What it does

YouSaidThat lets you seal any prediction. A market call, a hot take, a thesis — with SHA-256 hashing, AES-256-GCM encryption, and RFC 3161 timestamps. No one can see it until you reveal it. Once you do, anyone can verify you wrote it exactly then, without trusting you or any platform. Built on open cryptographic standards. No accounts needed. Fully auditable. Your proof lives outside any server.

Record your ideas about the future. Seal them in time. Reveal them when the year arrives.

    I built AI Trust Proof — an experiment in recording human good faith on-chain so it can be independently verified by people, software, or (eventually) AI systems. What it does (today) - Lets you sign a plain-English pledge and record its signature hash + metadata on Solana (devnet). - Mints a symbolic NFT badge pointing to that record. - Creates a verification page that shows the pledge, signature, and on-chain proof. What it’s not - No token, no airdrops, no yield. - Not a reputation score or KYC. - Currently just one signal: "Pledge signed." Why - If AI systems begin prioritizing who to…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  • Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  • Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
