(2013). There are many comments since then providing more alternatives, many of which didn’t exist back in 2013, but the article itself hasn’t been touched since 2013-07-07.
While the author hasn’t updated the main link, it’s clear he checked up on the article until atleast 2017: one of the comments originally was a base64 encoded string, and the author edited and deleted it so that no one would run random base64 strings off the internet.
