Show HN: Chaos Monkey but for Audio Video Testing (WebRTC and UDP) https://ift.tt/BI16aA4

Show HN: Chaos Monkey but for Audio Video Testing (WebRTC and UDP) It takes an input video and converts it into H.264/Opus RTP streams that you can blast at your video call systems (WebRTC, SFUs, etc.). It also injects network chaos like packet loss, jitter, and bitrate throttling to see how things break It scales from 1 to n participants, depending on the compute and memory of the host system Best part? It’s packaged with Nix, so it builds the same everywhere (Linux, macOS, ARM, x86). No dependency hell It supports both UDP (with a relay chain for Kubernetes) and WebRTC (with containerized TURN servers). Chaos spikes can be distributed evenly, randomly, or front/back-loaded for different test scenarios. To change this, just edit the values in a single config file https://ift.tt/uCALcVG February 23, 2026 at 02:23PM

Show HN: AgentDbg - local-first debugger for AI agents (timeline, loops, etc.) https://ift.tt/lmFHUtZ

Show HN: AgentDbg - local-first debugger for AI agents (timeline, loops, etc.) AgentDbg is a local-first debugger for AI agents. It records structured runs (LLM calls, tool calls, state, errors) to JSONL and shows the timeline UI locally. There is no need for cloud, accounts, and no telemetry. Flow is as simple as: 1. Run an agent 2. `agentdbg view` 3. Inspect the timeline, loop warnings, errors, etc. v0.1 includes `@trace` and `traced_run`, recorders, loop detection, best-effort redaction (by default), local UI, export. I also started working on integrations: there is an optional LangChain/LangGraph callback. * Repo: https://ift.tt/LP52D6Y * Demo: `python examples/demo/pure_python` and then `agentdbg view` Would love feedback on: 1. Trace format 2. Integrations to prioritize in the next several days 3. What you would want for deterministic replay https://ift.tt/LP52D6Y February 23, 2026 at 11:14PM

Show HN: MuJoCo React MuJoCo physics simulation in the browser using React. This is made possible by DeepMind's mujoco-wasm (mujoco-js), which compiles MuJoCo to WebAssembly. We wrap it with React Three Fiber so you can load any MuJoCo model, step physics, and write controllers as React components, all running client-side in the browser https://ift.tt/WNksA4o February 22, 2026 at 11:59PM

Show HN: DevBind – I made a Rust tool for zero-config local HTTPS and DNS https://ift.tt/Jls3nm0

Show HN: DevBind – I made a Rust tool for zero-config local HTTPS and DNS Hey HN, I got tired of messing with /etc/hosts and browser SSL warnings every time I started a new project. So I wrote DevBind. It's a small reverse proxy in Rust. It basically does two things: 1. Runs a tiny DNS server so anything.test just works instantly (no more manual hosts file edits). 2. Sits on port 443 and auto-signs SSL certs on the fly so you get the nice green lock in Chrome/Firefox. It's been built mostly for Linux (it hooks into systemd-resolved), but I've added some experimental bits for Mac/Win too. Still a work in progress, but I've been using it for my own dev work and it's saved me a ton of time. Would love to know if it breaks for you or if there's a better way to handle the networking bits! https://ift.tt/JsdVhUL February 22, 2026 at 01:49AM

Show HN: Museum of Handwritten Code (If, While, Binary Search, Merge Sort) https://ift.tt/4sDyK2x

Show HN: Museum of Handwritten Code (If, While, Binary Search, Merge Sort) Hi HN - this is a small experiment: what if code had a museum? I built a Museum of Handwritten Code for foundational constructs and algorithms. I’ve been feeling a strange melancholy watching more and more software generation become automated, and wanted to preserve the "atoms" of programming in a form people can browse, discuss, and (hopefully) learn from. Yes, it’s a vanity project — but I’m trying to make each exhibit real: code, description, and historical context (with more being added over time). If AI increasingly writes the software stack (and maybe one day much closer to machine code), then here’s to the for-loops, if-branches, and hash maps that helped build the world we live in. Cheers! I’d love brutal feedback on whether this feels: * interesting * useful * too gimmicky * or actually a decent teaching / history format https://museum.codes February 22, 2026 at 02:00AM

Show HN: Astroworld – A universal N-body gravity engine in Python https://ift.tt/FctZTqp

Show HN: Astroworld – A universal N-body gravity engine in Python I’ve been working on a modular N-body simulator in Python called Astroworld. It started as a Solar System visualizer, but I recently refactored it into a general-purpose engine that decouples physical laws from planetary data.Technical Highlights:Symplectic Integration: Uses a Velocity Verlet integrator to maintain long-term energy conservation ($\Delta E/E \approx 10^{-8}$ in stable systems).Agnostic Architecture: It can ingest any system via orbital elements (Keplerian) or state vectors. I've used it to validate the stability of ultra-compact systems like TRAPPIST-1 and long-period perturbations like the Planet 9 hypothesis.Validation: Includes 90+ physical tests, including Mercury’s relativistic precession using Schwarzschild metric corrections.The Planet 9 Experiment:I ran a 10k-year simulation to track the differential signal in the argument of perihelion ($\omega$) for TNOs like Sedna. The result ($\approx 0.002^{\circ}$) was a great sanity check for the engine’s precision, as this effect is secular and requires millions of years to fully manifest.The Stack:NumPy for vectorization, Matplotlib for 2D analysis, and Plotly for interactive 3D trajectories.I'm currently working on a real-time 3D rendering layer. I’d love to get feedback on the integrator’s stability for high-eccentricity orbits or suggestions on implementing more complex gravitational potentials. https://ift.tt/Ee0cjKS February 20, 2026 at 01:27AM

Show HN: Wakapadi – Meet locals and travelers nearby and join free walking tours https://ift.tt/BnUX1pl

Show HN: Wakapadi – Meet locals and travelers nearby and join free walking tours Hi HN, I built Wakapadi after noticing that most travel tools focus on planning trips, but not on actually helping people connect once they arrive somewhere new. When traveling, it’s often hard to meet locals or other travelers unless you already know someone, join organized tours, or rely on chance. I wanted to make discovery more natural — seeing who’s nearby, joining free walking tours, and exploring cities together. Wakapadi currently allows users to: discover free walking tours see nearby travelers and locals who are open to meeting connect and chat before meeting explore cities in a more social way The project is still early, and I’m especially interested in feedback on: safety and privacy expectations what would make you comfortable meeting people while traveling features that would make this genuinely useful instead of another travel app Happy to answer any technical or product questions. https://ift.tt/vML98P7 February 18, 2026 at 11:40PM
