A simple programming language with syntax similar to Go. Found via https://www.tuhs.org/pipermail/tuhs/2022-February/025351.html
A bit later in the same thread, the scripting language Wren https://wren.io/ was mentioned.
Some people on the 9fans mailing list critcized V in a thread starting at https://marc.info/?l=9fans&m=172789698811416&w=2

While this blog article is about a new feature of the Scheme-based Guix Linux package manager, it contans the following interesting observation about erroneous shell settings: "it’s not uncommon for the shell to mess up with the whole environment. Why? Because, contrary to documented practice, it’s quite common for users to define or override environment variables in the startup files of non-login shells, ~/.bashrc for Bash, ~/.zshrc for Zsh. Instead, environment variable definitions should go to the startup file of login shells—~/.bash_profile, ~/.profile, or similar. But let’s face it: it’s a subtle distinction that few of us know or care about."

It's not about technology for its own sake. It's about being able to implement your ideas.

TODO: https://www.johndcook.com/blog/2022/10/30/arctan-k-tan-t/ states "This plot looks similar to the plot of true anomaly for a highly elliptical orbit. I’m sure they’re related, but I haven’t worked out exactly how."

https://www.johndcook.com/blog/2022/10/21/math-origins/ explains V.I. Arnolds comment
"All mathematics is divided into three parts: cryptography (paid for by CIA, KGB and the like), hydrodynamics (supported by manufacturers of atomic submarines), and celestial mechanics (financed by military and other institutions dealing with missiles, such as NASA)."

https://www.johndcook.com/blog/2018/09/24/riemann-hypothesis-the-fine-structure-constant-and-the-todd-function/ is about  Sir Michael Atiyah's incorrect proof of Riemann's hypothesis, the article https://rjlipton.com/2018/09/26/reading-into-atiyahs-proof/ is an interesting read. (I had bookmarked this entry on Wed Sep 26 15:51:47 2018 and put it here 2024-04-03.)

The article https://www.johndcook.com/non_central_chi_square.pdf sounds interesting:
John D. Cook Upper bounds on non-central chi-squared tails and truncated normal moments (2010). UT MD Anderson Cancer Center Department of Biostatistics Working Paper Series. Working Paper 62.
Abstract. We show that moments of the truncated normal distribution provide upper bounds on the tails of the non-central chi-squared distribution, then develop upper bounds for the former.
