Nousb.co – A seamless multi-platform ephemeral file transfer webapp
Key technical point is that it does NOT rely on webRTC, which is not reliable enough on all browsers, and there are important file system APIs (ie. `showSaveFilePicker`) that are missing on most browsers to do actual file transfers, without storing the whole file in RAM first. The idea is to have something that is as multi-platform as possible, and can work on all browsers, even the embedded webviews in chat apps. And without app installation or account creation. To test it with a common case, which is transferring between a smartphone and a laptop: - Open https://NoUSB.co - Click…
What it does
In the maker’s words, at launch
Key technical point is that it does NOT rely on webRTC, which is not reliable enough on all browsers, and there are important file system APIs (ie. `showSaveFilePicker`) that are missing on most browsers to do actual file transfers, without storing the whole file in RAM first. The idea is to have something that is as multi-platform as possible, and can work on all browsers, even the embedded webviews in chat apps. And without app installation or account creation. To test it with a common case, which is transferring between a smartphone and a laptop: - Open https://NoUSB.co - Click the "Share link" button. - Scan the QR code with your phone or transfer the link to another computer. - Drag and drop large files; they'll instantly appear on the other side, regardless of size. - Click the download button on the receiving device. - Click the "Boost this!" button to unlock more transfer speed. - Close the tab and all sharing stop instantly Multiple devices can join the same virtual drive and share their own files. There's also a chat feature because if you click a sharing link from a messenger app, you will certainly end up trapped in their embedded webview with no way to get back to chat without disconnecting. For more technical details: https://dev.to/stant/nousbco-yet-another-file-transfer-tool-... Please test it and let me know how it went for you. Thanks! webRTC is actually implemented as an experimental feature, you'll need to add `&rtc=1` on both sides to enable it. Only chrome based browsers that implement `showSaveFilePicker` can be the downloading end.

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

I'm a big fan of the BBC podcast In Our Time -- and (like most people) I've been playing with the OpenAI APIs. In Our Time has almost 1,000 episodes on everything from Cleopatra to the evolution of teeth to plasma physics, all still available, so it's my starting point to learn about most topics. But it's not well organised. So here are the episodes sorted by library code. It's fun to explore. Web scraping is usually pretty tedious, but I found that I could send the minimised HTML to GPT-3 and get (almost) perfect JSON back: the prompt includes the Typescript definition. At the same time I…
