What we found

01
Alloy
alloytools.org

A software-modeling language and analyzer used to check an authorization design with Codex.

Source discussion: LLMs are making formal software verification feasible at a much larger scale

“Along these lines, we used Codex to collaboratively build an alloy model for verifying the authorization model of GoodMem. After building the model, we implemented the code based on it, and, while there could be a gap in the translation process, several hours of red-teaming the server (w/attacker source code access) to try and produce a privilege escalation attack using GLM 5.3 failed.”

uuid-utils
pypi.org

A Rust-backed Python UUID library recommended after a draft-format UUIDv7 compatibility trap.

Source discussion: UUIDv7 doesn't have the properties you think it does

“One of my favorite things about UUIDv7: the package https://pypi.org/project/uuid7/ does not implement compliant UUIDv7s, it's from a wholly incompatible draft format. That was not a fun debugging session. https://pypi.org/project/uuid-utils/ is what you want :)”

Color Names
github.com

A handpicked color-name dataset that makes palettes and debugging output easier to read.

Source discussion: Color Names

“Oh, it's yours! Thank you. I've been using this dataset for two years now. It's really helped me in game development; specifically being able to use words instead of hex values in things like error messages and modeling palettes.”

06

An MCP server for exploring research directions with coding agents; strongest around AI topics.

Source discussion: The alien space of science: Coherent but cognitively unavailable directions

“We haven't done concrete measurements yet, but my intuition is that the quality of Lacuna proposals is a function of density of topics / research directions. Lacuna is most dense around AI topics; for neighboring ones (e.g. bio, physics), I'd join you in tempering expectations. The one thing I could recommend however is rigging up the mcp (https://github.com/tiptreesystems/lacuna-research-mcp) to your code agent and trawling the database for ideas worth thinking about.”

Local Wikipedia
edjefferson.com

A nearby-Wikipedia explorer that helped a traveler discover neighborhood history and museums.

Source discussion: Local Wikipedia: Wikipedia, but only for things a half hour walk from you

“I used this during my walk around around Tirana, Albania this morning where I'm traveling right now. I learned some interesting history about the neighborhood I'm staying in. Also discovered some museums and buildings nearby that I'd like to check out now. When I visit a new city I usually spend time poking around Google Maps to discover points of interest nearby, but this will be another useful resource. Thanks!”

OnKey
singonkey.app

A free Mac singing trainer that compares your pitch against songs you choose.

Source discussion: Show HN: OnKey – I'm a bad singer, so I built an app to show where I'm off-key

“i love the feature where you can select a song to compare to.”

“Singing is about so much more than just hitting the right notes. Breath management is one of the most important skills you can develop to improve your singing. Proper vocal technique helps you avoid injuring your voice when tackling difficult songs. Learning to recognize and use techniques like belting, twang, head voice, chest voice, vocal fry, etc., can really bring your singing to life. Prosody and rhythm training help you develop good timing (one of the most important aspects of music), and there's so much more to it. This kind of app is great for getting started and getting a taste of what singing involves, but it would be awesome to cover these other aspects as well, or at least mention their existence for aspiring singers.”
