Put Greenland on the Moon (interactive map for size compare)
I built a drag-and-drop map playground to compare the true sizes of countries and visualize Mercator distortion, just for fun and sharing. Open source + easy to replace the GeoJSON with your own data. Demo: https://www.runcell.dev/tool/true-size-map Source: https://github.com/ObservedObserver/world-map-reality

In the maker’s words, at launch
Just built a small tool and created some comparsion of country size vs. planets. Greenland seems larger than i thought. The tool allows you to drag a counry to other planet to see the size there.

Hi HN, I made a web game to practice country locations a while ago and HN liked it, so I thought I'd post my updated version as well. As for how the game works and feels, I'd really recommend you checking it out for yourself, it's free, no signup, no ads. The tech stack is Vue + ts + Tailwind/Daisy for the looks. The learning algorithm is a slight modification of the ts version of FSRS. If you have anything to add, it's open source as well (https://github.com/koljapluemer/learn-worldmap), although not well documented yet. In the end it's just a little sideproject,…
TrueSize.net2025 · truesize.net · ▲6Hi! Thanks again for all the great feedback on my earlier post. I’ve added a lot since then and wanted to share an update. I’m also very open to more ideas or criticism. For anyone who hasn’t seen it yet, TrueSize.net is an interactive tool that lets you visualize and compare the real size of countries on a world map and globe (without Mercator distortion). What’s new: - Support for 140k+ regions, provinces, states, and territories - not just countries. - Many regions now include population, area, and short descriptions. - Official mobile apps on iOS and Android (links are on the site,…

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…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
