- <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>

+ <description><p>Over the years, administrating thousand of NFS mounting linux
+computers at the time, I often needed a way to detect if the machine
+was experiencing NFS hang. If you try to use <tt>df</tt> or look at a
+file or directory affected by the hang, the process (and possibly the
+shell) will hang too. So you want to be able to detect this without
+risking the detection process getting stuck too. It has not been
+obvious how to do this. When the hang has lasted a while, it is
+possible to find messages like these in dmesg:</p>
+
+<p><blockquote>
+nfs: server nfsserver not responding, still trying
+<br>nfs: server nfsserver OK
+</blockquote></p>
+
+<p>It is hard to know if the hang is still going on, and it is hard to
+be sure looking in dmesg is going to work. If there are lots of other
+messages in dmesg the lines might have rotated out of site before they
+are noticed.</p>
+
+<p>While reading through the nfs client implementation in linux kernel
+code, I came across some statistics that seem to give a way to detect
+it. The om_timeouts sunrpc value in the kernel will increase every
+time the above log entry is inserted into dmesg. And after digging a
+bit further, I discovered that this value show up in
+/proc/self/mountstats on Linux.</p>
+
+<p>The mountstats content seem to be shared between files using the
+same file system context, so it is enough to check one of the
+mountstats files to get the state of the mount point for the machine.
+I assume this will not show lazy umounted NFS points, nor NFS mount
+points in a different process context (ie with a different filesystem
+view), but that does not worry me.</p>
+
+<p>The content for a NFS mount point look similar to this:</p>
+
+<p><blockquote><pre>

+
+<p>The key number to look at is the third number in the per-op list.
+It is the number of NFS timeouts experiences per file system
+operation. Here 22 write timeouts and 5 access timeouts. If these
+numbers are increasing, I believe the machine is experiencing NFS
+hang. Unfortunately the timeout value do not start to increase right
+away. The NFS operations need to time out first, and this can take a
+while. The exact timeout value depend on the setup. For example the
+defaults for TCP and UDP mount points are quite different, and the
+timeout value is affected by the soft, hard, timeo and retrans NFS
+mount options.</p>
+
+<p>The only way I have been able to get working on Debian and RedHat
+Enterprise Linux for getting the timeout count is to peek in /proc/.
+But according to
+<ahref="http://docs.oracle.com/cd/E19253-01/816-4555/netmonitor-12/index.html">Solaris
+10 System Administration Guide: Network Services</a>, the 'nfsstat -c'
+command can be used to get these timeout values. But this do not work
+on Linux, as far as I can tell. I
+<ahref="http://bugs.debian.org/857043">asked Debian about this</a>,
+but have not seen any replies yet.</p>
+
+<p>Is there a better way to figure out if a Linux NFS client is
+experiencing NFS hangs? Is there a way to detect which processes are
+affected? Is there a way to get the NFS mount going quickly once the
+network problem causing the NFS hang has been cleared? I would very
+much welcome some clues, as we regularly run into NFS hangs.</p>

- <title>Typesetting DocBook footnotes as endnotes with dblatex</title>
- <link>http://people.skolelinux.org/pere/blog/Typesetting_DocBook_footnotes_as_endnotes_with_dblatex.html</link>
- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Typesetting_DocBook_footnotes_as_endnotes_with_dblatex.html</guid>

