- <description><p>I spent last weekend at <a href="http://www.makercon.no/">Makercon
-Nordic</a>, a great conference and workshop for makers in Norway and
-the surrounding countries. I had volunteered on behalf of the
-Norwegian Unix Users Group (NUUG) to video record the talks, and we
-had a great and exhausting time recording the entire day, two days in
-a row. There were only two of us, Hans-Petter and me, and we used the
-regular video equipment for NUUG, with a
-<a href="http://dvswitch.alioth.debian.org/wiki/">dvswitch</a>, a
-camera and a VGA to DV convert box, and mixed video and slides
-live.</p>
-
-<p>Hans-Petter did the post-processing, consisting of uploading the
-around 180 GiB of raw video to Youtube, and the result is
-<a href="https://www.youtube.com/user/MakerConNordic/">now becoming
-public</a> on the MakerConNordic account. The videos have the license
-NUUG always use on our recordings, which is
-<a href="http://creativecommons.org/licenses/by-sa/3.0/no/">Creative
-Commons Navngivelse-Del på samme vilkår 3.0 Norge</a>. Many great
-talks available. Check it out! :)</p>

+ <description><p>Today, finally, my first printed draft edition of the Norwegian
+translation of Free Culture I have been working on for the last few
+years arrived in the mail. I had to fake a cover to get the interior
+printed, and the exterior of the book look awful, but that is
+irrelevant at this point. I asked for a printed pocket book version
+to get an idea about the font sizes and paper format as well as how
+good the figures and images look in print, but also to test what the
+pocket book version would look like. After receiving the 500 page
+pocket book, it became obvious to me that that pocket book size is too
+small for this book. I believe the book is too thick, and several
+tables and figures do not look good in the size they get with that
+small page sizes. I believe I will go with the 5.5x8.5 inch size
+instead. A surprise discovery from the paper version was how bad the
+URLs look in print. They are very hard to read in the colophon page.
+The URLs are red in the PDF, but light gray on paper. I need to
+change the color of links somehow to look better. But there is a
+printed book in my hand, and it feels great. :)</p>
+
+<p>Now I only need to fix the cover, wrap up the postscript with the
+store behind the book, and collect the last corrections from the proof
+readers before the book is ready for proper printing. Cover artists
+willing to work for free and create a Creative Commons licensed vector
+file looking similar to the original is most welcome, as my skills as
+a graphics designer are mostly missing.</p>

- <title>listadmin, the quick way to moderate mailman lists - nice free software</title>

- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/listadmin__the_quick_way_to_moderate_mailman_lists___nice_free_software.html</guid>

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

+ <description><p>Typesetting a book is harder than I hoped. As the translation is
+mostly done, and a volunteer proof reader was going to check the text
+on paper, it was time this summer to focus on formatting my translated
+<a href="http://www.docbook.org/">docbook</a> based version of the
+<a href="http://free-culture.cc/">Free Culture</a> book by Lawrence
+Lessig. I've been trying to get both docboox-xsl+fop and dblatex to
+give me a good looking PDF, but in the end I went with dblatex, because
+its Debian maintainer and upstream developer were responsive and very
+helpful in solving my formatting challenges.</p>
+
+<p>Last night, I finally managed to create a PDF that no longer made
+<a href="http://www.lulu.com/">Lulu.com</a> complain after uploading,
+and I ordered a text version of the book on paper. It is lacking a
+proper book cover and is not tagged with the correct ISBN number, but
+should give me an idea what the finished book will look like.</p>
+
+<p>Instead of using Lulu, I did consider printing the book using
+<a href="http://www.createspace.com/">CreateSpace</a>, but ended up
+using Lulu because it had smaller book size options (CreateSpace seem
+to lack pocket book with extended distribution). I looked for a
+similar service in Norway, but have not seen anything so far. Please
+let me know if I am missing out on something here.</p>
+
+<p>But I still struggle to decide the book size. Should I go for
+pocket book (4.25x6.875 inches / 10.8x17.5 cm) with 556 pages, Digest
+(5.5x8.5 inches / 14x21.6 cm) with 323 pages or US Trade (6x8 inches /
+15.3x22.9 cm) with 280 pages? Fewer pager give a cheaper book, and a
+smaller book is easier to carry around. The test book I ordered was
+pocket book sized, to give me an idea how well that fit in my hand,
+but I suspect I will end up using a digest sized book in the end to
+bring the prize down further.</p>
+
+<p>My biggest challenge at the moment is making nice cover art. My
+inkscape skills are not yet up to the task of replicating the original
+cover in SVG format. I also need to figure out what to write about
+the book on the back (will most likely use the same text as the
+description on web based book stores). I would love help with this,
+if you are willing to license the art source and final version using
+the same CC license as the book. My artistic skills are not really up
+to the task.</p>
+
+<p>I plan to publish the book in both English and Norwegian and on
+paper, in PDF form as well as EPUB and MOBI format. The current
+status can as usual be found on
+<a href="https://github.com/petterreinholdtsen/free-culture-lessig">github</a>
+in the archive/ directory. So far I have spent all time on making the
+PDF version look good. Someone should probably do the same with the
+dbtoepub generated e-book. Help is definitely needed here, as I
+expect to run out of steem before I find time to improve the epub
+formatting.</p>
+
+<p>Please let me know via github if you find typos in the book or
+discover translations that should be improved. The final proof
+reading is being done right now, and I expect to publish the finished
+result in a few months.</p>

