  24       <div class="date"> 5th August 2016</div>
  25       <div class="body"><p>As my regular readers probably remember, the last year I published
  26 a French and Norwegian translation of the classic
  27 <a href="http://www.free-culture.cc/">Free Culture book</a> by the
  28 founder of the Creative Commons movement, Lawrence Lessig.  A bit less
  29 known is the fact that due to the way I created the translations,
  30 using docbook and po4a, and also recreated the English original.  And
  31 because I already had created a new the PDF edition, I published it
  32 too.  The revenue from the book is sent to the Creative Commons
  33 Corporation.  So I do not earn any money from the project, I just earn
  34 the warm fuzzy feeling that the text is available for a wider audience
  35 and more people can learn why the Creative Commons is needed.</p>
  36
  37 <p>Today, just for fun, I had a look at the sales number over at
  38 Lulu.com, which take care of payment, printing and shipping.  Much to
  39 my surprise, the English edition is selling better than both the
  40 French and Norwegian edition, despite the fact that it has been
  41 available in English since it was first published.  In total, 24 paper
  42 books was sold for USD $19.99 between 2016-01-01 and 2016-07-31:</p>
  43
  44 <table border="0">
  45 <tr><th>Title / language</th><th>Quantity</th></tr>
  46 <tr><td><a href="http://www.lulu.com/shop/lawrence-lessig/culture-libre/paperback/product-22645082.html">Culture Libre / French</a></td><td>3</td></tr>

  49 </table>
  50
  51 <p>The books are available both from Lulu.com and from large book
  52 stores like Amazon and Barnes&Noble.  Most revenue, around $10 per
  53 book, is sent to the Creative Commons project when the book is sold
  54 directly by Lulu.com.  The other channels give less revenue.  The
  55 summary from Lulu tell me 10 books was sold via the Amazon channel, 10
  56 via Ingram (what is this?) and 4 directly by Lulu.  And Lulu.com tells
  57 me that the revenue sent so far this year is USD $101.42.  No idea
  58 what kind of sales numbers to expect, so I do not know if that is a
  59 good amount of sales for a 10 year old book or not.  But it make me
  60 happy that the buyers find the book, and I hope they enjoy reading it
  61 as much as I did.</p>
  62
  63 <p>The ebook edition is available for free from
  64 <a href="https://github.com/petterreinholdtsen/free-culture-lessig">Github</a>.</p>
  65
  66 <p>If you would like to translate and publish the book in your native
  67 language, I would be happy to help make it happen.  Please get in
  68 touch.</p>

  82       <div class="date"> 1st August 2016</div>
  83       <div class="body"><p>For mange år siden leste jeg en klassisk tekst som gjorde såpass
  84 inntrykk på meg at jeg husker den fortsatt, flere år senere, og bruker
  85 argumentene fra den stadig vekk.  Teksten var «The Relativity of
  86 Wrong» som Isaac Asimov publiserte i Skeptical Inquirer i 1989.  Den
  87 gir litt perspektiv rundt formidlingen av vitenskapelige resultater.
  88 Jeg har hatt lyst til å kunne dele den også med folk som ikke
  89 behersker engelsk så godt, som barn og noen av mine eldre slektninger,
  90 og har savnet å ha den tilgjengelig på norsk.  For to uker siden tok
  91 jeg meg sammen og kontaktet Asbjørn Dyrendal i foreningen Skepsis om
  92 de var interessert i å publisere en norsk utgave på bloggen sin, og da
  93 han var positiv tok jeg kontakt med Skeptical Inquirer og spurte om
  94 det var greit for dem.  I løpet av noen dager fikk vi tilbakemelding
  95 fra Barry Karr hos The Skeptical Inquirer som hadde sjekket og fått OK
  96 fra Robyn Asimov som representerte arvingene i Asmiov-familien og gikk
  97 igang med oversettingen.</p>
  98
  99 <p>Resultatet, <a href="http://www.skepsis.no/?p=1617">«Relativt
 100 feil»</a>, ble publisert på skepsis-bloggen for noen minutter siden.
 101 Jeg anbefaler deg på det varmeste å lese denne teksten og dele den med
 102 dine venner.</p>
 103
 104 <p>For å håndtere oversettelsen og sikre at original og oversettelse
 105 var i sync brukte vi git, po4a, GNU make og Transifex.  Det hele
 106 fungerte utmerket og gjorde det enkelt å dele tekstene og jobbe sammen
 107 om finpuss på formuleringene.  Hadde hosted.weblate.org latt meg
 108 opprette nye prosjekter selv i stedet for å måtte kontakte
 109 administratoren der, så hadde jeg brukt weblate i stedet.</p>

