Show HN: CityEdit – Open-source map for voting on NYC street changes

1 hour 12 min ago

CityEdit (cityedit.org, https://github.com/edbltn/city-edit) is a map where anyone can propose street changes, e.g. safer crossings, new bike lanes, improved tree beds. Neighbors can then vote on those proposals.

We just soft launched the app by hanging posters with QR codes at NYC's statistically most dangerous intersections (from open crash data at https://data.cityofnewyork.us/Public-Safety/Motor-Vehicle-Co...). Read more at https://sphericalharmonics.substack.com/p/city-edit-first-ed...

(A poster turns out to be a great distribution channel - it reaches exactly the people who use that street, when they are using it!)

The ultimate lofty vision is to build a sensorimotor loop that can awaken a city's collective consciousness: the community perceives its desires, proposes, votes, acts.

Two disclaimers: 1. A vote on a map is more of a signal than a mandate, and may be unlikely to inspire government action. Instead, for now, we are going to enact what changes we can through some cheeky tactical urbanism. (https://luma.com/3mvlme31)

2. There is selection and presentation bias inherent to how we've built this. Our aim is to be as transparent as possible about who is participating, and who is missing, rather than faking general consensus. We're also seeding maps with existing commute data to fill in gaps wherever we can (e.g. Citibike trip data on the NYC Bikes map)

Critiques are welcome, especially skeptical takes on whether this type of civic feedback loop can work. But please be constructive too!

Show HN: Humor Arena – Which frontier model is funniest?

1 hour 22 min ago

What if you could measure humor?

Well we've trained a model on our own dataset of ~50k human ratings to detect what jokes people find funniest. We know it's part objective, part subjective component. Subjective is out of our depth for now haha

The main results: Fable 5 is funniest - beating the average model 67% of the time, with GPT 4o last at 17%.

Other findings: - The models never refused to try, even with dark prompts - Thinking longer has a slight benefit - Absurdness correlates negatively with joke quality

Some methodology notes: - We benchmarked our model against the human majority and it agreed 72% of the time in a blind sample test. - We had 51 US adults rate the jokes, each blind to the models, with joke order randomized, and quality checked for attention and speed. - To rate some yourself visit https://pair.laugh.so

The full benchmark here:

Am taking requests if there's more research you want to see! Cheers
