Dress in your best 1960s attire for a grand-opening party this Saturday at the Kleinrock Internet Heritage Site on the UCLA campus. The site is like Colonial Williamsburg for nerds (or is that redundant?), with a historical reconstruction of the lab where the Internet was born in 1969. The party starts at 1:00 pm. There will be drinks, snacks, and Internet pioneers to gawk at. They are not joking about the period costumes.
