Speakers

One of the best reasons to attend the O'Reilly Open Source Convention is the unprecedented gathering of top-notch presenters, leaders, and experts. Core developers, unique users, and visionaries share their knowledge with you to help you solve your computing or programming challenges. You won't find a gathering like this at any other convention.

Our speaker list is growing daily. Please check back regularly to see who we have lined up for you.

Ron Hitchens
Ron Hitchens is a California-based computer consultant and educator whose career dates back to the disco era. His first exposure to computers was operating mainframes in the Air Force. His first programming language was COBOL, learned from a friend's borrowed textbook. Since that time Hitchens has used just about every computer system and programming language you can imagine: from 6502 assembler to XSLT.

Hitchens spent much of the 1980s at the University of Texas at Austin, as student and staffer, where he burrowed deep into the Unix kernel and assisted with many interesting research projects.

Hitchens spent the next several years doing kernel work for clients such as IBM and Unisys. He has also developed and taught professional development courses for the same clientele.

Following a brief flirtation with C++, Hitchens fell in love with Java and has spent the last several years employing server-side Java technologies to build Web applications for clients ranging from start-ups to Fortune 500 companies. Hitchens is Founder and President of Ronsoft Technologies.

Hitchens is also the author of O'Reilly's Java NIO.

Hitchens lives in California with his wife and co-pilot, Karen, and a dog named Boomer. When Ron isn't working (hah!) he and Karen enjoy snorkeling, bicycling and walking the dog.
