-               <description>&lt;p&gt;So far, at least hydro-electric power, coal power, wind power,
-solar power, and wood power are well known.  Until a few days ago, I
-had never heard of a stone power.  Then I learn about a quarry in a
-mountain in
-&lt;a href=&quot;https://en.wikipedia.org/wiki/Bremanger&quot;&gt;Bremanger&lt;/a&gt; i
-Norway, where
-&lt;a href=&quot;https://www.bontrup.com/en/activities/raw-materials/bremanger-quarry/&quot;&gt;the
-Bremanger Quarry&lt;/a&gt; company is extracting stone and dumping the stone
-into a shaft leading to its shipping harbour.  This downward movement
-in this shaft is used to produce electricity.  In short, it is using
-falling rocks instead of falling water to produce electricity, and
-according to its own statements it is producing more power than it is
-using, and selling the surplus electricity to the Norwegian power
-grid.  I find the concept truly amazing.  Is this the worlds only
-stone power plant?&lt;/p&gt;

+menneskerettighetserklæring&lt;/a&gt; artikkel 13 første punkt lyder som
+følger:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;
+Enhver har rett til å bevege seg fritt og til fritt å velge
+oppholdssted innenfor en stats grenser.
+&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;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 &amp;mdash; 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.&lt;/p&gt;
+
+&lt;p&gt;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
+&lt;a href=&quot;https://www.dagbladet.no/kultur/kontantlost-diktatur/70543434&quot;&gt;kontantløst
+diktatur&lt;/a&gt; som venter oss hvis mange nok slutter å insistere på å
+betale med kontanter.  Jeg anbefaler deg å lese den.&lt;/p&gt;
+
+&lt;p&gt;Som vanlig, hvis du bruker Bitcoin og ønsker å vise din støtte til
+det jeg driver med, setter jeg pris på om du sender Bitcoin-donasjoner
+til min adresse
+&lt;b&gt;&lt;a href=&quot;bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&quot;&gt;15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&lt;/a&gt;&lt;/b&gt;.
+Merk, betaling med bitcoin er ikke anonymt. :)&lt;/p&gt;

-               <description>&lt;p&gt;My movie playing setup involve &lt;a href=&quot;https://kodi.tv/&quot;&gt;Kodi&lt;/a&gt;,
-&lt;a href=&quot;https://openelec.tv&quot;&gt;OpenELEC&lt;/a&gt; (probably soon to be
-replaced with &lt;a href=&quot;https://libreelec.tv/&quot;&gt;LibreELEC&lt;/a&gt;) and an
-Infocus IN76 video projector.  My projector can be controlled via both
-a infrared remote controller, and a RS-232 serial line.  The vendor of
-my projector, &lt;a href=&quot;https://www.infocus.com/&quot;&gt;InFocus&lt;/a&gt;, had been
-sensible enough to document the serial protocol in its user manual, so
-it is easily available, and I used it some years ago to write
-&lt;a href=&quot;https://github.com/petterreinholdtsen/infocus-projector-control&quot;&gt;a
-small script to control the projector&lt;/a&gt;.  For a while now, I longed
-for a setup where the projector was controlled by Kodi, for example in
-such a way that when the screen saver went on, the projector was
-turned off, and when the screen saver exited, the projector was turned
-on again.&lt;/p&gt;
-
-&lt;p&gt;A few days ago, with very good help from parts of my family, I
-managed to find a Kodi Add-on for controlling a Epson projector, and
-got in touch with its author to see if we could join forces and make a
-Add-on with support for several projectors.  To my pleasure, he was
-positive to the idea, and we set out to add InFocus support to his
-add-on, and make the add-on suitable for the official Kodi add-on
-repository.&lt;/p&gt;
-
-&lt;p&gt;The Add-on is now working (for me, at least), with a few minor
-adjustments.  The most important change I do relative to the master
-branch in the github repository is embedding the
-&lt;a href=&quot;https://github.com/pyserial/pyserial&quot;&gt;pyserial module&lt;/a&gt; in
-the add-on.  The long term solution is to make a &quot;script&quot; type
-pyserial module for Kodi, that can be pulled in as a dependency in
-Kodi.  But until that in place, I embed it.&lt;/p&gt;
-
-&lt;p&gt;The add-on can be configured to turn on the projector when Kodi
-starts, off when Kodi stops as well as turn the projector off when the
-screensaver start and on when the screesaver stops.  It can also be
-told to set the projector source when turning on the projector.
-
-&lt;p&gt;If this sound interesting to you, check out
-&lt;a href=&quot;https://github.com/fredrik-eriksson/kodi_projcontrol&quot;&gt;the
-project github repository&lt;/a&gt;.  Perhaps you can send patches to
-support your projector too?  As soon as we find time to wrap up the
-latest changes, it should be available for easy installation using any
-Kodi instance.&lt;/p&gt;
-
-&lt;p&gt;For future improvements, I would like to add projector model
-detection and the ability to adjust the brightness level of the
-projector from within Kodi.  We also need to figure out how to handle
-the cooling period of the projector.  My projector refuses to turn on
-for 60 seconds after it was turned off.  This is not handled well by
-the add-on at the moment.&lt;/p&gt;

