		<title>CQRS &amp; the architecture coming along</title>
		<description><![CDATA[In my previous blog post I made a proposal in the footnotes to rename the architecture that often comes along with the pattern CQRS. I thought of a &#8220;Circular Architecture&#8221; to clearly contrast it with a &#8220;Layered Architecture&#8221;. After a brief discussion with Greg Young and Alistair Cockburn about this I decided to take this idea under [...]]]></description>

		<title>CQRS &amp;&amp; Validation &amp;&amp; Business Rules</title>
		<description><![CDATA[Validation and business rules within a CQRS architecture [1][2] continue to raise issues for those who first hear of it. Three specific questions are often asked: how does the validation of commands work, how can one enforce business rules on large collections (state) and how does the enforcement of business rules on multiple aggregates work? Hopefully I [...]]]></description>

		<title>TDD &amp; DbC @ DotRT</title>
		<description><![CDATA[Last wednesday there was another Devnology event: the developers of the round table met at.. a rectangular one. Despite the out-of-place table, it was a very good meeting in any way that matters. I couldn&#8217;t shake of the feeling that the program didn&#8217;t fully work out as planned, but everybody was completely cool with it [...]]]></description>

		<title>Python and the Google AppEngine at the CodeFest</title>
		<description><![CDATA[On the first of april the first Devnology CodeFest took place. An interesting group of 16 enthousiastic developers gathered at the Sogyo farm to make an implementation of the Game of Life, the famous cellulair automaton, devised by Conway. 
My goal for that night was to make an implementation of the Game of Life in [...]]]></description>

		<title>Seminar Fixed price + Agile + DDD</title>
		<description><![CDATA[During the evening of March the 17th, Sogyo will organize another technical seminar. In this one, Sogyo employees Rick van der Arend (that&#8217;s me!) and André Boonzaaijer will explain how we can handle the wishes of many of our customers to get an agile software project, in a domain driven way, but with a planned [...]]]></description>

		<title>David vs. Goliath</title>
		<description><![CDATA[In this post I will give my answer to the question where innovation takes place: in big or in smaller (ict-) companies? An all-or-nothing answer doesn&#8217;t seem feasible to me, because we all know examples of big as well as smaller companies that are innovative. But I still think it might be interesting enough to [...]]]></description>

		<title>Domain exploration &#8211; really</title>
		<description><![CDATA[The last few week have been quite exhilirating! Two weeks of really exploring a domain, getting to know a new client&#8217;s business and language. I have always liked going through such a phase and one does not always get the chance to do something like that for two whole weeks at the client&#8217;s site. 
Preparation [...]]]></description>

		<title>Xrump</title>
		<description><![CDATA[ After a few years of experience with agile software projects, I have read the Agile manifesto again and afterwards read more specifically about the details of XP and Scrum, the most well-known agile methodologies. It occurred to me that from both &#8217;sides&#8217; a way of mixing the two is actively being sought. It seems like a [...]]]></description>

		<title>The learning curve</title>
		<description><![CDATA[The shame! Two months of inactivity on this blog&#8230; the reason? A steep learning curve.
I have been diving deep into the .NET framework, at the sub-CLR level. What all the versions mean, how they interact. How assemblies and modules look like at the byte level. What actually happens when methods are called and types are loaded, [...]]]></description>

		<title>PDC: Azure and Oslo</title>
		<description><![CDATA[Lots of new stuff at the PDC that is going on right now.. but Windows Azure (&#8216;Windows in the clouds&#8217;) &#38; Oslo generate the most buzz in the developers community. Windows Azure is of course Microsoft&#8217;s response to the c2 and s3 engines of Amazon, Google&#8217;s AppEngine and a few others. Interesting, but it will take [...]]]></description>
