  24       <div class="date"> 1st May 2015</div>
  25       <div class="body"><p>Many years ago, a friend of mine calculated how much it would cost
  26 to store the sound of all phone calls in Norway, and came up with the
  27 cost of around 20 million NOK for all the calls in a year.  I got
  28 curious and wondered what the same calculation would look like today.
  29 To do so one need an idea of how much data storage is needed for each
  30 minute of sound, how many minutes all the calls in Norway sums up to,
  31 and the cost of data storage.</p>
  32
  33 <p>The 2005 numbers are from
  34 <a href="http://www.digi.no/analyser/2005/10/04/vi-prater-stadig-mindre-i-roret">digi.no</a>,
  35 the 2012 numbers are from
  36 <a href="http://www.nkom.no/aktuelt/nyheter/fortsatt-vekst-i-det-norske-ekommarkedet">a
  37 NKOM report</a>, and I got the 2013 numbers after asking NKOM via
  38 email.  I was told the numbers for 2014 will be presented May 20th,
  39 and decided not to wait for those, as I doubt they will be very
  40 different from the numbers from 2013.</p>
  41
  42 <p>The amount of data storage per minute sound depend on the wanted
  43 quality, and for phone calls it is generally believed that 8 Kbit/s is
  44 enough.  See for example a
  45 <a href="http://www.cisco.com/c/en/us/support/docs/voice/voice-quality/7934-bwidth-consume.html#topic1">summary
  46 on voice quality from Cisco</a> for some alternatives.  8 Kbit/s is 60
  47 Kbytes/min, and this can be multiplied with the number of call minutes
  48 to get the storage requirements.</p>
  49
  50 <p>Storage prices varies a lot, depending on speed, backup strategies,
  51 availability requirements etc.  But a simple way to calculate can be
  52 to use the price of a TiB-disk (around 1000 NOK) and double it to take
  53 space, power and redundancy.  It could be much higher with high speed
  54 and good redundancy requirements.</p>
  55
  56 <p>But back to the question, What would it cost to store all phone
  57 calls in Norway?  Not much.  Here is a small table showing the
  58 estimated cost, which is within the budget constraint of most medium
  59 and large organisations:</p>
  60
  61 <table border="1">
  62 <tr><th>Year</th><th>Call minutes</th><th>Size</th><th>Price in NOK</th></tr>
  63 <tr><td>2005</td><td align="right">24 000 000 000</td><td align="right">1.3 PiB</td><td align="right">3 mill</td></tr>
  64 <tr><td>2012</td><td align="right">18 000 000 000</td><td align="right">1.0 PiB</td><td align="right">2.2 mill</td></tr>
  65 <tr><td>2013</td><td align="right">17 000 000 000</td><td align="right">950 TiB</td><td align="right">2.1 mill</td></tr>
  66 </table>
  67
  68 <p>This is the cost of buying the storage.  Maintenance need to be
  69 taken into account too, but calculating that is left as an exercise
  70 for the reader.  But it is obvious to me from those numbers that
  71 recording the sound of all phone calls in Norway is not going to be
  72 stopped because it is too expensive.  I wonder if someone already are
  73 collecting the data?</p>

  88       <div class="body"><p>I am happy to report that the Debian Edu team sent out
  89 <a href="https://lists.debian.org/debian-edu-announce/2015/04/msg00000.html">this
  90 announcement today</a>:</p>
  91
  92 <pre>
  93 the Debian Edu / Skolelinux project is pleased to announce the first
  94 *beta* release of Debian Edu "Jessie" 8.0+edu0~b1, which for the first
  95 time is composed entirely of packages from the current Debian stable
  96 release, Debian 8 "Jessie".
  97
  98 (As most reading this will know, Debian "Jessie" hasn't actually been
  99 released by now. The release is still in progress but should finish
 100 later today ;)
 101
 102 We expect to make a final release of Debian Edu "Jessie" in the coming
 103 weeks, timed with the first point release of Debian Jessie. Upgrades
 104 from this beta release of Debian Edu Jessie to the final release will
 105 be possible and encouraged!