+               <description>&lt;p&gt;Yesterday, I had the pleasure of watching on Frikanalen the OWASP
+talk by Scott Helme titled
+&quot;&lt;a href=&quot;https://frikanalen.no/video/626080/&quot;&gt;What We’ve Learned From
+Billions of Security Reports&lt;/a&gt;&quot;.  I had not heard of the
+&lt;a href=&quot;https://en.wikipedia.org/wiki/Content_Security_Policy&quot;&gt;Content
+Security Policy standard&lt;/a&gt; nor its ability to &quot;call home&quot; when a
+browser detect a policy breach (I do not follow web page design
+development much these days), and found the talk very illuminating.&lt;/p&gt;
+
+&lt;p&gt;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 &quot;only
+local content&quot; policy despite web designers urge to fetch programs
+from random sites on the Internet, like the one
+&lt;a href=&quot;https://securityaffairs.co/wordpress/68966/hacking/browsealoud-plugin-hack.html&quot;&gt;enabling
+the attack&lt;/a&gt; reported by Scott Helme earlier this year.&lt;/p&gt;
+
+&lt;p&gt;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
+&lt;a href=&quot;https://www.w3.org/TR/CSP/&quot;&gt;standardized under W3C&lt;/a&gt; these
+days, and is supposed by most web browsers&lt;/p&gt;
+
+&lt;p&gt;I managed to find &lt;a href=&quot;https://github.com/mozilla/django-csp&quot;&gt;a
+Django middleware for implementing CSP&lt;/a&gt; and was happy to discover
+it was already in Debian.  I plan to use it to add CSP support to the
+Frikanalen web site soon.&lt;/p&gt;

-tid var det rett frem å ta vare på et TV-program en ønsket å kunne se
-senere, uten å være avhengig av at programmet ble sendt på nytt.
-Kanskje ønsket en å se programmet på hytten der det ikke var
-TV-signal, eller av andre grunner ha det tilgjengelig for fremtidig
-fornøyelse.  Dette er blitt vanskeligere med introduksjon av
-digital-TV og webstreaming, der opptak til harddisk er utenfor de
-flestes kontroll hvis de bruker ufri programvare og bokser kontrollert
-av andre.  Men for NRK her i Norge, finnes det heldigvis flere fri
-programvare-alternativer, som jeg har
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Hvordan_enkelt_laste_ned_filmer_fra_NRK.html&quot;&gt;skrevet&lt;/a&gt;
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Hvordan_enkelt_laste_ned_filmer_fra_NRK_med_den__nye__l_sningen.html&quot;&gt;om&lt;/a&gt;
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Nedlasting_fra_NRK__som_Matroska_med_undertekster.html&quot;&gt;før&lt;/a&gt;.
-Så lenge kilden for nedlastingen er lovlig lagt ut på nett (hvilket
-jeg antar NRK gjør), så er slik lagring til privat bruk også lovlig i
-Norge.&lt;/p&gt;
-
-&lt;p&gt;Sist jeg så på saken, i 2016, nevnte jeg at
-&lt;a href=&quot;https://rg3.github.com/youtube-dl/&quot;&gt;youtube-dl&lt;/a&gt; ikke kunne
-bake undertekster fra NRK inn i videofilene, og at jeg derfor
-foretrakk andre alternativer.  Nylig oppdaget jeg at dette har endret
-seg.  Fordelen med youtube-dl er at den er tilgjengelig direkte fra
-Linux-distribusjoner som &lt;a href=&quot;https://www.debian.org/&quot;&gt;Debian&lt;/a&gt;
-og &lt;a href=&quot;https://www.ubuntu.com/&quot;&gt;Ubuntu&lt;/a&gt;, slik at en slipper å
-finne ut selv hvordan en skal få dem til å virke.&lt;/p&gt;
-
-&lt;p&gt;For å laste ned et NRK-innslag med undertekster, og få den norske
-underteksten pakket inn i videofilen, så kan følgende kommando
-brukes:&lt;/p&gt;
-
-&lt;p&gt;&lt;pre&gt;

+               <description>&lt;p&gt;If you read my blog regularly, you probably know I am involved in
+running and developing the &lt;a href=&quot;https://frikanalen.no/&quot;&gt;Norwegian
+TV channel Frikanalen&lt;/a&gt;.  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
+&lt;a href=&quot;https://kodi.tv/addon/plugins-video-add-ons/frikanalen-nett-tv&quot;&gt;new
+and improved version 0.0.3 Frikanalen addon&lt;/a&gt; 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 &lt;a href=&quot;https://casparcg.com/&quot;&gt;CasparCG&lt;/a&gt;
+output look like.  The alternative is the SD video stream, generated
+using MLT.  CasparCG is controlled by our
+&lt;a href=&quot;https://github.com/Frikanalen/mltplayout/&quot;&gt;mltplayout
+server&lt;/a&gt; which instead of talking to mlt is giving PLAY instructions
+to the CasparCG server when it is time to start a new program.&lt;/p&gt;
+
+&lt;p&gt;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 &lt;a href=&quot;https://www.nuug.no/&quot;&gt;NUUG&lt;/a&gt;,
+&lt;a href=&quot;https://www.debconf.org/&quot;&gt;Debconf&lt;/a&gt;, Makercon, and TED,
+but there are also some periods with
+&lt;a href=&quot;https://www.empo.no/&quot;&gt;EMPT TV&lt;/a&gt; and
+&lt;a href=&quot;https://www.p7.no/&quot;&gt;P7&lt;/a&gt;.

