Just viewed the videos by Cliff Hastings for Wolfram. Surprised to see that there looked like an error in the second video on making a first order fit showing the line going above the origin when x=0. Later it showed it correctly. Sent him a note about that.
But what really bothers me about demos like this is that they look so easy when they do it, but if I were to try to do it I wouldn't know where to start. He implied that one could do it without knowing much of anything of their system. I really get tired of videos like this where they type really fast and it looks so easy if one just knew their system well, but I usually don't. If I was presented that screen and wanted to do what he did I wouldn't have a clue what to do. We need to present similar videos on J, but somehow we need to make it obvious and logical as to what to do. His video was neat, but could I do it as quickly and easily as he did it without putting in hours, possibly days learning their system? I doubt it.
