Stone fruit (peaches, plums, apricots, nectarines) are in season in the summer and easily bruise and get brown spots when they overripen.

Warning: Just as with UIScrollView, there's a lot more to getting this one right than it initially may seem... But here's probably the next thing I'd address: http://en.m.wikipedia.org/wiki/Gimbal_lock

Honestly... I just had a habit of checking up on him every once in a while. Came upon this today when someone brought him up and I thought to check in. It's been there for weeks and somehow no one else noticed.

This approach to the "do" syntax requires that the function implementer know the monad type a priori. That defeats some of the purpose of monad as general abstraction. One of the big ideas here, as far as I'm concerned, is that monads repre

Many of these are places where people are caching rasterizations of deep layer hierarchies to avoid paying the compositing cost on a per-frame basis. But if you do that with drawRect:, you're using the CPU (not the GPU); if you use your own

Render the gradients into a resizable UIImage via CG. That differs from approach #2 in the article, which does the same thing, but generates a non-resizable UIImage. To make a resizable image at runtime, draw into an image as described in a

It's not really true that all techniques perform fine if you're rendering just one button. If you're using a masked CALayer, and that layer's in a scroll view or is otherwise animating around the screen, there's a very real chance that you'

It's true: you could fix these specific bugs with JavaScript (though I don't know if you could ever get Services working!) But you'd get a huge amount of standard behavior if your code editor were based on Cocoa's text system. As it stand

Now, I'm not trying to incite a native vs. web flame war here, but I believe that building separate native UI layers would have actually been much better. I hope I can provide some constructive criticism on the native app for the Mac: The a

Yaser Abu-Mostafa was (by enormous margin) the most effective professor I had at Caltech. Despite being such an expert in the field, he understands clearly when a concept is particularly challenging--and what about it makes it so. This clas
