A puzzle I couldn't solve for a year – cubers cracked it in an hour
Dev here. I created a puzzle that looks like Rubik's cube but works differently. Instead of turning faces, closed bands of 12 stickers slide around the cube. Every scramble is solvable. I built on-device AI solvers that solve it in about 60 moves (sometimes substantially less than that) I'm not even a cuber so since I created it I've been thinking that no human can solve it. Until this Tuesday when I showed it to r/Cubers. It took them about an hour to find a solution. The first human solve was about 240 moves using mostly (how they call it) 4-move commutators:…

In plain words
SkimmIQ is a puzzle that resembles a Rubik's cube but uses a different mechanic: instead of rotating faces, closed bands of 12 stickers slide around the cube. The developer created on-device AI solvers that can complete any scramble in approximately 60 moves. Playable directly in a browser with adjustable difficulty levels, the puzzle is designed for anyone interested in exploring a new type of 3D puzzle mechanics. The first human solver completed it in about 240 moves using mathematical sequences called commutators.

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…
