    Single file C simulation. Cells on a grid eat soil, fight neighbours, reproduce with mutations. No neural network. No backpropagation. No fitness function. No pathfinding. Evolutio…

    Prompt injection is the same problem all agents face, ChatGpt Atlas, claude cowork, openclaw, all of them. It's a known unsolved problem across the industry. I mitigate it by givin…

    Interesting. Part of why I built this was to avoid screen capture as the control layer. Once you’re taking screenshots, guessing what to click, moving the mouse, and repeating, it …

    Yeah, instruction drift is a real problem in long agent chains. In this case the workflow gets decomposed into steps up front and each step is executed by a separate sub-agent. So …

    linux and windows support is on the way, i’ve designed it in a decoupled way, so should be straight forward. Just need to see if people find this version useful

    Show HN: AI agent that runs real browser workflows

    I’ve been experimenting with letting an AI agent execute full workflows in a browser. In this demo I gave it my CV and asked it to find matching jobs. It scans my inbox, opens the …

    I audited 3 vibe coded products that were posted on Reddit in a single afternoon. All three had critical security vulnerabilities. One was a live marketplace with real Stripe payme…

    This isn't another 'AI bubble bad' post. The article traces a specific financial contagion pathway that hasn't been covered elsewhere in a single piece. Tech companies are moving h…

    Show HN: A deterministic code-rewrite engine that learns from one example

    I built a tool that learns structural code transformations from a single before/after example. It isn’t a transformer or LLM — it doesn’t generate code. It extracts the structural …

    I built an AI that learns code transformations from examples (not generative)

    I built a tool that learns structural code transformations from before/after examples. Show it console.log(x) -> logger.info(x) and it learns the pattern, then applies it across yo…

    This still seems like gradient descent wrapped in new terminology. If all learning happens through weight updates, its just rearranging where the forgetting happens

    The idea is interesting, but I still don’t understand how this is supposed to solve continual learning in practice. You’ve got a frozen transformer and a second module still traine…

    Do you have a source for the NVIDIA “diffusion plus autoregression 6x faster” claim? I can’t find anything credible on that.

    This started as a small experiment in structural rewriting. The basic idea is that you give the system two or three before and after examples, press Teach, and it learns that trans…

    If anyone saw odd behaviour just now in the demo, that was my fault. One of the codemod rules was leaking into the shared rule registry instead of being scoped to the current user.…

    Right, associativity is the simplest case because the structure is visible directly in one example. The system needs multiple examples when there is more than one varying part and …
