GitHub - lf-araujo/workbenchless: Single-file Emacs configuration for a powerful scientific Notebook system that works flawlessly over ssh.
"A Notebook system based on Emacs borrowing from existing config files. This system works from a single org file as an attempt to be as easy as possible for non-emacs users. It handles analyses in any language supported by org and through any server with a ssh interface. Since, its contents (an org file) are automatically rendered in Github or similar, it is trivial to share analyses results with reviewers and auditors, thus providing a way for transparent review/auditing of statistical analyses. This configuration provides a more complete set of functionality than jupyter, with less hassle."Fri Feb 7 14:26:50 2025 - permalink -

The Ramanujan Machine
The Ramanujan Machine project is an artificial intelligence project that specializes in automated conjecture generation in number theory. The project was described in detail in the paper "Generating conjectures on fundamental constants with the Ramanujan Machine" by Gal Raayoni, Shahar Gottlieb, Yahel Manor, George Pisha, Yoav Harris, Uri Mendlovic, Doron Haviv, Yaron Hadad, and Ido Kaminer. The paper, which appeared in Nature in 2021, gives several examples of automatically generated Ramanujan-style conjectures. https://www.ramanujanmachine.com/Tue Jan 28 23:19:59 2025 - permalink -- https://apieceofthepi.substack.com/p/the-ramanujan-machine
