Lawrence Lessig interviewed Edward Snowden a year ago
-
19th October 2015
-

Last year, US president candidate -in the Democratic Party Lawrence interviewed Edward Snowden. The -one hour interview was -published by -Harvard Law School 2014-10-23 on Youtube, and the meeting took -place 2014-10-20.

- -

The questions are very good, and there is lots of useful -information to be learned and very interesting issues to think about -being raised. Please check it out.

- - - -

I find it especially interesting to hear again that Snowden did try -to bring up his reservations through the official channels without any -luck. It is in sharp contrast to the answers made by the Norwegian -prime minister Erna Solberg said 2013-11-06 to the Norwegian -Parliament, -claiming -Snowden is no Whistle-Blower because he should have taken up his -concerns internally and using official channels. It make me sad -that this is the political leadership we have here in Norway.

Simpler recipe on how to make a simple $7 IMSI Catcher using Debian
+
9th August 2017
+

On friday, I came across an interesting article in the Norwegian +web based ICT news magazine digi.no on +how +to collect the IMSI numbers of nearby cell phones using the cheap +DVB-T software defined radios. The article refered to instructions +and a recipe by +Keld Norman on Youtube on how to make a simple $7 IMSI Catcher, and I decided to test them out.

+ +

The instructions said to use Ubuntu, install pip using apt (to +bypass apt), use pip to install pybombs (to bypass both apt and pip), +and the ask pybombs to fetch and build everything you need from +scratch. I wanted to see if I could do the same on the most recent +Debian packages, but this did not work because pybombs tried to build +stuff that no longer build with the most recent openssl library or +some other version skew problem. While trying to get this recipe +working, I learned that the apt->pip->pybombs route was a long detour, +and the only piece of software dependency missing in Debian was the +gr-gsm package. I also found out that the lead upstream developer of +gr-gsm (the name stand for GNU Radio GSM) project already had a set of +Debian packages provided in an Ubuntu PPA repository. All I needed to +do was to dget the Debian source package and built it.

+ +

The IMSI collector is a python script listening for packages on the +loopback network device and printing to the terminal some specific GSM +packages with IMSI numbers in them. The code is fairly short and easy +to understand. The reason this work is because gr-gsm include a tool +to read GSM data from a software defined radio like a DVB-T USB stick +and other software defined radios, decode them and inject them into a +network device on your Linux machine (using the loopback device by +default). This proved to work just fine, and I've been testing the +collector for a few days now.

+ +

The updated and simpler recipe is thus to

+ +
    + +
  1. start with a Debian machine running Stretch or newer,
    2. + +
  2. build and install the gr-gsm package available from +http://ppa.launchpad.net/ptrkrysik/gr-gsm/ubuntu/pool/main/g/gr-gsm/,
    3. + +
  3. clone the git repostory from https://github.com/Oros42/IMSI-catcher,
    4. + +
  4. run grgsm_livemon and adjust the frequency until the terminal +where it was started is filled with a stream of text (meaning you +found a GSM station).
    5. + +
  5. go into the IMSI-catcher directory and run 'sudo python simple_IMSI-catcher.py' to extract the IMSI numbers.
    6. + +
+ +

To make it even easier in the future to get this sniffer up and +running, I decided to package +the gr-gsm project +for Debian (WNPP +#871055), and the package was uploaded into the NEW queue today. +Luckily the gnuradio maintainer has promised to help me, as I do not +know much about gnuradio stuff yet.

+ +

I doubt this "IMSI cacher" is anywhere near as powerfull as +commercial tools like +The +Spy Phone Portable IMSI / IMEI Catcher or the +Harris +Stingray, but I hope the existance of cheap alternatives can make +more people realise how their whereabouts when carrying a cell phone +is easily tracked. Seeing the data flow on the screen, realizing that +I live close to a police station and knowing that the police is also +wearing cell phones, I wonder how hard it would be for criminals to +track the position of the police officers to discover when there are +police near by, or for foreign military forces to track the location +of the Norwegian military forces, or for anyone to track the location +of government officials...

