-menneskerettighetserklæring</a> artikkel 13 første punkt lyder som
-følger:</p>
-
-<p><blockquote>
-Enhver har rett til å bevege seg fritt og til fritt å velge
-oppholdssted innenfor en stats grenser.
-</blockquote></p>
-
-<p>Det er altså en menneskerett å kunne bevege seg fritt i landet.
-For å bevege seg fritt i landet, så må en kunne bevege seg uten å bli
-sporet. Det vil i dagens samfunn innebære å bevege seg uten å legge
-igjen digitale spor og uten å være radiomerket. Hvis en vet at ens
-bevegelser, hvor en befinner seg når, og hvem som befinner seg i
-nærheten, blir samlet inn og gjort tilgjengelig for fremmede, det være
-seg myndighetene eller private organisasjoner, så kan en ikke lenger
-bevege seg fritt. Dette gjør at det er en forutsetning for å ha glede
-av retten til å bevege seg fritt i landet at en motstår fristelsen til
-å legge igjen digitale spor når en betaler for seg. Rettigheter som
-ikke blir brukt, blit fjernet. Den eneste måten i dag å unngå å legge
-igjen digitale spor når en betaler for seg, er å betale med kontanter,
-samt takke nei til å legge igjen navn og adresse (slik f.eks. Elkjøp
-ber om — jeg sier de kan legge inn 'anonym anonym' når
-datasystemet deres trenger et navn). Personlig anbefaler jeg å
-konsekvent bruke kontant betaling når man beveger seg rundt, for å
-bidra til forsvaret av menneskerettighetene i Norge. Kanskje noe også
-for deg? Merk at det ikke er tilstrekkelig for å unngå sporing å
-betale med kontanter, men det er et lite steg i riktig retning.</p>
-
-<p>Det er flere andre argumenter i tillegg til
-menneskerettighetsargumentet for å bruke kontanter. I går hadde
-Dagbladet en utmerket kommentar av sin journalist John Olav Egeland om
-hvilket
-<a href="https://www.dagbladet.no/kultur/kontantlost-diktatur/70543434">kontantløst
-diktatur</a> som venter oss hvis mange nok slutter å insistere på å
-betale med kontanter. Jeg anbefaler deg å lese den.</p>

+ <div class="body"><p>Jeg er blitt spurt hva jeg synes om lansering av smittestopp-appen,
+overvåkningsløsningen lansert av Folkehelseinstituttet,
+Simula-senteret og Regjeringen i dag, fulgt av klare trusler fra
+regjeringen om konsekvenser hvis befolkningen ikke tar den i bruk.
+Rekker ikke skrive noe fyldig om temaet, men det er klart for meg at
+den utraderer retten til privatliv samt utgjør en personlig
+sikkerhetsrisiko for alle som tar den i bruk. Bare det er nok til at
+det fremstår som en svert dårlig ide å bli med på denne "dugnaden".
+Det finnes andre og bedre tilnærminger enn den valgt av FHI. Har de
+valgt den for å sikre seg nok et datasett i den fremtidige
+ehelse-portalen? Potensialet for misbruk av informasjon samlet inn av
+appen er for stort, effekten på neste krise for klar og gevinsten for
+liten.</p>
+
+<p>For å si det med forhenværende leder i Datatilsynet, Georg Apenes,
+som skrev i en kronikk den gang Datatilsynet vernet
+privatsfæren at
+«<a href="https://www.dagbladet.no/kultur/rent-mel-i-bilen/66333882">SENTRALT
+I en liberal forestillingsverden finner vi aksept av borgerens rett
+til å kunne velge å være i fred; å være u-iakttatt, uregistrert og
+anonym</a>». Det er ikke uten grunn han startet kronikken med
+«Personvern et fremmedord i enkelte av de statsorganene som samler
+inn, oppbevarer og bruker personopplysninger». Der har nok
+statsorganene bare blitt dårligere på 13 år.</p>
+
+<p>Det er jo også verdt å merke seg at personvernrådet i EU (EDPB)
+mener smittestopp-appen
+<a href="https://nrkbeta.no/2020/04/16/personvernrad-i-eu-mener-norsk-app-bryter-med-viktig-personvernprinsipp/">opererer
+i strid med prinsippet om dataminimering</a>. Også de ser at det

