heyhey – Building a Linktree-like app taught me more than college
Hello Hacker News! HEYHEY is a service that tries to bridge the siloed platforms of the modern-day internet and be where people come to search for others. So far, I've spent about 2 months developing it, and as a college student, it honestly helped me learn more about computer science than any undergrad course we have. Also, after getting the inspiration from HN, I wanted to prove to myself that, in 2022, anyone could build a full-fledged web service. Thanks to its modern-yet-traditional infrastructure, HEYHEY is costing me about 0 dollars a month to run (so far!). I really wanted to keep…
In plain words
HEYHEY is a service that consolidates scattered online profiles into a single searchable hub, similar to Linktree. It allows users to create profiles and discover others across fragmented internet platforms. Built by a college student in two months, the service operates at no cost using traditional web infrastructure with HTML and CSS, requiring no JavaScript. It functions as a simple yet complete web application designed for ease of use and accessibility.

Hello Hacker News! HEYHEY is a service that tries to bridge the siloed platforms of the modern-day internet and be where people come to search for others. So far, I've spent about 2 months developing it, and as a college student, it honestly helped me learn more about computer science than any undergrad course we have. Also, after getting the inspiration from HN, I wanted to prove to myself that, in 2022, anyone could build a full-fledged web service. Thanks to its modern-yet-traditional infrastructure, HEYHEY is costing me about 0 dollars a month to run (so far!). I really wanted to keep the service simple but functional. So naturally, I tried to stay away from a JS-based front-end. Instead, HEYHEY uses simple HTML pages with modern CSS and forms to function (you can disable JS!). Last week, I silently turned on registers, and if you register today, you will have a 10% chance to get Pro for life — it enables custom usernames (heyhey.to/[username]) and rich themes. I am not trying to take over the "Linktree space" nor trying to build a unicorn startup. After making HEYHEY presentable, I just wanted others to have access to it as well. I hope to keep developing HEYHEY so that it can further integrate with other social platforms while staying lightweight and functional. Would love to hear your feedback!

- HBHackerNewt – Breadth-first exploring HN client for iOS2025 · apps.apple.com · ▲68
I made a HN client that allows you to explore comments in a breadth-first manner. Compared to the classic depth-first approach, it works much better for the larger threads - you don't lose the context and can easily skip discussions you're not interested in.

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:…

Hi HN community, I’m Zach, founder and CEO of Warp, and am excited to show you Warp, a fast Rust-based terminal that’s easy to use and built for teams. As of today, Warp is in public beta and any Mac user can download it. It works with bash, zsh, and fish. The terminal’s teletype-like interface has made it hard for the CLI to thrive. After 20 years of programming, I still find it hard to copy a command’s output; I always forget how to use `tar`; and I always have to relearn how to move my cursor. To fix fundamental accessibility issues, I believe we need to start innovating on the terminal,…
