If you're not familiar with the PARC Forum, then be glad you happened to read this post.
Most people know PARC as the place that famously turned Steve Jobs on to graphical user interfaces in the 1970s. You may not know that since about the same time PARC has been hosting talks by a diverse range of speakers, which are free of charge and open to the public. Since I've been attending, two of my favorite talks have spanned the spectrum from Leslie Lamport pondering the nature of computation to Sue Conley from the Cow Girl Creamery discussing her efforts in pioneering the artisan cheese movement in America (yes, with a tasting). If you live in the Bay Area, it's definitely worth keeping an eye on the schedule. Tomorrow's Forum is "A Behind the Scene Look at Google Maps Street View" by Luc Vincent an Engineering Director at Google.
If you're not in the Bay Area, you're still in luck. PARC recently started streaming the talks on Jutin.tv. Go to http://www.justin.tv/parcinc on Thursdays at 4:00pm pacific time to tune in to the live presentation. Most past Forums are archived and available at http://www.parc.com/events/forum.html.
PARC Forums are typically held every Thursday at 4:00pm (they are occasionally hosted on Wednesdays and Fridays). Forums take place in the George E. Pake Auditorium located near the upper parking lot.
