Show HN: Beatsync – perfect audio sync across multiple devices 38 by freemanjiang | 15 comments 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://www.beatsync.gg/ 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! on Hacker News. Hi HN!

Show HN: I reverse engineered top websites to build an animated UI library 8 by armedin | 1 comments 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 on Hacker News. Looking at websites such as Clerk, I began thinking that design engineers might be some kind of wizards.

Show HN: Aqua Voice 2 – Fast Voice Input for Mac and Windows 27 by the_king | 7 comments Hey HN - It’s Finn and Jack from Aqua Voice ( https://withaqua.com ). Aqua is fast AI dictation for your desktop and our attempt to make voice a first-class input method. Video: https://withaqua.com/watch Try it here: https://withaqua.com/sandbox Finn is uber dyslexic and has been using dictation software since sixth grade. For over a decade, he’s been chasing a dream that never quite worked — using your voice instead of a keyboard. Our last post ( https://news.ycombinator.com/item?id=39828686 ) about this seemed to resonate with the community - though it turned out that version of Aqua was a better demo than product. But it gave us (and others) a lot of good ideas about what should come next. Since then, we’ve remade Aqua from scratch for speed and usability. It now lives on your desktop, and it lets you talk into any text field -- Cursor, Gmail, Slack, even your terminal. It starts up in under 5...

Show HN: iPhone 2005 weird "Blob Keyboard" simulator 14 by juliendorra | 3 comments Hi HN, I teach tech design history, and one of the key stories I cover is the development of the original iPhone keyboard by Ken Kocienda. Reading about it in his book "Creative Selection" is great, but I wanted my students (and now you!) to actually feel this step in the process. So, I built a web simulator of the "Blob Keyboard", Kocienda's very first attempt at a touchscreen keyboard that actually works, from September 2005: Try the Blob Keyboard: https://juliendorra.github.io/blob-keyboard-simulator/blob-k... - Tap for the middle letter - Swipe left or right for the side letters More on the github repo: https://github.com/juliendorra/blob-keyboard-simulator The Blob Keyboard prototype emerged during a UX crisis for iPhone team (their software keyboard just didn't work at all, fingers being too big, and the Newton failure loomed over them), highlighting how inno...

Show HN: Hatchet v1 – a task orchestration platform built on Postgres 11 by abelanger | 2 comments Hey HN - this is Alexander from Hatchet. We’re building an open-source platform for managing background tasks, using Postgres as the underlying database. Just over a year ago, we launched Hatchet as a distributed task queue built on top of Postgres with a 100% MIT license ( https://news.ycombinator.com/item?id=39643136 ). The feedback and response we got from the HN community was overwhelming. In the first month after launching, we processed about 20k tasks on the platform — today, we’re processing over 20k tasks per minute (>1 billion per month). Scaling up this quickly was difficult — every task in Hatchet corresponds to at minimum 5 Postgres transactions and we would see bursts on Hatchet Cloud instances to over 5k tasks/second, which corresponds to roughly 25k transactions/second. As it turns out, a simple Postgres queue utilizing FOR UPDATE SKIP LOCKED doesn’t cut it at this scal...

Show HN: Qwen-2.5-32B is now the best open source OCR model 8 by themanmaran | 1 comments 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://getomni.ai/blog/benchmarking-open-source-models-for...
