The Humble Hacker?
Two of our favorite things have come together: The Humble Bundle and Hacking! The folks at No Starch Press have created a bundle of ebooks that is easy to justify, because you set the price!
Whether you want to spend pennies to get a few awesome books or spend $15 to get all 13 books, there's really no reason not to go pick them up. As with all books sold via Humble Bundle, they are DRM-free, multi-format, and available for immediate download. Plus, you can buy them with Bitcoin if that's the sort of thing your'e into!
Head over to Humble Bundle and check out the titles. Be sure to decide before May 11, 2016 though, because the Humble Bundle is always a limited-time offer.
