• Video uploader for React/RN 0 open listings

  discussion=https://news.ycombinator.com/item?id=49741778, title=Show HN: Video uploader for React/RN – drop in or headless UI, any back end, Universal Video Uploader is an open source React/React Native component library for adding video upload flows to your app. It handles the UX and background mechanics for single or multi-video upload flows: upload state, file queue, concurrency, per-file progress, abort/retry, validation, and backend communication for async processing. It comes with a composable and customizable UI, or you can go headless and use the core hooks to build your own. You can connect it to any backend via the adapter interface, and it ships with a prebuilt adapter for Hyperserve (a video backend API I built). I've had to build this kind of thing a few times and it's more complex than it seems, I wanted to try making something drop in that is still flexible and comprehensive. I'm currently using it as the dashboard uploader for Hyperserve and so far it's working great. Try it at https://videouploader.fyi . There's full docs with live demos for every component, plus working Next.js and Expo examples you can run. I'd appreciate any feedback on it if you have any!

  discussion=https://news.ycombinator.com/item?id=49695678, title=Show HN: Vigilator – human-in-the-loop layer for AI agents, Hi - I'm Noah, a student working out of the UK & I've been building Vigilator for the past couple of months, Vigilator provides an agnostic solution for handling interrupts and observing agents as they work. I was inspired to build Vigilator after I realised as teams roll out AI agents across organisations there's no consistent way to interrupt an agent mid-task, get a human decision, and resume - especially when multiple people can be responsible for weighing in on the decisions. Vigilator provides a dashboard, where you and your teammates can join a virtual organisation - from here you can use our Py/TS SDK or simply make API calls yourself - then from here tool calls can be approved/reviewed/denied and agents can be monitored as they work. We provide a workload management system meaning that you can have multiple team members at once handling interrupts and watching agents as they work. Vigilator is still early, while Vigilator is framework agnostic I've primarily focused on adding support and examples for Mastra, Langchain Deep Agents and Langgraph - and I would love feedback, particularly from people running agents in production at scale. try it: https://vigilator.ai Docs: https://docs.vigilator.ai (conceptual overview: https://docs.vigilator.ai/concepts ) If you would like to get in contact feel free to shoot me an email at [email protected]

• Vim-like, hyper-efficient, LLM power tool 0 open listings

  discussion=https://news.ycombinator.com/item?id=49746030, title=Show HN: Vim-like, hyper-efficient, LLM power tool - 20-80k tokens not 350k+, I built a focused TUI tool for efficient parallelized tasks, early independent testers expressed 90%+ API savings and more direct results. This is accomplished by user smaller context windows, hybrid client-side compaction, tool compaction, and system nudges (to avoid polluting the base prompts). My Shell features: - Vim-inspired keybindings, your keys never have to leave the keyboard (some mouse control supported as well) - Custom Markdown, LaTeX, and Mermaid rendering support - On-demand subagents with LLM-directed context handoff - Thread pooling, client-side compaction, tool compaction - Supports Powershell without a degraded experience; also support VGA/VESA mode, run even when GPU drivers break! - Single bundle, no external packages required It’s opinionated, terminal-first, Vim-inspired; if that’s not for you, I have a web chat and a desktop app coming soon

• WFCLab 0 open listings

  discussion=https://news.ycombinator.com/item?id=49744376, title=Show HN: WFCLab – Interactive Wave Function Collapse Explorer (With Source), Author here. WFCLab is a desktop app I built in Godot 4 for experimenting with example-based procedural generation, specifically wave function collapse. The workflow is: load a source image, decompose it into tiles and constraints, review the resulting tile set and constraints and make a limited set of changes, then run synthesis to generate new layouts that follow the same local rules without copying the original. Some context on why I built it this way: Most WFC implementations I found were either libraries you call from code or one-shot scripts that take an image and print an output. I wanted something where the intermediate steps were visible, so I could examine them and mess around with them. Thus, when synthesis fails or produces garbage, you can go looking for the cause and mess around with the settings until you figure it out, and can better track down the source instead of leaving it hidden away inside a huge function. So WFCLab exposes each stage as a separate view you can inspect and tweak. Current state: the full pipeline works end to end, and there are sample images and saved projects in the repo so you can try it without your own art. It is very much a work in progress. The UI is functional rather than polished, and I have not tested it on a wide range of source images. Known limitations: - Performance drops on large output sizes, especially with backtracking enabled - Constraint editing is list-based, not a visual graph editor yet - Only 4-way and 8-way adjacency, no custom direction sets - No built in image editing at all. - Can't actually export output images yet. Is anyone interested in this? Should I dedicate additional effort to developing it, or focus my efforts elsewhere? If you have used WFC before, what would you want to be able to control or inspect that this does not expose?

• What Just Pinged Me? 0 open listings

  discussion=https://news.ycombinator.com/item?id=49689178, title=Show HN: What Just Pinged Me?, My wife kept getting some random-seeming notification sounds on her macbook that we couldn't identify - a little quarter second "bloop" that would play and then go away without any trace we could find. So I made (prompted) this app that will listen to the audio on the system and identify the sound. It will identify system sounds and use system logs to try to work out what caused it, it will tell you which apps were making sounds when the sound is played, it will look in app bundles for sound files that contain the sound it heard. If the source is the web browser and you install the bundled browser extensions it will tell you the name of the tab that played it.

  discussion=https://news.ycombinator.com/item?id=49726812, title=Show HN: Who-GPU, a simple monitoring tool to view GPU usage across machines, At my university, we have a bunch of GPU machines, but no scheduling system. So you would have to manually SSH into them and check which ones are in use before you start a job. So, I made a CLI to automate that for me. That evolved into a dependency-free webpage as well. It works on Linux, Mac, and Windows (windows needs Git Bash.) If you regularly SSH into machines to check their GPU usage, you are the perfect user! I'd love your feedback.
