			<content:encoded><![CDATA[<p>Bad blogger me, late as usual.<br />
On Thursday I got back from a longer trip to <a href="http://cern.ch/">CERN</a>, Geneva. The purpose of the trip was to sit shift for the HLT subsystem in <a href="http://en.wikipedia.org/wiki/A_Large_Ion_Collider_Experiment">ALICE</a>, on behalf of the University of Bergen. While not a prerequisite for completion, its was part of my <a href="http://www.jonnor.com/tag/hopfe/">senior project</a>.</p>
<p>Due to the whole volcano ash thing, we had to take the train from Tønsberg, Norway to Geneva, Switzerland(!!). Actually we didn&#8217;t have to, but we wanted to go, and after 4 days of &#8220;ash clouds, maybe there will be a flight, maybe there wont&#8221; we decided to just get there on our own.<br />
The trip turned out a bit less smooth because the ordinary night trains from Copenhagen to Basel were full, so we had to wait 8 hours in Copenhagen and switch between several small regional trains in Denmark in the middle of the night. But hey, we got to see Copenhagen also <img src='http://www.jonnor.com/wp/wp-includes/images/smilies/icon_wink.gif' alt=';)' class='wp-smiley' /> </p>
<p>The mainline news coverage of the volcano ash business has been all but sickening, but the following little comic made me laugh hard. Especially because of the supposed-to-look-icelandish language used:</p>
<p><img title="pondus.no: Fun with bankrupt countries whos vulcanos are distupting international air travel" src="http://pondus.no/Global/Twitpic/island.jpg" alt="'Put 30 billion euro in the garbage can infront of the icelandish embassy tonight, and we will turn off the vulcano! Don't call the police!'" /></p>
<p class="wp-caption-text">&#8216;Put 30 billion euro in the garbage can in front of the Icelandic embassy tonight, and we will turn off the volcano! Don&#8217;t call the police!&#8217;</p>
<p>Down at CERN, most of the shifts were pretty uneventful as there was seldom &#8220;stable beams&#8221;. The beam refers to the particles being accelerated (in the <a href="http://en.wikipedia.org/wiki/LHC">LHC</a> in ALICEs case), and stable means that collisions are happening in a controlled manner so that you can actually start data-taking.<br />
So, when you&#8217;re not taking data, sitting shifts mostly means noting down problems that occur with your subsystem, and possibly notifying the on-call expect if deemed serious enough. Actually, being a shifter on HLT should be like that all the time, as it is supposed to be a completely autonomous system in this aspect.<br />
I got to work a bit on my <a href="http://www.jonnor.com/tag/hopfe/">senior project</a>, a bit on MyPaint, a bit on other things, but didn&#8217;t really get to be as productive as I would have liked. Especially on the night-shift, I found it hard to do any serious work. Strange, as I often have my most productive times after midnight when at home.</p>
<p>One thing I regret the most is packing too much clothes, and not bringing a camera. Even if we didn&#8217;t really do a lot of very exciting stuff, it still would have been nice to have pictures; Capturing the moment, binding the state of mind at that instant to something physical, for easier retrieval at a later time.</p>
