BoxVision
Smart QR labels for your moving boxes — free to start
What it does
Moving is chaos. BoxVision fixes the part nobody talks about: you seal a box and immediately forget what's inside. Each box gets a QR code. Scan it and see the full contents — from any phone, no install needed. Add items by typing, photo, or voice. Organize by room. Mark urgent boxes. It's a PWA — works offline, installs like an app. Free: unlimited boxes & QR codes. Pro (coming soon): cloud sync & backups.

- IBI built an app to use a QR code as my doorbell2024 · dingdongdoorbell.com · ▲140
I didn’t have a doorbell before (multiple reasons) and my house feels unwelcoming without one. So I built a doorbell app that uses a QR code - visitors scan the QR code to ring the doorbell and I get notified on my phone. Here is an example of the QR code I have on my door. You can scan it and say hello: https://www.thebacklog.net/img/2024/10/show-hn.png This was also a great excuse to build my first app for Android and iPhone. I’d love to get some feedback before I spend more time polishing the app. Please try it out and feel free to ask me any questions! No…

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…
