Hackers blind quantum cryptographers

Lasers crack commercial encryption systems, leaving no trace.

Quantum hackers have performed the first ‘invisible’ attack on two commercial quantum cryptographic systems. By using lasers on the systems — which use quantum states of light to encrypt information for transmission — they have fully cracked their encryption keys, yet left no trace of the hack.

  • The Aesthetics and Beauty of Knowledge

    Shih was the opposite of facts and raw information; shih was the elegance of knowledge, the insight and skill to organize knowledge into meaningful patterns. As an artist chooses colours or light to make her pictures, a master of shih chooses textures of knowledge – various ideas, myths, abstractions, and theories – to create a way of seeing the world. The aesthetics and beauty of knowledge – this was shih.

    – David Zindell, The Broken God, 1993

  • Geek Attitude

    The attitude thing is about flexibility, portability, creativity, sociability and jamming (ran out of suitable “ity” words!). It’s about improvising – in the practical and musical senses of the word; not getting tangled in boundaries and the “right” way to do things.
    Definitely the only way to travel.