 
 

-&lt;p&gt;URL-eksemplet er dagens toppsak på tv.nrk.no.  Resultatet er en
-MP4-fil med filmen og undertekster som kan spilles av med VLC.  Merk
-at VLC ikke viser frem undertekster før du aktiverer dem.  For å gjøre
-det, høyreklikk med musa i fremviservinduet, velg menyvalget for
-undertekst og så norsk språk.  Jeg testet også &#39;--write-auto-sub&#39;,
-men det kommandolinjeargumentet ser ikke ut til å fungere, så jeg
-endte opp med settet med argumentlisten over, som jeg fant i en
-feilrapport i youtube-dl-prosjektets samling over feilrapporter.&lt;/p&gt;
-
-&lt;p&gt;Denne støtten i youtube-dl gjør det svært enkelt å lagre
-NRK-innslag, det være seg nyheter, filmer, serier eller dokumentater,
-for å ha dem tilgjengelig for fremtidig referanse og bruk, uavhengig
-av hvor lenge innslagene ligger tilgjengelig hos NRK.  Så får det ikke
-hjelpe at NRKs jurister mener at det er
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Best___ikke_fortelle_noen_at_streaming_er_nedlasting___.html&quot;&gt;vesensforskjellig
-å legge tilgjengelig for nedlasting og for streaming&lt;/a&gt;, når det rent
-teknisk er samme sak.&lt;/p&gt;
-
-&lt;p&gt;Programmet youtube-dl støtter også en rekke andre nettsteder, se

-melder i dag at flertallet i Familie- og kulturkomiteen på Stortinget
-har bestemt seg for å introdusere en ny sensurinfrastruktur i Norge.
-Fra før har Norge en «frivillig» sensurinfrastruktur basert på
-DNS-navn, der de største ISP-ene basert på en liste med DNS-navn
-forgifter DNS-svar og omdirigerer til et annet IP-nummer enn det som
-ligger i DNS.  Nå kommer altså IP-basert omdirigering i tillegg.  Når
-infrastrukturen er på plass, er sensur av IP-adresser redusert et
-spørsmål om hvilke IP-nummer som skal blokkeres.  Listen over
-IP-adresser vil naturligvis endre seg etter hvert som myndighetene
-endrer seg.  Det er ingen betryggende tanke.&lt;/p&gt;

+               <description>&lt;p&gt;As part of my involvement in
+&lt;a href=&quot;https://gitlab.com/OsloMet-ABI/nikita-noark5-core&quot;&gt;the Nikita
+archive API project&lt;/a&gt;, I&#39;ve been importing a fairly large lump of
+emails into a test instance of the archive to see how well this would
+go.  I picked a subset of &lt;a href=&quot;https://notmuchmail.org/&quot;&gt;my
+notmuch email database&lt;/a&gt;, all public emails sent to me via
+@lists.debian.org, giving me a set of around 216 000 emails to import.
+In the process, I had a look at the various attachments included in
+these emails, to figure out what to do with attachments, and noticed
+that one of the most common attachment formats do not have
+&lt;a href=&quot;https://www.iana.org/assignments/media-types/media-types.xhtml&quot;&gt;an
+official MIME type&lt;/a&gt; registered with IANA/IETF.  The output from
+diff, ie the input for patch, is on the top 10 list of formats
+included in these emails.  At the moment people seem to use either
+text/x-patch or text/x-diff, but neither is officially registered.  It
+would be better if one official MIME type were registered and used
+everywhere.&lt;/p&gt;

