Let sponsors bid on your ad slots
What it does
Most creators price sponsorships by guessing, then lose a week to DMs. slotsbid runs your slot like a lot at auction: publish it, sponsors bid against each other openly or by sealed offer and the top bid wins. You approve every ad before money moves, and payment settles on the platform. No rate card, no haggling, no chasing invoices. Free to set up, no subscription we take 10% only when a slot sells. Your flat rate was probably too low.

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.

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.