- <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>So the new president in the United States of America claim to be
+surprised to discover that he was wiretapped during the election
+before he was elected president. He even claim this must be illegal.
+Well, doh, if it is one thing the confirmations from Snowden
+documented, it is that the entire population in USA is wiretapped, one
+way or another. Of course the president candidates were wiretapped,
+alongside the senators, judges and the rest of the people in USA.</p>
+
+<p>Next, the Federal Bureau of Investigation ask the Department of
+Justice to go public rejecting the claims that Donald Trump was
+wiretapped illegally. I fail to see the relevance, given that I am
+sure the surveillance industry in USA believe they have all the legal
+backing they need to conduct mass surveillance on the entire
+world.</p>
+
+<p>There is even the director of the FBI stating that he never saw an
+order requesting wiretapping of Donald Trump. That is not very
+surprising, given how the FISA court work, with all its activity being
+secret. Perhaps he only heard about it?</p>
+
+<p>What I find most sad in this story is how Norwegian journalists
+present it. In a news reports the other day in the radio from the
+Norwegian National broadcasting Company (NRK), I heard the journalist
+claim that 'the FBI denies any wiretapping', while the reality is that
+'the FBI denies any illegal wiretapping'. There is a fundamental and
+important difference, and it make me sad that the journalists are
+unable to grasp it.</p>
+
+<p><strong>Update 2017-03-13:</strong> Look like
+<a href="https://theintercept.com/2017/03/13/rand-paul-is-right-nsa-routinely-monitors-americans-communications-without-warrants/">The
+Intercept report that US Senator Rand Paul confirm what I state above</a>.</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,

- <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
-Patent Portfolio License Briefing</a>, which states this about the
-fees:</p>
-
-<ul>
- <li>Where End User pays for AVC Video
- <ul>
- <li>Subscription (not limited by title) – 100,000 or fewer
- subscribers/yr = no royalty; &gt; 100,000 to 250,000 subscribers/yr =
- $25,000; &gt;250,000 to 500,000 subscribers/yr = $50,000; &gt;500,000 to
- 1M subscribers/yr = $75,000; &gt;1M subscribers/yr = $100,000</li>
-
- <li>Title-by-Title - 12 minutes or less = no royalty; &gt;12 minutes in
- length = lower of (a) 2% or (b) $0.02 per title</li>
- </ul></li>
-
- <li>Where remuneration is from other sources
- <ul>
- <li>Free Television - (a) one-time $2,500 per transmission encoder or
- (b) annual fee starting at $2,500 for &gt; 100,000 HH rising to
- maximum $10,000 for &gt;1,000,000 HH</li>
-
- <li>Internet Broadcast AVC Video (not title-by-title, not subscription)
- – no royalty for life of the AVC Patent Portfolio License</li>
- </ul></li>
-</ul>
-
-<p>Am I correct in assuming that the four categories listed is the
-categories used when selecting licensing terms, and that "Internet
-Broadcast AVC Video" is the category for things that do not fall into
-one of the other three categories? Can you point me to a good source
-explaining what is ment by "title-by-title" and "Free Television" in
-the license terms for AVC/H.264?</p>
-
-<p>Will a web service providing H.264 encoded video content in a
-"video on demand" fashing similar to Youtube and Vimeo, where no
-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>

+ <description><p>A few days ago I ordered a small batch of
+<a href="http://altusmetrum.org/ChaosKey/">the ChaosKey</a>, a small
+USB dongle for generating entropy created by Bdale Garbee and Keith
+Packard. Yesterday it arrived, and I am very happy to report that it
+work great! According to its designers, to get it to work out of the

+fine, increasing the available entropy very quickly. I wrote a small
+test oneliner to test. It first print the current entropy level,
+drain /dev/random, and then print the entropy level for five seconds.
+Here is the situation without the ChaosKey inserted:</p>
+
+<blockquote><pre>

+</pre></blockquote>
+
+<p>The entropy level increases by 3-4 every second. In such case any
+application requiring random bits (like a HTTPS enabled web server)
+will halt and wait for more entrpy. And here is the situation with
+the ChaosKey inserted:</p>
+
+<blockquote><pre>

-<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>Quite the difference. :) I bought a few more than I need, in case
+someone want to buy one here in Norway. :)</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>
+<p>Update: The dongle was presented at Debconf last year. You might
+find <a href="https://debconf16.debconf.org/talks/94/">the talk
+recording illuminating</a>. It explains exactly what the source of
+randomness is, if you are unable to spot it from the schema drawing

