RepointQR
Change your QR link after printing — no reprint needed
What it does
Create print-safe QR codes you can repoint anytime. RepointQR lets you change a QR code’s destination after it has been printed, so menus, posters, packaging, business cards, and PDFs never need a reprint. Create static or dynamic QR codes, track scans, customize designs, and add password protection or expiration when needed.
Create editable QR codes you can update after printing. Generate URL, PDF, WiFi, email, phone, text, WhatsApp, and location QR codes.
Paste your link, choose a QR type, preview it, then customize and download. Only you can see this name. Use it to find the QR code in your dashboard. Editable QR keeps the same printed code and lets you update content later. Only you can see this name. Use it to find the QR code in your dashboard.

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.
