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.

Show HN: yolo-cage – AI coding agents that can't exfiltrate secrets

I made this for myself, and it seemed like it might be useful to others. I'd love some feedback, both on the threat model and the tool itself. I hope you find it useful!

Backstory: I've been using many agents in parallel as I work on a somewhat ambitious financial analysis tool. I was juggling agents working on epics for the linear solver, the persistence layer, the front-end, and planning for the second-generation solver. I was losing my mind playing whack-a-mole with the permission prompts. YOLO mode felt so tempting. And yet.

Then it occurred to me: what if YOLO mode isn't so bad? Decision fatigue is a thing. If I could cap the blast radius of a confused agent, maybe I could just review once. Wouldn't that be safer?

So that day, while my kids were taking a nap, I decided to see if I could put YOLO-mode Claude inside a sandbox that blocks exfiltration and regulates git access. The result is yolo-cage.

Also: the AI wrote its own containment system from inside the system's own prototype. Which is either very aligned or very meta, depending on how you look at it.

Director Gore Verbinski: Unreal Engine is the greatest slip backwards for movie

The article discusses director Gore Verbinski's criticism of Unreal Engine, claiming it has led to a regression in movie CGI quality compared to traditional rendering techniques. Verbinski argues that the ease of use and accessibility of Unreal Engine has resulted in a loss of artistic control and a decline in the overall visual fidelity of CGI in films.

Show HN: QTap DevTools – Chrome-style encrypted traffic inspector for Linux

Show HN: QTap DevTools – Chrome-style encrypted traffic inspector for Linux

Hi HN, I'm Tyler Flint. Eight months ago we shared qtap here (https://news.ycombinator.com/item?id=43928118).

Today we're releasing DevTools - a browser-based interface that gives you the Chrome Network tab experience for server-side HTTP/S traffic.

The problem: You're debugging a production issue. An external dependency is returning errors. Your logs say "request failed" but not what was actually sent. Adding debug logging means redeploying and restarting services - which takes time and often changes the conditions you're trying to debug. tcpdump shows encrypted blobs. Setting up mitmproxy means certificates, restarts, reconfiguration.

Our solution: install qtap, enable DevTools, open localhost:10001 in your browser. You're now watching live HTTP/S traffic - every request, response, header, body - in plaintext. No restarts, no certificates, no code changes.

It works by hooking into TLS libraries (OpenSSL, Go crypto, Java SSL, Node.js, etc) via eBPF before encryption happens.

Getting started:

    # Option A: Install script (inspect it first if you prefer)
    curl -s https://get.qpoint.io/install | less
    curl -s https://get.qpoint.io/install | sudo sh
    sudo qtap --enable-dev-tools
If you're (rightly) skeptical of curl | sh, grab the binary directly or build from source. We get it.

    # Option B: Direct binary download (use the link for your architecture)
    curl -L https://downloads.qpoint.io/qpoint/qtap-latest-linux-amd64.tgz -o qtap.tgz
    # curl -L https://downloads.qpoint.io/qpoint/qtap-latest-linux-arm64.tgz -o qtap.tgz
    tar -xzf qtap.tgz
    sudo ./qtap --enable-dev-tools
Then open http://localhost:10001

    # For remote servers, use SSH port forwarding or Tailscale/Twingate
    ssh -L 10001:localhost:10001 user@remote-server
Key features: - Process/container attribution (which container made that call?) - Real-time SSE streaming - Copy any request as cURL - Data never leaves your machine

DevTools is free and open source (AGPL-3.0).

GitHub: https://github.com/qpoint-io/qtap Docs: https://docs.qpoint.io/release-notes/devtools

Questions we'd love feedback on: - What debugging scenarios would you use this for? - Any protocols beyond HTTP you'd want? (Postgres, MySQL, Redis coming soon)
