People read this? That's cool.

I make code things that draw things. I try hard not to build on top of quicksand. Not a big fan of jerks.

rezmason··on The Art of Dithering and Retro Shading for the Web (2024)
The article's author, this Maxime Heckel, has got an excellent online portfolio of shader work! https://maximeheckel.com

Oh, no. The machines have come to take my job.
rezmason··on Apple's macOS Unix certification is a lie
In case it bears mentioning, the rationale behind this was that the migration from Mac OS 9 to Mac OS X was complex, and needed to be justified. Establishing OS X as more stable than Mac OS 9 was an important argument for that push.

"Mac OS X is more stable!"

"How stable is it?"

"Well, it's built on top of an established workhorse or something you've never heard of!"

"Gosh! Take my $129!"

rezmason··on Halliday AR(Not?)/AI Glasses
I'd pair a pair of Halliday glasses like these with a pair of bone induction headphones. That oughta do it.

Wireless connectivity/latency issues aside, we're probably better off with them being two separate "cranium accessories" (as Mitch Hedberg called them), to accommodate a wide variety of heads

rezmason··on Oliver Heaviside and the theory of transmission lines (2021)
There's a fascinating story about ego in science buried here.

William Henry Preece was Engineer-In-Chief at the British Post Office in the late 19th Century (basically heading their telegraphy efforts) and controversially stuck to Thomson's model, or the "KR Law" as it was called back then, relying on poor quality experimental results to direct the organization.

Oliver Heaviside publicly criticized Preece, who in turn blocked publication of Heaviside's writing to preserve his own reputation (according to Wikipedia). When Preece retired in 1899 and received a knighthood, Heaviside wrote in the preface of Volume II of "Electromagnetic Theory":

"It is to be hoped and expected that the late important removals in the British Telegraph Department will lead to much improvement in the quality of official science."

Writing by hand on his own copy, Heaviside suggested that the preface (and thus the book's publication) were "held back" so as to "allow W H Preece to make sure of his knighthood".

So! On the one hand, we have an esteemed engineer who ran the country's telegraphs and refused to admit he made a mistake, became a knight and faded somewhat from history; on the other hand, we have a self-taught physicist who made massive contributions to our understanding and analysis of electromagnetism, lived in "relative poverty" for fifty years while doing so, didn't shy away from calling out bad science, and he gets the analogue of heaven named after him in the musical "CATS".

rezmason··on Hard numbers in the Wayland vs. X11 input latency discussion
This reminds me of the early work of the structuralists in psychology. Measuring the time it takes for a person (or in this case Wayland) to react to a sensation.

rezmason··on How corn syrup took over America
Disclaimer: I'm not an allergist or nutritionist, I only know my personal experience.

I would consider myself over my allergy. I'd say it lasted seven years, gradually diminishing in severity over time.

For the first couple years following the diagnosis my parents had me eating spelt, kamut, quinoa and all that. Alternative recipe books, bag lunch, Martin's potato bread, health food store, no vending machines, no trick or treat candy, and we checked the ingredients on every box. But like you said, HFCS is practically unavoidable. My parents made some judgment calls— they checked my reaction to corn starch and plain old corn, and I had none. The alternative grains went away, we were just ingredient checking and keeping my corn intake relatively low. Five years in, I was eating the same stuff other kids ate as long as it wasn't sugary like pancake syrup or a cinnamon bun. Then after puberty corn syrup was the bad grade scapegoat and nothing more.

Nowadays I will demolish a bowl of Honey Comb cereal— basically corn flour hexagons. I read the nutrition facts and ignore the ingredients list; my childhood allergy doesn't even enter my mind. Arrowhead Mills spelt flakes are delicious, though.

Your sister's a completely different jumble of molecules, and my experience might not apply, but I would recommend a similar approach my family took: switch to boring food for a year or two, even in the tricky social situations surrounding food. Then, talk to the allergist (or don't) about safely testing subcategories of corn product. The worst offenders are probably the sweeteners. I hope corn flour makes it back on her menu, but if not, I imagine now is a great time to be allergic and on the Internet.

rezmason··on How corn syrup took over America
Breaking out in hives, mostly. Throwing up a couple times. I forget how we determined it was maltodextrin, but for the first year I was also off wheat and milk while they worked it out.

