What exactly are iterator, iterable, and iteration?
...3) method.
Whenever you use a for loop, or map, or a list comprehension, etc. in Python, the next method is called automatically to get each item from the iterator, thus going through the process of iteration.
A good place to start learning would be the iterators section of the tutorial and the i...
Explaining difference between automaticallyAdjustsScrollViewInsets, extendedLayoutIncludesOpaqueBars
...ll/gps/audio notification, navigation bar doesn't have to be always 44 pts etc.
I think the best solution is to use layoutGuide length in didLayoutSubviews:
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()

JavaFX and OpenJDK
...e packages for Linux distributions based upon OpenJDK (e.g. Redhat, Ubuntu etc) to create RPMs for the JDK and JRE that include JavaFX. Those software distributors, then need to place the generated packages in their standard distribution code repositories (e.g. fedora/red hat network yum repositori...
What is std::move(), and when should it be used?
... constructors, operator methods, standard-library-algorithm-like functions etc. where objects get created and destroyed automagically a lot. Of course, that's just a rule of thumb.
A typical use is 'moving' resources from one object to another instead of copying. @Guillaume links to this page which...
What are the disadvantages to declaring Scala case classes?
...r because the change causes a multi-million dollars bug and gets reverted, etc. But if you are writing code for hobby and don't care about users, go ahead.

When should I really use noexcept?
...d to be a runtime evaluation can be turned into a compile-time evaluation, etc.
Anyway, the short answer: noexcept lets the compiler generate a tighter flow graph, and the flow graph is used to reason about all sorts of common compiler optimizations. To a compiler, user annotations of this nature a...

There are many times when you may want a code block to be executed without the existence of a main func, directly or not.
If you, as the developer of the imaginary library, import your library's sub-package that has...
When do you use POST and when do you use GET?
...surd from a security standpoint when it leads to data exposed in log files etc., but it is fail-safe with regards to the server-side data (the serve should not modify data upon a GET).