- <div class="body"><p>Yesterday, I had the pleasure of watching on Frikanalen the OWASP
-talk by Scott Helme titled
-"<a href="https://frikanalen.no/video/626080/">What We’ve Learned From
-Billions of Security Reports</a>". I had not heard of the
-<a href="https://en.wikipedia.org/wiki/Content_Security_Policy">Content
-Security Policy standard</a> nor its ability to "call home" when a
-browser detect a policy breach (I do not follow web page design
-development much these days), and found the talk very illuminating.</p>
-
-<p>The mechanism allow a web site owner to use HTTP headers to tell
-visitors web browser which sources (internal and external) are allowed to
-be used on the web site. Thus it become possible to enforce a "only
-local content" policy despite web designers urge to fetch programs
-from random sites on the Internet, like the one
-<a href="https://securityaffairs.co/wordpress/68966/hacking/browsealoud-plugin-hack.html">enabling
-the attack</a> reported by Scott Helme earlier this year.</p>
-
-<p>Using CSP seem like an obvious thing for a site admin to implement
-to take some control over the information leak that occur when
-external sources are used to render web pages, it is a mystery more
-sites are not using CSP? It is being
-<a href="https://www.w3.org/TR/CSP/">standardized under W3C</a> these
-days, and is supposed by most web browsers</p>
-
-<p>I managed to find <a href="https://github.com/mozilla/django-csp">a
-Django middleware for implementing CSP</a> and was happy to discover
-it was already in Debian. I plan to use it to add CSP support to the

- <div class="body"><p>If you read my blog regularly, you probably know I am involved in
-running and developing the <a href="https://frikanalen.no/">Norwegian
-TV channel Frikanalen</a>. It is an open channel, allowing everyone
-in Norway to publish videos on a TV channel with national coverage.
-You can think of it as Youtube for national television.
-In addition to distribution on RiksTV and Uninett, Frikanalen is also
-available as a Kodi addon. The last few days I have updated the code
-to add more features. A
-<a href="https://kodi.tv/addon/plugins-video-add-ons/frikanalen-nett-tv">new
-and improved version 0.0.3 Frikanalen addon</a> was just made
-available via the Kodi repositories. This new version include a
-option to browse videos by category, as well as free text search
-in the video archive. It will now also show the video duration in the
-video lists, which were missing earlier. A new and experimental
-link to the HD video stream currently being worked on is provided, for
-those that want to see what the <a href="https://casparcg.com/">CasparCG</a>
-output look like. The alternative is the SD video stream, generated
-using MLT. CasparCG is controlled by our
-<a href="https://github.com/Frikanalen/mltplayout/">mltplayout
-server</a> which instead of talking to mlt is giving PLAY instructions
-to the CasparCG server when it is time to start a new program.</p>
-
-<p>By now, you are probably wondering what kind of content is being
-played on the channel. These days, it is filled with technical
-presentations like those from <a href="https://www.nuug.no/">NUUG</a>,
-<a href="https://www.debconf.org/">Debconf</a>, Makercon, and TED,
-but there are also some periods with

