-      <div class="date"> 9th April 2014</div>
-      <div class="body"><p>For a while now, I have been looking for a sensible offsite backup
-solution for use at home.  My requirements are simple, it must be
-cheap and locally encrypted (in other words, I keep the encryption
-keys, the storage provider do not have access to my private files).
-One idea me and my friends had many years ago, before the cloud
-storage providers showed up, was to use Google mail as storage,
-writing a Linux block device storing blocks as emails in the mail
-service provided by Google, and thus get heaps of free space.  On top
-of this one can add encryption, RAID and volume management to have
-lots of (fairly slow, I admit that) cheap and encrypted storage.  But
-I never found time to implement such system.  But the last few weeks I
-have looked at a system called
-<a href="https://bitbucket.org/nikratio/s3ql/">S3QL</a>, a locally
-mounted network backed file system with the features I need.</p>
-
-<p>S3QL is a fuse file system with a local cache and cloud storage,
-handling several different storage providers, any with Amazon S3,
-Google Drive or OpenStack API.  There are heaps of such storage
-providers.  S3QL can also use a local directory as storage, which
-combined with sshfs allow for file storage on any ssh server.  S3QL
-include support for encryption, compression, de-duplication, snapshots
-and immutable file systems, allowing me to mount the remote storage as
-a local mount point, look at and use the files as if they were local,
-while the content is stored in the cloud as well.  This allow me to
-have a backup that should survive fire.  The file system can not be
-shared between several machines at the same time, as only one can
-mount it at the time, but any machine with the encryption key and
-access to the storage service can mount it if it is unmounted.</p>
-
-<p>It is simple to use.  I'm using it on Debian Wheezy, where the
-package is included already.  So to get started, run <tt>apt-get
-install s3ql</tt>.  Next, pick a storage provider.  I ended up picking
-Greenqloud, after reading their nice recipe on
-<a href="https://greenqloud.zendesk.com/entries/44611757-How-To-Use-S3QL-to-mount-a-StorageQloud-bucket-on-Debian-Wheezy">how
-to use S3QL with their Amazon S3 service</a>, because I trust the laws
-in Iceland more than those in USA when it come to keeping my personal
-data safe and private, and thus would rather spend money on a company
-in Iceland.  Another nice recipe is available from the article
-<a href="http://www.admin-magazine.com/HPC/Articles/HPC-Cloud-Storage">S3QL
-Filesystem for HPC Storage</a> by Jeff Layton in the HPC section of
-Admin magazine.  When the provider is picked, figure out how to get
-the API key needed to connect to the storage API.  With Greencloud,
-the key did not show up until I had added payment details to my
-account.</p>
-
-<p>Armed with the API access details, it is time to create the file
-system.  First, create a new bucket in the cloud.  This bucket is the
-file system storage area.  I picked a bucket name reflecting the
-machine that was going to store data there, but any name will do.
-I'll refer to it as <tt>bucket-name</tt> below.  In addition, one need
-the API login and password, and a locally created password.  Store it
-all in ~root/.s3ql/authinfo2 like this:
-
-<p><blockquote><pre>
-[s3c]
-storage-url: s3c://s.greenqloud.com:443/bucket-name
-backend-login: API-login
-backend-password: API-password
-fs-passphrase: local-password
-</pre></blockquote></p>
-
-<p>I create my local passphrase using <tt>pwget 50</tt> or similar,
-but any sensible way to create a fairly random password should do it.
-Armed with these details, it is now time to run mkfs, entering the API
-details and password to create it:</p>
-
-<p><blockquote><pre>
-# mkdir -m 700 /var/lib/s3ql-cache
-# mkfs.s3ql --cachedir /var/lib/s3ql-cache --authfile /root/.s3ql/authinfo2 \
-  --ssl s3c://s.greenqloud.com:443/bucket-name
-Enter backend login: 
-Enter backend password: 
-Before using S3QL, make sure to read the user's guide, especially
-the 'Important Rules to Avoid Loosing Data' section.
-Enter encryption password: 
-Confirm encryption password:

-# </pre></blockquote></p>
-
-<p>The next step is mounting the file system to make the storage available.
-
-<p><blockquote><pre>
-# mount.s3ql --cachedir /var/lib/s3ql-cache --authfile /root/.s3ql/authinfo2 \
-  --ssl --allow-root s3c://s.greenqloud.com:443/bucket-name /s3ql

-s3c://s.greenqloud.com:443/bucket-name  1.0T     0  1.0T   0% /s3ql
-#
-</pre></blockquote></p>
-
-<p>The file system is now ready for use.  I use rsync to store my
-backups in it, and as the metadata used by rsync is downloaded at
-mount time, no network traffic (and storage cost) is triggered by
-running rsync.  To unmount, one should not use the normal umount
-command, as this will not flush the cache to the cloud storage, but
-instead running the umount.s3ql command like this:
-
-<p><blockquote><pre>
-# umount.s3ql /s3ql
-# 
-</pre></blockquote></p>
-
-<p>There is a fsck command available to check the file system and
-correct any problems detected.  This can be used if the local server
-crashes while the file system is mounted, to reset the "already
-mounted" flag.  This is what it look like when processing a working
-file system:</p>

+      <div class="body"><p>Rundt omkring i Oslo og Østlandsområdet henger det bokser over
+veiene som jeg har lurt på hva gjør.  De har ut fra plassering og
+vinkling sett ut som bokser som sniffer ut et eller annet fra
+forbipasserende trafikk, men det har vært uklart for meg hva det er de
+leser av.  Her om dagen tok jeg bilde av en slik boks som henger under
+<a href="http://www.openstreetmap.no/?zoom=19&mlat=59.96396&mlon=10.34443&layers=B00000">ei

+
+<p>Boksen er tydelig merket «Kapsch >>>», logoen til
+<a href="http://www.kapsch.net/">det sveitsiske selskapet Kapsch</a> som
+blant annet lager sensorsystemer for veitrafikk.  Men de lager mye
+forskjellig, og jeg kjente ikke igjen boksen på utseendet etter en
+kjapp titt på produktlista til selskapet.</p>
+
+<p>I og med at boksen henger over veien E16, en riksvei vedlikeholdt
+av Statens Vegvesen, så antok jeg at det burde være mulig å bruke

+
+<p>Av disse ser ID 775 og 862 mest relevant ut.  ID 775 antar jeg
+refererer til fotoboksen som står like ved brua, mens
+«Reisetidsregistreringspunkt» kanskje kan være boksen som henger der.
+Hvordan finner jeg så ut hva dette kan være for noe.  En titt på
+<a href="http://labs.vegdata.no/nvdb-datakatalog/862-Reisetidsregistreringspunkt/">datakatalogsiden
+for ID 862/Reisetidsregistreringspunkt</a> viser at det er finnes 53
+slike målere i Norge, og hvor de er plassert, men gir ellers få
+detaljer.  Det er plassert 40 på østlandet og 13 i Trondheimsregionen.
+Men siden nevner «AutoPASS», og hvis en slår opp oppføringen på
+Sollihøgda nevner den «Ciber AS» som ID for eksternt system.  (Kan det
+være snakk om
+<a href="http://www.proff.no/selskap/ciber-norge-as/oslo/internettdesign-og-programmering/Z0I3KMF4/">Ciber
+Norge AS</a>, et selskap eid av Ciber Europe Bv?)  Et nettsøk på
+ «Ciber AS autopass» fører meg til en artikkel fra NRK Trøndelag i
+ 2013 med tittel
+«<a href="http://www.nrk.no/trondelag/sjekk-dette-hvis-du-vil-unnga-ko-1.11327947">Sjekk
+dette hvis du vil unngå kø</a>».  Artikkelen henviser til vegvesenets
+nettside
+<a href="http://www.reisetider.no/reisetid/forside.html">reisetider.no</a>
+som har en
+<a href="http://www.reisetider.no/reisetid/omrade.html?omrade=5">kartside
+for Østlandet</a> som viser at det måles mellom Sandvika og Sollihøgda.
+Det kan dermed se ut til at jeg har funnet ut hva boksene gjør.</p>
+
+<p>Hvis det stemmer, så er dette bokser som leser av AutoPASS-ID-en
+til alle passerende biler med AutoPASS-brikke, og dermed gjør det mulig
+for de som kontrollerer boksene å holde rede på hvor en gitt bil er
+når den passerte et slikt målepunkt.  NRK-artikkelen forteller at
+denne informasjonen i dag kun brukes til å koble to
+AutoPASS-brikkepasseringer passeringer sammen for å beregne
+reisetiden, og at bruken er godkjent av Datatilsynet.  Det er desverre
+ikke mulig for en sjåfør som passerer under en slik boks å kontrollere
+at AutoPASS-ID-en kun brukes til dette i dag og i fremtiden.</p>
+
+<p>I tillegg til denne type AutoPASS-sniffere vet jeg at det også
+finnes mange automatiske stasjoner som tar betalt pr. passering (aka
+bomstasjoner), og der lagres informasjon om tid, sted og bilnummer i
+10 år.  Finnes det andre slike sniffere plassert ut på veiene?</p>
+
+<p>Personlig har jeg valgt å ikke bruke AutoPASS-brikke, for å gjøre
+det vanskeligere og mer kostbart for de som vil invadere privatsfæren
+og holde rede på hvor bilen min beveger seg til enhver tid.  Jeg håper
+flere vil gjøre det samme, selv om det gir litt høyere private
+utgifter (dyrere bompassering).  Vern om privatsfæren koster i disse
+dager.</p>

+      <div class="date">16th September 2014</div>
+      <div class="body"><p>The <a href="https://www.debian.org/">Debian</a> installer could be
+a lot quicker.  When we install more than 2000 packages in
+<a href="http://www.skolelinux.org/">Skolelinux / Debian Edu</a> using
+tasksel in the installer, unpacking the binary packages take forever.
+A part of the slow I/O issue was discussed in
+<a href="https://bugs.debian.org/613428">bug #613428</a> about too
+much file system sync-ing done by dpkg, which is the package
+responsible for unpacking the binary packages.  Other parts (like code
+executed by postinst scripts) might also sync to disk during
+installation.  All this sync-ing to disk do not really make sense to
+me.  If the machine crash half-way through, I start over, I do not try
+to salvage the half installed system.  So the failure sync-ing is
+supposed to protect against, hardware or system crash, is not really
+relevant while the installer is running.</p>
+
+<p>A few days ago, I thought of a way to get rid of all the file
+system sync()-ing in a fairly non-intrusive way, without the need to
+change the code in several packages.  The idea is not new, but I have
+not heard anyone propose the approach using dpkg-divert before.  It
+depend on the small and clever package
+<a href="https://packages.qa.debian.org/eatmydata">eatmydata</a>, which
+uses LD_PRELOAD to replace the system functions for syncing data to
+disk with functions doing nothing, thus allowing programs to live
+dangerous while speeding up disk I/O significantly.  Instead of
+modifying the implementation of dpkg, apt and tasksel (which are the
+packages responsible for selecting, fetching and installing packages),
+it occurred to me that we could just divert the programs away, replace
+them with a simple shell wrapper calling
+"eatmydata&nbsp;$program&nbsp;$@", to get the same effect.
+Two days ago I decided to test the idea, and wrapped up a simple
+implementation for the Debian Edu udeb.</p>
+
+<p>The effect was stunning.  In my first test it reduced the running
+time of the pkgsel step (installing tasks) from 64 to less than 44
+minutes (20 minutes shaved off the installation) on an old Dell
+Latitude D505 machine.  I am not quite sure what the optimised time
+would have been, as I messed up the testing a bit, causing the debconf
+priority to get low enough for two questions to pop up during
+installation.  As soon as I saw the questions I moved the installation
+along, but do not know how long the question were holding up the
+installation.  I did some more measurements using Debian Edu Jessie,
+and got these results.  The time measured is the time stamp in
+/var/log/syslog between the "pkgsel: starting tasksel" and the
+"pkgsel: finishing up" lines, if you want to do the same measurement
+yourself.  In Debian Edu, the tasksel dialog do not show up, and the
+timing thus do not depend on how quickly the user handle the tasksel
+dialog.</p>

+<p>The test is done using a netinst ISO on a USB stick, so some of the
+time is spent downloading packages.  The connection to the Internet
+was 100Mbit/s during testing, so downloading should not be a
+significant factor in the measurement.  Download typically took a few
+seconds to a few minutes, depending on the amount of packages being
+installed.</p>
+
+<p>The speedup is implemented by using two hooks in
+<a href="https://www.debian.org/devel/debian-installer/">Debian
+Installer</a>, the pre-pkgsel.d hook to set up the diverts, and the
+finish-install.d hook to remove the divert at the end of the
+installation.  I picked the pre-pkgsel.d hook instead of the
+post-base-installer.d hook because I test using an ISO without the
+eatmydata package included, and the post-base-installer.d hook in
+Debian Edu can only operate on packages included in the ISO.  The
+negative effect of this is that I am unable to activate this
+optimization for the kernel installation step in d-i.  If the code is
+moved to the post-base-installer.d hook, the speedup would be larger
+for the entire installation.</p>
+
+<p>I've implemented this in the
+<a href="https://packages.qa.debian.org/debian-edu-install">debian-edu-install</a>
+git repository, and plan to provide the optimization as part of the
+Debian Edu installation.  If you want to test this yourself, you can
+create two files in the installer (or in an udeb).  One shell script
+need do go into /usr/lib/pre-pkgsel.d/, with content like this:</p>

-<p>Thanks to the cache, working on files that fit in the cache is very
-quick, about the same speed as local file access.  Uploading large
-amount of data is to me limited by the bandwidth out of and into my
-house.  Uploading 685 MiB with a 100 MiB cache gave me 305 kiB/s,
-which is very close to my upload speed, and downloading the same
-Debian installation ISO gave me 610 kiB/s, close to my download speed.
-Both were measured using <tt>dd</tt>.  So for me, the bottleneck is my
-network, not the file system code.  I do not know what a good cache
-size would be, but suspect that the cache should e larger than your
-working set.</p>
-
-<p>I mentioned that only one machine can mount the file system at the
-time.  If another machine try, it is told that the file system is
-busy:</p>
+<p>To clean up, another shell script should go into
+/usr/lib/finish-install.d/ with code like this:
 
 <p><blockquote><pre>
-# mount.s3ql --cachedir /var/lib/s3ql-cache --authfile /root/.s3ql/authinfo2 \
-  --ssl --allow-root s3c://s.greenqloud.com:443/bucket-name /s3ql
-Using 8 upload threads.
-Backend reports that fs is still mounted elsewhere, aborting.

 </pre></blockquote></p>
 
-<p>The file content is uploaded when the cache is full, while the
-metadata is uploaded once every 24 hour by default.  To ensure the
-file system content is flushed to the cloud, one can either umount the
-file system, or ask S3QL to flush the cache and metadata using
-s3qlctrl:
+<p>In Debian Edu, I placed both code fragments in a separate script
+edu-eatmydata-install and call it from the pre-pkgsel.d and
+finish-install.d scripts.</p>
+
+<p>By now you might ask if this change should get into the normal
+Debian installer too?  I suspect it should, but am not sure the
+current debian-installer coordinators find it useful enough.  It also
+depend on the side effects of the change.  I'm not aware of any, but I
+guess we will see if the change is safe after some more testing.
+Perhaps there is some package in Debian depending on sync() and
+fsync() having effect?  Perhaps it should go into its own udeb, to
+allow those of us wanting to enable it to do so without affecting
+everyone.</p>
+
+<p>Update 2014-09-24: Since a few days ago, enabling this optimization
+will break installation of all programs using gnutls because of
+<a href="https://bugs.debian.org/702711">bug #702711.  An updated
+eatmydata package in Debian will solve it.</p>

+      <div class="date">10th September 2014</div>
+      <div class="body"><p>Yesterday, I had the pleasure of attending a talk with the
+<a href="http://www.nuug.no/">Norwegian Unix User Group</a> about
+<a href="http://www.nuug.no/aktiviteter/20140909-sks-keyservers/">the
+OpenPGP keyserver pool sks-keyservers.net</a>, and was very happy to
+learn that there is a large set of publicly available key servers to
+use when looking for peoples public key.  So far I have used
+subkeys.pgp.net, and some times wwwkeys.nl.pgp.net when the former
+were misbehaving, but those days are ended.  The servers I have used
+up until yesterday have been slow and some times unavailable.  I hope
+those problems are gone now.</p>
+
+<p>Behind the round robin DNS entry of the
+<a href="https://sks-keyservers.net/">sks-keyservers.net</a> service
+there is a pool of more than 100 keyservers which are checked every
+day to ensure they are well connected and up to date.  It must be
+better than what I have used so far. :)</p>
+
+<p>Yesterdays speaker told me that the service is the default
+keyserver provided by the default configuration in GnuPG, but this do
+not seem to be used in Debian.  Perhaps it should?</p>
+
+<p>Anyway, I've updated my ~/.gnupg/options file to now include this
+line:</p>
 
 <p><blockquote><pre>
-# s3qlctrl upload-meta /s3ql
-# s3qlctrl flushcache /s3ql
-# 
+keyserver pool.sks-keyservers.net
 </pre></blockquote></p>
 
