- <div class="date">25th March 2014</div>
- <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>

-both server and tools to use and set up your own signing service. See

- <div class="body"><p>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.</p>
-
-<p>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've also
-tried using
-<a href="http://people.skolelinux.org/pere/blog/Ripping_problematic_DVDs_using_dvdbackup_and_genisoimage.html">dvdbackup
-and genisoimage</a>, but these days I use the marvellous python library
-and program
-<a href="http://bblank.thinkmo.de/blog/new-software-python-dvdvideo">python-dvdvideo</a>
-written by Bastian Blank. It is
-<a href="http://packages.qa.debian.org/p/python-dvdvideo.html">in Debian
-already</a> 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.</p>
-
-<p>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
-<a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=720831">DVDs
-using UTF-16 instead of UTF-8 characters</a>, 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
-<a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=723079">claim
-there is a overlap between objects</a>. An equally rare problem claim
-<a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=741878">some
-value is out of range</a>. 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.</p>
-
-<p>So, if you need to keep your DVDs safe, back them up using
-python-dvdvideo. :)</p>

+plugin. Gnash implement support for the AVM1 format (and not the
+newer AVM2 format - see
+<a href="http://lightspark.github.io/">Lightspark</a> for that one),
+allowing several flash based sites to work. Thanks to the friendly
+developers at Youtube, it also work with Youtube videos, because the

+support, but it has not happened yet. If you install both Lightspark
+and Gnash, Lightspark will invoke Gnash if it find a AVM1 flash file,
+so you can get both handled as free software. Unfortunately,
+Lightspark so far only implement a small subset of AVM2, and many

+
+<p>A few months ago, I started looking at
+<a href="http://scan.coverity.com/">Coverity</a>, the static source
+checker used to find heaps and heaps of bugs in free software (thanks
+to the donation of a scanning service to free software projects by the
+company developing this non-free code checker), and Gnash was one of
+the projects I decided to check out. Coverity is able to find lock
+errors, memory errors, dead code and more. A few days ago they even
+extended it to also be able to find the heartbleed bug in OpenSSL.
+There are heaps of checks being done on the instrumented code, and the
+amount of bogus warnings is quite low compared to the other static
+code checkers I have tested over the years.</p>
+
+<p>Since a few weeks ago, I've been working with the other Gnash
+developers squashing bugs discovered by Coverity. I was quite happy
+today when I checked the current status and saw that of the 777 issues
+detected so far, 374 are marked as fixed. This make me confident that
+the next Gnash release will be more stable and more dependable than
+the previous one. Most of the reported issues were and are in the
+test suite, but it also found a few in the rest of the code.</p>

