How can I perform a culture-sensitive “starts-with” operation from the middle of a string?
... mapping.
You would need to know the length of the substring that was actually matched. But Compare, IndexOf ..etc
throw that information away. It could be possible with regular expressions but the implementation doesn't do full case folding and so doesn't match

What would cause an algorithm to have O(log log n) complexity?
... n) terms can show up in a variety of different places, but there are typically two main routes that will arrive at this runtime.
Shrinking by a Square Root
As mentioned in the answer to the linked question, a common way for an algorithm to have time complexity O(log n) is for that algorithm to work...
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...

Never ever use global context. ObjectContext internally implements several patterns including Identity Map and Unit of Work. Impact of using global context is different per application type.
For web applications use single context per request. For web services use single con...
