Offline SOS signaling+recovery app for disasters/wars
A couple of months ago, I built this app to help identify people stuck under rubble. First responders have awesome tools. But in tough situations, even common folks need to help. After what happened in Myanmar, we need something like this that works properly. It has only been tested in controlled environments. It can also be improved; I know BLE is not _that_ effective under rubble. If you have any feedback or can contribute, don't hold back.
Offline SOS signaling+recovery app for disasters/wars launched on April 1, 2025 with 163 votes, #242 of 7,818 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
This app helps locate people trapped under rubble during disasters and conflicts by enabling SOS signaling and recovery coordination. Designed for civilians and first responders in emergency situations, it uses Bluetooth Low Energy to facilitate communication when conventional methods fail. The tool is currently in early stages with testing limited to controlled environments, and the creator acknowledges technical limitations and welcomes feedback for improvements.

Offline SOS signaling and recovery app for wars and disasters (iOS & Android) — like a digital flare-gun. - igatha/flare-gun
Igatha is an open-source SOS signaling and recovery app designed for war zones and disaster areas, enabling offline emergency communication when traditional networks fail. With disaster detection, Igatha will now run in the background, monitoring your device's sensors. When a potential disaster is detected, you'll receive an " Are you okay? " notification: No internet or GPS is required, preventing signal jamming or manipulation. Responders can toggle additional signals, like flashlight or vibration, remotely. (planned feature) Disaster detection triggers when multiple sensors simultaneously detect abrupt changes. Location permissions are required for " Disaster Detection ". Igatha…from github.com

I have a bad memory and can't memorize some important numbers, so I created this project. I've always been concerned about being without my phone (getting robbed - which is common in Brazil - running out of battery, having it break, etc.), so I decided to create a page that sends SMS messages (LLM-summarized) and emails with more detailed information such as geolocation, IP address, and the full message. It’s a simple page that allows sending one or more messages, with recipients being myself and other people - for example, in case I or they need help or need to communicate something…
Incident/OpsJan 2026 · incidentops.io · ▲59I've been an on-call engineer at startups where "incident management" meant someone panic-creating a Slack channel called #fire-fire-fire, or all incidents handled in the #incidents channel at the same time... and the postmortem was whatever someone remembered to write in Notion three days later. So I built a Slack bot to fix my own workflow. Figured I'd share it. What it does: "/incident start sev2 API latency spike" creates a dedicated channel, invites whoever's on-call, pins the details, and starts recording a timeline. When you run "/incident resolve", it uses GPT-4 to analyze…

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
