Kevlin Henney is an independent consultant, speaker, writer and trainer. His development interests are in patterns, programming, practice and process. He has contributed to open- and closed-source development, has been a columnist for a number of magazines and sites, including The Register, and has been on far too many committees (it has been said that "a committee is a cul-de-sac down which ideas are lured and then quietly strangled"). He is co-author of A Pattern Language for Distributed Computing and On Patterns and Pattern Languages and editor of 97 Things Every Programmer Should Know. He lives in Bristol and online.
