What it does
A pure-deduction code-breaking game. The global Daily Challenge is provably fair: each day's code comes from drand, a public randomness beacon nobody controls — not even the dev. 7 modes, no-account challenge links, playable on web too.
A four-digit code, feedback after every guess, and no luck anywhere. Play a round here, then get CipherBreaker free on iPhone.
Every code can be cracked by logic alone: read the feedback, eliminate the impossible, close in. The display runs the app's own evaluator, so the round below is the real thing. 10,000 codes are possible. Deduction is how you cut them down. Two of the classic modes report the same truth in different languages. One paints it. One counts it. Green sits in the right slot. Gold is the right digit in the wrong slot. Grey is not in the code. No colours. Two numbers: how many digits are exactly right, and how many are right but misplaced. Digits never repeat, so 5,040 codes are in play. Two digits nailed. One digit present, wrong slot. One not in the code at all. Each mode changes what the code…from cipherbreaker.app

Clipto MCP▲655Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
