In this post, I share the contents of a fun mini-conference I held with my friends titled ‘C and Ruby’. I started with a brief introduction to C, then we looked into the sources of Ruby to try to understand how some basic methods, such as Array#reverse, work and to actually dive in and make (minor) changes to the Ruby core. Then we looked at implementing native extensions for ruby and some of the implications on performance, memory or ease of development.