-               <description>&lt;p&gt;Brevpost er beskyttet av straffelovens bestemmelse som gjør det
-kriminelt å åpne andres brev.  Dette følger av (ny) straffelovs
-&lt;a href=&quot;https://lovdata.no/dokument/NL/lov/2005-05-20-28/§205&quot;&gt;§ 205
-(Krenkelse av retten til privat kommunikasjon)&lt;/a&gt;, som sier at «Med
-bot eller fengsel inntil 2 år straffes den som uberettiget ...  c)
-åpner brev eller annen lukket skriftlig meddelelse som er adressert
-til en annen, eller på annen måte skaffer seg uberettiget tilgang til
-innholdet.» Dette gjelder såvel postbud som alle andre som har
-befatning med brevet etter at avsender har befatning med et lukket
-brev. Tilsvarende står også tidligere utgaver av den norske
-straffeloven.&lt;/p&gt;
-
-&lt;p&gt;Når en registrerer seg på usikre digitale postkasseløsningene, som
-f.eks. Digipost og e-Boks, og slik tar disse i bruk, så gir en de som
-står bak løsningene tillatelse til å åpne sine brev.  Dette er
-nødvendig for at innholdet i digital post skal kunne vises frem til
-mottaker via tjenestens websider.  Dermed gjelder ikke straffelovens
-paragraf om forbud mot å åpne brev, da tilgangen ikke lenger er
-uberettiget.  En gir altså fremmede tilgang til å lese sin
-korrespondanse.  I tillegg vil bruk av slike usikre digitale
-postbokser føre til at det blir registrert når du leser brevene, hvor
-du befinner deg (vha. tilkoblingens IP-adresse), hvilket utstyr du
-bruker og en rekke annen personlig informasjon som ikke er
-tilgjengelig når papirpost brukes.  Jeg foretrekker at det er
-lovmessig beskyttelse av min korrespondanse, som jo inneholder privat
-og personlig informasjon.  Det bidrar til litt bedre vern av personlig
-integritet i dagens norske samfunn.&lt;/p&gt;

+               <description>&lt;p&gt;&lt;img src=&quot;http://people.skolelinux.org/pere/blog/images/2018-10-22-audmes-measure-speakers.png&quot; align=&quot;right&quot; width=&quot;40%&quot;/&gt;&lt;/p&gt;
+
+&lt;p&gt;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&#39;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
+&lt;a href=&quot;https://www.diyaudioandvideo.com/Tutorial/SpeakerResponseTesting/&quot;&gt;Speaker
+Testing and Analysis&lt;/a&gt; describing how to test speakers, and it listing
+several software options, among them
+&lt;a href=&quot;https://sourceforge.net/projects/audmes/&quot;&gt;AUDio MEasurement
+System (AUDMES)&lt;/a&gt;.  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
+&lt;a href=&quot;http://novo.press/understanding-speaker-specifications-and-frequency-response/&quot;&gt;Understanding
+Speaker Specifications and Frequency Response&lt;/a&gt; and an article from
+ecoustics on
+&lt;a href=&quot;https://www.ecoustics.com/articles/understanding-speaker-frequency-response/&quot;&gt;Understanding
+Speaker Frequency Response&lt;/a&gt;, 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.&lt;/p&gt;
+
+&lt;p&gt;The first hurdle was that AUDMES hadn&#39;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.&lt;/p&gt;
+
+&lt;p&gt;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
+&lt;a href=&quot;http://freehearingtestsoftware.com&quot;&gt;Free Hearing Test
+Software&lt;/a&gt;, 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.&lt;/p&gt;
+
+&lt;p&gt;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
+&lt;a href=&quot;https://bugs.debian.org/910876&quot;&gt;include in Debian&lt;/a&gt;?  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
+&lt;a href=&quot;https://www.roomeqwizard.com/&quot;&gt;REW&lt;/a&gt;, but I want something
+that can be developed also when the vendor looses interest.&lt;/p&gt;

+               <link>http://people.skolelinux.org/pere/blog/Web_browser_integration_of_VLC_with_Bittorrent_support.html</link>
+               <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Web_browser_integration_of_VLC_with_Bittorrent_support.html</guid>
+                <pubDate>Sun, 21 Oct 2018 09:50:00 +0200</pubDate>
+               <description>&lt;p&gt;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
+&lt;a href=&quot;https://www.nrk.no/&quot;&gt;NRK&lt;/a&gt;, Linux distributors like
+&lt;a href=&quot;https://www.debian.org/&quot;&gt;Debian&lt;/a&gt; and
+&lt;a href=&quot;https://www.ubuntu.com/&quot;&gt;Ubuntu&lt;/a&gt;, and of course the
+&lt;a href=&quot;https://archive.org/&quot;&gt;Internet archive&lt;/A&gt;.
+
+&lt;p&gt;Almost a month ago
+&lt;a href=&quot;https://tracker.debian.org/pkg/vlc-plugin-bittorrent&quot;&gt;a new
+package adding Bittorrent support to VLC&lt;/a&gt; became available in
+Debian testing and unstable.  To test it, simply install it like
+this:&lt;/p&gt;

 
 

-&lt;p&gt;&lt;blockquote&gt;
-&lt;p&gt;&quot;An American president does not lead the Free World by
-congratulating dictators on winning sham elections.&quot;&lt;/p&gt;
-&lt;/blockquote&gt;&lt;/p&gt;
+&lt;p&gt;&lt;pre&gt;
+apt install vlc-plugin-bittorrent
+&lt;/pre&gt;&lt;/p&gt;

 
 

