CSV Signal

What it does

CSV Signal is a local Python tool for solo founders and operators who export orders to CSV. It compares the latest week with the previous one, calculates net revenue, orders, AOV, refund rate, and top products, then flags revenue drops, refund spikes, and product concentration. It generates Markdown and HTML reports with no dashboard, API key, account, or data upload.

Your store, payment processor, and spreadsheet already have the numbers. The hard part is turning them into a clear answer.CSV Signal is a local Python command-line tool that turns a normalized order CSV into a practical weekly operations report. It compares this week against last week and flags the changes that deserve attention.No accounts. No dashboard. No data upload. Your CSV stays on your ma

  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…

  I trained a 125M model to autocomplete piano on-device▲598

  I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
