On Monday, June 25th, Raph Levien will join us to present Lessons from Advogato. Raph, Advogato's founder, will give us insights into attack-resistant trust metrics and the other mechanisms used to build the website's user community.

Like all sessions of the Open Source Developers @ Google Speaker Series, Raph's presentation will be open to the public. Doors open at 6:30 PM at our Mountain View campus; guests should plan to sign in at Building 43 reception upon arrival. Refreshments will be served and all are welcome and encouraged to attend. Raph's presentation will also be taped and published along with all of the public Google Tech Talks.

For those of you who were unable to attend our last session, you can watch the video of Bob Lee's recent presentation Java on Guice: Dependency Injection the Java Way.
