-totalitær overvåkning på sakskartet, men også endel annet
-tankevekkende og interessant.&lt;/p&gt;

+               <description>&lt;p&gt;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
+&lt;a href=&quot;https://bitbucket.org/nikratio/s3ql/&quot;&gt;S3QL&lt;/a&gt;, a locally
+mounted network backed file system with the features I need.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;It is simple to use.  I&#39;m using it on Debian Wheezy, where the
+package is included already.  So to get started, run &lt;tt&gt;apt-get
+install s3ql&lt;/tt&gt;.  Next, pick a storage provider.  I ended up picking
+Greenqloud, after reading their nice recipe on
+&lt;a href=&quot;https://greenqloud.zendesk.com/entries/44611757-How-To-Use-S3QL-to-mount-a-StorageQloud-bucket-on-Debian-Wheezy&quot;&gt;how
+to use S3QL with their Amazon S3 service&lt;/a&gt;, 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
+&lt;a href=&quot;http://www.admin-magazine.com/HPC/Articles/HPC-Cloud-Storage&quot;&gt;S3QL
+Filesystem for HPC Storage&lt;/a&gt; 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.&lt;/p&gt;
+
+&lt;p&gt;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&#39;ll refer to it as &lt;tt&gt;bucket-name&lt;/tt&gt; below.  In addition, one need
+the API login and password, and a locally created password.  Store it
+all in ~root/.s3ql/authinfo2 like this:

-               <description>&lt;p&gt;Many years ago, I wrote a GPL licensed version of the netgroup and
-innetgr tools, because I needed them in
-&lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt;.  I called the project
-ng-utils, and it has served me well.  I placed the project under the
-&lt;a href=&quot;http://www.hungry.com/&quot;&gt;Hungry Programmer&lt;/a&gt; umbrella, and it was maintained in our CVS
-repository.  But many years ago, the CVS repository was dropped (lost,
-not migrated to new hardware, not sure), and the project have lacked a
-proper home since then.&lt;/p&gt;
-
-&lt;p&gt;Last summer, I had a look at the package and made a new release
-fixing a irritating crash bug, but was unable to store the changes in
-a proper source control system.  I applied for a project on
-&lt;a href=&quot;https://alioth.debian.org/&quot;&gt;Alioth&lt;/a&gt;, but did not have time
-to follow up on it.  Until today. :)&lt;/p&gt;
-
-&lt;p&gt;After many hours of cleaning and migration, the ng-utils project
-now have a new home, and a git repository with the highlight of the
-history of the project.  I published all release tarballs and imported
-them into the git repository.  As the project is really stable and not
-expected to gain new features any time soon, I decided to make a new
-release and call it 1.0.  Visit the new project home on
-&lt;a href=&quot;https://alioth.debian.org/projects/ng-utils/&quot;&gt;https://alioth.debian.org/projects/ng-utils/&lt;/a&gt;
-if you want to check it out.  The new version is also uploaded into
-&lt;a href=&quot;http://packages.qa.debian.org/n/ng-utils.html&quot;&gt;Debian Unstable&lt;/a&gt;.&lt;/p&gt;

-               <link>http://people.skolelinux.org/pere/blog/Testing_sysvinit_from_experimental_in_Debian_Hurd.html</link>
-               <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Testing_sysvinit_from_experimental_in_Debian_Hurd.html</guid>
-                <pubDate>Mon, 3 Feb 2014 13:40:00 +0100</pubDate>
-               <description>&lt;p&gt;A few days ago I decided to try to help the Hurd people to get
-their changes into sysvinit, to allow them to use the normal sysvinit
-boot system instead of their old one.  This follow up on the
-&lt;a href=&quot;https://teythoon.cryptobitch.de//categories/gsoc.html&quot;&gt;great
-Google Summer of Code work&lt;/a&gt; done last summer by Justus Winter to
-get Debian on Hurd working more like Debian on Linux.  To get started,
-I downloaded a prebuilt hard disk image from
-&lt;a href=&quot;http://ftp.debian-ports.org/debian-cd/hurd-i386/current/debian-hurd.img.tar.gz&quot;&gt;http://ftp.debian-ports.org/debian-cd/hurd-i386/current/debian-hurd.img.tar.gz&lt;/a&gt;,
-and started it using virt-manager.&lt;/p&gt;
-
-&lt;p&gt;The first think I had to do after logging in (root without any
-password) was to get the network operational.  I followed
-&lt;a href=&quot;https://www.debian.org/ports/hurd/hurd-install&quot;&gt;the
-instructions on the Debian GNU/Hurd ports page&lt;/a&gt; and ran these
-commands as root to get the machine to accept a IP address from the
-kvm internal DHCP server:&lt;/p&gt;
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+[s3c]
+storage-url: s3c://s.greenqloud.com:443/bucket-name
+backend-login: API-login
+backend-password: API-password
+fs-passphrase: local-password
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;I create my local passphrase using &lt;tt&gt;pwget 50&lt;/tt&gt; 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:&lt;/p&gt;

 
 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;

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

+#
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;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:
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+# umount.s3ql /s3ql
+# 

 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
 
 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
 

-&lt;p&gt;After this, the machine had internet connectivity, and I could
-upgrade it and install the sysvinit packages from experimental and
-enable it as the default boot system in Hurd.&lt;/p&gt;
+&lt;p&gt;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 &quot;already
+mounted&quot; flag.  This is what it look like when processing a working
+file system:&lt;/p&gt;

 
 

-&lt;p&gt;But before I did that, I set a password on the root user, as ssh is
-running on the machine it for ssh login to work a password need to be
-set.  Also, note that a bug somewhere in openssh on Hurd block
-compression from working.  Remember to turn that off on the client
-side.&lt;/p&gt;
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;

-&lt;p&gt;Run these commands as root to upgrade and test the new sysvinit
-stuff:&lt;/p&gt;
+&lt;p&gt;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 &lt;tt&gt;dd&lt;/tt&gt;.  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.&lt;/p&gt;
+
+&lt;p&gt;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:&lt;/p&gt;

 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
 

-&lt;p&gt;To reboot after switching boot system, you have to use
-&lt;tt&gt;reboot-hurd&lt;/tt&gt; instead of just &lt;tt&gt;reboot&lt;/tt&gt;, as there is not
-yet a sysvinit process able to receive the signals from the normal
-&#39;reboot&#39; command.  After switching to sysvinit as the boot system,
-upgrading every package and rebooting, the network come up with DHCP
-after boot as it should, and the settrans/pkill hack mentioned at the
-start is no longer needed.  But for some strange reason, there are no
-longer any login prompt in the virtual console, so I logged in using
-ssh instead.
-
-&lt;p&gt;Note that there are some race conditions in Hurd making the boot
-fail some times.  No idea what the cause is, but hope the Hurd porters
-figure it out.  At least Justus said on IRC (#debian-hurd on
-irc.debian.org) that they are aware of the problem.  A way to reduce
-the impact is to upgrade to the Hurd packages built by Justus by
-adding this repository to the machine:&lt;/p&gt;
+&lt;p&gt;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:

 
 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
 
 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;