-
-<p>My current home stereo is a patchwork of various pieces I got on
-flee markeds over the years. It is amazing what kind of equipment
-show up there. I've been wondering for a while if it was possible to
-measure how well this equipment is working together, and decided to
-see how far I could get using free software. After trawling the web I
-came across an article from DIY Audio and Video on
-<a href="https://www.diyaudioandvideo.com/Tutorial/SpeakerResponseTesting/">Speaker
-Testing and Analysis</a> describing how to test speakers, and it listing
-several software options, among them
-<a href="https://sourceforge.net/projects/audmes/">AUDio MEasurement
-System (AUDMES)</a>. It is the only free software system I could find
-focusing on measuring speakers and audio frequency response. In the
-process I also found an interesting article from NOVO on
-<a href="http://novo.press/understanding-speaker-specifications-and-frequency-response/">Understanding
-Speaker Specifications and Frequency Response</a> and an article from
-ecoustics on
-<a href="https://www.ecoustics.com/articles/understanding-speaker-frequency-response/">Understanding
-Speaker Frequency Response</a>, with a lot of information on what to
-look for and how to interpret the graphs. Armed with this knowledge,
-I set out to measure the state of my speakers.</p>
-
-<p>The first hurdle was that AUDMES hadn't seen a commit for 10 years
-and did not build with current compilers and libraries. I got in
-touch with its author, who no longer was spending time on the program
-but gave me write access to the subversion repository on Sourceforge.
-The end result is that now the code build on Linux and is capable of
-saving and loading the collected frequency response data in CSV
-format. The application is quite nice and flexible, and I was able to
-select the input and output audio interfaces independently. This made
-it possible to use a USB mixer as the input source, while sending
-output via my laptop headphone connection. I lacked the hardware and
-cabling to figure out a different way to get independent cabling to
-speakers and microphone.</p>
-
-<p>Using this setup I could see how a large range of high frequencies
-apparently were not making it out of my speakers. The picture show
-the frequency response measurement of one of the speakers. Note the
-frequency lines seem to be slightly misaligned, compared to the CSV
-output from the program. I can not hear several of these are high
-frequencies, according to measurement from
-<a href="http://freehearingtestsoftware.com">Free Hearing Test
-Software</a>, an freeware system to measure your hearing (still
-looking for a free software alternative), so I do not know if they are
-coming out out the speakers. I thus do not quite know how to figure
-out if the missing frequencies is a problem with the microphone, the
-amplifier or the speakers, but I managed to rule out the audio card in my
-PC by measuring my Bose noise canceling headset using its own
-microphone. This setup was able to see the high frequency tones, so
-the problem with my stereo had to be in the amplifier or speakers.</p>
-
-<p>Anyway, to try to role out one factor I ended up picking up a new
-set of speakers at a flee marked, and these work a lot better than the
-old speakers, so I guess the microphone and amplifier is OK. If you
-need to measure your own speakers, check out AUDMES. If more people
-get involved, perhaps the project could become good enough to
-<a href="https://bugs.debian.org/910876">include in Debian</a>? And if
-you know of some other free software to measure speakers and amplifier
-performance, please let me know. I am aware of the freeware option
-<a href="https://www.roomeqwizard.com/">REW</a>, but I want something
-that can be developed also when the vendor looses interest.</p>

+fra Arkivverket at det blir satt ned en redaksjon for å videreutvikle
+spesifikasjonen. Redaksjonen består av Mona Danielsen og Anne Sofie
+Knutsen ved arkivverket, Thomas Sødring ved OsloMet, og meg selv fra
+NUUG. De to sistenevnte tar seg av de åpenbare forbedringene, mens
+hele redaksjonen diskuterer tvilstilfeller. Jeg håper dette vil bidra
+til at vi lykkes i å gjøre denne protokollspesifikasjonen så entydig
+og klar at den vil bidra til et velfungerende marked for
+arkivsystemer, og sikre at programmer som trenger å snakke med
+arkivsystemet kan snakke med enhver implementasjon av
+API-spesifikasjonen. Nikita er den første implementasjonen, men det
+bør blir flere.</p>
+
+<p>Det gjenstår riktig nok endel før vi er i mål, selv om svært mye
+allerede er på plass. Med innspill og forslag til forbedringer fra
+alle som vil ha et leverandøruavhengig og fullstendig
+datamaskinlesbart grensesnitt til arkivet, så tror jeg vi vil
+lykkes.</p>