- <title>New laptop - some more clues and ideas based on feedback</title>

- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/New_laptop___some_more_clues_and_ideas_based_on_feedback.html</guid>
- <pubDate>Sun, 5 Jul 2015 21:40:00 +0200</pubDate>
- <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>

+<a href="http://www.ecma-international.org/publications/standards/Ecma-376.htm">ECMA-376</a>

+report use of undefined behaviour. Are there other similar tools
+available? Please send me an email if you know of any such tool.</p>

- <description><p>My primary work horse laptop is failing, and will need a

-started flickering yesterday, and I suspect the cause is a broken

-
-<p>My requirements have not really changed since I bought it, and is

-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

+<p>On Wednesday, I spent the entire day in court in Follo Tingrett
+representing <a href="https://www.nuug.no/">the member association
+NUUG</a>, alongside <a href="https://www.efn.no/">the member
+association EFN</a> and <a href="http://www.imc.no">the DNS registrar
+IMC</a>, challenging the seizure of the DNS name popcorn-time.no. It
+was interesting to sit in a court of law for the first time in my
+life. Our team can be seen in the picture above: attorney Ola
+Tellesbø, EFN board member Tom Fredrik Blenning, IMC CEO Morten Emil
+Eriksen and NUUG board member Petter Reinholdtsen.</p>
+
+<p><a href="http://www.domstol.no/no/Enkelt-domstol/follo-tingrett/Nar-gar-rettssaken/Beramming/?cid=AAAA1701301512081262234UJFBVEZZZZZEJBAvtale">The
+case at hand</a> is that the Norwegian National Authority for
+Investigation and Prosecution of Economic and Environmental Crime (aka
+Økokrim) decided on their own, to seize a DNS domain early last
+year, without following
+<a href="https://www.norid.no/no/regelverk/navnepolitikk/#link12">the
+official policy of the Norwegian DNS authority</a> which require a
+court decision. The web site in question was a site covering Popcorn

+and illegal applications. Popcorn Time is a client combining
+searching a Bittorrent directory available on the Internet with
+downloading/distribute content via Bittorrent and playing the
+downloaded content on screen. It can be used illegally if it is used
+to distribute content against the will of the right holder, but it can
+also be used legally to play a lot of content, for example the
+millions of movies
+<a href="https://archive.org/details/movies">available from the
+Internet Archive</a> or the collection
+<a href="http://vodo.net/films/">available from Vodo</a>. We created
+<a href="magnet:?xt=urn:btih:86c1802af5a667ca56d3918aecb7d3c0f7173084&dn=PresentasjonFolloTingrett.mov&tr=udp%3A%2F%2Fpublic.popcorn-tracker.org%3A6969%2Fannounce">a
+video demonstrating legally use of Popcorn Time</a> and played it in
+Court. It can of course be downloaded using Bittorrent.</p>
+
+<p>I did not quite know what to expect from a day in court. The
+government held on to their version of the story and we held on to
+ours, and I hope the judge is able to make sense of it all. We will
+know in two weeks time. Unfortunately I do not have high hopes, as
+the Government have the upper hand here with more knowledge about the
+case, better training in handling criminal law and in general higher
+standing in the courts than fairly unknown DNS registrar and member
+associations. It is expensive to be right also in Norway. So far the
+case have cost more than NOK 70 000,-. To help fund the case, NUUG
+and EFN have asked for donations, and managed to collect around NOK 25
+000,- so far. Given the presentation from the Government, I expect
+the government to appeal if the case go our way. And if the case do
+not go our way, I hope we have enough funding to appeal.</p>
+
+<p>From the other side came two people from Økokrim. On the benches,
+appearing to be part of the group from the government were two people
+from the Simonsen Vogt Wiik lawyer office, and three others I am not
+quite sure who was. Økokrim had proposed to present two witnesses
+from The Motion Picture Association, but this was rejected because
+they did not speak Norwegian and it was a bit late to bring in a
+translator, but perhaps the two from MPA were present anyway. All
+seven appeared to know each other. Good to see the case is take
+seriously.</p>
+
+<p>If you, like me, believe the courts should be involved before a DNS
+domain is hijacked by the government, or you believe the Popcorn Time
+technology have a lot of useful and legal applications, I suggest you
+too <a href="http://www.nuug.no/dns-beslag-donasjon.shtml">donate to
+the NUUG defense fund</a>. Both Bitcoin and bank transfer are
+available. If NUUG get more than we need for the legal action (very
+unlikely), the rest will be spend promoting free software, open
+standards and unix-like operating systems in Norway, so no matter what
+happens the money will be put to good use.</p>
+
+<p>If you want to lean more about the case, I recommend you check out
+<a href="https://www.nuug.no/news/tags/dns-domenebeslag/">the blog
+posts from NUUG covering the case</a>. They cover the legal arguments
+on both sides.</p>

