- IMI made a worldwide sexual life dashboard2025 · worldsexmap.com · ▲62
The idea is to share data-based insights about sexual life I’ve worked in SexEd startups, and it’s wild that humanity doesn’t have this data. Most major academic studies have focused on sex primarily from a health and reproduction perspective, leaving many important and interesting questions unexplored (for many reasons) To promote transparency, the anonymous data will be open-sourced, allowing researchers, students and anyone interested to analyze it

That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

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…
