Procedural Textures with Hash Functions and Hash Playground I'm the sort of person who gets very excited when simple rules create complex behaviour. The other day, I needed a simple hash function that maps $(x, y)$ coordinates to a colour, and found a straightforward equation that ended up being astoundingly rich. Hence this post; to talk about and play with this function. TL;DR: The boolean predicate $(c_x \, x + c_y \, y + c_{xy} \, x \, y + c_{x^2} \, x^2 + c_{y^2} \, y^2)$ $\mathrm{mod} \

K(r)ep - A high-performance string search utility krep is an optimized string search utility designed for maximum throughput and efficiency when processing large files and directories. It is built with performance in mind, offering multiple search algorithms and SIMD acceleration when available. Note: Krep is not intended to be a full replacement or direct competitor to feature-rich tools like grep or ripgrep . Instead, it aims to be a minimal, efficient, and pragmatic tool focused on speed a

Exploring LispE: A Distinctive Take on Lisp Through Pattern Matching and Logic LispE, a modern Lisp dialect developed by Naver, introduces innovative constructs— defpat , defmacro , and defpred —that set it apart from traditional Lisp implementations like Common Lisp, Scheme, and Clojure. While Lisp dialects share a heritage of flexibility and macro systems, LispE extends this with advanced pattern matching, enhanced macro capabilities, and logic programming elements.

Even the tiniest of living things are capable of some amazing forms of locomotion, and some come with highly sophisticated sensor suites and manage to source their energy from the environment. Attempts to approach this sort of flexibility with robotics have taken two forms. One involves making tiny robots modeled on animal behavior. The other involves converting a living creature into a robot. So far, either approach has involved giving up a lot. You're either only implementing a few of life's f

I remember thinking at school when will I ever in my “real life” use maths. Well much to my utter surprise I’ve come to the stark realisation that there is a link between mathematics and crochet. Yes its true… In fact, crochet patterns have an underlying mathematical structure — the pattern created by the regular presence or omission of stitches is the very essence of this art form. The similarities to Base2 math, with its series of 0s and 1s, are obvious. That is to say, a present stitch is lik

In context: Making robots more biologically compatible has been a challenge scientists have been tackling for years. Until now, they have primarily been able to create lab-grown muscle fibers that contract along only one plane. That works well for a robotic arm that bends at a single joint, but it falls short when it comes to more complex movements. In contrast, the human body's muscles are far more versatile thanks to fibers arranged in intricate, crisscrossing patterns. Now, MIT engineers hav
