- <description><p>Making packages for Debian require quite a lot of attention to
-details. And one of the details is the content of the
-debian/copyright file, which should list all relevant licenses used by
-the code in the package in question, preferably in
-<a href="https://www.debian.org/doc/packaging-manuals/copyright-format/1.0/">machine
-readable DEP5 format</a>.</p>
-
-<p>For large packages with lots of contributors it is hard to write
-and update this file manually, and if you get some detail wrong, the
-package is normally rejected by the ftpmasters. So getting it right
-the first time around get the package into Debian faster, and save
-both you and the ftpmasters some work.. Today, while trying to figure
-out what was wrong with
-<a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=686447">the
-zfsonlinux copyright file</a>, I decided to spend some time on
-figuring out the options for doing this job automatically, or at least
-semi-automatically.</p>
-
-<p>Lucikly, there are at least two tools available for generating the
-file based on the code in the source package,
-<tt><a href="https://tracker.debian.org/pkg/debmake">debmake</a></tt>
-and <tt><a href="https://tracker.debian.org/pkg/cme">cme</a></tt>. I'm
-not sure which one of them came first, but both seem to be able to
-create a sensible draft file. As far as I can tell, none of them can
-be trusted to get the result just right, so the content need to be
-polished a bit before the file is OK to upload. I found the debmake
-option in
-<a href="http://goofying-with-debian.blogspot.com/2014/07/debmake-checking-source-against-dep-5.html">a
-blog posts from 2014</a>.
-
-<p>To generate using debmake, use the -cc option:
-
-<p><pre>
-debmake -cc > debian/copyright
-</pre></p>
-
-<p>Note there are some problems with python and non-ASCII names, so
-this might not be the best option.</p>
-
-<p>The cme option is based on a config parsing library, and I found
-this approach in
-<a href="https://ddumont.wordpress.com/2015/04/05/improving-creation-of-debian-copyright-file/">a
-blog post from 2015</a>. To generate using cme, use the 'update
-dpkg-copyright' option:
-
-<p><pre>
-cme update dpkg-copyright -quiet
-</pre></p>
-
-<p>This will create or update debian/copyright. The cme tool seem to
-handle UTF-8 names better than debmake.</p>
-
-<p>When the copyright file is created, I would also like some help to
-check if the file is correct. For this I found two good options,
-<tt>debmake -k</tt> and <tt>license-reconcile</tt>. The former seem
-to focus on license types and file matching, and is able to detect
-ineffective blocks in the copyright file. The latter reports missing
-copyright holders and years, but was confused by inconsistent license
-names (like CDDL vs. CDDL-1.0). I suspect it is good to use both and
-fix all issues reported by them before uploading. But I do not know
-if the tools and the ftpmasters agree on what is important to fix in a
-copyright file, so the package might still be rejected.</p>
-
-<p>The devscripts tool <tt>licensecheck</tt> deserve mentioning. It
-will read through the source and try to find all copyright statements.
-It is not comparing the result to the content of debian/copyright, but
-can be useful when verifying the content of the copyright file.</p>
-
-<p>Are you aware of better tools in Debian to create and update
-debian/copyright file. Please let me know, or blog about it on
-planet.debian.org.</p>

