Discovery of a "Flat" Atom Hailed as Quantum Computing Breakthrough 205

msw writes to tell us that nanoelectronics researchers have discovered a new molecule that could act as a state-manipulable atom due to its unique shape and properties. "Imagine a tiny arsenic atom embedded in a tiny strip of silicon atoms. An electric current is applied. Something strange arises on the surface -- an exotic molecule. On one end is the spherical submerged arsenic atom; on the other end is an 'artificial' flat atom, seemingly 2D, created as an artifact. The pair form an exotic molecule, which has a shared electron, which can be manipulated to be at either end, or in an intermediate quantum state."

Using AI With GCC to Speed Up Mobile Design 173

Atlasite writes "The WSJ is reporting on a EU project called Milepost aimed at integrating AI inside GCC. The team partners, which include include IBM, the University of Edinburgh and the French research institute, INRIA, announced their preliminary results at the recent GCC Summit, being able to increase the performance of GCC by 10% in just one month's work. GCC Summit paper is provided [PDF]."

Are SSDs Really More Power Efficient? 222

Bakasama writes "Tom's Hardware compared the power performance of several available SSD cards with a Rotating HDD that was chosen specifically for its poor power efficiency. The results seem to fly in the face of current wisdom. 'Flash-based solid state drives (SSDs) are considered to be the future of performance hard drives, and everyone seems to be jumping on the bandwagon. We are no exception, as we have been publishing many articles on flash-based SSDs during the last few months, emphasizing the performance gains and the potential power savings brought by flash memory. And there is nothing wrong with this, since SLC flash SSDs easily outperform conventional hard drives today (SLC = single level cell). However, we have discovered that the power savings aren't there: in fact, battery runtimes actually decrease if you use a flash SSD.'"

Supplies of Rare Earth Elements Exhausted By 2017 958

tomhudson writes "While we bemoan the current oil crisis, I ran across an editorial that led me to research a more immediate threat. Ramped-up production of flat-panel displays means the material to make them will be 'extinct' by 2017. This goes for other electronics as well. Quoting: 'The element gallium is in very short supply and the world may well run out of it in just a few years. Indium is threatened too, says Armin Reller, a materials chemist at Germany's University of Augsburg. He estimates that our planet's stock of indium will last no more than another decade. All the hafnium will be gone by 2017 also, and another twenty years will see the extinction of zinc. Even copper is an endangered item, since worldwide demand for it is likely to exceed available supplies by the end of the present century.' More links at the journal entry."

Some people have a great ambition: to build something that will last, at least until they've finished building it.
