Which concurrent Queue implementation should I use in Java?
... behavior.
Taking the easiest first, ArrayBlockingQueue is a queue of a fim>x m>ed size. So if you set the size at 10, and attempt to insert an 11th element, the insert statement will block until another thread removes an element. The fairness issue is what happens if multiple threads try to insert and ...
How to create a density plot in matplotlib?
....5]*2 + [3.5]*8 + [4.5]*3 + [5.5]*1 + [6.5]*8
density = gaussian_kde(data)
m>x m>s = np.linspace(0,8,200)
density.covariance_factor = lambda : .25
density._compute_covariance()
plt.plot(m>x m>s,density(m>x m>s))

I get
which is pretty close to what you are getting from R. What have I done? gaussian_...
What is the difference between Pan and Swipe in iOS?
...pe is a pan but a pan may not be a swipe, so the pan recognizes first and em>x m>cludes other recognizers.
You should be able to resolve this conflict using the delegate method gestureRecognizer:shouldRecognizeSimultaneouslyWithGestureRecognizer:, or perhaps without delegation by making the pan recogniz...

Create an empty list in python with certain size

Assigning a value to an em>x m>isting element of the above list:
>>> l[1] = 5

Keep in mind that something like l[15] = 5 would still fail, as our list has only 10 element...
Why are floating point numbers inaccurate?
...ing point numbers are represented a lot like scientific notation: with an em>x m>ponent and a mantissa (also called the significand). A very simple number, say 9.2, is actually this fraction:
5179139571476070 * 2 -49
Where the em>x m>ponent is -49 and the mantissa is 5179139571476070. The reason it is i...
