Claude used my pipeline to find a counterexample to the Jacobian conjecture

Hacker News - Fri, 07/24/2026 - 8:05pm

About a month ago, I released under CC0 an implementation of a pipeline I had spent two years developing. It’s the pipeline Claude used to find the counterexample to the Jacobian conjecture. The repository history, public release, discussion with one of the original paper’s authors, and two years of development logs document the pipeline’s origin and development.

Proof - https://github.com/JGPTech/Fun/tree/main/Jacobian

The history:

I first released it under CC0 a little over a month ago. You can find the link here: https://github.com/JGPTech/Fun/commits/main/current_paper_locality_boundary_package

This is the paper I was modeling with this pipeline: https://www.nature.com/articles/s41467-026-73900-9

This is where I shared it publicly one of the paper’s authors, which you can see he approved of: https://www.linkedin.com/feed/update/urn:li:activity:7470810642321571840?commentUrn=urn%3Ali%3Acomment%3A%28activity%3A7470810642321571840%2C7471734053742895105%29&dashCommentUrn=urn%3Ali%3Afsd_comment%3A%287471734053742895105%2Curn%3Ali%3Aactivity%3A7470810642321571840%29

How cool is it that Claude used it on a problem this big, and that the mathematical community around this counterexample is now thinking through structures I spent years developing? What a ride.

Ask HN: How would I restore this 101 year old postcard?

Hacker News - Fri, 07/24/2026 - 7:48pm

How do I approach making this legible? Is there a “magical AI” solution these days? I know the basics of image processing and filtering but I can barely read my own handwriting so I suspect I’d need help from AI or someone even if I managed to isolate the signal.

P.S. I hope I’m not doxxing my great great grandfather or anything.

Stripe closed my account with a 0.18% dispute rate

Hacker News - Fri, 07/24/2026 - 7:45pm

I run a UK ltd, ecommerce, personalised products. Started in March, scaled to ~£150K/m in 2 months.

But then... "After conducting a routine review of your Stripe account... we've found that it presents a high level of risk for disputes." Payments switched off immediately. Payouts held for 120 days, balance released in November.

My dispute rate is 0.18% across about 3,900 payments. Their own threshold is 0.75%. We're on 4.7 stars on Trustpilot from 130+ reviews.

After a few hours before the shutdown email, a Stripe salesperson emailed me a repricing form because our volume was growing and they wanted to discuss custom rates.

I appealed tonight and sent fulfilment records matching every order to a tracked delivery, plus bank statements. The dashboard said the review would take until 27 July. It got denied about 90 minutes later. Account is now closed permanently.

Has anyone dealt with this?