 106
 107 Please report feedback to debian-edu@lists.debian.org and/or submit
 108 bugs: http://wiki.debian.org/DebianEdu/HowTo/ReportBugs
 109
 110 Debian Edu - sometimes also known as "Skolelinux" - is a complete
 111 operating system for schools, universities and other
 112 organisations. Through its pre- prepared installation profiles
 113 administrators can install servers, workstations and laptops which
 114 will work in harmony on the school network.  With Debian Edu, the
 115 teachers themselves or their technical support staff can roll out a
 116 complete multi-user, multi-machine study environment within hours or
 117 days.
 118
 119 Debian Edu is already in use at several hundred schools all over the
 120 world, particularly in Germany, Spain and Norway. Installations come
 121 with hundreds of applications pre-installed, plus the whole Debian
 122 archive of thousands of compatible packages within easy reach.
 123
 124 For those who want to give Debian Edu Jessie a try, download and
 125 installation instructions are available, including detailed
 126 instructions in the manual explaining the first steps, such as setting
 127 up a network or adding users.  Please note that the password for the
 128 user your prompted for during installation must have a length of at
 129 least 5 characters!

 170 == Errata / known problems ==
 171
 172     It takes up to 15 minutes for a changed hostname to be updated via
 173     DHCP (#780461).
 174
 175     The hostname script fails to update LTSP server hostname (#783087).
 176
 177 Workaround: run update-hostname-from-ip on the client to update the
 178 hostname immediately.

 237 == About Debian Edu / Skolelinux ==
 238
 239 Debian Edu, also known as Skolelinux, is a Linux distribution based on
 240 Debian providing an out-of-the box environment of a completely
 241 configured school network. Directly after installation a school server
 242 running all services needed for a school network is set up just
 243 waiting for users and machines being added via GOsa², a comfortable
 244 Web-UI. A netbooting environment is prepared using PXE, so after
 245 initial installation of the main server from CD or USB stick all other
 246 machines can be installed via the network. The provided school server
 247 provides LDAP database and Kerberos authentication service,
 248 centralized home directories, DHCP server, web proxy and many other
 249 services.  The desktop contains more than 60 educational software
 250 packages and more are available from the Debian archive, and schools
 251 can choose between KDE, GNOME, LXDE, Xfce and MATE desktop
 252 environment.
 253
 254 == About Debian ==
 255
 256 The Debian Project was founded in 1993 by Ian Murdock to be a truly
 257 free community project. Since then the project has grown to be one of
 258 the largest and most influential open source projects. Thousands of
 259 volunteers from all over the world work together to create and
 260 maintain Debian software. Available in 70 languages, and supporting a
 261 huge range of computer types, Debian calls itself the universal
 262 operating system.
 263
 264 == Thanks ==
 265
 266 Thanks to everyone making Debian and Debian Edu / Skolelinux happen!
 267 You rock.

 282       <div class="date">15th April 2015</div>
 283       <div class="body"><p>It was a surprise to me to learn that project to create a complete
 284 computer system for schools I've involved in,
 285 <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>, was
 286 being used in India.  But apparently it is, and I managed to get an
 287 interview with one of the friends of the project there, Shirish
 288 Agarwal.</p>
 289
 290 <p><strong>Who are you, and how do you spend your days?</strong></p>
 291
 292 <p>My name is Shirish Agarwal. Based out of the educational and
 293 historical city of Pune, from the western state of Maharashtra, India.
