Klaus Marquardt is platform program manager at Dräger Medical in Lübeck, Germany.
Klaus's software development experience covers life-support systems, international projects, frameworks and product lines, and agility in regulated environments. He has documented a series of diagnoses and therapies on software systems that stem from his interest in the mutual influences of technology, humans, processes, and organization - these can be found at
http://www.sustainable-architecture.eu. Furthermore, he enjoys writing patterns, running conference sessions that explore new ground, and living and working beyond software.
Michael Hunger has been passionate about many aspects of software development even before he received his Master of CS.
He is particularly interested in the people, software craftsmanship, languages and improving code. While he likes coaching and in-project development as an independent (jexp) for small and mid-sized customers, he really enjoys the numerous other projects in his life. His family with three kids, a longtime obsession for a text based multi user dungeon (MUD), reading books whenever possible, running his coffee shop called "buchbar" (book-bar) and a workshop for printing on things are the one side. The other side is filled with learning and working with new programming languages whenever possible, listening to IT podcasts (esp. Software Engineering Radio), working on exciting and ambitious projects like qi4j.org, creating DSLs (jequel, squill and xmldsl.org), tons of refactoring and contributing to and reviewing books in progress (Martin Fowlers DSL-book, Software Apprenticeship Patterns, 97 Things Every Programmer Should Know, and many more). Sometimes he even finds time to do a bigger project with some friends like test.secretari.us, an open source e-mail based time management application.
