Yotsu
Four daily logic puzzles, no ads, no tracking, no account
What it does
Hi hunters, I've been working on Yotsu, it gives you four logic puzzles a day (Shikaku, Akari, Binairo, Sudoku), and that's it. No fifth puzzle, no streak manipulation, nothing designed to keep you scrolling. A few things I cared about when building it: - No ads, ever - No account or sign-up - Nothing tracked — all your data stays on your phone - Works fully offline It's a solo project. I'm a designer, not a developer by trade, so feedback is very welcome! Especially if something feels off.

It's like a mix between Picross (Nonograms) and Polyominoes. It's a minimalist puzzler which has no text, no tutorials (none required) and no ads set in a relaxing environment. App Store: https://itunes.apple.com/gb/app/shapeuku-shape-puzzle-game/i... Play Store: https://play.google.com/store/apps/details?id=com.dtbgames.s... I have a bulk load of Android promo codes to give away, so if you'd like one let me know! (Sorry iOS users, I have no free codes left!)

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 might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…
