Because of this, I asked the people behind it back in -November to clarify. Ann-Christine Savlid (ann-christine.savlid (at) -visma.com) replied that Visma had not applied for patent or trademark -protection for this format, and that there were no copyright based -usage limitations for the format. I urged her to make sure this was -explicitly written on the web pages and in the specification, but -unfortunately this has not happened yet. So I guess if there is -submarine patents, hidden trademarks or a will to sue for copyright -infringements, those starting to use the UsingQR format might be at -risk, but if this happen there is some legal defense in the fact that -the people behind the format claimed it was safe to do so. At least -with patents, there is always -<a href="http://www.paperspecs.com/paper-news/beware-the-qr-code-patent-trap/">a -chance of getting sued...</a></p> - -<p>I also asked if they planned to maintain the format in an -independent standard organization to give others more confidence that -they would participate in the standardization process on equal terms -with Visma, but they had no immediate plans for this. Their plan was -to work with banks to try to get more users of the format, and -evaluate the way forward if the format proved to be popular.

I -uploaded a new version which did not work quite right, but did not -have time to fix it then. This Christmas I decided to finally try to -get Creepy operational in Debian. Now a fixed version is available in -Debian unstable and testing, and almost all Debian specific patches -are now included -<a href="https://github.com/jkakavas/creepy">upstream</a>.</p> - -<p>The Creepy program visualises geolocation information fetched from -Twitter, Instagram, Flickr and Google+, and allow one to get a -complete picture of every social media message posted recently in a -given area, or track the movement of a given individual across all -these services. Earlier it was possible to use the search API of at -least some of these services without identifying oneself, but these -days it is impossible. This mean that to use Creepy, you need to -configure it to log in as yourself on these services, and provide -information to them about your search interests. This should be taken -into account when using Creepy, as it will also share information -about yourself with the services.</p> - -<p>The picture above show the twitter messages sent from (or at least -geotagged with a position from) the city centre of Oslo, the capital -of Norway. One useful way to use Creepy is to first look at -information tagged with an area of interest, and next look at all the -information provided by one or more individuals who was in the area. -I tested it by checking out which celebrity provide their location in -twitter messages by checkout out who sent twitter messages near a -Norwegian TV station, and next could track their position over time, -making it possible to locate their home and work place, among other -things.

This is a good reason to always -use encrypted connections to the Debian mirror, to make sure those -listening do not know which IP address to attack. In August, Richard -Hartmann observed that encryption was not enough, when it was possible -to interfere download size to security patches or the fact that -download took place shortly after a security fix was released, and -<a href="http://richardhartmann.de/blog/posts/2015/08/24-Tor-enabled_Debian_mirror/">proposed -to always use Tor to download packages from the Debian mirror</a>. He -was not the first to propose this, as the -<tt><a href="https://tracker.debian.org/pkg/apt-transport-tor">apt-transport-tor</a></tt> -package by Tim Retout already existed to make it easy to convince apt -to use <a href="https://www.torproject.org/">Tor</a>, but I was not -aware of that package when I read the blog post from Richard.</p> - -<p>Richard discussed the idea with Peter Palfrader, one of the Debian -sysadmins, and he set up a Tor hidden service on one of the central -Debian mirrors using the address vwakviie2ienjx6t.onion, thus making -it possible to download packages directly between two tor nodes, -making sure the network traffic always were encrypted.</p> - -<p>Here is a short recipe for enabling this on your machine, by -installing <tt>apt-transport-tor</tt> and replacing http and https -urls with tor+http and tor+https, and using the hidden service instead -of the official Debian mirror site. I recommend installing -<tt>etckeeper</tt> before you start to have a history of the changes -done in /etc/.</p> - -<blockquote><pre> -apt install apt-transport-tor -sed -i 's% http://ftp.debian.org/% tor+http://vwakviie2ienjx6t.onion/%' /etc/apt/sources.list -sed -i 's% http% tor+http%' /etc/apt/sources.list -</pre></blockquote> - -<p>If you have more sources listed in /etc/apt/sources.list.d/, run -the sed commands for these too. The sed command is assuming your are -using the ftp.debian.org Debian mirror. Adjust the command (or just -edit the file manually) to match your mirror.</p> - -<p>This work in Debian Jessie and later. Note that tools like -<tt>apt-file</tt> only recently started using the apt transport -system, and do not work with these tor+http URLs. For -<tt>apt-file</tt> you need the version currently in experimental, -which need a recent apt version currently only in unstable.

