How to list branches that contain a given commit?
... cherry:
Because git cherry compares the changeset rather than the commit id (sha1), you can use git cherry to find out if a commit you made locally has been applied <upstream> under a different commit id.

Why was “Avoid Enums Where You Only Need Ints” removed from Android's performance tips?

I think one of the most powerful reasons to use import * in an __...
What's the fastest way to loop through an array in JavaScript?
...fo
Currently, the fastest form of loop (and in my opinion the most syntactically obvious).
A standard for-loop with length caching
var i = 0, len = myArray.length;
while (i < len) {