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

 135 using only free software (all of it
 136 <a href="http://github.com/Frikanalen">available from Github</a>), and
 137 is administrated using a web browser and a web API.</p>
 138
 139 <p>The TV channel is the Norwegian open channel
 140 <a href="http://www.frikanalen.no/">Frikanalen</a>, and I am involved
 141 via <a href="https://www.nuug.no/">the NUUG member association</a> in
 142 running and developing the software for the channel.  The channel is
 143 organised as a member organisation where its members can upload and
 144 broadcast what they want (think of it as Youtube for national
 145 broadcasting television).  Individuals can broadcast too.  The time
 146 slots are handled on a first come, first serve basis.  Because the
 147 channel have almost no viewers and very few active members, we can
 148 experiment with TV technology without too much flack when we make
 149 mistakes.  And thanks to the few active members, most of the slots on
 150 the schedule are free.  I see this as an opportunity to spread
 151 knowledge about technology and free software, and have a script I run
 152 regularly to fill up all the open slots the next few days with
 153 technology related video.  The end result is a channel I like to
 154 describe as Techno TV - filled with interesting talks and
 155 presentations.</p>
 156
 157 <p>It is available on channel 50 on the Norwegian national digital TV
 158 network (RiksTV).  It is also available as a multicast stream on
 159 Uninett.  And finally, it is available as
 160 <a href="http://beta.frikanalen.no/">a WebM unicast stream</a> from
 161 Frikanalen and NUUG.  Check it out. :)</p>