+ +

It is worth noting that the data reported by the IMSI-catcher +script mentioned above is only a fraction of the data broadcasted on +the GSM network. It will only collect one frequency at the time, +while a typical phone will be using several frequencies, and not all +phones will be using the frequencies tracked by the grgsm_livemod +program. Also, there is a lot of radio chatter being ignored by the +simple_IMSI-catcher script, which would be collected by extending the +parser code. I wonder if gr-gsm can be set up to listen to more than +one frequency?

The Story of Aaron Swartz - Let us all weep!

Alle Stortingets mobiltelefoner kontrolleres fra USA...
-
7th October 2015
-

Jeg lot meg fascinere av -en -artikkel i Aftenposten der det fortelles at «over 600 telefoner som -benyttes av stortingsrepresentanter, rådgivere og ansatte på -Stortinget, kan «fjernstyres» ved hjelp av -programvaren -Airwatch, et såkalte MDM-program (Mobile Device Managment)». Det -hele bagatelliseres av Stortingets IT-stab, men det er i hovedsak på -grunn av at journalisten ikke stiller de relevante spørsmålene. For -meg er det relevante spørsmålet hvem som har lovlig tilgang (i henhold -til lokal lovgiving, dvs. i hvert fall i Norge, Sverige, UK og USA) -til informasjon om og på telefonene, og hvor enkelt det er å skaffe -seg tilgang til hvor mobilene befinner seg og informasjon som befinner -seg på telefonene ved hjelp av utro tjenere, trusler, innbrudd og -andre ulovlige metoder.

- -

Bruken av AirWatch betyr i realiteten at USAs etteretning og -politimyndigheter har full tilgang til stortingets mobiltelefoner, -inkludert posisjon og innhold, takket være -FISAAA-loven -og -"National -Security Letters" og det enkle faktum at selskapet -AirWatch er kontrollert av et -selskap i USA. I tillegg er det kjent at flere lands -etterretningstjenester kan lytte på trafikken når den passerer -landegrensene.

- -

Jeg har bedt om mer informasjon -fra -Stortinget om bruken av AirWatch via Mimes brønn så får vi se hva -de har å fortelle om saken. Fant ingenting om 'airwatch' i -postjournalen til Stortinget, så jeg trenger hjelp før jeg kan be om -innsyn i konkrete dokumenter.

- -

Oppdatering 2015-10-07: Jeg er blitt spurt hvorfor jeg antar at -AirWatch-agenten rapporterer til USA og ikke direkte til Stortingets -egen infrastruktur. Det stemmer at det er teknisk mulig å sette -opp mobiltelefonene til å rapportere til datamaskiner som eies av -Stortinget. Jeg antar det rapporteres til AirWatch sine sentrale -tjenester basert på det jeg leste fra beskrivelsen av -Mobile -Device Management på AirWatch sine egne nettsider, koblet med at -det brukes en standard app som kan hentes fra "app-butikkene" for å få -tilgang. Enten må app-en settes opp individuelt hos Stortinget, eller -så får den beskjed fra AirWatch i USA om hvor den skal koble seg opp. -I det første tilfellet vil den ikke rapportere direkte til USA, men -til programvare utviklet av AirWatch som kjører på en maskin under -Stortingets kontroll. Det er litt bedre, men fortsatt vil det være -umulig for Stortinget å være sikker på hva programvaren som tar imot -forbindelser gjør. Jeg ser fra beskrivelsen av -Enterprice -Integration hos AirWatch at det er mulig å ha lokal installasjon, -og håper innsynsforespørsler mot Stortinget kan fortelle mer om -hvordan ting konkret fungerer der.

