I, for one, would like to be able to re-grow a finger if necessary

This gif is in no way accurate but I had fun making it in Midjourney.

Scientists have taken a surprising step toward unlocking regeneration in mammals, showing that the ability to rebuild complex body parts may not be lost after all—it may simply be switched off. Using a two-stage treatment, researchers redirected the body’s normal healing response away from scar formation and toward regrowth, successfully restoring bone, joints, ligaments, and tendons after amputation in animal studies.

What you gonna do, Luke Skywalker?

AI summary

Anthropic now requires government-issued ID for some Claude features, using Peter Thiel-backed Persona. The author worries this could enable nationalist or fascistic export controls on AI usage. They outline three responses: comply with obfuscation, run everything locally, or join a cooperative compute network.

On existential cringe as a personal/professional motivator

AI summary

Personal reflection on avoiding "cringe" due to upbringing gives way to the realization that leaning into activities perceived as cringey, such as bird identification, can unlock personal and professional growth. Drawing on Cate Hall's concept, the note argues that existential cringe signals where the most progress can be made, and that freeing oneself from the fear of being cringe is creatively and motivationally valuable.

Thought for 2,682,000,000s

AI summary

The author reflects on the phrase "Thought for 2,682,000,000s" and notes it would make a fitting epitaph on their tombstone. They used AI imagery for this note, which they rarely do, because the opportunity was too good to pass up.

Intelligent companions

If you find an intelligent companion, a wise and well-behaved person going the same way as yourself, then go along with him, overcoming all dangers, pleased at heart and mindful.

But if you do not find an intelligent companion, a wise and well-behaved person going the same way as yourself, then go on your way alone, like a king abandoning a conquered kingdom, or like a great elephant in the deep forest.

Events shortlist: June 2026 to February 2027

I've decided that I want to go to more in-person events, so I got my Little Robot Friend to come up with some options.


English-language, European (or noted otherwise), aligned with digital sovereignty, decentralised and federated systems, open education, digital credentials, systems thinking, co-ops and the commons. Wildcards and strong fits are labelled.

The term "AI slop" is sloppy

AI summary

The note argues that the term "AI slop" is imprecise and unproductive, as it conflates distinct phenomena and shifts blame onto technology rather than the societal structures that enable low-quality content. It agrees with Manoel Horta Ribeiro that critiques should be more specific, noting that many pre-AI content forms already exhibited similar traits like superficial competence and mass producibility.

An AI (compute) cooperative

AI summary

co/core is a cooperative where people share their own compute power to run AI for each other, instead of renting from large providers. The key innovation is an open standard for making inference requests and recording job results, allowing anyone to build their own exchange on top of it. This idea mirrors an earlier attempt to create a shared resource platform through WebRTC.

It emphasizes setting small monthly goals aligned with those values and measuring daily progress, noting that values are what ultimately matter given life's inevitable end.

It turns out that things change, and not always for the better

I received an email from Flickr this morning notifying me that someone had favourites one of my images. It was a photo of an adult member of my family, but I was still a bit shocked.

Which is weird, because had that happened 10, 15, or 20 years ago I wouldn't have batted an eyelid. It's been quite a while since I marked all of the photos of my kids as private on Flickr, but I spent time this morning ensuring that photos including other family members are now private.

The airpod bubble

AI summary

Headphones like AirPods create a personal "bubble" that can be comforting but also isolating, reducing spontaneous social interactions and increasing loneliness. Research indicates heavy headphone use makes people feel lonelier and less likely to engage in meaningful conversations, while also causing listeners to perceive audio content as more intimate and persuasive.

Watching a game simulation to understand what my AI agents are up to

AI summary

The note describes using PixelLab to create a real-time strategy game-like visualization of AI agents (Claude Code/OpenCode) working, displayed on an iPad connected to a Mac Studio. This setup allows the user to monitor agent status and see when attention is needed, which is less distracting than watching raw text. The project is based on the "Age of Agents" repository.

Google introduces v0.1 of the Open Knowledge Format

AI summary

Google introduced v0.1 of the Open Knowledge Format (OKF), a standard that represents knowledge as a directory of markdown files with YAML frontmatter and a minimal set of conventions for interoperability. OKF is minimally opinionated, separates knowledge producers from consumers, and is not tied to any platform or proprietary system. The author found it a natural fit for their Substrate tool and implemented support immediately.

Weird, but apparently it works?

AI summary

Apple's Vehicle Motion Cues, introduced in 2024, use the device's accelerometer and gyroscope to display moving dots on the screen that correspond to the vehicle's motion, reducing or eliminating motion sickness. The feature is designed to resolve the sensory conflict between a static display and the inner ear's detection of movement.

Dead Economy Theory

AI summary

Cory Doctorow argues that Elon Musk's wealth has grown despite his failures since 2020, driven by memes and vibes rather than productivity. The true "dead economy" risk is that capital shifts from productive activities into memestocks, vibes, and bubbles, exemplified by defunding cancer research to build data centers for Musk's benefit. This misallocation threatens to create an economy that harms everyone.
