These are my slides and my notes from a presentation on Picolisp I gave.
The presentation is called "Simplicity and minimalism in software development" and has a focus on the benefits of using a simple but powerful tool to develop programs, in contrast to the rather complicated and heavy tools in general use today.
In my view, Picolisp embodies both simplicity and minimalism in the best senses of the words and provides an important counterpoint.
