			<content:encoded><![CDATA[<p>Sometimes when I export MySQL to files, I end up having one huge query on one line. It can be quite annoying! I&#8217;d rather want it on several lines; in that way it easier to just copy out a fragment of the query. And it also seems that some editors handle several lines better than one huge. Well, in this case my line looked like this:</p>

			<content:encoded><![CDATA[<p>I finally got access to a Google Wave sandbox account, making it possible to start experimenting. The first thing I made was a Latex robot. By adding the robot, it&#8217;s possible to write Latex in Waves. Afterwards, simply by putting Latex between two $&#8217;s:</p>

<div class="wp_syntax"><div class="code"><pre class="latex" style="font-family:monospace;"><span style="color: #8020E0; font-weight: normal;">$$<span style="color: #800000; font-weight: normal;">\lim</span>_<span style="color: #E02020; ">{</span><span style="color: #2020C0; font-weight: normal;">n <span style="color: #800000; font-weight: normal;">\to</span> <span style="color: #800000; font-weight: normal;">\infty</span></span><span style="color: #E02020; ">}</span> <span style="color: #800000; font-weight: normal;">\frac</span><span style="color: #E02020; ">{</span><span style="color: #2020C0; font-weight: normal;">1</span><span style="color: #E02020; ">}{</span><span style="color: #2020C0; font-weight: normal;">n</span><span style="color: #E02020; ">}</span> = 0$</span>$</pre></div></div>

<p>Watexy then changes the Wave and inserts the Latex as an image instead of the text.</p>
<p>You can try it yourself by adding watexy [this-funny-curly-a] appspot.com to your Wave-conversations. <a href="http://www.scienco.org/wp-content/watexy-v009.zip">You can download the source here.</a></p>
<p>There&#8217;s still a quite big bug: It&#8217;s only the first Latex-image that gets substituted correctly. The following gets inserted some positions wrong, and the deletion of the text isn&#8217;t correct neither. But the images itself are correct, only the substitution isn&#8217;t working properly. But I&#8217;m working on that!</p>
<p>The more technical part: the robot is written in Python, hence using the Google Wave Python API. It&#8217;s the first time I&#8217;ve tried that (thought it was a good possibility to learn it). The robot basically works by getting triggered when a new blip is submitted. Then it searches for Latex-code in that and substitutes it with pictures. Although the code is quite simple, it shows some very basic concepts on how to alter/change the contents of Waves on-the-fly (deleting text and inserting images, but it could be other things as well) with robots. The Latex-source-to-image is done by the <a title="http://www.forkosh.dreamhost.com/source_mathtex.html#webservice" href="http://www.forkosh.dreamhost.com/source_mathtex.html#webservice">http://www.forkosh.dreamhost.com/source_mathtex.html#webservice</a> service.</p>
<p>The core Python comprising the robot is this:</p>

<div class="wp_syntax"><div class="code"><pre class="python" style="font-family:monospace;"><span style="color: #808080; font-style: italic;"># Python reference:</span>
<span style="color: #808080; font-style: italic;"># http://wave-robot-python-client.googlecode.com/svn/trunk/pydocs/index.html</span>
&nbsp;
<span style="color: #808080; font-style: italic;"># Shortcut to the important OpBasedDocument</span>
<span style="color: #808080; font-style: italic;"># http://wave-robot-python-client.googlecode.com/svn/trunk/pydocs/waveapi.ops.OpBasedDocument-class.html</span>
&nbsp;
<span style="color: #483d8b;">&quot;&quot;&quot; 
Known bugs:
- From (and including) the second Latex-fragment, the positioning gets wrong
  &gt; Probably the document needs some kind of updatering
  &gt; Even though it's a bit strange since the re matches all the Latex correctly

  <span style="color: #483d8b;">&quot;&quot;&quot; 
  Only replace one Latex-fragment at a time, because replaceing one fragment
  changes the text positions in the rest. That's why re.finditer isn't used.

			<content:encoded><![CDATA[<p>This is a tutorial about how to use Ubuntu Server 8.04 as dom0 (host) for Xen, i.e. how to install Xen on Ubuntu Server. In a later post I&#8217;ll show how to install domUs (guests). The whole setup is done with a rather complex disk configuration using both raid 1 (mirroring) and LVM. It requires some knowledge about Xen (e.g. I&#8217;ll not try to convince you to use Xen &#8211; I assume it&#8217;s already your plan and you had read of all the advantages it gives you <img src='http://www.scienco.org/wp-includes/images/smilies/icon_smile.gif' alt=':-)' class='wp-smiley' /> ). <a href="http://www.scienco.org/2008/xen-on-ubuntu-server-804-hardy-heron-with-complex-disk-setup/#more-58" class="more-link">(more&#8230;)</a></p>

			<content:encoded><![CDATA[<p>Yesterday I wrote an entry regarding ESXi. More precisely I described how to try VMware ESXi in VMware Workstation. My argument was on one side to try ESXi out (I&#8217;ve never installed nor tried it) and on the other side investigate whether it was a product I would use.</p>
