EcoEnergyCalc's answer:
EcoEnergyCalc offers 20+ specialized energy and carbon calculators in one place โ covering everything from electric bills and solar ROI to carbon footprint and water usage. All tools are free, instant, and require no signup.
EcoEnergyCalc's answer:
Unlike general-purpose calculator sites, EcoEnergyCalc focuses exclusively on energy costs and environmental impact. Every calculator is built on official data sources (EPA, EIA, NREL) and designed for US and European homeowners making real financial and environmental decisions.
EcoEnergyCalc's answer:
Homeowners and renters in the US and Europe who want to reduce energy costs, evaluate solar or EV upgrades, or understand their carbon footprint โ without needing to sign up for anything.
EcoEnergyCalc's answer:
EcoEnergyCalc was built to make energy and environmental data accessible to everyday people. Too much useful information is buried in PDFs or behind paywalls โ we turned it into simple, free calculators anyone can use instantly.
EcoEnergyCalc's answer:
Plain HTML, CSS, and JavaScript. Hosted on GitHub Pages with Cloudflare DNS. No frameworks, no backend โ fast and lightweight by design.
I've started using this as my main IDE for new projects when I'm trying things out. If it keeps getting better at the rate it has been, it'll be even better than coding locally.

Managing reactive state and dependent computations in JavaScript can get complex, especially when combining asynchronous and synchronous data. RS-X is a library that allows you to bind expressions to plain objects and makes the parts of the model used by those expressions fully reactive. Dependent computations automatically update when the underlying data changes. RS-X is framework-agnostic. While it can drive UI... - Source: Hacker News / 6 months ago
I like htmx, LiveView, React and Solid. They are great at different points, so I try to combine them in Solv (Stateless Offline-capable LiveView) and write a prototype to show the benefits. Solv's main idea is that stateless servers keep client's state in a volatile cache. It enables server components that are also interactive, which is best of both worlds between LiveView and htmx. Then fine-grained reactivity is... - Source: Hacker News / 9 months ago
