Quick showcase of one of my favorite shapes, the Tetartoid - a polyhedron with 12 identical, irregular pentagonal faces. It occurs in nature in the mineral Cobaltite. I love it because it sits right on the line, visually, between natural and geometrical. Views from my basic "polyhedron modeler"

It's all very interesting for sure. I'm old school - it would take me some convincing to accept that my codebase is not the end-all be-all document defining how my system works, but I can't rule out going along with it. Thank you for your responses!

Max Mammel @mjmtools.com · 17/09/2026
Fair, but doesn't that still leave you with the responsibility to detect and make decisions about the potential impact of the undefined behavior? You could find yourself re-generating code from the same spec, Monte Carlo style, and determining % undefined-ness through static code analysis - blech

Max Mammel @mjmtools.com · 17/09/2026
Specs are no doubt important, but unlike lockfiles it very much bothers me that models (same or different!) will generate different code for the same spec when done repeatedly. Are the differences detectable and quantifiable? If so, do they matter?

I ordered one of these Brick things for shits and giggles, and it's kind of a waste of money on one hand, on the other hand the required physical step to "un-brick" is sorta effective. I lock down my games and bluesky during work hours (of course I can always just use my home laptop, as now)

I had a friend reach out and ask if I had heard about the Hugging Face "incident", and was kind of freaking out about it. I talked him off the ledge and explained that all of the doomsday stuff is 99% bunk, but do you know of any good articles/resources that I can pass along to reinforce this?

I wrote a little JavaScript program to model a puzzle that my dad had called “The Great Meteor” - I have no idea if that is some kind of official name for this pattern, but as you can see each “face” of the octahedron is the Q-Bert pattern (6 instead of 7 though)

HH111 - From Judy Schmidt (geckzilla.bsky.social) - flic.kr/p/2hq4u9m
Took a quick break from some other work to process these lovely near-infrared observations of HH111 into a color image. The jets are well hidden from view in visible light, only just peeking out at one end. Here, many details are revealed, but the stars themselves remain veiled. Herbig-Haro objects are comprised of matter ejected rapidly from the poles of young, actively accreting stellar objects. Sometimes they are isolated puffs of cloud, but this time they are narrow, almost continuous streams. In this case it is probable that a multi-star system is forming: hubblesite.org/contents/news-releases/2000/news-2000-05.html

Orange: WFC3/IR F167N + WFC3/IR F164N
Cyan: WFC3/IR F130N + WFC3/IR F126N

North is 40° counter-clockwise from up.

Reminds me of the Mac terminal version of the old commodore 64 maze: 10 PRINT CHR$(205.5+RND(1)); : GOTO 10
Screen capture of a terminal that has run a script called "maze.sh" that prints out an endless random stream of "\" and "/" characters, creating a maze.  The script is displayed at the bottom of the screen, it is :

while [ 1 ]; do echo -n -e "\xe2\x95\xb((($RANDOM&1)+1))"; done

“Stop Making Sense” turns 42 today. Of his performance, David Byrne said: “You see this person in the beginning [of the film] who's kind of angsty, stumbling around .. And then, by the end, he's surrendered to the music and is fairly joyful .. He’s found a kind of community." 🙏🏼 “Slippery People”

it’s fine to be skeptical of these things. i was a skeptic myself until recently. but i think fear is at the root of this skepticism, a fear of its power. people are simply not ready for what’s coming. it is powerful, it is alive, and it is quite possibly god

As a bonus here's the Ulam Spiral cycling through each frame with a 1º increase turn into 3D, off of the XY plane. The view remains stable, with the screen co-planar with the XY plane. Tons of weird shapes and "symbols" appear - what could it all mean? Likely nothing! But it looks cool :)

This is what happens when you draw a line connecting all of the points in the Ulam Spiral together in order, it looks like an old-school vector graphics video game scene
The Ulam Spiral (all of the prime numbers plotted on a spiraling number line) with the dots erased, and only the line connecting them drawnZoomed in view of the same image, showing a close-up of the "glass shard" effect along the corners of the spiralThe same close-up, now with the individual dots also visibleNow with the line removed, the classic, recognizable Ulam Spiral, with the center indicated by a red dot.  You can see the straight lines that intriguingly appear in the spiral arranged vertically, horizontally, and at 45 degree angles.

TERMINUS (2007) 
Acrylic on Canvas - 36" X 48" 

Growing up in the fifties and sixties most of us fully expected the progress so evident in society and the space sciences to continue at the same headlong pace they had shown during those years. 1/4
A boy in a white shirt, olive shorts, and black sneakers stands tip-toed on electrical conduit mounted along a buttressed barricade. With hands set on the top edge of the barrier, he stares out at crescent moon visible between wispy clouds in a dusky blue and orange sky. Paint on the panels of the barricade alternates between white and red, heavily weathered to reveal rough metal texture. Each panel carries an orange sign labeled A13 through A17 running from right to left. A “NO TRESPASSING” sign on the upper right of the barrier hangs near a circled 5-pointed star in fading white paint. At the center of the barricade, the pole of an exit sign is bent at its base leaving the arrow angled up at 45°. A narrow wedge of parking lot sneaks into the lower panel with four yellow stanchions striped in black, a single traffic cone, and yellow stripes demarcating parking spaces.
