  • "The Open Cloud Consortium (OCC) is a member driven organization that:

    Supports the development of standards for cloud computing and frameworks for interoperating between clouds;
    develops benchmarks for cloud computing;
    supports reference implementations for cloud computing, preferably open source reference implementations;
    manages a testbed for cloud computing called the Open Cloud Testbed;
    sponsors workshops and other events related to cloud computing."

  • "The dashed circles above represent "forbidden regions" in which one of the angles would be obtuse. As Lindgren and Cassidy and Lord showed, eight triangles is best possible, and there exist alternate solutions with any even number of triangles larger than eight.

    Recently, John Tromp added a new twist to the problem by asking on sci.math how to make the angles as acute as possible. For the eight-triangle solution, he found a placement of the vertices in which the maximum angle is only about 85 degrees, and asked if more triangles would achieve even better angles."