-<p>If you are curious about how much space your data uses in the
-cloud, and how much compression and deduplication cut down on the
-storage usage, you can use s3qlstat on the mounted file system to get
-a report:</p>
+<p>With GnuPG version 2 one can also locate the keyserver using SRV
+entries in DNS.  Just for fun, I did just that at work, so now every
+user of GnuPG at the University of Oslo should find a OpenGPG
+keyserver automatically should their need it:</p>
 
 <p><blockquote><pre>
-# s3qlstat /s3ql
-Directory entries:    9141
-Inodes:               9143
-Data blocks:          8851
-Total data size:      22049.38 MB
-After de-duplication: 21955.46 MB (99.57% of total)
-After compression:    21877.28 MB (99.22% of total, 99.64% of de-duplicated)
-Database size:        2.39 MB (uncompressed)
-(some values do not take into account not-yet-uploaded dirty blocks in cache)
-#

+_pgpkey-http._tcp.uio.no has SRV record 0 100 11371 pool.sks-keyservers.net.

-<p>I mentioned earlier that there are several possible suppliers of
-storage.  I did not try to locate them all, but am aware of at least
-<a href="https://www.greenqloud.com/">Greenqloud</a>,
-<a href="http://drive.google.com/">Google Drive</a>,
-<a href="http://aws.amazon.com/s3/">Amazon S3 web serivces</a>,
-<a href="http://www.rackspace.com/">Rackspace</a> and
-<a href="http://crowncloud.net/">Crowncloud</A>.  The latter even
-accept payment in Bitcoin.  Pick one that suit your need.  Some of
-them provide several GiB of free storage, but the prize models are
-quire different and you will have to figure out what suit you
-best.</p>
-
-<p>While researching this blog post, I had a look at research papers
-and posters discussing the S3QL file system.  There are several, which
-told me that the file system is getting a critical check by the
-science community and increased my confidence in using it.  One nice
-poster is titled
-"<a href="http://www.lanl.gov/orgs/adtsc/publications/science_highlights_2013/docs/pg68_69.pdf">An
-Innovative Parallel Cloud Storage System using OpenStack’s SwiftObject
-Store and Transformative Parallel I/O Approach</a>" by Hsing-Bung
-Chen, Benjamin McClelland, David Sherrill, Alfred Torrez, Parks Fields
-and Pamela Smith.  Please  have a look.</p>
-
-<p>Given my problems with different file systems earlier, I decided to
-check out the mounted S3QL file system to see if it would be usable as
-a home directory (in other word, that it provided POSIX semantics when
-it come to locking and umask handling etc).  Running
-<a href="http://people.skolelinux.org/pere/blog/Testing_if_a_file_system_can_be_used_for_home_directories___.html">my
-test code to check file system semantics</a>, I was happy to discover that
-no error was found.  So the file system can be used for home
-directories, if one chooses to do so.</p>
-
-<p>If you do not want a locally file system, and want something that
-work without the Linux fuse file system, I would like to mention the
-<a href="http://www.tarsnap.com/">Tarsnap service</a>, which also
-provide locally encrypted backup using a command line client.  It have
-a nicer access control system, where one can split out read and write
-access, allowing some systems to write to the backup and others to
-only read from it.</p>

-activities, please send Bitcoin donations to my address

+<p>Now if only
+<a href="http://ietfreport.isoc.org/idref/draft-shaw-openpgp-hkp/">the
+HKP lookup protocol</a> supported finding signature paths, I would be
+very happy.  It can look up a given key or search for a user ID, but I
+normally do not want that, but to find a trust path from my key to
+another key.  Given a user ID or key ID, I would like to find (and
+download) the keys representing a signature path from my key to the
+key in question, to be able to get a trust path between the two keys.
+This is as far as I can tell not possible today.  Perhaps something
+for a future version of the protocol?</p>

-      <div class="date"> 1st April 2014</div>
-      <div class="body"><p>Microsoft have announced that Windows XP reaches its end of life
-2014-04-08, in 7 days.  But there are heaps of machines still running
-Windows XP, and depending on Windows XP to run their applications, and
-upgrading will be expensive, both when it comes to money and when it
-comes to the amount of effort needed to migrate from Windows XP to a
-new operating system.  Some obvious options (buy new a Windows
-machine, buy a MacOSX machine, install Linux on the existing machine)
-are already well known and covered elsewhere.  Most of them involve
-leaving the user applications installed on Windows XP behind and
-trying out replacements or updated versions. In this blog post I want
-to mention one strange bird that allow people to keep the hardware and
-the existing Windows XP applications and run them on a free software
-operating system that is Windows XP compatible.</p>
-
-<p><a href="http://www.reactos.org/">ReactOS</a> is a free software
-operating system (GNU GPL licensed) working on providing a operating
-system that is binary compatible with Windows, able to run windows
-programs directly and to use Windows drivers for hardware directly.
-The project goal is for Windows user to keep their existing machines,
-drivers and software, and gain the advantages from user a operating
-system without usage limitations caused by non-free licensing.  It is
-a Windows clone running directly on the hardware, so quite different
-from the approach taken by <a href="http://www.winehq.org/">the Wine
-project</a>, which make it possible to run Windows binaries on
-Linux.</p>
-
-<p>The ReactOS project share code with the Wine project, so most
-shared libraries available on Windows are already implemented already.
-There is also a software manager like the one we are used to on Linux,
-allowing the user to install free software applications with a simple
-click directly from the Internet.  Check out the
-<a href="http://www.reactos.org/screenshots">screen shots on the
-project web site</a> for an idea what it look like (it looks just like
-Windows before metro).</p>
-
-<p>I do not use ReactOS myself, preferring Linux and Unix like
-operating systems.  I've tested it, and it work fine in a virt-manager
-virtual machine.  The browser, minesweeper, notepad etc is working
-fine as far as I can tell.  Unfortunately, my main test application
-is the software included on a CD with the Lego Mindstorms NXT, which
-seem to install just fine from CD but fail to leave any binaries on
-the disk after the installation.  So no luck with that test software.
-No idea why, but hope someone else figure out and fix the problem.
-I've tried the ReactOS Live ISO on a physical machine, and it seemed
-to work just fine.  If you like Windows and want to keep running your
-old Windows binaries, check it out by
-<a href="http://www.reactos.org/download">downloading</a> the
-installation CD, the live CD or the preinstalled virtual machine
-image.</p>

