Started this morning with Martin Fowlers talk. Well done. Good stuff. No complaints. It was about finding desings and patterns and process we go through, as we gain experience doing so.
Meant to go to the panel afterwards... instead had fun showing some others VisualWorks on Mac OS X, swapping stories about it. Showing off SUnitToo/ExtraRBForSUnitToo. Talked about object based (rather than symbol based) event/change frameworks.
Then moved into the "courtyard" to look at Roel's type inferencer thing. Download RoelTyperUI from the OpenRepository to play with it. It adds a list of inferred instance variable types for the selected class, right alongside the the source code. It runs quite fast. As in, less than 20 milliseconds usualy, so you don't really notice it at all. It doesn't do temps and/or args (yet). Interestingly enough, I was sitting there looking at TestCaseTest and noticed that one of my ivars (didSetup) was typed True. I questioned it. It should be Boolean. It turned out I didn't have an initialize method to set it to false to really verify that the setup method fires. Kinda cool. Not really a bug, but once fixed "more correct" code. See, if we Smalltalkers only had a real type system....chuckle. Anyway, we talked about using this for an auto complete tool (people keep bugging me about this auto complete notion, weird). There's also some well written tests for it in package RoelTyperTests. I ran them as SUnitToo tests of course. :)
Spent my remaining hour or so talking to Andreas Raab and other's about TeaTime particulars, HP's self destruction, "biological" metaphors for programming, security, etc. These are the kinds of discussions that really make OOPSLA fun.
Some "final conclusion" thoughts to follow probably.
