UIVisualEffectView blur radius manipulation (new for iOS 9)
View gist:27829d87118d984232a4
// iOS 9 allows you to animate between visual effects, which gives you the
// ability to manipulate the blur radius. this can be useful for animating
// a backdrop for a custom modal, and with a few tricks, can even be set
// indirectly, allowing you to "scrub" between them back and forth with
// a gesture, just like when you pull down Spotlight.
// these are the two effects you want to transition between
UIVisualEffect *startEffect = nil; // "nil" means no blur/tint/vibrancy (plain, fully-transparent view)
UIVisualEffect *endEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleLight];

simple squash without rebase
View gist:9515611
## within current branch, squashes all commits that are ahead of master down into one
## useful if you merged with upstream in the middle of your commits (rebase could get very ugly if this is the case)
## commit any working changes on branch "mybranchname", then...
git checkout master
git checkout -b mybranchname_temp
git merge --squash mybranchname
git commit -am "Message describing all squashed commits"
git branch -m mybranchname mybranchname_unsquashed
git branch -m mybranchname
