- <description><p>It was a surprise to me to learn that project to create a complete
-computer system for schools I've involved in,
-<a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>, was
-being used in India. But apparently it is, and I managed to get an
-interview with one of the friends of the project there, Shirish
-Agarwal.</p>
-
-<p><strong>Who are you, and how do you spend your days?</strong></p>
-
-<p>My name is Shirish Agarwal. Based out of the educational and
-historical city of Pune, from the western state of Maharashtra, India.
-My bread comes from giving training, giving policy tips,
-installations on free software to mom and pop shops in different
-fields from Desktop publishing to retail shops as well as work with
-few software start-ups as well.</p>
-
-<p><strong>How did you get in contact with the Skolelinux / Debian Edu
-project?</strong></p>
-
-<p>It started innocently enough. I have been using Debian for a few
-years and in one local minidebconf / debutsav I was asked if there was
-anything for schools or education. I had worked / played with free
-educational softwares such as Gcompris and Stellarium for my many
-nieces and nephews so researched and found Debian Edu or Skolelinux as
-it was known then. Since then I have started using the various
-education meta-packages provided by the project.</p>
-
-<p><strong>What do you see as the advantages of Skolelinux / Debian
-Edu?</strong></p>
-
-<p>It's closest I have seen where a package full of educational
-software are packed, which are free and open (both literally and
-figuratively). Even if I take the simplest software which is
-gcompris, the number of activities therein are amazing. Another one of
-the softwares that I have liked for a long time is stellarium. Even
-pysycache is cool except for couple of issues I encountered
-<a href="https://bugs.debian.org/781841">#781841</a> and
-<a href="https://bugs.debian.org/781842">#781842</a>.</p>
-
-<p>I prefer software installed on the system over web based solutions,
-as a web site can disappear any time but the software on disk has the
-possibility of a larger life span. Of course with both it's more a
-question if it has enough users who make it fun or sustainable or both
-for the developer per-se.</p>
-
-<p><strong>What do you see as the disadvantages of Skolelinux / Debian
-Edu?</strong></p>
-
-<p>I do see that the Debian Edu team seems to be short-handed and I
-think more efforts should be made to make it popular and ask and take
-help from people and the larger community wherever possible.</p>
-
-<p>I don't see any disadvantage to use Skolelinux apart from the fact
-that most apps. are generic which is good or bad how you see it.
-However, saying that I do acknowledge the fact that the canvas is
-pretty big and there are lot of interesting ideas that could be done
-but for reasons not known not done or if done I don't know about them.
-Let me share some of the ideas (these are more upstream based but
-still) I have had for a long time :</p>
-
-<p>1. Classical maths question of two trains in opposing directions
-each running @x kmph/mph at y distance, when they will meet and how
-far would each travel and similar questions like these.
-
-<p>The computer is a fantastic system where questions like these can
-be drawn, animated and the methodology and answers teased out in
-interactive manner. While sites such as the
-<a href="http://mathforum.org/dr.math/faq/faq.two.trains.html">Ask
-Dr. Math FAQ on The Two Trains problem</a> (as an example or point of
-inspiration) can be used there is lot more that can be done. I dunno
-if there is a free software which does something like this. The idea
-being a blend of objects + animation + interaction which does
-this. The whole interaction could be gamified with points or sounds or
-colourful celebration whenever the user gets even part of the question
-or/and methodology right. That would help reinforce good behaviour.