- <title>Debian Jessie, PXE and automatic firmware installation</title>
- <link>http://people.skolelinux.org/pere/blog/Debian_Jessie__PXE_and_automatic_firmware_installation.html</link>
- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Jessie__PXE_and_automatic_firmware_installation.html</guid>
- <pubDate>Fri, 17 Oct 2014 14:10:00 +0200</pubDate>
- <description><p>When PXE installing laptops with Debian, I often run into the
-problem that the WiFi card require some firmware to work properly.
-And it has been a pain to fix this using preseeding in Debian.
-Normally something more is needed. But thanks to
-<a href="https://packages.qa.debian.org/i/isenkram.html">my isenkram
-package</a> and its recent tasksel extension, it has now become easy
-to do this using simple preseeding.</p>
-
-<p>The isenkram-cli package provide tasksel tasks which will install
-firmware for the hardware found in the machine (actually, requested by
-the kernel modules for the hardware). (It can also install user space
-programs supporting the hardware detected, but that is not the focus
-of this story.)</p>
-
-<p>To get this working in the default installation, two preeseding
-values are needed. First, the isenkram-cli package must be installed
-into the target chroot (aka the hard drive) before tasksel is executed
-in the pkgsel step of the debian-installer system. This is done by
-preseeding the base-installer/includes debconf value to include the
-isenkram-cli package. The package name is next passed to debootstrap
-for installation. With the isenkram-cli package in place, tasksel
-will automatically use the isenkram tasks to detect hardware specific
-packages for the machine being installed and install them, because
-isenkram-cli contain tasksel tasks.</p>
-
-<p>Second, one need to enable the non-free APT repository, because
-most firmware unfortunately is non-free. This is done by preseeding
-the apt-mirror-setup step. This is unfortunate, but for a lot of
-hardware it is the only option in Debian.</p>
-
-<p>The end result is two lines needed in your preseeding file to get
-firmware installed automatically by the installer:</p>
-
-<p><blockquote><pre>
-base-installer base-installer/includes string isenkram-cli
-apt-mirror-setup apt-setup/non-free boolean true
-</pre></blockquote></p>
-
-<p>The current version of isenkram-cli in testing/jessie will install
-both firmware and user space packages when using this method. It also
-do not work well, so use version 0.15 or later. Installing both
-firmware and user space packages might give you a bit more than you
-want, so I decided to split the tasksel task in two, one for firmware
-and one for user space programs. The firmware task is enabled by
-default, while the one for user space programs is not. This split is
-implemented in the package currently in unstable.</p>
-
-<p>If you decide to give this a go, please let me know (via email) how
-this recipe work for you. :)</p>
-
-<p>So, I bet you are wondering, how can this work. First and
-foremost, it work because tasksel is modular, and driven by whatever
-files it find in /usr/lib/tasksel/ and /usr/share/tasksel/. So the
-isenkram-cli package place two files for tasksel to find. First there
-is the task description file (/usr/share/tasksel/descs/isenkram.desc):</p>
-
-<p><blockquote><pre>
-Task: isenkram-packages
-Section: hardware
-Description: Hardware specific packages (autodetected by isenkram)
- Based on the detected hardware various hardware specific packages are
- proposed.
-Test-new-install: show show
-Relevance: 8
-Packages: for-current-hardware
-
-Task: isenkram-firmware
-Section: hardware
-Description: Hardware specific firmware packages (autodetected by isenkram)
- Based on the detected hardware various hardware specific firmware
- packages are proposed.
-Test-new-install: mark show
-Relevance: 8
-Packages: for-current-hardware-firmware
-</pre></blockquote></p>
-
-<p>The key parts are Test-new-install which indicate how the task
-should be handled and the Packages line referencing to a script in
-/usr/lib/tasksel/packages/. The scripts use other scripts to get a
-list of packages to install. The for-current-hardware-firmware script
-look like this to list relevant firmware for the machine:
-
-<p><blockquote><pre>
-#!/bin/sh
-#
-PATH=/usr/sbin:$PATH
-export PATH
-isenkram-autoinstall-firmware -l
-</pre></blockquote></p>
-
-<p>With those two pieces in place, the firmware is installed by
-tasksel during the normal d-i run. :)</p>
-
-<p>If you want to test what tasksel will install when isenkram-cli is
-installed, run <tt>DEBIAN_PRIORITY=critical tasksel --test
---new-install</tt> to get the list of packages that tasksel would
-install.</p>
-
-<p><a href="https://wiki.debian.org/DebianEdu/">Debian Edu</a> will be
-pilots in testing this feature, as isenkram is used there now to
-install firmware, replacing the earlier scripts.</p>

+ <description><p>I'm still working on the Norwegian version of the
+<a href="http://free-culture.cc/">Free Culture book by Lawrence
+Lessig</a>, and is now working on the final typesetting and layout.
+One of the features I want to get the structure similar to the
+original book is to typeset the footnotes as endnotes in the notes
+chapter. Based on the
+<a href="https://bugs.debian.org/685063">feedback from the Debian
+maintainer and the dblatex developer</a>, I came up with this recipe I
+would like to share with you. The proposal was to create a new LaTeX
+class file and add the LaTeX code there, but this is not always
+practical, when I want to be able to replace the class using a make
+file variable. So my proposal misuses the latex.begindocument XSL
+parameter value, to get a small fragment into the correct location in
+the generated LaTeX File.</p>
+
+<p>First, decide where in the DocBook document to place the endnotes,
+and add this text there:</p>
+
+<pre>
+&lt;?latex \theendnotes ?&gt;
+</pre>
+
+<p>Next, create a xsl stylesheet file dblatex-endnotes.xsl to add the
+code needed to add the endnote instructions in the preamble of the
+generated LaTeX document, with content like this:</p>
+
+<pre>
+&lt;?xml version='1.0'?&gt;
+&lt;xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'&gt;
+ &lt;xsl:param name="latex.begindocument"&gt;
+ &lt;xsl:text&gt;
+\usepackage{endnotes}
+\let\footnote=\endnote
+\def\enoteheading{\mbox{}\par\vskip-\baselineskip }
+\begin{document}
+ &lt;/xsl:text&gt;
+ &lt;/xsl:param&gt;
+&lt;/xsl:stylesheet&gt;
+</pre>
+
+<p>Finally, load this xsl file when running dblatex, for example like
+this:</p>
+
+<pre>
+dblatex --xsl-user=dblatex-endnotes.xsl freeculture.nb.xml
+</pre>
+
+<p>The end result can be seen on github, where
+<a href="https://github.com/petterreinholdtsen/free-culture-lessig">my
+book project</a> is located.</p>

