Immediately after installation a school +server running all services needed for a school network is set up just +waiting for users and machines being added via GOsa², a comfortable +Web-UI. A netbooting environment is prepared using PXE, so after +initial installation of the main server from CD or USB stick all other +machines can be installed via the network. The provided school server +provides LDAP database and Kerberos authentication service, +centralized home directories, DHCP server, web proxy and many other +services. The desktop contains more than 60 educational software +packages[3] and more are available from the Debian archive, and +schools can choose between KDE, Gnome, LXDE, Xfce and MATE desktop +environment. + + [2] &lt;URL: <a href="http://www.skolelinux.org/">http://www.skolelinux.org/</a> &gt; + [3] &lt;URL: <a href="http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html">http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html</a> &gt; + +Full release notes and manual +============================= + +Below the download URLs there is a list of some of the new features +and bugfixes of Debian Edu 8.0+edu0~alpha0 Codename Jessie.

I had volunteered on behalf of the +Norwegian Unix Users Group (NUUG) to video record the talks, and we +had a great and exhausting time recording the entire day, two days in +a row. There were only two of us, Hans-Petter and me, and we used the +regular video equipment for NUUG, with a +<a href="http://dvswitch.alioth.debian.org/wiki/">dvswitch</a>, a +camera and a VGA to DV convert box, and mixed video and slides +live.</p> + +<p>Hans-Petter did the post-processing, consisting of uploading the +around 180 GiB of raw video to Youtube, and the result is +<a href="https://www.youtube.com/user/MakerConNordic/">now becoming +public</a> on the MakerConNordic account.

First you visit one web page, enter the moderation password +and get a new page shown with a list of all the messages to moderate +and various options for each email address. This take a while for +every list you moderate, and you need to do it regularly to do a good +job as a list moderator. But there is a quick alternative, +<a href="http://heim.ifi.uio.no/kjetilho/hacks/#listadmin">the +listadmin program</a>. It allow you to check lists for new messages +to moderate in a fraction of a second. Here is a test run on two +lists I recently took over:</p> + +<p><blockquote><pre> +% time listadmin xiph +fetching data for pkg-xiph-commits@lists.alioth.debian.org ... nothing in queue +fetching data for pkg-xiph-maint@lists.alioth.debian.org ... nothing in queue + +real 0m1.709s +user 0m0.232s +sys 0m0.012s +% +</pre></blockquote></p> + +<p>In 1.7 seconds I had checked two mailing lists and confirmed that +there are no message in the moderation queue. Every morning I +currently moderate 68 mailman lists, and it normally take around two +minutes. When I took over the two pkg-xiph lists above a few days +ago, there were 400 emails waiting in the moderator queue. It took me +less than 15 minutes to process them all using the listadmin +program.</p> + +<p>If you install +<a href="https://tracker.debian.org/pkg/listadmin">the listadmin +package</a> from Debian and create a file <tt>~/.listadmin.ini</tt> +with content like this, the moderation task is a breeze:</p> + +<p><blockquote><pre> +username username@example.org +spamlevel 23 +default discard +discard_if_reason "Posting restricted to members only. Remove us from your mail list." + +password secret +adminurl https://{domain}/mailman/admindb/{list} +mailman-list@lists.example.com + +password hidden +other-list@otherserver.example.org +</pre></blockquote></p> + +<p>There are other options to set as well. Check the manual page to +learn the details.</p> + +<p>If you are forced to moderate lists on a mailman installation where +the SSL certificate is self signed or not properly signed by a +generally accepted signing authority, you can set a environment +variable when calling listadmin to disable SSL verification:</p> + +<p><blockquote><pre> +PERL_LWP_SSL_VERIFY_HOSTNAME=0 listadmin +</pre></blockquote></p> + +<p>If you want to moderate a subset of the lists you take care of, you +can provide an argument to the listadmin script like I do in the +initial screen dump (the xiph argument). Using an argument, only +lists matching the argument string will be processed. This make it +quick to accept messages if you notice the moderation request in your +email.</p> + +<p>Without the listadmin program, I would never be the moderator of 68 +mailing lists, as I simply do not have time to spend on that if the +process was any slower. The listadmin program have saved me hours of +time I could spend elsewhere over the years. It truly is nice free +software.</p> + +<p>As usual, if you use Bitcoin and want to show your support of my +activities, please send Bitcoin donations to my address +<b><a href="bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&label=PetterReinholdtsenBlog">15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b</a></b>.</p> + +<p>Update 2014-10-27: Added missing 'username' statement in +configuration example.
