Then you're in the right place: CodeFX.org is now nipafx.dev! It's the same content (spicy Java) by the same guy (me, Nicolai - nice to meet you!), but with a new look and without CodeFX as a middleman. From now on, it's just You. Me. Java.
(and tell me again next time I'm forwarded)
By the way, it looks like you didn't get forwarded to the page you were looking for. If that's indeed the case, it would be great if you could let me know, so I can fix it.
