I absolutely love the books from “The Pragmatic Programmers“. They are really well written and the cool thing is, you can get them as DRM free PDF. And the even cooler thing is, you buy and read them while there are being written!
How great is that?
Below is a screenshot of my Pragmatic Bookshelf and I can recommend all of the books, except the “iPhone SDK Development” – because I haven’t read it yet.
And if you buy the ebook version (and I usually do, as I don’t like hard copy books for technical literature ) and they correct any errors in the book, you get a free update.
Sometimes they even add further chapters or in case of “Hello Android”, they updated the whole book for a completely new SDK release!