 175       <div class="date"> 7th July 2016</div>
 176       <div class="body"><p>Yesterday, I tried to unlock a HTC Desire HD phone, and it proved
 177 to be a slight challenge.  Here is the recipe if I ever need to do it
 178 again.  It all started by me wanting to try the recipe to set up
 179 <a href="https://blog.torproject.org/blog/mission-impossible-hardening-android-security-and-privacy">an
 180 hardened Android installation</a> from the Tor project blog on a
 181 device I had access to.  It is a old mobile phone with a broken
 182 microphone The initial idea had been to just
 183 <a href="http://wiki.cyanogenmod.org/w/Install_CM_for_ace">install
 184 CyanogenMod on it</a>, but did not quite find time to start on it
 185 until a few days ago.</p>
 186
 187 <p>The unlock process is supposed to be simple: (1) Boot into the boot
 188 loader (press volume down and power at the same time), (2) select
 189 'fastboot' before (3) connecting the device via USB to a Linux
 190 machine, (4) request the device identifier token by running 'fastboot
 191 oem get_identifier_token', (5) request the device unlocking key using
 192 the <a href="http://www.htcdev.com/bootloader/">HTC developer web
 193 site</a> and unlock the phone using the key file emailed to you.</p>
 194
 195 <p>Unfortunately, this only work fi you have hboot version 2.00.0029
 196 or newer, and the device I was working on had 2.00.0027.  This
 197 apparently can be easily fixed by downloading a Windows program and
 198 running it on your Windows machine, if you accept the terms Microsoft
 199 require you to accept to use Windows - which I do not.  So I had to
 200 come up with a different approach.  I got a lot of help from AndyCap
 201 on #nuug, and would not have been able to get this working without
 202 him.</p>
 203
 204 <p>First I needed to extract the hboot firmware from
 205 <a href="http://www.htcdev.com/ruu/PD9810000_Ace_Sense30_S_hboot_2.00.0029.exe">the
 206 windows binary for HTC Desire HD</a> downloaded as 'the RUU' from HTC.
 207 For this there is is <a href="https://github.com/kmdm/unruu/">a github
 208 project named unruu</a> using libunshield.  The unshield tool did not
 209 recognise the file format, but unruu worked and extracted rom.zip,
 210 containing the new hboot firmware and a text file describing which
 211 devices it would work for.</p>
 212
 213 <p>Next, I needed to get the new firmware into the device.  For this I
 214 followed some instructions
 215 <a href="http://www.htc1guru.com/2013/09/new-ruu-zips-posted/">available
 216 from HTC1Guru.com</a>, and ran these commands as root on a Linux
 217 machine with Debian testing:</p>
 218
 219 <p><pre>
 220 adb reboot-bootloader
 221 fastboot oem rebootRUU
 222 fastboot flash zip rom.zip
 223 fastboot flash zip rom.zip
 224 fastboot reboot
 225 </pre></p>
 226
 227 <p>The flash command apparently need to be done twice to take effect,
 228 as the first is just preparations and the second one do the flashing.
 229 The adb command is just to get to the boot loader menu, so turning the
 230 device on while holding volume down and the power button should work
 231 too.</p>
 232
 233 <p>With the new hboot version in place I could start following the
 234 instructions on the HTC developer web site.  I got the device token
 235 like this:</p>
 236
 237 <p><pre>
 238 fastboot oem get_identifier_token 2>&1 | sed 's/(bootloader) //'
 239 </pre>
 240
 241 <p>And once I got the unlock code via email, I could use it like
 242 this:</p>
 243
 244 <p><pre>
 245 fastboot flash unlocktoken Unlock_code.bin
 246 </pre></p>
 247
 248 <p>And with that final step in place, the phone was unlocked and I
 249 could start stuffing the software of my own choosing into the device.
 250 So far I only inserted a replacement recovery image to wipe the phone
 251 before I start.  We will see what happen next.  Perhaps I should
 252 install <a href="https://www.debian.org/">Debian</a> on it. :)</p>

 266       <div class="date"> 3rd July 2016</div>
 267       <div class="body"><p>For a while now, I have wanted to test
 268 <a href="https://whispersystems.org/">the Signal app</a>, as it is
 269 said to provide end to end encrypted communication and several of my
 270 friends and family are already using it.  As I by choice do not own a
 271 mobile phone, this proved to be harder than expected.  And I wanted to
 272 have the source of the client and know that it was the code used on my
 273 machine.  But yesterday I managed to get it working.  I used the
 274 Github source, compared it to the source in
 275 <a href="https://chrome.google.com/webstore/detail/signal-private-messenger/bikioccmkafdpakkkcpdbppfkghcmihk?hl=en-US">the
 276 Signal Chrome app</a> available from the Chrome web store, applied
 277 patches to use the production Signal servers, started the app and
 278 asked for the hidden "register without a smart phone" form.  Here is
 279 the recipe how I did it.</p>
 280
 281 <p>First, I fetched the Signal desktop source from Github, using
 282
 283 <pre>
 284 git clone https://github.com/WhisperSystems/Signal-Desktop.git
 285 </pre>
 286
 287 <p>Next, I patched the source to use the production servers, to be
 288 able to talk to other Signal users:</p>