+ <pubDate>Wed, 7 Jun 2017 21:40:00 +0200</pubDate>
+ <description><p><em>This is a copy of
+<a href="https://lists.nuug.no/pipermail/nikita-noark/2017-June/000297.html">an
+email I posted to the nikita-noark mailing list</a>. Please follow up
+there if you would like to discuss this topic. The background is that
+we are making a free software archive system based on the Norwegian
+<a href="https://www.arkivverket.no/forvaltning-og-utvikling/regelverk-og-standarder/noark-standarden">Noark
+5 standard</a> for government archives.</em></p>
+
+<p>I've been wondering a bit lately how trusted timestamps could be
+stored in Noark 5.
+<a href="https://en.wikipedia.org/wiki/Trusted_timestamping">Trusted
+timestamps</a> can be used to verify that some information
+(document/file/checksum/metadata) have not been changed since a
+specific time in the past. This is useful to verify the integrity of
+the documents in the archive.</p>
+
+<p>Then it occured to me, perhaps the trusted timestamps could be
+stored as dokument variants (ie dokumentobjekt referered to from
+dokumentbeskrivelse) with the filename set to the hash it is
+stamping?</p>
+
+<p>Given a "dokumentbeskrivelse" with an associated "dokumentobjekt",
+a new dokumentobjekt is associated with "dokumentbeskrivelse" with the
+same attributes as the stamped dokumentobjekt except these
+attributes:</p>
+
+<ul>
+
+<li>format -> "RFC3161"
+<li>mimeType -> "application/timestamp-reply"
+<li>formatDetaljer -> "&lt;source URL for timestamp service&gt;"
+<li>filenavn -> "&lt;sjekksum&gt;.tsr"
+
+</ul>
+
+<p>This assume a service following
+<a href="https://tools.ietf.org/html/rfc3161">IETF RFC 3161</a> is
+used, which specifiy the given MIME type for replies and the .tsr file
+ending for the content of such trusted timestamp. As far as I can
+tell from the Noark 5 specifications, it is OK to have several
+variants/renderings of a dokument attached to a given
+dokumentbeskrivelse objekt. It might be stretching it a bit to make
+some of these variants represent crypto-signatures useful for
+verifying the document integrity instead of representing the dokument
+itself.</p>
+
+<p>Using the source of the service in formatDetaljer allow several
+timestamping services to be used. This is useful to spread the risk
+of key compromise over several organisations. It would only be a
+problem to trust the timestamps if all of the organisations are
+compromised.</p>
+
+<p>The following oneliner on Linux can be used to generate the tsr
+file. $input is the path to the file to checksum, and $sha256 is the
+SHA-256 checksum of the file (ie the "<sjekksum>.tsr" value mentioned
+above).</p>
+
+<p><blockquote><pre>
+openssl ts -query -data "$inputfile" -cert -sha256 -no_nonce \
+ | curl -s -H "Content-Type: application/timestamp-query" \
+ --data-binary "@-" http://zeitstempel.dfn.de > $sha256.tsr
+</pre></blockquote></p>
+
+<p>To verify the timestamp, you first need to download the public key
+of the trusted timestamp service, for example using this command:</p>
+
+<p><blockquote><pre>
+wget -O ca-cert.txt \
+ https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt
+</pre></blockquote></p>
+
+<p>Note, the public key should be stored alongside the timestamps in
+the archive to make sure it is also available 100 years from now. It
+is probably a good idea to standardise how and were to store such
+public keys, to make it easier to find for those trying to verify
+documents 100 or 1000 years from now. :)</p>
+
+<p>The verification itself is a simple openssl command:</p>
+
+<p><blockquote><pre>
+openssl ts -verify -data $inputfile -in $sha256.tsr \
+ -CAfile ca-cert.txt -text
+</pre></blockquote></p>
+
+<p>Is there any reason this approach would not work? Is it somehow against
+the Noark 5 specification?</p>

- <description><p>The <a href="https://wiki.debian.org/DEP-11">appstream system</a>
-is taking shape in Debian, and one provided feature is a very
-convenient way to tell you which package to install to make a given
-firmware file available when the kernel is looking for it. This can
-be done using apt-file too, but that is for someone else to blog
-about. :)</p>
-
-<p>Here is a small recipe to find the package with a given firmware
-file, in this example I am looking for ctfw-3.2.3.0.bin, randomly
-picked from the set of firmware announced using appstream in Debian
-unstable. In general you would be looking for the firmware requested
-by the kernel during kernel module loading. To find the package
-providing the example file, do like this:</p>

+melder i dag</a> om feil i eksamensoppgavene for eksamen i politikk og
+menneskerettigheter, der teksten i bokmåls og nynorskutgaven ikke var
+like. Oppgaveteksten er gjengitt i artikkelen, og jeg ble nysgjerring
+på om den fri oversetterløsningen
+<a href="https://www.apertium.org/">Apertium</a> ville gjort en bedre
+jobb enn Utdanningsdirektoratet. Det kan se slik ut.</p>
+
+<p>Her er bokmålsoppgaven fra eksamenen:</p>
-<blockquote><pre>
-% apt install appstream
-[...]
-% apt update
-[...]
-% appstreamcli what-provides firmware:runtime ctfw-3.2.3.0.bin | \
- awk '/Package:/ {print $2}'
-firmware-qlogic
-%
-</pre></blockquote>
+<blockquote>
+<p>Drøft utfordringene knyttet til nasjonalstatenes og andre aktørers
+rolle og muligheter til å håndtere internasjonale utfordringer, som
+for eksempel flykningekrisen.</p>
-<p>See <a href="https://wiki.debian.org/AppStream/Guidelines">the
-appstream wiki</a> page to learn how to embed the package metadata in
-a way appstream can use.</p>
+<p>Vedlegge er eksempler på tekster som kan gi relevante perspektiver

+<ol>
+<li>Flykningeregnskapet 2016, UNHCR og IDMC
+<li>«Grenseløst Europa for fall» A-Magasinet, 26. november 2015
+</ol>
-<p>This same approach can be used to find any package supporting a
-given MIME type. This is very useful when you get a file you do not
-know how to handle. First find the mime type using <tt>file
---mime-type</tt>, and next look up the package providing support for
-it. Lets say you got an SVG file. Its MIME type is image/svg+xml,
-and you can find all packages handling this type like this:</p>
+</blockquote>
-<blockquote><pre>
-% apt install appstream
-[...]
-% apt update