-cat &gt; /etc/apt/sources.list.d/hurd-ci.list &amp;lt;&amp;lt;EOF
-deb http://darnassus.sceen.net/~teythoon/hurd-ci/ sid main
-EOF
+# s3qlctrl upload-meta /s3ql
+# s3qlctrl flushcache /s3ql
+# 

 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
 
 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
 

-&lt;p&gt;At the moment the prebuilt virtual machine get some packages from
-http://ftp.debian-ports.org/debian, because some of the packages in
-unstable do not yet include the required patches that are lingering in
-BTS.  This is the completely list of &quot;unofficial&quot; packages installed:&lt;/p&gt;
+&lt;p&gt;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:&lt;/p&gt;

-               <description>&lt;p&gt;Bitcoin is a incredible use of peer to peer communication and
-encryption, allowing direct and immediate money transfer without any
-central control.  It is sometimes claimed to be ideal for illegal
-activity, which I believe is quite a long way from the truth.  At least
-I would not conduct illegal money transfers using a system where the
-details of every transaction are kept forever.  This point is
-investigated in
-&lt;a href=&quot;https://www.usenix.org/publications/login&quot;&gt;USENIX ;login:&lt;/a&gt;
-from December 2013, in the article
-&quot;&lt;a href=&quot;https://www.usenix.org/system/files/login/articles/03_meiklejohn-online.pdf&quot;&gt;A
-Fistful of Bitcoins - Characterizing Payments Among Men with No
-Names&lt;/a&gt;&quot; by Sarah Meiklejohn, Marjori Pomarole,Grant Jordan, Kirill
-Levchenko, Damon McCoy, Geoffrey M. Voelker, and Stefan Savage.  They
-analyse the transaction log in the Bitcoin system, using it to find
-addresses belong to individuals and organisations and follow the flow
-of money from both Bitcoin theft and trades on Silk Road to where the
-money end up.  This is how they wrap up their article:&lt;/p&gt;
-
-&lt;p&gt;&lt;blockquote&gt;
-&lt;p&gt;&quot;To demonstrate the usefulness of this type of analysis, we turned
-our attention to criminal activity. In the Bitcoin economy, criminal
-activity can appear in a number of forms, such as dealing drugs on
-Silk Road or simply stealing someone else’s bitcoins. We followed the
-flow of bitcoins out of Silk Road (in particular, from one notorious
-address) and from a number of highly publicized thefts to see whether
-we could track the bitcoins to known services. Although some of the
-thieves attempted to use sophisticated mixing techniques (or possibly
-mix services) to obscure the flow of bitcoins, for the most part
-tracking the bitcoins was quite straightforward, and we ultimately saw
-large quantities of bitcoins flow to a variety of exchanges directly
-from the point of theft (or the withdrawal from Silk Road).&lt;/p&gt;
-
-&lt;p&gt;As acknowledged above, following stolen bitcoins to the point at
-which they are deposited into an exchange does not in itself identify
-the thief; however, it does enable further de-anonymization in the
-case in which certain agencies can determine (through, for example,
-subpoena power) the real-world owner of the account into which the
-stolen bitcoins were deposited.  Because such exchanges seem to serve
-as chokepoints into and out of the Bitcoin economy (i.e., there are
-few alternative ways to cash out), we conclude that using Bitcoin for
-money laundering or other illicit purposes does not (at least at
-present) seem to be particularly attractive.&quot;&lt;/p&gt;
-&lt;/blockquote&gt;&lt;p&gt;
-
-&lt;p&gt;These researches are not the first to analyse the Bitcoin
-transaction log.  The 2011 paper
-&quot;&lt;a href=&quot;http://arxiv.org/abs/1107.4524&quot;&gt;An Analysis of Anonymity in
-the Bitcoin System&lt;/A&gt;&quot; by Fergal Reid and Martin Harrigan is
-summarized like this:&lt;/p&gt;
-
-&lt;p&gt;&lt;blockquote&gt;
-&quot;Anonymity in Bitcoin, a peer-to-peer electronic currency system, is a
-complicated issue. Within the system, users are identified by
-public-keys only. An attacker wishing to de-anonymize its users will
-attempt to construct the one-to-many mapping between users and
-public-keys and associate information external to the system with the
-users. Bitcoin tries to prevent this attack by storing the mapping of
-a user to his or her public-keys on that user&#39;s node only and by
-allowing each user to generate as many public-keys as required. In
-this chapter we consider the topological structure of two networks
-derived from Bitcoin&#39;s public transaction history. We show that the
-two networks have a non-trivial topological structure, provide
-complementary views of the Bitcoin system and have implications for
-anonymity. We combine these structures with external information and
-techniques such as context discovery and flow analysis to investigate
-an alleged theft of Bitcoins, which, at the time of the theft, had a
-market value of approximately half a million U.S. dollars.&quot;
-&lt;/blockquote&gt;&lt;/p&gt;
-
-&lt;p&gt;I hope these references can help kill the urban myth that Bitcoin
-is anonymous.  It isn&#39;t really a good fit for illegal activites.  Use
-cash if you need to stay anonymous, at least until regular DNA
-sampling of notes and coins become the norm. :)&lt;/p&gt;
+&lt;p&gt;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
+&lt;a href=&quot;https://www.greenqloud.com/&quot;&gt;Greenqloud&lt;/a&gt;,
+&lt;a href=&quot;http://drive.google.com/&quot;&gt;Google Drive&lt;/a&gt;,
+&lt;a href=&quot;http://aws.amazon.com/s3/&quot;&gt;Amazon S3 web serivces&lt;/a&gt;,
+&lt;a href=&quot;http://www.rackspace.com/&quot;&gt;Rackspace&lt;/a&gt; and
+&lt;a href=&quot;http://crowncloud.net/&quot;&gt;Crowncloud&lt;/A&gt;.  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
+quite different and you will have to figure out what suits you
+best.&lt;/p&gt;
+
+&lt;p&gt;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
+&quot;&lt;a href=&quot;http://www.lanl.gov/orgs/adtsc/publications/science_highlights_2013/docs/pg68_69.pdf&quot;&gt;An
+Innovative Parallel Cloud Storage System using OpenStack’s SwiftObject
+Store and Transformative Parallel I/O Approach&lt;/a&gt;&quot; by Hsing-Bung
+Chen, Benjamin McClelland, David Sherrill, Alfred Torrez, Parks Fields
+and Pamela Smith.  Please  have a look.&lt;/p&gt;
+
+&lt;p&gt;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
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Testing_if_a_file_system_can_be_used_for_home_directories___.html&quot;&gt;my
+test code to check file system semantics&lt;/a&gt;, 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.&lt;/p&gt;
+
+&lt;p&gt;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
+&lt;a href=&quot;http://www.tarsnap.com/&quot;&gt;Tarsnap service&lt;/a&gt;, 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.&lt;/p&gt;