+ <div class="title"><a href="http://people.skolelinux.org/pere/blog/Install_hardware_dependent_packages_using_tasksel__Isenkram_0_7_.html">Install hardware dependent packages using tasksel (Isenkram 0.7)</a></div>
+ <div class="date">23rd April 2014</div>
+ <div class="body"><p>It would be nice if it was easier in Debian to get all the hardware
+related packages relevant for the computer installed automatically.
+So I implemented one, using
+<a href="http://packages.qa.debian.org/isenkram">my Isenkram
+package</a>. To use it, install the tasksel and isenkram packages and
+run tasksel as user root. You should be presented with a new option,
+"Hardware specific packages (autodetected by isenkram)". When you
+select it, tasksel will install the packages isenkram claim is fit for
+the current hardware, hot pluggable or not.<p>
+
+<p>The implementation is in two files, one is the tasksel menu entry
+description, and the other is the script used to extract the list of
+packages to install. The first part is in
+<tt>/usr/share/tasksel/descs/isenkram.desc</tt> and look like
+this:</p>
+
+<p><blockquote><pre>
+Task: isenkram
+Section: hardware
+Description: Hardware specific packages (autodetected by isenkram)
+ Based on the detected hardware various hardware specific packages are
+ proposed.
+Test-new-install: mark show
+Relevance: 8
+Packages: for-current-hardware
+</pre></blockquote></p>
+
+<p>The second part is in
+<tt>/usr/lib/tasksel/packages/for-current-hardware</tt> and look like
+this:</p>
+
+<p><blockquote><pre>
+#!/bin/sh
+#
+(
+ isenkram-lookup
+ isenkram-autoinstall-firmware -l
+) | sort -u
+</pre></blockquote></p>
+
+<p>All in all, a very short and simple implementation making it
+trivial to install the hardware dependent package we all may want to
+have installed on our machines. I've not been able to find a way to
+get tasksel to tell you exactly which packages it plan to install
+before doing the installation. So if you are curious or careful,
+check the output from the isenkram-* command line tools first.</p>
+
+<p>The information about which packages are handling which hardware is
+fetched either from the isenkram package itself in
+/usr/share/isenkram/, from git.debian.org or from the APT package
+database (using the Modaliases header). The APT package database
+parsing have caused a nasty resource leak in the isenkram daemon (bugs
+<a href="http://bugs.debian.org/719837">#719837</a> and
+<a href="http://bugs.debian.org/730704">#730704</a>). The cause is in
+the python-apt code (bug
+<a href="http://bugs.debian.org/745487">#745487</a>), but using a
+workaround I was able to get rid of the file descriptor leak and
+reduce the memory leak from ~30 MiB per hardware detection down to
+around 2 MiB per hardware detection. It should make the desktop
+daemon a lot more useful. The fix is in version 0.7 uploaded to
+unstable today.</p>
+
+<p>I believe the current way of mapping hardware to packages in
+Isenkram is is a good draft, but in the future I expect isenkram to
+use the AppStream data source for this. A proposal for getting proper
+AppStream support into Debian is floating around as
+<a href="https://wiki.debian.org/DEP-11">DEP-11</a>, and
+<a href="https://wiki.debian.org/SummerOfCode2014/Projects#SummerOfCode2014.2FProjects.2FAppStreamDEP11Implementation.AppStream.2FDEP-11_for_the_Debian_Archive">GSoC
+project</a> will take place this summer to improve the situation. I
+look forward to seeing the result, and welcome patches for isenkram to
+start using the information when it is ready.</p>
+
+<p>If you want your package to map to some specific hardware, either
+add a "Xb-Modaliases" header to your control file like I did in
+<a href="http://packages.qa.debian.org/pymissile">the pymissile
+package</a> or submit a bug report with the details to the isenkram
+package. See also
+<a href="http://people.skolelinux.org/pere/blog/tags/isenkram/">all my
+blog posts tagged isenkram</a> for details on the notation. I expect
+the information will be migrated to AppStream eventually, but for the
+moment I got no better place to store it.</p>

-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

+project</a> is working on providing the software and hardware to make
+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 is still going strong, and
+today a major mile stone was reached.</p>
+
+<p>Today, the last of the packages currently used by the project to
+created the system images were accepted into Debian Unstable. It was
+the freedombox-setup package, which is used to configure the images
+during build and on the first boot. Now all one need to get going is
+the build code from the freedom-maker git repository and packages from
+Debian. And once the freedombox-setup package enter testing, we can
+build everything directly from Debian. :)</p>
+
+<p>Some key packages used by Freedombox are

+are plans to integrate more packages into the setup. User
+documentation is maintained on the Debian wiki. Please
+<a href="https://wiki.debian.org/FreedomBox/Manual/Jessie">check out
+the manual</a> and help us improve it.</p>
+
+<p>To test for yourself and create boot images with the FreedomBox
+setup, run this on a Debian machine using a user with sudo rights to
+become root:</p>
+
+<p><pre>
sudo apt-get install git vmdebootstrap mercurial python-docutils \

<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

+devices. See the README in the freedom-maker git repo for more
+details on the build. If you do not want all three images, trim the
+make line. Note that the virtualbox-image target is not really
+virtualbox specific. It create a x86 image usable in kvm, qemu,
+vmware and any other x86 virtual machine environment. You might need
+the version of vmdebootstrap in Jessie to get the build working, as it
+include fixes for a race condition with kpartx.</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>
+</pre></p>
+
+<p>I have not tested it myself the last few weeks, so I do not know if
+it still work.</p>
-<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>If you wonder how to help, one task you could look at is using
+systemd as the boot system. It will become the default for Linux in
+Jessie, so we need to make sure it is usable on the Freedombox. I did
+a simple test a few weeks ago, and noticed dnsmasq failed to start
+during boot when using systemd. I suspect there are other problems
+too. :) To detect problems, there is a test suite included, which can
+be run from the plinth web interface.</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