+<p>Dette oversetter Apertium slik:</p>
-<p>I believe the MIME types are fetched from the desktop file for
-packages providing appstream metadata.</p>
+<blockquote>
+<p>Drøft utfordringane knytte til nasjonalstatane sine og rolla til
+andre aktørar og høve til å handtera internasjonale utfordringar, som
+til dømes *flykningekrisen.</p>
+
+<p>Vedleggja er døme på tekster som kan gje relevante perspektiv på
+temaet:</p>
+
+<ol>
+<li>*Flykningeregnskapet 2016, *UNHCR og *IDMC</li>
+<li>«*Grenseløst Europa for fall» A-Magasinet, 26. november 2015</li>
+</ol>
+
+</blockquote>
+
+<p>Ord som ikke ble forstått er markert med stjerne (*), og trenger
+ekstra språksjekk. Men ingen ord er forsvunnet, slik det var i
+oppgaven elevene fikk presentert på eksamen. Jeg mistenker dog at
+"andre aktørers rolle og muligheter til ..." burde vært oversatt til
+"rolla til andre aktørar og deira høve til ..." eller noe slikt, men
+det er kanskje flisespikking. Det understreker vel bare at det alltid
+trengs korrekturlesning etter automatisk oversettelse.</p>

- <description><p>Most people seem not to realise that every time they walk around
-with the computerised radio beacon known as a mobile phone their
-position is tracked by the phone company and often stored for a long
-time (like every time a SMS is received or sent). And if their
-computerised radio beacon is capable of running programs (often called
-mobile apps) downloaded from the Internet, these programs are often
-also capable of tracking their location (if the app requested access
-during installation). And when these programs send out information to
-central collection points, the location is often included, unless
-extra care is taken to not send the location. The provided
-information is used by several entities, for good and bad (what is
-good and bad, depend on your point of view). What is certain, is that
-the private sphere and the right to free movement is challenged and
-perhaps even eradicated for those announcing their location this way,
-when they share their whereabouts with private and public
-entities.</p>
-
-<p align="center"><img width="70%" src="http://people.skolelinux.org/pere/blog/images/2016-01-24-nice-creepy-desktop-window.png"></p>
-
-<p>The phone company logs provide a register of locations to check out
-when one want to figure out what the tracked person was doing. It is
-unavailable for most of us, but provided to selected government
-officials, company staff, those illegally buying information from
-unfaithful servants and crackers stealing the information. But the
-public information can be collected and analysed, and a free software
-tool to do so is called
-<a href="http://www.geocreepy.com/">Creepy or Cree.py</a>. I
-discovered it when I read
-<a href="http://www.aftenposten.no/kultur/Slik-kan-du-bli-overvaket-pa-Twitter-og-Instagram-uten-a-ane-det-7787884.html">an
-article about Creepy</a> in the Norwegian newspaper Aftenposten i
-November 2014, and decided to check if it was available in Debian.
-The python program was in Debian, but
-<a href="https://tracker.debian.org/pkg/creepy">the version in
-Debian</a> was completely broken and practically unmaintained. I
-uploaded a new version which did not work quite right, but did not
-have time to fix it then. This Christmas I decided to finally try to
-get Creepy operational in Debian. Now a fixed version is available in
-Debian unstable and testing, and almost all Debian specific patches
-are now included
-<a href="https://github.com/jkakavas/creepy">upstream</a>.</p>
-
-<p>The Creepy program visualises geolocation information fetched from
-Twitter, Instagram, Flickr and Google+, and allow one to get a
-complete picture of every social media message posted recently in a
-given area, or track the movement of a given individual across all
-these services. Earlier it was possible to use the search API of at
-least some of these services without identifying oneself, but these
-days it is impossible. This mean that to use Creepy, you need to
-configure it to log in as yourself on these services, and provide
-information to them about your search interests. This should be taken
-into account when using Creepy, as it will also share information
-about yourself with the services.</p>
-
-<p>The picture above show the twitter messages sent from (or at least
-geotagged with a position from) the city centre of Oslo, the capital
-of Norway. One useful way to use Creepy is to first look at
-information tagged with an area of interest, and next look at all the
-information provided by one or more individuals who was in the area.
-I tested it by checking out which celebrity provide their location in
-twitter messages by checkout out who sent twitter messages near a
-Norwegian TV station, and next could track their position over time,
-making it possible to locate their home and work place, among other
-things. A similar technique have been
-<a href="http://www.buzzfeed.com/maxseddon/does-this-soldiers-instagram-account-prove-russia-is-covertl">used
-to locate Russian soldiers in Ukraine</a>, and it is both a powerful
-tool to discover lying governments, and a useful tool to help people
-understand the value of the private information they provide to the
-public.</p>
-
-<p>The package is not trivial to backport to Debian Stable/Jessie, as
-it depend on several python modules currently missing in Jessie (at
-least python-instagram, python-flickrapi and
-python-requests-toolbelt).</p>
-
-<p>(I have uploaded
-<a href="https://screenshots.debian.net/package/creepy">the image to
-screenshots.debian.net</a> and licensed it under the same terms as the
-Creepy program in Debian.)</p>

