Show HN: Subtrace – Wireshark for Docker Containers https://ift.tt/tiCh7eQ

Show HN: Subtrace – Wireshark for Docker Containers Hey HN, we built Subtrace ( https://subtrace.dev ) to let you see all incoming and outgoing requests in your backend server—like Wireshark, but for Docker containers. It comes with a Chrome DevTools-like interface. Check out this video: https://www.youtube.com/watch?v=OsGa6ZwVxdA , and see our docs for examples: https://ift.tt/AHa7UzR . Subtrace lets you see every request with full payload, headers, status code, and latency details. Tools like Sentry and OpenTelemetry often leave out these crucial details, making prod debugging slow and annoying. Most of the time, all I want to see are the headers and JSON payload of real backend requests, but it's impossible to do that in today's tools without excessive logging, which just makes everything slower and more annoying. Subtrace shows you every backend request flowing through your system. You can use simple filters to search for the requests you care about and inspect their details. Internally, Subtrace intercepts all network-related Linux syscalls using Seccomp BPF so that it can act as a proxy for all incoming and outgoing TCP connections. It then parses HTTP requests out of the proxied TCP stream and sends them to the browser over WebSocket. The Chrome DevTools Network tab is already ubiquitous for viewing HTTP requests in the frontend, so we repurposed it to work in the browser like any other app (we were surprised that it's just a bunch of TypeScript). Setup is just one command for any Linux program written in any language. You can use Subtrace by adding a `subtrace run` prefix to your backend server startup command. No signup required.

Show HN: A GPU-accelerated binary vector index https://ift.tt/1eKhHJM

Show HN: A GPU-accelerated binary vector index This is a vector index I built that supports insertion and k-nearest neighbors (k-NN) querying, optimized for GPUs. It operates entirely in CUDA and can process queries on half a billion vectors in under 200 milliseconds. The codebase is structured as a standalone library with an HTTP API for remote access. It’s intended for high-performance search tasks—think similarity search, AI model retrieval, or reinforcement learning replay buffers. The codebase is located at https://ift.tt/OrD5IbR . https://ift.tt/s5bpAZV February 17, 2025 at 06:15AM

Show HN: Automate Expo QR Code Previews in GitHub PRs https://ift.tt/Ezs9TIu

Show HN: Automate Expo QR Code Previews in GitHub PRs Hey HN, Inspired by Vercel’s automated preview deployments, I built a GitHub Actions workflow that generates an Expo QR code per PR—so mobile previews are as easy as scanning a QR code. How it works: • Every PR triggers a GitHub Action • The action starts an Expo server • It posts a QR code in the PR comments for instant testing on mobile No more manually starting Expo. No more copying links. Just open a PR and scan the code. Full guide here: https://ift.tt/jF1ZlQM Would love to get feedback—how would you improve this workflow? https://ift.tt/jF1ZlQM February 17, 2025 at 10:03PM

Show HN: Hackyournews.com v2 https://ift.tt/oHhIwvF

Show HN: Hackyournews.com v2 A year and a half after I published https://ift.tt/7tSDiYc , I've rewritten it to be neater and added support for more news sources. HackYourNews.com v1 had a great response on HN [1] and consistently sees ~2k weekly unique visitors. There were many long-standing requests that I wanted to fulfill (thanks for your patience!): a proper dark mode, correct rendering on mobile devices, and more cogent summaries. This rewrite is the result. gpt-4o-mini reduces the cost of summarization to an absurd degree, so it's now sustainable to keep this free service going! Someday, I hope to use the Batch API [2] to drive down costs even further. Enjoy. [1] https://ift.tt/GmcSjfV [2] https://ift.tt/lJ6LGxj February 16, 2025 at 06:16AM

Show HN: I got frustrated with CRMs, so I'm building my own for startups After trying a bunch of CRMs for my startup, I kept running into the same issues—overpriced plans that scale aggressively or bloated features that just slow me down. I wanted something simple, affordable, and actually built for startups, so I decided to build it myself: Leadchee.com. Fixed pricing, no nonsense. Curious—how do you all handle CRMs? Do you stick with the big players, go for niche tools, or build your own? Would love to hear your thoughts! https://leadchee.com February 14, 2025 at 09:25PM

Show HN: Open-Sourcing My LLM Drag and Drop Website Builder https://ift.tt/Q0StYNc

Show HN: Open-Sourcing My LLM Drag and Drop Website Builder Hey HN - OP here. I wrote some about this project in the following link, and there's a video demo as well: https://ift.tt/456gJcz... This has been one of my favorite things I've ever worked on - the way the LLM collaborates with the user to accelerate tedious and hard work, the way you can directly edit the code instead of dealing with a panel of visual editing toggles - I think it has a lot of potential but I don't have time to pursue it anymore so open-sourcing it. The idea for this came out of conversations with a few people who were struggling with frontend development. For technical people, strictly using an LLM to write code can be tedious. To combat this, LLM usage is limited to getting started quickly, improving design, and wiring up frontend state. On the other hand, writing frontend code feels less efficient than just moving things around on a screen. Hence the drag and drop interface that makes it fast to build. Finally, I despise the visual editing toggles on Figma / Bubble / Squarespace / etc. The amount of hunt and peck to simply adjust a font a bit and change some colors or add a shadow is a huge time suck. So I built a way to directly edit the underlying React code when styling - just add or remove tailwind classes. IMO the craziest thing is that all of the code is just stored on the frontend in a config language of sorts. It is inflated at runtime and can be updated without any hot reload. There is no "underlying React code" for the app you're building here - in order to edit the code, I convert the config into React code, then convert back to a config, which triggers updates in the dom. Anyways, I think there's a lot of clever stuff in here, but then again I wrote it. Happy to answer any questions and hope this is interesting/helpful to someone else out there. https://ift.tt/XcqeQit February 14, 2025 at 11:38PM
