I was just surprised, and somewhat delighted, by a LinkedIn connection request. Not that receiving connection requests from LinkedIn is in itself an unusual thing – I get several a week from various sources. This one was unusual because the sender made reference to liking a Java Ranch forum post I made over sixteen years ago
I re-read the post, and could see that several people had bumped into it, and found it useful, over the intervening years, which was certainly very pleasing. It brought to mind the thought that, even in the fast-paced world of computer programming, there is value to history and theory. Not everything which is old is useless, and some concepts exist in the abstract, separate from particular implementations, yet useful for understanding those implementations.
