I have two inline-block div elements, that are the same, positioned next to eachother. However there seems to be a mysterious space of 4 pixels between the two divs despite the margin being set to 0. There are no parent divs effecting them - What is going on?

This selects any div that is the first child of the #container div, and no others below it. To generalize the background colors, you can use ...
Why does the expression 0 < 0 == 0 return False in Python?
...tion for them.
With the other cases you talk about, the parenthesis force one relational operator to be applied before the other, and so they are no longer chained comparisons. And since True and False have values as integers you get the answers you do out of the parenthesized versions.

When to use static classes in C# [duplicate]
...of the functionality is the same, but we have to change a couple of parts nonetheless. Had it not been a static method, we could make a derivate class and change the method contents as needed. As it's a static method, we can't. Sure, if we just need to add functionality either before or after the ol...
What is the result of % in Python?
...rst converted to a common type. A zero right argument raises the ZeroDivisionError exception. The arguments may be floating point numbers, e.g., 3.14%0.7 equals 0.34 (since 3.14 equals 4*0.7 + 0.34.) The modulo operator always yields a result with the same sign as its second operand (or zero); the a...

Will strlen be calculated multiple times if used in a loop condition?
...i] != '\0'; i++)
{
//Something;
}
In the above code str[i] only verifies one particular character in the string at location i each time the loop starts a cycle, thus it will take less memory and is more efficient.
See this Link for more information.
In the code below every time the loop runs str...
How is this fibonacci-function memoized?
...(n-2), the function itself gets called, twice from the top, causing the exponential explosion. But with that trick, we set out a list for the interim results, and go "through the list":
fib n = (xs!!(n-1)) + (xs!!(n-2)) where xs = 0:1:map fib [2..]
The trick is to cause that list to get created, ...