+ <description><p>I disse dager, med frist 1. mai, har Riksarkivaren ute en høring på
+sin forskrift. Som en kan se er det ikke mye tid igjen før fristen
+som går ut på søndag. Denne forskriften er det som lister opp hvilke
+formater det er greit å arkivere i
+<a href="http://www.arkivverket.no/arkivverket/Offentleg-forvalting/Noark/Noark-5">Noark
+5-løsninger</a> i Norge.</p>
+
+<p>Jeg fant høringsdokumentene hos
+<a href="https://www.arkivrad.no/aktuelt/riksarkivarens-forskrift-pa-horing">Norsk
+Arkivråd</a> etter å ha blitt tipset på epostlisten til
+<a href="https://github.com/hiOA-ABI/nikita-noark5-core">fri
+programvareprosjektet Nikita Noark5-Core</a>, som lager et Noark 5
+Tjenestegresesnitt. Jeg er involvert i Nikita-prosjektet og takket
+være min interesse for tjenestegrensesnittsprosjektet har jeg lest en
+god del Noark 5-relaterte dokumenter, og til min overraskelse oppdaget
+at standard epost ikke er på listen over godkjente formater som kan
+arkiveres. Høringen med frist søndag er en glimrende mulighet til å
+forsøke å gjøre noe med det. Jeg holder på med
+<a href="https://github.com/petterreinholdtsen/noark5-tester/blob/master/docs/hoering-arkivforskrift.tex">egen
+høringsuttalelse</a>, og lurer på om andre er interessert i å støtte
+forslaget om å tillate arkivering av epost som epost i arkivet.</p>
+
+<p>Er du igang med å skrive egen høringsuttalelse allerede? I så fall
+kan du jo vurdere å ta med en formulering om epost-lagring. Jeg tror
+ikke det trengs så mye. Her et kort forslag til tekst:</p>
+
+<p><blockquote>
+
+ <p>Viser til høring sendt ut 2017-02-17 (Riksarkivarens referanse
+ 2016/9840 HELHJO), og tillater oss å sende inn noen innspill om
+ revisjon av Forskrift om utfyllende tekniske og arkivfaglige
+ bestemmelser om behandling av offentlige arkiver (Riksarkivarens
+ forskrift).</p>
+
+ <p>Svært mye av vår kommuikasjon foregår i dag på e-post. Vi
+ foreslår derfor at Internett-e-post, slik det er beskrevet i IETF
+ RFC 5322,
+ <a href="https://tools.ietf.org/html/rfc5322">https://tools.ietf.org/html/rfc5322</a>. bør
+ inn som godkjent dokumentformat. Vi foreslår at forskriftens
+ oversikt over godkjente dokumentformater ved innlevering i § 5-16
+ endres til å ta med Internett-e-post.</p>
+
+</blockquote></p>
+
+<p>Som del av arbeidet med tjenestegrensesnitt har vi testet hvordan
+epost kan lagres i en Noark 5-struktur, og holder på å skrive et
+forslag om hvordan dette kan gjøres som vil bli sendt over til
+arkivverket så snart det er ferdig. De som er interesserte kan
+<a href="https://github.com/petterreinholdtsen/noark5-tester/blob/master/docs/epostlagring.md">følge
+fremdriften på web</a>.</p>

- <description><p>During his DebConf15 keynote, Jacob Appelbaum
-<a href="https://summit.debconf.org/debconf15/meeting/331/what-is-to-be-done/">observed
-that those listening on the Internet lines would have good reason to
-believe a computer have a given security hole</a> if it download a
-security fix from a Debian mirror. This is a good reason to always
-use encrypted connections to the Debian mirror, to make sure those
-listening do not know which IP address to attack. In August, Richard
-Hartmann observed that encryption was not enough, when it was possible
-to interfere download size to security patches or the fact that
-download took place shortly after a security fix was released, and
-<a href="http://richardhartmann.de/blog/posts/2015/08/24-Tor-enabled_Debian_mirror/">proposed
-to always use Tor to download packages from the Debian mirror</a>. He
-was not the first to propose this, as the
-<tt><a href="https://tracker.debian.org/pkg/apt-transport-tor">apt-transport-tor</a></tt>
-package by Tim Retout already existed to make it easy to convince apt
-to use <a href="https://www.torproject.org/">Tor</a>, but I was not
-aware of that package when I read the blog post from Richard.</p>
-
-<p>Richard discussed the idea with Peter Palfrader, one of the Debian
-sysadmins, and he set up a Tor hidden service on one of the central
-Debian mirrors using the address vwakviie2ienjx6t.onion, thus making
-it possible to download packages directly between two tor nodes,
-making sure the network traffic always were encrypted.</p>
-
-<p>Here is a short recipe for enabling this on your machine, by
-installing <tt>apt-transport-tor</tt> and replacing http and https
-urls with tor+http and tor+https, and using the hidden service instead
-of the official Debian mirror site. I recommend installing
-<tt>etckeeper</tt> before you start to have a history of the changes
-done in /etc/.</p>

