Here are a few assorted photos from OSCON this year.

At the center of the Expo Hall was an interview booth.

People waiting outside the main event hall.

This photo does not do the main hall justice. This is the center third of the room. Off the sides are other equivalent sized rooms with their own big screens.

Powell's ran a small book store with all books 30% off.

Alcohol was served the evening Google catered.

The main Expo Hall had a large chess board.
