24 alternatives to NukeCast – If it happened today, where would the fallout go

I built NukeCast because I’ve always wanted a tool that answers one question fast. If it happened today, where would the fallout plumes go and where would you drive to get out of it. NukeCast uses weather forecasts to drive a Lagrangian particle dispersion model with wet and dry deposition. Scenarios are defined by selecting strike site(s) and yield(s); the setup uses preselected US sites and yields based on FEMA emergency data. Outputs are shown as estimated ground level radiation dose at the surface over a 12 hour integration. Free to use with limits, and a paid tier if you want more…

    Hey HN! Just for fun, I built an interactive Hacker News Simulator. You can submit text posts and links, just like the real HN. But on HN Simulator, all of the comments are generated by LLMs + generate instantly. The best way to use it (IMHO) is to submit a text post or a curl-able URL here: https://news.ysimulator.run/submit. You don't need an account to post. When you do that, various prompts will be built from a library of commenter archetypes, moods, and shapes. The AI commenters will actually respond to your text post and/or submitted link. I really wanted it to feel…

    OP here: I created this visualization tool as the byproduct of a supply chain class I taught at Columbia. The pedagogical exercise grew into a full blown visualization and paper about global oil trade. The model: The mechanics are the same as the financial network Eisenberg-Noe: Instead of banks, every country consumes oil interconnected via bilateral trading. Shocks propagate throughout the network, depleting oil reserves when bottleneck nodes (such as the Strait of Hormuz) are blocked. Insights: The interesting part is the mechanics of how the crisis unfolds: for example, France receives 0…

    Simulate anything on a map from a text prompt -- and conduct risk analysis against LiveUA map's global realtime data points from social media and news sources. I trained a GPT-2-size model on historical incident data used to predict things that will go wrong. As historian Benjamin Breen mentions, the leading language models are good historians, so the application will simulate historical events pretty well also. I include a Multi-Agent RL Urban Mobility model in progress displayed on the map as small white cubes representing traffic and pedestrians. Around SF, it uses real census data and…

    It's free to play on steam, but you'll need a computer with a dedicated graphics card. I just released a new version after first releasing it 18 months ago. It's been a hard slog to scrounge time as it's not my day job but that's life. There's a ton of obvious improvements in the future (weather systems, temperature, varying rainfall, ice/snow, more biomes, more plate tectonics, lava, etc) but all suggestions/feedback is welcome.

    This was something I built while trying to look for housing in Toronto that was decently transit-accessible to my office while still cheap. The backend is written in Rust. It parses public GTFS data from transit agencies and performs a simple heuristics-based BFS on the bus lines to calculate how long to reach all points in a city. The frontend uses React and Mapbox GL to render each individual road segment based on how long it takes to reach. This project was a great excuse to learn Rust, deployments, and mapping. The source code is here if you are interested:…

    I sometimes pick up random projects just because I can, this was one of those times. I made it as a week long project a while back this year but never shared here, so thought to go for it haha. I created a game inspired by Doom and the backrooms called The Backdooms under 2.4kb in minified html. (for reference, this entire post would be around 1.8kB haha) I had to use a not popular way of using GZip with Zlib headers (had to write my own script for compressing it, also in the repo) to eventually convert it a size 40 QR code that works right in your browser using Decompressionstream API.

    Hi all, I am not an expert in nuclear energy but I've always wondered and found it difficult to get a clear picture about the amount of nuclear stations located in a specific region. So I built this tool that shows all the nuclear plants in the world, scaled by their capacity and with indication of their status. Clustering is enabled by default and allows to see the sum potential capacity of a region. It's a fun tool for me: e.g. disable clustering, scale circle radius to 70%, go to EU, and you'll see Germany has shutdown all of the stations. Ofc it's a widely known fact, but what came to my…

    I built this because I wanted a fun way to practice incident debugging without the stress of an actual outage. You get a production incident scenario, read through logs and metrics, and figure out what went wrong. 9 scenarios so far across beginner to advanced. Built with Next.js. Free to play, no signup required to try it. Would love feedback on the scenarios - especially if you've dealt with real incidents that would make good puzzles.

    Hey HN, the is Chris, creator of FireDBG. We’ve been working on this debugger just about a year now. Time travel debugging isn’t a new concept, the new idea here is to use call tree visualisation to help us navigate the debug trace. It supports various Linux distros on x64 and macOS on x64 and M1. It’s only available for Rust right now, but we do want to bring this debugging experience to other programming languages. Please give it a try! Would love to know your thoughts. What’s your anecdote in debugging programs? My stupidity is usually in the form of: after a few hours of debugging, I…

    I've posted this game here before, hopefully a repost is fine as the game has changed quite a bit (improved AI, improved mapeditor, much quicker gameplay, etc). Game is based on JavaScript/Canvas and WebSockets. On the browser side the map is pre-rendered (as a background image), just the mobile units/buildings and animations are dynamically rendered. The lobby server is made in node.js, but the game server is C++ for performance reasons (mainly the pathfinding). I found the C++ WebSocket libraries out there to be too difficult to use so I made my own based on the rfc. Overall I…

    Hi all This has been my hobby project for quite a few years now It started as a small engine to serve as a sandbox to try out new 3d graphics ideas After adding many features through out the years and re-writing the entire engine a few times, this is the latest state It currently supports loading models with animations, textures, lights, shadow maps, normal maps, and some other goodies I've also recently added voxel raymarching as an alternative renderer, along with a fun physics simulation :)

    I’ve been experimenting with Rust lately and wanted a project that would help me explore some of its lower-level and performance-oriented features. Inspired by Sebastian Lague’s videos, I decided to implement my own ray tracer from scratch. The initial goal was just to render a simple 3D scene in the browser at a reasonable frame rate. It evolved into a small renderer that can: • Run locally or on the web using wgpu and WebAssembly • Perform mesh rendering with a Bounding Volume Hierarchy (BVH) for acceleration • Simulate both direct and indirect illumination for photorealistic results • Be…

    Hey HN, this is Will and David from Fortress (https://news.ycombinator.com/item?id=41426998). We use a lot of async Rust internally, and created this library out of a need for an async-aware concurrent hashmap since there weren’t many available in the Rust ecosystem. Whirlwind is a sharded HashMap with a fully asynchronous API. Just as dashmap is a replacement for std::sync::RwLock, whirlwind aims to be a replacement for tokio::sync::RwLock. It has a similar design and performance characteristics to dashmap, but seems to perform better in read-heavy workloads with tokio's…

    This is a service I've built to provide equirectangular cloud maps of the whole Earth, updated every 3 hours, for free. It's based on infrared and visible light data from EUMETSAT, processed to enhance the clouds and try to reduce the impact of surface temperatures on the final image. I built it because it's surprisingly hard to find these kinds of images in a format that's useful to developers and hobbyists. I was building a 3D ISS tracker and wanted to include live clouds but couldn't find anything good, so I got sidetracked, and here we are.

    So, after years of abandoning Rust after the hello world stage, I finally decided to do something substantial. It started with simple line rendering, but I liked how it was progressing so I figured I could make a reasonably complete PSX style renderer and a game with it. My only dependency is SDL2; I treat it as my "platform", so it handles windowing, input and audio. This means my Cargo.toml is as simple as: [dependencies.sdl2] version = "0.35" default-features = false features = ["mixer"] this pulls around 6-7 other dependencies. I am doing actual true color 3D rendering (with Z buffer,…