-<p>If you have more sources listed in /etc/apt/sources.list.d/, run
-the sed commands for these too. The sed command is assuming your are
-using the ftp.debian.org Debian mirror. Adjust the command (or just
-edit the file manually) to match your mirror.</p>
-
-<p>This work in Debian Jessie and later. Note that tools like
-<tt>apt-file</tt> only recently started using the apt transport
-system, and do not work with these tor+http URLs. For
-<tt>apt-file</tt> you need the version currently in experimental,
-which need a recent apt version currently only in unstable. So if you
-need a working <tt>apt-file</tt>, this is not for you.</p>
-
-<p>Another advantage from this change is that your machine will start
-using Tor regularly and at fairly random intervals (every time you
-update the package lists or upgrade or install a new package), thus
-masking other Tor traffic done from the same machine. Using Tor will
-become normal for the machine in question.</p>
-
-<p>On <a href="https://wiki.debian.org/FreedomBox">Freedombox</a>, APT
-is set up by default to use <tt>apt-transport-tor</tt> when Tor is
-enabled. It would be great if it was the default on any Debian
-system.</p>
+<p>Her kan en se at tjenesten gir «404 Not Found» for curl i
+standardoppsettet, mens den gir «200 OK» hvis curl hevder å være Opera
+versjon 12.0. Offentlig elektronisk postjournal startet blokkeringen
+2017-03-02.</p>
+
+<p>Blokkeringen vil gjøre det litt vanskeligere å maskinelt hente
+informasjon fra oep.no. Kan blokkeringen være gjort for å hindre
+automatisert innsamling av informasjon fra OEP, slik Pressens
+Offentlighetsutvalg gjorde for å dokumentere hvordan departementene
+hindrer innsyn i
+<a href="http://presse.no/dette-mener-np/undergraver-offentlighetsloven/">rapporten
+«Slik hindrer departementer innsyn» som ble publiserte i januar
+2017</a>. Det virker usannsynlig, da det jo er trivielt å bytte
+User-Agent til noe nytt.</p>
+
+<p>Finnes det juridisk grunnlag for det offentlige å diskriminere
+webklienter slik det gjøres her? Der tilgang gis eller ikke alt etter
+hva klienten sier at den heter? Da OEP eies av DIFI og driftes av
+Basefarm, finnes det kanskje noen dokumenter sendt mellom disse to

+ <description><p>The <a href="https://github.com/hiOA-ABI/nikita-noark5-core">Nikita
+Noark 5 core project</a> is implementing the Norwegian standard for
+keeping an electronic archive of government documents.
+<a href="http://www.arkivverket.no/arkivverket/Offentlig-forvaltning/Noark/Noark-5/English-version">The
+Noark 5 standard</a> document the requirement for data systems used by
+the archives in the Norwegian government, and the Noark 5 web interface
+specification document a REST web service for storing, searching and
+retrieving documents and metadata in such archive. I've been involved
+in the project since a few weeks before Christmas, when the Norwegian
+Unix User Group
+<a href="https://www.nuug.no/news/NOARK5_kjerne_som_fri_programvare_f_r_epostliste_hos_NUUG.shtml">announced
+it supported the project</a>. I believe this is an important project,
+and hope it can make it possible for the government archives in the
+future to use free software to keep the archives we citizens depend
+on. But as I do not hold such archive myself, personally my first use
+case is to store and analyse public mail journal metadata published
+from the government. I find it useful to have a clear use case in
+mind when developing, to make sure the system scratches one of my
+itches.</p>
+
+<p>If you would like to help make sure there is a free software
+alternatives for the archives, please join our IRC channel
+(<a href="irc://irc.freenode.net/%23nikita"">#nikita on
+irc.freenode.net</a>) and
+<a href="https://lists.nuug.no/mailman/listinfo/nikita-noark">the
+project mailing list</a>.</p>
+
+<p>When I got involved, the web service could store metadata about
+documents. But a few weeks ago, a new milestone was reached when it
+became possible to store full text documents too. Yesterday, I
+completed an implementation of a command line tool
+<tt>archive-pdf</tt> to upload a PDF file to the archive using this
+API. The tool is very simple at the moment, and find existing
+<a href="https://en.wikipedia.org/wiki/Fonds">fonds</a>, series and
+files while asking the user to select which one to use if more than
+one exist. Once a file is identified, the PDF is associated with the
+file and uploaded, using the title extracted from the PDF itself. The
+process is fairly similar to visiting the archive, opening a cabinet,
+locating a file and storing a piece of paper in the archive. Here is
+a test run directly after populating the database with test data using
+our API tester:</p>
+
+<p><blockquote><pre>
+~/src//noark5-tester$ ./archive-pdf mangelmelding/mangler.pdf
+using arkiv: Title of the test fonds created 2017-03-18T23:49:32.103446
+using arkivdel: Title of the test series created 2017-03-18T23:49:32.103446

