Yes I know — Java, ick. But sometimes it’s worth it. Even though JRuby is blazingly fast, sometimes as fast as Java, there are situations where it just makes more sense to roll up your sleeves and write some proper curly brackets.
Until very recently I wasn’t aware that JRuby had any form of extension API, I just thought that because the Java integration is as good as it is out of the box there wasn’t any need for something like the MRI C API. Then I came across Charles Nutter’s Atomic gem, which is partly written in Java, and had some curious properties that made me dig a little deeper.
