Neural-hash-collider – Find target hash collisions for NeuralHash launched on August 19, 2021 with 623 votes, #8 of 2,953 launches that month and more than 99% of that year's launches. The site was still online in September 2026, 5 years on.
In plain words
Neural-hash-collider is a tool that finds target hash collisions for NeuralHash, Apple's perceptual hashing system. Designed for researchers and security analysts, it demonstrates vulnerabilities in neural hash algorithms by generating images that produce the same hash values. The tool is available on GitHub and addresses concerns about the robustness of perceptual hashing systems used in content identification.

Hey all My name is Sindre, and I am the CTO of Scrimba (YC S20). For the last 7 years, I have written all my web apps in a full-stack programming language called Imba. It compiles to JavaScript and its main goal is to make web developers more productive. I just launched a major overhaul of Imba, so I wanted to share it here on HN, in case anyone are interested in learning more about it. It is very opinionated, so some of you might not like it, but I would love to hear anyones feedback regardless. Constructive criticism appreciated! The backstory: Imba initially started in 2012 as an effort…

Hello HN, Over the last year we've been building ente[1], a privacy-friendly, easy-to-use alternative to Google Photos. We've so far built Android[2][3], iOS[4], web[5] apps that encrypt your files and back them up in the background. You can access these across your devices, and share them with other ente users, end-to-end encrypted. You can also use our electron app[6] to maintain a local copy of your backed up files. We've built a fault-tolerant data replication layer that replicates your data to two different storage providers in the EU. We will be providing additional replicas as an…
