Show HN: Yagi, Rust DSP Library Hi HN, I'm a big fan of the liquid-dsp C library and thought it'd be fun to bring it over to Rust. I'm calling this library Yagi DSP. liquid-dsp has more than 1300 tests and yagi now has ported and passes more than 95% of them. I've just finished a major refactoring of the library with lots of API churn now behind me and I think it's now ready for external users. I've still got a lot more I'm hoping to do with it including a streaming graph/dataflow library that I'm building on top of yagi. My goal with that is to create something that's easily embeddable in applications. The browser demo linked in the README is just a very basic example to show how different modems work in the presence of noise, but it really does use yagi via wasm-bindgen. I think it's a fun 5 minute diversion if you've heard terms like QPSK or QAM but aren't sure what they mean.

Show HN: ManimGX – Manim's API on a Rust/wgpu engine, for 3D videos in Python https://ift.tt/QOiek9H

Show HN: ManimGX – Manim's API on a Rust/wgpu engine, for 3D videos in Python Video as code took off with the Opus 5.5 release. People now make videos by writing code, with Remotion, HyperFrames and others. We wanted the same for 3D videos. You can use something like Blender, but it's heavy to install and slow to render. So we made ManimGX: - Lightweight: a 65–110 MB download, depending on the OS - Easy to install: pip install manimgx (Python 3.13+), with no system dependencies - Cross-platform: macOS, Windows and Linux, and even the browser via Pyodide and WebGPU - Blazingly fast: a Rust + wgpu engine, 90.6× faster than Manim CE and 18.7× faster than Blender Workbench, from launch to finished MP4 - Compatible with Manim Community Edition's API, with LaTeX and Typst math built in Now it's much easier for anyone with a coding agent to make 3D computer graphics videos.

Show HN: Throw Alice and Bob into Sagittarius A* https://ift.tt/ajbLeQR

Show HN: Throw Alice and Bob into Sagittarius A* Black Hole Lab is an open source physics simulation of a rotating black hole and two observers, Alice and Bob. You can launch Alice and Bob on paths around or into the black hole and watch events play out. The simulation lets you see a slice of the physics with one or two dimensions of space plus one of time. As a fun extra, Alice and Bob each have a beacon that can transmit a radio wave in all directions. The simulation calculates and shows the wavefront of these signals, accounting for the warping of space and time by the black hole. The simulation also records whenever Alice and Bob receive each other's transmission. The simulation takes pains to respect Einstein's equations of general relativity. To the precision of the numerical integration, the effects shown in Black Hole Lab are really what the math of general relativity says will happen. Black Hole Lab specifically uses the Kerr metric, which is an exact solution to Einstein's equations of general relativity for a rotating mass. That said, physicists agree that general relativity cannot be the final word on black hole physics. Nobody can say what would really happen to Alice and Bob. My original goal for black hole lab was to try to understand the strange time compression effects at the inner horizon, which physicists call infinite blueshift. IMHO, Black Hole Lab succeeds in showing this effect in an understandable way. I added a specific discussion of infinite blueshift in the readme. https://ift.tt/LXyfzPB October 11, 2026 at 01:28AM