- <div class="date">21st October 2018</div>
- <div class="body"><p>Bittorrent is as far as I know, currently the most efficient way to
-distribute content on the Internet. It is used all by all sorts of
-content providers, from national TV stations like
-<a href="https://www.nrk.no/">NRK</a>, Linux distributors like
-<a href="https://www.debian.org/">Debian</a> and
-<a href="https://www.ubuntu.com/">Ubuntu</a>, and of course the
-<a href="https://archive.org/">Internet archive</A>.
-
-<p>Almost a month ago
-<a href="https://tracker.debian.org/pkg/vlc-plugin-bittorrent">a new
-package adding Bittorrent support to VLC</a> became available in
-Debian testing and unstable. To test it, simply install it like
-this:</p>
-
-<p><pre>
-apt install vlc-plugin-bittorrent
-</pre></p>
-
-<p>Since the plugin was made available for the first time in Debian,
-several improvements have been made to it. In version 2.2-4, now
-available in both testing and unstable, a desktop file is provided to
-teach browsers to start VLC when the user click on torrent files or
-magnet links. The last part is thanks to me finally understanding
-what the strange x-scheme-handler style MIME types in desktop files
-are used for. By adding x-scheme-handler/magnet to the MimeType entry
-in the desktop file, at least the browsers Firefox and Chromium will
-suggest to start VLC when selecting a magnet URI on a web page. The
-end result is that now, with the plugin installed in Buster and Sid,
-one can visit any
-<a href="https://archive.org/details/CopyingIsNotTheft1080p">Internet
-Archive page with movies</a> using a web browser and click on the
-torrent link to start streaming the movie.</p>
-
-<p>Note, there is still some misfeatures in the plugin. One is the
-fact that it will hang and
-<a href="https://github.com/johang/vlc-bittorrent/issues/13">block VLC
-from exiting until the torrent streaming starts</a>. Another is the
-fact that it
-<a href="https://github.com/johang/vlc-bittorrent/issues/9">will pick
-and play a random file in a multi file torrent</a>. This is not
-always the video file you want. Combined with the first it can be a
-bit hard to get the video streaming going. But when it work, it seem
-to do a good job.</p>
-
-<p>For the Debian packaging, I would love to find a good way to test
-if the plugin work with VLC using autopkgtest. I tried, but do not
-know enough of the inner workings of VLC to get it working. For now
-the autopkgtest script is only checking if the .so file was
-successfully loaded by VLC. If you have any suggestions, please
-submit a patch to the Debian bug tracking system.</p>

+tenker på når hverdagen tynger, ble så vidt jeg har klart å finne ut,
+skrevet av <a href="https://en.wikipedia.org/wiki/Loren_Eiseley">Loren
+Eiseley</a> <a href="https://en.wikipedia.org/wiki/The_Star_Thrower">i
+flere ulike varianter</a>. På norsk tror jeg den går under navnet
+«Gutten og sjøstjernen», og jeg fant en oversettelse av en utgave av den
+hos
+<a href="https://no.quora.com/Hva-er-din-favoritthistorie">Quora</a>.
+Fant også <a href="https://www.youtube.com/watch?v=-qClChUdlfI">en
+filmatisering</a>, men den versjonen jeg liker best fant jeg
+<a href="https://www.goodreads.com/author/quotes/56782.Loren_Eiseley">hos
+Goodreads</a>. Jeg oversatte den utgaven til norsk i går, og har lyst
+til å dele den med deg:
+
+<blockquote><p>Mens jeg tok en pause fra skrivingen og vandret på en
+øde strand ved daggry, så jeg en gutt i det fjerne bøye seg ned og
+kaste noe mens han vandret mot meg over den endeløse stranden. Da han
+kom nærmere, kunne jeg se at han kastet sjøstjerner, som var etterlatt
+i sanden av tidevannet, tilbake i havet. Da han var nær nok spurte jeg
+ham hvorfor han jobbet så hardt på denne merkelige oppgaven. Han sa at
+solen snart ville stå opp og tørke sjøstjernene slik at de ville
+dø.</p>
+
+<p>Jeg sa til ham at dette var helt meningsløst. Det var kilometer på
+kilometer med strand, og det lå sjøstjerner hele veien. En person
+alene kunne ikke gjøre noen forskjell. Han smilte da han plukket opp
+neste sjøstjerne. Mens han kastet den så langt ut i havet som han
+klarte sa han, «for denne gjør det en forskjell». Jeg droppet
+skrivingen og tilbrakte resten av morgenen med å kaste
+sjøstjerner.</p>