-               <description>&lt;p&gt;&lt;a href=&quot;http://www.coverity.com/&quot;&gt;Coverity&lt;/a&gt; is a nice tool to
-find problems in C, C++ and Java code using static source code
-analysis.  It can detect a lot of different problems, and is very
-useful to find memory and locking bugs in the error handling part of
-the source.  The company behind it provide
-&lt;a href=&quot;https://scan.coverity.com/&quot;&gt;check of free software projects as
-a community service&lt;/a&gt;, and many hundred free software projects are
-already checked.  A few days ago I decided to have a closer look at
-the Coverity system, and discovered that the
-&lt;a href=&quot;http://www.gnu.org/software/gnash/&quot;&gt;gnash&lt;/a&gt; and
-&lt;a href=&quot;http://sourceforge.net/projects/ipmitool/&quot;&gt;ipmitool&lt;/a&gt;
-projects I am involved with was already registered.  But these are
-fairly big, and I would also like to have a small and easy project to
-check, and decided to &lt;a href=&quot;http://scan.coverity.com/projects/1179&quot;&gt;request
-checking of the chrpath project&lt;/a&gt;.  It was
-added to the checker and discovered seven potential defects.  Six of
-these were real, mostly resource &quot;leak&quot; when the program detected an
-error.  Nothing serious, as the resources would be released a fraction
-of a second later when the program exited because of the error, but it
-is nice to do it right in case the source of the program some time in
-the future end up in a library.  Having fixed all defects and added
-&lt;a href=&quot;https://lists.alioth.debian.org/mailman/listinfo/chrpath-devel&quot;&gt;a
-mailing list for the chrpath developers&lt;/a&gt;, I decided it was time to
-publish a new release.  These are the release notes:&lt;/p&gt;

-&lt;p&gt;New in 0.16 released 2014-01-14:&lt;/p&gt;
-
-&lt;ul&gt;

-&lt;p&gt;I am a 23 year-old student from Germany who has spent half of his
-life with open source. In &quot;real life&quot;, I am, as already mentioned, a
-student in the fields of Computer Science, Electrical Engineering,
-Information Technologies and Anglistics. Due to my (only partially
-voluntary) huge engagement in the open source world, these things are
-a bit vacant right now however.&lt;/p&gt;
-
-&lt;p&gt;I also have been working as a project teacher at a Gymasnium
-(public school) for various years now. I took up that work some time
-around 2005 when still attending that school myself and have continued
-it until today. I also had been running the (kind of very advanced)
-network of that school together with a team of very interested and
-talented students in the age of 11 to 15 years, who took the chance to
-learn a lot about open source and networking before I left the school
-to help building another school&#39;s informational education concept from
-scratch.&lt;/p&gt;
-
-&lt;p&gt;That said, one might see me as a kind of &quot;glue&quot; between school kids
-and the elderly of teachers as well as between the open source
-ecosystem and the (even more complex) educational ecosystem.&lt;/p&gt;
-
-&lt;p&gt;When I am not busy with open source or education, I like Geocaching
-and cycling.&lt;/p&gt;
+&lt;li&gt;&lt;a href=&quot;http://www.aftenposten.no/nyheter/iriks/EU-domstolen-Datalagringsdirektivet-er-ulovlig-7529032.html&quot;&gt;EU-domstolen:

-&lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux / Debian Edu

-&lt;p&gt;I think that happened some time around 2009 when I first attended
-&lt;a href=&quot;http://www.froscon.org&quot;&gt;FrOSCon&lt;/a&gt; and visited the project
-booth. I think I wasn&#39;t too interested back then because I used to
-have an attitude of disliking software that does too much stuff on its
-own. Maybe I was too inexperienced to realise the upsides of an
-&quot;out-of-the-box&quot; solution ;).&lt;/p&gt;
-
-&lt;p&gt;The first time I actively talked to Skolelinux people was at
-&lt;a href=&quot;http://www.openrheinruhr.de&quot;&gt;OpenRheinRuhr&lt;/a&gt; 2011 when the
-BiscuIT project, a home-grewn software used by my school for various
-really cool things from timetables and class contact lists to lunch
-ordering, student ID card printing and project elections first got to
-a stage where it could have been published. I asked the Skolelinux
-guys running the booth if the project were interested in it and gave a
-small demonstration, but there wasn&#39;t any real feedback and the guys
-seemed rather uninterested.&lt;/p&gt;
-
-&lt;p&gt;After I left the school where I developed the software, it got
-mostly lost, but I am now reimplementing it for my new school. I have
-reusability and compatibility in mind, and I hop there will be a new
-basis for contributing it to the Skolelinux project ;)!&lt;/p&gt;
+&lt;li&gt;&lt;a href=&quot;http://www.p4.no/story.aspx?id=566431&quot;&gt;Apenes: - En
+gledens dag&lt;/a&gt; - p4.no 2014-04-08

 
 

-&lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux / Debian
-Edu?&lt;/strong&gt;&lt;/p&gt;
+&lt;li&gt;&lt;a href=&quot;http://www.nrk.no/norge/_-datalagringsdirektivet-er-ugyldig-1.11655929&quot;&gt;EU-domstolen:
+– Datalagringsdirektivet er ugyldig&lt;/a&gt; - nrk.no 2014-04-08&lt;/li&gt;

 
 

-&lt;p&gt;The most important advantage seems to be that it &quot;just
-works&quot;. After overcoming some minor (but still very annoying) glitches
-in the installer, I got a fully functional, working school network,
-without the month-long hassle I experienced when setting all that up
-from scratch in earlier years. And above that, it rocked - I didn&#39;t
-have any real hardware at hand, because the school was just founded
-and has no money whatsoever, so I installed a combined server (main
-server, terminal services and workstation) in a VM on my personal
-notebook, bridging the LTSP network interface to the ethernet port,
-and then PXE-booted the Windows notebooks that were lying around from
-it. I could use 8 clients without any performance issues, by using a
-tiny little VM on a tiny little notebook. I think that&#39;s enough to say
-that it rocks!&lt;/p&gt;
-
-&lt;p&gt;Secondly, there are marketing reasons. Life&#39;s bad, and so no
-politician will ever permit a setup described as &quot;Debian, an universal
-operating system, with some really cool educational tools&quot; while they
-will be jsut fine with &quot;Skolelinux, a single-purpose solution for your
-school network&quot;, even if both turn out to be the very same thing (yes,
-this is unfair towards the Skolelinux project, and must not be taken

 &lt;/ul&gt;
 
 &lt;/ul&gt;

-
-&lt;p&gt;I&#39;m really sorry I cannot say much more about that :(!&lt;/p&gt;
-
-&lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;
-
-&lt;p&gt;First of all, all software I use is free and open. I have abandoned
-all non-free software (except for firmware on my darned phone) this
-year.&lt;/p&gt;
-
-&lt;p&gt;I run Debian GNU/Linux on all PC systems I use. On that, I mostly
-run text tools. I use
-&lt;a href=&quot;https://www.mirbsd.org/mksh.htm&quot;&gt;mksh&lt;/a&gt; as shell,
-&lt;a href=&quot;https://www.mirbsd.org/jupp.htm&quot;&gt;jupp&lt;/a&gt; as very advanced
-text editor (I even got the developer to help me write a script/macro
-based full-featured student management software with the two),
-&lt;a href=&quot;http://mcabber.com/&quot;&gt;mcabber&lt;/a&gt; for XMPP and
-&lt;a href=&quot;http://www.irssi.org/&quot;&gt;irssi&lt;/a&gt; for IRC. For that overly
-coloured world called the WWW, I use
-&lt;a href=&quot;https://www.mozilla.org/en-US/firefox/new/&quot;&gt;Iceweasel
-(Firefox)&lt;/a&gt;. Oh, and &lt;a href=&quot;http://www.mutt.org/&quot;&gt;mutt&lt;/a&gt; for
-e-mail.&lt;/p&gt;
-
-&lt;p&gt;However, while I am personally aware of the fact that text tools
-are more efficient and powerful than anything else, I also use (or at
-least operate) some tools that are suitable to bring open source to
-kids. One of these things is &lt;a href=&quot;http://jappix.org/&quot;&gt;Jappix&lt;/a&gt;,
-which I already introduced to some kids even before they got aware of
-Facebook, making them see for themselves that they do not need
-Facebook now ;).&lt;/p&gt;
-
-&lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
-get schools to use free software?&lt;/strong&gt;&lt;/p&gt;
-
-&lt;p&gt;Well, that&#39;s a two-sided thing. One side is what I believe, and one
-side is what I have experienced.&lt;/p&gt;
-
-&lt;p&gt;I believe that the right strategy is showing them the benefits. But
-that won&#39;t work out as long as the acceptance of free alternatives
-grows globally. What I mean is that if all the kids are almost forced
-to use Windows, Facebook, Skype, you name it at home, they will not
-see why they would want to use alternatives at school. I have seen
-students take seat in front of a fully-functional, modern Debian
-desktop that could do anything their Windows at home could do, and
-they jsut refused to use it because &quot;Linux sucks&quot;. It is something
-that makes the council of our city spend around 600000 € to buy
-software - not including hardware, mind you - for operating school
-networks, and for installing a system that, as has been proved, does
-not work. For those of you readers who are good at maths, have you
-already found out how many lives could have been saved with that money
-if we had instead used it to bring education to parts of the world
-that need it? I have, and found it to be nothing less dramatic than
-plain criminal.&lt;/p&gt;
-
-&lt;p&gt;That said, the only feasible way appears to be the bottom up
-method. We have to bring free software to kids and parents. I have
-founded an association named
-&lt;a href=&quot;https://www.teckids.org&quot;&gt;Teckids&lt;/a&gt; here in Germany that does
-just that. We organise several events for kids and adolescents in the
-area of free and open source software, for example the
-&lt;a href=&quot;http://kids.froscon.org&quot;&gt;FrogLabs&lt;/a&gt;, which share staff with
-Teckids and are the youth programme of
-&lt;a href=&quot;http://www.froscon.org&quot;&gt;the Free and Open Source Software
-Conference (FrOSCon)&lt;/a&gt;. We do a lot more than most other conferences
-- this year, we first offered the FrogLabs as a holiday camp for kids
-aged 10 to 16. It was a huge success, with approx. 30 kids taking part
-and learning with and about free software through a whole weekend. All
-of us had a lot of fun, and the results were really exciting.&lt;/p&gt;
-
-&lt;p&gt;Apart from that, we are preparing a campaign that is supposed to bring
-the message of free alternatives to stuff kids use every day to them and
-their parents, e.g. the use of Jabber / Jappix instead of Facebook and
-Skype. To make that possible, we are planning to get together a team of
-clever kids who understand very well what their peers need and can bring
-it across to them. So we will have a peer-driven network of adolescents
-who teach each other and collect feedback from the community of minors.
-We then take that feedback and our own experience to work closely with
-open source projects, such as Skolelinux or Jappix, at improving their
-software in a way that makes it more and more attractive for the target
-group. At least I hope that we will have good cooperation with
-Skolelinux in the future ;)!&lt;/p&gt;
-
-&lt;p&gt;So in conclusion, what I believe is that, if it weren&#39;t for the world
-being so bad, it should be very clear to the political decision makers
-that the only way to go nowadays is free software for various reasons,
-but I have learnt that the only way that seems to work is bottom up.&lt;/p&gt;
-
-&lt;!--
-
-&gt;  * Who should be interviewed with this questions in the future?
-
-That&#39;s probably the hardest question of them all, as I do not know the
-community. However, I would be willing to do the following:
-
- &lt;li&gt;Run an interview with a German headteacher who is very open to
-   free software, and also prefers it, but cannot really use it because
-   of the decision makers above;
- &lt;li&gt;Run interviews with some kids, both with and without previous
-   knowledge about free software
-
-If that is wanted, just let me know ;).
-
---&gt;
+&lt;/p&gt;
+
+&lt;p&gt;Jeg synes det er veldig fint at nok en stemme slår fast at
+totalitær overvåkning av befolkningen er uakseptabelt, men det er
+fortsatt like viktig å beskytte privatsfæren som før, da de
+teknologiske mulighetene fortsatt finnes og utnyttes, og jeg tror
+innsats i prosjekter som
+&lt;a href=&quot;https://wiki.debian.org/FreedomBox&quot;&gt;Freedombox&lt;/a&gt; og
+&lt;a href=&quot;http://www.dugnadsnett.no/&quot;&gt;Dugnadsnett&lt;/a&gt; er viktigere enn
+noen gang.&lt;/p&gt;
+
+&lt;p&gt;&lt;strong&gt;Update 2014-04-08 12:10&lt;/strong&gt;: Kronerullingen for å
+stoppe datalagringsdirektivet i Norge gjøres hos foreningen
+&lt;a href=&quot;http://www.digitaltpersonvern.no/&quot;&gt;Digitalt Personvern&lt;/a&gt;,
+som har samlet inn 843 215,- så langt men trenger nok mye mer hvis
+
+ikke Høyre og Arbeiderpartiet bytter mening i saken.  Det var
+&lt;a href=&quot;http://www.holderdeord.no/parliament-issues/48650&quot;&gt;kun
+partinene Høyre og Arbeiderpartiet&lt;/a&gt; som stemte for
+Datalagringsdirektivet, og en av dem må bytte mening for at det skal
+bli flertall mot i Stortinget.  Se mer om saken