+      <div class="body"><p>The complete and free “out of the box” software solution for
+schools, <a href="http://www.skolelinux.org/">Debian Edu /
+Skolelinux</a>, is used quite a lot in Germany, and one of the people
+involved is Bernd Zeitzen, who show up on the project mailing lists
+from time to time with interesting questions and tips on how to adjust
+the setup.  I managed to interview him this summer.</p>
 
 <p><strong>Who are you, and how do you spend your days?</strong></p>
 
-<p>My name is Roger Marsal, I'm 27 years old (1986 generation) and I
-live in Barcelona, Spain. I've got a strong business background and I
-work as a patrimony manager and as a real estate agent.  Additionally,
-I've co-founded a British based tech company that is nowadays on the
-last development phase of a new social networking concept.</p>
-
-<p>I'm a Linux enthusiast that started its journey with Ubuntu four years
-ago and have recently switched to Debian seeking rock solid stability
-and as a necessary step to gain expertise.</p>
-
-<p>In a nutshell, I spend my days working and learning as much as I
-can to face both my job, entrepreneur project and feed my Linux
-hunger.</p>
+<p>My name is Bernd Zeitzen and I'm married with Hedda, a self
+employed physiotherapist.  My former profession is tool maker, but I
+haven't worked for 30 years in this job.  30 years ago I started to
+support my wife and become her officeworker and a few years later the
+administrator for a small computer network, today based on Ubuntu
+Server (Samba, OpenVPN). For her daily work she has to use Windows
+Desktops because the software she needs to organize her business only
+works with Windows . :-(</p>
+
+<p>In 1988 we started with one PC and DOS, then I learned to use
+Windows 98, 2000, XP, …, 8, Ubuntu, MacOSX.  Today we are running a
+Linux server with 6 Windows clients and 10 persons (teacher of
+children with special needs, speech therapist, occupational therapist,
+psychologist and officeworkers) using our Samba shares via OpenVPN to
+work with the documentations of our patients.</p>
 
 <p><strong>How did you get in contact with the Skolelinux / Debian Edu
 project?</strong></p>
 
-<p>I discovered the <a href="http://www.ltsp.org/">LTSP</a> advantages
-with "Ubuntu 12.04 alternate install" and after a year of use I
-started looking for an alternative.  Even though I highly value and
-respect the Ubuntu project, I thought it was necessary for me to
-change to a more robust and stable alternative.  As far as I was using
-Debian on my personal laptop I thought it would be fine to install
-Debian and configure an LTSP server myself.  Surprised, I discovered
-that the Debian project also supported a kind of Edubuntu equivalent,
-and after having some pain I obtained a Debian Edu network up and
-running.  I just loved it.</p>
+<p>Two years ago a friend of mine asked me, if I want to get a job in
+his school (<a href="http://www.gymnasium-harsewinkel.de/">Gymnasium
+Harsewinkel</a>).  They started with Skolelinux / Debian Edu and they
+were looking for people to give support to the teachers using the
+software and the network and teaching the pupils increasing their
+computer skills in optional lessons.  I'm spending 4-6 hours a week
+with this job.</p>
 
 <p><strong>What do you see as the advantages of Skolelinux / Debian
 Edu?</strong></p>
 
-<p>I found a main advantage in that, once you know "the tips and
-tricks", a new installation just works out of the box. It's the most
-complete alternative I've found to create an LTSP network. All the
-other distributions seems to be made of plastic, Debian Edu seems to
-be made of steel.</p>
+<p>The independence.</p>
 
-<p><strong>What do you see as the disadvantages of Skolelinux / Debian
-Edu?</strong></p>
+<p>First: Every person is allowed to use, share and develop the
+software. Even if you are poor, you are allowed to use the software
+included in Skolelinux/Debian Edu and all the other Free Software.</p>
 
-<p>I found two main disadvantages.</p>
+<p>Second: The software runs on old machines and this gives us the
+possibility to recycle computers, weeded out from offices.  The
+servers and desktops are running for more than two years and they are
+working reliable. </p>
 
-<p>I'm not an expert but I've got notions and I had to spent a considerable
-amount of time trying to bring up a standard network topology. I'm quite
-stubborn and I just worked until I did but I'm sure many people with few
-resources (not big schools, but academies for example) would have switched
-or dropped.</p>
+<p>We have two servers (one tjener and one terminal server), 45
+workstations in three classrooms and seven laptops as a mobile
+solution for all classrooms.  These machines are all booting from the
+terminal server.  In the moment we are installing 30 laptops as mobile
+workstations.  Then the pupils have the possibility to work with these
+machines in their classrooms.  Internet access is realized by a WLAN
+router, connected to the schools network. This is all done without a
+dedicated system administrator or a computer science teacher.</p>
 
-<p>It's amazing how such a complex system like Debian Edu has achieved
-this out-of-the-box state. Even though tweaking without breaking gets
-more difficult, as more factors have to be considered. This can
-discourage many people too.</p>
+<p><strong>What do you see as the disadvantages of Skolelinux / Debian
+Edu?</strong></p>
 
