Sunrise, sunset and golden hour, anywhere on a map
What it does
Tap any point on the map and see the full solar day there: sunrise, sunset, twilight, golden hour, live sun position. A time slider scrubs through the day and the sun marker, shadow arrow and daylight wedge on the map move with it. Zoom out to see the global day/night line sweep across the earth. 500 city pages plus dedicated pages for today, tomorrow, the next eclipse and the next solstice. Handles polar regions, every time zone and DST. Free, no signup, open source.

- DTDaylight – track sunrise / sunset times in your terminal2025 · github.com · ▲79
I love the sunlight and dread the long, dark winter evenings of Northern Europe. I often look up sunrise / sunset times and count off the days until the darkness is gone.

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…
