"The meeting of these guys was definitely the best bang since the big one."

--- Encyclopedia Galactica


Jörg Heitkötter,

was born in 1965 in Recklinghausen, a small but beautiful 750 year old town at the northern rim of the Ruhrgebiet, Germany's coal mining and steel belt. He was educated at Hittorf-Gymnasium, Recklinghausen, Ruhruniversität Bochum (RUB) and Universität Dortmund (UNIDO), where he read theoretical medicine, psychology, biology, philosophy and (for whatever reason) computer sciences.

He volunteered as a RA in the Biomathematics Research Group from 1987 to 1989, at the former ``Max-Planck-Institute for Nutrition Physiology,'' in Dortmund (since March 1, 1993 renamed to ``MPI for Molecular Physiology''), and spent 3 years at the ``Systems Analysis Research Group,'' at the Department of Computer Science of UniDO, where he wrote a particularly unsuccesful thesis on LEARNING CLASSIFIER SYSTEMs. In 1995, after 22 semesters, he finally gave up trying to break Chris Langton's semester record, and dropped out of the academic circus. Amazingly, he's the R&D and Security manager of UUNET Deutschland GmbH, currently working on various interesting things in parallel. You may visit his homepage for a mostly complete list at http://alife.santafe.edu/~joke/ or http://surf.de.uu.net/people/joke

His electronic publications range from a voluntary job as senior editor of the FAQ in Usenet's comp.ai.genetic newsgroup, entitled The Hitch- Hiker's Guide to Evolutionary Computation, over many other projects he helped bootstrapping, for example Howard Gutowitz' FAQ on Cellular Automata, available on USENET via comp.theory.cell-automata ,to about a dozen of so- called ``multimediagrams'' written in HTML, the language that builds the World-Wide Web. The most useful ones being ENCORE, the Evolutionary Computation Repository Network that today, after several years of weekend hacking, is accessible world-wide. And the latest additions: Zooland, the definite collection of pointers to ARTIFICIAL LIFE resources on the 'net.

With Adam Gaffin, a former senior newspaper reporter from Middlesex News, Boston, MA, who is now with Networks World, he edited the most read book on Internet, that was launched by a joined venture of Mitch Kapor's Electronic Frontier Foundation (EFF) and the Apple Computer Library, initially called Big Dummy's Guide to the Internet it was later renamed to EFF's (Extended) Guide to the Internet: A round trip through Global Networks, Life in Cyberspace, and Everything... http://www.eff.org/

Since a very special event, he has severe problems to take life seriously, and consequently started signing everything with ``-joke'', while developing a liquid fixation on all flavours of whiskey. He continues to write short stories, novels and works on a diary-like lyrics collection of questionable content, entitled A Pocketful of Eloquence, which recently was remaned to Heartland, and published on the web as: http://surf.de.uu.net/heartland/

He likes Mickey Rourke's movies (especially Rumblefish and Barfly), Edmund Spenser's medieval poetry, the music of QUEEN, KANSAS, and MARILLION, McDonald's Hamburgers, diving into the analysis of complex systems of any kind, (but prefers the long-legged ones) and the books by Erasmus of Rotterdam, Robert Sheckley, Alexei Panshin, and, you name it, Douglas Adams.

Due to circumstances he lead a life on the edge, until he finally found the perfect match, which has changed many things drammatically: he is not single anymore, and now has his first child (he definitely knows of); on 28 January 2000 Daniel Tobias H. jumped into this world. He even got married on November 5th 1999. If you like this kind of stuff, have a look at the wedding pictures at http://surf.de.uu.net/people/joke/wedding/

Well, so far so good. He is still known to reject job offers that come bundled with Porsches and still doesn't own a BMW Z3 roadster, for he recently purchased a red 1996 Ford Probe Medici, enjoying life at 230 kph, while listening to the formidable 1975 KANSAS song ``Born On Wings Of Steel.''

He still doesn't live in Surrey, but in Dortmund in a knight's castle, which was build in the 16th century and rebuild in the early 90ies. The building with its tower, park and pond is known as Rittergut ``Haus Sölde''.


Nothing really worth listing here.

David Beasley,

was born in London, England in 1961. He was educated at Southampton University where he read (for good reasons) Electronic Engineering.

After spending several years at sea, he went to the Department of Computing Mathematics of the University of Wales, Cardiff, where he studied ARTIFICIAL INTELLIGENCE for a year. He then went on to write a thesis on GAs applied to Digital Signal Processing, and tried to break Joke's publications record.

Since a very special event, he has taken over writing this FAQ, and consequently started signing everything with ``The FAQmaster'' (He's had severe problems taking life seriously for some time before that, however.) He likes Woody Allen's movies, English clothing of medieval times, especially Marks and Spencer, hates McDonald's Hamburgers, but occasionally dives into the analysis of complex systems of any kind, (but prefers those with pedals and handlebars) and the books by (of course) Douglas Adams.

He is not married, has no children, and also also doesn't live in Surrey.

He spent several years working for a (mostly interesting) software company, Praxis in Bath, England. He left after it became clear that the new owners, Deloitte and Touche, had no interest in software engineering. He now works for ingenta, a company which provides on-line access to learned publications and other on-line services to academic users around the world. This includes the long- established BIDS reference services. ingenta ( http://www.ingenta.com/ ) are based at Bath University, England.

"And all our yesterdays have lighted fools the way to dusty death;
out, out brief candle; life's but a walking shadow;
a poor player that struts and frets his hour upon the stage;
and then is heared no more;
it is a tale; told by an idiot,
full of sound and fury,
signifying nothing."

--- Shakespeare, Macbeth