 320 <p>The first part is changing the servers, and the second is updating
 321 an expiration timestamp.  This timestamp need to be updated regularly.
 322 It is set 90 days in the future by the build process (Gruntfile.js).
 323 The value is seconds since 1970 times 1000, as far as I can tell.</p>
 324
 325 <p>Based on a tip and good help from the #nuug IRC channel, I wrote a
 326 script to launch Signal in Chromium.</p>
 327
 328 <pre>
 329 #!/bin/sh
 330 cd $(dirname $0)
 331 mkdir -p userdata
 332 exec chromium \
 333   --proxy-server="socks://localhost:9050" \
 334   --user-data-dir=`pwd`/userdata --load-and-launch-app=`pwd`
 335 </pre>
 336
 337 <p> The script start the app and configure Chromium to use the Tor
 338 SOCKS5 proxy to make sure those controlling the Signal servers (today
 339 Amazon and Whisper Systems) as well as those listening on the lines
 340 will have a harder time location my laptop based on the Signal
 341 connections if they use source IP address.</p>
 342
 343 <p>When the script starts, one need to follow the instructions under
 344 "Standalone Registration" in the CONTRIBUTING.md file in the git
 345 repository.  I right clicked on the Signal window to get up the
 346 Chromium debugging tool, visited the 'Console' tab and wrote
 347 'extension.install("standalone")' on the console prompt to get the
 348 registration form.  Then I entered by land line phone number and
 349 pressed 'Call'.  5 seconds later the phone rang and a robot voice
 350 repeated the verification code three times.  After entering the number
 351 into the verification code field in the form, I could start using
 352 Signal from my laptop.
 353
 354 <p>As far as I can tell, The Signal app will leak who is talking to
 355 whom and thus who know who to those controlling the central server,
 356 but such leakage is hard to avoid with a centrally controlled server
 357 setup.  It is something to keep in mind when using Signal - the
 358 content of your chats are harder to intercept, but the meta data
 359 exposing your contact network is available to people you do not know.
 360 So better than many options, but not great.  And sadly the usage is
 361 connected to my land line, thus allowing those controlling the server
 362 to associate it to my home and person.  I would prefer it if only
 363 those I knew could tell who I was on Signal.  There are options
 364 avoiding such information leakage, but most of my friends are not
 365 using them, so I am stuck with Signal for now.</p>

 379       <div class="date"> 6th June 2016</div>
 380       <div class="body"><p>When I set out a few weeks ago to figure out
 381 <a href="http://people.skolelinux.org/pere/blog/What_is_the_best_multimedia_player_in_Debian_.html">which
 382 multimedia player in Debian claimed to support most file formats /
 383 MIME types</a>, I was a bit surprised how varied the sets of MIME types
 384 the various players claimed support for.  The range was from 55 to 130
 385 MIME types.  I suspect most media formats are supported by all
 386 players, but this is not really reflected in the MimeTypes values in
 387 their desktop files.  There are probably also some bogus MIME types
 388 listed, but it is hard to identify which one this is.</p>
 389
 390 <p>Anyway, in the mean time I got in touch with upstream for some of
 391 the players suggesting to add more MIME types to their desktop files,
 392 and decided to spend some time myself improving the situation for my
 393 favorite media player VLC.  The fixes for VLC entered Debian unstable
 394 yesterday. The complete list of MIME types can be seen on the
 395 <a href="https://wiki.debian.org/DebianMultimedia/PlayerSupport">Multimedia
 396 player MIME type support status</a> Debian wiki page.</p>
 397
 398 <p>The new "best" multimedia player in Debian?  It is VLC, followed by
 399 totem, parole, kplayer, gnome-mpv, mpv, smplayer, mplayer-gui and
 400 kmplayer.  I am sure some of the other players desktop files support
 401 several of the formats currently listed as working only with vlc,
 402 toten and parole.</p>
 403
 404 <p>A sad observation is that only 14 MIME types are listed as
 405 supported by all the tested multimedia players in Debian in their
 406 desktop files: audio/mpeg, audio/vnd.rn-realaudio, audio/x-mpegurl,
 407 audio/x-ms-wma, audio/x-scpls, audio/x-wav, video/mp4, video/mpeg,
 408 video/quicktime, video/vnd.rn-realvideo, video/x-matroska,
 409 video/x-ms-asf, video/x-ms-wmv and video/x-msvideo.  Personally I find
 410 it sad that video/ogg and video/webm is not supported by all the media
 411 players in Debian.  As far as I can tell, all of them can handle both
 412 formats.</p>

