Some interesting Rubinius blog posts in the last couple of days. First, Brian Ford showed us what’s next for Rubinius (including scarily good concurrency, Windows support, JIT fun and more) and then Yehuda Katz decided to get us comfortable with Rubinius’ pure Ruby internals. There’s a lot of great stuff to pick up from both of these posts if the nitty-gritty of implementing Ruby interests you.
