Sander Striker
Session(s): Opening Plenary - WE0 - State of the Feather by Sander Striker, President of The Apache Software Foundation – Wednesday - 9:00

Sander Striker is the President of the Apache Software Foundation. He has been active in the ASF since 2000. He has contributed to projects ranging from the Apache Portable Runtime (APR), The HTTP Server Project to Subversion.

Cliff Stoll
Session: Keynote – Wednesday - 9:30

Cliff Stoll's PhD is in planetary astronomy, specializing in radiative transfer in Jovian atmospheres. But he's best known for tracking down a ring of computer hackers who broke into military computers during the mid 1980's. His best selling book, "The Cuckoo's Egg", is now the classic computer spy book.

During the 1990's, frustrated by a constant stream of vapid promises for computers and the Internet, Stoll saw a vast difference between the utopia painted by computer hucksters and the mundane reality of the Internet. From these observations grew his books, "Silicon Snake Oil" and "High Tech Heretic: Why Computers Don't Belong in Schools".

Cliff now makes glass Klein Bottles—mathematical shapes which approximate a class of 4-dimensional, one-sided objects. He's written on the history of computing in Scientific American, and has recently taught physics to 8th graders. He lives in Oakland California with one smiling wife, two tree-climbing kids, three hungry cats, and four wary rats.

From 1993-2003, he worked at the American Association for the Advancement of Science in the Science and Human Rights Program. His most recent work is an estimate of the total deaths in Peru, 1980-2000, conducted on behalf of the Peruvian Truth and Reconciliation Commission.

Patrick has received several awards. This year on April 13, the Electronic Frontier Foundation presented him with their Pioneer Award. In August 2002, the Social Statistics Section of the American Statistical Association gave him a Special Achievement Award. In June 2004, the Association for Computing Machinery (ACM) gave Patrick the Eugene Lawler Award for Humanitarian Contributions within Computer Science and Informatics.

Patrick is currently involved in HRDAG projects in Sierra Leone, Chad, Sri Lanka, East Timor, Colombia, and others.

Howard Tayler, creator of Schlock Mercenary
Session: Keynote - Friday - 11:30

Howard Tayler is a full-time cartoonist who has web-servers to thank for his livelihood. His comic strip, Schlock Mercenary, has appeared online every day since June 12, 2000, and schlockmercenary.com now serves up over 6 million pages a month to over 180,000 unique IPs. He has one book in print, Schlock Mercenary: Under New Management, and a second book coming in November of 2006.

Howard worked for Novell, Inc. for eleven years (1993-2004), during which time he did end-user technical support, large account support, on-site technical consulting, and eventually product management—all for the same set of products. For his last two years at Novell he led the company's product management efforts surrounding their collaboration offerings. He flew to Nuremberg in late 2003 to negotiate some of the finer points of Novell's acquisition of SuSE. In September of 2004 he resigned his position to become a full-time cartoonist.

From 1995 through 2000 Howard moonlighted as an independent record producer. He stepped out of that role about $25,000 poorer, and at least a little bit wiser. He has found cartooning to be more rewarding on several levels.

He hopes that at ApacheCon he can make you laugh while he makes you think. Supposedly that gets more blood flowing to your brain.

Howard lives in Orem, Utah with his wife and four children.