+ <div class="date">11th April 2014</div>
+ <div class="body"><p>For 12 år siden, skrev jeg et lite notat om
+<a href="http://i18n.skolelinux.no/localekoder.txt">bruk av språkkoder
+i Norge</a>. Jeg ble nettopp minnet på dette da jeg fikk spørsmål om
+notatet fortsatt var aktuelt, og tenkte det var greit å repetere hva
+som fortsatt gjelder. Det jeg skrev da er fortsatt like aktuelt.</p>
+
+<p>Når en velger språk i programmer på unix, så velger en blant mange
+språkkoder. For språk i Norge anbefales følgende språkkoder (anbefalt
+locale i parantes):</p>
+
+<p><dl>
+<dt>nb (nb_NO)</dt><dd>Bokmål i Norge</dd>
+<dt>nn (nn_NO)</dt><dd>Nynorsk i Norge</dd>
+<dt>se (se_NO)</dt><dd>Nordsamisk i Norge</dd>
+</dl></p>
+
+<p>Alle programmer som bruker andre koder bør endres.</p>
+
+<p>Språkkoden bør brukes når .po-filer navngis og installeres. Dette
+er ikke det samme som locale-koden. For Norsk Bokmål, så bør filene
+være navngitt nb.po, mens locale (LANG) bør være nb_NO.</p>
+
+<p>Hvis vi ikke får standardisert de kodene i alle programmene med
+norske oversettelser, så er det umulig å gi LANG-variablen ett innhold
+som fungerer for alle programmer.</p>
+
+<p>Språkkodene er de offisielle kodene fra ISO 639, og bruken av dem i
+forbindelse med POSIX localer er standardisert i RFC 3066 og ISO
+15897. Denne anbefalingen er i tråd med de angitte standardene.</p>
+
+<p>Følgende koder er eller har vært i bruk som locale-verdier for
+"norske" språk. Disse bør unngås, og erstattes når de oppdages:</p>
+
+<p><table>
+<tr><td>norwegian</td><td>-> nb_NO</td></tr>
+<tr><td>bokmål </td><td>-> nb_NO</td></tr>
+<tr><td>bokmal </td><td>-> nb_NO</td></tr>
+<tr><td>nynorsk </td><td>-> nn_NO</td></tr>
+<tr><td>no </td><td>-> nb_NO</td></tr>
+<tr><td>no_NO </td><td>-> nb_NO</td></tr>
+<tr><td>no_NY </td><td>-> nn_NO</td></tr>
+<tr><td>sme_NO </td><td>-> se_NO</td></tr>
+</table></p>
+
+<p>Merk at når det gjelder de samiske språkene, at se_NO i praksis
+henviser til nordsamisk i Norge, mens f.eks. smj_NO henviser til
+lulesamisk. Dette notatet er dog ikke ment å gi råd rundt samiske

+ <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>
-root@tjener:~# showmount -e nas-server
-Export list for nas-server:
-/storage 10.0.0.0/8
-root@tjener:~#
+[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>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>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>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>
+# 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:

+..contents..
+..ext_attributes..
+Compressing and uploading metadata...
+Wrote 0.00 MB of compressed metadata.
+# </pre></blockquote></p>
+
+<p>The next step is mounting the file system to make the storage available.
<p><blockquote><pre>
-ldapvi --ldap-conf -ZD '(cn=admin)' -b ou=automount,dc=skole,dc=skolelinux,dc=no
+# mount.s3ql --cachedir /var/lib/s3ql-cache --authfile /root/.s3ql/authinfo2 \
+ --ssl --allow-root s3c://s.greenqloud.com:443/bucket-name /s3ql

+Filesystem Size Used Avail Use% Mounted on
+s3c://s.greenqloud.com:443/bucket-name 1.0T 0 1.0T 0% /s3ql
+#
</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>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>
-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:/&
+# umount.s3ql /s3ql
+#
</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>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>
-<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>

