  32         <p>Since this morning, the battery-stats package in Debian include an
  33 extended collector that will collect the complete battery history for
  34 later processing and graphing.  The original collector store the
  35 battery level as percentage of last full level, while the new
  36 collector also record battery vendor, model, serial number, design
  37 full level, last full level and current battery level.  This make it
  38 possible to predict the lifetime of the battery as well as visualise
  39 the energy flow when the battery is charging or discharging.</p>
  40
  41 <p>The new tools are available in <tt>/usr/share/battery-stats/</tt>
  42 in the version 0.5.1 package in unstable.  Get the new battery level graph
  43 and lifetime prediction by running:
  44
  45 <p><pre>
  46 /usr/share/battery-stats/battery-stats-graph /var/log/battery-stats.csv
  47 </pre></p>
  48
  49 <p>Or select the 'Battery Level Graph' from your application menu.</p>
  50
  51 <p>The flow in/out of the battery can be seen by running (no menu
  52 entry yet):</p>
  53
  54 <p><pre>
  55 /usr/share/battery-stats/battery-stats-graph-flow
  56 </pre></p>
  57
  58 <p>I'm not quite happy with the way the data is visualised, at least
  59 when there are few data points.  The graphs look a bit better with a
  60 few years of data.</p>
  61
  62 <p>A while back one important feature I use in the battery stats
  63 collector broke in Debian.  The scripts in
  64 <tt>/usr/lib/pm-utils/power.d/</tt> were no longer executed.  I
  65 suspect it happened when Jessie started using systemd, but I do not
  66 know.  The issue is reported as
  67 <a href="https://bugs.debian.org/818649">bug #818649</a> against
  68 pm-utils.  I managed to work around it by adding an udev rule to call
  69 the collector script every time the power connector is connected and
  70 disconnected.  With this fix in place it was finally time to make a
  71 new release of the package, and get it into Debian.</p>
  72
  73 <p>If you are interested in how your laptop battery is doing, please
  74 check out the
  75 <a href="https://tracker.debian.org/pkg/battery-stats">battery-stats</a>
  76 in Debian unstable, or rebuild it on Jessie to get it working on
  77 Debian stable. :) The upstream source is available from
  78 <a href="https://github.com/petterreinholdtsen/battery-stats">github</a>.
  79 As always, patches are very welcome.</p>

  99       <div class="body">
 100         <p>Back in 2013 I proposed
 101 <a href="http://people.skolelinux.org/pere/blog/_Electronic__paper_invoices___using_vCard_in_a_QR_code.html">a
 102 way to make paper and PDF invoices easier to process electronically by
 103 adding a QR code with the key information about the invoice</a>.  I
 104 suggested using vCard field definition, to get some standard format
 105 for name and address, but any format would work.  I did not do
 106 anything about the proposal, but hoped someone one day would make
 107 something like it.  It would make it possible to efficiently send
 108 machine readable invoices directly between seller and buyer.</p>
 109
 110 <p>This was the background when I came across a proposal and
 111 specification from the web based accounting and invoicing supplier
 112 <a href="http://www.visma.com/">Visma</a> in Sweden called
 113 <a href="http://usingqr.com/">UsingQR</a>.  Their PDF invoices contain
 114 a QR code with the key information of the invoice in JSON format.
 115 This is the typical content of a QR code following the UsingQR
 116 specification (based on a real world example, some numbers replaced to
 117 get a more bogus entry).  I've reformatted the JSON to make it easier
 118 to read.  Normally this is all on one long line:</p>
 119
 120 <p><img src="http://people.skolelinux.org/pere/blog/images/2016-03-19-qr-invoice.png" align="right"><pre>
 121 {
 122  "vh":500.00,
 123  "vm":0,
 124  "vl":0,
 125  "uqr":1,
 126  "tp":1,
 127  "nme":"Din Leverandør",
 128  "cc":"NO",
 129  "cid":"997912345 MVA",
 130  "iref":"12300001",
 131  "idt":"20151022",
 132  "ddt":"20151105",
 133  "due":2500.0000,
 134  "cur":"NOK",
 135  "pt":"BBAN",
 136  "acc":"17202612345",
 137  "bc":"BIENNOK1",
 138  "adr":"0313 OSLO"
 139 }
 140 </pre></p>
 141
 142 </p>The interpretation of the fields can be found in the
 143 <a href="http://usingqr.com/wp-content/uploads/2014/06/UsingQR_specification1.pdf">format
 144 specification</a> (revision 2 from june 2014).  The format seem to
 145 have most of the information needed to handle accounting and payment
 146 of invoices, at least the fields I have needed so far here in
 147 Norway.</p>
 148
 149 <p>Unfortunately, the site and document do not mention anything about
 150 the patent, trademark and copyright status of the format and the
 151 specification.  Because of this, I asked the people behind it back in
 152 November to clarify.  Ann-Christine Savlid (ann-christine.savlid (at)
 153 visma.com) replied that Visma had not applied for patent or trademark
 154 protection for this format, and that there were no copyright based
 155 usage limitations for the format.  I urged her to make sure this was
 156 explicitly written on the web pages and in the specification, but
 157 unfortunately this has not happened yet.  So I guess if there is