 294 My bread comes from giving training, giving policy tips,
 295 installations on free software to mom and pop shops in different
 296 fields from Desktop publishing to retail shops as well as work with
 297 few software start-ups as well.</p>
 298
 299 <p><strong>How did you get in contact with the Skolelinux / Debian Edu
 300 project?</strong></p>
 301
 302 <p>It started innocently enough. I have been using Debian for a few
 303 years and in one local minidebconf / debutsav I was asked if there was
 304 anything for schools or education. I had worked / played with free
 305 educational softwares such as Gcompris and Stellarium for my many
 306 nieces and nephews so researched and found Debian Edu or Skolelinux as
 307 it was known then.  Since then I have started using the various
 308 education meta-packages provided by the project.</p>
 309
 310 <p><strong>What do you see as the advantages of Skolelinux / Debian
 311 Edu?</strong></p>
 312
 313 <p>It's closest I have seen where a package full of educational
 314 software are packed, which are free and open (both literally and
 315 figuratively).  Even if I take the simplest software which is
 316 gcompris, the number of activities therein are amazing. Another one of
 317 the softwares that I have liked for a long time is stellarium. Even
 318 pysycache is cool except for couple of issues I encountered
 319 <a href="https://bugs.debian.org/781841">#781841</a> and
 320 <a href="https://bugs.debian.org/781842">#781842</a>.</p>
 321
 322 <p>I prefer software installed on the system over web based solutions,
 323 as a web site can disappear any time but the software on disk has the
 324 possibility of a larger life span.  Of course with both it's more a
 325 question if it has enough users who make it fun or sustainable or both
 326 for the developer per-se.</p>
 327
 328 <p><strong>What do you see as the disadvantages of Skolelinux / Debian
 329 Edu?</strong></p>
 330
 331 <p>I do see that the Debian Edu team seems to be short-handed and I
 332 think more efforts should be made to make it popular and ask and take
 333 help from people and the larger community wherever possible.</p>
 334
 335 <p>I don't see any disadvantage to use Skolelinux apart from the fact
 336 that most apps. are generic which is good or bad how you see it.
 337 However, saying that I do acknowledge the fact that the canvas is
 338 pretty big and there are lot of interesting ideas that could be done
 339 but for reasons not known not done or if done I don't know about them.
 340 Let me share some of the ideas (these are more upstream based but
 341 still) I have had for a long time :</p>
 342
 343 <p>1. Classical maths question of two trains in opposing directions
 344 each running @x kmph/mph at y distance, when they will meet and how
 345 far would each travel and similar questions like these.
 346
 347 <p>The computer is a fantastic system where questions like these can
 348 be drawn, animated and the methodology and answers teased out in
 349 interactive manner. While sites such as the
 350 <a href="http://mathforum.org/dr.math/faq/faq.two.trains.html">Ask
 351 Dr. Math FAQ on The Two Trains problem</a> (as an example or point of
 352 inspiration) can be used there is lot more that can be done.  I dunno
 353 if there is a free software which does something like this.  The idea
 354 being a blend of objects + animation + interaction which does
 355 this. The whole interaction could be gamified with points or sounds or
 356 colourful celebration whenever the user gets even part of the question
 357 or/and methodology right. That would help reinforce good behaviour.
 358 This understanding could be used to share/showcase everything from how
 359 the first wheel came to be, to evolution to how astronomy started,
 360 psychics and everything in-between.</p>
 361
 362 <p>One specific idea in the train part was having the Linux mascot on
 363 one train and the BSD or GNU mascot on the other train and they
 364 meeting somewhere in-between. Characters from blender movies could
 365 also be used.</p>
 366
 367 <p>2. Loads of crossword-puzzles with reference to subjects: We have
 368 enormous data sets in Wikipedia and Wikitionary.  I don't think it
 369 should be a big job to design crossword puzzles. Using categories and
 370 sub-categories it should be doable to have Q&A single word answers
 371 from the existing data-sets. What would make it easy or hard could be
 372 the length of the word + existence of many or few vowels depending on
 373 the user's input.</p>
 374
 375 <p>3. Jigsaw puzzles - We already have a great software called
 376 palapeli with number of slicers making it pretty interesting. What
 377 needs to be done is to download large number of public domain and
 378 copyleft images, tease and use IPTC tags to categorise them into
 379 nature, history etc.  and let it loose. This could turn to be really
 380 huge collection of images. One source could be taken from
 381 commons.wikimedia.org, others could be huge collection of royalty-free
 382 stock photos. Potential is immense.</p>
 383
 384 <p>Apart from this, free software suffers in two directions, we lag
 385 both in development (of using new features per-se) and maintenance a
 386 lot.  This is more so in educational software as these applications
 387 need to be timely and the opportunity cost of missing deadlines is
 388 immense. If we are able to solve issues of funding for development and
 389 maintenance of such software I don't see any big difficulties. I know
 390 of few start-ups in and around India who would love to develop and
 391 maintain such software if funding issues could be solved.</p>
 392
 393 <p><strong>Which free software do you use daily?</strong></p>
 394
 395 <p>That would be huge list. Some of the softwares are obviously apt,
 396 aptitude, debdelta, leafpad, the shell of course (zsh nowadays),
 397 quassel for IRC. In games I use shisen-sho while card-games are evenly
 398 between kpat and Aiselriot.  In desktops it's a tie between
 399 gnome-flashback and mate.</p>
 400
 401 <p><strong>Which strategy do you believe is the right one to use to
 402 get schools to use free software?</strong></p>
 403
 404 <p>I think it should first start with using specific FOSS apps. in
 405 whatever environment they are. If it's MS-Windows or Mac so be it.
