Crisis Connect
Offline emergency messaging without internet
What it does
Crisis Connect helps people stay reachable when networks fail. It uses Bluetooth-based device-to-device communication to send encrypted messages, voice notes, live location, and SOS signals to nearby phones — without internet, SIM, cellular signal, or local infrastructure.

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.

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…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