-                <pubDate>Tue, 10 Dec 2013 19:20:00 +0100</pubDate>
-               <description>&lt;p&gt;Helga 18. og 19. januar 2014 arrangeres
-&lt;a href=&quot;http://makerfaireoslo.no/no/program/dugnadsnett&quot;&gt;Oslo Maker
-Faire&lt;/a&gt;, og &lt;a href=&quot;http://www.dugnadsnett.no/&quot;&gt;Dugnadsnett for
-alle&lt;/a&gt; har fått plass!  Planen er å ha et bord med en plakat der vi
-forteller om hva Dugnadsnett for alle er for noe, og et lite verksted
-der vi hjelper folk som er interessert i å få opp sin egen mesh-node.
-Jeg gleder meg til å se hvordan prosjektet blir mottatt der.&lt;/p&gt;
-
-&lt;p&gt;Målet med dugnadsnett for alle i Oslo er å få på plass et datanett
-for kommunikasjon ved hjelp av radio-repeaterstasjoner (kalt
-mesh-noder) som gjør at en kan direkte kommunisere med slekt, venner
-og bekjente i Oslo via andre som deltar i dugnadsnettet, samt gjøre
-det mulig komme ut på internett via dugnadsnettet.  Første delmål er å
-kunne sende SMS-meldinger vha. IP-telefoni løsningen
-&lt;a href=&quot;http://www.servalproject.org/&quot;&gt;Serval project&lt;/a&gt; mellom
-deltagerne i Dugnadsnett for alle i Oslo.  Formålet er å ta tilbake
-kontrollen over egen nett-infrastruktur og gjøre det dyrere å bedrive
-massiv innsamling av informasjon om borgernes bruk av datanett.&lt;/p&gt;
-
-&lt;p&gt;Høres dette interessant ut?  Bli med på prosjektet, fortell oss
-hvor du kunne tenke deg å sette opp en radio-repeater (slik at folk i
-nærheten kan finne hverandre ved hjelp av
-&lt;a href=&quot;http://flynor.net/mesh/mesh.php&quot;&gt;kartet over planlagte og
-eksisterende radio-repeatere&lt;/A&gt;), bli med på epostlisten
-&lt;a href=&quot;http://lists.nuug.no/mailman/listinfo/dugnadsnett&quot;&gt;dugnadsnett
-(at) nuug.no&lt;/a&gt; og stikk innom
-&lt;a href=&quot;irc://irc.freenode.net/#dugnadsnett.no&quot;&gt;IRC-kanalen
-#dugnadsnett.no&lt;/a&gt;.  Så langt er det planlagt over 40
-radio-repeatere, med VPN-forbindelser via Internet for å la de delene
-av nettet som ikke når hverandre via radio kunne snakke med hverandre
-likevel.&lt;/p&gt;

+               <description>&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;&lt;a href=&quot;http://www.reactos.org/&quot;&gt;ReactOS&lt;/a&gt; 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 &lt;a href=&quot;http://www.winehq.org/&quot;&gt;the Wine
+project&lt;/a&gt;, which make it possible to run Windows binaries on
+Linux.&lt;/p&gt;
+
+&lt;p&gt;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
+&lt;a href=&quot;http://www.reactos.org/screenshots&quot;&gt;screen shots on the
+project web site&lt;/a&gt; for an idea what it look like (it looks just like
+Windows before metro).&lt;/p&gt;
+
+&lt;p&gt;I do not use ReactOS myself, preferring Linux and Unix like
+operating systems.  I&#39;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&#39;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
+&lt;a href=&quot;http://www.reactos.org/download&quot;&gt;downloading&lt;/a&gt; the
+installation CD, the live CD or the preinstalled virtual machine
+image.&lt;/p&gt;

-               <description>&lt;p&gt;It has been a while since I managed to publish the last interview,
-but the &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu /
-Skolelinux&lt;/a&gt; community is still going strong, and yesterday we even
-had a new school administrator show up on
-&lt;a href=&quot;irc://irc.debian.org/#debian-edu&quot;&gt;#debian-edu&lt;/a&gt; to share
-his success story with installing Debian Edu at their school.  This
-time I have been able to get some helpful comments from the creator of
-Knoppix, Klaus Knopper, who was involved in a Skolelinux project in
-Germany a few years ago.&lt;/p&gt;

+               <description>&lt;p&gt;&lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux&lt;/a&gt;
+keep gaining new users.  Some weeks ago, a person showed up on IRC,
+&lt;a href=&quot;irc://irc.debian.org/#debian-edu&quot;&gt;#debian-edu&lt;/a&gt;, with a
+wish to contribute, and I managed to get a interview with this great
+contributor Roger Marsal to learn more about his background.&lt;/p&gt;

 
 &lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;
 
 
 &lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;
 

-&lt;p&gt;I am Klaus Knopper.  I have a master degree in electrical
-engineering, and is currently professor in information management at
-the university of applied sciences Kaiserslautern / Germany and
-freelance Open Source software developer and consultant.&lt;/p&gt;
-
-&lt;p&gt;All of this is pretty much of the work I spend my days with. Apart
-from teaching, I&#39;m also conducting some more or less experimental
-projects like the &lt;a href=&quot;http://www.knoppix.org&quot;&gt;Knoppix GNU/Linux live
-system&lt;/a&gt; (Debian-based like Skolelinux),
-&lt;a href=&quot;http://www.knopper.net/knoppix-adriane/index-en.html&quot;&gt;ADRIANE&lt;/a&gt;
-(a blind-friendly talking desktop system) and
-&lt;a href=&quot;http://www.knopper.net/linbo/index-en.html&quot;&gt;LINBO&lt;/a&gt;
-(Linux-based network boot console, a fast remote install and repair
-system supporting various operating systems).&lt;/p&gt;
+&lt;p&gt;My name is Roger Marsal, I&#39;m 27 years old (1986 generation) and I
+live in Barcelona, Spain. I&#39;ve got a strong business background and I
+work as a patrimony manager and as a real estate agent.  Additionally,
+I&#39;ve co-founded a British based tech company that is nowadays on the
+last development phase of a new social networking concept.&lt;/p&gt;
+
+&lt;p&gt;I&#39;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.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;

 
 &lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux / Debian Edu
 project?&lt;/strong&gt;&lt;/p&gt;
 
 
 &lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux / Debian Edu
 project?&lt;/strong&gt;&lt;/p&gt;
 

-&lt;p&gt;The credit for this have to go to Kurt Gramlich, who is the German
-coordinator for Skolelinux.  We were looking for an all-in-one open
-source community-supported distribution for schools, and Kurt
-introduced us to Skolelinux for this purpose.&lt;/p&gt;
+&lt;p&gt;I discovered the &lt;a href=&quot;http://www.ltsp.org/&quot;&gt;LTSP&lt;/a&gt; advantages
+with &quot;Ubuntu 12.04 alternate install&quot; 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.&lt;/p&gt;

 
 &lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux / Debian
 Edu?&lt;/strong&gt;&lt;/p&gt;
 
 
 &lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux / Debian
 Edu?&lt;/strong&gt;&lt;/p&gt;
 

-&lt;ul&gt;
-  &lt;li&gt;Quick installation,&lt;/li&gt;
-  &lt;li&gt;works (almost) out of the box,&lt;/li&gt;
-  &lt;li&gt;contains many useful software packages for teaching and learning,&lt;/li&gt;
-  &lt;li&gt;is a purely community-based distro and not controlled by a
-    single company,&lt;/li&gt;
-  &lt;li&gt;has a large number of supporters and teachers who share their
-    experience and problem solutions.&lt;/li&gt;
-&lt;/ul&gt;
+&lt;p&gt;I found a main advantage in that, once you know &quot;the tips and
+tricks&quot;, a new installation just works out of the box. It&#39;s the most
+complete alternative I&#39;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.&lt;/p&gt;

 
 &lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux / Debian
 Edu?&lt;/strong&gt;&lt;/p&gt;
 
 
 &lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux / Debian
 Edu?&lt;/strong&gt;&lt;/p&gt;
 