-&lt;p&gt;While I totally agree with the senator here, the way the quote is
-phrased make me suspect that he is unaware of the simple fact that USA
-have not lead the Free World since at least before its government
-&lt;a href=&quot;https://en.wikipedia.org/wiki/Maher_Arar&quot;&gt;kidnapped a
-completely innocent Canadian citizen in transit on his way home to
-Canada via John F. Kennedy International Airport in September 2002 and
-sent him to be tortured in Syria for a year&lt;/a&gt;.&lt;/p&gt;
+&lt;p&gt;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
+&lt;a href=&quot;https://archive.org/details/CopyingIsNotTheft1080p&quot;&gt;Internet
+Archive page with movies&lt;/a&gt; using a web browser and click on the
+torrent link to start streaming the movie.&lt;/p&gt;
+
+&lt;p&gt;Note, there is still some misfeatures in the plugin.  One is the
+fact that it will hang and
+&lt;a href=&quot;https://github.com/johang/vlc-bittorrent/issues/13&quot;&gt;block VLC
+from exiting until the torrent streaming starts&lt;/a&gt;.  Another is the
+fact that it
+&lt;a href=&quot;https://github.com/johang/vlc-bittorrent/issues/9&quot;&gt;will pick
+and play a random file in a multi file torrent&lt;/a&gt;.  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.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;

 
 

-&lt;p&gt;USA might be running ahead, but the path they are taking is not the
-one taken by any Free World.&lt;/p&gt;

-               <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Facebooks_ability_to_sell_your_personal_information_is_the_real_Cambridge_Analytica_scandal.html</guid>
-                <pubDate>Wed, 21 Mar 2018 16:30:00 +0100</pubDate>
-               <description>&lt;p&gt;So, Cambridge Analytica is getting some well deserved criticism for
-(mis)using information it got from Facebook about 50 million people,
-mostly in the USA.  What I find a bit surprising, is how little
-criticism Facebook is getting for handing the information over to
-Cambridge Analytica and others in the first place.  And what about the
-people handing their private and personal information to Facebook?
-And last, but not least, what about the government offices who are
-handing information about the visitors of their web pages to Facebook?
-No-one who looked at the terms of use of Facebook should be surprised
-that information about peoples interests, political views, personal
-lifes and whereabouts would be sold by Facebook.&lt;/p&gt;
-
-&lt;p&gt;What I find to be the real scandal is the fact that Facebook is
-selling your personal information, not that one of the buyers used it
-in a way Facebook did not approve when exposed.  It is well known that
-Facebook is selling out their users privacy, but a scandal
-nevertheless.  Of course the information provided to them by Facebook
-would be misused by one of the parties given access to personal
-information about the millions of Facebook users.  Collected
-information will be misused sooner or later.  The only way to avoid
-such misuse, is to not collect the information in the first place.  If
-you do not want Facebook to hand out information about yourself for
-the use and misuse of its customers, do not give Facebook the
-information.&lt;/p&gt;
-
-&lt;p&gt;Personally, I would recommend to completely remove your Facebook
-account, and take back some control of your personal information.
-&lt;a href=&quot;https://www.theguardian.com/technology/2018/mar/19/how-to-protect-your-facebook-privacy-or-delete-yourself-completely&quot;&gt;According
-to The Guardian&lt;/a&gt;, it is a bit hard to find out how to request
-account removal (and not just &#39;disabling&#39;).  You need to
-&lt;a href=&quot;https://www.facebook.com/help/224562897555674?helpref=faq_content&quot;&gt;visit
-a specific Facebook page&lt;/a&gt; and click on &#39;let us know&#39; on that page
-to get to &lt;a href=&quot;https://www.facebook.com/help/delete_account&quot;&gt;the
-real account deletion screen&lt;/a&gt;.  Perhaps something to consider?  I
-would not trust the information to really be deleted (who knows,
-perhaps NSA, GCHQ and FRA already got a copy), but it might reduce the
-exposure a bit.&lt;/p&gt;
-
-&lt;p&gt;If you want to learn more about the capabilities of Cambridge
-Analytica, I recommend to see the video recording of the one hour talk
-Paul-Olivier Dehaye gave to &lt;a href=&quot;&quot;&gt;NUUG&lt;/a&gt; last april about
-&lt;a href=&quot;https://www.nuug.no/aktiviteter/20170404-big-data-psychometric/&quot;&gt;
-Data collection, psychometric profiling and their impact on
-politics&lt;/a&gt;.&lt;/p&gt;
-
-&lt;p&gt;And if you want to communicate with your friends and loved ones,
-use some end-to-end encrypted method like
-&lt;a href=&quot;https://www.signal.org/&quot;&gt;Signal&lt;/a&gt; or
-&lt;a href=&quot;https://ring.cx/&quot;&gt;Ring&lt;/a&gt;, and stop sharing your private
-messages with strangers like Facebook and Google.&lt;/p&gt;

-               <description>&lt;p&gt;I går kom det nok et argument for å holde seg unna det norske
-helsevesenet.  Da annonserte et stortingsflertall, bestående av Høyre,
-Arbeiderpartiet, Fremskrittspartiet og Venstre, at de går inn for å
-samle inn og lagre DNA-prøver fra hele befolkningen i Norge til evig
-tid.  Endringen gjelder innsamlede blodprøver fra nyfødte i Norge.
-Det vil dermed ta litt tid før en har hele befolkningen, men det er
-dit vi havner gitt nok tid.  I dag er det nesten hundre prosent
-oppslutning om undersøkelsen som gjøres like etter fødselen, på
-bakgrunn av blodprøven det er snakk om å lagre, for å oppdage endel
-medfødte sykdommer.  Blodprøven lagres i dag i inntil seks år.

