RubyConf 2021 - Ruby Archaeology by Nick Schwaderer

IN 2009 _WHY TWEETED: "PROGRAMMING IS RATHER THANKLESS. YOU SEE YOUR WORKS BECOME REPLACED BY SUPERIOR WORKS IN A YEAR. UNABLE TO RUN AT ALL IN A FEW MORE." I take this as a call to action to run old code. In this talk we dig, together, through historical Ruby. We will have fun excavating interesting gems from the past. Further, I will answer the following questions: What code greater than 12 years old still runs in Ruby 3.0? What idioms have changed? And for the brave: how can you set up an environment to run Ruby 1.8 code from ~2008 on a modern machine? **Filmed by Colorado Union Videographers
