Web Component Development with Zope 3 (eBook)

The author's computer programming started out as a hobby and became a profession very quickly. He has been a web developer for many years, having opened his own business during high school already. He started his first Zope project almost half a decade ago and has successfully used Zope in innumerable applications since. A few years ago, when the rewrite of Zope was initiated, he became a developer of Zope 3. He has been continually contributing to Zope and related projects itself since. Currently he is studying Physics at the Dresden University of Technology, while continuing the Internet business.
