  I'm challenging your clicking speed with this game I rebuilt2022 · projects.marcnitzsche.de · ▲25

  Hello HN, last week, I stumbled over an old project of mine called Click The Number. I built it about six years ago to compare my clicking and reaction speed with that of my friends. The idea is simple – just click on the numbers in orders as fast as possible. I couldn't resist and rebuilt a lot of parts again, making them a bit nicer. I updated the design and added some features like a personal high score. It lets you keep track of your own best time (which makes it ever so _slightly_ more addictive). I'm curious what you think about it, and if you have any ideas where I could take it. Have…

  Don't click this button – testing the internet's patience2025 · onebutton.click · ▲12

  This weekend I was looking for a side project to play around with Go so I built a simple web experiment to test the self control of the internet: it has a single button, a live click counter, and a timer. I want to see how long the internet can collectively resist clicking it. The backend is a very simple Go binary with Go's std http server, web sockets, a WAL-style log of clicks, plain CSS and Comic Sans. Inspired by Silicon Valley's (HBO series) Bro app, OneMillionCheckBoxes and Cookie Clicker

  Clipto MCP▲655

  Hey 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…

  Simple algorithm and color space to generate diverse skin tones▲627

  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…
