I'm currently on a plane flying home from the bay area. I just spent the last two days participating in the latest rubinius sprint. (I had to go hem early to teach my ruby class).
So, we got the go ahead/mandate to drop the secrecy. Eric Hodel and I are joining Evan Phoenix at Engine Yard to work on rubinius. This is just about the most bad-ass job I could possibly get (my dreams of becoming an astronaut long-dashed against the rocks of horrible vision and only marginally better grades).
I'm only just digging in. Last night I made some changes to autotest that will make it possible to be used with mspec (rubinius' mini version of rspec). This should help accelerate development.
I'm also feverishly working on a new ruby parser written in pure ruby (+ racc) that outputs the same as ParseTree. I'm 99% done (measuring against my tests + dynamic tests generated from stdlib+all my rubygems). I hope to have a release soon. It does have a long way to go after correctness has been addressed. Namely, it is a port of a port and could use a lot of clean-up esp now that we have the true power of ruby behind it.
Anyhow. I'm terribly excited by this. I can't wait to see where we go next.

This is awesome news Ryan. I can't wait to see where you go guys go next either. Congrats to both you and Eric.
Congrats! Keep us informed of how it goes. The Rubinius project has intrigued me for a long time and I wish them all the best of luck.
Great news, Ryan (and Eric) -- for you, Engine Yard, and Rubinius... not to mention the community. Looking forward to seeing the results!
Great stuff, Ryan. Congrats. Sounds like a win-win for all involved.
Woo hoo! Now you can complain about your parser to folks who have a clue what you're talking about.
...Congrats! sounds awesome. Hey does this mean there's any possibility in Ruby Class 3 we will get to have a bit of an overview and couple homework assignments utilizing Rubinius? (first thing's first, I have to get thrashed by your code review in the upcoming homeworks! Awesome class, btw) Congrats and cheers-
That's great news. More people working more on Rubinius.
BTW: I'm sure Racc is more mature, but I'm really loving TreeTop and it's PEG packrat parsing. It would be interesting to see a PEG based grammar for Ruby.