+ <description><p>I går fikk vi endelig lansert en norsk version av mySocietys
+<a href="https://www.whatdotheyknow.com/">WhatDoTheyKnow</a>.
+Tjenesten heter Mimes brønn, og ble
+<a href="http://www.nuug.no/news/NUUG_lanserer_innsynstjenesten_Mimes_Br_nn.shtml">annonsert
+av NUUG</a> via blogg, epost og twitter til NUUG-assosierte personer.
+Det har tatt noen år, men de siste dagene fikk vi endelig tid til å få
+på plass de siste bitene. Vi er to, Gorm og meg selv, som har vært
+primus motor for det hele, men vi har fått hjelp med oversettelser og
+oppsett fra mange flere. Jeg vil si tusen takk til hver og en av dem,
+og er veldig fornøyd med at vi klarte å få tjenesten opp å kjøre før
+ferietiden slo inn for fullt.</p>
+
+<p>Vi er usikker på hvor mye belastning den virtuelle maskinen der
+tjenesten kjører klarer, så vi har lansert litt i det stille og ikke
+til for mange folk for å se hvordan maskinen klarer seg over sommeren,
+før vi går mer aktivt ut og annonserer til høsten. Ta en titt, og se
+om du kanskje har et spørsmål til det offentlige som er egnet å sende
+inn via Mimes brønn.</p>
+
+<p>Hvis du lurer på hva i alle dager en slik tjenestes kan brukes til,
+anbefaler jeg deg å se
+<a href="http://beta.frikanalen.no/video/625321">TED-foredraget til
+Heather Brook</a> om hvordan hun brukte WhatDoTheyKnow til å lære
+hvordan offentlige midler ble misbrukt. Det er en inspirerende
+historie.</p>

+ <description><p>After asking the Norwegian Broadcasting Company (NRK)
+<a href="http://people.skolelinux.org/pere/blog/Hva_gj_r_at_NRK_kan_distribuere_H_264_video_uten_patentavtale_med_MPEG_LA_.html">why
+they can broadcast and stream H.264 video without an agreement with
+the MPEG LA</a>, I was wiser, but still confused. So I asked MPEG LA
+if their understanding matched that of NRK. As far as I can tell, it
+does not.</p>
+
+<p>I started by asking for more information about the various
+licensing classes and what exactly is covered by the "Internet
+Broadcast AVC Video" class that NRK pointed me at to explain why NRK
+did not need a license for streaming H.264 video:
+
+<p><blockquote>
+
+<p>According to
+<a href="http://www.mpegla.com/Lists/MPEG%20LA%20News%20List/Attachments/226/n-10-02-02.pdf">a
+MPEG LA press release dated 2010-02-02</a>, there is no charge when
+using MPEG AVC/H.264 according to the terms of "Internet Broadcast AVC
+Video". I am trying to understand exactly what the terms of "Internet
+Broadcast AVC Video" is, and wondered if you could help me. What
+exactly is covered by these terms, and what is not?</p>
+
+<p>The only source of more information I have been able to find is a
+PDF named
+<a href="http://www.mpegla.com/main/programs/avc/Documents/avcweb.pdf">AVC

