Deep Thunder for Rio
Rio de Janeiro suffered catastrophic mudslides in 2010 that left at least 100 people dead. The Mayor vowed that such a disaster should never happen again and put his faith in technology to ensure his vow. The forecasting Deep Thunder project, successfully employed in a number of cities, has been rolled out in Rio de Janeiro. It allows for better and more targeted weather forecasts. With the Brazil World Cup approaching, Rio is hoping for a solid defence. Colin Grant talks to Ulisses Mello, Director of IBM research in Brazil, about how big computing is deployed to guard against deadly mudslides.

Hacked: NodeCopters
More than 500 people recently attended Hacked at the O2 Arena in London - a two-day hacking event where attendees learn, build and share a wide variety of computer code-controlled applications. One of the projects available for people to work on was NodeCopter – flying quadcopters that can be controlled by pre-programmed code. Freelance software developer Andrew Nesbitt introduced one of his NodeCopters to Click’s Jen Whyntie.
