Justbidder
A free directory where products compete for visibility
What it does
Justbidder is a product directory where anyone can list their website or app for free. No paid plans, no approval process, and no upfront fees. If you want more visibility, you can bid to move higher on the leaderboard.
Justbidder is a product discovery platform where businesses can list products for free, reach new audiences, and bid for higher rankings.
Listing is free. To reach #1, you’ll need to exceed the current top bid. Any submission places you on the board at the corresponding rank. Every dollar you pay now ranks you here for 24 hours, and on the all-time board. Everything you need to know about bidding, rankings, and getting the most value from the board. Right after midnight UTC. The Today leaderboard resets every night at midnight UTC, so bids placed late in the day only hold the spot for a few hours before resetting. Placing bids early in the UTC day maximises visibility duration at the top. Your Today ranking resets nightly, but every dollar spent permanently contributes to your All-time rank, which never resets. This ensures…from justbidder.com

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-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.
