Rhizome Function Anagram Random Generator

preprint | https://zenodo.org/records/21551292

doi | https://orcid.org/0009-0009-5144-3278

Herein are described principles and a scheme of random number generation styled as, pangrandomonium, or ‘pangrand’. Pangrand is a anagrammatic random number generator that uses rhizome functions as chaotic indexing and shuffling instructions to reorder and sum perfect pangrams. Brief descriptions are given for the principles of pangram summing and rhizome indexing functions, Source code of the random number generator is included herewith. The source code is attached to the PDF file.

Sections:

1. Pangrams (Holoalphabetic arrays) ;
2. Rhizome Functions ;
3. Rhizome Hardness Problems ;
4. Random Generator Methods ;
5. Errata ;
6. Source Code.

The man whose codebreaking may have helped to shorten the Second World War by two years met a grim reward: in 1952 Alan Turing was convicted simply for being gay and chemically castrated; a royal pardon came only in 2013, decades after his death

Pixel: a biography

An exact mathematical concept, pixels are the elementary particles of pictures, based on a subtle unpacking of infinity

A pixel does not need to be rendered as a small square. This image shows alternative ways of reconstructing an image from a set of pixel values, using dots, lines, or smooth filtering. Three panels showing image reconstruction/rendering at increasing resolution: (left) a coarse dotted/pixelated pattern of a "Z"-like shape, (middle) a finer striped/dithered version, (right) a smooth, high-resolution photo-like curve — illustrating progressive image reconstruction from low to high pixel density.

Happy Birthday, Richard E. Stearns! Stearns received the 1993 #ACMTuringAward with Juris Hartmanis in recognition of their seminal paper which established the foundations for the field of computational complexity theory.

In this video, Stearns describes how he and Harmanis discovered the breakthroughs that contributed to their paper. The full video is here: https://youtu.be/Z-Ek0CCThZQ?si=3N5QU1RNmNqJb8ia

#ComputerScience #computationalcomplexity #TuringAward

On this day in 1913, Maurice V. Wilkes was born. Wilkes is best known as the builder and designer of the EDSAC, the first computer with an internally stored program. He received the 1967 #ACMTuringAward for his many contributions to the field of #computerscience: https://amturing.acm.org/award_winners/wilkes_1001395.cfm

It was an honor to host these brilliant thinkers, pioneers, and rising stars, whose work continues to shape the digital landscape and improve lives globally.

We extend our deepest gratitude to all the laureates for their dedication, to our community for its enduring support, and to everyone who joined us to make this weekend’s celebration so memorable.

The 2026 ACM Fellows

Happy Birthday to Alonzo Church. Born on June 14, 1903, Church helped establish the mathematical foundations of computer science through his work on lambda calculus, computability, and the Church–Turing thesis. His ideas continue to influence programming languages, algorithms, and our understanding of what computers can and cannot do.

React-like syntax with WebComponents.

​After spending some time with Lit, I really appreciated its lightweight footprint but wasn't a fan of the class-based components. While Vue offers a great approach, I still prefer the intuitive nature of React's syntax for debugging and deterministic rendering. This led me to a challenge: could I build a UI framework using WebComponents that completely eliminates the need for transpilation?

​I have written a breakdown of the concept, the architecture, and where I want to take it. I highly invite you to take a look, check out the code, and explore the live demo.

* How it works: https://positive-intentions.com/docs/projects/dim/dim-jsx-webcomponents
* Checkout the code: https://github.com/positive-intentions/dim
* Storybook demo: https://dim.positive-intentions.com

​Please note, while the project is open-source, this is a personal exploration rather than an attempt to launch "yet another framework." It is not production-ready and is built for my own upcoming project migrations, but I am sharing it in hopes that the methodology is educational or interesting to the community.

​I would love to hear your thoughts on this approach. Feel free to reach out if you have any questions or want to discuss the implementation details.
