This Week in Ruby: Matz on Ruby 2.0, Numerous Conference CFPs, Tenderlove on define_method

By Peter Cooper / March 7, 2013

Welcome to this week’s roundup of Ruby news, articles, videos, and more, cobbled together from my e-mail newsletter, Ruby Weekly. Sorry these roundups have been missing for a couple of months, I've been focusing very heavily on the e-mail newsletters which are continuing to grow like crazy! :-) I hope to get back into blogging more soon.

Matz on Ruby 2.0
Matz spoke about Ruby 2.0 ('the happiest release ever') for 30 minutes at the Heroku Waza event a week ago and the video is already available to watch. He stresses that "Ruby 1.8 will die soon" and encourages everyone to upgrade.

Aaron 'tenderlove' Patterson says that "depending on your app, using define_method is faster on boot, consumes less memory, and probably doesn’t signigicantly impact performance" compared to eval-based techniques. (And he has the numbers to prove it.)
