CI case insensitive comparisons so 'ABC' would equal 'abc'
AS accent sensitive, so 'ü' does not equal 'u'

Remove secure warnings (_CRT_SECURE_NO_WARNINGS) from projects by default in Visual Studio
Is there a way to set by default for all projects removing the precompiler secure warnings that come up when using functions like scanf(). I found that you can do it by adding a line in the project option or a #define _CRT_SECURE_NO_WARNINGS in the beginning of the code.

Standard way to embed version into python package?
...is also used in lots of 3rd-party modules, so it's the quasi-standard.
Usually, __version__ is a string, but sometimes it's also a float or tuple.
Edit: as mentioned by S.Lott (Thank you!), PEP 8 says it explicitly:

How do I avoid capturing self in blocks when implementing an API?
...ied inside the block (we're not doing that) but also they are not automatically retained when the block is retained (unless you are using ARC).

Why prefer two's complement over sign-and-magnitude for signed numbers?
...o add them.
Two's complement addition is very simple. You add numbers normally and any carry bit at the end is discarded. So they're added as follows:
0010
+ 1111
=10001
= 0001 (discard the carry)
0001 is 1, which is the expected result of "2+(-1)".
But in your "intuitive" method, adding is m...