-&lt;ul&gt;
-  &lt;li&gt;Skolelinux is - as we had to learn - not easily upgradable to
-  the next version.  Opposed to its genuine Debian base, upgrading to
-  a new version means a full new installation from scratch to get it
-  working again reliably.
-
-  &lt;li&gt;Skolelinux is based on Debian/stable, and therefore always a
-  little outdated in terms of program versions compared to Edubuntu or
-  similar educational Linux distros, which rather use Debian/testing
-  as their base.
-
-  &lt;li&gt;Skolelinux has some very self-opinionated and stubborn default
-  configuration which in my opinion adds unnecessary complexity and is
-  not always suitable for a schools needs, the preset network
-  configuration is actually a core definition feature of Skolelinux
-  and not easy to change, so schools sometimes have to change their
-  network configuration to make it &quot;Skolelinux-compatible&quot;.
-
-  &lt;li&gt;Some proposed extensions, which were made available as
-  contribution, like secure examination mode and lecture material
-  distribution and collection, were not accepted into the mainline
-  Skolelinux development and are now not easy to maintain in the
-  future because of Skolelinux somewhat undeterministic update
-  schemes.&lt;/li&gt;
-
-  &lt;li&gt;Skolelinux has only a very tiny number of base developers
-  compared to Debian.&lt;/li&gt;
+&lt;p&gt;I found two main disadvantages.&lt;/p&gt;

 
 

-&lt;/ul&gt;
+&lt;p&gt;I&#39;m not an expert but I&#39;ve got notions and I had to spent a considerable
+amount of time trying to bring up a standard network topology. I&#39;m quite
+stubborn and I just worked until I did but I&#39;m sure many people with few
+resources (not big schools, but academies for example) would have switched
+or dropped.&lt;/p&gt;

 
 

-&lt;p&gt;For these reasons and experience from our project, I would now
-rather consider using plain Debian for schools next time, until
-Skolelinux is more closely integrated into Debian and becomes
-upgradeable without reinstallation.&lt;/p&gt;
+&lt;p&gt;It&#39;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.&lt;/p&gt;

 
 &lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;
 
 
 &lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;
 

-&lt;p&gt;GNU/Linux with LXDE desktop, bash for interactive dialog and
-programming, texlive for documentation and correspondence,
-occasionally LibreOffice for document format conversion. Various
-programming languages for teaching.&lt;/p&gt;
+&lt;p&gt;I use Debian, Firefox, Okular, Inkscape, LibreOffice and
+Virtualbox.&lt;/p&gt;
+

 
 &lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
 get schools to use free software?&lt;/strong&gt;&lt;/p&gt;
 
 
 &lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
 get schools to use free software?&lt;/strong&gt;&lt;/p&gt;
 

-&lt;p&gt;Strong arguments are&lt;/p&gt;
-
-&lt;ul&gt;
-
-  &lt;li&gt;Knowledge is free, and so should be methods and tools for
-    teaching and learning.&lt;/li&gt;
-
-  &lt;li&gt;Students can learn with and use the same software at school, at
-    home, and at their working place without running into license or
-    conversion problems.&lt;/li&gt;
-
-  &lt;li&gt;Closed source or proprietary software hides knowledge rather
-    than exposing it, and proprietary software vendors try to bind
-    customers to certain products.  But teachers need to teach
-    science, not products.&lt;/li&gt;
+&lt;p&gt;I don&#39;t think there is a need for a particular strategy. The free
+attribute in both &quot;freedom&quot; and &quot;no price&quot; meanings is what will
+really bring free software to schools. In my experience I can think of
+the &lt;a href=&quot;http://www.r-project.org/&quot;&gt;&quot;R&quot; statistical language&lt;/a&gt;; a
+few years a ago was an extremely nerd tool for university people.
+Today it&#39;s being increasingly used to teach statistics at many
+different level of studies.  I believe free and open software will
+increasingly gain popularity, but I&#39;m sure schools will be one of the
+first scenarios where this will happen.&lt;/p&gt;

+NRK nå har bestemt seg for
+&lt;a href=&quot;http://www.nuug.no/news/NRK_viser_filmen_om_Datalagringsdirektivet_f_rste_gang_2014_03_31.shtml&quot;&gt;når
+den norske dokumentarfilmen om datalagringsdirektivet skal
+sendes&lt;/a&gt; (se &lt;a href=&quot;http://www.imdb.com/title/tt2832844/&quot;&gt;IMDB&lt;/a&gt;
+for detaljer om filmen) . Første visning blir på NRK2 mandag

+Jeg har sett dokumentaren, og jeg anbefaler enhver å se den selv.  Som
+oppvarming mens vi venter anbefaler jeg Bjørn Stærks kronikk i
+Aftenposten fra i går,
+&lt;a href=&quot;http://www.aftenposten.no/meninger/kronikker/Autoritar-gjokunge-7514915.html&quot;&gt;Autoritær
+gjøkunge&lt;/a&gt;, der han gir en grei skisse av hvor ille det står til med
+retten til privatliv og beskyttelsen av demokrati i Norge og resten
+verden, og helt riktig slår fast at det er vi i databransjen som
+sitter med nøkkelen til å gjøre noe med dette.  Jeg har involvert meg
+i prosjektene &lt;a href=&quot;http://www.dugnadsnett.no/&quot;&gt;dugnadsnett.no&lt;/a&gt;
+og &lt;a href=&quot;https://wiki.debian.org/FreedomBox&quot;&gt;FreedomBox&lt;/a&gt; for å
+forsøke å gjøre litt selv for å bedre situasjonen, men det er mye
+hardt arbeid fra mange flere enn meg som gjenstår før vi kan sies å ha
+gjenopprettet balansen.&lt;/p&gt;
+
+&lt;p&gt;Jeg regner med at nettutgaven dukker opp på
+&lt;a href=&quot;http://tv.nrk.no/program/koid75005313/tema-dine-digitale-spor-datalagringsdirektivet&quot;&gt;NRKs
+side om filmen om datalagringsdirektivet&lt;/a&gt; om fem dager.  Hold et
+øye med siden, og tips venner og slekt om at de også bør se den.&lt;/p&gt;