- <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

-bestillingstjenester som omfattes av kringkastingsloven, og med

-beskyttelsesloven trer i kraft fra 1. juli ha tilsyn med en rekke nye

+ <description><p>I dag fikk jeg en skikkelig gladmelding. Bakgrunnen er at før jul
+arrangerte Nasjonalbiblioteket
+<a href="http://www.nb.no/Bibliotekutvikling/Kunnskapsorganisering/Nasjonalt-verksregister/Seminar-om-verksregister">et
+seminar om sitt knakende gode tiltak «verksregister»</a>. Eneste
+måten å melde seg på dette seminaret var å sende personopplysninger
+til Google via Google Skjemaer. Dette syntes jeg var tvilsom praksis,
+da det bør være mulig å delta på seminarer arrangert av det offentlige
+uten å måtte dele sine interesser, posisjon og andre
+personopplysninger med Google. Jeg ba derfor om innsyn via
+<a href="https://www.mimesbronn.no/">Mimes brønn</a> i
+<a href="https://www.mimesbronn.no/request/personopplysninger_til_google_sk">avtaler
+og vurderinger Nasjonalbiblioteket hadde rundt dette</a>.
+Personopplysningsloven legger klare rammer for hva som må være på
+plass før en kan be tredjeparter, spesielt i utlandet, behandle
+personopplysninger på sine vegne, så det burde eksistere grundig
+dokumentasjon før noe slikt kan bli lovlig. To jurister hos
+Nasjonalbiblioteket mente først dette var helt i orden, og at Googles
+standardavtale kunne brukes som databehandlingsavtale. Det syntes jeg
+var merkelig, men har ikke hatt kapasitet til å følge opp saken før
+for to dager siden.</p>
+
+<p>Gladnyheten i dag, som kom etter at jeg tipset Nasjonalbiblioteket
+om at Datatilsynet underkjente Googles standardavtaler som
+databehandleravtaler i 2011, er at Nasjonalbiblioteket har bestemt seg
+for å avslutte bruken av Googles Skjemaer/Apps og gå i dialog med DIFI
+for å finne bedre måter å håndtere påmeldinger i tråd med
+personopplysningsloven. Det er fantastisk å se at av og til hjelper
+det å spørre hva i alle dager det offentlige holder på med.</p>

+ <pubDate>Wed, 11 Jan 2017 06:50:00 +0100</pubDate>
+ <description><p>Jeg leste med interesse en nyhetssak hos
+<a href="http://www.digi.no/artikler/nav-avslorer-trygdemisbruk-ved-a-spore-ip-adresser/367394">digi.no</a>
+og
+<a href="https://www.nrk.no/buskerud/trygdesvindlere-avslores-av-utenlandske-ip-adresser-1.13313461">NRK</a>
+om at det ikke bare er meg, men at også NAV bedriver geolokalisering
+av IP-adresser, og at det gjøres analyse av IP-adressene til de som
+sendes inn meldekort for å se om meldekortet sendes inn fra
+utenlandske IP-adresser. Politiadvokat i Drammen, Hans Lyder Haare,
+er sitert i NRK på at «De to er jo blant annet avslørt av
+IP-adresser. At man ser at meldekortet kommer fra utlandet.»</p>
+
+<p>Jeg synes det er fint at det blir bedre kjent at IP-adresser
+knyttes til enkeltpersoner og at innsamlet informasjon brukes til å
+stedsbestemme personer også av aktører her i Norge. Jeg ser det som
+nok et argument for å bruke
+<a href="https://www.torproject.org/">Tor</a> så mye som mulig for å
+gjøre gjøre IP-lokalisering vanskeligere, slik at en kan beskytte sin
+privatsfære og unngå å dele sin fysiske plassering med
+uvedkommede.</p>

