merca.earth

What it does

merca.earth is an on-chain map of Earth where anyone can own any place. Draw any polygon anywhere. Register it. Then make it yours: name it, upload an image. Your parcel becomes a visible place on the map that anyone can see. The catch: every parcel is always for sale. Anyone can buy yours at the current price. Prices escalate with every trade. Six hierarchy levels. Own a region, earn a share from every sale inside it. The map fills up with what people think is worth claiming.

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,…

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