+fees:</p>

+<p>Am I correct in assuming that the four categories listed is the

+
+<p>Will a web service providing H.264 encoded video content in a

+subscription is required and no payment is required from end users to
+get access to the videos, fall under the terms of the "Internet
+Broadcast AVC Video", ie no royalty for life of the AVC Patent
+Portfolio license? Does it matter if some users are subscribed to get
+access to personalized services?</p>
+
+<p>Note, this request and all answers will be published on the
+Internet.</p>
+</blockquote></p>
+
+<p>The answer came quickly from Benjamin J. Myers, Licensing Associate
+with the MPEG LA:</p>
+
+<p><blockquote>
+<p>Thank you for your message and for your interest in MPEG LA. We
+appreciate hearing from you and I will be happy to assist you.</p>
+
+<p>As you are aware, MPEG LA offers our AVC Patent Portfolio License
+which provides coverage under patents that are essential for use of
+the AVC/H.264 Standard (MPEG-4 Part 10). Specifically, coverage is
+provided for end products and video content that make use of AVC/H.264
+technology. Accordingly, the party offering such end products and
+video to End Users concludes the AVC License and is responsible for
+paying the applicable royalties.</p>
+
+<p>Regarding Internet Broadcast AVC Video, the AVC License generally
+defines such content to be video that is distributed to End Users over
+the Internet free-of-charge. Therefore, if a party offers a service
+which allows users to upload AVC/H.264 video to its website, and such
+AVC Video is delivered to End Users for free, then such video would
+receive coverage under the sublicense for Internet Broadcast AVC
+Video, which is not subject to any royalties for the life of the AVC
+License. This would also apply in the scenario where a user creates a
+free online account in order to receive a customized offering of free
+AVC Video content. In other words, as long as the End User is given
+access to or views AVC Video content at no cost to the End User, then
+no royalties would be payable under our AVC License.</p>
+
+<p>On the other hand, if End Users pay for access to AVC Video for a
+specific period of time (e.g., one month, one year, etc.), then such
+video would constitute Subscription AVC Video. In cases where AVC
+Video is delivered to End Users on a pay-per-view basis, then such
+content would constitute Title-by-Title AVC Video. If a party offers
+Subscription or Title-by-Title AVC Video to End Users, then they would
+be responsible for paying the applicable royalties you noted below.</p>
+
+<p>Finally, in the case where AVC Video is distributed for free
+through an "over-the-air, satellite and/or cable transmission", then
+such content would constitute Free Television AVC Video and would be
+subject to the applicable royalties.</p>
+
+<p>For your reference, I have attached
+<a href="http://people.skolelinux.org/pere/blog/images/2015-07-07-mpegla.pdf">a
+.pdf copy of the AVC License</a>. You will find the relevant
+sublicense information regarding AVC Video in Sections 2.2 through
+2.5, and the corresponding royalties in Section 3.1.2 through 3.1.4.
+You will also find the definitions of Title-by-Title AVC Video,
+Subscription AVC Video, Free Television AVC Video, and Internet
+Broadcast AVC Video in Section 1 of the License. Please note that the
+electronic copy is provided for informational purposes only and cannot
+be used for execution.</p>
+
+<p>I hope the above information is helpful. If you have additional
+questions or need further assistance with the AVC License, please feel
+free to contact me directly.</p>
+</blockquote></p>
+
+<p>Having a fresh copy of the license text was useful, and knowing
+that the definition of Title-by-Title required payment per title made
+me aware that my earlier understanding of that phrase had been wrong.
+But I still had a few questions:</p>
+
+<p><blockquote>
+<p>I have a small followup question. Would it be possible for me to get
+a license with MPEG LA even if there are no royalties to be paid? The
+reason I ask, is that some video related products have a copyright
+clause limiting their use without a license with MPEG LA. The clauses
+typically look similar to this:
+
+<p><blockquote>
+ This product is licensed under the AVC patent portfolio license for
+ the personal and non-commercial use of a consumer to (a) encode
+ video in compliance with the AVC standard ("AVC video") and/or (b)
+ decode AVC video that was encoded by a consumer engaged in a
+ personal and non-commercial activity and/or AVC video that was
+ obtained from a video provider licensed to provide AVC video. No
+ license is granted or shall be implied for any other use. additional
+ information may be obtained from MPEG LA L.L.C.
+</blockquote></p>
+
+<p>It is unclear to me if this clause mean that I need to enter into
+an agreement with MPEG LA to use the product in question, even if
+there are no royalties to be paid to MPEG LA. I suspect it will
+differ depending on the jurisdiction, and mine is Norway. What is
+MPEG LAs view on this?</p>
+</blockquote></p>
+
+<p>According to the answer, MPEG LA believe those using such tools for
+non-personal or commercial use need a license with them:</p>
+
+<p><blockquote>
+
+<p>With regard to the Notice to Customers, I would like to begin by
+clarifying that the Notice from Section 7.1 of the AVC License
+reads:</p>
+
+<p>THIS PRODUCT IS LICENSED UNDER THE AVC PATENT PORTFOLIO LICENSE FOR
+THE PERSONAL USE OF A CONSUMER OR OTHER USES IN WHICH IT DOES NOT
+RECEIVE REMUNERATION TO (i) ENCODE VIDEO IN COMPLIANCE WITH THE AVC
+STANDARD ("AVC VIDEO") AND/OR (ii) DECODE AVC VIDEO THAT WAS ENCODED
+BY A CONSUMER ENGAGED IN A PERSONAL ACTIVITY AND/OR WAS OBTAINED FROM
+A VIDEO PROVIDER LICENSED TO PROVIDE AVC VIDEO. NO LICENSE IS GRANTED
+OR SHALL BE IMPLIED FOR ANY OTHER USE. ADDITIONAL INFORMATION MAY BE
+OBTAINED FROM MPEG LA, L.L.C. SEE HTTP://WWW.MPEGLA.COM</p>
+
+<p>The Notice to Customers is intended to inform End Users of the
+personal usage rights (for example, to watch video content) included
+with the product they purchased, and to encourage any party using the
+product for commercial purposes to contact MPEG LA in order to become
+licensed for such use (for example, when they use an AVC Product to
+deliver Title-by-Title, Subscription, Free Television or Internet
+Broadcast AVC Video to End Users, or to re-Sell a third party's AVC
+Product as their own branded AVC Product).</p>
+
+<p>Therefore, if a party is to be licensed for its use of an AVC
+Product to Sell AVC Video on a Title-by-Title, Subscription, Free
+Television or Internet Broadcast basis, that party would need to
+conclude the AVC License, even in the case where no royalties were
+payable under the License. On the other hand, if that party (either a
+Consumer or business customer) simply uses an AVC Product for their
+own internal purposes and not for the commercial purposes referenced
+above, then such use would be included in the royalty paid for the AVC
+Products by the licensed supplier.</p>
+
+<p>Finally, I note that our AVC License provides worldwide coverage in
+countries that have AVC Patent Portfolio Patents, including
+Norway.</p>
+
+<p>I hope this clarification is helpful. If I may be of any further
+assistance, just let me know.</p>
+</blockquote></p>
+
+<p>The mentioning of Norwegian patents made me a bit confused, so I
+asked for more information:</p>
+
+<p><blockquote>
+
+<p>But one minor question at the end. If I understand you correctly,
+you state in the quote above that there are patents in the AVC Patent
+Portfolio that are valid in Norway. This make me believe I read the
+list available from &lt;URL:
+<a href="http://www.mpegla.com/main/programs/AVC/Pages/PatentList.aspx">http://www.mpegla.com/main/programs/AVC/Pages/PatentList.aspx</a>
+&gt; incorrectly, as I believed the "NO" prefix in front of patents
+were Norwegian patents, and the only one I could find under Mitsubishi
+Electric Corporation expired in 2012. Which patents are you referring
+to that are relevant for Norway?</p>
+
+</blockquote></p>
+
+<p>Again, the quick answer explained how to read the list of patents
+in that list:</p>
+
+<p><blockquote>
+
+<p>Your understanding is correct that the last AVC Patent Portfolio
+Patent in Norway expired on 21 October 2012. Therefore, where AVC
+Video is both made and Sold in Norway after that date, then no
+royalties would be payable for such AVC Video under the AVC License.
+With that said, our AVC License provides historic coverage for AVC
+Products and AVC Video that may have been manufactured or Sold before
+the last Norwegian AVC patent expired. I would also like to clarify
+that coverage is provided for the country of manufacture and the
+country of Sale that has active AVC Patent Portfolio Patents.</p>
+
+<p>Therefore, if a party offers AVC Products or AVC Video for Sale in
+a country with active AVC Patent Portfolio Patents (for example,
+Sweden, Denmark, Finland, etc.), then that party would still need
+coverage under the AVC License even if such products or video are
+initially made in a country without active AVC Patent Portfolio
+Patents (for example, Norway). Similarly, a party would need to
+conclude the AVC License if they make AVC Products or AVC Video in a
+country with active AVC Patent Portfolio Patents, but eventually Sell
+such AVC Products or AVC Video in a country without active AVC Patent
+Portfolio Patents.</p>
+</blockquote></p>
+
+<p>As far as I understand it, MPEG LA believe anyone using Adobe
+Premiere and other video related software with a H.264 distribution
+license need a license agreement with MPEG LA to use such tools for
+anything non-private or commercial, while it is OK to set up a
+Youtube-like service as long as no-one pays to get access to the
+content. I still have no clear idea how this applies to Norway, where
+none of the patents MPEG LA is licensing are valid. Will the
+copyright terms take precedence or can those terms be ignored because
+the patents are not valid in Norway?</p>

