12:16a	[$] An introduction to Pluto Pluto is a new computational notebook for the Julia programming language. Computational notebooks are a way to program inside of a web browser, storing code, annotations, and output, including graphics, in a single place. They became popular with the advent of the Jupyter notebook, which originally targeted Julia, Python, and R—the names got mashed together to make the word "Jupyter". (Comment on this)

It also aims to bridge all of the different chat mechanisms that people are using in order to provide a unified interface for all of them. (Comment on this)
