I have published the snippet of code that implements a GPU-based ISP with bunch of corrections and encodes video in real time on the Librem 5. Feel free to take parts of it and use in your apps and frameworks... or record your cats 😼

One more thing to note is that DCP-o-matic's Encode Server just worked flawlessly - you simply launch it on another computer in the network and it automatically participates in ongoing encoding. Turns out that Steam Deck is the most powerful PC we own, as its participation has sped the process up considerably 😆

This NYT quote about “AI” in 80s Pac-Man is comically bad.
But rather than dwelling on that, the way the ghosts work to make it feel like they were “thinking” is a really cool example of the exact opposite. It's a series of really simple deterministic rules:
Take a few things happening in parallel in a highly specified way, throw in a little randomness (no more complicated than rolling dice), and we start assigning agency to the ghosts in the game.
This happens because 1) our brains love to anthropomorphize, and 2) we don't perceive the rules immediately.
And that's today's AI in a nutshell… More simple rules, more rolling dice—just massively scaled up!
Now you can do 10,000x more in the same time, so the result is again indistinguishable from magic, and we trick ourselves into assigning agency and even “intelligence” to the outputs.
(“Understanding Pac-Man Ghost Behavior” is a favorite article from some years ago, so it's fun to have an excuse to share it again. My thanks to the author and his original sources; most of the originals seem to be offline, but thank god for archive.org…)

Just opened my new shop with magical botanical and mushroomy items :)
If you're near Los Angeles County next week, I invite you to visit Long Beach and attend DIY Film Fest, where @holypangolin's short "The Flight of the Quirky Owl" is going to be screened on Sat, Aug 9th ☺️ https://www.diyfilmfest.life/
However, DCP-o-matic had troubles with our slightly unusual source material (variable frame rate stop-motion). The video was blinking.
So I looked into its source code and it turned out that hacking it into duplicating missing frames instead of injecting black ones was a matter of a single line change.
Now try fixing a thing like that when your Adobe suite is acting up 😂
A film festival has asked to provide the video to screen in a cinema-specific format (DCP), "created using a reliable tool e.g., DCP-o-matic".
Deadline: two days 😱
My first thought: great, I'm going to spend two days wrestling with Wine and some barely working "industry standard" tooling, am I?
But looking closer, it turned out:
- DCP is a stream of JPEG2000 frames in MXF container and some XML metadata 🤔
- the cinema expects a ext2-formatted drive 😮
- DCP-o-matic is GPLv2+ and multiplatform 🤩

@janvlug Can be much nicer as long as you don't care about the framerate 😂 #shotonlibrem5

We obtained a mysterious box of 1960s electronics. I reverse-engineered it and with much effort, we got it running. It turns out to be a test unit for testing NASA's Up-Data Link, a system from the Apollo moon landing to control the spacecraft from the ground. Let's take a look inside... 1/n

uint8x16_t vector1 = ((uint8x16_t){1} > (uint8x16_t){0}) >> 7;
printf("%d\n", vector1[0]); // 1 in clang, 255 in gcc
uint8x16_t vector2 = (uint8x16_t){1} > (uint8x16_t){0};
vector2 = vector2 >> 7;
printf("%d\n", vector2[0]); // 1 in both gcc and clang

Aren't you glad that sfghefaes (@dawlkjr27898) has added you to a group conversation on Twitter?
#StopKillingGames is about to reach its millionth signature as we speak, a month before the deadline. A tiny, but very necessary step in the right direction.
If you hurry it may be yours 😁 https://eci.ec.europa.eu/045/public/#/screen/home