-flertallsinnstilling&lt;/a&gt; er at tidsbegrensingen skal fjernes, og mener
-at tidsubegrenset lagring ikke vil påvirke oppslutningen om
-undersøkelsen.&lt;/p&gt;

+               <description>&lt;p&gt;I have  earlier covered the basics of trusted timestamping using the
+&#39;openssl ts&#39; client.  See blog post for
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Public_Trusted_Timestamping_services_for_everyone.html&quot;&gt;2014&lt;/a&gt;,
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/syslog_trusted_timestamp___chain_of_trusted_timestamps_for_your_syslog.html&quot;&gt;2016&lt;/a&gt;
+and
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Idea_for_storing_trusted_timestamps_in_a_Noark_5_archive.html&quot;&gt;2017&lt;/a&gt;
+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
+&lt;a href=&quot;https://dev.entrouvert.org/projects/python-rfc3161&quot;&gt;the
+rfc3161 library&lt;/a&gt; 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
+&lt;a href=&quot;https://github.com/trbs/rfc3161ng/&quot;&gt;the rfc3161ng library&lt;/a&gt;,
+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
+&lt;a href=&quot;https://tracker.debian.org/pkg/python-rfc3161ng&quot;&gt;available in
+Debian&lt;/a&gt;, and a few days ago it entered Debian unstable and testing.&lt;/p&gt;
+
+&lt;p&gt;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:&lt;/p&gt;
+
+&lt;pre&gt;
+#!/usr/bin/python3
+
+&quot;&quot;&quot;
+
+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.
+
+&quot;&quot;&quot;
+
+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(&#39;https://freetsa.org/files/tsa.crt&#39;, cert_f)
+        ca_data_data = fetch(&#39;https://freetsa.org/files/cacert.pem&#39;, ca_f)
+
+        # Then timestamp the message
+        timestamper = \
+            rfc3161ng.RemoteTimestamper(&#39;http://freetsa.org/tsr&#39;,
+                                        certificate=certificate_data)
+        data = b&quot;Python forever!\n&quot;
+        tsr = timestamper(data=data, return_tsr=True)
+
+        # Finally, convert message and response to something &#39;openssl ts&#39; can verify
+        store(msg_f, data)
+        store(tsr_f, pyasn1.codec.der.encoder.encode(tsr))
+        args = [&quot;openssl&quot;, &quot;ts&quot;, &quot;-verify&quot;,
+                &quot;-data&quot;, msg_f.name,
+               &quot;-in&quot;, tsr_f.name,
+               &quot;-CAfile&quot;, ca_f.name,
+                &quot;-untrusted&quot;, cert_f.name]
+        subprocess.check_call(args)
+
+if &#39;__main__&#39; == __name__:
+   main()
+&lt;/pre&gt;
+
+&lt;p&gt;The code fetches the required certificates, store them as temporary
+files, timestamp a simple message, store the message and timestamp to
+disk and ask &#39;openssl ts&#39; to verify the timestamp.  A timestamp is
+around 1.5 kiB in size, and should be fairly easy to store for future
+use.&lt;/p&gt;

-  &lt;p&gt;«Datatilsynet mener forslaget ikke i tilstrekkelig grad
-  synliggjør hvilke etiske og personvernmessige utfordringer som må
-  diskuteres før en etablerer en nasjonal biobank med blodprøver fra
-  hele befolkningen.»&lt;/p&gt;
-  
-&lt;/blockquote&gt;&lt;/p&gt;
-
-&lt;p&gt;Det er flere historier om hvordan innsamlet biologisk materiale har
-blitt brukt til andre formål enn de ble innsamlet til, og historien om
-&lt;a href=&quot;https://www.aftenposten.no/norge/i/Ql0WR/Na-ma-Folkehelsa-slette-uskyldiges-DNA-info&quot;&gt;folkehelseinstituttets
-lagring på vegne av politiet (Kripos) av innsamlet biologisk materiale
-og DNA-informasjon i strid med loven&lt;/a&gt; viser at en ikke kan være
-trygg på at lover og intensjoner beskytter de som blir berørt mot
-misbruk av slik privat og personlig informasjon.&lt;/p&gt;
-
-&lt;p&gt;Det er verdt å merke seg at det kan forskes på de innsamlede
-blodprøvene uten samtykke fra den det gjelder (eller foreldre når det
-gjelder barn), etter en lovendring for en stund tilbake, med mindre
-det er sendt inn skjema der en reserverer seg mot forskning uten
-samtykke.  Skjemaet er tilgjengelig fra
-&lt;a href=&quot;https://www.fhi.no/arkiv/publikasjoner/for-pasienter-skjema-for-reservasjo/&quot;&gt;folkehelseinstituttets
-websider&lt;/a&gt;, og jeg anbefaler, uavhengig av denne saken, varmt alle å
-sende inn skjemaet for å dokumentere hvor mange som ikke synes det er
-greit å fjerne krav om samtykke.&lt;/p&gt;
-
-&lt;p&gt;I tillegg bør en kreve destruering av alt biologisk materiale som
-er samlet inn om en selv, for å redusere eventuelle negative
-konsekvenser i fremtiden når materialet kommer på avveie eller blir
-brukt uten samtykke, men det er så vidt jeg vet ikke noe system for