- <pubDate>Fri, 26 Sep 2014 12:20:00 +0200</pubDate>
- <description><p>The <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux
-project</a> provide a Linux solution for schools, including a
-powerful desktop with education software, a central server providing
-web pages, user database, user home directories, central login and PXE
-boot of both clients without disk and the installation to install Debian
-Edu on machines with disk (and a few other services perhaps to small
-to mention here). We in the Debian Edu team are currently working on
-the Jessie based version, trying to get everything in shape before the
-freeze, to avoid having to maintain our own package repository in the
-future. The
-<a href="https://wiki.debian.org/DebianEdu/Status/Jessie">current
-status</a> can be seen on the Debian wiki, and there is still heaps of
-work left. Some fatal problems block testing, breaking the installer,
-but it is possible to work around these to get anyway. Here is a
-recipe on how to get the installation limping along.</p>
-
-<p>First, download the test ISO via
-<a href="ftp://ftp.skolelinux.no/cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-1.iso">ftp</a>,
-<a href="http://ftp.skolelinux.no/cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-1.iso">http</a>
-or rsync (use
-ftp.skolelinux.org::cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-1.iso).
-The ISO build was broken on Tuesday, so we do not get a new ISO every
-12 hours or so, but thankfully the ISO we already got we are able to
-install with some tweaking.</p>
-
-<p>When you get to the Debian Edu profile question, go to tty2
-(use Alt-Ctrl-F2), run</p>
-
-<p><blockquote><pre>
-nano /usr/bin/edu-eatmydata-install
-</pre></blockquote></p>
-
-<p>and add 'exit 0' as the second line, disabling the eatmydata
-optimization. Return to the installation, select the profile you want
-and continue. Without this change, exim4-config will fail to install
-due to a known bug in eatmydata.</p>
-
-<p>When you get the grub question at the end, answer /dev/sda (or if
-this do not work, figure out what your correct value would be. All my
-test machines need /dev/sda, so I have no advice if it do not fit
-your need.</p>
-
-<p>If you installed a profile including a graphical desktop, log in as
-root after the initial boot from hard drive, and install the
-education-desktop-XXX metapackage. XXX can be kde, gnome, lxde, xfce
-or mate. If you want several desktop options, install more than one
-metapackage. Once this is done, reboot and you should have a working
-graphical login screen. This workaround should no longer be needed
-once the education-tasks package version 1.801 enter testing in two
-days.</p>
-
-<p>I believe the ISO build will start working on two days when the new
-tasksel package enter testing and Steve McIntyre get a chance to
-update the debian-cd git repository. The eatmydata, grub and desktop
-issues are already fixed in unstable and testing, and should show up
-on the ISO as soon as the ISO build start working again. Well the
-eatmydata optimization is really just disabled. The proper fix
-require an upload by the eatmydata maintainer applying the patch
-provided in bug <a href="https://bugs.debian.org/702711">#702711</a>.
-The rest have proper fixes in unstable.</p>
-
-<p>I hope this get you going with the installation testing, as we are
-quickly running out of time trying to get our Jessie based
-installation ready before the distribution freeze in a month.</p>
+ <title>New laptop - some more clues and ideas based on feedback</title>

