Medical imaging software has significant lag performance

“Show HN: Holos – QEMU/KVM with a compose-style YAML, GPUs and health checks I got tired of libvirt XML and Vagrant's Ruby/reload dance for single-host VM stacks, so I built a compose-style runtime directly on QEMU/KVM. What's there: GPU passthrough as a first-class primitive (VFIO, OVMF, per-instance EFI vars), healthchecks that gate depends_on over SSH, socket-multicast L2 between VMs with no root and no bridge config, cloud-init wired through the YAML, Dockerfile support fo”

“Show HN: Resonate – Low-latency, high-resolution spectral analysis Last April I shared about my Resonate project here ( https://news.ycombinator.com/item?id=43694157 ) A lot has happened since: the work I presented in much more detail at last June's International Computer Music Conference (ICMC) got best paper award. I also gave a talk at the Audio Developer Conference in Bristol last November, the video is on YouTube). This year's work, which I recently presented at thi”

“Tell HN: One Medical Is a Nightmare I thought I'd relate an incredibly broken tech stack story, and its human consequences, to HN today. I used to have One Medical access through work, years ago, it was perfectly fine quality care, and then I stopped using it. I recently needed to find a replacement primary care and decided to try them again. Unfortunately, after a few weeks of initial care transfer and appointments, my account is now in a Sisyphean nightmare state, where it thinks I have a”

“OrthoRay – A native, lightweight DICOM viewer written in Rust/wgpu by a surgeon Hi HN, I am an orthopedic surgeon and a self-taught developer. I built OrthoRay because I was frustrated with the lag in standard medical imaging software. Most existing solutions were either bloated Electron apps or expensive cloud subscriptions. I wanted something instant, local-first, and privacy-focused. So, I spent my nights learning Rust, heavily utilizing AI coding assistants to navigate the steep learning cur”

“Show HN: Kiln – a fast, native batch image processor I was tired of outdated UIs and performance of similar tools. Nor did I want to write ImageMagick scripts every time I needed to resize/convert/watermark a folder with a few thousand images. It's a native desktop app built with C++23, Skia for rendering, libvips for image processing and my own cross-platform UI toolkit - no Electron/Qt. It allows building reusable pipelines: resize, convert, compress, watermark, sharpen, bl”

“Show HN: Cardcast.gg – Play paper Magic: The Gathering over webcam I've been building https://cardcast.gg , a web app for playing paper Magic: The Gathering remotely. You point a webcam at your play area and it identifies cards as you put them down. It's an alternative to Spelltable that I built for my friend group to play weekly with. The main technical difference is detection. Spelltable uses perceptual hashing; cardcast uses modern ViT backbones so it's much faster an”

“Show HN: Claude skill for Apple Instruments performance traces (iOS/Mac) I was running into scroll performance issues with a mac app I was building a few months back and I got frustrated with the manual instrument → trace → diagnose → fix loop, so I built a way for claude to do it automatically. Instruments Analyzer exports .trace files captured programmatically or via Instruments (file → save) into DuckDB with Parquet backing, giving your agents full SQL access to CPU profiling, animation hitch”
