The MSDN Camp vs. The Raymond Chen Camp
A few months ago in Joel Spolsky's How Microsoft Lost the API War he wrote
There are two opposing forces inside Microsoft, which I will refer to, somewhat tongue-in-cheek, as The Raymond Chen Camp and The MSDN Magazine Camp.
The Raymond Chen Camp believes in making things easy for developers by making it easy to write once and run anywhere (well, on any Windows box). The MSDN Magazine Camp believes in making things easy for developers by giving them really powerful chunks of code which they can leverage, if they are willing to pay the price of incredibly complicated deployment and installation headaches, not to mention the huge learning curve. The Raymond Chen camp is all about consolidation. Please, don't make things any worse, let's just keep making what we already have still work. The MSDN Magazine Camp needs to keep churning out new gigantic pieces of technology that nobody can keep up with.
When I first read the above paragraphs I disagreed with them because I was in denial. But as the months have passed and I've looked at various decisions my team has made in recent years I see the pattern. The patterns repeats itself in the actions of other product teams and divisions at Microsoft. I know realize this is an unfortunate and poisonous aspect of Microsoft's culture which doesn't work in the best interest of our customers. A few months ago I found some advice given to Ward Cunningham on joining Microsoft which read
Take a running start and don't look back
- Recognize that your wonderful inventiveness is the most valuable thing you will own in a culture that values its employees solely by their latest contributions. In a spartan culture like this, you will rise quickly.
- Keep spewing ideas, even when those ideas are repeatedly misunderstood, implemented poorly, and excised from products for reasons that have nothing to do with the quality of the idea. When you give up on communicating your new ideas, you will just go insane waiting to vest.
The Microsoft culture is about creating the newest, latest greatest thing that 'changes the world' not improving what is already out there and working for customers. When I read various Microsoft blogs and MSDN headlines about how even though we've made paradigm shifts in developer technologies in the recent years we aren't satisfied and want to introduce radically new and different technologies all over again. This bothers me. I hate the fact that 'you have to rewrite a lot of your code' is a common answer to questions a customer might ask about how to leverage new or upcoming functionality in a developer technology.
Our team [and myself directly] has gone through a process of rethinking a number of decisions we made in this light. Up until very recently we were planning to ship the System.Xml.XPath.XPathDocument class as a replacement for the System.Xml.XmlDocument class. One of the driving reasons for doing this was XPath and XSLT performance. The mismatch between the DOM data model and that of XPath meant that XPath queries or XSLT transformations over the XmlDocument would never be as fast as XPathDocument. Another reason we were doing this was that since the XmlDocument is not an interface based design there isn't a way for people who implement their own XML document-like classes to plug-in to our world. So we decided to de-emphasize (but not deprecate) the XmlDocument by not adding any new functionality or performance improvements to it and focused all our energy on XPathDocument.
The problem was that the XPathDocument had a radically different programming model than the XmlDocument meaning that anyone who'd written code using the XmlDocument against our v1.0/v1.1 bits would have to radically rewrite their code to get performance improvements and new features. Additionally any developers migrating to the .NET Framework from native code (MSXML) or from the Java world would already be familiar with the XML DOM API but not the cursor-based model used by the XPathDocument. This was really an untenable situation. For this reason we've reverted the XPathDocument to what it was in v1.1 while new functionality and perf improvements will be made to the XmlDocument. Similarly we will keep the new and improved
XPathEditableNavigator XPathNavigator class which will be the API for programming against XML data sources where one wants to abstract away what the underlying store actually is. We've shown the power of this model with examples such as the ObjectXPathNavigator and the DataSetNavigator.
It's good to be back in the Raymond Chen camp.
