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> + + + + + Discharge rate estimate in new battery statistics collector for Debian + http://people.skolelinux.org/pere/blog/Discharge_rate_estimate_in_new_battery_statistics_collector_for_Debian.html + http://people.skolelinux.org/pere/blog/Discharge_rate_estimate_in_new_battery_statistics_collector_for_Debian.html + Mon, 23 May 2016 09:35:00 +0200 + <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>As usual, if you use Bitcoin and want to show your support of my +activities, please send Bitcoin donations to my address +<b><a href="bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b">15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b</a></b>.</p> + + + + + French edition of Lawrence Lessigs book Cultura Libre on Amazon and Barnes & Noble + http://people.skolelinux.org/pere/blog/French_edition_of_Lawrence_Lessigs_book_Cultura_Libre_on_Amazon_and_Barnes___Noble.html + http://people.skolelinux.org/pere/blog/French_edition_of_Lawrence_Lessigs_book_Cultura_Libre_on_Amazon_and_Barnes___Noble.html + Sat, 21 May 2016 10:50:00 +0200 + <p>A few weeks ago the French paperback edition of Lawrence Lessigs +2004 book Cultura Libre was published.
