“Simplicity is a great virtue but it requires hard work to achieve it and education to appreciate it. And to make matters worse: complexity sells better.” — Edsger W. Dijkstra The accepted “lightweight” solution is nearly 20,000 lines of code and depends on both CoffeeScript and Lua. What if you could trade all of that … Read more
