DeepDocs2025 · deepdocs.dev · ▲132In my 15+ years as a developer, one of the most frustrating problems I've seen across teams is outdated documentation. I’ll be honest, I skip it myself. You ship a feature and move on. Then a month later, someone is onboarding or debugging and runs into stale docs that no longer reflect the code. I tried fixing this with tools like Swagger and Sphinx-autodoc, but they only work for narrow use cases like OpenAPI or annotations. They don’t help with the high-level stuff like onboarding tutorials, SDK guides, or user-facing examples. You still have to keep things like docstrings in sync, and…

It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
