CertMinder
Never miss a landlord compliance certificate again
What it does
CertMinder tracks every compliance certificate across your rental portfolio: gas safety, EICR, EPC, PAT, HMO licences, fire safety, all in one dashboard. Automated reminders fire before anything expires, so nothing slips through. One click generates an audit-ready compliance pack for councils or lenders. Built by a landlord tired of chasing expiry dates across spreadsheets and email. Free plan available, paid from £25/month.
Compliance tracking for UK letting agents and landlords: gas, EICR, EPC, PAT and HMO across your portfolio, with reminders before anything expires.
CertMinder UK tracks every property, certificate and expiry — then gets the job done. Your contractor and your tenant book the visit between themselves, and you see the confirmed appointment without chasing either of them. Free · 60 seconds · no signup. Also built for private landlords with 1–25 properties. Expiry dates live across emails, notes, calendars and half a dozen spreadsheets. Nobody has the full picture. Renewals rely on someone remembering. When the office is stretched, or someone leaves, things slip. A lapsed gas certificate becomes a complaint, then a dispute, then a problem with your landlord client. Enforcement is rising and fines are increasing. One lapse can cost far more…from certminder.co.uk

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.