-<a href="http://www.nuug.no/aktiviteter/20140211-noark/">presentert hos
-NUUG</a> (video
-<a href="https://www.youtube.com/watch?v=JCb_dNS3MHQ">på youtube
-foreløbig</a>), og det fikk meg til å titte litt mer på NOARK5,
-standarden for arkivhåndtering i det offentlige Norge. Jeg lurer på
-om denne kjernen kan være nyttig i et par av mine prosjekter, og for ett
-av dem er det mest aktuelt å lagre epost. Jeg klarte ikke finne noen
-anbefaling om hvordan RFC 822-formattert epost (aka Internett-epost)
-burde lagres i NOARK5, selv om jeg vet at noen arkiver tar
-PDF-utskrift av eposten med sitt epostprogram og så arkiverer PDF-en
-(eller enda værre, tar papirutskrift og lagrer bildet av eposten som
-PDF i arkivet).</p>
-
-<p>Det er ikke så mange formater som er akseptert av riksarkivet til
-langtidsoppbevaring av offentlige arkiver, og PDF og XML er de mest
-aktuelle i så måte. Det slo meg at det måtte da finnes en eller annen
-egnet XML-representasjon og at det kanskje var enighet om hvilken som
-burde brukes, så jeg tok mot til meg og spurte
-<a href="http://samdok.com/">SAMDOK</a>, en gruppe tilknyttet
-arkivverket som ser ut til å jobbe med NOARK-samhandling, om de hadde
-noen anbefalinger:
-
-<p><blockquote>
-<p>Hei.</p>
-
-<p>Usikker på om dette er riktig forum å ta opp mitt spørsmål, men jeg
-lurer på om det er definert en anbefaling om hvordan RFC
-822-formatterte epost (aka vanlig Internet-epost) bør lages håndteres
-i NOARK5, slik at en bevarer all informasjon i eposten
-(f.eks. Received-linjer). Finnes det en anbefalt XML-mapping ala den
-som beskrives på
-<URL: <a href="https://www.informit.com/articles/article.aspx?p=32074">https://www.informit.com/articles/article.aspx?p=32074</a> >? Mitt
-mål er at det skal være mulig å lagre eposten i en NOARK5-kjerne og
-kunne få ut en identisk formattert kopi av opprinnelig epost ved
-behov.</p>
-</blockquote></p>
-
-<p>Postmottaker hos SAMDOK mente spørsmålet heller burde stilles
-direkte til riksarkivet, og jeg fikk i dag svar derfra formulert av
-seniorrådgiver Geir Ivar Tungesvik:</p>
-
-<p><blockquote>
-<p>Riksarkivet har ingen anbefalinger når det gjelder konvertering fra
-e-post til XML. Det står arkivskaper fritt å eventuelt definere/bruke
-eget format. Inklusive da - som det spørres om - et format der det er
-mulig å re-etablere e-post format ut fra XML-en. XML (e-post)
-dokumenter må være referert i arkivstrukturen, og det må vedlegges et
-gyldig XML skjema (.xsd) for XML-filene. Arkivskaper står altså fritt
-til å gjøre hva de vil, bare det dokumenteres og det kan dannes et
-utrekk ved avlevering til depot.</p>
-
-<p>De obligatoriske kravene i Noark 5 standarden må altså oppfylles -
-etter dialog med Riksarkivet i forbindelse med godkjenning. For
-offentlige arkiv er det særlig viktig med filene loependeJournal.xml
-og offentligJournal.xml. Private arkiv som vil forholde seg til Noark
-5 standarden er selvsagt frie til å bruke det som er relevant for dem
-av obligatoriske krav.</p>
-</blockquote></p>
-
-<p>Det ser dermed ut for meg som om det er et lite behov for å
-standardisere XML-lagring av RFC-822-formatterte meldinger. Noen som
-vet om god spesifikasjon i så måte? I tillegg til den omtalt over,
-har jeg kommet over flere aktuelle beskrivelser (søk på "rfc 822
-xml", så finner du aktuelle alternativer).</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

+<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
+quite different and you will have to figure out what suits 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>
+
+<p>As usual, if you use Bitcoin and want to show your support of my
+activities, please send Bitcoin donations to my address

