+ <div class="body">
+ <p>A little more than 11 years ago, one of the creators of Tor, and
+the current President of <a href="https://www.torproject.org/">the Tor
+project</a>, Roger Dingledine, gave a talk for the members of the
+<a href="http://www.nuug.no/">Norwegian Unix User group</a> (NUUG). A
+video of the talk was recorded, and today, thanks to the great help
+from David Noble, I finally was able to publish the video of the talk
+on Frikanalen, the Norwegian open channel TV station where NUUG
+currently publishes its talks. You can
+<a href="http://frikanalen.no/se">watch the live stream using a web
+browser</a> with WebM support, or check out the recording on the video
+on demand page for the talk
+"<a href="http://beta.frikanalen.no/video/625599">Tor: Anonymous
+communication for the US Department of Defence...and you.</a>".</p>
+
+<p>Here is the video included for those of you using browsers with
+HTML video and Ogg Theora support:</p>

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

+ <p><a href="https://tracker.debian.org/pkg/isenkram">The isenkram
+system</a> is a user-focused solution in Debian for handling hardware
+related packages. The idea is to have a database of mappings between
+hardware and packages, and pop up a dialog suggesting for the user to
+install the packages to use a given hardware dongle. Some use cases
+are when you insert a Yubikey, it proposes to install the software
+needed to control it; when you insert a braille reader list it
+proposes to install the packages needed to send text to the reader;
+and when you insert a ColorHug screen calibrator it suggests to
+install the driver for it. The system work well, and even have a few
+command line tools to install firmware packages and packages for the
+hardware already in the machine (as opposed to hotpluggable hardware).</p>
+
+<p>The system was initially written using aptdaemon, because I found
+good documentation and example code on how to use it. But aptdaemon
+is going away and is generally being replaced by
+<a href="http://www.freedesktop.org/software/PackageKit/">PackageKit</a>,
+so Isenkram needed a rewrite. And today, thanks to the great patch
+from my college Sunil Mohan Adapa in the FreedomBox project, the
+rewrite finally took place. I've just uploaded a new version of
+Isenkram into Debian Unstable with the patch included, and the default
+for the background daemon is now to use PackageKit. To check it out,
+install the <tt>isenkram</tt> package and insert some hardware dongle
+and see if it is recognised.</p>
+
+<p>If you want to know what kind of packages isenkram would propose for
+the machine it is running on, you can check out the isenkram-lookup
+program. This is what it look like on a Thinkpad X230:</p>
+
+<p><blockquote><pre>
+% isenkram-lookup
+bluez
+cheese
+fprintd
+fprintd-demo
+gkrellm-thinkbat
+hdapsd
+libpam-fprintd
+pidgin-blinklight
+thinkfan
+tleds
+tp-smapi-dkms
+tp-smapi-source
+tpb
+%p
+</pre></blockquote></p>
+
+<p>The hardware mappings come from several places. The preferred way
+is for packages to announce their hardware support using
+<a href="https://www.freedesktop.org/software/appstream/docs/">the
+cross distribution appstream system</a>.
+See
+<a href="http://people.skolelinux.org/pere/blog/tags/isenkram/">previous
+blog posts about isenkram</a> to learn how to do that.</p>

+ <div class="body">
+ <p>Yesterday I updated the
+<a href="https://tracker.debian.org/pkg/battery-stats">battery-stats
+package in Debian</a> with a few patches sent to me by skilled and
+enterprising users. There were some nice user and visible changes.
+First of all, both desktop menu entries now work. A design flaw in
+one of the script made the history graph fail to show up (its PNG was
+dumped in ~/.xsession-errors) if no controlling TTY was available.
+The script worked when called from the command line, but not when
+called from the desktop menu. I changed this to look for a DISPLAY
+variable or a TTY before deciding where to draw the graph, and now the
+graph window pop up as expected.</p>
+
+<p>The next new feature is a discharge rate estimator in one of the
+graphs (the one showing the last few hours). New is also the user of
+colours showing charging in blue and discharge in red. The percentages
+of this graph is relative to last full charge, not battery design
+capacity.</p>
+
+<p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2016-05-23-battery-stats-rate.png"/></p>
+
+<p>The other graph show the entire history of the collected battery
+statistics, comparing it to the design capacity of the battery to
+visualise how the battery life time get shorter over time. The red
+line in this graph is what the previous graph considers 100 percent:
+
+<p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2016-05-23-battery-stats-history.png"/></p>
+
+<p>In this graph you can see that I only charge the battery to 80
+percent of last full capacity, and how the capacity of the battery is
+shrinking. :(</p>
+
+<p>The last new feature is in the collector, which now will handle
+more hardware models. On some hardware, Linux power supply
+information is stored in /sys/class/power_supply/ACAD/, while the
+collector previously only looked in /sys/class/power_supply/AC/. Now
+both are checked to figure if there is power connected to the
+machine.</p>
+
+<p>If you are interested in how your laptop battery is doing, please
+check out the
+<a href="https://tracker.debian.org/pkg/battery-stats">battery-stats</a>
+in Debian unstable, or rebuild it on Jessie to get it working on
+Debian stable. :) The upstream source is available from <a
+href="https://github.com/petterreinholdtsen/battery-stats">github</a>.
+Patches are very welcome.</p>

+ <p>A few weeks ago the French paperback edition of Lawrence Lessigs
+2004 book Cultura Libre was published. Today I noticed that the book
+is now available from book stores. You can now buy it from
+<a href="http://www.amazon.com/Culture-Libre-French-Lawrence-Lessig/dp/8269018260">Amazon</a>
+($19.99),
+<a href="http://www.barnesandnoble.com/w/culture-libre-lawrence-lessig/1123776705">Barnes

+<a href="http://www.lulu.com/shop/lawrence-lessig/culture-libre/paperback/product-22645082.html">Lulu.com</a>
+($19.99). The revenue is donated to the Creative Commons project. If
+you buy from Lulu.com, they currently get $10.59, while if you buy
+from one of the book stores most of the revenue go to the book store
+and the Creative Commons project get much (not sure how much
+less).</p>
+
+<p>I was a bit surprised to discover that there is a kindle edition
+sold by Amazon Digital Services LLC on Amazon. Not quite sure how
+that edition was created, but if you want to download a electronic
+edition (PDF, EPUB, Mobi) generated from the same files used to create
+the paperback edition, they are
+<a href="https://github.com/petterreinholdtsen/free-culture-lessig">available