-This understanding could be used to share/showcase everything from how
-the first wheel came to be, to evolution to how astronomy started,
-psychics and everything in-between.</p>
-
-<p>One specific idea in the train part was having the Linux mascot on
-one train and the BSD or GNU mascot on the other train and they
-meeting somewhere in-between. Characters from blender movies could
-also be used.</p>
-
-<p>2. Loads of crossword-puzzles with reference to subjects: We have
-enormous data sets in Wikipedia and Wikitionary. I don't think it
-should be a big job to design crossword puzzles. Using categories and
-sub-categories it should be doable to have Q&A single word answers
-from the existing data-sets. What would make it easy or hard could be
-the length of the word + existence of many or few vowels depending on
-the user's input.</p>
-
-<p>3. Jigsaw puzzles - We already have a great software called
-palapeli with number of slicers making it pretty interesting. What
-needs to be done is to download large number of public domain and
-copyleft images, tease and use IPTC tags to categorise them into
-nature, history etc. and let it loose. This could turn to be really
-huge collection of images. One source could be taken from
-commons.wikimedia.org, others could be huge collection of royalty-free
-stock photos. Potential is immense.</p>
-
-<p>Apart from this, free software suffers in two directions, we lag
-both in development (of using new features per-se) and maintenance a
-lot. This is more so in educational software as these applications
-need to be timely and the opportunity cost of missing deadlines is
-immense. If we are able to solve issues of funding for development and
-maintenance of such software I don't see any big difficulties. I know
-of few start-ups in and around India who would love to develop and
-maintain such software if funding issues could be solved.</p>
-
-<p><strong>Which free software do you use daily?</strong></p>
-
-<p>That would be huge list. Some of the softwares are obviously apt,
-aptitude, debdelta, leafpad, the shell of course (zsh nowadays),
-quassel for IRC. In games I use shisen-sho while card-games are evenly
-between kpat and Aiselriot. In desktops it's a tie between
-gnome-flashback and mate.</p>
-
-<p><strong>Which strategy do you believe is the right one to use to
-get schools to use free software?</strong></p>
-
-<p>I think it should first start with using specific FOSS apps. in
-whatever environment they are. If it's MS-Windows or Mac so be it.
-Once they are habitual with the apps. and there is buy-in from the
-school management then it could be installed anywhere. Most of the
-people now understand the concept of a repository because of the
-various online stores so it isn't hard to convince on that front.</p>
-
-<p>What is harder is having enough people with technical skills and
-passion to service them. If you get buy-in from one or two teachers
-then ideas like above could also be asked to be done as a project as
-well.</p>
-
-<p>I think where we fall short more than anything is in marketing. For
-instance, Debian has this whole range of fonts in its archive but
-there isn't even a page where all those different fonts in the La
-Ipsum format could be tried out for newcomers.</p>
-
-<p>One of the issues faced constantly in installations is with updates
-and upgrades. People have this myth that each update and upgrade
-means the user interface will / has to change. I have seen this
-innumerable times. That perhaps is one of the reasons which browsers
-like Iceweasel / Firefox change user interfaces so much, not because
-it might be needed or be functional but because people believe that
-changed user interfaces are better. This, can easily be pointed with
-the user interfaces changed with almost every MS-Windows and Mac OS
-releases.</p>
-
-<p>The problems with Debian Edu for deployment are many. The biggest
-is the huge gap between what is taught in schools and what Debian Edu
-is aimed at.