 406 Once they are habitual with the apps. and there is buy-in from the
 407 school management then it could be installed anywhere. Most of the
 408 people now understand the concept of a repository because of the
 409 various online stores so it isn't hard to convince on that front.</p>
 410
 411 <p>What is harder is having enough people with technical skills and
 412 passion to service them. If you get buy-in from one or two teachers
 413 then ideas like above could also be asked to be done as a project as
 414 well.</p>
 415
 416 <p>I think where we fall short more than anything is in marketing. For
 417 instance, Debian has this whole range of fonts in its archive but
 418 there isn't even a page where all those different fonts in the La
 419 Ipsum format could be tried out for newcomers.</p>
 420
 421 <p>One of the issues faced constantly in installations is with updates
 422 and upgrades.  People have this myth that each update and upgrade
 423 means the user interface will / has to change. I have seen this
 424 innumerable times.  That perhaps is one of the reasons which browsers
 425 like Iceweasel / Firefox change user interfaces so much, not because
 426 it might be needed or be functional but because people believe that
 427 changed user interfaces are better. This, can easily be pointed with
 428 the user interfaces changed with almost every MS-Windows and Mac OS
 429 releases.</p>
 430
 431 <p>The problems with Debian Edu for deployment are many. The biggest
 432 is the huge gap between what is taught in schools and what Debian Edu
 433 is aimed at.
 434
 435 <p>Me and my friends did teach on week-ends in a government school for
 436 around 2 years, and
 437 <a href="https://flossexperiences.wordpress.com/2012/10/08/sharings/">gathered
 438 some experience</a> there.  Some of the things we learnt/discovered
 439 there was :</p>
 440
 441 <ol>
 442
 443   <li>Most of the teachers are very territorial about their subjects
 444    and they do not want you to teach anything out of the
 445    portion/syllabus given.</li>
 446
 447   <li>They want any activity on the system in accordance to whatever
 448    is in the syllabus.</li>

 450   <li>There are huge barriers both with the English language and at
 451    times with objects or whatever. An example, let's say in gcompris
 452    you have objects falling down and you have to name them and let's
 453    say the falling object is a hat or a fedora hat, this would not be
 454    as recognizable as say a
 455    <a href="https://en.wikipedia.org/wiki/Puneri_Pagadi">Puneri
 456    Pagdi</a> so there is need to inject local objects, words wherever
 457    possible. Especially for word-games there are so many hindi words
 458    which have become part of english vocabulary (for instance in
 459    parley), those could be made into a hinglish collection or
 460    something but that is something for upstream to do.</li>

 542       <div class="body"><p>The <a href="http://www.nuug.no/">Norwegian Unix User Group</a>,
 543 where I am a member, and where people interested in free software,
 544 open standards and UNIX like operating systems like Linux and the BSDs
 545 come together, record our monthly technical presentations on video.
 546 The purpose is to document the talks and spread them to a wider
 547 audience.  For this, the the Norwegian nationwide open channel
 548 <a href="http://www.frikanalen.no/">Frikanalen</a> is a useful venue.
