fx-upscale – Metal-powered spatial video upscaling
Hi! This is a quick lil CLI I've created for upscaling videos using Apple's MetalFX (https://developer.apple.com/documentation/metalfx). There are a few improvements I plan to make, such as HDR support and a progress bar, but if it sounds interesting, please give it a try and let me know what you think!
In plain words
fx-upscale is a command-line tool for upscaling videos using Apple's MetalFX technology. Designed for developers and video professionals on Mac, it leverages GPU acceleration to enhance video resolution. The tool is currently in early development with planned features including HDR support and progress tracking.

- ASApple's SHARP running in the browser via ONNX runtime webMay 2026 · github.com · ▲185
Hi HN, author here. SHARP is Apple's recent single-image 3D Gaussian splatting model (https://arxiv.org/abs/2512.10685). Their reference code is PyTorch + a pretty heavy pipeline; I wanted to see if it could run in a browser with no server hop, so I exported the predictor to ONNX and ran it via onnxruntime-web with the WebGPU EP. What works: drop in an image, get a .ply you can download or preview live, all on your machine — your image never leaves the tab. The model is large (~2.4 GB sidecar) so first load is slow on a cold cache, but inference itself is a few seconds on…

Hi HN! I’m proud to share that we have built a real 3rd party iMessage client for Android. We did it by reverse engineering the iMessage protocol and encryption system. It's available to download today (no waitlist): https://play.google.com/store/apps/details?id=com.beeper.ima and there's a technical writeup here: https://blog.beeper.com/p/how-beeper-mini-works. Unlike every other attempt to build an iMessage app for Android (including our first gen app), Beeper Mini does not use a Mac server relay in the cloud. The app connects directly to Apple…

Hey! I made Heynote entirely for my own use case. For many years, I always had an Emacs instance running with the scratch buffer open, even long after I had abandoned Emacs as my programming editor in favor of more recent IDE:s. The simplicity of having just one big scratch buffer appeals to me, but I still want to separate the different things I jot down somehow (without using tabs or similar). Previously, my solution was to insert a bunch of blank lines between the notes, but hitting C-A would still select the entire buffer. That's why I came up with the concept of "blocks", which turned…
