  1. Free book downloads might not boost sales, but it does not hurt you either–at least, as long as your book is technical;
  2. Fourth and final draft of GPLv3 is released;
  3. Diamonds as quantum computer memory building blocks:

    Surmounting several distinct hurdles to quantum computing, physicists at Harvard University have found that individual carbon-13 atoms in a diamond lattice can be manipulated with extraordinary precision to create stable quantum mechanical memory and a small quantum processor, also known as a quantum register, operating at room temperature. The finding brings the futuristic technology of quantum information systems into the realm of solid-state materials under ordinary conditions.

  4. This one sounds familiar to the story I linked to quite a while agosolar cells that surpass 40% efficiency (via).
