How to calculate moving average using NumPy?
...lso yield:
list(mov_avg(x, 2))
# [4.0, 5.5, 9.0, 6.0, 1.5, 3.0, 3.0, 0.5, 1.0]
So what is being done at each step is to take the inner product between the array of ones and the current window. In this case the multiplication by np.ones(w) is superfluous given that we are directly taking the sum ...
Best practices for catching and re-throwing .NET exceptions
What are the best practices to consider when catching exceptions and re-throwing them? I want to make sure that the Exception object's InnerException and stack trace are preserved. Is there a difference between the following code blocks in the way they handle this?

How do I wait for an asynchronously dispatched block to finish?
... expose real behavior to the rest of the app than hide it behind a false façade.
Instead, use NSNotificationCenter, define a custom delegate protocol with callbacks for your class. And if you don't like mucking with delegate callbacks all over, wrap them into a concrete proxy class that implemen...

Vigenère cipher
It's quick and easy to implement. Something like:

key_c = key[i % len(key)]
encoded_c = chr(ord(st...
Why are C# 3.0 object initializer constructor parentheses optional?

Similarly, casts are ambiguous even in C# 1.0:
