Mapping DNS
I learned about LOC records some time around the start of the year from a post here on hackernews, and I've been slightly obsessed with the idea of mapping them ever since - and now I've finally done so! There ended up being a few more than I expected, but still very much within reasonable bounds.

Hey HN, Last weekend I vibe-coded a cool website that lets you do easy DNS record lookups. I know you can just use dig or nslookup, but oftentimes I'm too lazy to remember the syntax, and there are less technical users who need to manage DNS entries but aren't comfortable with the command line. We debug customer DNS issues often at ImprovMX, and we typically link to tools like mxtoolbox.com to point out DNS record issues. But those tools seem quite bloated and from the 2000s. I wanted something super clean & simple, and there were a few features I thought were ergonomically needed but…

Hey HN! We built DNS Directory (https://dnsdirectory.com), a free, searchable database of public DNS servers with live monitoring every 10 minutes. We needed to find an up-to-date list of DNS servers used by carriers around the world for a proxy fingerprinting / web-scraping project but we were shocked to find that it didn’t exist so we built it ourselves in an internal Hackathon We’re adding more features but so far we: Test 77K+ servers every ~10 minutes Allow filtering by uptime, location, security features (ad blocking, malware protection, DNSSEC) Show info on IPv6…

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:…

Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