+håpløst?</p>
+
+<p>Teksten er gjengitt og oversatt basert på utgaven på Good Read,
+uten tillatelse fra noen andre enn meg selv. Jeg håper på tilgivelse,
+hvis det er et problem for noen, da det er gjort i beste mening. Hvis

- <div class="date"> 8th October 2018</div>
- <div class="body"><p>I have earlier covered the basics of trusted timestamping using the
-'openssl ts' client. See blog post for
-<a href="http://people.skolelinux.org/pere/blog/Public_Trusted_Timestamping_services_for_everyone.html">2014</a>,
-<a href="http://people.skolelinux.org/pere/blog/syslog_trusted_timestamp___chain_of_trusted_timestamps_for_your_syslog.html">2016</a>
-and
-<a href="http://people.skolelinux.org/pere/blog/Idea_for_storing_trusted_timestamps_in_a_Noark_5_archive.html">2017</a>
-for those stories. But some times I want to integrate the timestamping
-in other code, and recently I needed to integrate it into Python.
-After searching a bit, I found
-<a href="https://dev.entrouvert.org/projects/python-rfc3161">the
-rfc3161 library</a> which seemed like a good fit, but I soon
-discovered it only worked for python version 2, and I needed something
-that work with python version 3. Luckily I next came across
-<a href="https://github.com/trbs/rfc3161ng/">the rfc3161ng library</a>,
-a fork of the original rfc3161 library. Not only is it working with
-python 3, it have fixed a few of the bugs in the original library, and
-it has an active maintainer. I decided to wrap it up and make it
-<a href="https://tracker.debian.org/pkg/python-rfc3161ng">available in
-Debian</a>, and a few days ago it entered Debian unstable and testing.</p>
-
-<p>Using the library is fairly straight forward. The only slightly
-problematic step is to fetch the required certificates to verify the
-timestamp. For some services it is straight forward, while for others
-I have not yet figured out how to do it. Here is a small standalone
-code example based on of the integration tests in the library code:</p>
-
-<pre>
-#!/usr/bin/python3
-
-"""
-
-Python 3 script demonstrating how to use the rfc3161ng module to
-get trusted timestamps.
-
-The license of this code is the same as the license of the rfc3161ng
-library, ie MIT/BSD.

-
-import os
-import pyasn1.codec.der
-import rfc3161ng
-import subprocess
-import tempfile
-import urllib.request
-
-def store(f, data):
- f.write(data)
- f.flush()
- f.seek(0)
-
-def fetch(url, f=None):
- response = urllib.request.urlopen(url)
- data = response.read()
- if f:
- store(f, data)
- return data
-
-def main():
- with tempfile.NamedTemporaryFile() as cert_f,\
- tempfile.NamedTemporaryFile() as ca_f,\
- tempfile.NamedTemporaryFile() as msg_f,\
- tempfile.NamedTemporaryFile() as tsr_f:
-
- # First fetch certificates used by service
- certificate_data = fetch('https://freetsa.org/files/tsa.crt', cert_f)
- ca_data_data = fetch('https://freetsa.org/files/cacert.pem', ca_f)
-
- # Then timestamp the message
- timestamper = \
- rfc3161ng.RemoteTimestamper('http://freetsa.org/tsr',
- certificate=certificate_data)
- data = b"Python forever!\n"
- tsr = timestamper(data=data, return_tsr=True)
-
- # Finally, convert message and response to something 'openssl ts' can verify
- store(msg_f, data)
- store(tsr_f, pyasn1.codec.der.encoder.encode(tsr))
- args = ["openssl", "ts", "-verify",

- "-CAfile", ca_f.name,
- "-untrusted", cert_f.name]
- subprocess.check_call(args)
-
-if '__main__' == __name__:
- main()
-</pre>
-
-<p>The code fetches the required certificates, store them as temporary
-files, timestamp a simple message, store the message and timestamp to
-disk and ask 'openssl ts' to verify the timestamp. A timestamp is
-around 1.5 kiB in size, and should be fairly easy to store for future
-use.</p>

