China to Amazon — True Landed Cost
Your supplier said $6. It'll actually cost you $9.73.
What it does
Free tool that calculates true landed cost from Chinese factory to Amazon FBA. Unlike calculators that give you a "shipping cost" box and call it done, this models the real pipeline: MFN + Section 301 + IEEPA tariffs stacked on CIF, real-time freight rates, FBA dimensional pricing, ISF/customs/port fees, and the 2-3% currency spread your bank hides. No signup. Just put in your numbers. Built by a freight broker, not a SaaS company.

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-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.
