125 days until lockdown

Starting September 2026, a silent update, nonconsensually pushed by Google, will block every Android app whose developer hasn't registered with Google, signed their contract, paid up, and handed over government ID.

Every app and every device, worldwide, with no opt-out.

Second Life was there many years before The Metaverse (as presented by the tech bros) and is still here now it's dead

And I think that's beautiful

Factory Kit is releasing on Friday, it'll contain 130+ models including animations 🏭

As always, it'll be completely free for everyone to use in any sort of game using any engine - total freedom.

Look what I found today! It's Martin Newell's 1975 dissertation on procedural modeling, with the first appearance of the Utah teapot! 🧵

Turning a trick into a technique

A technique is a trick that works twice. Finding a new use for the even function series trick.

There were uncountable books in the library, none of which I knew. I picked one at random and read the blurb.

"A cosy fantasy?"

"Yes," said my host.

I picked another. "Cosy mystery?"

"Yes."

"Are all your books cosy?"

Cthulhu shrugged. "If you'd seen what I've seen, you'd want comfort too."

I've often wondered why audio dramas in particular tend to be such a good medium for horror and science fiction in particular, and I think it's the combination of being extremely immersive and leaving a lot to the imagination. Welcome to Night Vale is a perfect example cus I'm having trouble visualizing what Night Vale might look like, even after seeing loads of more and less official artwork, but I feel like I have a sense for what Night Vale feels like to be in.

I've just received my second revision of an ESP32-C3 prototyping board, and I've fixed an issue in my first board, which had a short circuit across the RXD and TXD pins. I've also added a CP2102N chip to connect to USB. Also, I've tried to add two buttons for pulling BOOT and RESET pins low. The buttons don't work, but I can pull the pins low manually for now.

When I try to program the chip, the CP2102N shows up as a USB device in my Linux system, but it still won't program the ESP32-C3, so I'm facing a debugging problem that I haven't yet solved.

I notice that the board is only drawing 10mA, and it makes me think it might not be booting up at all. When I pull EN pin low, current draw goes to 0mA, which is good.

I'm wondering if the 40MHz crystal is oscillating correctly, but I'm not sure if I even have the tools to measure it. When I put my 100MHz digital oscilloscope probe against the crystal, it shows a flat line around 1V. Reading the design guidelines for the ESP32-C3, it requires an oscillation of at least 500mV, which I'm definitely not seeing on my scope. Also, when I look at the datasheet for the crystal, it doesn't show such a "minimal oscillation voltage" statistic.

I can't find a recommended crystal part number anywhere, so I chose this crystal: ECS-400-10-37B2-CKY-TR

I'm trying to follow these hardware design notes for the ESP32-C3 hardware: https://docs.espressif.com/projects/esp-hardware-design-guidelines/en/latest/esp32c3/schematic-checklist.html#clock-source

Any ideas?
