I had difficulty explaining Nat.below and Nat.brecOn in Section Structural Recursion and Induction of Theorem Proving in Lean 4. Sadly, I'll have to record a video of myself doing it again because my explanation missed the point. Still, I'm glad that I understood course-of-values recursion so much better than I did four years ago.

I was able to prove that the definition of the Fibonacci function, which directly uses Nat.brecOn, is equivalent to the one that doesn't.

Mozilla is adding a toggle to disable all generative "AI" features in Firefox. It shows that organized pushback is actually making a difference.

One battle won. Now let's make it crystal clear. We want tools, not forced LLMs. Keep the pressure on until "AI" is no longer an option.

the server side is also annoying because we either have to let the host be a permission owner and build a parallel system (seems bad) or just rely on oauth but then you have to sign in "into" any origin widget. which on the other hand maybe makes sense as a trust model? but annoying to fill in

Photographer Builds Mini Kodak Kiosk That Actually Prints Photos

PetaPixel | Photography and Camera News @petapixel.com@web.brid.gy

A hand holds a color photo in front of a small yellow and blue Kodak-branded photo printer on a wooden table, with window blinds in the background.

Photographer James Warner, known for his excellent YouTube channel, snappiness, is always taking on new photography projects. They often involve taking things apart and putting them back together in new, exciting ways. Warner's latest project involves building a mini retro Kodak photo printing kiosk for his desk.

mutations are kind of annoying as usual, you'd have to somehow deal with the cache between components that don't know each other and keep the behavior sensible (e.g. don't update everything all the time, but also a single thing is sometimes not what you want). mirroring +1 like counts is an example

you'd think performance is a big problem but if you make it yieldy like react, maybe it's okay? the server can memoize globally, at uris are good keys, seems like it should be possible to have mechanism like cacheTag in Next.js hooked up to the firehose? even for backlinks? seems cacheable

Sometimes I get a really good quote in.

“Pointing out that AI is prone to giving ICE bad information is missing the entire point of ICE,” EFF’s Eva Galperin told Rolling Stone. “They don’t care if the information they have is good.”

this is probably still too limiting for final bit of polish. maybe this is why it can't be a final space. so maybe it's a space for something more simplified, like "less than a product". something like skircle is a good example but maybe there could be more experimentation with those things

one difficulty is that you probably don't want to mix different third-parties' client-side behaviors, or at least i don't know how to do it safely. maybe there's some way to narrow it down. but maybe the host's built-in collection could be very expressive but entirely declarative. like good sdui

individual atproto uis are already remixing data from different apps. so the concept of an "app" blends — each product is a prism over the shared ecosystem. and if nothing except authorship is firmly gluing different pieces, could an application be glued together from different authors' pieces?