I was raised with an allergy to this stuff. Now I eat it for breakfast and observe its birefringence between two polarizers.
rezmason··on Microsoft Bob: Microsoft's biggest flop of the 1990s
Let's use the clickbait title as a brainstorming prompt: what do other folks think is a better candidate for the biggest flop [in tech] of the 1990s?

Also, I kind of wish Microsoft Bob failed a little harder— the agentic stuff I'm hearing about these days sounds like the kind of software assistants they tried in the 90s, and I fear they have the same likelihood of poor execution.

rezmason··on Microsoft Bob: Microsoft's biggest flop of the 1990s
Does anyone know of a paradigm original to Microsoft Bob that survived? Other than Rover the Windows XP search dog.

rezmason··on “PET-Globe” Demo
96x32 pixels? A kindred spirit!

I'm using WebGL to emulate a unique Casio LCD that hue-shifts pixels into the right color, and its display is 95x32 and typically its bit depth is two. (The hardware is 96x32, I'm honestly not sure where the last column went)

Before long I'll want to display more interesting things on it; OP, can I try to credit your project and port it to JavaScript for my LCD emulator?

rezmason··on Stopping by Woods on a Snowy Evening (1923)
Some say the world should take cyanocobalamin,

Some say methylcobalamin.

From what I’ve tasted of each vitamin

I hold with those who favor cyanocobalamin.

But if my supplement could have a twin,

I think I know enough of niacin

To say that for nutrition methylcobalamin

Is also great

And would fit in.

rezmason··on A data table thousands of years old (2020)
For years I've wondered what the first, earliest color lookup table was.

Like any mapping from an index to a color value. Like a design for a Roman mosaic that indexes tesserae, or a declaration of which parts of a statue or mural would receive which color paint. Or even the inventory of someone who traded in pigments.

rezmason··on There Are No More Dogs in Antarctica
Good points!

I think I'm just coming to terms (in a public forum) with the bleak fates of animals that humans transport, ie. to the ends of the Earth.

rezmason··on There Are No More Dogs in Antarctica
So it was practical at one point to dogsled around Antarctica, and it was practical to leave there any dogs who perished.

Did this apply to both polar regions? Is the Arctic one enormous, 35,000-year-old frozen pet cemetery?

Edit: come to think of it, this applies to humans too, at both poles.

rezmason··on An 83-year-old short story by Borges portends a bleak future for the internet
We're two comments in and this is, so far, the most extensive conversation about a good Borges story I've had in my life, so kudos for that :)
rezmason··on An 83-year-old short story by Borges portends a bleak future for the internet
I think a more apt Borges story is 'Tlön, Uqbar, Orbis Tertius'— where a clandestine guild creates artifacts from a fictional world with the intent to deceive. The artifacts and the world they allude to carry such appeal to the masses, that they essentially trump the rest of society as a source of truth and annihilate all culture that came before.
rezmason··on Goodbye, Rust. I wish you success but I'm back to C++ (sorry, it is a rant)
> You'll find people on HN arguing

No I won't!!

Sorry.

rezmason··on Goodbye, Rust. I wish you success but I'm back to C++ (sorry, it is a rant)
I don't think the goal of Rust has to be to unseat C++, just like the goal of Macs is no longer to unseat Windows. Here are some nobler goals:

* be a language that users and non-users believe is better

* be a language that people learn things in before entering the industry

* be a language for solving important problems, if not every problem

* if a billionaire buys C++ and makes it terrible, be an alternative

Edit: unrelated— I really struggle with writing lists on HN. :-(

rezmason··on The Art and Mathematics of Genji-Ko
Great post, OWL! I love a good mathematical diversion with cultural context wrapped around it, it's like a beef wellington for the analytical mind.

Codepen is great for discourse like this but I want to put the conventional Genji-mon in a unit test and then go hog wild with rule construction, because I remember running out of steam exploring more robust rules that still satisfy `width` = 5.

I'm bearish on LLMs, for better or worse, but you seem to know your way around them. Do you suppose this problem could be attacked with some sort of trained rigmarole that writes rulesets?

rezmason··on The Art and Mathematics of Genji-Ko
A couple years ago I made a codepen to generate arbitrarily long Genji-mon from a ruleset, and managed to write a rule that reduces the number of required special cases to one. However, these rules are very fragile, and "break" with lengths > 5 (edit: or maybe they don't! this deserves further exploration). Glad to see someone else discovering the structure behind this interesting system!
