What it does
A minimalist calculator for square roots, in French (“racine carrée”). Handles positive, negative, and decimal numbers. Designed to be mobile-friendly, ad-free, and super fast.
Calculate any square root with the Racine Carree Calculator—positive, negative, or decimal. Fast, accurate, mobile-friendly, and 100% free to use.
If you enter 49 into the Racine Carree Calculator , it will return 7 —because the square root of 49 is 7 (√49 = 7). Try entering different numbers above to instantly find their square roots. If you enter -81 into the Racine Carree Calculator , it will return 9i —because the square root of a negative number involves an imaginary unit (i). Mathematically, √(-81) = √(81) × √(-1) = 9i. This helps you understand how the calculator handles complex numbers as well. Try it yourself, or check the example image below for reference: Calculating square roots can be tricky—especially when dealing with negative numbers or long decimals. This tool takes its name from the French term for square root…from racinecarreecalc.com

Figr.app – a multi-user, notepad style calculator (desktop app)2022 · figr.app · ▲275Hi all, just posting an update to my previous Show HN, where I announced a side-project I worked on which was a (web version) of a multi-user, notepad style calculator: https://news.ycombinator.com/item?id=31817997 After a couple of user requests (and having a good think about it) I decided to migrate the web UI to create a Mac and Windows desktop app. After using it a little bit, I feel this is a much better experience than the webapp, and reduces a lot of the friction if I wanted to run a few small calculations. You can find the download links below:…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Trickle - Magic Canvas ▲1,064Hey HN! Introducing Trickle Magic Canvas: the world’s first Agentic Canvas, where you can visually co-create apps and websites with AI, from idea to production. Why is a canvas better? Most AI tools today rely on linear chats or text prompts. We believe that limits creativity and clarity. Canvas changes the game. 1. Every version & page at a glance. Each page and sub-page lives on a timeline. You can quickly browse, edit, and preview progress like a living, visual document — no more digging through chat logs or scattered states. 2. The canvas is the context. Unlike linear chats, you can…

Today marks ten years, 3653 consecutive days, of running at least one mile every day under the USRSA rules [1]. To celebrate, I built an interactive dashboard that turns a decade of GPX files into charts you can explore. Running has truly changed my life: I've made lifelong friends, explored beautiful places, and more importantly invested into my own health and fitness, which I'm starting to see the positive benefits as I get older. The stack is pretty simple: a NextJS app, with a Postgres database to keep all my running data, and all the stats are pre-computed and cached in Redis, so I…

Made this website as an exercise in vibe-coding and GCP. It was posted about a few times around the internet, on sites like Morning Brew (https://www.morningbrew.com/issues/business-buzzkill), MetaFilter (https://www.metafilter.com/209703/Draw-A-Fish), boingboing.net, etc. I think it's cute! I built a basic CNN trained against penises and swastikas, and then anything that doesn't hit the 63% confidence score gets sent to a mod queue, a vibe-coded fish-tinder…

Hi HN - I made a site that takes a UK postcode, grabs the local MP's information and generates an AI mockup of what their ID might look like. It's a small, silly protest at the stupidity of the Online Safety Act that just came into force. edit - My open AI credits got hugged to death, please use a known postcode (like one from Kier Starmer's constituency, WC2B6NH) in the meantime.