+ File 2017/1: Title of the test case file created 2017-03-18T23:49:32.103446
+~/src//noark5-tester$
+</pre></blockquote></p>
+
+<p>You can see here how the fonds (arkiv) and serie (arkivdel) only had
+one option, while the user need to choose which file (mappe) to use
+among the two created by the API tester. The <tt>archive-pdf</tt>
+tool can be found in the git repository for the API tester.</p>
+
+<p>In the project, I have been mostly working on
+<a href="https://github.com/petterreinholdtsen/noark5-tester">the API
+tester</a> so far, while getting to know the code base. The API
+tester currently use
+<a href="https://en.wikipedia.org/wiki/HATEOAS">the HATEOAS links</a>
+to traverse the entire exposed service API and verify that the exposed
+operations and objects match the specification, as well as trying to
+create objects holding metadata and uploading a simple XML file to
+store. The tester has proved very useful for finding flaws in our
+implementation, as well as flaws in the reference site and the
+specification.</p>
+
+<p>The test document I uploaded is a summary of all the specification
+defects we have collected so far while implementing the web service.
+There are several unclear and conflicting parts of the specification,
+and we have
+<a href="https://github.com/petterreinholdtsen/noark5-tester/tree/master/mangelmelding">started
+writing down</a> the questions we get from implementing it. We use a
+format inspired by how <a href="http://www.opengroup.org/austin/">The
+Austin Group</a> collect defect reports for the POSIX standard with
+<a href="http://www.opengroup.org/austin/mantis.html">their
+instructions for the MANTIS defect tracker system</a>, in lack of an official way to structure defect reports for Noark 5 (our first submitted defect report was a <a href="https://github.com/petterreinholdtsen/noark5-tester/blob/master/mangelmelding/sendt/2017-03-15-mangel-prosess.md">request for a procedure for submitting defect reports</a> :).
+
+<p>The Nikita project is implemented using Java and Spring, and is
+fairly easy to get up and running using Docker containers for those
+that want to test the current code base. The API tester is
+implemented in Python.</p>

- <description><p>When I was a kid, we used to collect "car numbers", as we used to
-call the car license plate numbers in those days. I would write the
-numbers down in my little book and compare notes with the other kids
-to see how many region codes we had seen and if we had seen some
-exotic or special region codes and numbers. It was a fun game to pass
-time, as we kids have plenty of it.</p>
-
-<p>A few days I came across
-<a href="https://github.com/openalpr/openalpr">the OpenALPR
-project</a>, a free software project to automatically discover and
-report license plates in images and video streams, and provide the
-"car numbers" in a machine readable format. I've been looking for
-such system for a while now, because I believe it is a bad idea that the
-<a href="https://en.wikipedia.org/wiki/Automatic_number_plate_recognition">automatic
-number plate recognition</a> tool only is available in the hands of
-the powerful, and want it to be available also for the powerless to
-even the score when it comes to surveillance and sousveillance. I
-discovered the developer
-<a href="https://bugs.debian.org/747509">wanted to get the tool into
-Debian</a>, and as I too wanted it to be in Debian, I volunteered to
-help him get it into shape to get the package uploaded into the Debian
-archive.</p>
-
-<p>Today we finally managed to get the package into shape and uploaded
-it into Debian, where it currently
-<a href="https://ftp-master.debian.org//new/openalpr_2.2.1-1.html">waits
-in the NEW queue</a> for review by the Debian ftpmasters.</p>
-
-<p>I guess you are wondering why on earth such tool would be useful
-for the common folks, ie those not running a large government
-surveillance system? Well, I plan to put it in a computer on my bike
-and in my car, tracking the cars nearby and allowing me to be notified
-when number plates on my watch list are discovered. Another use case
-was suggested by a friend of mine, who wanted to set it up at his home
-to open the car port automatically when it discovered the plate on his
-car. When I mentioned it perhaps was a bit foolhardy to allow anyone
-capable of placing his license plate number of a piece of cardboard to
-open his car port, men replied that it was always unlocked anyway. I
-guess for such use case it make sense. I am sure there are other use
-cases too, for those with imagination and a vision.</p>
-
-<p>If you want to build your own version of the Debian package, check
-out the upstream git source and symlink ./distros/debian to ./debian/
-before running "debuild" to build the source. Or wait a bit until the
-package show up in unstable.</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>

- <description><p>Around three years ago, I created
-<a href="http://packages.qa.debian.org/isenkram">the isenkram
-system</a> to get a more practical solution in Debian for handing
-hardware related packages. A GUI system in the isenkram package will
-present a pop-up dialog when some hardware dongle supported by
-relevant packages in Debian is inserted into the machine. The same
-lookup mechanism to detect packages is available as command line
-tools in the isenkram-cli package. In addition to mapping hardware,
-it will also map kernel firmware files to packages and make it easy to
-install needed firmware packages automatically. The key for this
-system to work is a good way to map hardware to packages, in other
-words, allow packages to announce what hardware they will work
-with.</p>
-
-<p>I started by providing data files in the isenkram source, and
-adding code to download the latest version of these data files at run
-time, to ensure every user had the most up to date mapping available.
-I also added support for storing the mapping in the Packages file in
-the apt repositories, but did not push this approach because while I
-was trying to figure out how to best store hardware/package mappings,
-<a href="http://www.freedesktop.org/software/appstream/docs/">the
-appstream system</a> was announced. I got in touch and suggested to
-add the hardware mapping into that data set to be able to use
-appstream as a data source, and this was accepted at least for the
-Debian version of appstream.</p>
-
-<p>A few days ago using appstream in Debian for this became possible,
-and today I uploaded a new version 0.20 of isenkram adding support for
-appstream as a data source for mapping hardware to packages. The only
-package so far using appstream to announce its hardware support is my
-pymissile package. I got help from Matthias Klumpp with figuring out
-how do add the required
-<a href="https://appstream.debian.org/html/sid/main/metainfo/pymissile.html">metadata
-in pymissile</a>. I added a file debian/pymissile.metainfo.xml with
-this content:</p>
-
-<blockquote><pre>
-&lt;?xml version="1.0" encoding="UTF-8"?&gt;
-&lt;component&gt;
- &lt;id&gt;pymissile&lt;/id&gt;
- &lt;metadata_license&gt;MIT&lt;/metadata_license&gt;
- &lt;name&gt;pymissile&lt;/name&gt;
- &lt;summary&gt;Control original Striker USB Missile Launcher&lt;/summary&gt;
- &lt;description&gt;
- &lt;p&gt;
- Pymissile provides a curses interface to control an original
- Marks and Spencer / Striker USB Missile Launcher, as well as a
- motion control script to allow a webcamera to control the
- launcher.
- &lt;/p&gt;
- &lt;/description&gt;
- &lt;provides&gt;
- &lt;modalias&gt;usb:v1130p0202d*&lt;/modalias&gt;
- &lt;/provides&gt;
-&lt;/component&gt;
-</pre></blockquote>
-
-<p>The key for isenkram is the component/provides/modalias value,
-which is a glob style match rule for hardware specific strings
-(modalias strings) provided by the Linux kernel. In this case, it
-will map to all USB devices with vendor code 1130 and product code
-0202.</p>
-
-<p>Note, it is important that the license of all the metadata files
-are compatible to have permissions to aggregate them into archive wide
-appstream files. Matthias suggested to use MIT or BSD licenses for
-these files. A challenge is figuring out a good id for the data, as
-it is supposed to be globally unique and shared across distributions
-(in other words, best to coordinate with upstream what to use). But
-it can be changed later or, so we went with the package name as
-upstream for this project is dormant.</p>
-
-<p>To get the metadata file installed in the correct location for the
-mirror update scripts to pick it up and include its content the
-appstream data source, the file must be installed in the binary
-package under /usr/share/appdata/. I did this by adding the following
-line to debian/pymissile.install:</p>
-
-<blockquote><pre>
-debian/pymissile.metainfo.xml usr/share/appdata
-</pre></blockquote>
-
-<p>With that in place, the command line tool isenkram-lookup will list
-all packages useful on the current computer automatically, and the GUI
-pop-up handler will propose to install the package not already
-installed if a hardware dongle is inserted into the machine in
-question.</p>
-
-<p>Details of the modalias field in appstream is available from the
-<a href="https://wiki.debian.org/DEP-11">DEP-11</a> proposal.</p>
-
-<p>To locate the modalias values of all hardware present in a machine,
-try running this command on the command line:</p>
-
-<blockquote><pre>
-cat $(find /sys/devices/|grep modalias)
-</pre></blockquote>

