zMkPanicSoS

Open-source emergency video recorder (500Kb, Self-hosted)

What it does

zM SOS GUARD is a forensic Android recording protocol. I built it for journalists and activists who need absolute data sovereignty. No cloud, no bloat, no tracking. The 500Kb APK uses native code to fragment video into 20s blocks, pushing them directly to your private Python server. Designed to bypass battery kills and ensure forensic persistence (tested up to Android 16). Fully open-source, auditable, and built for transparency. Check the source on GitHub and see the documentation on my site.

    I made a tiny camera with super long battery life2024 · toaster.llc · ▲843

    Hey HN! A few years ago someone kept trying to steal my motorcycle, so I decided to make a small camera with really long battery life to catch them. The hardware/software is totally open source, but the companion app only supports macOS currently. (I'm a big fan of native apps, and didn't want to block releasing on Linux/Windows support.) I wrote some blog posts about the process: PCB design: https://toaster.llc/blog/pcb Enclosure design: https://toaster.llc/blog/enclosure Image pipeline:…

    Rem: Remember Everything (open source)2023 · github.com · ▲555

    An open source approach to locally record everything you view on your Apple Silicon computer. Note: Relies on Apple Silicon, and configured to only produce Apple Silicon builds. I think the idea of recording everything you see has the potential to change how we interact with our computers, and believe it should be open source. Also, from a privacy / security perspective, this is like... pretty scary stuff, and I want the code open so we know for certain that nothing is leaving your laptop. Even logging to Sentry has the potential to leak private info.

    Open-source private home security camera system (end-to-end encryption)May 2026 · github.com · ▲137

    Hey everyone, I previously introduced an open source private home security camera in 2024, which uses OpenMLS for end-to-end encryption: https://news.ycombinator.com/item?id=42284412. It was called Privastead then and it's now renamed to Secluso. John Kaczman found my project from here and has been working on it with me over the last year and half. We've made a lot of improvements to the software, which we would like to share with you: - You can now set this up on your Raspberry Pi in less than 5 minutes with no technical expertise using our easy-to-use GUI deploy tool. We've…

    Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
