You always wished you could have a language that explains perfectly what you are trying to do? You find yourself constantly waiting for your favorite programming language to add a feature? Why not doing it yourself? Come at this workshop and try making your own language using Racket, the language-oriented programming language! (did I say "language" twice?) This workshop will quickly describe how to use the Racket language, then dive into making your own language. I should be able to handle between 3 to 5 people at a time. Session duration should range from 1 hour to 1.5 hours.
