  25       <div class="body"><p>For mange år siden leste jeg en klassisk tekst som gjorde såpass
  26 inntrykk på meg at jeg husker den fortsatt, flere år senere, og bruker
  27 argumentene fra den stadig vekk.  Teksten var «The Relativity of
  28 Wrong» som Isaac Asimov publiserte i Skeptical Inquirer i 1989.  Den
  29 gir litt perspektiv rundt formidlingen av vitenskapelige resultater.
  30 Jeg har hatt lyst til å kunne dele den også med folk som ikke
  31 behersker Engelsk så godt, som barn og noen av mine eldre slektninger,
  32 og har savnet å ha den tilgjengelig på norsk.  For to uker siden tok
  33 jeg meg sammen og kontaktet Asbjørn Dyrendal i foreningen Skepsis om
  34 de var interessert i å publisere en norsk utgave på bloggen sin, og da
  35 han var positiv tok jeg kontakt med Skeptical Inquirer og spurte om
  36 det var greit for dem.  I løpet av noen dager fikk vi tilbakemelding
  37 fra Barry Karr hos The Skeptical Inquirer som hadde sjekket og fått OK
  38 fra Robyn Asimov som representerte arvingene i Asmiov-familien og gikk
  39 igang med oversettingen.</p>
  40
  41 <p>Resultatet, <a href="http://www.skepsis.no/?p=1617">«Relativt
  42 feil»</a> ble publisert på skepsis-bloggen for noen minutter siden.
  43 Jeg anbefaler deg på det varmeste å lese denne teksten og dele den med
  44 dine venner.</p>
  45
  46 <p>For å håndtere oversettelsen og sikre at original og oversettelse
  47 var i sync brukte vi git, po4a, GNU make og Transifex.  Det hele
  48 fungerte utmerket og gjorde det enkelt å dele tekstene og jobbe sammen
  49 om finpuss på formuleringene.  Hadde hosted.weblate.org latt meg
  50 opprette nye prosjekter selv i stedet for å måtte kontakte
  51 administratoren der, så hadde jeg brukt weblate i stedet.</p>

  68 broadcasting talks by or about
  69 <a href="http://beta.frikanalen.no/video/625529/">Linus Torvalds</a>,

  77 using only free software (all of it
  78 <a href="http://github.com/Frikanalen">available from Github</a>), and
  79 is administrated using a web browser and a web API.</p>
  80
  81 <p>The TV channel is the Norwegian open channel
  82 <a href="http://www.frikanalen.no/">Frikanalen</a>, and I am involved
  83 via <a href="https://www.nuug.no/">the NUUG member association</a> in
  84 running and developing the software for the channel.  The channel is
  85 organised as a member organisation where its members can upload and
  86 broadcast what they want (think of it as Youtube for national
  87 broadcasting television).  Individuals can broadcast too.  The time
  88 slots are handled on a first come, first serve basis.  Because the
  89 channel have almost no viewers and very few active members, we can
  90 experiment with TV technology without too much flack when we make
  91 mistakes.  And thanks to the few active members, most of the slots on
  92 the schedule are free.  I see this as an opportunity to spread
  93 knowledge about technology and free software, and have a script I run
  94 regularly to fill up all the open slots the next few days with
  95 technology related video.  The end result is a channel I like to
  96 describe as Techno TV - filled with interesting talks and
  97 presentations.</p>
  98
  99 <p>It is available on channel 50 on the Norwegian national digital TV
 100 network (RiksTV).  It is also available as a multicast stream on
 101 Uninett.  And finally, it is available as
 102 <a href="http://beta.frikanalen.no/">a WebM unicast stream</a> from
 103 Frikanalen and NUUG.  Check it out. :)</p>

