We started this from a vague dream with @adrianhill.de, and reached 1000 dependents and 100k downloads last month. Research != just papers.

Remember to follow the official rebuttal guide.

A 26-panel infographic titled “A to Z of How to Write a NeurIPS Rebuttal,” with each panel representing a letter of the alphabet and a corresponding step or emotion. The top-left panels (A to D) show calm, professional cartoon characters with labels like “Acknowledge,” “Be concise,” “Clarify,” and “Dispute.” As the panels progress, the characters grow increasingly stressed, disheveled, and wild-eyed. Midway through, with panels like “Justify choices,” “Keep calm,” and “Obsess,” the illustrations become more chaotic and colorful. Toward the end (letters U to Z), the images turn black and white, depicting characters with frantic, exaggerated expressions, culminating in “Zombie.” The visual style shifts from clean and organized to frenetic and distorted, representing the mental unraveling of a researcher under rebuttal pressure.

Yes, the interoperability between Julia and many other languages is amazing! I often work in the other direction, calling for example these from within Julia code: - R (github.com/JuliaInterop...) - Python (github.com/JuliaPy/PyCa...) - Matlab (github.com/JuliaInterop...) from Julia. #julialang

RCall.jl is really useful. Take any function that you like from R and turn into a Julia function without any hassle. I use this a lot when benchmarking my research coded in Julia with established methods in R.
