It’s been some time since we last covered Startup Weekend, a series of events that bring a roomful of developers and entrepreneurs together to develop new startups in only 54 hours. When the program originally launched last year, each weekend was geared towards building a single application, of which every participating member was a cofounder. Since then the format has changed – multiple companies are created at each event, and they don’t have to incorporate at the end of the weekend. Here’s a handful of the companies founded at last weekend’s event, which was held in Phoenix.

With so much of our essential data making its way to the cloud, it’s becoming increasingly difficult to quickly make a local backup. Reserve Chute, an open source web app that will be available for use in the next few weeks, will automatically make backups of popular cloud based services including Gmail, Twitter, and Basecamp.
