&gt;the Serval
-Project&lt;/a&gt; voip client, allowing every one around the playground to
-phone and message each other for free.  The reason is that Android
-phones do not see ad-hoc wifi networks (they are filtered away from
-the GUI view), and can not join the mesh without being rooted.  But if
-they are connected using a normal wifi base station, they can talk to
-every client on the local network.&lt;/p&gt;
-
-&lt;p&gt;To get this working, I&#39;ve created a debian package
-&lt;a href=&quot;https://github.com/petterreinholdtsen/meshfx-node&quot;&gt;meshfx-node&lt;/a&gt;
-and a script
-&lt;a href=&quot;https://github.com/petterreinholdtsen/meshfx-node/blob/master/build-rpi-mesh-node&quot;&gt;build-rpi-mesh-node&lt;/a&gt;
-to create the Raspberry Pi boot image.  I&#39;m using Debian Jessie (and
-not Raspbian), to get more control over the packages available.
-Unfortunately a huge binary blob need to be inserted into the boot
-image to get it booting, but I&#39;ll ignore that for now.  Also, as
-Debian lack support for the CPU features available in the Raspberry
-Pi, the system do not use the hardware floating point unit.  I hope
-the routing performance isn&#39;t affected by the lack of hardware FPU
-support.&lt;/p&gt;
-
-&lt;p&gt;To create an image, run the following with a sudo enabled user
-after inserting the target SD card into the build machine:&lt;/p&gt;
-
-&lt;p&gt;&lt;pre&gt;
-% wget -O build-rpi-mesh-node \
-    https://raw.github.com/petterreinholdtsen/meshfx-node/master/build-rpi-mesh-node
-% sudo bash -x ./build-rpi-mesh-node &gt; build.log 2&gt;&amp;1
-% dd if=/root/rpi/rpi_basic_jessie_$(date +%Y%m%d).img of=/dev/mmcblk0 bs=1M
-%
-&lt;/pre&gt;&lt;/p&gt;
-
-&lt;p&gt;Booting with the resulting SD card on a Raspberry PI with a USB
-wifi card inserted should give you a mesh node.  At least it does for
-me with a the wifi card I am using. The default mesh settings are the
-ones used by the Oslo mesh project at Hackeriet, as I mentioned in
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Oslo_community_mesh_network___with_NUUG_and_Hackeriet_at_Hausmania.html&quot;&gt;an
-earlier blog post about this mesh testing&lt;/a&gt;.&lt;/p&gt;
-
-&lt;p&gt;The mesh node was not horribly expensive either.  I bought
-everything over the counter in shops nearby.  If I had ordered online
-from the lowest bidder, the price should be significantly lower:&lt;/p&gt;
-
-&lt;p&gt;&lt;table&gt;
-
-&lt;tr&gt;&lt;th&gt;Supplier&lt;/th&gt;&lt;th&gt;Model&lt;/th&gt;&lt;th&gt;NOK&lt;/th&gt;&lt;/tr&gt;
-&lt;tr&gt;&lt;td&gt;Teknikkmagasinet&lt;/td&gt;&lt;td&gt;Raspberry Pi model B&lt;/td&gt;&lt;td&gt;349.90&lt;/td&gt;&lt;/tr&gt;
-&lt;tr&gt;&lt;td&gt;Teknikkmagasinet&lt;/td&gt;&lt;td&gt;Raspberry Pi type B case&lt;/td&gt;&lt;td&gt;99.90&lt;/td&gt;&lt;/tr&gt;
-&lt;tr&gt;&lt;td&gt;Lefdal&lt;/td&gt;&lt;td&gt;Jensen Air:Link 25150&lt;/td&gt;&lt;td&gt;295.-&lt;/td&gt;&lt;/tr&gt;
-&lt;tr&gt;&lt;td&gt;Clas Ohlson&lt;/td&gt;&lt;td&gt;Kingston 16 GB SD card&lt;/td&gt;&lt;td&gt;199.-&lt;/td&gt;&lt;/tr&gt;
-&lt;tr&gt;&lt;td&gt;Total cost&lt;/td&gt;&lt;td&gt;&lt;/td&gt;&lt;td&gt;943.80&lt;/td&gt;&lt;/tr&gt;
-
-&lt;/table&gt;&lt;/p&gt;
-
-&lt;p&gt;Now my mesh network at home consist of one laptop in the basement
-connected to my production network, one Raspberry Pi node on the 1th
-floor that can be seen by my neighbor across the park, and one
-play-node I use to develop the image building script.  And some times
-I hook up my work horse laptop to the mesh to test it.  I look forward
-to figuring out what kind of latency the batman-adv setup will give,
-and how much packet loss we will experience around the park. :)&lt;/p&gt;