-<p><strong>Which free software do you use daily?</strong></p>
+<p>Teachers and pupils are Windows users.  &lt;Irony on&gt; And Linux
+isn't cool. It's software for freaks using the command line. &lt;Irony
+off&gt; They don't realize the stability of the system. </p>
 
-<p>I use Debian, Firefox, Okular, Inkscape, LibreOffice and
-Virtualbox.</p>
+<p><strong>Which free software do you use daily?</strong></p>
 
+<p>Firefox, Thunderbird, LibreOffice, Ubuntu Server 12.04 (Samba,
+Apache, MySQL, Joomla!, … and Skolelinux / Debian Edu)</p>
 
 <p><strong>Which strategy do you believe is the right one to use to
 get schools to use free software?</strong></p>
 
-<p>I don't think there is a need for a particular strategy. The free

+<p>In Germany we have the situation: every school is free to decide

+teachers who learned to use Windows and MS Office. They buy a PC with
+Windows preinstalled and an additional testing version of MS
+Office. They don't know about the possibility to use Free Software
+instead.  Another problem are the publisher of school books.  They
+develop their software, added to the school books, for Windows.</p>

-      <div class="body"><p>Did you ever need to store logs or other files in a way that would
-allow it to be used as evidence in court, and needed a way to
-demonstrate without reasonable doubt that the file had not been
-changed since it was created?  Or, did you ever need to document that
-a given document was received at some point in time, like some
-archived document or the answer to an exam, and not changed after it
-was received?  The problem in these settings is to remove the need to
-trust yourself and your computers, while still being able to prove
-that a file is the same as it was at some given time in the past.</p>
-
-<p>A solution to these problems is to have a trusted third party
-"stamp" the document and verify that at some given time the document
-looked a given way.  Such
-<a href="https://en.wikipedia.org/wiki/Notarius">notarius</a> service
-have been around for thousands of years, and its digital equivalent is
-called a
-<a href="http://en.wikipedia.org/wiki/Trusted_timestamping">trusted
-timestamping service</a>.  <a href="http://www.ietf.org/">The Internet
-Engineering Task Force</a> standardised how such service could work a
-few years ago as <a href="http://tools.ietf.org/html/rfc3161">RFC
-3161</a>.  The mechanism is simple.  Create a hash of the file in
-question, send it to a trusted third party which add a time stamp to
-the hash and sign the result with its private key, and send back the
-signed hash + timestamp.  Both email, FTP and HTTP can be used to
-request such signature, depending on what is provided by the service
-used. Anyone with the document and the signature can then verify that
-the document matches the signature by creating their own hash and
-checking the signature using the trusted third party public key.
-There are several commercial services around providing such
-timestamping.  A quick search for
-"<a href="https://duckduckgo.com/?q=rfc+3161+service">rfc 3161
-service</a>" pointed me to at least
-<a href="https://www.digistamp.com/technical/how-a-digital-time-stamp-works/">DigiStamp</a>,
-<a href="http://www.quovadisglobal.co.uk/CertificateServices/SigningServices/TimeStamp.aspx">Quo
-Vadis</a>,
-<a href="https://www.globalsign.com/timestamp-service/">Global Sign</a>
-and <a href="http://www.globaltrustfinder.com/TSADefault.aspx">Global
-Trust Finder</a>.  The system work as long as the private key of the
-trusted third party is not compromised.</p>
-
-<p>But as far as I can tell, there are very few public trusted
-timestamp services available for everyone.  I've been looking for one
-for a while now. But yesterday I found one over at
-<a href="https://www.pki.dfn.de/zeitstempeldienst/">Deutches
-Forschungsnetz</a> mentioned in
-<a href="http://www.d-mueller.de/blog/dealing-with-trusted-timestamps-in-php-rfc-3161/">a
-blog by David Müller</a>.  I then found
-<a href="http://www.rz.uni-greifswald.de/support/dfn-pki-zertifikate/zeitstempeldienst.html">a
-good recipe on how to use the service</a> over at the University of
-Greifswald.</p>
-
-<p><a href="http://www.openssl.org/">The OpenSSL library</a> contain
-both server and tools to use and set up your own signing service.  See
-the ts(1SSL), tsget(1SSL) manual pages for more details.  The
-following shell script demonstrate how to extract a signed timestamp
-for any file on the disk in a Debian environment:</p>
-
-<p><blockquote><pre>
-#!/bin/sh
-set -e
-url="http://zeitstempel.dfn.de"
-caurl="https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt"
-reqfile=$(mktemp -t tmp.XXXXXXXXXX.tsq)
-resfile=$(mktemp -t tmp.XXXXXXXXXX.tsr)
-cafile=chain.txt
-if [ ! -f $cafile ] ; then
-    wget -O $cafile "$caurl"
-fi
-openssl ts -query -data "$1" -cert | tee "$reqfile" \
-    | /usr/lib/ssl/misc/tsget -h "$url" -o "$resfile"
-openssl ts -reply -in "$resfile" -text 1>&2
-openssl ts -verify -data "$1" -in "$resfile" -CAfile "$cafile" 1>&2
-base64 < "$resfile"
-rm "$reqfile" "$resfile"
-</pre></blockquote></p>
-
-<p>The argument to the script is the file to timestamp, and the output
-is a base64 encoded version of the signature to STDOUT and details
-about the signature to STDERR.  Note that due to
-<a href="http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=742553">a bug
-in the tsget script</a>, you might need to modify the included script
-and remove the last line.  Or just write your own HTTP uploader using
-curl. :) Now you too can prove and verify that files have not been
-changed.</p>
-
-<p>But the Internet need more public trusted timestamp services.
-Perhaps something for <a href="http://www.uninett.no/">Uninett</a> or
-my work place the <a href="http://www.uio.no/">University of Oslo</a>

-written by Bastian Blank.  It is
-<a href="http://packages.qa.debian.org/p/python-dvdvideo.html">in Debian

