+               <description>&lt;p&gt;Back in September, I blogged about
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/The_life_and_death_of_a_laptop_battery.html&quot;&gt;the
+system I wrote to collect statistics about my laptop battery&lt;/a&gt;, and
+how it showed the decay and death of this battery (now replaced).  I
+created a simple deb package to handle the collection and graphing,
+but did not want to upload it to Debian as there were already
+&lt;a href=&quot;https://tracker.debian.org/pkg/battery-stats&quot;&gt;a battery-stats
+package in Debian&lt;/a&gt; that should do the same thing, and I did not see
+a point of uploading a competing package when battery-stats could be
+fixed instead.  I reported a few bugs about its non-function, and
+hoped someone would step in and fix it.  But no-one did.&lt;/p&gt;
+
+&lt;p&gt;I got tired of waiting a few days ago, and took matters in my own
+hands.  The end result is that I am now the new upstream developer of
+battery stats (&lt;a href=&quot;https://github.com/petterreinholdtsen/battery-stats&quot;&gt;available from github&lt;/a&gt;) and part of the team maintaining
+battery-stats in Debian, and the package in Debian unstable is finally
+able to collect battery status using the /sys/class/power_supply/
+information provided by the Linux kernel.  If you install the
+battery-stats package from unstable now, you will be able to get a
+graph of the current battery fill level, to get some idea about the
+status of the battery.  The source package build and work just fine in
+Debian testing and stable (and probably oldstable too, but I have not
+tested).  The default graph you get for that system look like this:&lt;/p&gt;
+
+&lt;p align=&quot;center&quot;&gt;&lt;img src=&quot;http://people.skolelinux.org/pere/blog/images/2016-03-15-battery-stats-graph-example.png&quot; width=&quot;70%&quot; align=&quot;center&quot;&gt;&lt;/p&gt;
+
+&lt;p&gt;My plans for the future is to merge my old scripts into the
+battery-stats package, as my old scripts collected a lot more details
+about the battery.  The scripts are merged into the upstream
+battery-stats git repository already, but I am not convinced they work
+yet, as I changed a lot of paths along the way.  Will have to test a
+bit more before I make a new release.&lt;/p&gt;
+
+&lt;p&gt;I will also consider changing the file format slightly, as I
+suspect the way I combine several values into one field might make it
+impossible to know the type of the value when using it for processing
+and graphing.&lt;/p&gt;
+
+&lt;p&gt;If you would like I would like to keep an close eye on your laptop
+battery, check out the battery-stats package in
+&lt;a href=&quot;https://tracker.debian.org/pkg/battery-stats&quot;&gt;Debian&lt;/a&gt; and
+on
+&lt;a href=&quot;https://github.com/petterreinholdtsen/battery-stats&quot;&gt;github&lt;/a&gt;.
+I would love some help to improve the system further.&lt;/p&gt;

-               <description>&lt;p&gt;I&#39;ve needed a new OpenPGP key for a while, but have not had time to
-set it up properly.  I wanted to generate it offline and have it
-available on &lt;a href=&quot;http://shop.kernelconcepts.de/#openpgp&quot;&gt;a OpenPGP
-smart card&lt;/a&gt; for daily use, and learning how to do it and finding
-time to sit down with an offline machine almost took forever.  But
-finally I&#39;ve been able to complete the process, and have now moved
-from my old GPG key to a new GPG key.  See
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/images/2015-11-17-new-gpg-key-transition.txt&quot;&gt;the
-full transition statement, signed with both my old and new key&lt;/a&gt; for
-the details.  This is my new key:&lt;/p&gt;

-&lt;p&gt;The key can be downloaded from the OpenPGP key servers, signed by
-my old key.&lt;/p&gt;

-&lt;p&gt;If you signed my old key
-(&lt;a href=&quot;http://pgp.cs.uu.nl/stats/DB4CCC4B2A30D729.html&quot;&gt;DB4CCC4B2A30D729&lt;/a&gt;),
-I&#39;d very much appreciate a signature on my new key, details and
-instructions in the transition statement. I m happy to reciprocate if
-you have a similarly signed transition statement to present.&lt;/p&gt;
