They're working at making smaller apps on people's iPhones. They strip out all the graphics that don't apply to the given phone that's downloading on, plus bitcode is compiled for the specific architecture, so you don't have multiple architectures installed that you don't need.

Often, it's really bad design. For instance, Facebook's app has 18k classes. In other cases, it's a lot of big 3rd party libraries.

The base for iPhones now is 32G not 16G.

That's the difference between a freshman design project and an actual design used in practice. It's unlikely he has the mathematics/engineering background to do a proper analysis of his design.

He's not thinking of the bottle as a pressure vessel (which it is).

The box set for David Bowie's Sound + Vision album included a fourth CD that included an extra video track in addition to three regular CD audio tracks.

The term "killer app" goes back a long way (back to the early 80s) and was first used for Visicalc, I think.

I love that a technique that's so widely used now was the co-invented by a movie star. It's also used in cell phones.

Looking at the info about the formats for that book it seems that the ePub and PDF are unrestricted.

I've never really had a problem with the watermarking in the footer with the person who bought it. It's out of my way so I tend to forget about it.
