Lightning Talk Wrapup - November 2020

On November 2nd, 2020, we had a series of lightning talks by members of the community.

Raymond Puzio — emacs hypernotebooks

Raymond presented his notebook software that uses Emacs to bring together multiple programs to make a single set of computations. It’s able to pass data back and forth between these programs, generate results, and even output publication-quality documents. Raymond referenced a previous EmacsNYC talk Evan Misshula gave about reproducible research. Raymond will be publishing his code soon.

Adrien Brochard – emacs user survey 2020

Adrien spoke about his user survey, aimed at finding out how the community uses Emacs. You can find more information and fill it out at

Qiantan Hong – crdt.el, a collaborative environment

Quintan spoke about crdt.el, a project which enables collaboration through shared editing sessions. Check it out here. This project uses algorithms from the Conflict-free Replicated Data Types family. A talk about this can be viewed here

Qiantan Hong – reflexive-music, an experimental music environment with Emacs as frontend

Quintan presented reflexive-music, an environment to create music through code. He ended his presentation with a live concert. He was inspired by Ivan Wyshnegradsky, a Russian composer known for his microtonal compositions. Contact Quintan to encourage him to publish his code!

Zachary Kanfer – Composing Electronic Music in Emacs

Zachary presented his solution to boredom during quarantine: his software to compose looping music in Emacs. He had to dive into WAVE files to create it. Find it at

In addition to our lightning talks, there are a few announcements from members of the community.
