I was going to post a comment about the regex used to (coarsely) validate email addresses made no sense, but when I opened the article in a new tab to copy for quoting, it had changed. :) It's now "^[^@\\s]+@\\S+$" with a comment also stating that it could be better. That's at least sensible, the original one that I first saw was more or less "^[^@]@.*" which kind of makes no sense. Oh well, great that the author caught it, of course.
