... inherited arrays from C where they are used virtually everywhere. C++ provides abstractions that are easier to use and less error-prone ( std::vector<T> since C++98 and std::array<T, n> since C++11 ), so the need for arrays does not arise quite as often as it does in C. However, whe...
Unicode equivalents for \w and \b in Java regular expressions?
...everything work right again. It’s available as an embeddable (?U) for inside the pattern, so you can use it with the String class’s wrappers, too.

Should a Netflix or Twitter-style web service use REST or SOAP? [closed]

What exactly does git's “rebase --preserve-merges” do (and why?)
...
As with a normal git rebase, git with --preserve-merges first identifies a list of commits made in one part of the commit graph, and then replays those commits on top of another part. The differences with --preserve-merges concern which commits are selected for replay and how that repla...
