Minimalism matters in computing. Minimalism allows for smaller systems that take less resources and consume less energy. More importantly, free and open source minimalism allows for secure systems that are easy to understand. Minimalism is also educational and brings back the fun of the early days of computing where people learn to understand systems from the ground up. As a co-organizer of this devroom I will talk about my journey through many programming languages and ending up with Scheme (a minimal Lisp). Lisp is the second oldest language in use today and growing. I'll show you that once you master Lisp you can use it everywhere from software deployment, the shell, the editor and debugging and for programming systems and in the browser. As a matter of fact, Lisp is everywhere!