-Here is a sketch of the setup for future reference.</p>
-
-<p>I first created <tt>~/googledrive</tt>, entered the directory and
-ran '<tt>grive -a</tt>' to authenticate the machine/user. Next, I
-created a autostart hook in <tt>~/.config/autostart/grive.desktop</tt>
-to start the sync when the user log in:</p>
-
-<p><blockquote><pre>
-[Desktop Entry]
-Name=Google drive autosync
-Type=Application
-Exec=/home/user/bin/grive-sync
-</pre></blockquote></p>
-
-<p>Finally, I wrote the <tt>~/bin/grive-sync</tt> script to sync
-~/googledrive/ with the files in Google Drive.</p>

- <div class="date">29th September 2018</div>
- <div class="body"><p>It would come as no surprise to anyone that I am interested in
-bitcoins and virtual currencies. I've been keeping an eye on virtual
-currencies for many years, and it is part of the reason a few months
-ago, I started writing a python library for collecting currency
-exchange rates and trade on virtual currency exchanges. I decided to
-name the end result valutakrambod, which perhaps can be translated to
-small currency shop.</p>
-
-<p>The library uses the tornado python library to handle HTTP and
-websocket connections, and provide a asynchronous system for
-connecting to and tracking several services. The code is available
-from
-<a href="http://github.com/petterreinholdtsen/valutakrambod">github</a>.</p>
-
-</p>There are two example clients of the library. One is very simple and
-list every updated buy/sell price received from the various services.
-This code is started by running bin/btc-rates and call the client code
-in valutakrambod/client.py. The simple client look like this:</p>
-
-<p><blockquote><pre>
-import functools
-import tornado.ioloop
-import valutakrambod
-class SimpleClient(object):
- def __init__(self):
- self.services = []
- self.streams = []
- pass
- def newdata(self, service, pair, changed):
- print("%-15s %s-%s: %8.3f %8.3f" % (
- service.servicename(),
- pair[0],
- pair[1],
- service.rates[pair]['ask'],
- service.rates[pair]['bid'])
- )
- async def refresh(self, service):
- await service.fetchRates(service.wantedpairs)
- def run(self):
- self.ioloop = tornado.ioloop.IOLoop.current()
- self.services = valutakrambod.service.knownServices()
- for e in self.services:
- service = e()
- service.subscribe(self.newdata)
- stream = service.websocket()
- if stream:
- self.streams.append(stream)
- else:
- # Fetch information from non-streaming services immediately
- self.ioloop.call_later(len(self.services),
- functools.partial(self.refresh, service))
- # as well as regularly
- service.periodicUpdate(60)
- for stream in self.streams:
- stream.connect()
- try:
- self.ioloop.start()
- except KeyboardInterrupt:
- print("Interrupted by keyboard, closing all connections.")
- pass
- for stream in self.streams:
- stream.close()
-</pre></blockquote></p>
-
-<p>The library client loops over all known "public" services,
-initialises it, subscribes to any updates from the service, checks and
-activates websocket streaming if the service provide it, and if no
-streaming is supported, fetches information from the service and sets
-up a periodic update every 60 seconds. The output from this client
-can look like this:</p>
-
-<p><blockquote><pre>
-Bl3p BTC-EUR: 5687.110 5653.690
-Bl3p BTC-EUR: 5687.110 5653.690
-Bl3p BTC-EUR: 5687.110 5653.690
-Hitbtc BTC-USD: 6594.560 6593.690
-Hitbtc BTC-USD: 6594.560 6593.690
-Bl3p BTC-EUR: 5687.110 5653.690
-Hitbtc BTC-USD: 6594.570 6593.690
-Bitstamp EUR-USD: 1.159 1.154
-Hitbtc BTC-USD: 6594.570 6593.690
-Hitbtc BTC-USD: 6594.580 6593.690
-Hitbtc BTC-USD: 6594.580 6593.690
-Hitbtc BTC-USD: 6594.580 6593.690
-Bl3p BTC-EUR: 5687.110 5653.690
-Paymium BTC-EUR: 5680.000 5620.240
-</pre></blockquote></p>
-
-<p>The exchange order book is tracked in addition to the best buy/sell
-price, for those that need to know the details.</p>
-
-<p>The other example client is focusing on providing a curses view
-with updated buy/sell prices as soon as they are received from the
-services. This code is located in bin/btc-rates-curses and activated
-by using the '-c' argument. Without the argument the "curses" output
-is printed without using curses, which is useful for debugging. The
-curses view look like this:</p>

