I'll be at HOPL tomorrow morning. The first talk is about AppleScript.

William R. Cook: AppleScript

There are some interesting details about the relationship between AppleScript and Frontier that I didn't know before. According to Cook, at one time Apple considered purchasing Frontier from UserLand rather than create its own language, but the deal fell through. Also, OSA was created because Dave Winer convinced Apple that having only one language would be bad for the Mac.