-<p>So far, python-dvdvideo have failed on between 10 and

-DVD structures, as the python library
-<a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=723079">claim

+      <div class="body"><p>The <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux
+project</a> provide an instruction manual for teachers, system
+administrators and other users that contain useful tips for setting up
+and maintaining a Debian Edu installation.  This text is about how the
+text processing of this manual is handled in the project.</p>
+
+<p>One goal of the project is to provide information in the native
+language of its users, and for this we need to handle translations.
+But we also want to make sure each language contain the same
+information, so for this we need a good way to keep the translations
+in sync.  And we want it to be easy for our users to improve the
+documentation, avoiding the need to learn special formats or tools to
+contribute, and the obvious way to do this is to make it possible to
+edit the documentation using a web browser.  We also want it to be
+easy for translators to keep the translation up to date, and give them
+help in figuring out what need to be translated. Here is the list of
+tools and the process we have found trying to reach all these
+goals.</p>
+
+<p>We maintain the authoritative source of our manual in the
+<a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/">Debian
+wiki</a>, as several wiki pages written in English.  It consist of one
+front page with references to the different chapters, several pages
+for each chapter, and finally one "collection page" gluing all the
+chapters together into one large web page (aka
+<a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/AllInOne">the
+AllInOne page</a>).  The AllInOne page is the one used for further
+processing and translations.  Thanks to the fact that the
+<a href="http://moinmo.in/">MoinMoin</a> installation on
+wiki.debian.org support exporting pages in
+<a href="http://www.docbook.org/">the Docbook format</a>, we can fetch
+the list of pages to export using the raw version of the AllInOne
+page, loop over each of them to generate a Docbook XML version of the
+manual.  This process also download images and transform image
+references to use the locally downloaded images.  The generated
+Docbook XML files are slightly broken, so some post-processing is done
+using the <tt>documentation/scripts/get_manual</tt> program, and the
+result is a nice Docbook XML file (debian-edu-wheezy-manual.xml) and
+a handfull of images.  The XML file can now be used to generate PDF, HTML
+and epub versions of the English manual.  This is the basic step of
+our process, making PDF (using dblatex), HTML (using xsltproc) and
+epub (using dbtoepub) version from Docbook XML, and the resulting files
+are placed in the debian-edu-doc-en binary package.</p>
+
+<p>But English documentation is not enough for us.  We want translated
+documentation too, and we want to make it easy for translators to
+track the English original.  For this we use the
+<a href="http://packages.qa.debian.org/p/poxml.html">poxml</a> package,
+which allow us to transform the English Docbook XML file into a
+translation file (a .pot file), usable with the normal gettext based
+translation tools used by those translating free software.  The pot
+file is used to create and maintain translation files (several .po
+files), which the translations update with the native language
+translations of all titles, paragraphs and blocks of text in the
+original.  The next step is combining the original English Docbook XML
+and the translation file (say debian-edu-wheezy-manual.nb.po), to
+create a translated Docbook XML file (in this case
+debian-edu-wheezy-manual.nb.xml).  This translated (or partly
+translated, if the translation is not complete) Docbook XML file can
+then be used like the original to create a PDF, HTML and epub version
+of the documentation.</p>
+
+<p>The translators use different tools to edit the .po files.  We
+recommend using
+<a href="http://www.kde.org/applications/development/lokalize/">lokalize</a>,
+while some use emacs and vi, others can use web based editors like
+<a href="http://pootle.translatehouse.org/">Poodle</a> or
+<a href="https://www.transifex.com/">Transifex</a>.  All we care about
+is where the .po file end up, in our git repository.  Updated
+translations can either be committed directly to git, or submitted as
+<a href="https://bugs.debian.org/src:debian-edu-doc">bug reports
+against the debian-edu-doc package</a>.</p>
+
+<p>One challenge is images, which both might need to be translated (if
+they show translated user applications), and are needed in different
+formats when creating PDF and HTML versions (epub is a HTML version in
+this regard).  For this we transform the original PNG images to the
+needed density and format during build, and have a way to provide
+translated images by storing translated versions in
+images/$LANGUAGECODE/.  I am a bit unsure about the details here.  The
+package maintainers know more.</p>
+
+<p>If you wonder what the result look like, we provide
+<a href="http://maintainer.skolelinux.org/debian-edu-doc/">the content
+of the documentation packages on the web</a>.  See for example the
+<a href="http://maintainer.skolelinux.org/debian-edu-doc/it/debian-edu-wheezy-manual.pdf">Italian
+PDF version</a> or the
+<a href="http://maintainer.skolelinux.org/debian-edu-doc/de/debian-edu-wheezy-manual.html">German
+HTML version</a>.  We do not yet build the epub version by default,
+but perhaps it will be done in the future.</p>

