 So let's get started and I haven't heard the bell ring yet, but I don't know if that's going on at this time. Anyway, so this is it. This is the last day of the conference. Soon we go home, feeling kind of sad to leave here. It's been a great week. So was anyone at the talk I did yesterday? No, great. So no overlapping audiences, which means I'll be making new acquaintances. Right. So this is kind of a mysterious title, but I will explain in a moment the leprechauns of software engineering. So who's a software engineer? Not so very many of you. All right. So maybe this is kind of superfluous, but still a lot of what we do in software development is seen as belonging to that particular discipline, software engineering. And many of the things we talk about in the agile community take place within the context of a debate which started in the late 60s, 1968 was the date when people came up with this notion that there is such a thing as software. There are some disciplines concerned with the engineering of various things. So why not apply the notion of engineering to software? And this was born software engineering. That was not something which came naturally. Initially the phrase software engineering was seen as provocative. That's another talk when I've given before on the history of software engineering and the continuity between the history of software engineering and that of agile. But I wanted to briefly bring some of that background to this talk. Now, a different kind of history when I was a kid, used to read the comics. Any of you remember that?