-<p>The code for this client is too complex for a simple blog post, so
-you will have to check out the git repository to figure out how it
-work. What I can tell is how the three last numbers on each line
-should be interpreted. The first is how many seconds ago information
-was received from the service. The second is how long ago, according
-to the service, the provided information was updated. The last is an
-estimate on how often the buy/sell values change.</p>
-
-<p>If you find this library useful, or would like to improve it, I
-would love to hear from you. Note that for some of the services I've
-implemented a trading API. It might be the topic of a future blog
-post.</p>

+ <div class="date">25th November 2019</div>
+ <div class="body"><p>Four years ago, I did a back of the envelope calculation on
+<a href="http://people.skolelinux.org/pere/blog/What_would_it_cost_to_store_all_phone_calls_in_Norway_.html">how
+much it would cost to store audio recordings of all the phone calls in
+Norway</a>, and came up with NOK 2.1 million / EUR 250 000 for the
+year 2013. It is time to repeat the calculation using updated
+numbers. The calculation is based on how much data storage is needed
+for each minute of audio, how many minutes all the calls in Norway
+sums up to, multiplied by the cost of data storage.</p>
+
+<p>The number of phone call minutes for 2018 was fetched from
+<a href="https://ekomstatistikken.nkom.no/">the NKOM statistics
+site</a>, and for 2018, land line calls are listed as 434 238 000
+minutes, while mobile phone calls are listed with 7 542 006 000
+minutes. The total number of minutes is thus 7 976 244 000. For
+simplicity, I decided to ignore any advantages in audio compression the
+last four years, and continue to assume 60 Kbytes/min as the last
+time.</p>
+
+<p>Storage prices still varies a lot, but as last time, I decide to
+take a reasonable big and cheap hard drive, and double its price to
+include the surrounding costs into account. A 10 TB disk cost less
+than 4500 NOK / 450 EUR these days, and doubling it give 9000 NOK per
+10 TB.</p>
+
+<p>So, with the parameters in place, lets update the old table
+estimating cost for calls in a given year:</p>
+
+<table border="1">
+<tr><th>Year</th><th>Call minutes</th><th>Size</th><th>Price in NOK / EUR</th></tr>
+<tr><td>2005</td><td align="right">24 000 000 000</td><td align="right">1.3 PiB</td><td align="right">1 170 000 / 117 000</td></tr>
+
+<tr><td>2012</td><td align="right">18 000 000 000</td><td align="right">1.0 PiB</td><td align="right">900 000 / 90 000</td></tr>
+
+<tr><td>2013</td><td align="right">17 000 000 000</td><td align="right">950 TiB</td><td align="right">855 000 / 85 500</td></tr>
+
+<tr><td>2018</td><td align="right">7 976 244 000</td><td align="right">445 TiB</td><td align="right">401 100 / 40 110</td></tr>
+</table>
+
+<p>Both the cost of storage and the number of phone call minutes have
+dropped since the last time, bringing the cost down to a level where I
+guess even small organizations can afford to store the audio recording
+from every phone call taken in a year in Norway. Of course, this is
+just the cost of buying the storage equipment. Maintenance, need to
+be included as well, but the volume of a single year is about a single
+rack of hard drives, so it is not much more than I could fit in my own
+home. Wonder how much the electricity bill would raise if I had that
+kind of storage? I doubt it would be more than a few tens of thousand
+NOK per year.</p>
