Ada's is awesome. It's one of our favorite bookstores in Seattle. They host a number of book clubs, and one their coolest is the Computer Science Book Club. Here is how Ada's describes it, "The Computer Science Book Club is where the experienced and non-experts alike read and discuss important and popular books in computer science that blend broad topics in the subject with nuts and bolt engineering, history, and philosophy. The goal is to more greatly appreciate our everyday laptops, where they came from and where they could take us."
