The Icarus Deception by Seth Godin
This is the first Seth Godin book I've ever read. Over the years I have read a lot of things on his blog that were promoted in tweets and posts by almost everybody I follow online. I'm not sure why it took me so long to actually read one of his books. This book is well written and inspiring. I have thought similar things to what Seth writes about in The Icarus Deception but I was never able to clearly articulate those ideas. Seth is a great writer and has really helped me to open my mind to a number of new ideas and clarify many ideas that I was still trying to process.
The Manga Guide to Linear Algebra by Shin Takahashi & Iroha Inoue
I teach an introductory course in game development to second year students where I work. It has proven to be a challenge due to the fact that many of them are not very far along in their mathematical studies. I don't believe that you need a couple of semesters of Calculus to learn Linear Algebra and I think I do an OK job of teaching the basics. I've never been able to find a book that was able to work in the context of this course until now. I'm going to test The Manga Guide to Linear Algebra as a textbook, along with the Unity 3D programming book I use, in the Fall 2013 semester. I think it will help students to more quickly grasp these concepts and gain a deeper understanding of the subject matter. If I remember I'll be sure to write a post-mortem after the course is over about how well the book served the needs of my students.
