i wonder what it would look like if blocklists were kind of voluntary. like “yeah i talk about ai” but you add yourself to it, rather than get added by someone. like a badge you wear. and you can choose to block out all people wearing some badge if you want

learned a lot doing this bugfix. types in Lean live in different "universes". you can be generic over those "universes"

This seems necessary for solving not_mem_self from 3.2. I presume it worked before but got broken by the epilogue-related changes. Test case theorem SetTheory.Set.not_mem_self (A:Set) : (A:Object) ...

that’s actually a really cool explanation (at the end of the thread)

spent ten minutes debugging why an element's border was showing underneath another element despite the latter being fully opaque. turned out it was a hair on the screen. i only noticed after i scrolled the page a bit down
claude code is giving me the courage to do things i would never do (preprocess SVG illustrations for my blog with the gnarliest regexes to slightly tweak Excalidraw's output)
lmao i'm asking claude questions about how regularity prevents russell's paradox and claude is getting so confused it asked *me* to help it untangle it
i would like a set of all sets that don't contain themselves, please
ok i didn't realize this before but it's kind of wild that in Lean, which is strongly-typed (!), the return type of a function can depend on the input values (can even be extracted to another function to be calculated). i guess that's obviously needed for proofs to work but it's still wild
want my discover to think stuff like this about accounts i top-like
Created an autogenerated list of the accounts I've liked most this past month! (Top-level posts only) Hoping this can serve as a sort of rolling starter pack for accounts I enjoy.

Slightly rework Subtype explanation by gaearon · Pull Request #145 · teorth/analysis
Continuing #143. I finally understand what's going on here and wanted to slightly rework this based on my new understanding. I think the key is to introduce concepts step by step. There's a...

Markus Himmel has written a blog post about how to write a simple imperative program in Lean and then how to verify that the program is bug-free. markushimmel.de/blog/my-firs...
My first verified (imperative) program
One of the many exciting new features in the upcoming Lean 4.22 release is a preview of the new verification infrastructure for proving properties of imperative programs. In this post, I’ll take a fir...

does claude code never "undo"? seems like as a human i often "undo to last checkpoint where things seemed to work better". would be nice to codify this without git commits
has anyone tried making agents emotional? i feel like it would be nice to have some kind of a state machine that makes it more motivated to dig into something or kind of backtrack when it gets bored, vs getting excited at chasing the solution when it feels it's close etc
ok so this is kind of very interesting. you need to actually "design" MCP tools to work well. for example the Lean one is actually getting helpful now that we're sorting the autocomplete output by relevance. but then it might help to include extra hints into the output: github.com/oOo0oOo/lean...
if a bluesky fork with its own independent appview adds a feature, does it mean it can be first-class in that fork? not just a "client" feature but server too. you would index your own records in your own forked database, so in principle you can add any features. like "communities" or whatever
my first ai open source contribution ¯\_(ツ)_/¯ appropriately, i ran out of credits before i could test it