+ <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="date"> 3rd February 2014</div>
- <div class="body"><p>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
-<a href="https://teythoon.cryptobitch.de//categories/gsoc.html">great
-Google Summer of Code work</a> 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
-<a href="http://ftp.debian-ports.org/debian-cd/hurd-i386/current/debian-hurd.img.tar.gz">http://ftp.debian-ports.org/debian-cd/hurd-i386/current/debian-hurd.img.tar.gz</a>,
-and started it using virt-manager.</p>
-
-<p>The first think I had to do after logging in (root without any
-password) was to get the network operational. I followed
-<a href="https://www.debian.org/ports/hurd/hurd-install">the
-instructions on the Debian GNU/Hurd ports page</a> and ran these
-commands as root to get the machine to accept a IP address from the
-kvm internal DHCP server:</p>
-
-<p><blockquote><pre>
-settrans -fgap /dev/netdde /hurd/netdde
-kill $(ps -ef|awk '/[p]finet/ { print $2}')
-kill $(ps -ef|awk '/[d]evnode/ { print $2}')
-dhclient /dev/eth0
-</pre></blockquote></p>
-
-<p>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.</p>
-
-<p>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.</p>
-
-<p>Run these commands as root to upgrade and test the new sysvinit
-stuff:</p>
-
-<p><blockquote><pre>
-cat > /etc/apt/sources.list.d/experimental.list <<EOF
-deb http://http.debian.net/debian/ experimental main
-EOF

-<p>To reboot after switching boot system, you have to use
-<tt>reboot-hurd</tt> instead of just <tt>reboot</tt>, as there is not
-yet a sysvinit process able to receive the signals from the normal
-'reboot' 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.
-
-<p>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:</p>
-
-<p><blockquote><pre>
-cat > /etc/apt/sources.list.d/hurd-ci.list <<EOF
-deb http://darnassus.sceen.net/~teythoon/hurd-ci/ sid main
-EOF
-</pre></blockquote></p>
-
-<p>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 "unofficial" packages installed:</p>
-
-<p><blockquote><pre>
-# aptitude search '?narrow(?version(CURRENT),?origin(Debian Ports))'
-i emacs - GNU Emacs editor (metapackage)

+ <div class="date">30th March 2014</div>
+ <div class="body"><p><a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>
+keep gaining new users. Some weeks ago, a person showed up on IRC,
+<a href="irc://irc.debian.org/#debian-edu">#debian-edu</a>, with a
+wish to contribute, and I managed to get a interview with this great
+contributor Roger Marsal to learn more about his background.</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><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><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><strong>What do you see as the disadvantages of Skolelinux / Debian
+Edu?</strong></p>
+
+<p>I found two main disadvantages.</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>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>Which free software do you use daily?</strong></p>
+
+<p>I use Debian, Firefox, Okular, Inkscape, LibreOffice and
+Virtualbox.</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
+attribute in both "freedom" and "no price" meanings is what will
+really bring free software to schools. In my experience I can think of
+the <a href="http://www.r-project.org/">"R" statistical language</a>; a
+few years a ago was an extremely nerd tool for university people.
+Today it'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'm sure schools will be one of the
+first scenarios where this will happen.</p>

+ <div class="date">26th March 2014</div>
+ <div class="body"><p><a href="http://www.nuug.no/">Foreningen NUUG</a> melder i natt at
+NRK nå har bestemt seg for
+<a href="http://www.nuug.no/news/NRK_viser_filmen_om_Datalagringsdirektivet_f_rste_gang_2014_03_31.shtml">når
+den norske dokumentarfilmen om datalagringsdirektivet skal
+sendes</a> (se <a href="http://www.imdb.com/title/tt2832844/">IMDB</a>
+for detaljer om filmen) . Første visning blir på NRK2 mandag
+2014-03-31 kl. 19:50, og deretter visninger onsdag 2014-04-02
+kl. 12:30, fredag 2014-04-04 kl. 19:40 og søndag 2014-04-06 kl. 15:10.
+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,
+<a href="http://www.aftenposten.no/meninger/kronikker/Autoritar-gjokunge-7514915.html">Autoritær
+gjøkunge</a>, 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 <a href="http://www.dugnadsnett.no/">dugnadsnett.no</a>
+og <a href="https://wiki.debian.org/FreedomBox">FreedomBox</a> 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.</p>
-<p>All in all, testing hurd has been an interesting experience. :)
-X.org did not work out of the box and I never took the time to follow
-the porters instructions to fix it. This time I was interested in the
-command line stuff.<p>
+<p>Jeg regner med at nettutgaven dukker opp på
+<a href="http://tv.nrk.no/program/koid75005313/tema-dine-digitale-spor-datalagringsdirektivet">NRKs
+side om filmen om datalagringsdirektivet</a> om fem dager. Hold et
+øye med siden, og tips venner og slekt om at de også bør se den.</p>
