+ <div class="date"> 7th December 2019</div>
+ <div class="body"><p>When asked to accept terms of use and privacy policies that state
+it will to remove rights I otherwise had or accept unreasonable terms
+undermining my privacy, I choose away the service. I simply do not
+have the conscience to accept terms I have no indention of upholding.
+But how are the system and service providers to know how many people
+they scared away? Normally I just quietly walk away. But today, I
+tried a new approach. I sent the following email (removing the
+specifics, as I am not out to take the specific service in question)
+to the service provider I decided to not use, to at least give them
+one data point on how many users are unhappy with their terms:</p>
+
+<blockquote>

+<br>Subject: When terms of use turn users away
+<br>To: [contact@some.site]
+<br>Date: Sat, 07 Dec 2019 16:30:56 +0100
+
+<p>Dear [Site Owner],</p>
+
+<p>I was eager to test the system, as it seemed like a fun and
+interesting application of [some] technology, but after reading the
+terms of use and privacy policy on <URL:
+https://www.[some.site]/terms-of-use > and <URL:
+https://www.[some.site]/privacy-policy > I want you to know that I
+decided to turn away. There were several provisions in the terms and
+policy turning me off, but the final term that convinced me was being
+asked to sign away my right to reverse engineer.</p>
+
+<p>--
+<br>Happy hacking
+<br>Petter Reinholdtsen</p>
+</blockquote>
+
+<p>I do not expect much to come out of it, but sharing it here in case
+others want to give something similar a try too. If companies
+discover their terms scare away enough people, perhaps they will be
+improved...</p>

+ <div class="date">25th November 2019</div>
+ <div class="body"><p>Four years ago, I did a back of the envelope calculation on
+<a href="http://people.skolelinux.org/pere/blog/What_would_it_cost_to_store_all_phone_calls_in_Norway_.html">how
+much it would cost to store audio recordings of all the phone calls in
+Norway</a>, and came up with NOK 2.1 million / EUR 250 000 for the
+year 2013. It is time to repeat the calculation using updated
+numbers. The calculation is based on how much data storage is needed
+for each minute of audio, how many minutes all the calls in Norway
+sums up to, multiplied by the cost of data storage.</p>
+
+<p>The number of phone call minutes for 2018 was fetched from
+<a href="https://ekomstatistikken.nkom.no/">the NKOM statistics
+site</a>, and for 2018, land line calls are listed as 434 238 000
+minutes, while mobile phone calls are listed with 7 542 006 000
+minutes. The total number of minutes is thus 7 976 244 000. For
+simplicity, I decided to ignore any advantages in audio compression the
+last four years, and continue to assume 60 Kbytes/min as the last
+time.</p>
+
+<p>Storage prices still varies a lot, but as last time, I decide to
+take a reasonable big and cheap hard drive, and double its price to
+include the surrounding costs into account. A 10 TB disk cost less
+than 4500 NOK / 450 EUR these days, and doubling it give 9000 NOK per
+10 TB.</p>
+
+<p>So, with the parameters in place, lets update the old table
+estimating cost for calls in a given year:</p>
+
+<table border="1">
+<tr><th>Year</th><th>Call minutes</th><th>Size</th><th>Price in NOK / EUR</th></tr>
+<tr><td>2005</td><td align="right">24 000 000 000</td><td align="right">1.3 PiB</td><td align="right">1 170 000 / 117 000</td></tr>
+
+<tr><td>2012</td><td align="right">18 000 000 000</td><td align="right">1.0 PiB</td><td align="right">900 000 / 90 000</td></tr>
+
+<tr><td>2013</td><td align="right">17 000 000 000</td><td align="right">950 TiB</td><td align="right">855 000 / 85 500</td></tr>
+
+<tr><td>2018</td><td align="right">7 976 244 000</td><td align="right">445 TiB</td><td align="right">401 100 / 40 110</td></tr>
+</table>
+
+<p>Both the cost of storage and the number of phone call minutes have
+dropped since the last time, bringing the cost down to a level where I
+guess even small organizations can afford to store the audio recording
+from every phone call taken in a year in Norway. Of course, this is
+just the cost of buying the storage equipment. Maintenance, need to
+be included as well, but the volume of a single year is about a single
+rack of hard drives, so it is not much more than I could fit in my own
+home. Wonder how much the electricity bill would raise if I had that
+kind of storage? I doubt it would be more than a few tens of thousand
+NOK per year.</p>

- <div class="date"> 2nd June 2019</div>
- <div class="body"><p>A while back a college and friend from Debian and the Skolelinux /
-Debian Edu project approached me, asking if I knew someone that might
-be interested in helping out with a technology project he was running
-as a teacher at <a href="https://www.ecolefrancodanoise.dk/">L'école
-franco-danoise</a> - the Danish-French school and kindergarden. The
-kids were building robots, rovers. The story behind it is to build a
-rover for use
-<a href="http://blog.ecolefrancodanoise.dk/first-week-on-the-dark-side">on
-the dark side of the moon</a>, and remote control it. As travel cost
-was a bit high for the final destination, and they wanted to test the
-concept first, he was looking for volunteers to host a rover for the
-kids to control in a foreign country. I ended up volunteering as a
-host, and last week the rover arrived. It took a while to arrive
-after <a href="http://blog.ecolefrancodanoise.dk/model-moms">it was
-built and shipped</a>, because of customs confusion. Luckily we were
-able fix it quickly with help from my colleges at work.</p>
-
-<p>This is what it looked like when the rover arrived. Note the cute
-eyes looking up on me from the wrapping</p>

-<p style="text-align:left">Once the robot arrived, we needed to track
-down batteries and figure out how to build custom firmware for it with
-the appropriate wifi settings. I asked a friend if I could get two
-18650 batteries from his pile of Tesla batteries (he had them from the
-wrack of a crashed Tesla), so now the rover is running on Tesla
-batteries.</p>
-
-<p>Building
-<a href="https://gitlab.com/ecolefrancodanoise/arduino-efd/">the rover
-firmware</a> proved a bit harder, as the code did not work out of the
-box with the Arduino IDE package in Debian Buster. I suspect this is
-due to a unsolved
-<a href="https://github.com/arduino/Arduino/pull/2703"> license problem
-with arduino</a> blocking Debian from upgrading to the latest version.
-In the end we gave up debugging why the IDE failed to find the
-required libraries, and ended up using the Arduino Makefile from the
-<a href="https://tracker.debian.org/pkg/arduino-mk">arduino-mk Debian
-package</a> instead. Unfortunately the camera library is missing from
-the Arduino environment in Debian, so we disabled the camera support
-for the first firmware build, to get something up and running. With
-this reduced firmware, the robot could be controlled via the
-controller server, driving around and measuring distance using its
-internal acoustic sensor.</p>
-
-<p>Next, With some help from my friend in Denmark, which checked in the
-camera library into the gitlab repository for me to use, we were able
-to build a new and more complete version of the firmware, and the
-robot is now up and running. This is what the "commander" web page
-look like after taking a measurement and a snapshot:</p>