 117       <div class="date"> 7th July 2016</div>
 118       <div class="body"><p>Yesterday, I tried to unlock a HTC Desire HD phone, and it proved
 119 to be a slight challenge.  Here is the recipe if I ever need to do it
 120 again.  It all started by me wanting to try the recipe to set up
 121 <a href="https://blog.torproject.org/blog/mission-impossible-hardening-android-security-and-privacy">an
 122 hardened Android installation</a> from the Tor project blog on a
 123 device I had access to.  It is a old mobile phone with a broken
 124 microphone The initial idea had been to just
 125 <a href="http://wiki.cyanogenmod.org/w/Install_CM_for_ace">install
 126 CyanogenMod on it</a>, but did not quite find time to start on it
 127 until a few days ago.</p>
 128
 129 <p>The unlock process is supposed to be simple: (1) Boot into the boot
 130 loader (press volume down and power at the same time), (2) select
 131 'fastboot' before (3) connecting the device via USB to a Linux
 132 machine, (4) request the device identifier token by running 'fastboot
 133 oem get_identifier_token', (5) request the device unlocking key using
 134 the <a href="http://www.htcdev.com/bootloader/">HTC developer web
 135 site</a> and unlock the phone using the key file emailed to you.</p>
 136
 137 <p>Unfortunately, this only work fi you have hboot version 2.00.0029
 138 or newer, and the device I was working on had 2.00.0027.  This
 139 apparently can be easily fixed by downloading a Windows program and
 140 running it on your Windows machine, if you accept the terms Microsoft
 141 require you to accept to use Windows - which I do not.  So I had to
 142 come up with a different approach.  I got a lot of help from AndyCap
 143 on #nuug, and would not have been able to get this working without
 144 him.</p>
 145
 146 <p>First I needed to extract the hboot firmware from
 147 <a href="http://www.htcdev.com/ruu/PD9810000_Ace_Sense30_S_hboot_2.00.0029.exe">the
 148 windows binary for HTC Desire HD</a> downloaded as 'the RUU' from HTC.
 149 For this there is is <a href="https://github.com/kmdm/unruu/">a github
 150 project named unruu</a> using libunshield.  The unshield tool did not
 151 recognise the file format, but unruu worked and extracted rom.zip,
 152 containing the new hboot firmware and a text file describing which
 153 devices it would work for.</p>
 154
 155 <p>Next, I needed to get the new firmware into the device.  For this I
 156 followed some instructions
 157 <a href="http://www.htc1guru.com/2013/09/new-ruu-zips-posted/">available
 158 from HTC1Guru.com</a>, and ran these commands as root on a Linux
 159 machine with Debian testing:</p>
 160
 161 <p><pre>
 162 adb reboot-bootloader
 163 fastboot oem rebootRUU
 164 fastboot flash zip rom.zip
 165 fastboot flash zip rom.zip
 166 fastboot reboot
 167 </pre></p>
 168
 169 <p>The flash command apparently need to be done twice to take effect,
 170 as the first is just preparations and the second one do the flashing.
 171 The adb command is just to get to the boot loader menu, so turning the
 172 device on while holding volume down and the power button should work
 173 too.</p>
 174
 175 <p>With the new hboot version in place I could start following the
 176 instructions on the HTC developer web site.  I got the device token
 177 like this:</p>
 178
 179 <p><pre>
 180 fastboot oem get_identifier_token 2>&1 | sed 's/(bootloader) //'
 181 </pre>
 182
 183 <p>And once I got the unlock code via email, I could use it like
 184 this:</p>
 185
 186 <p><pre>
 187 fastboot flash unlocktoken Unlock_code.bin
 188 </pre></p>
 189
 190 <p>And with that final step in place, the phone was unlocked and I
 191 could start stuffing the software of my own choosing into the device.
 192 So far I only inserted a replacement recovery image to wipe the phone
 193 before I start.  We will see what happen next.  Perhaps I should
 194 install <a href="https://www.debian.org/">Debian</a> on it. :)</p>

 208       <div class="date"> 3rd July 2016</div>
 209       <div class="body"><p>For a while now, I have wanted to test
 210 <a href="https://whispersystems.org/">the Signal app</a>, as it is
 211 said to provide end to end encrypted communication and several of my
 212 friends and family are already using it.  As I by choice do not own a
 213 mobile phone, this proved to be harder than expected.  And I wanted to
 214 have the source of the client and know that it was the code used on my
 215 machine.  But yesterday I managed to get it working.  I used the
 216 Github source, compared it to the source in
 217 <a href="https://chrome.google.com/webstore/detail/signal-private-messenger/bikioccmkafdpakkkcpdbppfkghcmihk?hl=en-US">the
 218 Signal Chrome app</a> available from the Chrome web store, applied
 219 patches to use the production Signal servers, started the app and
 220 asked for the hidden "register without a smart phone" form.  Here is
 221 the recipe how I did it.</p>
 222
 223 <p>First, I fetched the Signal desktop source from Github, using
 224
 225 <pre>
 226 git clone https://github.com/WhisperSystems/Signal-Desktop.git
 227 </pre>
 228
 229 <p>Next, I patched the source to use the production servers, to be
 230 able to talk to other Signal users:</p>