-               <description>&lt;p&gt;I am working on publishing yet another book related to Creative
-Commons.  This time it is a book filled with interviews and histories
-from those around the globe making a living using Creative
-Commons.&lt;/p&gt;
-
-&lt;p&gt;Yesterday, after many months of hard work by several volunteer
-translators, the first draft of a Norwegian Bokmål edition of the book
-&lt;a href=&quot;https://madewith.cc&quot;&gt;Made with Creative Commons from 2017&lt;/a&gt;
-was complete.  The Spanish translation is also complete, while the
-Dutch, Polish, German and Ukraine edition need a lot of work.  Get in
-touch if you want to help make those happen, or would like to
-translate into your mother tongue.&lt;/p&gt;
-
-&lt;p&gt;The whole book project started when
-&lt;a href=&quot;http://gwolf.org/node/4102&quot;&gt;Gunnar Wolf announced&lt;/a&gt; that he
-was going to make a Spanish edition of the book.  I noticed, and
-offered some input on how to make a book, based on my experience with
-translating the
-&lt;a href=&quot;https://www.lulu.com/shop/lawrence-lessig/fri-kultur/paperback/product-22441576.html&quot;&gt;Free
-Culture&lt;/a&gt; and
-&lt;a href=&quot;https://debian-handbook.info/get/#norwegian&quot;&gt;The Debian
-Administrator&#39;s Handbook&lt;/a&gt; books to Norwegian Bokmål.  To make a
-long story short, we ended up working on a Bokmål edition, and now the
-first rough translation is complete, thanks to the hard work of
-Ole-Erik Yrvin, Ingrid Yrvin, Allan Nordhøy and myself.  The first
-proof reading is almost done, and only the second and third proof
-reading remains.  We will also need to translate the 14 figures and
-create a book cover.  Once it is done we will publish the book on
-paper, as well as in PDF, ePub and possibly Mobi formats.&lt;/p&gt;
-
-&lt;p&gt;The book itself originates as a manuscript on Google Docs, is
-downloaded as ODT from there and converted to Markdown using pandoc.
-The Markdown is modified by a script before is converted to DocBook
-using pandoc.  The DocBook is modified again using a script before it
-is used to create a Gettext POT file for translators.  The translated
-PO file is then combined with the earlier mentioned DocBook file to
-create a translated DocBook file, which finally is given to dblatex to
-create the final PDF.  The end result is a set of editions of the
-manuscript, one English and one for each of the translations.&lt;/p&gt;
-
-&lt;p&gt;The translation is conducted using
-&lt;a href=&quot;https://hosted.weblate.org/projects/madewithcc/translation/&quot;&gt;the
-Weblate web based translation system&lt;/a&gt;.  Please have a look there
-and get in touch if you would like to help out with proof
-reading. :)&lt;/p&gt;

+               <description>&lt;p&gt;A few days, I rescued a Windows victim over to Debian.  To try to
+rescue the remains, I helped set up automatic sync with Google Drive.
+I did not find any sensible Debian package handling this
+automatically, so I rebuild the grive2 source from
+&lt;a href=&quot;http://www.webupd8.org/&quot;&gt;the Ubuntu UPD8 PPA&lt;/a&gt; to do the
+task and added a autostart desktop entry and a small shell script to
+run in the background while the user is logged in to do the sync.
+Here is a sketch of the setup for future reference.&lt;/p&gt;
+
+&lt;p&gt;I first created &lt;tt&gt;~/googledrive&lt;/tt&gt;, entered the directory and
+ran &#39;&lt;tt&gt;grive -a&lt;/tt&gt;&#39; to authenticate the machine/user.  Next, I
+created a autostart hook in &lt;tt&gt;~/.config/autostart/grive.desktop&lt;/tt&gt;
+to start the sync when the user log in:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+[Desktop Entry]
+Name=Google drive autosync
+Type=Application
+Exec=/home/user/bin/grive-sync
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;Finally, I wrote the &lt;tt&gt;~/bin/grive-sync&lt;/tt&gt; script to sync
+~/googledrive/ with the files in Google Drive.&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+#!/bin/sh
+set -e
+cd ~/
+cleanup() {
+    if [ &quot;$syncpid&quot; ] ; then
+        kill $syncpid
+    fi
+}
+trap cleanup EXIT INT QUIT
+/usr/lib/grive/grive-sync.sh listen googledrive 2&gt;&amp;1 | sed &quot;s%^%$0:%&quot; &amp;
+syncpdi=$!
+while true; do
+    if ! xhost &gt;/dev/null 2&gt;&amp;1 ; then
+        echo &quot;no DISPLAY, exiting as the user probably logged out&quot;
+        exit 1
+    fi
+    if [ ! -e /run/user/1000/grive-sync.sh_googledrive ] ; then
+        /usr/lib/grive/grive-sync.sh sync googledrive
+    fi
+    sleep 300
+done 2&gt;&amp;1 | sed &quot;s%^%$0:%&quot;
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;Feel free to use the setup if you want.  It can be assumed to be
+GNU GPL v2 licensed (or any later version, at your leisure), but I
+doubt this code is possible to claim copyright on.&lt;/p&gt;

