-<p>Yesterday I updated the battery-stats package in Debian with a few
-patches sent to me by skilled and enterprising users.  There are a few
-user nice and visible changes.  First of all, both the desktop menu
-entries now work.  A design flaw in one of the script made it fail if
-no controlling TTY was available.  So the script worked when called
-from the command line, but not when called from the desktop menu.</p>

+<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).  It also got colors
-showing charging in blue and discharge in red.  The percentages of
-this graph is relative to last full charge, not battery design
+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>The other graph show the entire history of the collected battery
-statistics, comparing it to the design capacity of the battery to see
-how the battery life time get shorter over time.  The red line in this
-graph is what the previous graph considers 100 percent:
+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>You can see here 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.</p>
