The UNIX List
Henderson/smartPhone video
This sixteen-minute video module describes a method whereby any member of an Emergency Room ("ER") or Intensive Care Unit ("ICU") multispecialty team can verify that the pH value that the Clinical Lab has provided to them within a patient's Arterial Blood Gas (or "ABG") report is compatible with the Henderson Hasselbalch Equation. This task can be completed within seconds by using the Calculator "app" bundled within both Unix-based and Android-based smartphones. This module incorporates a Case
Show HN: Qwen-Image-Edit-2512 – Consistent multi-character image editing
Most image editing models struggle when a scene contains multiple subjects—editing one person often leads to "identity bleeding" or unintended changes to others.Qwen-Image-Edit-2512 is specifically optimized for complex, multi-subject editing. It allows you to modify specific characters or elements while maintaining the visual consistency of everyone else in the frame.Why it’s different:Identity Preservation: Change the clothes or actions of "Character A" without altering the
A quantum-resistant RNG powered by collective human entropy
Hi HN,I’m not a professional developer, but I’ve been obsessed with the idea of "Human Entropy." With the rise of quantum computing, I started wondering: Can we create a random sequence that no machine can predict because its source is the unpredictable nature of human behavior?I built this web app using Flutter and Firebase. It's a simple idea: users perform actions on the web client, and those unique interaction hashes are sent to a secure Firestore pool. A server-side Cloud Fun
Show HN: A minimalist LLM plugin for tmux
tmux-llm is an experimental LLM user interface that is: - minimal (no chat, no history, no replies, not even an input field)
- universal (available in all your terminal applications)
- transparent (the only context sent to an LLM is what you see on the screen)
Basically, you can hit Ctrl+G at any time and get a tmux pop-up with an LLM's reply based on whatever is currently in your terminal. If you want, you can also select a specific part of the terminal contents. That's it.Clear
Show HN: Vibora – Run Claude Code remotely, close your laptop, keep shipping
I built Vibora because I wanted more than a UI to orchestrate multiple Claude Code sessions — I wanted to kick off work, close my laptop, and check progress from my phone while I'm out. You don't need to run it remotely. Vibora is still incredibly useful running on your laptop. But once you get used to telling Claude to work on a feature, notify you when it's finished, and getting that first notification 20 minutes later — you won't want to go back.Vibora is a self-hosted web
Show HN: Text-to-3D Motion Generator (Hunyuan 1.0 wrapper)
Hi everyone,I built a UI for the new open-source Hunyuan Motion model to generate 3D animations from text:

I'm trying to bridge the gap between "cool AI demo" and "useful game dev tool".Question for 3D devs/animators:If you were to use this in production, what is the single biggest missing feature?1. Export Pipeline: Auto-conversion to FBX for Unity/Unreal?

Unix
UnixUnix (The Unix Time-Sharing System) – an operating system developed from 1969 at Bell Labs (UNIX System Laboratories, USL) by Dennis Ritchie and Ken Thompson. It gained widespread popularity in the 1970s and 1980s, spawning numerous variants and implementations. https://archiveos.org/unix/
Show HN: Tidy- A minimal directory organizer I built to clean my downloads
I built tidy for myself because my Downloads folder and various project directories were very cluttered. I wanted a CLI tool, or a script to do that, but had little success, so I built my own. It’s written in Go and uses the Charm (Bubble Tea) TUI framework... Tested working on WSL and it works great for moving all files to their extension based directories easily. I've found it really helpful for keeping my WSL and Linux environments clean. Do give it a go!
Ask HN: How are you using Nvidia cards on Linux with its VRAM issues?
I recently discovered that on Linux, NVIDIA GPUs will not seamlessly access system memory if the GPU's memory gets full where as on Windows it does.After 25 years on Windows I recently switched to Linux over the holiday break and came across this with my GeForce 750 Ti which only has 2 GB of GPU memory.After opening a few Firefox and Ghostty terminals (both apps are hardware accelerated), I notice system instability and things crash or my Wayland compositor (niri) starts failing in unpredic

Show HN: Mindwtr – Local-First GTD App (Tauri, React Native, Rust)
Hello HN,I built Mindwtr because I wanted the speed and polish of apps like Things 3, but with the data ownership of Emacs Org-mode.It is an open-source (MIT/AGPL), local-first implementation of the Getting Things Done (GTD) methodology.The Stack:
- Desktop: Tauri v2 (Rust) + React. It runs heavily on Arch Linux (my daily driver).
- Mobile: React Native (Expo) on Android.
- Sync: It treats the file system as the source of truth. Data is stored in JSON/TOML, allowing you to sync via Syn
Show HN: A Simple CLI Utility Around Git Worktree for Running Parallel Agents
I built gw, a small CLI utility that wraps git worktree to make running parallel coding agents less painful.When you run multiple agents against the same repo, git worktree is usually the right tool — but the workflow is a bit clunky.gw provides simple commands like gw add, gw cd, gw del, and gw ls, plus a gw status command to quickly see the state of all worktrees at once.It works on macOS, Windows, and Linux, and installation is straightforward via brew, scoop, or a simple install.sh.If you re