- <title>Graphing the Norwegian company ownership structure</title>
- <link>http://people.skolelinux.org/pere/blog/Graphing_the_Norwegian_company_ownership_structure.html</link>

- <pubDate>Mon, 15 Jun 2015 14:00:00 +0200</pubDate>
- <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>
-
-<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>
+<p>Jeg klarer ikke helt å se hvordan analyse av de besøkendes
+IP-adresser for å se hvem som sender inn meldekort via web fra en
+IP-adresse i utlandet kan gjøres uten å komme i strid med påstanden om
+at «ingen av opplysningene vil bli brukt til å identifisere
+enkeltpersoner». Det virker dermed for meg som at NAV bryter sine
+egen personvernerklæring, hvilket
+<a href="http://people.skolelinux.org/pere/blog/Er_lover_brutt_n_r_personvernpolicy_ikke_stemmer_med_praksis_.html">Datatilsynet
+fortalte meg i starten av desember antagelig er brudd på
+personopplysningsloven</a>.
+
+<p>I tillegg er personvernerklæringen ganske misvisende i og med at
+NAVs nettsider ikke bare forsyner NAV med personopplysninger, men i
+tillegg ber brukernes nettleser kontakte fem andre nettjenere
+(script.hotjar.com, static.hotjar.com, vars.hotjar.com,
+www.google-analytics.com og www.googletagmanager.com), slik at
+personopplysninger blir gjort tilgjengelig for selskapene Hotjar og
+Google , og alle som kan lytte på trafikken på veien (som FRA, GCHQ og
+NSA). Jeg klarer heller ikke se hvordan slikt spredning av
+personopplysninger kan være i tråd med kravene i
+personopplysningloven, eller i tråd med NAVs personvernerklæring.</p>
+
+<p>Kanskje NAV bør ta en nøye titt på sin personvernerklæring? Eller
+kanskje Datatilsynet bør gjøre det?</p>

