Why would one use nested classes in C++?
...rivate and hidden the builders of the STL were able to update the code without affecting how you used the code, or leaving a lot of old baggage laying around the STL because they need to maintain backwards compatibility with some fool who decided they wanted to use the Node class that was hidden ins...
Why doesn't the height of a container element increase if it contains floated elements?
I would like to ask how height and float work. I have an outer div and an inner div that has content in it. Its height may vary depending on the content of the inner div but it seems that my inner div will overflow its outside div. What would be the proper way to do it?

Why does Python code run faster in a function?

When to make a type non-movable in C++11?
...such as int can't move: moving them is just a copy. You can't rip the guts out of an int, you can copy its value and then set it to zero, but it's still an int with a value, it's just bytes of memory. But an int is still movable in the language terms because a copy is a valid move operation. For no...
How does libuv compare to Boost/ASIO?
...ia the environment variable UV_THREADPOOL_SIZE. The work will be executed outside of the event loop and within the threadpool. Once the work is completed, the completion handler will be queued to run within the event loop.
While Boost.Asio does not provide a threadpool, the io_service can easily f...
What are some compelling use cases for dependent method types?
...e to a need for dependent method types. In particular, I maintain that without dependent method types the classic cake pattern is closer to being an anti-pattern.
So what's the problem? Nested types in Scala are dependent on their enclosing instance. Consequently, in the absence of dependent method...
What are the differences between the threading and multiprocessing modules?
...erver or GUI app is to allow you to do long-running "background tasks" without stopping the main thread from continuing to service network packets or GUI events. And that works just fine with Python threads. (In technical terms, this means Python threads give you concurrency, even though they don't ...
Why do people say there is modulo bias when using a random number generator?
...
Another way of thinking about_RAND_MAX%n == n - 1_ is (RAND_MAX + 1) % n == 0. When reading code, I tend to understand % something == 0 as “evenly divisible” more readily than other ways of calculating it. Of course, if your C++ stdlib has RAND_...
