Undocumented UCLA students stand in line at a graduation ceremony for UCLA "Dreamers", or Dream Act students, at a church near the campus in Los Angeles on Friday. Undocumented youths who came to the United States as children reacted with joy to an Obama administration rule change on Friday that could spare them deportation, although opponents slammed it as amnesty.

UCLA computer scientists are pictured in the birthplace of the Internet at the original location of the first ARPANET node, at 3420 Boelter Hall in UCLA in this undated photograph provided by UCLA. UCLA professor Leonard Kleinrock and his team used the Interface Message Processor, IMP, the packet-switching node used to interconnect participant networks to the ARPANET to send the first message, the letters LO to Standford Research Institute on October 29, 1969. The UCLA Department of Computer Science and Henry Samueli School of Engineering and Applied Science have collaborated in creating the Kleinrock Internet Heritage Site and Archive (KIHSA) with the center recreating the lab at its original site in 3420 Boelter Hall, moving the IMP back to the room from which that first message was sent.The recreated lab will open October 29 with a reunion of the computer scientists responsible for the first message.

Distinguished Professor of Computer Science at UCLA Leonard Kleinrock is seen in the birthplace of the Internet, at 3420 Boelter Hall in UCLA, July 27, 2011. Kleinrock developed the mathematical theory of packet networks, the technology underpinning the Internet which was used in the transmission of the first message, the letters LO, to Stanford Research Institute on October 29, 1969.
