Raspberry Pi Model B+

Learn to program, control robots or just stream music using this tiny computer.

The Raspberry Pi Model B+ is, like previous models, a tiny computer built for hobbyists, students and anyone who wants to learn more about how computers and computer programs work.

Comparing to its predecessor – the model B , the B+ has a microSD slot (instead of a full-size SD version) and a combined audio/video port (instead of separate stereo sound and composite video connectors). These changes were necessary to make room for its 40-pin GPIO (General Purpose Input/Output) connector that’s designed to connect and control other devices. You can still connect equipment designed for the B’s 26-pin connector, but the extra pins let you hook up even more sensors, lights and motors. It also has four (up from two) USB ports.

Has Shellshock made the internet unsafe?

A new security vulnerability affecting more computers than the Heartbleed bug allows hackers to steal your information from banks, routers and security cameras.

For the second time this year, security experts have discovered a widespread flaw that places the safety of the internet – and the personal information you store on it – in doubt.

The latest vulnerability is called Shellshock, and it affects more computers than Heartbleed – a flaw discovered in April that let hackers extract passwords from hundreds of thousands of the world’s most popular websites.
