Eternal September, the rise of amateur culture exhibition at Aksioma, curated by Valentina Tanni. From internet folklore to the deja vu “on the screen” an exploration of “amateur culture” quickly corroding certainties. http://www.aksioma.org/eternal.september/index.html
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.