+               <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Public_Trusted_Timestamping_services_for_everyone.html</guid>
+                <pubDate>Tue, 25 Mar 2014 12:50:00 +0100</pubDate>
+               <description>&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;A solution to these problems is to have a trusted third party
+&quot;stamp&quot; the document and verify that at some given time the document
+looked a given way.  Such
+&lt;a href=&quot;https://en.wikipedia.org/wiki/Notarius&quot;&gt;notarius&lt;/a&gt; service
+have been around for thousands of years, and its digital equivalent is
+called a
+&lt;a href=&quot;http://en.wikipedia.org/wiki/Trusted_timestamping&quot;&gt;trusted
+timestamping service&lt;/a&gt;.  &lt;a href=&quot;http://www.ietf.org/&quot;&gt;The Internet
+Engineering Task Force&lt;/a&gt; standardised how such service could work a
+few years ago as &lt;a href=&quot;http://tools.ietf.org/html/rfc3161&quot;&gt;RFC
+3161&lt;/a&gt;.  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
+&quot;&lt;a href=&quot;https://duckduckgo.com/?q=rfc+3161+service&quot;&gt;rfc 3161
+service&lt;/a&gt;&quot; pointed me to at least
+&lt;a href=&quot;https://www.digistamp.com/technical/how-a-digital-time-stamp-works/&quot;&gt;DigiStamp&lt;/a&gt;,
+&lt;a href=&quot;http://www.quovadisglobal.co.uk/CertificateServices/SigningServices/TimeStamp.aspx&quot;&gt;Quo
+Vadis&lt;/a&gt;,
+&lt;a href=&quot;https://www.globalsign.com/timestamp-service/&quot;&gt;Global Sign&lt;/a&gt;
+and &lt;a href=&quot;http://www.globaltrustfinder.com/TSADefault.aspx&quot;&gt;Global
+Trust Finder&lt;/a&gt;.  The system work as long as the private key of the
+trusted third party is not compromised.&lt;/p&gt;
+
+&lt;p&gt;But as far as I can tell, there are very few public trusted
+timestamp services available for everyone.  I&#39;ve been looking for one
+for a while now. But yesterday I found one over at
+&lt;a href=&quot;https://www.pki.dfn.de/zeitstempeldienst/&quot;&gt;Deutches
+Forschungsnetz&lt;/a&gt; mentioned in
+&lt;a href=&quot;http://www.d-mueller.de/blog/dealing-with-trusted-timestamps-in-php-rfc-3161/&quot;&gt;a
+blog by David Müller&lt;/a&gt;.  I then found
+&lt;a href=&quot;http://www.rz.uni-greifswald.de/support/dfn-pki-zertifikate/zeitstempeldienst.html&quot;&gt;a
+good recipe on how to use the service&lt;/a&gt; over at the University of
+Greifswald.&lt;/p&gt;
+
+&lt;p&gt;&lt;a href=&quot;http://www.openssl.org/&quot;&gt;The OpenSSL library&lt;/a&gt; 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:&lt;/p&gt;

 
 

-  &lt;li&gt;If you have everything you for daily work as open source, what
-    would you need proprietary software for?&lt;/li&gt;
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+#!/bin/sh
+set -e
+url=&quot;http://zeitstempel.dfn.de&quot;
+caurl=&quot;https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt&quot;
+reqfile=$(mktemp -t tmp.XXXXXXXXXX.tsq)
+resfile=$(mktemp -t tmp.XXXXXXXXXX.tsr)
+cafile=chain.txt
+if [ ! -f $cafile ] ; then
+    wget -O $cafile &quot;$caurl&quot;
+fi
+openssl ts -query -data &quot;$1&quot; -cert | tee &quot;$reqfile&quot; \
+    | /usr/lib/ssl/misc/tsget -h &quot;$url&quot; -o &quot;$resfile&quot;
+openssl ts -reply -in &quot;$resfile&quot; -text 1&gt;&amp;2
+openssl ts -verify -data &quot;$1&quot; -in &quot;$resfile&quot; -CAfile &quot;$cafile&quot; 1&gt;&amp;2
+base64 &lt; &quot;$resfile&quot;
+rm &quot;$reqfile&quot; &quot;$resfile&quot;
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;

 
 

-&lt;/ul&gt;
+&lt;p&gt;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
+&lt;a href=&quot;http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=742553&quot;&gt;a bug
+in the tsget script&lt;/a&gt;, 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.&lt;/p&gt;
+
+&lt;p&gt;But the Internet need more public trusted timestamp services.
+Perhaps something for &lt;a href=&quot;http://www.uninett.no/&quot;&gt;Uninett&lt;/a&gt; or
+my work place the &lt;a href=&quot;http://www.uio.no/&quot;&gt;University of Oslo&lt;/a&gt;
+to set up?&lt;/p&gt;

+               <description>&lt;p&gt;Keeping your DVD collection safe from scratches and curious
+children fingers while still having it available when you want to see a
+movie is not straight forward.  My preferred method at the moment is
+to store a full copy of the ISO on a hard drive, and use VLC, Popcorn
+Hour or other useful players to view the resulting file.  This way the
+subtitles and bonus material are still available and using the ISO is
+just like inserting the original DVD record in the DVD player.&lt;/p&gt;
+
+&lt;p&gt;Earlier I used dd for taking security copies, but it do not handle
+DVDs giving read errors (which are quite a few of them).  I&#39;ve also
+tried using
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Ripping_problematic_DVDs_using_dvdbackup_and_genisoimage.html&quot;&gt;dvdbackup
+and genisoimage&lt;/a&gt;, but these days I use the marvellous python library
+and program
+&lt;a href=&quot;http://bblank.thinkmo.de/blog/new-software-python-dvdvideo&quot;&gt;python-dvdvideo&lt;/a&gt;
+written by Bastian Blank.  It is
+&lt;a href=&quot;http://packages.qa.debian.org/p/python-dvdvideo.html&quot;&gt;in Debian
+already&lt;/a&gt; and the binary package name is python3-dvdvideo. Instead
+of trying to read every block from the DVD, it parses the file
+structure and figure out which block on the DVD is actually in used,
+and only read those blocks from the DVD.  This work surprisingly well,
+and I have been able to almost backup my entire DVD collection using
+this method.&lt;/p&gt;
+
+&lt;p&gt;So far, python-dvdvideo have failed on between 10 and
+20 DVDs, which is a small fraction of my collection.  The most common
+problem is
+&lt;a href=&quot;https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=720831&quot;&gt;DVDs
+using UTF-16 instead of UTF-8 characters&lt;/a&gt;, which according to
+Bastian is against the DVD specification (and seem to cause some
+players to fail too).  A rarer problem is what seem to be inconsistent
+DVD structures, as the python library
+&lt;a href=&quot;https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=723079&quot;&gt;claim
+there is a overlap between objects&lt;/a&gt;.  An equally rare problem claim
+&lt;a href=&quot;https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=741878&quot;&gt;some
+value is out of range&lt;/a&gt;.  No idea what is going on there.  I wish I
+knew enough about the DVD format to fix these, to ensure my movie
+collection will stay with me in the future.&lt;/p&gt;
+
+&lt;p&gt;So, if you need to keep your DVDs safe, back them up using
+python-dvdvideo. :)&lt;/p&gt;