 549 Since a few days ago, when I figured out the
 550 <a href="http://beta.frikanalen.no/api/">REST API</a> to program the
 551 <a href="http://beta.frikanalen.tv/guide/">channel time schedule</a>,
 552 the channel has been filled with NUUG talks, related recordings and
 553 some Creative Commons licensed TED talks (from archive.org).  I fill
 554 all "leftover bits" on the channel with content from NUUG, which at
 555 the moment is almost 17 of 24 hours every day.</p>
 556
 557 <p>The list of NUUG videos
 558 <a href="http://beta.frikanalen.tv/organization/82">uploaded so far</a>
 559 include things like a
 560 <a href="http://beta.frikanalen.tv/video/625090">one hour talk by John
 561 Perry Barlow when he visited Oslo</a>, a presentation of
 562 <a href="http://beta.frikanalen.tv/video/624275">Haiku, the BeOS
 563 re-implementation</a>, the
 564 <a href="http://beta.frikanalen.tv/video/624493">history of FiksGataMi,
 565 the Norwegian version of FixMyStreet</a>, the good old
 566 <a href="http://beta.frikanalen.tv/video/623566">Warriors of the net
 567 video</A> and many others.</p>
 568
 569 <p>We have a large backlog of NUUG talks not yet uploaded to
 570 Frikanalen, and plan to upload every useful bit to the channel to
 571 spread the word there.  I also hope to find useful recordings from the
 572 Chaos Computer Club and Debian conferences and spread them on the
 573 channel as well.  But this require locating the videos and their meta
 574 information (title, description, license, etc), and preparing the
 575 recordings for broadcast, and I have not yet had the spare time to
 576 focus on this.  Perhaps you want to help.  Please join us on IRC,
 577 <a href="irc://irc.freenode.net/%23nuug">#nuug on irc.freenode.net</a>
 578 if you want to help make this happen.</p>
 579
 580 <p>But as I said, already the channel is already almost exclusively
 581 filled with technical topics, and if you want to learn something new
 582 today, check out the <a href="http://www.frikanalen.tv/se">Ogg Theora
 583 web stream</a> or use one of the other ways to get access to the
 584 channel.  Unfortunately the Ogg Theora recoding for distribution still
 585 do not properly sync the video and sound.  It is generated by recoding
 586 a internal MPEG transport stream with MPEG4 coded video (ie H.264) to
 587 Ogg Theora / Vorbis, and we have not been able to find a way that
 588 produces acceptable quality.  Help needed, please get in touch if you
 589 know how to fix it using free software.</p>

 641       <div class="body"><p>The Norwegian nationwide open channel
 642 <a href="http://www.frikanalen.no/">Frikanalen</a> is still going
 643 strong.  It allow everyone to send the video they want on national
 644 television.  It is a TV station administrated completely using a web
 645 browser, running only <ahref="https://github.com/Frikanalen">Free
 646 Software</a>, providing <ahref="http://beta.frikanalen.tv/api">a REST
 647 api</a> for administrators and members, and with distribution on the
 648 national DVB-T distribution network RiksTV.  But only between 12:00
 649 and 17:30 Norwegian time.  This has finally changed, after many years
 650 with limited distribution.  A few weeks ago, we set up a Ogg Theora
 651 stream via icecast to allow everyone with Internet access to check out
 652 the channel the rest of the day.  This is presented on
 653 <a href="http://www.frikanalen.tv/se">the Frikanalen web site now</a>.  And
 654 since a few days ago, the channel is also available
 655 via <a href="https://www.uninett.no/iptv-tilgang">multicast on
 656 UNINETT</a>, available for those using IPTV TVs and set-top boxes in
 657 the Norwegian National Research and Education network.</p>
 658
 659 <p>If you want to see what is on the channel, point your media player
 660 to one of these sources.  The first should work with most players and
 661 browsers, while as far as I know, the multicast UDP stream only work
 662 with VLC.</p>

 667 </ul>
 668
 669 <p>The Ogg Theora / icecast stream is not working well, as the video
 670 and audio is slightly out of sync.  We have not been able to figure
