+ <description><p>Yesterday, I
+<a href="http://www.hungry.com/~pere/blog/First_prototype_ready_making_hardware_easier_to_use_in_Debian.html">asked
+for testers</a> for my prototype for making Debian better at handling
+pluggable hardware devices, which I
+<a href="http://www.hungry.com/~pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html">set
+out to create</a> earlier this month. Several valuable testers showed
+up, and caused me to really want to to open up the development to more
+people. But before I did this, I want to come up with a sensible name
+for this project. Today I finally decided on a new name, and I have
+renamed the project from hw-support-handler to this new name. In the
+process, I moved the source to git and made it available as a
+<a href="http://anonscm.debian.org/gitweb/?p=collab-maint/isenkram.git">collab-maint</a>
+repository in Debian. The new name? It is <strong>Isenkram</strong>.
+To fetch and build the latest version of the source, use</p>
+
+<pre>
+git clone http://anonscm.debian.org/git/collab-maint/isenkram.git
+cd isenkram && git-buildpackage -us -uc
+</pre>
+
+<p>I have not yet adjusted all files to use the new name yet. If you
+want to hack on the source or improve the package, please go ahead.
+But please talk to me first on IRC or via email before you do major
+changes, to make sure we do not step on each others toes. :)</p>
+
+<p>If you wonder what 'isenkram' is, it is a Norwegian word for iron
+stuff, typically meaning tools, nails, screws, etc. Typical hardware
+stuff, in other words. I've been told it is the Norwegian variant of
+the German word eisenkram, for those that are familiar with that
+word.</p>
+
+<p><strong>Update 2013-01-26</strong>: Added -us -us to build
+instructions, to avoid confusing people with an error from the signing
+process.</p>
+
+<p><strong>Update 2013-01-27</strong>: Switch to HTTP URL for the git
+clone argument to avoid the need for authentication.</p>

+ <description><p>Early this month I set out to try to
+<a href="http://www.hungry.com/~pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html">improve
+the Debian support for pluggable hardware devices</a>. Now my
+prototype is working, and it is ready for a larger audience. To test
+it, fetch the
+<a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/">source
+from the Debian Edu subversion repository</a>, build and install the
+package. You might have to log out and in again activate the
+autostart script.</p>
+
+<p>The design is simple:</p>
+
+<ul>
+
+<li>Add desktop entry in /usr/share/autostart/ causing a program
+hw-support-handlerd to start when the user log in.</li>
+
+<li>This program listen for kernel events about new hardware (directly
+from the kernel like udev does), not using HAL dbus events as I
+initially did.</li>
+
+<li>When new hardware is inserted, look up the hardware modalias in
+the APT database, a database
+<a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/modaliases?view=markup">available
+via HTTP</a> and a database available as part of the package.</li>
+
+<li>If a package is mapped to the hardware in question, the package
+isn't installed yet and this is the first time the hardware was
+plugged in, show a desktop notification suggesting to install the
+package or packages.</li>
+
+<li>If the user click on the 'install package now' button, ask
+aptdaemon via the PackageKit API to install the requrired package.</li>
+
+<li>aptdaemon ask for root password or sudo password, and install the
+package while showing progress information in a window.</li>
+
+</ul>
+
+<p>I still need to come up with a better name for the system. Here
+are some screen shots showing the prototype in action. First the
+notification, then the password request, and finally the request to
+approve all the dependencies. Sorry for the Norwegian Bokmål GUI.</p>
+

+<br><img src="http://www.hungry.com/~pere/blog/images/2013-01-21-hw-support-5-installing-details.png" width="70%"></p>
+
+<p>The prototype still need to be improved with longer timeouts, but
+is already useful. The database of hardware to package mappings also
+need more work. It is currently compatible with the Ubuntu way of
+storing such information in the package control file, but could be
+changed to use other formats instead or in addition to the current
+method. I've dropped the use of discover for this mapping, as the
+modalias approach is more flexible and easier to use on Linux as long
+as the Linux kernel expose its modalias strings directly.</p>
+
+<p><strong>Update 2013-01-21 16:50</strong>: Due to popular demand,
+here is the command required to check out and build the source: Use
+'<tt>svn checkout
+svn://svn.debian.org/debian-edu/trunk/src/hw-support-handler/; cd
+hw-support-handler; debuild</tt>'. If you lack debuild, install the
+devscripts package.</p>
+
+<p><strong>Update 2013-01-23 12:00</strong>: The project is now
+renamed to Isenkram and the source moved from the Debian Edu
+subversion repository to a Debian collab-maint git repository. See
+<a href="http://www.hungry.com/~pere/blog/Welcome_to_the_world__Isenkram_.html">build
+instructions</a> for details.</p>