A GUI system in the isenkram package will -present a pop-up dialog when some hardware dongle supported by -relevant packages in Debian is inserted into the machine. The same -lookup mechanism to detect packages is available as command line -tools in the isenkram-cli package. In addition to mapping hardware, -it will also map kernel firmware files to packages and make it easy to -install needed firmware packages automatically. The key for this -system to work is a good way to map hardware to packages, in other -words, allow packages to announce what hardware they will work -with.</p> - -<p>I started by providing data files in the isenkram source, and -adding code to download the latest version of these data files at run -time, to ensure every user had the most up to date mapping available. -I also added support for storing the mapping in the Packages file in -the apt repositories, but did not push this approach because while I -was trying to figure out how to best store hardware/package mappings, -<a href="http://www.freedesktop.org/software/appstream/docs/">the -appstream system</a> was announced. I got in touch and suggested to -add the hardware mapping into that data set to be able to use -appstream as a data source, and this was accepted at least for the -Debian version of appstream.</p> - -<p>A few days ago using appstream in Debian for this became possible, -and today I uploaded a new version 0.20 of isenkram adding support for -appstream as a data source for mapping hardware to packages. The only -package so far using appstream to announce its hardware support is my -pymissile package. I got help from Matthias Klumpp with figuring out -how do add the required -<a href="https://appstream.debian.org/html/sid/main/metainfo/pymissile.html">metadata -in pymissile</a>.

Jeg hadde trodd det skulle ta lenger tid, da -jeg fikk beskjed om at det skulle ta seks til åtte uker. -Amazonoppføringen er et resultat av at jeg for noen uker siden -diskuterte prissetting og håndtering av profitt med forfatteren. Det -måtte avklares da bruksvilkårene til boken har krav om -ikke-kommersiell bruk. Vi ble enige om at overskuddet fra salg av -boken skal sendes til -<a href="https://creativecommons.org/">Creative Commons-stiftelsen</a>. -Med det på plass kunne jeg be -<a href="https://www.lulu.com/shop/lawrence-lessig/fri-kultur/paperback/product-22441576.html">lulu.com</a> -om å gi boken «utvidet» distribusjon. Årsaken til at -bokhandeldistribusjon var litt utfordrende er at bokhandlere krever -mulighet for profitt på bøkene de selger (selvfølgelig), og dermed -måtte de få lov til å selge til høyere pris enn lulu.com. I tillegg -er det krav om samme pris på lulu.com og i bokhandlene, dermed blir -prisen økt også hos lulu.com. Hva skulle jeg gjøre med den profitten -uten å bryte med klausulen om ikkekommersiell? Løsningen var å gi -bort profitten til CC-stiftelsen. Prisen på boken ble nesten -tredoblet, til $19.99 (ca. 160,-) pluss frakt, men synligheten øker -betraktelig når den kan finnes i katalogene til store nettbokhandlere. -Det betyr at hvis du allerede har kjøpt boken har du fått den veldig -billig, og kjøper du den nå, får du den fortsatt billig samt donerer i -tillegg noen tiere til fremme av Creative Commons.