 671 out how to fix it.  It is generated by recoding a internal MPEG
 672 transport stream with MPEG4 coded video (ie H.264) to Ogg Theora /
 673 Vorbis, and the result is less then stellar.  If you have ideas how to
 674 fix it, please let us know on frikanalen (at) nuug.no.  We currently
 675 use this with ffmpeg2theora 0.29:</p>
 676
 677 <blockquote><pre>
 678 ./ffmpeg2theora.linux &lt;OBE_gemini_URL.ts&gt; -F 25 -x 720 -y 405 \

 681 </pre></blockquote>
 682
 683 <p>If you get the multicast UDP stream working, please let me know, as
 684 I am curious how far the multicast stream reach.  It do not make it to
 685 my home network, nor any other commercially available network in
 686 Norway that I am aware of.</p>

 700       <div class="date">12th February 2015</div>
 701       <div class="body"><p>En stund nå har jeg vært nødt til å forholde meg til
 702 <a href="https://fronter.com/osloskoler/">Fronter</a>, en nettløsning
 703 Osloskolen bruker for kontakt mellom hjem og skole.  Løsningen
 704 imponerer ikke, og det er lagt opp til at vi foreldre skal logge inn
 705 regelmessig for å se om noe har endret seg.  Idéen om å la folk stikke
 706 innom nettsider for å se om det har skjedd endringer er så idiotisk at
 707 jeg har lett etter et alternativ.  Fronterløsningen har en innebygget
 708 løsning der en kan abonnere på forsiden (som viser en oppsummering av
 709 det en har tilgang til), og få tilsendt en kopi hver natt, men det
 710 fjerner jo bare behovet for å stikke innom, ikke den idiotiske ideen
 711 om at folk skal huske hvordan nettsiden så ut sist og oppdage hva som
 712 er endret.</p>
 713
 714 <p>For å gjøre livet enklere har jeg derfor brukt litt tid på å lage
 715 et program som kobler seg opp og sjekker etter endringer automatisk,
 716 slik at jeg kan få beskjed fra datamaskinen når noe endrer seg i
 717 stedet for å forsøke å finne ut av det selv.  I går ble scriptet
 718 brukbart, og jeg er dermed klar til å dele det med deg.</p>
 719
 720 <p>Jeg startet med å skrive programmet i Python, og hadde en versjon
 721 som logget inn og hentet ned enkeltsider fra Fronter.  Men
 722 Fronter-websidene suger golfballer gjennom en hageslange, med
 723 uleselig HTML, flere nivåer av iframes og en struktur på innholdet som
 724 er svært vanskelig å finne ut av, så jeg ga til slutt opp lxml-parsing
 725 med Python og forsøkte meg med WWW::Mechanize for Perl som jeg kjente
 726 fra før.  I ettertid har jeg oppdaget at WWW:Mechanize også finnes for
 727 Python, så jeg kunne antagelig droppet språkbyttet.  Men da jeg
 728 oppdaget det hadde jeg kommet så langt med Perl-utgaven, så jeg hoppet
 729 ikke tilbake.</p>
 730
 731 <p>For å logge inn i Fronter besøker en enten skolens websider eller
 732 den sentrale innloggingsiden <tt>https://fronter.com/osloskoler/</tt>.
 733 Perl-koden for å logge inn ser slik ut:</p>
 734
 735 <pre>
 736 my $mech = WWW::Mechanize->new();
 737 $mech->get('https://fronter.com/osloskoler/');
 738 $mech->submit_form(fields => {
 739     username => $username,
 740     password => $password,
 741 } );
 742 </pre>
 743
 744 <p>Neste steg er å få oversikt over hvilke «rom» en har tilgang til.
 745 På vår skole er det rom for skolen, biblioteket, elevrådet,
 746 aktivitetsskolen og klasser der en har unger, og dette vil være
 747 forskjellig fra person til person.  Etter å ha romstert rundt i
 748 Fronter-grensesnittet endel kom jeg over en grei HTML-side med
 749 oversikt over rommene,
 750 <tt>https://fronter.com/osloskoler/adm/projects.phtml?mode=displayRoomchooser</tt>,
 751 så jeg bruker denne til å hente ut romoversikt med rom-ID.</p>
 752
 753 <pre>
 754 my %room;
 755 $mech->get('https://fronter.com/osloskoler/adm/projects.phtml?mode=displayRoomchooser');
 756 for my $link ($mech->links()) {
 757     my $url = $link->url();
 758     if ($url =~ m%/links/list_files.phtml\?edit=(\d+)$%) {
 759         $room{$link->text()} = $1;
 760     }
 761 }
 762 </pre>
 763
 764 <p>Når en har rom-ID kan en slå opp websiden for rommet, som starter
 765 på
 766 <tt>https://fronter.com/osloskoler/contentframeset.phtml?goto_prjid=$ROMID</tt>