 261
 262 <p>The first part is changing the servers, and the second is updating
 263 an expiration timestamp.  This timestamp need to be updated regularly.
 264 It is set 90 days in the future by the build process (Gruntfile.js).
 265 The value is seconds since 1970 times 1000, as far as I can tell.</p>
 266
 267 <p>Based on a tip and good help from the #nuug IRC channel, I wrote a
 268 script to launch Signal in Chromium.</p>
 269
 270 <pre>
 271 #!/bin/sh
 272 cd $(dirname $0)
 273 mkdir -p userdata
 274 exec chromium \
 275   --proxy-server="socks://localhost:9050" \
 276   --user-data-dir=`pwd`/userdata --load-and-launch-app=`pwd`
 277 </pre>
 278
 279 <p> The script start the app and configure Chromium to use the Tor
 280 SOCKS5 proxy to make sure those controlling the Signal servers (today
 281 Amazon and Whisper Systems) as well as those listening on the lines
 282 will have a harder time location my laptop based on the Signal
 283 connections if they use source IP address.</p>
 284
 285 <p>When the script starts, one need to follow the instructions under
 286 "Standalone Registration" in the CONTRIBUTING.md file in the git
 287 repository.  I right clicked on the Signal window to get up the
 288 Chromium debugging tool, visited the 'Console' tab and wrote
 289 'extension.install("standalone")' on the console prompt to get the
 290 registration form.  Then I entered by land line phone number and
 291 pressed 'Call'.  5 seconds later the phone rang and a robot voice
 292 repeated the verification code three times.  After entering the number
 293 into the verification code field in the form, I could start using
 294 Signal from my laptop.
 295
 296 <p>As far as I can tell, The Signal app will leak who is talking to
 297 whom and thus who know who to those controlling the central server,
 298 but such leakage is hard to avoid with a centrally controlled server
 299 setup.  It is something to keep in mind when using Signal - the
 300 content of your chats are harder to intercept, but the meta data
 301 exposing your contact network is available to people you do not know.
 302 So better than many options, but not great.  And sadly the usage is
 303 connected to my land line, thus allowing those controlling the server
 304 to associate it to my home and person.  I would prefer it if only
 305 those I knew could tell who I was on Signal.  There are options
 306 avoiding such information leakage, but most of my friends are not
 307 using them, so I am stuck with Signal for now.</p>

 321       <div class="date"> 6th June 2016</div>
 322       <div class="body"><p>When I set out a few weeks ago to figure out
 323 <a href="http://people.skolelinux.org/pere/blog/What_is_the_best_multimedia_player_in_Debian_.html">which
 324 multimedia player in Debian claimed to support most file formats /
 325 MIME types</a>, I was a bit surprised how varied the sets of MIME types
 326 the various players claimed support for.  The range was from 55 to 130
 327 MIME types.  I suspect most media formats are supported by all
 328 players, but this is not really reflected in the MimeTypes values in
 329 their desktop files.  There are probably also some bogus MIME types
 330 listed, but it is hard to identify which one this is.</p>
 331
 332 <p>Anyway, in the mean time I got in touch with upstream for some of
 333 the players suggesting to add more MIME types to their desktop files,
 334 and decided to spend some time myself improving the situation for my
 335 favorite media player VLC.  The fixes for VLC entered Debian unstable
 336 yesterday. The complete list of MIME types can be seen on the
 337 <a href="https://wiki.debian.org/DebianMultimedia/PlayerSupport">Multimedia
 338 player MIME type support status</a> Debian wiki page.</p>
 339
 340 <p>The new "best" multimedia player in Debian?  It is VLC, followed by
 341 totem, parole, kplayer, gnome-mpv, mpv, smplayer, mplayer-gui and
 342 kmplayer.  I am sure some of the other players desktop files support
 343 several of the formats currently listed as working only with vlc,
 344 toten and parole.</p>
 345
 346 <p>A sad observation is that only 14 MIME types are listed as
 347 supported by all the tested multimedia players in Debian in their
 348 desktop files: audio/mpeg, audio/vnd.rn-realaudio, audio/x-mpegurl,
 349 audio/x-ms-wma, audio/x-scpls, audio/x-wav, video/mp4, video/mpeg,
 350 video/quicktime, video/vnd.rn-realvideo, video/x-matroska,
 351 video/x-ms-asf, video/x-ms-wmv and video/x-msvideo.  Personally I find
 352 it sad that video/ogg and video/webm is not supported by all the media
 353 players in Debian.  As far as I can tell, all of them can handle both
 354 formats.</p>