+               <description>&lt;p&gt;Det offentlige Norge har mye kunnskap og informasjon.  Men hvordan
+kan en få tilgang til den på en enkel måte?  Takket være et lite
+knippe lover og tilhørende forskrifter, blant annet
+&lt;a href=&quot;http://lovdata.no/dokument/NL/lov/2006-05-19-16&quot;&gt;offentlighetsloven&lt;/a&gt;,
+&lt;a href=&quot;http://lovdata.no/dokument/NL/lov/2003-05-09-31&quot;&gt;miljøinformasjonsloven&lt;/a&gt;
+og
+&lt;a href=&quot;http://lovdata.no/dokument/NL/lov/1967-02-10/&quot;&gt;forvaltningsloven&lt;/a&gt;
+har en rett til å spørre det offentlige og få svar.  Men det finnes
+intet offentlig arkiv over hva andre har spurt om, og dermed risikerer en
+å måtte forstyrre myndighetene gang på gang for å få tak i samme
+informasjonen på nytt.  &lt;a href=&quot;http://www.mysociety.org/&quot;&gt;Britiske
+mySociety&lt;/a&gt; har laget tjenesten
+&lt;a href=&quot;http://www.whatdotheyknow.com/&quot;&gt;WhatDoTheyKnow&lt;/a&gt; som gjør
+noe med dette.  I Storbritannia blir WhatdoTheyKnow brukt i
+&lt;a href=&quot;http://www.mysociety.org/2011/07/01/whatdotheyknows-share-of-central-government-foi-requests-q2-2011/&quot;&gt;ca
+15% av alle innsynsforespørsler mot sentraladministrasjonen&lt;/a&gt;.
+Prosjektet heter &lt;a href=&quot;http://www.alaveteli.org/&quot;&gt;Alaveteli&lt;/A&gt;, og
+er takk i bruk en rekke steder etter at løsningen ble generalisert og
+gjort mulig å oversette.  Den hjelper borgerne med å be om innsyn,
+rådgir ved purringer og klager og lar alle se hvilke henvendelser som
+er sendt til det offentlige og hvilke svar som er kommet inn, i et
+søkpart arkiv.  Her i Norge holder vi i foreningen NUUG på å få opp en
+norsk utgave av Alaveteli, og her trenger vi din hjelp med
+oversettelsen.&lt;/p&gt;
+
+&lt;p&gt;Så langt er 76 % av Alaveteli oversatt til norsk bokmål, men vi
+skulle gjerne vært oppe i 100 % før lansering.  Oversettelsen gjøres
+på &lt;a href=&quot;https://www.transifex.com/projects/p/alaveteli/&quot;&gt;Transifex,
+der enhver som registrerer seg&lt;/a&gt; og ber om tilgang til
+bokmålsoversettelsen får bidra.  Vi har satt opp en test av tjenesten
+(som ikke sender epost til det offentlige, kun til oss som holder på å
+sette opp tjenesten) på maskinen
+&lt;a href=&quot;http://alaveteli-dev.nuug.no/&quot;&gt;alaveteli-dev.nuug.no&lt;/a&gt;, der
+en kan se hvordan de oversatte meldingen blir seende ut på nettsiden.
+Når tjenesten lanseres vil den hete
+&lt;a href=&quot;https://www.mimesbrønn.no/&quot;&gt;Mimes brønn&lt;/a&gt;, etter
+visdomskilden som Odin måtte gi øyet sitt for å få drikke i.  Den
+nettsiden er er ennå ikke klar til bruk.&lt;/p&gt;
+
+&lt;p&gt;Hvis noen vil oversette til nynorsk også, så skal vi finne ut
+hvordan vi lager en flerspråklig tjeneste.  Men i første omgang er
+fokus på bokmålsoversettelsen, der vi selv har nok peiling til å ha
+fått oversatt 76%, men trenger hjelp for å komme helt i mål. :)&lt;/p&gt;

+               <description>&lt;p&gt;The &lt;a href=&quot;https://wiki.debian.org/FreedomBox&quot;&gt;Freedombox
+project&lt;/a&gt; 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).&lt;/p&gt;
+
+&lt;p&gt;And what day could be better than the Pi day to announce that the
+new version will provide &quot;hard drive&quot; / 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
+&lt;a href=&quot;http://packages.qa.debian.org/vmdebootstrap&quot;&gt;vmdebootstrap&lt;/a&gt;
+with a user with sudo access to become root:
+
+&lt;pre&gt;
+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
+&lt;/pre&gt;
+
+&lt;p&gt;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 &lt;a
+href=&quot;https://bugs.debian.org/741407&quot;&gt;a race condition in
+vmdebootstrap&lt;/a&gt;, the build might fail without the patch to the
+kpartx call.&lt;/p&gt;
+
+&lt;p&gt;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:&lt;/p&gt;
+
+&lt;pre&gt;
+url=&lt;a href=&quot;http://www.reinholdtsen.name/freedombox/preseed-jessie.dat&quot;&gt;http://www.reinholdtsen.name/freedombox/preseed-jessie.dat&lt;/a&gt;
+&lt;/pre&gt;
+
+&lt;p&gt;But note that due to &lt;a href=&quot;https://bugs.debian.org/740673&quot;&gt;a
+recently introduced bug in apt in Jessie&lt;/a&gt;, the installer will
+currently hang while setting up APT sources.  Killing the
+&#39;&lt;tt&gt;apt-cdrom ident&lt;/tt&gt;&#39; 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.&lt;/p&gt;
+
+&lt;p&gt;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
+&lt;a href=&quot;irc://irc.debian.org:6667/%23freedombox&quot;&gt;IRC (#freedombox on
+irc.debian.org)&lt;/a&gt; and
+&lt;a href=&quot;http://lists.alioth.debian.org/mailman/listinfo/freedombox-discuss&quot;&gt;the
+mailing list&lt;/a&gt; if you want to help make this vision come true.&lt;/p&gt;

+               <description>&lt;p&gt;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 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux&lt;/a&gt;, 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
+&lt;a href=&quot;http://www.slxdrift.no/&quot;&gt;Skolelinux Drift AS&lt;/a&gt;, where I am
+on the board of directors, asked about how to do this.  The steps to
+get this working are the following:&lt;/p&gt;

 
 

-&lt;/ul&gt;
+&lt;p&gt;&lt;ol&gt;
+
+&lt;li&gt;Add new storage server in DNS.  I use nas-server.intern as the
+example host here.&lt;/li&gt;
+
+&lt;li&gt;Add automoun LDAP information about this server in LDAP, to allow
+all clients to automatically mount it on reqeust.&lt;/li&gt;
+
+&lt;li&gt;Add the relevant entries in tjener.intern:/etc/fstab, because
+tjener.intern do not use automount to avoid mounting loops.&lt;/li&gt;
+
+&lt;/ol&gt;&lt;/p&gt;
+
+&lt;p&gt;DNS entries are added in GOsa², and not described here.  Follow the
+&lt;a href=&quot;https://wiki.debian.org/DebianEdu/Documentation/Wheezy/GettingStarted&quot;&gt;instructions
+in the manual&lt;/a&gt; (Machine Management with GOsa² in section Getting
+started).&lt;/p&gt;
+
+&lt;p&gt;Ensure that the NFS export points on the server are exported to the
+relevant subnets or machines:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+root@tjener:~# showmount -e nas-server
+Export list for nas-server:
+/storage         10.0.0.0/8
+root@tjener:~#
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+ldapvi --ldap-conf -ZD &#39;(cn=admin)&#39; -b ou=automount,dc=skole,dc=skolelinux,dc=no
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;When the editor show up, add the following LDAP objects at the
+bottom of the document.  The &quot;/&amp;&quot; 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.&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+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:/&amp;
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;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 &quot;mount -a&quot; to mount them.&lt;/p&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;
-
-&lt;p&gt;&lt;a href=&quot;http://dinis.linguateca.pt/Diana/ImotMSUiO.html&quot;&gt;Underskriftslista
-for oss som er mot endringen&lt;/a&gt;, som omtales i artiklene, er fortsatt
-åpen for de som vil signere på oppropet.  Akkurat nå er det 298
-personer som har signert.&lt;/p&gt;
+&lt;p&gt;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.&lt;/p&gt;
