How does StartCoroutine / yield return pattern really work in Unity?
...calculates the next value in the sequence (returning false if there are no more values), and Current retrieves the value it calculated.
Ordinarily, if you wanted to implement an interface, you’d have to write a class, implement the members, and so on. Iterator blocks are a convenient way of i...

What to do about a 11000 lines C++ source file?
...le permanently, perhaps by renaming it in each branch. It's not "main" any more, it's "main for configuration X".

The git-hg script (formerly maintained here) uses a different method, based on hg-fast-export from the fast-export project. Like method 2, this also keeps a bare Mercurial repository and an additio...
Effective way to find any file's Encoding
...king at the reference source for StreamReader, that implementation is what more people will want. They make new encodings rather than using the existing Encoding.Unicode objects, so equality checks will fail (which might rarely happen anyway because, for instance, Encoding.UTF8 can return different ...
