The Free Library of Philadelphia is hosting a brainstorming session this evening, seeking ideas for a new space it wants to open next year.It has an unexpected plan for this new ‘common’ space: No books. Or, at least, as few as possible. It also has an unexpected consultant: Hactory director Georgia Guthrie. (The hactory is a group of art and technology enthusiasts that wants to make technology access more equal.) She says the 5,000 square-foot space should serve the community in a modern, flexible way. “For the Hactory we would love to have a basic soldering class there, or maybe our intro to arduino class,” said Guthrie. For those who don’t speak hack, that’s a basic circuitry class, and a class about building micro-controllers to for mini-robots. Guthrie will be one of the discussion facilitators tonight — architects, public artists and community organization leaders will also attend. If you haven’t already signed up you’re out of luck — registration is closed.