+ <description><p>Several people contacted me after my previous blog post about my
+need for a new laptop, and provided very useful feedback. I wish to
+thank every one of these. Several pointed me to the possibility of
+fixing my X230, and I am already in the process of getting Lenovo to
+do so thanks to the on site, next day support contract covering the
+machine. But the battery is almost useless (I expect to replace it
+with a non-official battery) and I do not expect the machine to live
+for many more years, so it is time to plan its replacement. If I did
+not have a support contract, it was suggested to find replacement parts
+using <a href="http://www.francecrans.com/">FrancEcrans</a>, but it
+might present a language barrier as I do not understand French.</p>
+
+<p>One tip I got was to use the
+<a href="https://skinflint.co.uk/?cat=nb">Skinflint</a> web service to
+compare laptop models. It seem to have more models available than
+prisjakt.no. Another tip I got from someone I know have similar
+keyboard preferences was that the HP EliteBook 840 keyboard is not
+very good, and this matches my experience with earlier EliteBook
+keyboards I tested. Because of this, I will not consider it any further.
+
+<p>When I wrote my blog post, I was not aware of Thinkpad X250, the
+newest Thinkpad X model. The keyboard reintroduces mouse buttons
+(which is missing from the X240), and is working fairly well with
+Debian Sid/Unstable according to
+<a href="http://www.corsac.net/X250/">Corsac.net</a>. The reports I
+got on the keyboard quality are not consistent. Some say the keyboard
+is good, others say it is ok, while others say it is not very good.
+Those with experience from X41 and and X60 agree that the X250
+keyboard is not as good as those trusty old laptops, and suggest I
+keep and fix my X230 instead of upgrading, or get a used X230 to
+replace it. I'm also told that the X250 lack leds for caps lock, disk
+activity and battery status, which is very convenient on my X230. I'm
+also told that the CPU fan is running very often, making it a bit
+noisy. In any case, the X250 do not work out of the box with Debian
+Stable/Jessie, one of my requirements.</p>
+
+<p>I have also gotten a few vendor proposals, one was
+<a href="http://pro-star.com">Pro-Star</a>, another was
+<a href="http://shop.gluglug.org.uk/product/libreboot-x200/">Libreboot</a>.
+The latter look very attractive to me.</p>
+
+<p>Again, thank you all for the very useful feedback. It help a lot
+as I keep looking for a replacement.</p>
+
+<p>Update 2015-07-06: I was recommended to check out the
+<a href="">lapstore.de</a> web shop for used laptops. They got several
+different
+<a href="http://www.lapstore.de/f.php/shop/lapstore/f/411/lang/x/kw/Lenovo_ThinkPad_X_Serie/">old
+thinkpad X models</a>, and provide one year warranty.</p>

- <description><p>I use the <a href="https://sourceforge.net/p/lsdvd/">lsdvd tool</a>
-to handle my fairly large DVD collection. It is a nice command line
-tool to get details about a DVD, like title, tracks, track length,
-etc, in XML, Perl or human readable format. But lsdvd have not seen
-any new development since 2006 and had a few irritating bugs affecting
-its use with some DVDs. Upstream seemed to be dead, and in January I
-sent a small probe asking for a version control repository for the
-project, without any reply. But I use it regularly and would like to
-get <a href="https://packages.qa.debian.org/lsdvd">an updated version
-into Debian</a>. So two weeks ago I tried harder to get in touch with
-the project admin, and after getting a reply from him explaining that
-he was no longer interested in the project, I asked if I could take
-over. And yesterday, I became project admin.</p>
-
-<p>I've been in touch with a Gentoo developer and the Debian
-maintainer interested in joining forces to maintain the upstream
-project, and I hope we can get a new release out fairly quickly,
-collecting the patches spread around on the internet into on place.
-I've added the relevant Debian patches to the freshly created git
-repository, and expect the Gentoo patches to make it too. If you got
-a DVD collection and care about command line tools, check out
-<a href="https://sourceforge.net/p/lsdvd/git/ci/master/tree/">the git source</a> and join
-<a href="https://sourceforge.net/p/lsdvd/mailman/">the project mailing

+ <description><p>My primary work horse laptop is failing, and will need a
+replacement soon. The left 5 cm of the screen on my Thinkpad X230
+started flickering yesterday, and I suspect the cause is a broken
+cable, as changing the angle of the screen some times get rid of the
+flickering.</p>
+
+<p>My requirements have not really changed since I bought it, and is
+still as
+<a href="http://people.skolelinux.org/pere/blog/Thank_you_Thinkpad_X41__for_your_long_and_trustworthy_service.html">I
+described them in 2013</a>. The last time I bought a laptop, I had
+good help from
+<a href="http://www.prisjakt.no/category.php?k=353">prisjakt.no</a>
+where I could select at least a few of the requirements (mouse pin,
+wifi, weight) and go through the rest manually. Three button mouse
+and a good keyboard is not available as an option, and all the three
+laptop models proposed today (Thinkpad X240, HP EliteBook 820 G1 and
+G2) lack three mouse buttons). It is also unclear to me how good the
+keyboard on the HP EliteBooks are. I hope Lenovo have not messed up
+the keyboard, even if the quality and robustness in the X series have
+deteriorated since X41.</p>
+
+<p>I wonder how I can find a sensible laptop when none of the options
+seem sensible to me? Are there better services around to search the
+set of available laptops for features? Please send me an email if you
+have suggestions.</p>
+
+<p>Update 2015-07-23: I got a suggestion to check out the FSF
+<a href="http://www.fsf.org/resources/hw/endorsement/respects-your-freedom">list
+of endorsed hardware</a>, which is useful background information.</p>

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

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

-<a href="https://www.vegvesen.no/nvdb/api/dokumentasjon/sok">et

-gitt geografisk område. Jeg laget et enkelt shell-script for å hente
-ut antall av en gitt type innenfor området skibrua dekker, og listet
-opp navnet på typene som ble funnet. Orket ikke slå opp hvordan

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

- <title>Speeding up the Debian installer using eatmydata and dpkg-divert</title>
- <link>http://people.skolelinux.org/pere/blog/Speeding_up_the_Debian_installer_using_eatmydata_and_dpkg_divert.html</link>

