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: Jevman – AI decision models play Pac-Man https://bit.ly/4BffG8D

Show HN: Jevman – AI decision models play Pac-Man Openai just launched their decisions endpoint, cloudflare launched clef the other week, and many more jev alternatives are out there. We wanted to put the popular ones to the test and thought Pac-Man is a good benchmark for simple and fast decision making. So we let jev 1.13, kev, clef, clef flash, GPT-6 Luna and Laya play Pac-Man against bot ghosts. The low latency of these models allows for real time play. We had each model play 100 games, published a leader board and open-sourced the repo so anyone can run their own model and join the ranking. Link to repo: https://bit.ly/4yeVMYC... You can also join the game and play as Pac-Man yourself, and the ghosts are the models, either a mix of models or all jev, kev, clef etc. A game costs about 2 cent, all models are running via my startup opper, and we added free credits for everyone to try. It's pretty fun to play and surprisingly difficult to beat jev's highscore. Any feedback is more than welcome! https://bit.ly/4zmQXx9 October 8, 2026 at 05:34PM

Show HN: Convkit – A command line tool for converting images/video/docs offline https://bit.ly/4j6jjHf

Show HN: Convkit – A command line tool for converting images/video/docs offline Going to some shady website for file conversions was really annoying me because I had to hope whatever I gave them wasn't saved, and whatever I got back wasn't something "unexpected." So I made convkit, a CLI that does file conversions 100% locally. Run conv in.mp4 out.gif and you get your GIF from the right tool (ffmpeg, ImageMagick, etc.) using settings tuned for good output. For example, a GIF's 256 colors are picked from the clip itself instead of ffmpeg's generic palette. And if you've ever had an issue uploading a file that is too large, you can use the --max-size flag: conv clip.mp4 --max-size 10mb It trades resolution, frame rate and bitrate against each other, so you get the best-looking version that still fits. Notes - In early stages (0.3.x) so some issues pop up - You only need the tools for the conversions you use, so video and GIFs only need ffmpeg; LibreOffice, pandoc and Typst are only for documents; Image to Image needs ImageMagick. - Not all features are listed. If you are interested go to the github page! https://bit.ly/4jEy5VO - If you want any specific conversions, let me know! Thanks for reading! https://bit.ly/4jEy5VO October 7, 2026 at 06:59PM

Show HN: TerrainSR – fast, realistic heightmap upscaling model https://bit.ly/4i6Jmgj

Show HN: TerrainSR – fast, realistic heightmap upscaling model This is a model that I made for a historical game. I wanted to have a 1:1 scale model of Europe, but my problem was that 100m data was too low-res while 10m LIDAR data was patchy, took hundreds of GBs to store and was full of manmade objects like mines, buildings and so on. I trained this model on undeveloped landscape so that it can quickly add plausible erosion features, rocks, etc to the low-resolution height data and sort of reconstruct what the terrain would look like before any human interference. https://bit.ly/4AREFON October 7, 2026 at 02:24AM

Show HN: An eBPF kernel guard for vTPM access https://bit.ly/4hH6UqP

Show HN: An eBPF kernel guard for vTPM access A kernel guard I prototyped after eBPF and vTPM work for a customer, where we use the TPM to protect the private keys for mTLS. Any process running as root can open the TPM devices, and so can any process in the `tss` group, through `/dev/tpmrm0`. That means they can use those keys too. This is a prototype and some research into protecting this path. https://bit.ly/4hLfDZa October 4, 2026 at 10:34PM
