Unless you've traded your guitar strings for an axe-shaped MIDI controller, tuning your guitar is probably one of those chores you've just learned to deal with. It's hardly the bane of any guitarist's existence, but sometimes it seems like there could just be a faster, more brainless way to get your instrument ready to jam. Turns out, there is.
Roadie positions itself as the next generation of guitar tuners. Think of it like a modern String Master, a device that fits snugly over your instrument's tuning pegs and does the hard part for you. Paired with a companion smartphone app, Roadie listens your guitar's strings and turns its gears until the instrument is on key. We dropped by the team's table at Haxlr8r, and the process was dead easy, quickly tuning a demo guitar without breaking a string. In fact, it's designed not to -- by comparing a string's elasticity with its frequency, the device can actually warn you when your guitar's wires are about to break. Not a bad trick, particularly for guitarists (like this editor) that aren't completely sure when their instrument was last restrung. The device's Kickstarter page has already more than half of its $60,000 goal, and has a little over a month left to get the rest. Looking for a way to chip in (and to avoid guitar maintenance)? Check out the source link below; Roadie tuners start at $79.

Remember that Apple / PrimeSense deal that was rumored to be going down in July? It may have just gone through: according to Israeli news source Calcalist, Cupertino acquired the motion sensing technology firm for $345 million this weekend. If true, it could hint at future Apple products with natural, motion controlled interfaces, integrating the same kind of technology that PrimeSense used to help Microsoft build the first Kinect. In a statement to the TheNextWeb, PrimeSense refers to the report as a "recycled rumor," saying only that it "does not comment on what any of our partners, customers or potential customers are doing." According to the report, Apple is hounding after the motion sensing tech to improve Apple TV, noting that the original deal was delayed due to legal issues. Hungry for more?

Despite recent successes in the field, creating a quantum computer is really hard. For one thing quantum bits in a super positioned state (or qubits, the basic unit of data for quantum computing) have a hard time surviving at room temperature. Typically, these superposition states last for only a few seconds, but in a recent experiment at Simon Fraser University in Burnaby , researchers were able to keep a quantum system alive for a full 39 minutes.
"These lifetimes are at least ten times longer than those measured in previous experiments," explained Stephanie Simmons from the University of Oxford's Department of Materials. "Having such robust, as well as long-lived, qubits could prove very helpful for anyone trying to build a quantum computer." Even so, they aren't particularly active ones - all of the qubits in the experiment shared the same quantum state. To perform actual calculations (and thus build a functioning quantum computer), a system would need to put multiple qubtis in different quantum states. Sound complicated? It sure is, but it's a significant step forward to building the ultrafast computing platforms of tomorrow. Eager to learn more? Check out the official press release at the source link below.
