There is currently no easy way to determine where the canonical data in a complex system resides and how it is updated, and my bet is we will see a new set of tools and languages evolve to create abstractions which will make it possible for mere mortal programmers like myself to get these architectures right.

Summary: there is no silver bullet.

Kellan points out a great follow-up to the previously linked Michael Wolfe piece. While the Wolfe piece is extremely entertaining, it’s also very true that there are smart ways to approach planning for software development. The value of experience cannot be overstated in these situations.

I don’t understand why the studios seem so intent on driving people to pirate movies. The experience (warnings about piracy, trailers, etc.) with a legitimate DVD or Blu-Ray is already awful and it seems they are trying to make it worse.

It’s no longer possible to write a single app that takes advantage of the full range of Mac OS X features. Some APIs only work inside the Mac App Store. Others only work outside it. Presumably, this gap will widen as more new features are App Store–exclusive, while sandboxing places greater restrictions on what App Store apps are allowed to do.

A must-read. (thanks Sean)

All variations of this are great.

Insightful overview, as usual, from Steve.
