Computing in the net of possibilities. (Phys.org) -- Scientists at the Max Planck Institute for Dynamics and Self-Organization in Göttingen have developed an entirely new principle for information processing. The complex network computer now stands as an alternative to the other possibilities in data processing - such as the conventional computer or the quantum computer. The fundamental requirement is a system, for instance a laser, with oscillating elements that can interact with one another.
The researchers were able to demonstrate that the characteristic dynamics of such a system can be cleverly harnessed to perform the full range of logical operations. The complex network computer can even perform some tasks, such as the coarse sorting of numbers, considerably faster than conventional computers. Furthermore, the researchers have managed to take a first step in programming a robot according to the new principle. A computer is much more than simply hardware. All logical operations can be performed in one network.
Discover your inner Pirate. For the last two years Offensive Security has been taking the live training market by storm with its flagship course, Pentesting with BackTrack. We are very excited to announce that the next PWB live training will be held in an exotic location the Caribbean island of St. Kitts and Nevis. St. Kitts is a tiny island set in the middle of glass-like beautiful waters, perfect beaches and the pain and suffering that only PWB can bring. By day you will be taught some of the most advanced and hands-on penetration testing methods by the creators of BackTrack. After 5 days of torment in paradise we end the course with a Caribbean-style cruise. 20 Hackers, crystal clear waters and enough rum to choke a blue whale – what more can you ask for? Discover your inner pirate – join us for Pentesting With BackTrack St.
The course is scheduled for Nov 28 2011 – Dec 2 2011. Mining social networks: Untangling the social web. TELECOMS operators naturally prize mobile-phone subscribers who spend a lot, but some thriftier customers, it turns out, are actually more valuable. Known as “influencers”, these subscribers frequently persuade their friends, family and colleagues to follow them when they switch to a rival operator. The trick, then, is to identify such trendsetting subscribers and keep them on board with special discounts and promotions.
People at the top of the office or social pecking order often receive quick callbacks, do not worry about calling other people late at night and tend to get more calls at times when social events are most often organised, such as Friday afternoons. Influential customers also reveal their clout by making long calls, while the calls they receive are generally short. Companies can spot these influencers, and work out all sorts of other things about their customers, by crunching vast quantities of calling data with sophisticated “network analysis” software.
