If you want to learn more about what the Ruby VM has to do in order to execute your code, and some of the performance challenges for Ruby implementors (such as it's extremely flexible parameter parsing) I suggest this talk by Koichi Sasada: http://www.youtube.com/watch?v=lWIP4nsKIMU

I really wish this talk had been done by someone who spoke english, I found it rather painful to try and get through...

Any good articles that summarize this info?

I find this attitude a bit entitled. The speaker does speak English, his accent is just not very understandable.

However, opening the video and seeking to a random point, I must say that the phrase "Ruby release policy: Ruby level compatibility" isn't doing any Japanese speaker a favour.

You find his attitude entitled, I find your reply needlessly confrontational.

It's not like chadcf said "This talk is bullshit, that guy doesn't even speak English". chadcf said "I experienced this difficulty, I wish that the following thing existed, can anyone help me?" Maybe he could afford to have done
