2, 3, 5, 7 can only form 1×N rectangles. Place them first — their shape is forced. A "6" can be 1×6, 2×3, 3×2, or 6×1. Learn which shapes fit where. Start with smaller grids to build pattern recognition before tackling larger puzzles. If placing a rectangle blocks another number, it's wrong. Think one step ahead. Stuck? Enter your puzzle and get the unique solution instantly. Each rectangle's area must equal its number. No more, no fewer. A cell numbered "2" on a Shikaku grid is the strongest clue — it can only be a 1×2 or 2×1 rectangle, no thinking required. Start every puzzle by scanning for primes first. Then check if those rectangles reveal new forced placements for neighboring numbers.…from gridpaw.com

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:…

I made OwnTime to balance between competing priorities in my life. The idea is based on two main influences: the concept of "roles" from "The 5 Choices" (2015), and my repeated failure to effectively implement time blocking due to the necessary flexibility in my role. The app allows you to define time budgets, which are not much more than a few mutually exclusive countdown timers. The UX is essentially that of a chess clock for an arbitrary number of players with configurable time. The whole point of the app is to kick you out of the running role/priority when its time is up. One…
