rsync copy over only certain types of files using include option
...*" --include="*.sh" "$from" "$to"
For rsync version 3.0.6 or higher, the order needs to be modified as follows (see comments):
rsync -zarv --include="*/" --include="*.sh" --exclude="*" "$from" "$to"
Adding the -m flag will avoid creating empty directory structures in the destination. Tested in ...
In Functional Programming, what is a functor?
...ule that provides:
The type of key to be used in the binary tree
A total-ordering function on keys
Once you've done this, you can use the same balanced binary tree implementation forever. (The type of value stored in the tree is usually left polymorphic—the tree doesn't need to look at values...

How do I adjust the anchor point of a CALayer, when Auto Layout is being used?
...of the View when first called and reuses that Position in further calls in order to place the View accordingly. This overwrites the Autolayout Code in that sense, that it takes place after [super layoutSubviews]; which contains autolayout Code.
Like that there is no longer any need to avoid Autolay...
Why does i = i + i give me 0?
...rator -.
If an integer addition overflows, then the result is the low-order
bits of the mathematical sum as represented in some sufficiently large
two's-complement format. If overflow occurs, then the sign of the
result is not the same as the sign of the mathematical sum of the two
oper...

A shorter alternative, that is not as easy to understand:
WITH x AS (SELECT n FROM (VALUES (0),(1),(2),(3),(4),(5),(6),(7),(8),(9)) v(n))

Is python's sorted() function guaranteed to be stable?
..., 1), (1, 2)] instead of returning the original input in the same sequence/order. Shouldn't the guarantee of stability mean that it should be returning the original [(1, 2), (1, 1)] input? In that case, you have be explicit and say sorted([(1, 2), (1, 1)], key=lambda t: t[0])

John Carmack's Unusual Fast Inverse Square Root (Quake III)
.....discarded...]
And the task has now came down to calculate a0 and a1 in order for y to have the least difference from the exact value. They have calculated that the most appropriate values are:
a0 = 0x5f375a86
a1 = -0.5
So when you put this into equation you get:
y = 0x5f375a86 - 0.5*x

How does the Comma Operator work
... guaranteed to have its three subexpressions (a+b, c() and d) evaluated in order. This is significant if they have side-effects. Normally compilers are allowed to evaluate subexpressions in whatever order they find fit; for example, in a function call:
someFunc(arg1, arg2, arg3)
arguments can be ...