«Rapporten ser ikke på informasjonssikkerhet knyttet til personlig integritet»
+
27th June 2017
+

Jeg kom over teksten +«Killing +car privacy by federal mandate» av Leonid Reyzin på Freedom to +Tinker i dag, og det gleder meg å se en god gjennomgang om hvorfor det +er et urimelig inngrep i privatsfæren å la alle biler kringkaste sin +posisjon og bevegelse via radio. Det omtalte forslaget basert på +Dedicated Short Range Communication (DSRC) kalles Basic Safety Message +(BSM) i USA og Cooperative Awareness Message (CAM) i Europa, og det +norske Vegvesenet er en av de som ser ut til å kunne tenke seg å +pålegge alle biler å fjerne nok en bit av innbyggernes privatsfære. +Anbefaler alle å lese det som står der. + +

Mens jeg tittet litt på DSRC på biler i Norge kom jeg over et sitat +jeg synes er illustrativt for hvordan det offentlige Norge håndterer +problemstillinger rundt innbyggernes privatsfære i SINTEF-rapporten +«Informasjonssikkerhet +i AutoPASS-brikker» av Trond Foss:

+ +

+«Rapporten ser ikke på informasjonssikkerhet knyttet til personlig + integritet.» +

+ +

Så enkelt kan det tydeligvis gjøres når en vurderer +informasjonssikkerheten. Det holder vel at folkene på toppen kan si +at «Personvernet er ivaretatt», som jo er den populære intetsigende +frasen som gjør at mange tror enkeltindividers integritet tas vare på. +Sitatet fikk meg til å undres på hvor ofte samme tilnærming, å bare se +bort fra behovet for personlig itegritet, blir valgt når en velger å +legge til rette for nok et inngrep i privatsfæren til personer i +Norge. Det er jo sjelden det får reaksjoner. Historien om +reaksjonene på Helse Sør-Østs tjenesteutsetting er jo sørgelig nok et +unntak og toppen av isfjellet, desverre. Tror jeg fortsatt takker nei +til både AutoPASS og holder meg så langt unna det norske helsevesenet +som jeg kan, inntil de har demonstrert og dokumentert at de verdsetter +individets privatsfære og personlige integritet høyere enn kortsiktig +gevist og samfunnsnytte.

The life and death of a laptop battery
-
24th September 2015
-

When I get a new laptop, the battery life time at the start is OK. -But this do not last. The last few laptops gave me a feeling that -within a year, the life time is just a fraction of what it used to be, -and it slowly become painful to use the laptop without power connected -all the time. Because of this, when I got a new Thinkpad X230 laptop -about two years ago, I decided to monitor its battery state to have -more hard facts when the battery started to fail.

- - - -

First I tried to find a sensible Debian package to record the -battery status, assuming that this must be a problem already handled -by someone else. I found -battery-stats, -which collects statistics from the battery, but it was completely -broken. I sent a few suggestions to the maintainer, but decided to -write my own collector as a shell script while I waited for feedback -from him. Via -a -blog post about the battery development on a MacBook Air I also -discovered -batlog, not -available in Debian.

- -

I started my collector 2013-07-15, and it has been collecting -battery stats ever since. Now my -/var/log/hjemmenett-battery-status.log file contain around 115,000 -measurements, from the time the battery was working great until now, -when it is unable to charge above 7% of original capacity. My -collector shell script is quite simple and look like this:

- -
-#!/bin/sh
-# Inspired by

-    (
-	printf "timestamp,"
-	for f in $files; do
-	    printf "%s," $f
-	done
-	echo
-    ) > "$logfile"
-fi
-
-log_battery() {
-    # Print complete message in one echo call, to avoid race condition
-    # when several log processes run in parallel.
-    msg=$(printf "%s," $(date +%s); \
-	for f in $files; do \
-	    printf "%s," $(cat $f); \
-	done)
-    echo "$msg"
-}
-
-cd /sys/class/power_supply
-
-for bat in BAT*; do
-    (cd $bat && log_battery >> "$logfile")
-done
-
- -

The script is called when the power management system detect a -change in the power status (power plug in or out), and when going into -and out of hibernation and suspend. In addition, it collect a value -every 10 minutes. This make it possible for me know when the battery -is discharging, charging and how the maximum charge change over time. -The code for the Debian package -is now -available on github.

- -

The collected log file look like this:

- -
-timestamp,manufacturer,model_name,technology,serial_number,energy_full,energy_full_design,energy_now,cycle_count,status,

- -

I wrote a small script to create a graph of the charge development -over time. This graph depicted above show the slow death of my laptop -battery.

- -

But why is this happening? Why are my laptop batteries always -dying in a year or two, while the batteries of space probes and -satellites keep working year after year. If we are to believe -Battery -University, the cause is me charging the battery whenever I have a -chance, and the fix is to not charge the Lithium-ion batteries to 100% -all the time, but to stay below 90% of full charge most of the time. -I've been told that the Tesla electric cars -limit -the charge of their batteries to 80%, with the option to charge to -100% when preparing for a longer trip (not that I would want a car -like Tesla where rights to privacy is abandoned, but that is another -story), which I guess is the option we should have for laptops on -Linux too.

- -

Is there a good and generic way with Linux to tell the battery to -stop charging at 80%, unless requested to charge to 100% once in -preparation for a longer trip? I found -one -recipe on askubuntu for Ubuntu to limit charging on Thinkpad to -80%, but could not get it to work (kernel module refused to -load).

- -

I wonder why the battery capacity was reported to be more than 100% -at the start. I also wonder why the "full capacity" increases some -times, and if it is possible to repeat the process to get the battery -back to design capacity. And I wonder if the discharge and charge -speed change over time, or if this stay the same. I did not yet try -to write a tool to calculate the derivative values of the battery -level, but suspect some interesting insights might be learned from -those.

- -

Update 2015-09-24: I got a tip to install the packages -acpi-call-dkms and tlp (unfortunately missing in Debian stable) -packages instead of the tp-smapi-dkms package I had tried to use -initially, and use 'tlp setcharge 40 80' to change when charging start -and stop. I've done so now, but expect my existing battery is toast -and need to be replaced. The proposal is unfortunately Thinkpad -specific.

Book cover for the Free Culture book finally done

Not only did he create a -SVG document with -the original and his vector version side by side, he even provided -an instruction -video explaining how he did it. But the instruction video is -not easy to follow for an untrained inkscape user. The video is a -recording on how he did it, and he is obviously very experienced as -the menu selections are very quick and he mentioned on IRC that he did -use some keyboard shortcuts that can't be seen on the video, but it -give a good idea about the inkscape operations to use to create the -stripes with the embossed copyright sign in the center.

Idea for storing trusted timestamps in a Noark 5 archive
+
7th June 2017
+

This is a copy of +an +email I posted to the nikita-noark mailing list. 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 +Noark +5 standard for government archives.

+ +

I've been wondering a bit lately how trusted timestamps could be +stored in Noark 5. +Trusted +timestamps 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.

+ +

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?

+ +

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:

+ +
    + +
  • format -> "RFC3161" +
  • mimeType -> "application/timestamp-reply" +
  • formatDetaljer -> "<source URL for timestamp service>" +
  • filenavn -> "<sjekksum>.tsr" + +
+ +

This assume a service following +IETF RFC 3161 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.

+ +

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.

+ +

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 ".tsr" value mentioned +above).

+ +

+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
+

+ +

To verify the timestamp, you first need to download the public key +of the trusted timestamp service, for example using this command:

+ +

+wget -O ca-cert.txt \
+  https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt
+

+ +

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. :)

+ +

The verification itself is a simple openssl command:

+ +

+openssl ts -verify -data $inputfile -in $sha256.tsr \
+  -CAfile ca-cert.txt -text
+

+ +

In my hand, a pocket book edition of the Norwegian Free Culture book!
-
19th August 2015
-

