Products that do what CoordConversions NPM Module for Map Coordinate Conversions does
I have been working on a project that has multiple repos, all of which have to convert between multiple map coordinate types, so I made an NPM module that allows you to parse and convert between Decimal Degrees, Degrees-Minutes, and Degrees-Minutes-Seconds coordinate types. Niche? Yes. Useful? Also yes (I hope)!

I've recently been working with real-time geoJSON data at a rate of 50+ queries per second. SaaS solutions can be prohibitively expensive at this rate, thus, I created go-reverse-geo. Data is pulled from geonames.org and is stored in MongoDB (a requirement of my current project). It is very much a work-in-progress (I wrote it this morning). Hope someone finds it useful. https://paranoia.dev/vivi/go-reverse-geo

Requirement: - Excellent feedback during development - Debugging with source maps Method: I'm using these scripts in package.json. "scripts": { "di": "node-inspector -d=7000 -p=8000 --save-live-edit --hidden node_modules/", "ds1": "babel ./server -d ./build/server -s -w", "ds2": "nodemon --watch ./build/server --delay 100ms --debug=7000 ./build/server/main.js" }, Then run "npm run ds1; npm run ds2; npm run di" Why: I took some time to put this together, after navigating all the tools out there. I personally find this to be "correct". Thought I'd…

Hi, this is my first npm package that is getting a couple of hundreds downloads. It's a super simple CLI time tracker, mostly suitable for 9 to 5 jobs I hope you check it out and tell me what you think. Demo and etc. https://github.com/omidfi/moro

Oclock is an interactive 3D WebGL globe that visualizes real-time daylight cycles. Built with Globe.gl and pre-processed spatial data pipeline. Processing Pipeline The data generation is handled by timezone_data_generator.py. This script performs the following: 1. Geometry Analysis: Uses shapely to find a representative point inside each country's boundary. 2. Timezone Mapping: Uses timezonefinder to look up the specific IANA timezone string for those coordinates. 3. Data Injection: Injects the timezone and coordinates back into the GeoJSON properties for use by the frontend. Live Demo:…

We've rolled out a feature for openbase.com that we think is a DX game changer for Node devs. Since the emergence of ECMA Script modules, it's been a continuous guessing game as to what kind of exports a package has. That's never really been discoverable without using a site like unpkg, or installing the package and inspecting package.json. Openbase now displays the ES Module support level (e.g. type of exports) on all of their package pages. We added this feature because our devs are some of the folks continually caught off guard by installing an NPM dependency only to find out it's…

Hey HN. I made a micro site one recent evening to see upcoming (and recent past) timezone transitions. At my job, we have some timezone specific code where we often see spikes in metrics due to random timezone shifts around the world. Just for fun, I wanted a way to easily see where and what this timezone shift might have been, so built this mini site to do so. Its fully clientside and works by making use of the Internationalization API, so if you need an API for this you're coming to the wrong place, but feel free to yoink the code. Its just one fat index.html file. Served off my VPS via…

I’ve been working on MicroState, a city builder prototype written entirely in vanilla JavaScript using the HTML5 2D Canvas API. My goal was to see how far I could get with a 2.5D isometric style simulation with vanilla JavaScript built very simply and drawn entirely with procedural generation for maps, tiles, roads, trees, buildings, etc. The most interesting element is probably the terrain model, which allows for fairly arbitrary terrain. Although some of the generated graphics like trees are cached as sprites, buildings- which are much more intensive to draw - are not cached yet, and many…

VibeSolve is an open-source tool that turns a plain-English description of an optimisation problem into Timefold code. Mathematical optimisation is a branch of mathematics and computer science that searches for the minimum/maximum of objective functions, and has applications in transport, logistics, scheduling etc. We are exploring where LLMs can add value in optimisation algorithm development, and where they get in the way. Right now, it works well for rapid prototyping. It does not create production-ready code and requires technical skills to use. It is noticeably better at creating…

Hi HN! RΞASON is an OSS Typescript framework for developing LLM apps that uses Typescript's interfaces to get structured output from an LLM. While there are other TS LLM frameworks, I think RΞASON fills a unique space in the market: it's laser-focused on only three areas and, most importantly, actively stays away from pre-made prompting & retrieval. I've been in the LLM space since GPT-3 originally came out, and I've always had problems with other frameworks, such as LangChain. I dislike that they focus a ton on out-of-the-box prompting & pre-made agents — I, as the dev, should be the one in…

Hi HN, we’re Dylan and Matthew, building sublingual (https://github.com/sublingual-ai/sublingual), an open-source LLM observability tool you can use with zero code changes. As developers focused on iterating and building features as fast as possible, we felt observability would’ve been a helpful tool to have, but we found existing solutions had too much overhead to set up. So we gave ourselves the challenge of building an observability tool that you can integrate without changing a single line of code in your project. How it works Run your python application as usual with…

hi! I’m a 17 y/o dev and I made this so I could show my wpm in code rather than just normal text :) this was my first project that I made awhile back but wanted to share it today. I used React and got the LeetCode samples by webscraping a site that had all the solutions. you can read more about the site in the "about" page. here's the repo: https://github.com/max-lee-dev/hackertype https://twitter.com/maxleedev

I've spent the past few months building a language that is 99% compatible with CoffeeScript and 99% compatible with TypeScript. Essentially a reimagined CoffeeScript for 2022 that finished ES6s partially completed features, adds TypeScript support, and keeps the niceties of CoffeeScript. Example features: - Const assignment shorthand user := getUser() --- const user = getUser() - Parens optional and braceless nesting if x > 0 return --- if (x > 0) { return } - &fn shorthand nums.map &+1 --- nums.map($=>$+1) And a heck-ton more: https://github.com/DanielXMoore/Civet A big…
