Is there a way to detect if a browser window is not currently active?
...
@bellpeace: IE should propagate focusin and focusout from the iframe to the upper window. For newer browsers, you'd just have to handle the focus and blur events on each iframe's window object. You should use the updated code I just added which will at least cover those cas...

Rank items in an array using Python/NumPy, without sorting array twice
... mind the dependency on scipy, you can use scipy.stats.rankdata:
In [22]: from scipy.stats import rankdata
In [23]: a = [4, 2, 7, 1]
In [24]: rankdata(a)
Out[24]: array([ 3., 2., 4., 1.])
In [25]: (rankdata(a) - 1).astype(int)
Out[25]: array([2, 1, 3, 0])
A nice feature of rankdata is that ...

Why does Math.floor return a double?
..., but that would result in a performance impact (no conversion instruction from long to double in any instruction set that I'm aware of). I wonder what Math.floor does with doubles > 2^53 at the first place. Some results aren't representable.

How to find a min/max with Ruby
...
You can do
[5, 10].min
or
[4, 7].max
They come from the Enumerable module, so anything that includes Enumerable will have those methods available.
v2.4 introduces own Array#min and Array#max, which are way faster than Enumerable's methods because they skip calling #each....

Comparator.reversed() does not compile using lambda
...dditional type information that fills this gap. This information is absent from the third line, so the compiler infers u to be Object (the inference fallback of last resort), which fails.
Obviously if you can use a method reference, do that and it'll work. Sometimes you can't use a method reference...