 426       <div class="date"> 5th June 2016</div>
 427       <div class="body"><p>Many years ago, when koffice was fresh and with few users, I
 428 decided to test its presentation tool when making the slides for a
 429 talk I was giving for NUUG on Japhar, a free Java virtual machine.  I
 430 wrote the first draft of the slides, saved the result and went to bed
 431 the day before I would give the talk.  The next day I took a plane to
 432 the location where the meeting should take place, and on the plane I
 433 started up koffice again to polish the talk a bit, only to discover
 434 that kpresenter refused to load its own data file.  I cursed a bit and
 435 started making the slides again from memory, to have something to
 436 present when I arrived.  I tested that the saved files could be
 437 loaded, and the day seemed to be rescued.  I continued to polish the
 438 slides until I suddenly discovered that the saved file could no longer
 439 be loaded into kpresenter.  In the end I had to rewrite the slides
 440 three times, condensing the content until the talk became shorter and
 441 shorter.  After the talk I was able to pinpoint the problem &ndash;
 442 kpresenter wrote inline images in a way itself could not understand.
 443 Eventually that bug was fixed and kpresenter ended up being a great
 444 program to make slides.  The point I'm trying to make is that we
 445 expect a program to be able to load its own data files, and it is
 446 embarrassing to its developers if it can't.</p>
 447
 448 <p>Did you ever experience a program failing to load its own data
 449 files from the desktop file browser?  It is not a uncommon problem.  A
 450 while back I discovered that the screencast recorder
 451 gtk-recordmydesktop would save an Ogg Theora video file the KDE file
 452 browser would refuse to open.  No video player claimed to understand
 453 such file.  I tracked down the cause being <tt>file --mime-type</tt>
 454 returning the application/ogg MIME type, which no video player I had
 455 installed listed as a MIME type they would understand.  I asked for
 456 <a href="http://bugs.gw.com/view.php?id=382">file to change its
 457 behavour</a> and use the MIME type video/ogg instead.  I also asked
 458 several video players to add video/ogg to their desktop files, to give
 459 the file browser an idea what to do about Ogg Theora files.  After a
 460 while, the desktop file browsers in Debian started to handle the
 461 output from gtk-recordmydesktop properly.</p>
 462
 463 <p>But history repeats itself.  A few days ago I tested the music
 464 system Rosegarden again, and I discovered that the KDE and xfce file
 465 browsers did not know what to do with the Rosegarden project files
 466 (*.rg).  I've reported <a href="http://bugs.debian.org/825993">the
 467 rosegarden problem to BTS</a> and a fix is commited to git and will be
 468 included in the next upload.  To increase the chance of me remembering
 469 how to fix the problem next time some program fail to load its files
 470 from the file browser, here are some notes on how to fix it.</p>
 471
 472 <p>The file browsers in Debian in general operates on MIME types.