 370 decided to test its presentation tool when making the slides for a
 371 talk I was giving for NUUG on Japhar, a free Java virtual machine.  I
 372 wrote the first draft of the slides, saved the result and went to bed
 373 the day before I would give the talk.  The next day I took a plane to
 374 the location where the meeting should take place, and on the plane I
 375 started up koffice again to polish the talk a bit, only to discover
 376 that kpresenter refused to load its own data file.  I cursed a bit and
 377 started making the slides again from memory, to have something to
 378 present when I arrived.  I tested that the saved files could be
 379 loaded, and the day seemed to be rescued.  I continued to polish the
 380 slides until I suddenly discovered that the saved file could no longer
 381 be loaded into kpresenter.  In the end I had to rewrite the slides
 382 three times, condensing the content until the talk became shorter and
 383 shorter.  After the talk I was able to pinpoint the problem &ndash;
 384 kpresenter wrote inline images in a way itself could not understand.
 385 Eventually that bug was fixed and kpresenter ended up being a great
 386 program to make slides.  The point I'm trying to make is that we
 387 expect a program to be able to load its own data files, and it is
 388 embarrassing to its developers if it can't.</p>
 389
 390 <p>Did you ever experience a program failing to load its own data
 391 files from the desktop file browser?  It is not a uncommon problem.  A
 392 while back I discovered that the screencast recorder
 393 gtk-recordmydesktop would save an Ogg Theora video file the KDE file
 394 browser would refuse to open.  No video player claimed to understand
 395 such file.  I tracked down the cause being <tt>file --mime-type</tt>
 396 returning the application/ogg MIME type, which no video player I had
 397 installed listed as a MIME type they would understand.  I asked for
 398 <a href="http://bugs.gw.com/view.php?id=382">file to change its
 399 behavour</a> and use the MIME type video/ogg instead.  I also asked
 400 several video players to add video/ogg to their desktop files, to give
 401 the file browser an idea what to do about Ogg Theora files.  After a
 402 while, the desktop file browsers in Debian started to handle the
 403 output from gtk-recordmydesktop properly.</p>
 404
 405 <p>But history repeats itself.  A few days ago I tested the music
 406 system Rosegarden again, and I discovered that the KDE and xfce file
 407 browsers did not know what to do with the Rosegarden project files
 408 (*.rg).  I've reported <a href="http://bugs.debian.org/825993">the
 409 rosegarden problem to BTS</a> and a fix is commited to git and will be
 410 included in the next upload.  To increase the chance of me remembering
 411 how to fix the problem next time some program fail to load its files
 412 from the file browser, here are some notes on how to fix it.</p>
 413
 414 <p>The file browsers in Debian in general operates on MIME types.
 415 There are two sources for the MIME type of a given file.  The output from
