Loc2country – Location coordinates to country in microseconds

In plain words

Loc2country is a tool that converts geographic coordinates into country names with microsecond response times. It is designed for developers who need fast country identification from latitude and longitude data. The tool is built for quick integration and efficiency, making it suitable for applications requiring real-time location-based country lookups. It is available as open-source code on GitHub.

  I often need to convert times between time zones, so I built this tool to convert between them quickly and efficiently. 1. Add the cities you want to convert between (this is saved in the browser). 2. Drag on the map until the time on the source city is the time you want. 3. Look at the time at the other city. It's even more helpful to use on a phone since it doesn't require typing to convert between time zones or look up the time in another city (assuming you already added the cities you care about). If you need to convert a time far in the future, you can input the date and time in the…

  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,…

  I made a little tool to practice country positions on the world map2023 · learn-worldmap.netlify.app · ▲45

  Hi HN, I built a little tool to help me get better at remembering country locations on the map: https://learn-worldmap.netlify.app/ It's made from plain HTML/CSS/JS, and not intended to make any money or anything. Just thought that maybe someone else may enjoy it. Also of course happy about any feedback! Cheerz.

  I figured this might be useful to folks. It's a simple PHP server that requires a single-table database (It's fairly "agnostic," but all my uses are in MySQL). I won't publish any of the servers that I've set up for my apps, because someone is bound to write an application that drives my bandwidth into the stratosphere. I could definitely take it further, but this gives me all I need for my purposes. Here's an app I wrote, that uses it: https://apps.apple.com/us/app/we-are-never-alone/id650482602...

  Hi 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…