</p> - -<p>Mens jeg var i gang med å titte etter informasjon om boken -oppdaget jeg at den også var dukket opp på -<a href="https://books.google.no/books?id=uKUGCwAAQBAJ">Google -Books</a>, der en kan lese den på web. PDF-utgaven har ennå ikke -dukket opp hos <a href="https://www.nb.no/">Nasjonalbiblioteket</a>, -men det regner jeg med kommer på plass i løpet av noen uker. Boken er -heller ikke dukket opp hos -<a href="https://www.barnesandnoble.com/">Barnes & Noble</a> ennå, men -jeg antar det bare er et tidsspørsmål før dette er på plass.</p> - -<p>Boken er dessverre ikke tilgjengelig fra norske bokhandlere, og -kommer neppe til å bli det med det første. Årsaken er at for å få det -til måtte jeg personlig håndtere bestilling av bøker, hvilket jeg ikke -er interessert i å bruke tid på. Jeg kunne betalt ca 2000,- til -<a href="http://www.bokbasen.no/">den norske bokbasen</a>, en felles -database over bøker tilgjengelig for norske bokhandlere, for å få en -oppføring der, men da måtte jeg tatt imot bestillinger på epost og -sendt ut bøker selv. Det ville krevd at jeg var klar til å -sende ut bøker på kort varsel, dvs. holdt meg med ekstra bøker, -konvolutter og frimerker. Bokbasen har visst ikke opplegg for å be -bokhandlene bestille direkte via web, så jeg droppet oppføring der. -Jeg har spurt Haugen bok og Tronsmo direkte på epost om de er -interessert i å ta inn boken i sin bestillingskatalog, men ikke fått -svar, så jeg antar de ikke er interessert. Derimot har jeg fått en -hyggelig henvendelse fra Biblioteksentralen som fortalte at de har -lagt den inn i sin database slik at deres bibliotekskunder enkelt kan -bestille den via dem.</p> - -<p>Boken er i følge -<a href="http://bibsys-almaprimo.hosted.exlibrisgroup.com/primo_library/libweb/action/display.do?tabs=detailsTab&ct=display&fn=search&doc=BIBSYS_ILS71518423420002201&indx=1&recIds=BIBSYS_ILS71518423420002201&recIdxs=0&elementId=0&renderMode=poppedOut&displayMode=full&frbrVersion=&dscnt=0&tab=library_catalogue&dstmp=1448543801124&vl(freeText0)=fri%20kultur&vid=UBO&mode=Basic">Bibsys/Oria</a> -og bokdatabasen til -<a href="https://www.deich.folkebibl.no/cgi-bin/websok?tnr=1819617">Deichmanske</a> -tilgjengelig fra flere biblioteker allerede, og alle eksemplarer er -visst allerede utlånt med ventetid. Det synes jeg er veldig gledelig -å se. Jeg håper mange kommer til å lese boken. Jeg tror den er -spesielt egnet for foreldre og bekjente av oss nerder for å forklare -hva slags problemer vi ser med dagens opphavsrettsregime.</p> + Debian used in the subway info screens in Oslo, Norway + http://people.skolelinux.org/pere/blog/Debian_used_in_the_subway_info_screens_in_Oslo__Norway.html + http://people.skolelinux.org/pere/blog/Debian_used_in_the_subway_info_screens_in_Oslo__Norway.html + Fri, 2 Mar 2018 13:10:00 +0100 + <p>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: + +<p align="center"><a href="http://people.skolelinux.org/pere/blog/images/2018-03-02-ruter-debian-lenny.jpeg"><img align="center" width="40%" src="http://people.skolelinux.org/pere/blog/images/2018-03-02-ruter-debian-lenny.jpeg" alt="[photo of subway info screen]"></a></p> + +<p>While I am happy to see Debian used more places, some details of the +content on the screen worries me.</p> + +<p>The image show the version booting is 'Debian GNU/Linux lenny/sid', +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 +<a href="https://en.wikipedia.org/wiki/Debian_version_history">a Debian +version history on Wikpedia</a>. This mean the system is running +around 10 year old code, with no security fixes from the vendor for +many years.</p> + +<p>This is not the first time I discover the Oslo subway company, +Ruter, running outdated software.