 416 <tt>file --mime-type</tt> mentioned above, and the content of the
 417 shared MIME type registry (under /usr/share/mime/).  The file MIME
 418 type is mapped to programs supporting the MIME type, and this
 419 information is collected from
 420 <a href="https://www.freedesktop.org/wiki/Specifications/desktop-entry-spec/">the
 421 desktop files</a> available in /usr/share/applications/.  If there is
 422 one desktop file claiming support for the MIME type of the file, it is
 423 activated when asking to open a given file.  If there are more, one
 424 can normally select which one to use by right-clicking on the file and
 425 selecting the wanted one using 'Open with' or similar.  In general
 426 this work well.  But it depend on each program picking a good MIME
 427 type (preferably
 428 <a href="http://www.iana.org/assignments/media-types/media-types.xhtml">a
 429 MIME type registered with IANA</a>), file and/or the shared MIME
 430 registry recognizing the file and the desktop file to list the MIME
 431 type in its list of supported MIME types.</p>
 432
 433 <p>The <tt>/usr/share/mime/packages/rosegarden.xml</tt> entry for
 434 <a href="http://www.freedesktop.org/wiki/Specifications/shared-mime-info-spec">the
 435 Shared MIME database</a> look like this:</p>
 436
 437 <p><blockquote><pre>
 438 &lt;?xml version="1.0" encoding="UTF-8"?&gt;
 439 &lt;mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info"&gt;
 440   &lt;mime-type type="audio/x-rosegarden"&gt;
 441     &lt;sub-class-of type="application/x-gzip"/&gt;
 442     &lt;comment&gt;Rosegarden project file&lt;/comment&gt;
 443     &lt;glob pattern="*.rg"/&gt;
 444   &lt;/mime-type&gt;
 445 &lt;/mime-info&gt;
 446 </pre></blockquote></p>
 447
 448 <p>This states that audio/x-rosegarden is a kind of application/x-gzip
 449 (it is a gzipped XML file).  Note, it is much better to use an
 450 official MIME type registered with IANA than it is to make up ones own
 451 unofficial ones like the x-rosegarden type used by rosegarden.</p>
 452
 453 <p>The desktop file of the rosegarden program failed to list
 454 audio/x-rosegarden in its list of supported MIME types, causing the
 455 file browsers to have no idea what to do with *.rg files:</p>
 456
 457 <p><blockquote><pre>
 458 % grep Mime /usr/share/applications/rosegarden.desktop
 459 MimeType=audio/x-rosegarden-composition;audio/x-rosegarden-device;audio/x-rosegarden-project;audio/x-rosegarden-template;audio/midi;
 460 X-KDE-NativeMimeType=audio/x-rosegarden-composition
 461 %
 462 </pre></blockquote></p>
 463
 464 <p>The fix was to add "audio/x-rosegarden;" at the end of the
 465 MimeType= line.</p>
 466
 467 <p>If you run into a file which fail to open the correct program when
 468 selected from the file browser, please check out the output from
 469 <tt>file --mime-type</tt> for the file, ensure the file ending and
 470 MIME type is registered somewhere under /usr/share/mime/ and check
 471 that some desktop file under /usr/share/applications/ is claiming
 472 support for this MIME type.  If not, please report a bug to have it
 473 fixed. :)</p>

