Ventilate · At the right time
Beat the heatwave: when to open, close, and use a fan
What it does
Ventilate helps you stay cool during heatwaves with calm, practical guidance. Set up your windows once, add your indoor temperature (a thermometer helps but is not required), and get clear advice on when to close windows to keep heat out, when to open for fresh air, and where to place a fan so cool air reaches you. Uses local weather and your window directions for per-window recommendations, plus gentle reminders and a heat toolkit.
Know when to open or close each window and where to place a fan using indoor temperature, local weather, sun exposure and home layout.
Ventilate uses your home layout, window directions, indoor temperature, and local weather to tell you when to open, when to close, and how to place a fan , without air conditioning. Know exactly what to do with each window, and when: close, crack open, open wide, or place a fan. Recommendations adapt to your building, layout, window directions, indoor temperature, and the fans you own. See what changes next and when to act. Local forecasts and timely reminders help you catch the useful cooling window. Know when a tropical night, rain, high UV, or pollen changes the recommendation before your next action. Two homes on the same street can need different advice. Ventilate combines your indoor…from getventilate.app

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

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.
