Registration is now open for the 23rd annual ACM SIGPLAN conference on Object-Oriented Programming, Systems, Languages, and Applications.

What's in store? Here are some highlights of keynotes to entertain, inform, and challenge you:

• Mark Lehner who works on discovering the story that the Giza pyramids and plateau have to tell.
• Lucy Suchman studies the way people work together and with technological artifacts. She will challenge us to rethink our ideas on what information systems are and how they should be designed. As you might expect, Lucy's talk is one that I'm hugely looking forward to!
• Janos Sztipanovits works on model integrated computing and embedded systems at Vanderbilt University and the Institute for Software Integrated Systems in Nashville.

And, of course, there is more. Expect food for thought from Rebecca Wirfs-Brock, Mark Jason Dominus and David Gries.

Aside from the keynote programme, we've also got the research papers, world-class tutorials, plus the workshops, panels, practitioner reports, posters, demonstrations, the Onward! program and much, much more addressing a wide range of important new and well-established topics.

See you in Nashville!
