Definitive and most up to date? Without question. Best? That's arguable, and depends on the code base. Learning a language from the source (say Python or SQL) is a really bad idea. Best practices and KISS for the code is not something you'll learn from that.

"In Apple's defense, this is done in the name of protecting the consumers from malicious, slimy, or defective applications. Sort of like Nintendo's Seal of Approval, I guess." Considering that some of the games that consistently make the "worst of all time" list have that seal, it didn't work out so well.

Something for you to think about the next time you feel like getting something like pokemon: Critics who treat adult as a term of approval, instead of as a merely descriptive term, cannot be adult themselves. To be concerned about being grown up, to admire the grown up because it is grown up, to blush at the suspicion of being childish; these things are the marks of childhood and adolescence. And in childhood and adolescence they are, in moderation, healthy symptoms. Young things ought to want to grow. But to carry on into middle life or even into early manhood this concern about being adult is a mark of really arrested development. When I was ten, I read fairy tales in secret and would have been ashamed if I had been found doing so. Now that I am fifty I read them openly. When I became a man I put away childish things, including the fear of childishness and the desire to be very grown up. --CS Lewis