 767 (der $ROMID byttes ut med rom-ID-tallet).  Det gir en side med
 768 iframes, og en må tre nivåer ned i iframes før en får tak i
 769 HTML-informasjonen som vises frem når en ser på det aktuelle rommet.
 770 Her ga jeg opp den robuste parsingen og hardkodet endel URL-er som i
 771 stedet bør spores opp maskinelt.  HTML-informasjonen som vises lagres
 772 i en fil etter at økt- og innloggings-nøkkel er fjernet og deretter
 773 bruker jeg <tt>lynx --dump --nolist</tt> for å hente ut en tekstlig
 774 utgave av websiden.  Denne tekstlige utgaven sammenlignes med forrige
 775 versjon og oversikt over endringer kan så sendes ut på egnet vis.</p>
 776
 777 <p>Jeg valgte å bruke git til å holde rede på endringer, så jeg
 778 sjekker inn HTML og tekst-utgaver i git og bruker git til å vise frem
 779 endringene i tekstutgavene.  Programvaren for å gjøre dette er testet
 780 på Debian GNU/Linux og kan
 781 <a href="https://github.com/petterreinholdtsen/fronter-scraper-oslo">lastes
 782 ned fra github</a>.</p>
 783
 784 <p>For å bruke dette selv, kjør følgende kommandoer på din
 785 Debian-maskin (forutsetter sudo-tilgang for installasjon av
 786 programvare):</p>
 787
 788 <pre>
 789 sudo apt-get install git lynx-cur libio-prompter-perl libwww-mechanize-perl \
 790       libconfig-inifiles-perl
 791 git clone https://github.com/petterreinholdtsen/fronter-scraper-oslo
 792 cd fronter-scraper-oslo
 793 ./update-git
 794 </pre>
 795
 796 <p>Det gjenstår endel, men systemet er allerede nyttig for meg.  Jeg
 797 ønsker at systemet også skal laste ned PDF-er og slikt som er lagt ut
 798 for nedlasting på sidene, slik at f.eks. ukeplaner kommer inn i
 799 git-arkivet mitt automatisk og jeg får automatisk beskjed når ny
 800 ukeplan er lagt ut.  Kanskje du kan bidra med å få det på plass, eller
 801 kanskje du har andre ting du vil fikse?  Jeg tar gjerne imot endringer
 802 og forbedringer.  Det er mye som kan gjøres bedre, og scriptet er ikke
 803 veldig robust mot endringer hos nettsidene til Fronter.  Jeg regner
 804 dermed med at det vil trengs oppdateringer jevnlig etter hvert som
 805 Fronter-løsningen endrer seg.</p>

 819       <div class="date">10th February 2015</div>
 820       <div class="body"><p>Aftenposten, one of the largest newspapers in Norway, today report
 821 that
 822 <a href="http://www.aftenposten.no/reise/Slik-skannes-kroppen-din-i-fremtidens-sikkerhetskontroll-490666_1.snd">three
 823 of the nude body scanners now is put to use at Gardermoen</a>, the
 824 main airport in Norway.  This way the travelers can have their body
 825 photographed without cloths when visiting Norway.  Of course this
 826 horrible news is presented with a positive spin, stating that "now
 827 travelers can move past the security check point faster and more
 828 efficiently", but fail to mention that the machines in question take
 829 pictures of their nude bodies and store them internally in the
 830 computer, while only presenting sketch figure of the body to the
 831 public.  The article is written in a way that leave the impression
 832 that the new machines do not take these nude pictures and only create
 833 the sketch figures.  In reality the same nude pictures are still
 834 taken, but not presented to everyone.  They are still available for
 835 the owners of the system and the people doing maintenance of the
 836 scanners, as long as they are taken and stored.</p>
 837
 838 <p>Wikipedia have a more on
 839 <a href="https://en.wikipedia.org/wiki/Full_body_scanner">Full body
 840 scanners</a>, including example images and a summary of the
 841 controversy about these scanners.</p>
 842
 843 <p>Personally I will decline to use these machines, as I believe strip
 844 searches of my body is a very intrusive attack on my privacy, and not
 845 something everyone should have to accept to travel.</p>