- <description><p>Television loudness is the source of frustration for viewers
-everywhere. Some channels are very load, others are less loud, and
-ads tend to shout very high to get the attention of the viewers, and
-the viewers do not like this. This fact is well known to the TV
-channels. See for example the BBC white paper
-"<a href="http://downloads.bbc.co.uk/rd/pubs/whp/whp-pdf-files/WHP202.pdf">Terminology
-for loudness and level dBTP, LU, and all that</a>" from 2011 for a
-summary of the problem domain. To better address the need for even
-loadness, the TV channels got together several years ago to agree on a
-new way to measure loudness in digital files as one step in
-standardizing loudness. From this came the ITU-R standard BS.1770,
-"<a href="http://www.itu.int/rec/R-REC-BS.1770/en">Algorithms to
-measure audio programme loudness and true-peak audio level</a>".</p>
-
-<p>The ITU-R BS.1770 specification describe an algorithm to measure
-loadness in LUFS (Loudness Units, referenced to Full Scale). But
-having a way to measure is not enough. To get the same loudness
-across TV channels, one also need to decide which value to standardize
-on. For European TV channels, this was done in the EBU Recommondaton
-R128, "<a href="https://tech.ebu.ch/docs/r/r128.pdf">Loudness
-normalisation and permitted maximum level of audio signals</a>", which
-specifies a recommended level of -23 LUFS. In Norway, I have been
-told that NRK, TV2, MTG and SBS have decided among themselves to
-follow the R128 recommondation for playout from 2016-03-01.</p>
-
-<p>There are free software available to measure and adjust the loudness
-level using the LUFS. In Debian, I am aware of a library named
-<a href="https://tracker.debian.org/pkg/libebur128">libebur128</a>
-able to measure the loudness and since yesterday morning a new binary
-named <a href="http://bs1770gain.sourceforge.net">bs1770gain</a>
-capable of both measuring and adjusting was uploaded and is waiting
-for NEW processing. I plan to maintain the latter in Debian under the
-<a href="https://qa.debian.org/developer.php?email=pkg-multimedia-maintainers%40lists.alioth.debian.org">Debian
-multimedia</a> umbrella.</p>
-
-<p>The free software based TV channel I am involved in,
-<a href="http://www.frikanalen.no/">Frikanalen</a>, plan to follow the
-R128 recommondation ourself as soon as we can adjust the software to
-do so, and the bs1770gain tool seem like a good fit for that part of
-the puzzle to measure loudness on new video uploaded to Frikanalen.
-Personally, I plan to use bs1770gain to adjust the loudness of videos
-I upload to Frikanalen on behalf of <a href="http://www.nuug.no/">the
-NUUG member organisation</a>. The program seem to be able to measure
-the LUFS value of any media file handled by ffmpeg, but I've only
-successfully adjusted the LUFS value of WAV files. I suspect it
-should be able to adjust it for all the formats handled by ffmpeg.</p>

+It is possible to get a glimpse of this from using traceroute, but it

+<p>This show the DNS names and IP addresses of (at least some of the)
+network equipment involved in getting the data traffic from me to the
+www.stortinget.no server, and how long it took in milliseconds for a
+package to reach the equipment and return to me. Three packages are
+sent, and some times the packages do not follow the same path. This
+is shown for hop 5, where three different IP addresses replied to the
+traceroute request.</p>
+
+<p>There are many ways to measure trace routes. Other good traceroute
+implementations I use are traceroute (using ICMP packages) mtr (can do
+both ICMP, UDP and TCP) and scapy (python library with ICMP, UDP, TCP
+traceroute and a lot of other capabilities). All of them are easily
+available in <a href="https://www.debian.org/">Debian</a>.</p>
+
+<p>This time around, I wanted to know the geographic location of
+different route points, to visualize how visiting a web page spread
+information about the visit to a lot of servers around the globe. The
+background is that a web site today often will ask the browser to get
+from many servers the parts (for example HTML, JSON, fonts,
+JavaScript, CSS, video) required to display the content. This will
+leak information about the visit to those controlling these servers
+and anyone able to peek at the data traffic passing by (like your ISP,
+the ISPs backbone provider, FRA, GCHQ, NSA and others).</p>
+
+<p>Lets pick an example, the Norwegian parliament web site
+www.stortinget.no. It is read daily by all members of parliament and
+their staff, as well as political journalists, activits and many other
+citizens of Norway. A visit to the www.stortinget.no web site will
+ask your browser to contact 8 other servers: ajax.googleapis.com,
+insights.hotjar.com, script.hotjar.com, static.hotjar.com,
+stats.g.doubleclick.net, www.google-analytics.com,
+www.googletagmanager.com and www.netigate.se. I extracted this by
+asking <a href="http://phantomjs.org/">PhantomJS</a> to visit the
+Stortinget web page and tell me all the URLs PhantomJS downloaded to
+render the page (in HAR format using
+<a href="https://github.com/ariya/phantomjs/blob/master/examples/netsniff.js">their
+netsniff example</a>. I am very grateful to Gorm for showing me how
+to do this). My goal is to visualize network traces to all IP
+addresses behind these DNS names, do show where visitors personal
+information is spread when visiting the page.</p>