-      <div class="body"><p>The <a href="https://wiki.debian.org/FreedomBox">Freedombox
-project</a> is working on providing the software and hardware for
-making it easy for non-technical people to host their data and
-communication at home, and being able to communicate with their
-friends and family encrypted and away from prying eyes.  It has been
-going on for a while, and is slowly progressing towards a new test
-release (0.2).</p>
-
-<p>And what day could be better than the Pi day to announce that the
-new version will provide "hard drive" / SD card / USB stick images for
-Dreamplug, Raspberry Pi and VirtualBox (or any other virtualization
-system), and can also be installed using a Debian installer preseed
-file.  The Debian based Freedombox is now based on Debian Jessie,
-where most of the needed packages used are already present.  Only one,
-the freedombox-setup package, is missing.  To try to build your own
-boot image to test the current status, fetch the freedom-maker scripts
-and build using
-<a href="http://packages.qa.debian.org/vmdebootstrap">vmdebootstrap</a>
-with a user with sudo access to become root:
-
-<pre>
-git clone http://anonscm.debian.org/git/freedombox/freedom-maker.git \
-  freedom-maker
-sudo apt-get install git vmdebootstrap mercurial python-docutils \
-  mktorrent extlinux virtualbox qemu-user-static binfmt-support \
-  u-boot-tools
-make -C freedom-maker dreamplug-image raspberry-image virtualbox-image
-</pre>
-
-<p>Root access is needed to run debootstrap and mount loopback
-devices.  See the README for more details on the build. If you do not
-want all three images, trim the make line.  But note that thanks to <a
-href="https://bugs.debian.org/741407">a race condition in
-vmdebootstrap</a>, the build might fail without the patch to the
-kpartx call.</p>
-
-<p>If you instead want to install using a Debian CD and the preseed
-method, boot a Debian Wheezy ISO and use this boot argument to load
-the preseed values:</p>
-
-<pre>
-url=<a href="http://www.reinholdtsen.name/freedombox/preseed-jessie.dat">http://www.reinholdtsen.name/freedombox/preseed-jessie.dat</a>
-</pre>
-
-<p>But note that due to <a href="https://bugs.debian.org/740673">a
-recently introduced bug in apt in Jessie</a>, the installer will
-currently hang while setting up APT sources.  Killing the
-'<tt>apt-cdrom ident</tt>' process when it hang a few times during the
-installation will get the installation going.  This affect all
-installations in Jessie, and I expect it will be fixed soon.</p>
-
-<p>Give it a go and let us know how it goes on the mailing list, and help
-us get the new release published. :) Please join us on
-<a href="irc://irc.debian.org:6667/%23freedombox">IRC (#freedombox on

+<a href="http://people.skolelinux.org/pere/blog/Hvordan_enkelt_laste_ned_filmer_fra_NRK.html">min

+innslag er å bruke siste versjon 2014.06.07 av
+<a href="http://rg3.github.io/youtube-dl/">youtube-dl</a>.  Støtten i
+youtube-dl <a href="https://github.com/rg3/youtube-dl/issues/2980">kom
+inn for 23 dager siden</a> og
+<a href="http://packages.qa.debian.org/y/youtube-dl.html">versjonen i
+Debian</a> fungerer fint også som backport til Debian Wheezy.  Det er
+et lite problem, det håndterer kun URLer med små bokstaver, men hvis
+en har en URL med store bokstaver kan en bare gjøre alle store om til
+små bokstaver for å få youtube-dl til å laste ned.  Rapporterte
+nettopp
+<a href="https://github.com/rg3/youtube-dl/issues/2980">problemet til
+utviklerne</a>, og antar de får fikset det snart.</p>
+

-      <div class="date">12th March 2014</div>
-      <div class="body"><p>On larger sites, it is useful to use a dedicated storage server for
-storing user home directories and data.  The design for handling this
-in <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>, is
-to update the automount rules in LDAP and let the automount daemon on
-the clients take care of the rest.  I was reminded about the need to
-document this better when one of the customers of
-<a href="http://www.slxdrift.no/">Skolelinux Drift AS</a>, where I am
-on the board of directors, asked about how to do this.  The steps to
-get this working are the following:</p>
-
-<p><ol>
-
-<li>Add new storage server in DNS.  I use nas-server.intern as the
-example host here.</li>
-
-<li>Add automoun LDAP information about this server in LDAP, to allow
-all clients to automatically mount it on reqeust.</li>
-
-<li>Add the relevant entries in tjener.intern:/etc/fstab, because
-tjener.intern do not use automount to avoid mounting loops.</li>
-
-</ol></p>
-
-<p>DNS entries are added in GOsa², and not described here.  Follow the
-<a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/GettingStarted">instructions
-in the manual</a> (Machine Management with GOsa² in section Getting
-started).</p>
-
-<p>Ensure that the NFS export points on the server are exported to the
-relevant subnets or machines:</p>
-
-<p><blockquote><pre>
-root@tjener:~# showmount -e nas-server
-Export list for nas-server:
-/storage         10.0.0.0/8
-root@tjener:~#
-</pre></blockquote></p>
-
-<p>Here everything on the backbone network is granted access to the
-/storage export.  With NFSv3 it is slightly better to limit it to
-netgroup membership or single IP addresses to have some limits on the
-NFS access.</p>
-
-<p>The next step is to update LDAP.  This can not be done using GOsa²,
-because it lack a module for automount.  Instead, use ldapvi and add
-the required LDAP objects using an editor.</p>
-
-<p><blockquote><pre>
-ldapvi --ldap-conf -ZD '(cn=admin)' -b ou=automount,dc=skole,dc=skolelinux,dc=no
-</pre></blockquote></p>
-
-<p>When the editor show up, add the following LDAP objects at the
-bottom of the document.  The "/&" part in the last LDAP object is a
-wild card matching everything the nas-server exports, removing the
-need to list individual mount points in LDAP.</p>
-
-<p><blockquote><pre>
-add cn=nas-server,ou=auto.skole,ou=automount,dc=skole,dc=skolelinux,dc=no
-objectClass: automount
-cn: nas-server
-automountInformation: -fstype=autofs --timeout=60 ldap:ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
-
-add ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
-objectClass: top
-objectClass: automountMap
-ou: auto.nas-server
-
-add cn=/,ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
-objectClass: automount
-cn: /
-automountInformation: -fstype=nfs,tcp,rsize=32768,wsize=32768,rw,intr,hard,nodev,nosuid,noatime nas-server.intern:/&
-</pre></blockquote></p>
-
-<p>The last step to remember is to mount the relevant mount points in
-tjener.intern by adding them to /etc/fstab, creating the mount
-directories using mkdir and running "mount -a" to mount them.</p>
-
-<p>When this is done, your users should be able to access the files on
-the storage server directly by just visiting the
-/tjener/nas-server/storage/ directory using any application on any
-workstation, LTSP client or LTSP server.</p>
