What Is Base64 Encoding and How Does It Work? Sooner or later every web worker runs into a long, mysterious string that looks like aGVsbG8gd29ybGQ= and wonders what on earth it is.

How to Write Headlines That Rank and Get Clicked Your headline does two jobs at once, and most writers only think about one of them.
