Another tech term is making the rounds: "Comet." It doesn't stand for anything. Comet describes a type of client-server interaction that is like Ajax, but "Comet applications can deliver data to the client at any time, not only in response to user input," according to Alex Russell in his seminal article on this topic (makes me think of good old 'keep-alive'). Seminal, at least, according to this article in Comet Daily the weblog devoted to Comet. Is there a point to this? Yes, it has always been useful for "chat, games and real-time monitoring of prices and states." Will the term survive? Hard to say - but there is some tech behind the concept, so even if the name fades, the idea won't. Via Simon Willison.