 473 There are two sources for the MIME type of a given file.  The output from
 474 <tt>file --mime-type</tt> mentioned above, and the content of the
 475 shared MIME type registry (under /usr/share/mime/).  The file MIME
 476 type is mapped to programs supporting the MIME type, and this
 477 information is collected from
 478 <a href="https://www.freedesktop.org/wiki/Specifications/desktop-entry-spec/">the
 479 desktop files</a> available in /usr/share/applications/.  If there is
 480 one desktop file claiming support for the MIME type of the file, it is
 481 activated when asking to open a given file.  If there are more, one
 482 can normally select which one to use by right-clicking on the file and
 483 selecting the wanted one using 'Open with' or similar.  In general
 484 this work well.  But it depend on each program picking a good MIME
 485 type (preferably
 486 <a href="http://www.iana.org/assignments/media-types/media-types.xhtml">a
 487 MIME type registered with IANA</a>), file and/or the shared MIME
 488 registry recognizing the file and the desktop file to list the MIME
 489 type in its list of supported MIME types.</p>
 490
 491 <p>The <tt>/usr/share/mime/packages/rosegarden.xml</tt> entry for
 492 <a href="http://www.freedesktop.org/wiki/Specifications/shared-mime-info-spec">the
 493 Shared MIME database</a> look like this:</p>
 494
 495 <p><blockquote><pre>
 496 &lt;?xml version="1.0" encoding="UTF-8"?&gt;
 497 &lt;mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info"&gt;
 498   &lt;mime-type type="audio/x-rosegarden"&gt;
 499     &lt;sub-class-of type="application/x-gzip"/&gt;
 500     &lt;comment&gt;Rosegarden project file&lt;/comment&gt;
 501     &lt;glob pattern="*.rg"/&gt;
 502   &lt;/mime-type&gt;
 503 &lt;/mime-info&gt;
 504 </pre></blockquote></p>
 505
 506 <p>This states that audio/x-rosegarden is a kind of application/x-gzip
 507 (it is a gzipped XML file).  Note, it is much better to use an
 508 official MIME type registered with IANA than it is to make up ones own
 509 unofficial ones like the x-rosegarden type used by rosegarden.</p>
 510
 511 <p>The desktop file of the rosegarden program failed to list
 512 audio/x-rosegarden in its list of supported MIME types, causing the
 513 file browsers to have no idea what to do with *.rg files:</p>
 514
 515 <p><blockquote><pre>
 516 % grep Mime /usr/share/applications/rosegarden.desktop
 517 MimeType=audio/x-rosegarden-composition;audio/x-rosegarden-device;audio/x-rosegarden-project;audio/x-rosegarden-template;audio/midi;
 518 X-KDE-NativeMimeType=audio/x-rosegarden-composition
 519 %
 520 </pre></blockquote></p>
 521
 522 <p>The fix was to add "audio/x-rosegarden;" at the end of the
 523 MimeType= line.</p>
 524
 525 <p>If you run into a file which fail to open the correct program when
 526 selected from the file browser, please check out the output from
 527 <tt>file --mime-type</tt> for the file, ensure the file ending and
 528 MIME type is registered somewhere under /usr/share/mime/ and check
 529 that some desktop file under /usr/share/applications/ is claiming
 530 support for this MIME type.  If not, please report a bug to have it
 531 fixed. :)</p>

