An anonymous reader writes: There is a excellent interview over at the H with Linus Torvalds. Glyn Moody's second interview with Linus since 1998 is both informative and revealing. Linus response to his role as the kernel maintainer has this interesting tidbit: "Well, the big thing is I don't read code any more... when it comes to the major subsystem maintainers, I trust them because I've been working with them for 5, 10, 15 years, so I don't even look at the code." The interview goes on to talk about Amazon, Google, phones tablets and the cloud. Further on the topic of coding, the interview ends with Linus stating: "When I was twenty I liked doing device drivers. If I never have to do a single device driver in my life again, I will be happy. Some kind of headaches I can do without." Like all of us, Linus is getting older and taking a less hands on approach to the development of the kernel. Of course this is understandable. Even the great Git himself is a slave to the passage of time, but thankfully for us, his creation is not.
What this article never really manages to describe is Envelope Tracking (ET). This has been in development for several years. Look at the diagram in http://www.nujira.com/technology-pa-746.php for a better description of the concept. This article describes the application of ET in the handset.
All of this is really strategic positioning ahead of next summer's launch of the all-new iPhone 5S, where they'll start using a great new marketing campaign: "It just works!" It'll be time to turn the crank and ring the cash register again by then.
I don't have the book in front of me, but Jobs issue with flash was personal. As I recall, Adobe didn't do something he had expected years prior. He had a good memory and never would have chosen flash since it was personal.
