    If you're interested in how much detail the engineers at Mountain View pay to every element of Google's search business, check this out. This is footage of the Quality Launch Review, a meeting that takes place every week on Thursdays. Amit Singhal assembles a room full of engineers to delve into "losses," the company term for when a search query goes awry, and turn them into "wins." This week, the team examined error-correction in searches that are over ten words long, and how best to resolve it. It may not be the most exciting thing you'll ever see, but it's a fascinating insight into the effort that begins every time you don't find what you're looking for.

  • Yale Physicists develop quantum computing error correction, are a qubit pleased with themselves

    We're big fans of quantum computing, and hopefully it's about to get a lot more reliable. Researchers at Yale have demonstrated quantum error correction in a solid state system for the first time. Quantum bits were created from "artificial" atoms using superconducting circuits, these qubits are then given either of the typical bit states of "1" or "0," or the quantum state of both simultaneously. The researchers developed a technique that identifies each qubit's initial state, so any erroneous changes can be reversed on the fly. Until now, errors have been a barrier in quantum computing, accumulating and ultimately causing computational failure. A reliable means of fixing these state changes is essential to developing a computer with an exponential speed-up, and fully realizing the quantum dream. The team at Yale hopes that this research might mean its platform of superconducting circuits becomes the one upon which quantum computing is ultimately built. We, on the other hand, just want our parallel universe.

  • Micron embeds error correction in flash memory chips, calls it ClearNAND

    Solid state storage is fantastic stuff, durable and lightning-quick, but it's got its fair share of quirks -- bits fail, pages fill up, and cells deteriorate over time. Typically, the onus is on a beefy controller to take care of your drive and make sure it lasts a good long while (which is why brand names like SandForce can make or break an SSD) but it looks like Micron is planning to usurp some of that responsibility with its new ClearNAND chips. Simply put, each ClearNAND memory module has a built-in 24-bit error correction engine, so your drive's host controller doesn't have to shoulder that load, and can focus on the good stuff -- like getting your data delivered at speeds that would obliterate traditional hard drives. Micron says the new chips are available right now in 25nm sizes. Want a more technical rundown? Hit up our more coverage link to hear what this might mean for the error-prone future of the medium. PR after the break.
