  24       <div class="date"> 5th August 2016</div>
  25       <div class="body"><p>As my regular readers probably remember, I published a French and
  26 Norwegian translation of the classic Free Culture book by the founder
  27 of the Creative Commons movement, Lawrence Lessig, the last year.  A
  28 bit less known is the fact that due to the way I created the
  29 translations, using docbook and po4a, and also recreated the English
  30 original.  And because I already had created a new the PDF edition, I
  31 published it too.  The revenue from the book is sent to the Creative
  32 Commons Corporation.  So I do not earn any money from the project, I
  33 just earn the warm fuzzy feeling that the text is available for a
  34 wider audience and more people can learn why the Creative Commons is
  35 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 summary from Lulu tell me 10 books was sold
  55 via the Amazon channel, 10 via Ingram (what is this?) and 4 directly
  56 by Lulu.  And Lulu.com tells me that the revenue sent so far this year
  57 is USD $101.42.  No idea what kind of sales numbers to expect, so I do
  58 not know if that is a good amount of sales for a 10 year old book or
  59 not.  But it make me happy that the buyers find the book, and I hope
  60 they enjoy reading it as much as I did.</p>
  61
  62 <p>The ebook edition is available for free from
  63 <a href="https://github.com/petterreinholdtsen/free-culture-lessig">Github</a>.</p>
  64
  65 <p>If you would like to translate and publish the book in your native
  66 language, I would be happy to help make it happen.  Please get in
  67 touch.</p>

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

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

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

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

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

 318
 319 <p>The first part is changing the servers, and the second is updating
 320 an expiration timestamp.  This timestamp need to be updated regularly.
 321 It is set 90 days in the future by the build process (Gruntfile.js).
 322 The value is seconds since 1970 times 1000, as far as I can tell.</p>
 323
 324 <p>Based on a tip and good help from the #nuug IRC channel, I wrote a
 325 script to launch Signal in Chromium.</p>
 326
 327 <pre>
 328 #!/bin/sh
 329 cd $(dirname $0)
 330 mkdir -p userdata
 331 exec chromium \
 332   --proxy-server="socks://localhost:9050" \
 333   --user-data-dir=`pwd`/userdata --load-and-launch-app=`pwd`
 334 </pre>
 335
 336 <p> The script start the app and configure Chromium to use the Tor
 337 SOCKS5 proxy to make sure those controlling the Signal servers (today
 338 Amazon and Whisper Systems) as well as those listening on the lines
 339 will have a harder time location my laptop based on the Signal
 340 connections if they use source IP address.</p>
 341
 342 <p>When the script starts, one need to follow the instructions under
 343 "Standalone Registration" in the CONTRIBUTING.md file in the git
 344 repository.  I right clicked on the Signal window to get up the
 345 Chromium debugging tool, visited the 'Console' tab and wrote
 346 'extension.install("standalone")' on the console prompt to get the
 347 registration form.  Then I entered by land line phone number and
 348 pressed 'Call'.  5 seconds later the phone rang and a robot voice
 349 repeated the verification code three times.  After entering the number
 350 into the verification code field in the form, I could start using
 351 Signal from my laptop.
 352
 353 <p>As far as I can tell, The Signal app will leak who is talking to
 354 whom and thus who know who to those controlling the central server,
 355 but such leakage is hard to avoid with a centrally controlled server
 356 setup.  It is something to keep in mind when using Signal - the
 357 content of your chats are harder to intercept, but the meta data
 358 exposing your contact network is available to people you do not know.
 359 So better than many options, but not great.  And sadly the usage is
 360 connected to my land line, thus allowing those controlling the server
 361 to associate it to my home and person.  I would prefer it if only
 362 those I knew could tell who I was on Signal.  There are options
 363 avoiding such information leakage, but most of my friends are not
 364 using them, so I am stuck with Signal for now.</p>

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

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

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

 565
 566 <p>I guess the gist of the talk can be summarised quite simply: If you
 567 want to help the military in USA (and everyone else), use Tor. :)</p>

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

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