 487       <div class="date">28th May 2016</div>
 488       <div class="body"><p>A little more than 11 years ago, one of the creators of Tor, and
 489 the current President of <a href="https://www.torproject.org/">the Tor
 490 project</a>, Roger Dingledine, gave a talk for the members of the
 491 <a href="http://www.nuug.no/">Norwegian Unix User group</a> (NUUG).  A
 492 video of the talk was recorded, and today, thanks to the great help
 493 from David Noble, I finally was able to publish the video of the talk
 494 on Frikanalen, the Norwegian open channel TV station where NUUG
 495 currently publishes its talks.  You can
 496 <a href="http://frikanalen.no/se">watch the live stream using a web
 497 browser</a> with WebM support, or check out the recording on the video
 498 on demand page for the talk
 499 "<a href="http://beta.frikanalen.no/video/625599">Tor: Anonymous

 501
 502 <p>Here is the video included for those of you using browsers with
 503 HTML video and Ogg Theora support:</p>

 508
 509 <p>I guess the gist of the talk can be summarised quite simply: If you

 524       <div class="date">25th May 2016</div>
 525       <div class="body"><p><a href="https://tracker.debian.org/pkg/isenkram">The isenkram
 526 system</a> is a user-focused solution in Debian for handling hardware
 527 related packages.  The idea is to have a database of mappings between
 528 hardware and packages, and pop up a dialog suggesting for the user to
 529 install the packages to use a given hardware dongle.  Some use cases
 530 are when you insert a Yubikey, it proposes to install the software
 531 needed to control it; when you insert a braille reader list it
 532 proposes to install the packages needed to send text to the reader;
 533 and when you insert a ColorHug screen calibrator it suggests to
 534 install the driver for it.  The system work well, and even have a few
 535 command line tools to install firmware packages and packages for the
 536 hardware already in the machine (as opposed to hotpluggable hardware).</p>
 537
 538 <p>The system was initially written using aptdaemon, because I found
 539 good documentation and example code on how to use it.  But aptdaemon
 540 is going away and is generally being replaced by
 541 <a href="http://www.freedesktop.org/software/PackageKit/">PackageKit</a>,
 542 so Isenkram needed a rewrite.  And today, thanks to the great patch
 543 from my college Sunil Mohan Adapa in the FreedomBox project, the
 544 rewrite finally took place.  I've just uploaded a new version of
 545 Isenkram into Debian Unstable with the patch included, and the default
 546 for the background daemon is now to use PackageKit.  To check it out,
 547 install the <tt>isenkram</tt> package and insert some hardware dongle
 548 and see if it is recognised.</p>
 549
 550 <p>If you want to know what kind of packages isenkram would propose for
 551 the machine it is running on, you can check out the isenkram-lookup
 552 program.  This is what it look like on a Thinkpad X230:</p>
 553
 554 <p><blockquote><pre>
 555 % isenkram-lookup
 556 bluez
 557 cheese
 558 fprintd
 559 fprintd-demo
 560 gkrellm-thinkbat
 561 hdapsd
 562 libpam-fprintd
 563 pidgin-blinklight
 564 thinkfan
 565 tleds
 566 tp-smapi-dkms
 567 tp-smapi-source
 568 tpb
 569 %p
 570 </pre></blockquote></p>
 571
 572 <p>The hardware mappings come from several places.  The preferred way
 573 is for packages to announce their hardware support using
 574 <a href="https://www.freedesktop.org/software/appstream/docs/">the
 575 cross distribution appstream system</a>.
 576 See
 577 <a href="http://people.skolelinux.org/pere/blog/tags/isenkram/">previous
 578 blog posts about isenkram</a> to learn how to do that.</p>

 592       <div class="date">23rd May 2016</div>
 593       <div class="body"><p>Yesterday I updated the
 594 <a href="https://tracker.debian.org/pkg/battery-stats">battery-stats
 595 package in Debian</a> with a few patches sent to me by skilled and
 596 enterprising users.  There were some nice user and visible changes.
 597 First of all, both desktop menu entries now work.  A design flaw in
 598 one of the script made the history graph fail to show up (its PNG was
 599 dumped in ~/.xsession-errors) if no controlling TTY was available.
 600 The script worked when called from the command line, but not when
 601 called from the desktop menu.  I changed this to look for a DISPLAY
 602 variable or a TTY before deciding where to draw the graph, and now the
 603 graph window pop up as expected.</p>
 604
 605 <p>The next new feature is a discharge rate estimator in one of the
 606 graphs (the one showing the last few hours).  New is also the user of
 607 colours showing charging in blue and discharge in red.  The percentages
 608 of this graph is relative to last full charge, not battery design
 609 capacity.</p>
 610
 611 <p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2016-05-23-battery-stats-rate.png"/></p>
 612
 613 <p>The other graph show the entire history of the collected battery
 614 statistics, comparing it to the design capacity of the battery to
 615 visualise how the battery life time get shorter over time.  The red
 616 line in this graph is what the previous graph considers 100 percent:
 617
 618 <p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2016-05-23-battery-stats-history.png"/></p>
 619
 620 <p>In this graph you can see that I only charge the battery to 80
 621 percent of last full capacity, and how the capacity of the battery is
 622 shrinking. :(</p>
 623
 624 <p>The last new feature is in the collector, which now will handle
 625 more hardware models.  On some hardware, Linux power supply
 626 information is stored in /sys/class/power_supply/ACAD/, while the
 627 collector previously only looked in /sys/class/power_supply/AC/.  Now
 628 both are checked to figure if there is power connected to the
 629 machine.</p>
 630
 631 <p>If you are interested in how your laptop battery is doing, please
 632 check out the
 633 <a href="https://tracker.debian.org/pkg/battery-stats">battery-stats</a>
 634 in Debian unstable, or rebuild it on Jessie to get it working on
 635 Debian stable. :) The upstream source is available from <a