-               <description>&lt;p&gt;Today I was pleasantly surprised to discover my operating system of
-choice, Debian, was used in the info screens on the subway stations.
-While passing Nydalen subway station in Oslo, Norway, I discovered the
-info screen booting with some text scrolling.  I was not quick enough
-with my camera to be able to record a video of the scrolling boot
-screen, but I did get a photo from when the boot got stuck with a
-corrupt file system:
-
-&lt;p align=&quot;center&quot;&gt;&lt;a href=&quot;http://people.skolelinux.org/pere/blog/images/2018-03-02-ruter-debian-lenny.jpeg&quot;&gt;&lt;img align=&quot;center&quot; width=&quot;40%&quot; src=&quot;http://people.skolelinux.org/pere/blog/images/2018-03-02-ruter-debian-lenny.jpeg&quot; alt=&quot;[photo of subway info screen]&quot;&gt;&lt;/a&gt;&lt;/p&gt;
-
-&lt;p&gt;While I am happy to see Debian used more places, some details of the
-content on the screen worries me.&lt;/p&gt;
-
-&lt;p&gt;The image show the version booting is &#39;Debian GNU/Linux lenny/sid&#39;,
-indicating that this is based on code taken from Debian Unstable/Sid
-after Debian Etch (version 4) was released 2007-04-08 and before
-Debian Lenny (version 5) was released 2009-02-14.  Since Lenny Debian
-has released version 6 (Squeeze) 2011-02-06, 7 (Wheezy) 2013-05-04, 8
-(Jessie) 2015-04-25 and 9 (Stretch) 2017-06-15, according to
-&lt;a href=&quot;https://en.wikipedia.org/wiki/Debian_version_history&quot;&gt;a Debian
-version history on Wikpedia&lt;/a&gt;.  This mean the system is running
-around 10 year old code, with no security fixes from the vendor for
-many years.&lt;/p&gt;
-
-&lt;p&gt;This is not the first time I discover the Oslo subway company,
-Ruter, running outdated software.  In 2012,
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Er_billettautomatene_til_kollektivtrafikken_i_Oslo_uten_sikkerhetsoppdateringer_.html&quot;&gt;I
-discovered the ticket vending machines were running Windows 2000&lt;/a&gt;,
-and this was
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Fortsatt_ingen_sikkerhetsoppdateringer_for_billettautomatene_til_kollektivtrafikken_i_Oslo_.html&quot;&gt;still
-the case in 2016&lt;/a&gt;.  Given the response from the responsible people
-in 2016, I would assume the machines are still running unpatched
-Windows 2000.  Thus, an unpatched Debian setup come as no surprise.&lt;/p&gt;

+               <description>&lt;p&gt;It would come as no surprise to anyone that I am interested in
+bitcoins and virtual currencies.  I&#39;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.&lt;/p&gt;
+
+&lt;p&gt;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
+&lt;a href=&quot;http://github.com/petterreinholdtsen/valutakrambod&quot;&gt;github&lt;/a&gt;.&lt;/p&gt;
+
+&lt;/p&gt;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:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+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(&quot;%-15s %s-%s: %8.3f %8.3f&quot; % (
+            service.servicename(),
+            pair[0],
+            pair[1],
+            service.rates[pair][&#39;ask&#39;],
+            service.rates[pair][&#39;bid&#39;])
+        )
+    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(&quot;Interrupted by keyboard, closing all connections.&quot;)
+            pass

+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;The library client loops over all known &quot;public&quot; 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:&lt;/p&gt;

+
+&lt;p&gt;The exchange order book is tracked in addition to the best buy/sell
+price, for those that need to know the details.&lt;/p&gt;
+
+&lt;p&gt;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 &#39;-c&#39; argument.  Without the argument the &quot;curses&quot; output
+is printed without using curses, which is useful for debugging.  The
+curses view look like this:&lt;/p&gt;

+
+&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;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&#39;ve
+implemented a trading API.  It might be the topic of a future blog
+post.&lt;/p&gt;
