Something about using 'ghost' in place of 'self' in a Shell class (allusion to anime as well). Maybe I did something like this last year (having deja vu again). But I'm realizing edu-sig is no longer a preferred venue for my curriculum writing. I'd rather huddle with MIT, Bruce Sherwood, Alan Kay and play *against* Arthur's team. Arthur, you make too many enemies too quickly and too easily. Even more, I'm into my Portland Knowledge Lab (PKL) business (gotta pay that rent today) and want to make lots of Python and Synergetics teaching cartoons for HDTV (my Saturday Morning meme), with lots of brand name sponsors. But here is not the place to brainstorm in safety. Too many prying eyes and self-appointed kibbitzers. So I'm actually resigning this time. Don't expect me back any time soon. Probably won't be tracking either, at least not with any frequency. For me, it's a tilt towards private lists and closed source development (not exclusively -- I'm still a big supporter of a strong public sector). I'm learning why open source is a bad idea sometimes. I've talked to Stallman about this, though he probably doesn't remember -- I was in his audience in Portland and asked about situations when "they" simply *don't deserve* your best code. But I think more it's a matter of not wanting to show unfinished work (a big no no in Fuller's self discipline, according to 'Critical Path' I think it was). Kirby
