For those who missed it, a HN user is working full-time on dynamic optimizations in Ruby (just finished his PhD thesis on it) - <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10791428" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10791428</a> - It&#x27;s showing significant (10x) speed-ups using real interesting methodologies. He&#x27;s working on it full-time as the project lead at Oracle now. That thesis is worth a week-end read, it&#x27;s something I would dedicate 4-6 lectures to if I was a professor.
