Two new Amazon reviews for my book, Video Compression for Flash, Apple Devices and HTML5, both 5 star, though the UK review was kind of … mixed, shall we say. In the States, John Talbert was pretty positive, stating “This book is very technical and detailed. It is the perfect tool to help you decipher all the techno jargon found …