Today, finally, my first printed draft edition of the Norwegian -translation of Free Culture I have been working on for the last few -years arrived in the mail. I had to fake a cover to get the interior -printed, and the exterior of the book look awful, but that is -irrelevant at this point. I asked for a printed pocket book version -to get an idea about the font sizes and paper format as well as how -good the figures and images look in print, but also to test what the -pocket book version would look like. After receiving the 500 page -pocket book, it became obvious to me that that pocket book size is too -small for this book. I believe the book is too thick, and several -tables and figures do not look good in the size they get with that -small page sizes. I believe I will go with the 5.5x8.5 inch size -instead. A surprise discovery from the paper version was how bad the -URLs look in print. They are very hard to read in the colophon page. -The URLs are red in the PDF, but light gray on paper. I need to -change the color of links somehow to look better. But there is a -printed book in my hand, and it feels great. :)

- -

Now I only need to fix the cover, wrap up the postscript with the -store behind the book, and collect the last corrections from the proof -readers before the book is ready for proper printing. Cover artists -willing to work for free and create a Creative Commons licensed vector -file looking similar to the original is most welcome, as my skills as -a graphics designer are mostly missing.

NÃ¥r nynorskoversettelsen svikter til eksamen...
+
3rd June 2017
+

Aftenposten +melder i dag 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 +Apertium ville gjort en bedre +jobb enn Utdanningsdirektoratet. Det kan se slik ut.

+ +

Her er bokmålsoppgaven fra eksamenen:

+ +
+

Drøft utfordringene knyttet til nasjonalstatenes og andre aktørers +rolle og muligheter til å håndtere internasjonale utfordringer, som +for eksempel flykningekrisen.

+ +

Vedlegge er eksempler på tekster som kan gi relevante perspektiver +på temaet:

+
    +
  1. Flykningeregnskapet 2016, UNHCR og IDMC +
  2. «Grenseløst Europa for fall» A-Magasinet, 26. november 2015 +
+ +
+ +

Dette oversetter Apertium slik:

+ +
+

Drøft utfordringane knytte til nasjonalstatane sine og rolla til +andre aktørar og høve til å handtera internasjonale utfordringar, som +til dømes *flykningekrisen.

+ +

Vedleggja er døme på tekster som kan gje relevante perspektiv på +temaet:

+ +
    +
  1. *Flykningeregnskapet 2016, *UNHCR og *IDMC
    2. +
  2. «*Grenseløst Europa for fall» A-Magasinet, 26. november 2015
    3. +
+ +
+ +

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.

First paper version of the Norwegian Free Culture book heading my way
-
9th August 2015
-

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 -docbook based version of the -Free Culture 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.

- -

Last night, I finally managed to create a PDF that no longer made -Lulu.com 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.

- -

Instead of using Lulu, I did consider printing the book using -CreateSpace, 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.

- -

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.

- -

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.

- -

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 -github -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.

- -

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.

Epost inn som arkivformat i Riksarkivarens forskrift?
+
27th April 2017
+

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 +Noark +5-løsninger i Norge.

+ +

Jeg fant høringsdokumentene hos +Norsk +Arkivråd etter å ha blitt tipset på epostlisten til +fri +programvareprosjektet Nikita Noark5-Core, 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 +egen +høringsuttalelse, og lurer på om andre er interessert i å støtte +forslaget om å tillate arkivering av epost som epost i arkivet.

+ +

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:

+ +

+ +

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).

+ +

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, + https://tools.ietf.org/html/rfc5322. 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.

+ +

+ +

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 +følge +fremdriften på web.

+ +

Oppdatering 2017-04-28: I dag ble høringuttalelsen jeg skrev + sendt + inn av foreningen NUUG.

Typesetting DocBook footnotes as endnotes with dblatex
-
16th July 2015
-

I'm still working on the Norwegian version of the -Free Culture book by Lawrence -Lessig, 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 -feedback from the Debian -maintainer and the dblatex developer, 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.

