I'll be presenting our paper "Specializing Ropes for Ruby" at tomorrow. I think the paper is quite accessible if you want to give it a read. The pre-print is available on The Ruby Bibliography:

I'm happy to say TruffleRuby 1.0.0 RC 6 is now out. You'll probably have to update master in your ruby version installer of choice.

We fixed quite a few bug and filled in some performance gaps. A lot of this was based on user bug reports. If you're interested, please give it a whirl and report any issues you encounter.

Hello. This is my first toot, so there's a lot of pressure.

I'm from the greater Boston, MA area and have been using Ruby for a bit over a decade now. I've been involved with open source projects since 1999.

I currently work full time on TruffleRuby. If anyone's interested in trying out TruffleRuby, feel free to reach out. Otherwise, I'm happy to field any general Ruby questions as well.