 158 submarine patents, hidden trademarks or a will to sue for copyright
 159 infringements, those starting to use the UsingQR format might be at
 160 risk, but if this happen there is some legal defense in the fact that
 161 the people behind the format claimed it was safe to do so.  At least
 162 with patents, there is always
 163 <a href="http://www.paperspecs.com/paper-news/beware-the-qr-code-patent-trap/">a
 164 chance of getting sued...</a></p>
 165
 166 <p>I also asked if they planned to maintain the format in an
 167 independent standard organization to give others more confidence that
 168 they would participate in the standardization process on equal terms
 169 with Visma, but they had no immediate plans for this.  Their plan was
 170 to work with banks to try to get more users of the format, and
 171 evaluate the way forward if the format proved to be popular.  I hope
 172 they conclude that using an open standard organisation like
 173 <a href="http://www.ietf.org/">IETF</a> is the correct place to
 174 maintain such specification.</p>
 175
 176 <p><strong>Update 2016-03-20</strong>: Via Twitter I became aware of
 177 <a href="https://news.ycombinator.com/item?id=11319492">some comments
 178 about this blog post</a> that had several useful links and references to
 179 similar systems.  In the Czech republic, the Czech Banking Association
 180 standard #26, with short name SPAYD, uses QR codes with payment
 181 information.  More information is available from the Wikipedia page on
 182 <a href="https://en.wikipedia.org/wiki/Short_Payment_Descriptor">Short
 183 Payment Descriptor</a>.  And in Germany, there is a system named
 184 <a href="http://www.bezahlcode.de/">BezahlCode</a>,
 185 (<a href="http://www.bezahlcode.de/wp-content/uploads/BezahlCode_TechDok.pdf">specification
 186 v1.8 2013-12-05 available as PDF</a>), which uses QR codes with
 187 URL-like formatting using "bank:" as the URI schema/protocol to
 188 provide the payment information.  There is also the
 189 <a href="http://www.ferd-net.de/front_content.php?idcat=231">ZUGFeRD</a>
 190 file format that perhaps could be transfered using QR codes, but I am
 191 not sure if it is done already.  Last, in Bolivia there are reports
 192 that tax information since november 2014 need to be printed in QR
 193 format on invoices.  I have not been able to track down a
 194 specification for this format, because of my limited language skill
 195 sets.</p>

 215       <div class="body">
 216         <p>Back in September, I blogged about
 217 <a href="http://people.skolelinux.org/pere/blog/The_life_and_death_of_a_laptop_battery.html">the
 218 system I wrote to collect statistics about my laptop battery</a>, and
 219 how it showed the decay and death of this battery (now replaced).  I
 220 created a simple deb package to handle the collection and graphing,
 221 but did not want to upload it to Debian as there were already
 222 <a href="https://tracker.debian.org/pkg/battery-stats">a battery-stats
 223 package in Debian</a> that should do the same thing, and I did not see
 224 a point of uploading a competing package when battery-stats could be
 225 fixed instead.  I reported a few bugs about its non-function, and
 226 hoped someone would step in and fix it.  But no-one did.</p>
 227
 228 <p>I got tired of waiting a few days ago, and took matters in my own
 229 hands.  The end result is that I am now the new upstream developer of
 230 battery stats (<a href="https://github.com/petterreinholdtsen/battery-stats">available from github</a>) and part of the team maintaining
 231 battery-stats in Debian, and the package in Debian unstable is finally
 232 able to collect battery status using the <tt>/sys/class/power_supply/</tt>
 233 information provided by the Linux kernel.  If you install the
 234 battery-stats package from unstable now, you will be able to get a
 235 graph of the current battery fill level, to get some idea about the
 236 status of the battery.  The source package build and work just fine in
 237 Debian testing and stable (and probably oldstable too, but I have not
 238 tested).  The default graph you get for that system look like this:</p>
 239
 240 <p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2016-03-15-battery-stats-graph-example.png" width="70%" align="center"></p>
 241
 242 <p>My plans for the future is to merge my old scripts into the
 243 battery-stats package, as my old scripts collected a lot more details
 244 about the battery.  The scripts are merged into the upstream
 245 battery-stats git repository already, but I am not convinced they work
 246 yet, as I changed a lot of paths along the way.  Will have to test a
 247 bit more before I make a new release.</p>
 248
 249 <p>I will also consider changing the file format slightly, as I
 250 suspect the way I combine several values into one field might make it
 251 impossible to know the type of the value when using it for processing
 252 and graphing.</p>
 253
 254 <p>If you would like I would like to keep an close eye on your laptop
 255 battery, check out the battery-stats package in
 256 <a href="https://tracker.debian.org/pkg/battery-stats">Debian</a> and
 257 on
 258 <a href="https://github.com/petterreinholdtsen/battery-stats">github</a>.
 259 I would love some help to improve the system further.</p>
