- <description><p>Around three years ago, I created
-<a href="http://packages.qa.debian.org/isenkram">the isenkram
-system</a> to get a more practical solution in Debian for handing
-hardware related packages. A GUI system in the isenkram package will
-present a pop-up dialog when some hardware dongle supported by
-relevant packages in Debian is inserted into the machine. The same
-lookup mechanism to detect packages is available as command line
-tools in the isenkram-cli package. In addition to mapping hardware,
-it will also map kernel firmware files to packages and make it easy to
-install needed firmware packages automatically. The key for this
-system to work is a good way to map hardware to packages, in other
-words, allow packages to announce what hardware they will work
-with.</p>
-
-<p>I started by providing data files in the isenkram source, and
-adding code to download the latest version of these data files at run
-time, to ensure every user had the most up to date mapping available.
-I also added support for storing the mapping in the Packages file in
-the apt repositories, but did not push this approach because while I
-was trying to figure out how to best store hardware/package mappings,
-<a href="http://www.freedesktop.org/software/appstream/docs/">the
-appstream system</a> was announced. I got in touch and suggested to
-add the hardware mapping into that data set to be able to use
-appstream as a data source, and this was accepted at least for the
-Debian version of appstream.</p>
-
-<p>A few days ago using appstream in Debian for this became possible,
-and today I uploaded a new version 0.20 of isenkram adding support for
-appstream as a data source for mapping hardware to packages. The only
-package so far using appstream to announce its hardware support is my
-pymissile package. I got help from Matthias Klumpp with figuring out
-how do add the required
-<a href="https://appstream.debian.org/html/sid/main/metainfo/pymissile.html">metadata
-in pymissile</a>. I added a file debian/pymissile.metainfo.xml with
-this content:</p>
-
-<blockquote><pre>
-&lt;?xml version="1.0" encoding="UTF-8"?&gt;
-&lt;component&gt;
- &lt;id&gt;pymissile&lt;/id&gt;
- &lt;metadata_license&gt;MIT&lt;/metadata_license&gt;
- &lt;name&gt;pymissile&lt;/name&gt;
- &lt;summary&gt;Control original Striker USB Missile Launcher&lt;/summary&gt;
- &lt;description&gt;
- &lt;p&gt;
- Pymissile provides a curses interface to control an original
- Marks and Spencer / Striker USB Missile Launcher, as well as a
- motion control script to allow a webcamera to control the
- launcher.
- &lt;/p&gt;
- &lt;/description&gt;
- &lt;provides&gt;
- &lt;modalias&gt;usb:v1130p0202d*&lt;/modalias&gt;
- &lt;/provides&gt;
-&lt;/component&gt;
-</pre></blockquote>
-
-<p>The key for isenkram is the component/provides/modalias value,
-which is a glob style match rule for hardware specific strings
-(modalias strings) provided by the Linux kernel. In this case, it
-will map to all USB devices with vendor code 1130 and product code
-0202.</p>
-
-<p>Note, it is important that the license of all the metadata files
-are compatible to have permissions to aggregate them into archive wide
-appstream files. Matthias suggested to use MIT or BSD licenses for
-these files. A challenge is figuring out a good id for the data, as
-it is supposed to be globally unique and shared across distributions
-(in other words, best to coordinate with upstream what to use). But
-it can be changed later or, so we went with the package name as
-upstream for this project is dormant.</p>
-
-<p>To get the metadata file installed in the correct location for the
-mirror update scripts to pick it up and include its content the
-appstream data source, the file must be installed in the binary
-package under /usr/share/appdata/. I did this by adding the following
-line to debian/pymissile.install:</p>
-
-<blockquote><pre>
-debian/pymissile.metainfo.xml usr/share/appdata
-</pre></blockquote>
-
-<p>With that in place, the command line tool isenkram-lookup will list
-all packages useful on the current computer automatically, and the GUI
-pop-up handler will propose to install the package not already
-installed if a hardware dongle is inserted into the machine in
-question.</p>
-
-<p>Details of the modalias field in appstream is available from the
-<a href="https://wiki.debian.org/DEP-11">DEP-11</a> proposal.</p>
-
-<p>To locate the modalias values of all hardware present in a machine,
-try running this command on the command line:</p>
-
-<blockquote><pre>
-cat $(find /sys/devices/|grep modalias)
-</pre></blockquote>

+ <description><p>So, Cambridge Analytica is getting some well deserved criticism for
+(mis)using information it got from Facebook about 50 million people,
+mostly in the USA. What I find a bit surprising, is how little
+criticism Facebook is getting for handing the information over to
+Cambridge Analytica and others in the first place. And what about the
+people handing their private and personal information to Facebook?
+And last, but not least, what about the government offices who are
+handing information about the visitors of their web pages to Facebook?
+No-one who looked at the terms of use of Facebook should be surprised
+that information about peoples interests, political views, personal
+lifes and whereabouts would be sold by Facebook.</p>
+
+<p>What I find to be the real scandal is the fact that Facebook is
+selling your personal information, not that one of the buyers used it
+in a way Facebook did not approve when exposed. It is well known that
+Facebook is selling out their users privacy, but a scandal
+nevertheless. Of course the information provided to them by Facebook
+would be misused by one of the parties given access to personal
+information about the millions of Facebook users. Collected
+information will be misused sooner or later. The only way to avoid
+such misuse, is to not collect the information in the first place. If
+you do not want Facebook to hand out information about yourself for
+the use and misuse of its customers, do not give Facebook the
+information.</p>
+
+<p>Personally, I would recommend to completely remove your Facebook
+account, and take back some control of your personal information.
+<a href="https://www.theguardian.com/technology/2018/mar/19/how-to-protect-your-facebook-privacy-or-delete-yourself-completely">According
+to The Guardian</a>, it is a bit hard to find out how to request
+account removal (and not just 'disabling'). You need to
+<a href="https://www.facebook.com/help/224562897555674?helpref=faq_content">visit
+a specific Facebook page</a> and click on 'let us know' on that page
+to get to <a href="https://www.facebook.com/help/delete_account">the
+real account deletion screen</a>. Perhaps something to consider? I
+would not trust the information to really be deleted (who knows,
+perhaps NSA, GCHQ and FRA already got a copy), but it might reduce the
+exposure a bit.</p>
+
+<p>If you want to learn more about the capabilities of Cambridge
+Analytica, I recommend to see the video recording of the one hour talk
+Paul-Olivier Dehaye gave to <a href="">NUUG</a> last april about
+<a href="https://www.nuug.no/aktiviteter/20170404-big-data-psychometric/">
+Data collection, psychometric profiling and their impact on
+politics</a>.</p>
+
+<p>And if you want to communicate with your friends and loved ones,
+use some end-to-end encrypted method like
+<a href="https://www.signal.org/">Signal</a> or
+<a href="https://ring.cx/">Ring</a>, and stop sharing your private
+messages with strangers like Facebook and Google.</p>