+
+<p>When I had a look around for options, I could not find any good
+free software tools to do this, and decided I needed my own traceroute
+wrapper outputting KML based on locations looked up using GeoIP. KML
+is easy to work with and easy to generate, and understood by several
+of the GIS tools I have available. I got good help from by NUUG
+colleague Anders Einar with this, and the result can be seen in
+<a href="https://github.com/petterreinholdtsen/kmltraceroute">my
+kmltraceroute git repository</a>. Unfortunately, the quality of the
+free GeoIP databases I could find (and the for-pay databases my
+friends had access to) is not up to the task. The IP addresses of
+central Internet infrastructure would typically be placed near the
+controlling companies main office, and not where the router is really
+located, as you can see from <a href="www.stortinget.no-geoip.kml">the
+KML file I created</a> using the GeoLite City dataset from MaxMind.

+
+<p>I also had a look at the visual traceroute graph created by
+<a href="http://www.secdev.org/projects/scapy/">the scrapy project</a>,
+showing IP network ownership (aka AS owner) for the IP address in
+question.
+<a href="http://people.skolelinux.org/pere/blog/images/2017-01-09-www.stortinget.no-scapy.svg">The
+graph display a lot of useful information about the traceroute in SVG
+format</a>, and give a good indication on who control the network
+equipment involved, but it do not include geolocation. This graph
+make it possible to see the information is made available at least for
+UNINETT, Catchcom, Stortinget, Nordunet, Google, Amazon, Telia, Level
+3 Communications and NetDNA.</p>

+<p align="center"><a href="https://geotraceroute.com/index.php?node=4&host=www.stortinget.no"><img

+
+<p>In the process, I came across the
+<a href="https://geotraceroute.com/">web service GeoTraceroute</a> by
+Salim Gasmi. Its methology of combining guesses based on DNS names,
+various location databases and finally use latecy times to rule out
+candidate locations seemed to do a very good job of guessing correct
+geolocation. But it could only do one trace at the time, did not have
+a sensor in Norway and did not make the geolocations easily available
+for postprocessing. So I contacted the developer and asked if he
+would be willing to share the code (he refused until he had time to
+clean it up), but he was interested in providing the geolocations in a
+machine readable format, and willing to set up a sensor in Norway. So
+since yesterday, it is possible to run traces from Norway in this
+service thanks to a sensor node set up by
+<a href="https://www.nuug.no/">the NUUG assosiation</a>, and get the
+trace in KML format for further processing.</p>

+<p align="center"><a href="http://people.skolelinux.org/pere/blog/images/2017-01-09-www.stortinget.no-geotraceroute-kml-join.kml"><img

+
+<p>Here we can see a lot of trafic passes Sweden on its way to
+Denmark, Germany, Holland and Ireland. Plenty of places where the
+Snowden confirmations verified the traffic is read by various actors
+without your best interest as their top priority.</p>
+
+<p>Combining KML files is trivial using a text editor, so I could loop
+over all the hosts behind the urls imported by www.stortinget.no and
+ask for the KML file from GeoTraceroute, and create a combined KML
+file with all the traces (unfortunately only one of the IP addresses
+behind the DNS name is traced this time. To get them all, one would
+have to request traces using IP number instead of DNS names from
+GeoTraceroute). That might be the next step in this project.</p>
+
+<p>Armed with these tools, I find it a lot easier to figure out where
+the IP traffic moves and who control the boxes involved in moving it.
+And every time the link crosses for example the Swedish border, we can
+be sure Swedish Signal Intelligence (FRA) is listening, as GCHQ do in
+Britain and NSA in USA and cables around the globe. (Hm, what should
+we tell them? :) Keep that in mind if you ever send anything
+unencrypted over the Internet.</p>
+
+<p>PS: KML files are drawn using
+<a href="http://ivanrublev.me/kml/">the KML viewer from Ivan
+Rublev<a/>, as it was less cluttered than the local Linux application
+Marble. There are heaps of other options too.</p>
