Linux Conference Australia, Ballarat 2012. The creator of Busybox and co-founder of Debian makes a compelling and rational argument about who should speak for Open Source, and then offers a hopeful perspective on the new frontiers of Open Source Hardware. He is convinced that today there’s plenty of enabling factors to make Open Source Hardware […]