 545       <div class="date">28th May 2016</div>
 546       <div class="body"><p>A little more than 11 years ago, one of the creators of Tor, and
 547 the current President of <a href="https://www.torproject.org/">the Tor
 548 project</a>, Roger Dingledine, gave a talk for the members of the
 549 <a href="http://www.nuug.no/">Norwegian Unix User group</a> (NUUG).  A
 550 video of the talk was recorded, and today, thanks to the great help
 551 from David Noble, I finally was able to publish the video of the talk
 552 on Frikanalen, the Norwegian open channel TV station where NUUG
 553 currently publishes its talks.  You can
 554 <a href="http://frikanalen.no/se">watch the live stream using a web
 555 browser</a> with WebM support, or check out the recording on the video
 556 on demand page for the talk
 557 "<a href="http://beta.frikanalen.no/video/625599">Tor: Anonymous
 558 communication for the US Department of Defence...and you.</a>".</p>

 566
 567 <p>I guess the gist of the talk can be summarised quite simply: If you
 568 want to help the military in USA (and everyone else), use Tor. :)</p>

 582       <div class="date">25th May 2016</div>
 583       <div class="body"><p><a href="https://tracker.debian.org/pkg/isenkram">The isenkram
 584 system</a> is a user-focused solution in Debian for handling hardware
 585 related packages.  The idea is to have a database of mappings between
 586 hardware and packages, and pop up a dialog suggesting for the user to
 587 install the packages to use a given hardware dongle.  Some use cases
 588 are when you insert a Yubikey, it proposes to install the software
 589 needed to control it; when you insert a braille reader list it
 590 proposes to install the packages needed to send text to the reader;
 591 and when you insert a ColorHug screen calibrator it suggests to
 592 install the driver for it.  The system work well, and even have a few
 593 command line tools to install firmware packages and packages for the
 594 hardware already in the machine (as opposed to hotpluggable hardware).</p>
 595
 596 <p>The system was initially written using aptdaemon, because I found
 597 good documentation and example code on how to use it.  But aptdaemon
 598 is going away and is generally being replaced by
 599 <a href="http://www.freedesktop.org/software/PackageKit/">PackageKit</a>,
 600 so Isenkram needed a rewrite.  And today, thanks to the great patch
 601 from my college Sunil Mohan Adapa in the FreedomBox project, the
 602 rewrite finally took place.  I've just uploaded a new version of
 603 Isenkram into Debian Unstable with the patch included, and the default
 604 for the background daemon is now to use PackageKit.  To check it out,
 605 install the <tt>isenkram</tt> package and insert some hardware dongle
 606 and see if it is recognised.</p>
 607
 608 <p>If you want to know what kind of packages isenkram would propose for
 609 the machine it is running on, you can check out the isenkram-lookup
 610 program.  This is what it look like on a Thinkpad X230:</p>
 611
 612 <p><blockquote><pre>
 613 % isenkram-lookup
 614 bluez
 615 cheese
 616 fprintd
 617 fprintd-demo
 618 gkrellm-thinkbat
 619 hdapsd
 620 libpam-fprintd
 621 pidgin-blinklight
 622 thinkfan
 623 tleds
 624 tp-smapi-dkms
 625 tp-smapi-source
 626 tpb
 627 %p
 628 </pre></blockquote></p>
 629
 630 <p>The hardware mappings come from several places.  The preferred way
 631 is for packages to announce their hardware support using
 632 <a href="https://www.freedesktop.org/software/appstream/docs/">the
 633 cross distribution appstream system</a>.
 634 See
 635 <a href="http://people.skolelinux.org/pere/blog/tags/isenkram/">previous
 636 blog posts about isenkram</a> to learn how to do that.</p>

 650       <div class="date">23rd May 2016</div>
 651       <div class="body"><p>Yesterday I updated the
 652 <a href="https://tracker.debian.org/pkg/battery-stats">battery-stats
 653 package in Debian</a> with a few patches sent to me by skilled and
 654 enterprising users.  There were some nice user and visible changes.
 655 First of all, both desktop menu entries now work.  A design flaw in
 656 one of the script made the history graph fail to show up (its PNG was
 657 dumped in ~/.xsession-errors) if no controlling TTY was available.
 658 The script worked when called from the command line, but not when
 659 called from the desktop menu.  I changed this to look for a DISPLAY
 660 variable or a TTY before deciding where to draw the graph, and now the
 661 graph window pop up as expected.</p>
 662
 663 <p>The next new feature is a discharge rate estimator in one of the
 664 graphs (the one showing the last few hours).  New is also the user of
 665 colours showing charging in blue and discharge in red.  The percentages
 666 of this graph is relative to last full charge, not battery design
 667 capacity.</p>
 668
 669 <p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2016-05-23-battery-stats-rate.png"/></p>
 670
 671 <p>The other graph show the entire history of the collected battery
 672 statistics, comparing it to the design capacity of the battery to
 673 visualise how the battery life time get shorter over time.  The red
 674 line in this graph is what the previous graph considers 100 percent:
 675
 676 <p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2016-05-23-battery-stats-history.png"/></p>
 677
 678 <p>In this graph you can see that I only charge the battery to 80
 679 percent of last full capacity, and how the capacity of the battery is
 680 shrinking. :(</p>
 681
 682 <p>The last new feature is in the collector, which now will handle
 683 more hardware models.  On some hardware, Linux power supply
 684 information is stored in /sys/class/power_supply/ACAD/, while the
 685 collector previously only looked in /sys/class/power_supply/AC/.  Now
 686 both are checked to figure if there is power connected to the
 687 machine.</p>
 688
 689 <p>If you are interested in how your laptop battery is doing, please
 690 check out the
 691 <a href="https://tracker.debian.org/pkg/battery-stats">battery-stats</a>
 692 in Debian unstable, or rebuild it on Jessie to get it working on
 693 Debian stable. :) The upstream source is available from <a
