Show HN: HexBOTs – a cellular automaton with robotic lawnmowers Double-click or press N to start a new experiment. I built hexBOTs, an unusual cellular automaton based on deterministic robots. The robots behave a bit like robotic lawnmowers, moving through their environment and reacting according to their individual rules. The robots themselves are fully deterministic — no random functions are used while they are running. What makes them different is their “genetics”: each robot's behavior is defined by a randomly generated genome, which allows for an enormous number of different robot types. Randomness creates the robots, but it doesn't drive them. Once an experiment starts, everything follows deterministically from the generated genomes and the initial state. What fascinates me is the complexity that emerges from these relatively simple machines interacting with each other and their environment. Controls: B — enable/disable robots (also: hold mouse/finger down) R — restart N ...

Show HN: Fast Cut Video tool for cutting video for Agents Hi HN, Build this tool in a couple of hours with OpenAI Codex to scratch an itch. As part of my videos workflows I needed to cut the videos myself since the agent is pretty bad cutting and timing using only the transcription. But using a big app like Premiere or DaVinci Resolve was overkill so I used Astra to build an app tailored to that very task. It will be useful to others with the same problem. Tested only on Silicon Macs, so any feedback is welcome. As part of my workflow when the agent get the video it can open the app with the video or videos loaded in the timeline for me to cut and then export the cuts in a format the agent can use and continue the workflow. https://ift.tt/sACfLyT September 6, 2026 at 04:06AM

Show HN: HyperCard to HTML Converter I created a converter that turns HyperCard 2.x stacks into standalone HTML so they can run in a modern browser. I built it to share my own stacks from the early '90s, which have been sitting on old floppy images for 30 years. It's MIT-licensed and I'd welcome contributions - especially stacks that break the converter, since I've only tested it against my own. If you have old HyperCard files lying around, I'd love to hear how they fare. https://ift.tt/YQI8S5o September 5, 2026 at 11:11PM

Show HN: TERMy – A fast terminal assistant that does not use LLMs I love research and development, you may have heard of me because of PJON (Padded Jittering Operative Network). It is a network protocol I started developing in 2010, which was recently implemented in silicon by the ETH Zurich university thanks to the research of Pius Sieber. I am excited to share with you TERMy, a terminal assistant built on top of the NPC-Forge framework. Unlike everything else being built today, TERMy does not use embeddings, machine-learning or LLMs. It runs on the CPU (even on a Raspberry Pi Zero) both in the terminal or client-side in a browser tab and responds in milliseconds. It is a cynical but very knowledgeable Linux terminal assistant that translates your natural language into shell commands without relying on a single artificial neuron. I had a chance to focus for 2 months on my personal projects since early July, during the strange times of AI price hikes and the end of subsidized tokenmaxi...

Show HN: LibPolyCall – a C runtime broker for cross-language function calls LibPolyCall is an open-source C runtime for connecting programs across language boundaries without requiring each language pair to implement its own integration layer. The architecture is program-first rather than binding-first, with a stable C ABI, FFI bindings, Polycallfile/Polycallrc configuration, runtime state management, and telemetry. I’ve recently completed the Windows build path producing both libpolycall.dll and libpolycall.a, and I’m working toward using the same runtime across Python, Node.js, Java, Go, and other language environments. I’d particularly appreciate feedback on the ABI design, runtime architecture, configuration model, and approach to cross-language dynamic loading. https://ift.tt/D8lviAF September 4, 2026 at 12:05AM
