DotSleep

What it does

I built DotSleep after realizing I could sleep 8 hours and still wake up exhausted. Most sleep apps focus on sleep duration, but I cared more about accumulated fatigue and inconsistent sleep schedules. DotSleep tracks sleep debt, estimates fatigue levels, and suggests when you should realistically go to bed to recover. Started as a small side project because I wanted to figure out why I was always tired 😅

  I made an app to help insomniacs learn how to sleep again2022 · slumber.one · ▲94

  Hi HN! I suffered from chronic insomnia for over a year and tried everything from cutting coffee, blocking blue light, to taking melatonin and antihistamine, but couldn’t find anything that worked. I even bought a $500 research-grade EEG device to track my sleep, which was honestly kind of depressing because it showed that I was sleeping less than 4 hours per night for weeks straight. In the day, it took an immense amount of energy for me to perform even the most mundane of tasks, such as doing my laundry or ordering groceries. At night, I felt an overwhelming sense of loneliness and…

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  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…
