Happy Holidays from Heroku. Congratulations to the ruby-core team on a successful 2.3.0 release, which is now available on Heroku -- you can learn more about Ruby on Heroku at heroku.com/ruby. We had the pleasure of speaking with Matz (Yukihiro Matsumoto), the creator of Ruby and Chief Ruby Architect at Heroku, about the release.

What’s New in Ruby 2.3: Interview with Matz

Ruby releases happen every year on Christmas day. Why Christmas?

Ruby was originally my pet project, my side project. So releases usually happened during my holiday time. Now, it’s a tradition. It’s ruby-core’s gift to the Ruby community.

Do you have any favorite features coming in Ruby 2.3?

I’m excited about the...

This article introduces incremental garbage collection (GC) which has been introduced in Ruby 2.2. We call this algorithm RincGC. RincGC achieves short GC pause times compared to Ruby 2.1.

Debugging a large codebase is hard. Ruby makes debugging easier by exposing method metadata and caller stack inside Ruby's own process. Recently in Ruby 2.2.0 this meta inspection got another useful feature by exposing super method metadata. In this post we will look at how this information can be used to debug and why it needed to be added.

We’re very excited that our Heroku colleagues Matz, Nobu and Ko1 will all be visiting from Japan soon to attend RubyConf, and it’s especially serendipitous that it is happening in such close proximity to Thanksgiving. Not only is Thanksgiving one of the few holidays that Japan and the U.S. share, it’s a holiday that brings families together to reflect on what’s been accomplished, and to share insight into the future. We've been waiting for just the right opportunity to organize a small Ruby gathering and Thanksgiving provides the perfect setting.

"I hope to see Ruby help every programmer in the world to be productive, to enjoy programming, and to be happy. That is the primary...

When we think of the concept of Waza (技) or "art and technique," it's easy to get caught up in the idea of individual mastery. It's true that works of art are often created by those with great skill, but acquiring that skill is neither solitary nor static. Generations of masters contribute to a canon and it is in that spirit that we built the Heroku platform and the Waza event. This year's Waza was no exception.

On February 28th, more than 900 attendees participated in Waza including Ruby founder Yukihiro "Matz" Matsumoto, Django co-creator Jacob Kaplan-Moss and Codeacademy’s Linda Liukas. True to form, we offered you a platform for experimentation and...
