Linux Solves Rubics Cube

The fastest time for a human to solve a Rubik’s cube is 4.9 seconds. This robot can do it in 1.019 seconds.

Software engineers Jay Flatland and Paul Rose built this piece of kit, which uses four webcams to determine the state of the jumbled cube. The information is then fed into a computer, using the Kociemba Rubik’s cube-solving algorithm to work out a set of moves to solve the puzzle. A set of small motors mounted in a 3D-printed frame then swivel the, presumably extremely well-oiled, Rubik’s cube.

The previous quickest time for a robot to solve the cube is 2.39 seconds, so it looks like this could be a record breaker; however, they’re still waiting for official verification from Guinness World Records.

Pretty impressive. Although some super slow-motion footage wouldn’t go amiss.

Everything You Need to Know About The Ubuntu Tablet

View post on

The ‘BQ Aquaris M10 Ubuntu Edition’ (to give the model its full name) is a high-resolution 10-inch tablet —and then some.

Introducing the Keybase filesystem

Every file you write in there is signed. There’s no manual signing process, no taring or gzipping, no detached sigs. Instead, everything in this folder appears as plaintext files on everyone’s computers. You can even open /keybase/public/yourname in your Finder or Explorer and drag things in.

Why The Internet of Things and the Cloud Should Break Up

For IoT developers, the cloud is like beer in a college dorm: a cold one is around every corner you turn and … beer just becomes a constant of academic life.
