Making git use Sublime Text

First up, let's make Sublime Text 2 available from the command line in terminal, by creating a link to subl which is the launcher from terminal:

ln -s /Applications/Sublime\ Text\ 2.app/Contents/SharedSupport/bin/subl /usr/local/bin/sublime

(added bonus of this approach is when you upgrade to ST3 or change text editor, you can just redirect the symlink).

If there's any chance that bash doesn't check usr/local/bin then use [Launch Sublime Text 2 from Mac OSX Terminal] for more detailed instructions on how to make this happen.

There was [a tweet][tweetSoto] a couple of days ago that resulted in a discussion/question about what it wrong with the usage of removedOnCompletion = NO in the [SparkRecordingCircle code][code] for that [Subjective-C post][post].

We all kept saying that the explanation doesn't fit in a tweet, so here is my rough explanation about the issues.

But, let me first say that I think that the Subjective-C articles are reallt cool and useful to learn from. This is trying to reason about the general usage of removedOnCompletion = NO, using that code as an example, since that was what was discussed on twitter.

---

The root problem, as [Nacho Soto pointed out][rootProblem], is that removedOnCompletion = NO in combination with fillMode = kCAFillModeForwards is almost always used when you are not updating the model layer. This means that after the animation has finished, what you see on screen is not reflected in the property of the layer. The biggest issue that this can cause is that all the
