  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 bug #818649 against pm-utils.  I
  67 managed to work around it by adding an udev rule to call the collector
  68 script every time the power connector is connected and disconnected.
  69 With this fix in place it was finally time to make a new release of
  70 the package, and get it into Debian.</p>
  71
  72 <p>If you are interested in how your laptop battery is doing, please
  73 check out the
  74 <a href="https://tracker.debian.org/pkg/battery-stats">battery-stats</a>
  75 in Debian unstable, or rebuild it on Jessie to get it working on
  76 Debian stable. :) The upstream source is available from
  77 <a href="https://github.com/petterreinholdtsen/battery-stats">github</a>.
  78 As always, patches are very welcome.</p>

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

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