The Old New Thing

Raymond Chen: Raymond has been involved in the evolution of Windows for more than 25 years. In 2003, he began a Web site known as The Old New Thing which has grown in popularity far beyond his wildest imagination, a development which still gives him the heebie-jeebies. The Web site spawned a book, coincidentally also titled The Old New Thing (Addison Wesley 2007). He currently appears regularly on MSDN Channel 9’s One Dev Minute channel in the One Dev Question video series.