-
-<p>Me and my friends did teach on week-ends in a government school for
-around 2 years, and
-<a href="https://flossexperiences.wordpress.com/2012/10/08/sharings/">gathered
-some experience</a> there. Some of the things we learnt/discovered
-there was :</p>
-
-<ol>
-
- <li>Most of the teachers are very territorial about their subjects
- and they do not want you to teach anything out of the
- portion/syllabus given.</li>
-
- <li>They want any activity on the system in accordance to whatever
- is in the syllabus.</li>
-
- <li>There are huge barriers both with the English language and at
- times with objects or whatever. An example, let's say in gcompris
- you have objects falling down and you have to name them and let's
- say the falling object is a hat or a fedora hat, this would not be
- as recognizable as say a
- <a href="https://en.wikipedia.org/wiki/Puneri_Pagadi">Puneri
- Pagdi</a> so there is need to inject local objects, words wherever
- possible. Especially for word-games there are so many hindi words
- which have become part of english vocabulary (for instance in
- parley), those could be made into a hinglish collection or
- something but that is something for upstream to do.</li>

+ <description><p>Most people seem not to realise that every time they walk around
+with the computerised radio beacon known as a mobile phone their
+position is tracked by the phone company and often stored for a long
+time (like every time a SMS is received or sent). And if their
+computerised radio beacon is capable of running programs (often called
+mobile apps) downloaded from the Internet, these programs are often
+also capable of tracking their location (if the app requested access
+during installation). And when these programs send out information to
+central collection points, the location is often included, unless
+extra care is taken to not send the location. The provided
+information is used by several entities, for good and bad (what is
+good and bad, depend on your point of view). What is certain, is that
+the private sphere and the right to free movement is challenged and
+perhaps even eradicated for those announcing their location this way,
+when they share their whereabouts with private and public
+entities.</p>
+
+<p align="center"><img width="70%" src="http://people.skolelinux.org/pere/blog/images/2016-01-24-nice-creepy-desktop-window.png"></p>
+
+<p>The phone company logs provide a register of locations to check out
+when one want to figure out what the tracked person was doing. It is
+unavailable for most of us, but provided to selected government
+officials, company staff, those illegally buying information from
+unfaithful servants and crackers stealing the information. But the
+public information can be collected and analysed, and a free software
+tool to do so is called
+<a href="http://www.geocreepy.com/">Creepy or Cree.py</a>. I
+discovered it when I read
+<a href="http://www.aftenposten.no/kultur/Slik-kan-du-bli-overvaket-pa-Twitter-og-Instagram-uten-a-ane-det-7787884.html">an
+article about Creepy</a> in the Norwegian newspaper Aftenposten i
+November 2014, and decided to check if it was available in Debian.
+The python program was in Debian, but
+<a href="https://tracker.debian.org/pkg/creepy">the version in
+Debian</a> was completely broken and practically unmaintained. I
+uploaded a new version which did not work quite right, but did not
+have time to fix it then. This Christmas I decided to finally try to
+get Creepy operational in Debian. Now a fixed version is available in
+Debian unstable and testing, and almost all Debian specific patches
+are now included
+<a href="https://github.com/jkakavas/creepy">upstream</a>.</p>
+
+<p>The Creepy program visualises geolocation information fetched from
+Twitter, Instagram, Flickr and Google+, and allow one to get a
+complete picture of every social media message posted recently in a
+given area, or track the movement of a given individual across all
+these services. Earlier it was possible to use the search API of at
+least some of these services without identifying oneself, but these
+days it is impossible. This mean that to use Creepy, you need to
+configure it to log in as yourself on these services, and provide
+information to them about your search interests. This should be taken
+into account when using Creepy, as it will also share information
+about yourself with the services.</p>
+
+<p>The picture above show the twitter messages sent from (or at least
+geotagged with a position from) the city centre of Oslo, the capital
+of Norway. One useful way to use Creepy is to first look at
+information tagged with an area of interest, and next look at all the
+information provided by one or more individuals who was in the area.
+I tested it by checking out which celebrity provide their location in
+twitter messages by checkout out who sent twitter messages near a
+Norwegian TV station, and next could track their position over time,
+making it possible to locate their home and work place, among other
+things. A similar technique have been
+<a href="http://www.buzzfeed.com/maxseddon/does-this-soldiers-instagram-account-prove-russia-is-covertl">used
+to locate Russian soldiers in Ukraine</a>, and it is both a powerful
+tool to discover lying governments, and a useful tool to help people
+understand the value of the private information they provide to the
+public.</p>
+
+<p>The package is not trivial to backport to Debian Stable/Jessie, as
+it depend on several python modules currently missing in Jessie (at
+least python-instagram, python-flickrapi and
+python-requests-toolbelt).</p>
+
+<p>(I have uploaded
+<a href="https://screenshots.debian.net/package/creepy">the image to
+screenshots.debian.net</a> and licensed it under the same terms as the
+Creepy program in Debian.)</p>
