			<content:encoded><![CDATA[<p>My favourite scripting language is <a href="http://python.org">Python</a> and there are quite few interesting projects done:</p>
<ul>
<li><a href="http://pymol.org/">PyMol</a> - molecular visualization system on an open source foundation</li>
<li><a href="http://dirac.cnrs-orleans.fr/MMTK/">MMTK</a> is an Open Source program library for molecular simulation applications.</li>
<li><a href="http://pyquante.sourceforge.net/">PyQuante</a>  is an open-source suite of programs for developing quantum chemistry methods.</li>
<li><a href="http://cclib.sourceforge.net/">cclib</a>  is an open source library, written in Python, for parsing and interpreting the results of computational chemistry packages.</li>
</ul>
<p><a href="http://pyquante.sourceforge.net/">PyQuante</a> and <a href="http://dirac.cnrs-orleans.fr/MMTK/">MMTK</a> are most suitable for the start of method framework.</p>
<p>Action plan:</p>
<ol>
<li>Bootstrap PyQuante.  It works out of the box, but some of its tests do not pass - have to check this out.</li>
<li>Do the same for MMTK.</li>
<li>Implement at least some gradients and force constants functionality for PyQuante and make sure geometry of simple molecules optimize to something reasonable</li>
<li>Dissect <a href="http://openmopac.net/">popular</a> and not-so-popular QCh software packages to work within the framework above.</li>
<li>Compile a basis set and a control set of molecules to control and optimize precision of different modeling methods</li>
<li>Sum up, review and work out a new plan.</li>
</ol>

			<content:encoded><![CDATA[<p>Lately there wasn&#8217;t much things to write about.</p>
<p>When you scale your business, there are plenty of lessons and observations.  But theren&#8217;t that much you&#8217;d really like to tell the world about, and even less you can because of various NDA and confidentiality issues.</p>
<p>Nevertheless, looks finally (knock-knock-knock) <a href="http://42coffeecups.com">42 Coffee Cups</a> can run successfuly without my 24&#215;7 attention and I can devote my time to other interests that waited for too long.</p>
<p>Once of them is computational chemistry.</p>
<p>I&#8217;ve done some scientific work using computational chemistry modeling in 1990-1997 and still believe that it <em>is</em> the necessary element of nearly every future technology in health, energy, chemistry, IT, food, etc for the next 50+ yrs.</p>
<p>So what I see needs to be done for the Tool to appear&#8230;</p>
<ol>
<li>Robust modeling methods to be used of various scales
<ul>
<li><em>ab initio</em> methods with high precision for small systems, </li>
<li>semiempirics for systems around 1K atoms and more, </li>
<li>MM approximations for systems with 10K-100K+ atoms</li>
<li>continuous body approximations for larger systems </li>
</ul>
</li>
<li>Interfaces between methods listed above, so I can start model on macro level and drill down in most interesting features to discover what happens on atomic level</li>
<li>Strong feedback from experimental methods:
<ul>
<li>compute what could be measured, preferably immediately</li>
<li>measure what could be computed</li>
</ul>
</li>
<li>Visualization, analytics and search systems to harvest the data, both computed and experimental</li>
</ol>
<p>I still do not know how this should be enveloped for business purposes - I&#8217;m too far in software and away from product development cycles in large companies.  Guess this would sort out on go.</p>
<p>The cornerstone is the modeling method and scripting glue, so that what I&#8217;d start with.</p>

			<content:encoded><![CDATA[<p>Now reviewing tools and services to quickly sketch and prototype user interfaces.</p>
<p>I&#8217;ve been advised to check <a href="http://www.balsamiq.com/products/mockups">balsamiq mockups</a>.  What puts me off is:</p>
<ul>
<li>either a desktop version or a limited list of tools it could integrate into; no <a href="trac.edgewall.org/">trac</a> integration</li>
<li>steep price tag, esp for an non-desktop version</li>
<li>nearly free-hand drawing, I&#8217;d like to have something closer to an html</li>
</ul>
<p>There is also a <a href="http://www.twiddla.com/">twiddla</a>, which offers an excellent teamwork service.  Perhaps I&#8217;ll advise my team to use it to perform quick sketch sessions with clients.</p>
<p>Yet again it offers just a widgetized free-hand drawing.  That means I hardly can integrate it in the <em>development</em> process, only into a communication.</p>
<p>On the other hand, there&#8217;s a simple grid-based css generator at  http://960.gs/  Nice as a component, but too simplistic as a service <img src='http://a.khavr.com/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>
<p>Something like <a href="http://blog.fav.or.it/2008/10/channel-layout-editor-preview/">this editor</a> would be an ideal fit, but they seem to target it only for their own service..</p>
<p>What I&#8217;ve missed?</p>
