  A journaling service that runs over WhatsApp2024 · todayhasbeen.com · ▲126

  Hey Hacker News, I’m excited to share a tiny service that’s very close to my heart - Today Has Been. Here’s how it works: We have a phone number that has WhatsApp Business API enabled. Your messages sent to this number (after you activate your free trial) are added to your journal. It’s a super light weight journaling service - no app download or registration is required. We also send you a daily nudge asking “How did your day go?” and after you have a few posts we send you a random blast from the past. Why I built it: I was an active user and fan of Ohlife - only journalling app that could…

  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…
