We're happy to say that we recently released the code for the TraceView Ruby instrumentation on Github as Open Source. There are a ton of benefits for AppNeta (and the community) in doing this so making the decision was easy... but the process of actually opening the repository and still keeping a few things private was slightly trickier.
