C++11 introduced a standardized memory model. What does it mean? And how is it going to affect C++ p
...y orderings in strong models are unnecessary. If a thread updates ten data items and then a synchronization flag, programmers usually do not care if the data items are updated in order with respect to each other but only that all data items are updated before the flag is updated (usually implemented...

RSpec: describe, context, feature, scenario?

C# switch statement limitations - why?

With expression sets containing clumps of adjacent items, the compiler may binary tree search, and finally a CIL switch.
This is full of "mays" & "mights", and it is dependent on the compiler (may differ with Mon...

map vs. hash_map in C++
...e O(1) (constant time) where map will be O(log n) where n is the number of items in the data structure. So unordered_map is faster, and if you don't care about the order of the items should be preferred over map. Sometimes you want to maintain order (ordered by the key) and for that map would be t...
log4j logging hierarchy order
