Show HN: ManimGX – Manim's API on a Rust/wgpu engine, for 3D videos in Python
3 by sinaatalay | 0 comments on Hacker News.
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*

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.

I am so tired of startups doing worse than me

I literally saw a multi million funded startup build an AI model for Android devices and tout it as their best achievement. I put a 32M parameter looped model on ESP32, an 8MB chip. I have three different softwares in production right now. I just don't understand what I am doing wrong. How are these guys getting so much money?

When you get access to a new server via ssh, what's the first command you run? ls? nproc? lsb_release -a? uname -a?

New Show Hacker News story: Show HN: Proton Drive for Linux
Show HN: Proton Drive for Linux
15 by khaosdoctor | 3 comments on Hacker News.
Hello everyone, I wanted to share this small project that I have. It's born out of a necessity that I had, because Proton doesn't ship a Linux version of the drive yet (it's apparently coming out later this year but who knows?) and all the current solutions are hacky and wonky at best. But for the time being I really needed to mount my Proton drive on my Linux machine the way I mounted it on my Mac, so I (and my faithful AI slave) did this small utility that allows you to mount your Proton Drive in a FUSE FS like if it is a local folder. It's fully written in Go because Proton's drive SDK and API libs are all in Go, and there's a community project on top of the reverse engineered proton API there too. I am not a Go developer, I know the foundations, so of course I used AI quite a lot, I am not super proud of it, but I am using it daily and testing it myself for a few months before releasing here. Hope you like it, feedbacks are welcome, just please be mindful of the person on the other side :)

I have been playing with a lot of $20 devices with no keyboards or screens. I wanted to use speech to interact with them, but without it having to run through a cloud service or use a fixed command vocabulary. I worked with Claude to implement high performance 4bit int kernels for the ESP32S3 and P4 and quantize some larger STT and TTS models. Surprisingly, it's quite usable on these tiny boards. Also includes a finetuned model that can better cope with my diesel drones, hacking coughs, and mumbling. Works with Micropython (RAM scarcity issues) and AtomVM (better).