+ <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>
+

-<a href="https://github.com/petterreinholdtsen/free-culture-lessig/">github</a>.</strong></p>
-
-<p>Jeg ble gledelig overrasket i dag da jeg oppdaget at boken jeg har
-gitt ut
-<a href="https://www.amazon.com/Fri-kultur-Norwegian-Lawrence-Lessig/dp/8269018236/">hadde
-dukket opp i Amazon</a>. Jeg hadde trodd det skulle ta lenger tid, da
-jeg fikk beskjed om at det skulle ta seks til åtte uker.
-Amazonoppføringen er et resultat av at jeg for noen uker siden
-diskuterte prissetting og håndtering av profitt med forfatteren. Det
-måtte avklares da bruksvilkårene til boken har krav om
-ikke-kommersiell bruk. Vi ble enige om at overskuddet fra salg av
-boken skal sendes til
-<a href="https://creativecommons.org/">Creative Commons-stiftelsen</a>.
-Med det på plass kunne jeg be
-<a href="https://www.lulu.com/shop/lawrence-lessig/fri-kultur/paperback/product-22441576.html">lulu.com</a>
-om å gi boken «utvidet» distribusjon. Årsaken til at
-bokhandeldistribusjon var litt utfordrende er at bokhandlere krever
-mulighet for profitt på bøkene de selger (selvfølgelig), og dermed
-måtte de få lov til å selge til høyere pris enn lulu.com. I tillegg
-er det krav om samme pris på lulu.com og i bokhandlene, dermed blir
-prisen økt også hos lulu.com. Hva skulle jeg gjøre med den profitten
-uten å bryte med klausulen om ikkekommersiell? Løsningen var å gi
-bort profitten til CC-stiftelsen. Prisen på boken ble nesten
-tredoblet, til $19.99 (ca. 160,-) pluss frakt, men synligheten øker
-betraktelig når den kan finnes i katalogene til store nettbokhandlere.
-Det betyr at hvis du allerede har kjøpt boken har du fått den veldig
-billig, og kjøper du den nå, får du den fortsatt billig samt donerer i
-tillegg noen tiere til fremme av Creative Commons.</p>
-
-<p>Mens jeg var i gang med å titte etter informasjon om boken
-oppdaget jeg at den også var dukket opp på
-<a href="https://books.google.no/books?id=uKUGCwAAQBAJ">Google
-Books</a>, der en kan lese den på web. PDF-utgaven har ennå ikke
-dukket opp hos <a href="https://www.nb.no/">Nasjonalbiblioteket</a>,
-men det regner jeg med kommer på plass i løpet av noen uker. Boken er
-heller ikke dukket opp hos
-<a href="https://www.barnesandnoble.com/">Barnes & Noble</a> ennå, men
-jeg antar det bare er et tidsspørsmål før dette er på plass.</p>
-
-<p>Boken er dessverre ikke tilgjengelig fra norske bokhandlere, og
-kommer neppe til å bli det med det første. Årsaken er at for å få det
-til måtte jeg personlig håndtere bestilling av bøker, hvilket jeg ikke
-er interessert i å bruke tid på. Jeg kunne betalt ca 2000,- til
-<a href="http://www.bokbasen.no/">den norske bokbasen</a>, en felles
-database over bøker tilgjengelig for norske bokhandlere, for å få en
-oppføring der, men da måtte jeg tatt imot bestillinger på epost og
-sendt ut bøker selv. Det ville krevd at jeg var klar til å
-sende ut bøker på kort varsel, dvs. holdt meg med ekstra bøker,
-konvolutter og frimerker. Bokbasen har visst ikke opplegg for å be
-bokhandlene bestille direkte via web, så jeg droppet oppføring der.
-Jeg har spurt Haugen bok og Tronsmo direkte på epost om de er
-interessert i å ta inn boken i sin bestillingskatalog, men ikke fått
-svar, så jeg antar de ikke er interessert. Derimot har jeg fått en
-hyggelig henvendelse fra Biblioteksentralen som fortalte at de har
-lagt den inn i sin database slik at deres bibliotekskunder enkelt kan
-bestille den via dem.</p>
-
-<p>Boken er i følge

+ <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
+box, you need the Linux kernel version 4.1 or later. I tested on a
+Debian Stretch machine (kernel version 4.9), and there it worked just
+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>
-The GPL is not magic pixie dust. It does not work by itself.<br/>
-
-The first step is to choose a
-<a href="https://copyleft.org/">copyleft</a> license for your
-code.<br/>
-
-The next step is, when someone fails to follow that copyleft license,
-<b>it must be enforced</b><br/>
-
-and its a simple fact of our modern society that such type of
-work<br/>
+<blockquote><pre>

-is incredibly expensive to do and incredibly difficult to do.

+<p>The entropy level increases by 3-4 every second. In such case any

+will halt and wait for more entrpy. And here is the situation with

-imply, public domain and permissively licensed software can lead to
-the production of more proprietary software as people discover useful
-software, extend it and or incorporate it into their hardware or
-software products. Copyleft licenses such as the GNU GPL were created
-to close off this avenue to the production of proprietary software but
-such licenses are not enough. With the ongoing adoption of Free
-Software by individuals and groups, inevitably the community's
-expectations of license compliance are violated, usually out of
-ignorance of the way Free Software works, but not always. As Karen

-Freedom Conservancy</a> (a tax-exempt charity) is the major defender
-of the Linux project, Debian and other groups against GPL violations.
-In March the SFC supported a

-by Christoph Hellwig</a> against VMware for refusing to
-<a href="https://sfconservancy.org/linux-compliance/vmware-lawsuit-faq.html">comply
-with the GPL</a> in relation to their use of parts of the Linux
-kernel. Since then two of their sponsors pulled corporate funding and
-conferences
-<a href="https://sfconservancy.org/blog/2015/nov/24/faif-carols-fundraiser/">blocked
-or cancelled their talks</a>. As a result they have decided to rely
-less on corporate funding and more on the broad community of
-individuals who support Free Software and copyleft. So the SFC has
-<a href="https://sfconservancy.org/news/2015/nov/23/2015fundraiser/">launched</a>
-a <a href="https://sfconservancy.org/supporter/">campaign</a> to create

+<p>Is there any tool to detect if a OOXML document depend on such
+undefined behaviour? It would be useful for the National Archive (and
+anyone else interested in verifying that a document is well defined)
+to have such tool available when considering to approve the use of
+OOXML. I'm aware of the
+<a href="https://github.com/arlm/officeotron/">officeotron OOXML
+validator</a>, but do not know how complete it is nor if it will
+report use of undefined behaviour. Are there other similar tools
+available? Please send me an email if you know of any such tool.</p>
