How is the fork/join framework better than a thread pool?
...econds, not 11.
EDIT: As Joonas points out, tasks are not necessarily pre-allocated to a thread. The idea of fork/join is that a thread can choose to split a task into multiple sub-pieces. So to restate the above:
We have two tasks (ab) and (cd) which take 2 and 11 seconds respectively. Thread 1 s...
How to convert a number to string and vice versa in C++
...roduced in header charconv.
std::to_chars is locale-independent, non-allocating,
and non-throwing.
Only a small subset of formatting policies used by
other libraries (such as std::sprintf) is provided.
From std::to_chars, same for std::from_chars.
The guarantee that std::f...
C++ project organisation (with gtest, cmake and doxygen)
... (e.g., the "Doxyfile.in" that I put in the folder layout above) which has tokens to be found and replaced by CMake's parsing commands. In my top-level CMakeLists file, you will find one such piece of CMake kung-fu that does a few fancy things with cmake-doxygen together.

Where and why do I have to put the “template” and “typename” keywords?
...t, so that you need the keyword less often. Note that in your example, the token is ambiguous and only after you have seen ">" after double, you can disambiguate it as a template angle bracket. For further details, I'm the wrong person to ask, because I have no experience in implementing a C++ co...
What is the correct way of using C++11's range-based for?
...nt code, e.g., if these elements are instances of std::string,
heap memory allocations can be done, with expensive trips to the memory manager, etc.
This is useless if we just want to observe the elements in a container.
So, a better syntax is available: capture by const reference, i.e. const auto&...
Hidden Features of MySQL
...le resource when setting these parameters. For example sort_buffer_size is allocated only if MySQL needs to do a sort. Note: be careful not to run out of memory.
If you have many connects established (i.e. a web site without persistent connections) you might improve performance by setting thread_ca...
Differences and relationship between glActiveTexture and glBindTexture
...texture, but they do not technically change its state. The Image functions allocate texture storage and set the texture's format; the SubImage functions just copy pixels around. That is not considered the texture's state.
Allow me to repeat: these are the only functions that modify texture state. g...

What is a NullPointerException, and how do I fix it?
...e initialize like this:
private static String[] foo = new String[2];
we allocate a String[] with two elements that are initialized to null. After that, we have not changed the contents of foo ... so foo[1] will still be null.

Is quitting an application frowned upon?
