“Art Post-Internet” was an exhibition curated by Karen Archey and Robin Peckham for the Ullens Center for Contemporary Art in Beijing in spring 2014. This is the specially designed pdf catalogue whose with the front page is created each time with the IP and quite approximated location of the user. It includes tentatively definition of “post-internet” by Cory Arcangel, Simon Denny, and Bunny Rogers, art critics Ben Davis and Paddy Johnson, academics Mark Tribe and Esther Choi, and museum professionals Christiane Paul, Raffael Dörig, Jamillah James, Ben Vickers, Omar Kholeif and Gene McHugh.
20:03:02 Encryption Optics.
At the Optical Fiber Communications Conference and Exhibit will be unveiled this week an encryption of information based on optical fibers, and their properties 'chaotic communications'. Jia-ming Liu, professor of electrical engineering at UCLA in Los Angeles (USA), in fact he tried to send part of a laser beam of photodetectors that produce an electrical signal feedback to power the laser. This circuit behaves erratically, a little 'as the feedback of the acoustic amplifiers and Liu noted how carefully choosing two laser beams can be build two nonlinear circuits (chaotic) whose feedback is identical. For which synchronizing two lasers in different cities, it can send a signal encrypted in this way through optical fibers without any interception can decode it, as has been experienced, at a speed of 2.5 Gbps.
