Show HN: isometric.nyc – giant isometric pixel art map of NYC

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: https://ift.tt/hjN4GWQ

New best story on Hacker News: Show HN: ChartGPU – WebGPU-powered charting library (1M points at 60fps)

Show HN: ChartGPU – WebGPU-powered charting library (1M points at 60fps)

Creator here. I built ChartGPU because I kept hitting the same wall: charting libraries that claim to be "fast" but choke past 100K data points. The core insight: Canvas2D is fundamentally CPU-bound. Even WebGL chart libraries still do most computation on the CPU. So I moved everything to the GPU via WebGPU: - LTTB downsampling runs as a compute shader - Hit-testing for tooltips/hover is GPU-accelerated - Rendering uses instanced draws (one draw call per series) The result: 1M points at 60fps with smooth zoom/pan. Live demo: https://chartgpu.github.io/ChartGPU/examples/million-points/ Currently supports line, area, bar, scatter, pie, and candlestick charts. MIT licensed, available on npm: `npm install chartgpu` Happy to answer questions about WebGPU internals or architecture decisions.

Countless voiceless people sit alone every day and have no one to talk to, people of all ages, who don't feel that they can join any local groups. So they sit on social media all day when they're not at work or school. How can we solve this?

Stop Doom Scrolling, Start Doom Coding: Build via the terminal from your phone

I used Tailscale, an old laptop, Claude Code, and Termius to code from my phone anywhere I have Internet connection. Great for parties where you rather be home tinkering.

New best story on Hacker News: Show HN: OpenWorkers – Self-hosted Cloudflare workers in Rust

Show HN: OpenWorkers – Self-hosted Cloudflare workers in Rust
327 by max_lt | 105 comments on Hacker News.
I've been working on this for some time now, starting with vm2, then deno-core for 2 years, and recently rewrote it on rusty_v8 with Claude's help. OpenWorkers lets you run untrusted JS in V8 isolates on your own infrastructure. Same DX as Cloudflare Workers, no vendor lock-in. What works today: fetch, KV, Postgres bindings, S3/R2, cron scheduling, crypto.subtle. Self-hosting is a single docker-compose file + Postgres. Would love feedback on the architecture and what feature you'd want next.

Paste in my prompt to Claude Code with an embedded API key for accessing my public readonly SQL+vector database, and you have a state-of-the-art research tool over Hacker News, arXiv, LessWrong, and dozens of other high-quality public commons sites. Claude whips up the monster SQL queries that safely run on my machine, to answer your most nuanced questions. There's also an Alerts functionality, where you can just ask Claude to submit a SQL query as an alert, and you'll be emailed when the ultra nuanced criteria is met (and the output changes). Like I want to know when somebody posts about "estrogen" in a psychoactive context, or enough biology metaphors when talking about building infrastructure. Currently have embedded: posts: 1.4M / 4.6M comments: 15.6M / 38M That's with Voyage-3.5-lite. And you can do amazing compositional vector search, like search @FTX_crisis - (@guilt_tone - @guilt_topic) to find writing that was about the FTX crisis and distinctly without guilty tones, but that can mention "guilt". I can embed everything and all the other sources for cheap, I just literally don't have the money.
