These are published on his bi-monthly "The Java(tm) Specialists' Newsletter" (http://www.javaspecialists.co.za). It is not for the uninitiated :-) Heinz received a PhD in Computer Science from the University of CapeTown. He loves living in South Africa as it is both beautiful and interesting. Professionally, Heinz survives by writing Java code, insulting, ahem, consulting, and presenting courses on Java and Design Patterns.
Rick Kitts has been making a living writing software for a little while. He's started a company or two, worked at bigger companies, but mostly at startups. Constantly on the look out for things to help him build better systems he's a bit of a tool and process slut, though he can't bring himself to try C# or get serious about UML. Go figure. He's convinced being invited to have a weblog on Artima is the result of some glitch in the matrix. He's keeping quiet about it though.

Angelika Langer works as an independent freelance trainer, mentor, and consultant with a course curriculum of her own and conducts seminars in Europe and Northern America. Her current work is backed by more than a decade of experience as a software engineer working for German and US companies, among them sevaral years in telecommunications and later in compiler construction at Siemens and 1.5 year in library development at Rogue Wave Software. Compiler construction got her involved into the standardization of C++ and in 1993 she joined the standards committee. When Java appeared in 1995 she immediately pounced on the new language. Since then she is truly bilingual, using both languages in parallel, and inevitably mixing up the syntax at times, naturally looking forward to adding a third curly brace language to the skill set, just to increase the confusion. In 1997 she decided that 13 years of sitting in front of a computer day in and day out were enough (at least for her taste) and she shifted her focus to training, coaching, and mentoring.

Most who've heard of Van Simmons before will remember him in his former role as President of VNP Software. Since 1990, Van has usually made a living architecting, designing, writing and generally being frustrated with large systems for Wall Street firms. Originally he hacked his way about these in Objective-C on the old NeXT platform, but starting in 1996, he realized that he was flogging a dead horse and transferred his allegiance to the (then) immature Java platform. These days, Van is an employee of a firm with a lot of numbers to crunch, so he's spending his days trying to figure out how to get an hours worth of computation done in a minute of elapsed time. Venting, musing and guffawing on this topic is what he plans to write about.

Gregg Wonderly graduated from Oklahoma State University in 1988 with an MS in COMSCI. His areas of concentration include Operating Systems and Languages. His first job was at the AT&T Bell Labs facilities in Naperville IL working on software retrofit for the 5ESS switch. He designed a procedure control language in the era of the development of Java with similar motivations that the Oak and then Java language development was driven by. Language design is still at the top of his list, but his focus tends to be on application languges layered on top of programming languages such as Java. Some just consider this API design, but there really is more to it! Gregg now works for Cyte Technologies Inc., where he does software engineering and design related to distributed systems in highly available environments.
