Project mention: Show HN: Chili3d – A open-source, browser-based 3D CAD application | news.ycombinator.com | 2025-06-10
>Are they responsible for that Microsoft Office ribbon UI?
Well, that's the beauty of open source. Go read it.

>When I look at this, it's so sophisticated it just makes me feel think about the widening divide as far as AI skill gap goes. Was AI used?
I feel like this was the "So tell me about your father.." turn here , did you really care about the details or did you want to wax poetic about AI?

webr
The statistical language R compiled to WebAssembly via Emscripten, for use in web browsers and Node.
"{shiny} on my mobile" has been a recurring request from our clients for some time now. And it’s easy to see why: you might have a fantastic model or efficient data wrangling process, and you need people to access it on their smartphones—even in the middle of the forest with no cell connection (yes, that was an actual request from one of our clients). Yet, our response has always been the same: "Sorry, that’s not possible." {shiny} relies on a server, and since R can’t run directly on a phone, a remote server is required. That means an internet connection is necessary. And no, you can’t publish it to an app store. In recent months, however, something new has emerged—a development that R enthusiasts have been dreaming of for years: R, compiled for WebAssembly. If you’re unfamiliar with WebAssembly, think of it as a way to run R inside JavaScript. If you’re already acquainted with it, you’ll know it’s a bit more nuanced than that, but I’ll spare the technical details for now. This new tool is called webR.
