New top story on Hacker News: Show HN: Beatsync – perfect audio sync across multiple devices
Show HN: Beatsync – perfect audio sync across multiple devices
24 by freemanjiang | 5 comments on Hacker News.
Hi HN! I made Beatsync, an open-source browser-based audio player that syncs audio with millisecond-level accuracy across many devices. Try it live right now: https://ift.tt/TRWga6i The idea is that with no additional hardware, you can turn any group of devices into a full surround sound system. MacBook speakers are particularly good. Inspired by Network Time Protocol (NTP), I do clock synchronization over websockets and use the Web Audio API to keep audio latency under a few ms. You can also drag devices around a virtual grid to simulate spatial audio — it changes the volume of each device depending on its distance to a virtual listening source! I've been working on this project for the past couple of weeks. Would love to hear your thoughts and ideas!

New top story on Hacker News: Show HN: I reverse engineered top websites to build an animated UI library
Show HN: I reverse engineered top websites to build an animated UI library
3 by armedin | 0 comments on Hacker News.
Looking at websites such as Clerk, I began thinking that design engineers might be some kind of wizards. I wanted to understand how they do it, so I started reverse-engineering their components out of curiosity. One thing led to another, and I ended up building a small library of reusable, animated components based on what I found. The library is built in React and Framer Motion. I’d love to hear your feedback

Show HN: Body Controlled 3D Dino Game
6 by NikoNaskida | 0 comments on Hacker News.
Hey HN, I am Niko. I've built this 3D Dino Game In browser using tech like three.js and MoveNet (tensorflow). Basically, it's a normal 3D dinosaur game with a twist: you need to actually perform actions irl to avoid obstacles. Duck to crouch, jump to jump, raise left hand - go left, raise right hand - go right. Game is using your phone/laptop camera to track your body movements and perform in-game actions. PS. Game is 100% client side and I don't record/track/use/save any of your data Hope you find it worth playing. (better play on PC) It's a 100% FREE browser game with no login! Please feel welcome to DM feedback or reply or anything!

Voice Flight – A voice-controlled flying game

Voice Flight is a browser game where players control a flying plane using just their voice. No login, no setup, just open and play. Players control the plane using the loudness and duration of their voice. The louder the voice, the higher the plane flies. https://ift.tt/nTC4OjS

New top story on Hacker News: Show HN: Qwen-2.5-32B is now the best open source OCR model
Show HN: Qwen-2.5-32B is now the best open source OCR model
16 by themanmaran | 3 comments on Hacker News.
Last week was big for open source LLMs. We got: - Qwen 2.5 VL (72b and 32b) - Gemma-3 (27b) - DeepSeek-v3-0324 And a couple weeks ago we got the new mistral-ocr model. We updated our OCR benchmark to include the new models. We evaluated 1,000 documents for JSON extraction accuracy. Major takeaways: - Qwen 2.5 VL (72b and 32b) are by far the most impressive. Both landed right around 75% accuracy (equivalent to GPT-4o’s performance). Qwen 72b was only 0.4% above 32b. Within the margin of error. - Both Qwen models passed mistral-ocr (72.2%), which is specifically trained for OCR. - Gemma-3 (27B) only scored 42.9%. Particularly surprising given that it's architecture is based on Gemini 2.0 which still tops the accuracy chart. The data set and benchmark runner is fully open source. You can check out the code and reproduction steps here: - https://ift.tt/qARtMhw... - https://ift.tt/L1tEk7h - https://ift.tt/nbydw0c
