I'm no longer with OpenCola.
Like many of my projects to date, beepcore-ruby is in a holding pattern. I'm negotiating the purchase of some equipment from OC, but it'll be two Apple machines at most (a G4 minitower and a G3 Pismo PowerBook), and unfortunately, Ruby doesn't run on Mac OS 9 (I heard tell of a really old port, but my question to ruby-talk on the matter of locating source code that I could perhaps try to bring up to date went unanswered). The upside is that I'm working on BEEP in Squeak (beepcore-squeak?) instead. I'm not sure if I'm going to release it, but I suppose I may as well. I'm doing it because Ruby and Smalltalk are similar, and I can port what I do in Squeak over to Ruby. It means that beepcore-ruby won't be available for a while, but perhaps the resulting additional code base will make up for it.
I have, as always, been tinkering with some other stuff recently. I'm hacking on a Lisp system for Mac OS 9, fiddling with Forth, Haskell, and Clean, and toying with some other things. I've created a docket of my current projects, to help me manage my time better. You'll be able to view it and do other snazzy things with said docket when I launch my long delayed web site.
Like stevej and nchriss, I've been thinking about OpenCSP and similar topics. I'm also interested in working on an idea I spouted off about to the e-lang list back in May; an implementation of capabilities in monads.
