I wish someone would provide an early access book on Rust (even if it is a bit of a moving target).
Have you picked up any O'Reilly books recently? The quality is completely variable from title to title. Of the last 3 O'Reilly books I've purchased, 2 were absolute shit.
I've noticed that Manning's MEAP process works to keep errors out and quality high.
Node In Action is probably the most beautiful JS example code I've ever seen in a book.
I wish someone would provide an early access book on Rust (even if it is a bit of a moving target).
