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 ...
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...
Simple way to encode a string according to a password?
...re cipher. It is one of the strongest of the simple ancient ciphers.
Vigenère cipher
It's quick and easy to implement. Something like:
import base64
def encode(key, string):
encoded_chars = []
for i in xrange(len(string)):
key_c = key[i % len(key)]
encoded_c = chr(ord(st...

Why are C# 3.0 object initializer constructor parentheses optional?
...e two cases you probably meant.
Similarly, casts are ambiguous even in C# 1.0:
