    I built a tool to show how people trained for your goal marathon time2025 · getfast.ai · ▲6

    The idea for this came from wanting something like Naviance (let’s you see the GPA and test scores of admitted students for a given college) for marathon running. In general, we’re working on making your running data more useful, and our newest tool, called, "Marathon Cohorts," gives you stats about runners who finished a marathon in a given time. You pick a marathon time / cohort and then look at - Weekly training mileage - Fastest 5k, 10k, half marathon, and 30k during training. You can adjust the cohorts to see how these values change as the marathon time gets slower / faster.…

  • Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…