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

-<td>15 min (10:25-10:40)</td>
-<td>4 min 21%</td>
-</tr>
-
-</table></p>
-
-<p>The test is done using a netinst ISO on a USB stick, so some of the
-time is spent downloading packages. The connection to the Internet
-was 100Mbit/s during testing, so downloading should not be a
-significant factor in the measurement. Download typically took a few
-seconds to a few minutes, depending on the amount of packages being
-installed.</p>
-
-<p>The speedup is implemented by using two hooks in
-<a href="https://www.debian.org/devel/debian-installer/">Debian
-Installer</a>, the pre-pkgsel.d hook to set up the diverts, and the
-finish-install.d hook to remove the divert at the end of the
-installation. I picked the pre-pkgsel.d hook instead of the
-post-base-installer.d hook because I test using an ISO without the
-eatmydata package included, and the post-base-installer.d hook in
-Debian Edu can only operate on packages included in the ISO. The
-negative effect of this is that I am unable to activate this
-optimization for the kernel installation step in d-i. If the code is
-moved to the post-base-installer.d hook, the speedup would be larger
-for the entire installation.</p>
-
-<p>I've implemented this in the
-<a href="https://packages.qa.debian.org/debian-edu-install">debian-edu-install</a>
-git repository, and plan to provide the optimization as part of the
-Debian Edu installation. If you want to test this yourself, you can
-create two files in the installer (or in an udeb). One shell script
-need do go into /usr/lib/pre-pkgsel.d/, with content like this:</p>
-
-<p><blockquote><pre>
-#!/bin/sh
-set -e
-. /usr/share/debconf/confmodule
-info() {
- logger -t my-pkgsel "info: $*"
-}
-error() {
- logger -t my-pkgsel "error: $*"
-}
-override_install() {
- apt-install eatmydata || true
- if [ -x /target/usr/bin/eatmydata ] ; then
- for bin in dpkg apt-get aptitude tasksel ; do
- file=/usr/bin/$bin
- # Test that the file exist and have not been diverted already.
- if [ -f /target$file ] ; then
- info "diverting $file using eatmydata"
- printf "#!/bin/sh\neatmydata $bin.distrib \"\$@\"\n" \

- chmod 755 /target$file.edu

+ <description><p>I en global verden med eierskap på tvers, trengs det informasjon om
+hvem som har kontrollen i selskaper og bedrifter. Og for å få tilgang
+til slik informasjon for alle som ønsker å analysere eierskap, holder
+med ikke med nasjonale databaser over eierskap, det må globale
+samledatabaser med åpne data til. Heldigvis finnes det en
+internasjonal bevegelse for å gjøre selskapsinformasjon for alle land
+offentlig tilgjengelig. En slik database heter
+<a href="http://opencorporates.com">OpenCorporates</a>, der
+informasjonen er gratis tilgjengelig med en "del på samme
+vilkår"-lisens. De samler inn selskapsinformasjon, eierskap,
+konsesjonstildelinger og lignende. De manglet ganske mye for Norge,
+da bruksvilkårene til Norsk offentlig informasjon i stor grad
+blokkerer OpenCorporates fra å samle den inn.</p>
+
+<p>Men jeg er jo involvert i
+<a href="http://www.frikanalen.no/">Frikanalen</a>, som har
+TV-konsesjon, og tenkte det kunne være fint om informasjon om alle
+mediakonsesjoner var tilgjengelig i OpenCorporates, så jeg sendte
+avgårde følgende spørsmål til Medietilsynet 2015-06-22:</p>
+
+<blockquote>
+<p>Hei. Finnes det en oversikt over enhetene som Mediatilsynet fører
+tilsyn med som åpne data? Jeg lette etter den på
+&lt;URL:<a href="http://data.norge.no/">http://data.norge.no/</a>&gt; og
+&lt;URL:<a href="http://hotell.difi.no/">http://hotell.difi.no/</a>&gt; uten å
+finne noe der, og fant heller ikke noe under
+&lt;URL:<a href="http://www.medietilsynet.no/">http://www.medietilsynet.no/</a>&gt;.</p>
+
+<p>Jeg tenker på alle som har fått kringkastingskonsesjon og alle som
+er omtalt under
+&lt;URL:<a href="http://www.medietilsynet.no/mediebildet/">http://www.medietilsynet.no/mediebildet/</a>&gt;.</p>
+
+<p>Jeg skulle gjerne hatt dette maskinlesbart, og inkludert
+organisasjonsnummer og hva slags forhold mediatilsynet har til
+organisasjonene. Tanken er å importere det i
+&lt;URL:<a href="https://opencorporates.com/">https://opencorporates.com/</a>&gt; for analyse, så det bør ikke ha
+bruksbegresninger som gjør dette umulig.</p>
+</blockquote>
+
+<p>To dager senere fikk jeg svar, med de datasettene de hadde
+tilgjengelig. Svaret fra Hanne Sekkelsten hos Medietilsynet var
+informativt og imøtekommende.</p>
+
+<blockquote>
+<p>Vi viser til din e-post av 22. juni, der du ber om å få tilsendt oversikter
+over aktører Medietilsynet fører tilsyn med.</p>
+
+<p>Medietilsynet fører tilsyn med kringkastere og audiovisuelle
+bestillingstjenester som omfattes av kringkastingsloven, og med
+eierskap i aviser, fjernsyn radio og elektroniske medier etter
+medieeierskapsloven. I tillegg vil Medietilsynet etter at
+beskyttelsesloven trer i kraft fra 1. juli ha tilsyn med en rekke nye
+aktører. Nærmere informasjon om den nye loven finnes på Medietilsynets
+nettsted, her:

-
-<p>In Debian Edu, I placed both code fragments in a separate script
-edu-eatmydata-install and call it from the pre-pkgsel.d and
-finish-install.d scripts.</p>
-
-<p>By now you might ask if this change should get into the normal
-Debian installer too? I suspect it should, but am not sure the
-current debian-installer coordinators find it useful enough. It also
-depend on the side effects of the change. I'm not aware of any, but I
-guess we will see if the change is safe after some more testing.
-Perhaps there is some package in Debian depending on sync() and
-fsync() having effect? Perhaps it should go into its own udeb, to
-allow those of us wanting to enable it to do so without affecting
-everyone.</p>

