This week, the heart of internet security is bleeding, stock traders game the system, a Twitter to destabilize Cuba, Game of Thrones pushes piracy to a new high, and are we at 3D printing’s tipping point? All this and more…

Right now, Amazon is selling the Kindle edition of Moneyball: The Art of Winning an Unfair Game by Michael Lewis for only 25 cents! The book is what the Academy Award-nominated Moneyball film (starring Brad Pitt and Jonah Hill, both of whom got Oscar nods for their roles) is based on.

The book is also available in paperback for $9.72 and paperback for $15.82. NOTE – There’s another listing for a Kindle edition, but the price is much higher. Be sure to click HERE for the 25-cent version released in August 15, 2011 (as far as I can tell, the only difference between versions is the updated cover that shows Brad Pitt and boasts that the book was made into a movie starring Pitt).
