Show HN: Bike route planner that follows almost only official bike trails https://bit.ly/4eW8bah

Show HN: Bike route planner that follows almost only official bike trails Hey guys, I built a route planner that is mostly focused on bike touring and using existing bike infrastructure. For each request you're shown what bike tracks/trails your route uses and can further explore them by showing them on map or going to the official trail route. The main idea for the app is to have a friendly and easy to use planner that would make heavy use of official bike trails data (mainly from OpenStreetMap) and make it easy to plan a longer trip using the best possible bike routes out there. Currently the app only works for the Euro region but I'm planning to add North America very soon and then rest of the world. Technical overview: Route finding - Graphhopper sitting in a docker container on a Hetzner server somewhere in Germany. It has 38 GB of graph data(Europe) loaded into RAM for a fast graph traversal. Web App - Next.js 14 with Typescript, backend on the newest version of .NET Map tiles - right now I'm using MapTiler their free tier but planning to switch to my own home server soon and host the maps on it. https://bit.ly/3CEVuDd November 20, 2024 at 09:23PM

Show HN: Browser-based website builder powered by LLMs https://bit.ly/3CxhtvQ

Show HN: Browser-based website builder powered by LLMs I wanted to share what I've been working on - it's a AI site builder that runs in the browser powered by WebGPU and OnnxRuntime-Web. I have got the following all working to varying degrees: - text to code generation - image to code generation - microphone to text to code generation If you are on Mac for instance, it will interface directly with your GPU to power the LLM interface. It only requires downloading the models, and then everything after that is offline. It's not even close to as powerful as Claude or ChatGPT, but I like the idea of having the LLM run directly on your machine. I just did this for fun, but I am looking for a new role if anyone's hiring - https://bit.ly/3CxhuzU ! More technical insight: - I also got the Typescript / React app to compile itself in the browser via a service worker https://bit.ly/3Z0M1gS but took it offline due to some oddities with service workers. - A lot of the new speech models are a lot better than anything built into your phone / computer. I wonder when more computers will have them built in. - I added a CSP to the iframe only because I was worried about spamming sites since I update the iframe anytime a new token comes in. So if you have an image on the page it will get reloaded every time the iframe is updated. Otherwise there would be no reason for it. https://bit.ly/48VHWiJ November 19, 2024 at 09:24PM

Show HN: Nova JavaScript Engine https://bit.ly/4fNTlDm

Show HN: Nova JavaScript Engine We're building a different kind of JavaScript engine, based on data-oriented design and willingness to try something quite out of left field. This is most concretely visible in our major architectural choices: 1. All data allocated on the JavaScript heap is placed into a type-specific vector. Numbers go into the numbers vector, strings into the strings vector, and so on. 2. All heap references are type-discriminated indexes: A heap number is identified by its discriminant value and the index to which it points to in the numbers vector. 3. Objects are also split up into object kind -specific vectors. Ordinary objects go into one vector, Arrays go into another, DataViews into yet another, and so on. 4. Unordinary objects' heap data does not contain ordinary object data but instead they contain an optional index to the ordinary objects vector. 5. Objects are aggressively split into parts to avoid common use-cases having to reading parts that are known to be unused. If this sounds interesting, I've written a few blog posts on the internals of Nova over in our blog, you can jump into that here: https://bit.ly/40YfudQ https://bit.ly/40RuAlr November 18, 2024 at 12:07AM

Show HN: Knight's Graph – game based on the Knight's tour problem https://bit.ly/40PXmCY

Show HN: Knight's Graph – game based on the Knight's tour problem When I was in high school, my dad showed me how to play Knight Tour on a piece of paper. Many years passed before I decided to create the Knight's Graph app. “Knight's Graph” is an intellectual puzzle game based on the classic knight tour problem, known since the 18th century. Your task is to move the chess knight across the board so that each square is visited exactly once. Test your logical and strategic skills in an exciting game where every game is a new challenge! The app is already available for download on the App Store. Google Play will be available a little later. App Store: https://apple.co/3Z8sqwB...

Show HN: Next Beats – A Modern, Customizable, Open Source Lofi Music Player Hey everyone, I've always wanted to build my own lofi player, and I recently added it to one of my projects, You-TLDR. I decided to open-source it so more people can play around with it and make it their own. NextBeats is a modern, customizable lofi music player built with Next.js and TypeScript. It features a retro TV-style interface, YouTube integration for endless lofi streams, sound effect mixing (rain, cafe, etc.), and theme customization. Perfect for coding, studying, or relaxing, it lets you add custom channels, control music and effect volumes independently, and save settings locally. Open-source and mobile-friendly. Appreciate any feedback! https://bit.ly/3YZZvd0 November 17, 2024 at 06:31AM