- -

First, decide where in the DocBook document to place the endnotes, -and add this text there:

- -
-<?latex \theendnotes ?>
-
- -

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:

- -
-<?xml version='1.0'?>
-<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'>
-  <xsl:param name="latex.begindocument">
-    <xsl:text>
-\usepackage{endnotes}
-\let\footnote=\endnote
-\def\enoteheading{\mbox{}\par\vskip-\baselineskip }
-\begin{document}
-    </xsl:text>
-  </xsl:param>
-</xsl:stylesheet>
-
- -

Finally, load this xsl file when running dblatex, for example like -this:

- -
-dblatex --xsl-user=dblatex-endnotes.xsl freeculture.nb.xml
-
- -

The end result can be seen on github, where -my -book project is located.

Offentlig elektronisk postjournal blokkerer tilgang for utvalgte webklienter
+
20th April 2017
+

Jeg oppdaget i dag at nettstedet som +publiserer offentlige postjournaler fra statlige etater, OEP, har +begynt å blokkerer enkelte typer webklienter fra å få tilgang. Vet +ikke hvor mange det gjelder, men det gjelder i hvert fall libwww-perl +og curl. For å teste selv, kjør følgende:

+ +
+% curl -v -s https://www.oep.no/pub/report.xhtml?reportId=3 2>&1 |grep '< HTTP'
+< HTTP/1.1 404 Not Found
+% curl -v -s --header 'User-Agent:Opera/12.0' https://www.oep.no/pub/report.xhtml?reportId=3 2>&1 |grep '< HTTP'
+< HTTP/1.1 200 OK
+%
+
+ +

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.

+ +

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 +rapporten +«Slik hindrer departementer innsyn» som ble publiserte i januar +2017. Det virker usannsynlig, da det jo er trivielt å bytte +User-Agent til noe nytt.

+ +

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 +aktørene man kan be om innsyn i for å forstå hva som har skjedd. Men +postjournalen +til DIFI viser kun to dokumenter det siste året mellom DIFI og +Basefarm. +Mimes brønn neste, +tenker jeg.

Mimes brønn, norsk utgave av Alaveteli / WhatDoTheyKnow, endelig lansert
-
9th July 2015
-

I går fikk vi endelig lansert en norsk version av mySocietys -WhatDoTheyKnow. -Tjenesten heter Mimes brønn, og ble -annonsert -av NUUG 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.

- -

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.

- -

Hvis du lurer på hva i alle dager en slik tjenestes kan brukes til, -anbefaler jeg deg å se -TED-foredraget til -Heather Brook om hvordan hun brukte WhatDoTheyKnow til å lære -hvordan offentlige midler ble misbrukt. Det er en inspirerende -historie.

Free software archive system Nikita now able to store documents
+
19th March 2017
+

The Nikita +Noark 5 core project is implementing the Norwegian standard for +keeping an electronic archive of government documents. +The +Noark 5 standard 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 +announced +it supported the project. 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.

+ +

If you would like to help make sure there is a free software +alternatives for the archives, please join our IRC channel +(#nikita on +irc.freenode.net) and +the +project mailing list.

+ +

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 +archive-pdf to upload a PDF file to the archive using this +API. The tool is very simple at the moment, and find existing +fonds, 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:

+ +

+~/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
+
+ 0 - Title of the test case file created 2017-03-18T23:49:32.103446
+ 1 - Title of the test file created 2017-03-18T23:49:32.103446
+Select which mappe you want (or search term): 0
+Uploading mangelmelding/mangler.pdf
+  PDF title: Mangler i spesifikasjonsdokumentet for NOARK 5 Tjenestegrensesnitt
+  File 2017/1: Title of the test case file created 2017-03-18T23:49:32.103446
+~/src//noark5-tester$
+

+ +

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 archive-pdf +tool can be found in the git repository for the API tester.

+ +

In the project, I have been mostly working on +the API +tester so far, while getting to know the code base. The API +tester currently use +the HATEOAS links +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.

+ +

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 +started +writing down the questions we get from implementing it. We use a +format inspired by how The +Austin Group collect defect reports for the POSIX standard with +their +instructions for the MANTIS defect tracker system, in lack of an official way to structure defect reports for Noark 5 (our first submitted defect report was a request for a procedure for submitting defect reports :). + +

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.
