What would cause an algorithm to have O(log log n) complexity?
...square root of the size at each layer?
For example, let's take the number 65,536. How many times do we have to divide this by 2 until we get down to 1? If we do this, we get

Change date of git tag (or GitHub Release based on it)
...it checkout SHA1_OF_PAST_COMMIT
git tag -m"Retroactively tagging version 1.5" v1.5
And while that's perfectly usable, it has the effect of putting your tags out of chronological order which can screw with build systems that look for the "latest" tag. But have no fear. Linus thought of everythi...
