Brown Dogs and Barbers, the computer science book for everyone, is now available to buy online. There's even a new landing page where you can find free excerpts and links to online shops: browndogsandbarbers.com.
Right now you can get it from several distribution channels, including Amazon (find it your nearest Amazon outlet, like the US, Canada, UK or Germany) and Smashwords. Other retailers, like iTunes, are also currently preparing it for sale in their webstores. More news on those as I receive word.