-eatmydata package in Debian will solve it.</p>
-
-<p>Update 2014-10-17: The bug mentioned above is fixed in testing and
-the optimization work again. And I have discovered that the
-dpkg-divert trick is not really needed and implemented a slightly
-simpler approach as part of the debian-edu-install package. See
-tools/edu-eatmydata-install in the source package.</p>

- <description><p>Yesterday, I had the pleasure of attending a talk with the
-<a href="http://www.nuug.no/">Norwegian Unix User Group</a> about
-<a href="http://www.nuug.no/aktiviteter/20140909-sks-keyservers/">the
-OpenPGP keyserver pool sks-keyservers.net</a>, and was very happy to
-learn that there is a large set of publicly available key servers to
-use when looking for peoples public key. So far I have used
-subkeys.pgp.net, and some times wwwkeys.nl.pgp.net when the former
-were misbehaving, but those days are ended. The servers I have used
-up until yesterday have been slow and some times unavailable. I hope
-those problems are gone now.</p>
-
-<p>Behind the round robin DNS entry of the
-<a href="https://sks-keyservers.net/">sks-keyservers.net</a> service
-there is a pool of more than 100 keyservers which are checked every
-day to ensure they are well connected and up to date. It must be
-better than what I have used so far. :)</p>
-
-<p>Yesterdays speaker told me that the service is the default
-keyserver provided by the default configuration in GnuPG, but this do
-not seem to be used in Debian. Perhaps it should?</p>
-
-<p>Anyway, I've updated my ~/.gnupg/options file to now include this
-line:</p>
-
-<p><blockquote><pre>
-keyserver pool.sks-keyservers.net
-</pre></blockquote></p>
-
-<p>With GnuPG version 2 one can also locate the keyserver using SRV
-entries in DNS. Just for fun, I did just that at work, so now every
-user of GnuPG at the University of Oslo should find a OpenGPG
-keyserver automatically should their need it:</p>
-
-<p><blockquote><pre>
-% host -t srv _pgpkey-http._tcp.uio.no
-_pgpkey-http._tcp.uio.no has SRV record 0 100 11371 pool.sks-keyservers.net.

+ <description><p>It is a bit work to figure out the ownership structure of companies
+in Norway. The information is publicly available, but one need to
+recursively look up ownership for all owners to figure out the complete
+ownership graph of a given set of companies. To save me the work in
+the future, I wrote a script to do this automatically, outputting the
+ownership structure using the Graphviz/dotty format. The data source
+is web scraping from <a href="http://www.proff.no/">Proff</a>, because
+I failed to find a useful source directly from the official keepers of
+the ownership data, <a href="http://www.brreg.no/">Brønnøysundsregistrene</a>.</p>
+
+<p>To get an ownership graph for a set of companies, fetch
+<a href="https://github.com/petterreinholdtsen/brreg-norway-ownership-graph">the code from git</a> and run it using the organisation number. I'm
+using the Norwegian newspaper Dagbladet as an example here, as its
+ownership structure is very simple:</p>
+
+<pre>
+% time ./bin/eierskap-dotty 958033540 > dagbladet.dot
+
+real 0m2.841s
+user 0m0.184s
+sys 0m0.036s
%
-</pre></blockquote></p>
-
-<p>Now if only
-<a href="http://ietfreport.isoc.org/idref/draft-shaw-openpgp-hkp/">the
-HKP lookup protocol</a> supported finding signature paths, I would be
-very happy. It can look up a given key or search for a user ID, but I
-normally do not want that, but to find a trust path from my key to
-another key. Given a user ID or key ID, I would like to find (and
-download) the keys representing a signature path from my key to the
-key in question, to be able to get a trust path between the two keys.
-This is as far as I can tell not possible today. Perhaps something
-for a future version of the protocol?</p>
+</pre>
+
+<p>The script accept several organisation numbers on the command line,
+allowing a cluster of companies to be graphed in the same image. The
+resulting dot file for the example above look like this. The edges
+are labeled with the ownership percentage, and the nodes uses the
+organisation number as their name and the name as the label:</p>
+
+<pre>
+digraph ownership {
+rankdir = LR;
+"Aller Holding A/s" -> "910119877" [label="100%"]
+"910119877" -> "998689015" [label="100%"]
+"998689015" -> "958033540" [label="99%"]
+"974530600" -> "958033540" [label="1%"]
+"958033540" [label="AS DAGBLADET"]
+"998689015" [label="Berner Media Holding AS"]
+"974530600" [label="Dagbladets Stiftelse"]
+"910119877" [label="Aller Media AS"]
+}
+</pre>
+
+<p>To view the ownership graph, run "<tt>dotty dagbladet.dot</tt>" or
+convert it to a PNG using "<tt>dot -T png dagbladet.dot >
+dagbladet.png</tt>". The result can be seen below:</p>
+
+<img src="http://people.skolelinux.org/pere/blog/images/2015-06-15-ownership-graphs-norway-dagbladet.png" width="80%">
+
+<p>Note that I suspect the "Aller Holding A/S" entry to be incorrect
+data in the official ownership register, as that name is not
+registered in the official company register for Norway. The ownership
+register is sensitive to typos and there seem to be no strict checking
+of the ownership links.</p>
+
+<p>Let me know if you improve the script or find better data sources.
+The code is licensed according to GPL 2 or newer.</p>
+
+<p>Update 2015-06-15: Since the initial post I've been told that
+"<a href="http://www.proff.dk/firma/carl-allers-etablissement-aktieselskab/københavn-v/hovedkontorer/13624518-3/">Aller
+Holding A/S</a>" is a Danish company, which explain why it did not
+have a Norwegian organisation number. I've also been told that there
+is a <a href="http://www.brreg.no/automatiske/webservices/">web
+services API available</a> from Brønnøysundsregistrene, for those
+willing to accept the terms or pay the price.</p>
