Graham Glass graduated from the University of Southampton, England, with a Bachelor's degree in Computer Science and Mathematics. He immigrated to the United States and obtained his Master's degree in Computer Science from the University of Texas at Dallas. He then worked as a UNIX/C systems analyst and became heavily involved with research in neural networks and parallel distributed processing. He later taught at the University of Texas at Dallas, covering a wide variety of courses including UNIX, C, assembly language, programming languages, C++, and Smalltalk. He co-founded ObjectSpace, which specialized in object-oriented training, consulting, and products. He then founded The Mind Electric, which produced a Java web services platform called Glue and a platform for shared SOA infrastructure called Fabric. The Mind Electric was acquired by webMethods, where Graham is now the Chief Technology Officer. In his spare time, he reads, runs, swims, cycles, dives, skis, travels, and maintains a blog.

King Ables earned his Bachelor's degree in Computer Science from the University of Texas at Austin in 1982. He has been a UNIX user, developer, systems administrator, or consultant since 1979 and a Linux user since late in the last century. He has worked in academia, at small startup companies, and in large corporations, and is currently an independent consultant specializing in IT services and network security. He has developed UNIX and Linux product software and systems tools, delivered support and training services, and written product documentation and training materials. He has authored or co-authored two books on UNIX, written many magazine articles on various UNIX topics, and is a co-inventor of an e-commerce privacy mechanism that was awarded a software patent. His professional interests include networking, security, and privacy, but he likes hiking, mountain biking, and skiing just a bit more.
