Now that I know how to add quick dither to stuff, you can be sure that I'll use it everywhere. The magic uxn opcode is EOR2k(non destructive XOR2 on the x,y position)

@neauoire I feel like that poor lady didn't ask for her eyeball to be licked.

@neauoire Is it some Maruo's work (the art) or some other very good artist?

I have a little hole in the wall library next to the nav station where I keep some personal favourites that I like to re-read.

@neauoire .. That Spirals comic. That Ito guy. So ridiculous.

Since it's unlikely that I'll complete my current reading before the year's end. Here's this year's reading catalog, it was a fantastic year, read some of my favourite readings ever.

My absolute highlight has also been the first reading of the year, Maurice Renard's The Blue Peril.

@neauoire Belle liste!
Et dans les non-fictions, quel est ton highlight?

Kototama

@neauoire put "la horde du contrevent" in incoming :) don't read much about it, to avoid spoiler, just read the first chapter and you will probably be hooked

@neauoire Oh, you read The Tartar Steppe. Did you like it ?

After learning the neat trick to approximate distances without square root, I wanted to see if I could automate stroke thickness in oekaki for more natural brush-like lines.

Still poking at natural brush dynamics, flipping the values gives either the effect that the pen's ink is thinning and pooling at the corners, or that pressure is increased on longer strokes. This drawing tool packs a lot of fun for 4000 bytes.

@sorenpeter I noticed you removed the webring icon from your website, I'll remove your site from the list, you're welcome to open a new PR if you'd like to rejoin :)

@neauoire these are reminding me of an awesome old computer game I played as a kid on my cousin’s fruity iMac. I had to do some googling, but I found it! It was called “Thinkin’ Things 2” where you could create kinetic pictures looping with music. I was addicted to playing with all of the tools and flipping through their examples.

@neauoire the funky christmassy hyperworms from outer space are here to take over the world, never stop doing them! 🥰

I keep reading blogs of people who are "I don't know what I would do without language models", or "Every part of my daily life has been impacted by AI", and I wonder how? I mean, I've opened midjourney once when it came out and asked it to make some ridiculous thing, and then I tried chatgpt and it answered some nonsense. But is there an angle where it's just part of people's everyday life that I'm totally oblivious to? What do people even use llms for, surely it's more than chatbots no?

@neauoire it's larping the scifi AI future that they assume vN+1 will be

@neauoire I use it sometimes like Google, I don't bother to say "Hello" or "Thank you" to a machine. I just put in "linux function timing in ms" and it gives me C code. Sometimes it doesn't understand you or is wrong, not a magic bullet for sure.

@neauoire its like a programming interface that uses natural language to code and debug programs, lines of thought and large data sets. You can do anything with it.
I use it all the time for coding. There is zero reason to trawl through poor documentation where all you want is to describe a human readable way to do things that the machine can translate into actual code, help you reason through it and debug it. It's an incredible learning tool and I wouldn't go back to a world without it.

Thanks for all the report from mastodon.world, a couple more and we'll silence the instance for a bit while they deal with it.

Someone taught me how to approx distance between two points without sqrt.

max(abs(x),abs(y)) + min(abs(x),abs(y))/2

@neauoire Nifty! I've been doing an approximate `sqrt(n)` recently with this iterative approach:
a = n
for 1..m:
a = (a + n / a) / 2

So I tried this using your approach for an initial guess:
a = max(abs(x),abs(y)) + min(abs(x),abs(y))/2;
s = x*x + y*y;
if (a != 0.0) {
a = (a + s / a) / 2;
a = (a + s / a) / 2;
}

Within a range of -100 to 100 this takes your approximation from a max error of about 34% to a max error of 0.4%. The average error goes from 9% to 0.4%.

It's still just 7% max error and 0.4% average error if you only do one iteration.

Sorry, no fancy visualisations, but here’s a picture of them both overlayed (I considered a “they're the same picture" meme instead):

@neauoire Things I’d wish I’d known 30 years ago..

I've come to associate this time of year to hanging with friends on their cozy wooden boat drinking mulled wine and playing card games.

For today's #lovebytetcc, I made it so the snow accumulates on the tree in 450 bytes. It's fun to revisit these challenges with more familiarity with the #uxn ecosystem.

@neauoire perhaps a naive question, but are there any up to date guides to getting/using uxn. Say, with the new OS additions. I felt foolish the other day, wasn’t sure which repo to clone or how to really start

Lovebyte Demoparty

@neauoire I remember sitting in front of the computer as a kid (with no real skills whatsoever, just getting those first pixels to who up) wondering how the heck you'd get snowy pixels to accumulate... if will always feels like a magical thing to me! 😍

I realize that there's spam from .social going on, if this goes on for longer I'll silence the instance for a few days while they get their shit sorted.

@neauoire that’s annoying, i really hope it’s stop soon.

@neauoire got a spam ping from there today, seems they’re being raided or something. Props to the message being gone by the time i opened the notification though
