Stack Overflow is a familiar, and cherished, name to many a programmer these days. No wonder, as it is nothing short of an ingenious way of finding answers to the many problems you come across as you’re writing code. Myself I can’t remember the last time I consulted a book on programming, since starting to use SO many years ago. One of the cool things about the site is that you write your questions/answers in the (now ubiquitous) Markdown language, which is a quite readable little language that translates to HTML with support for simple formatting such as italic and bold text, plus, not least, code blocks.
