Show HN: Xit – a Git-compatible VCS written in Zig The marquee feature is patch-based merging, similar to Darcs and Pijul. I think xit is the first version control system (VCS) to have this feature while still being git compatible. See the 100% human-written readme for more. https://ift.tt/6UYf27P April 15, 2026 at 01:36AM

Show HN: Helix – open-source self-healing back end for production crashes Six months ago I got tired of being woken up at 3am for bugs I already knew how to fix. So I built Helix. Bug hits Sentry. A multi-agent pipeline kicks off. QA agent writes the failing test first (TDD). Dev agent writes the minimum fix, runs the full suite, opens a PR. You get a Slack message with one button to approve. Crash to merged PR in under 10 minutes. https://88hours.github.io/helix-community/ April 14, 2026 at 11:07PM

Show HN: A Bomberman-style 1v1 game where LLMs compete in real time A few weeks ago, ARC-AGI 3 was released. For those unfamiliar, it’s a benchmark designed to study agentic intelligence through interactive environments. I'm a big fan of these kinds of benchmarks as IMO they reveal so much more about the capabilities and limits of agentic AI than static Q&A benchmarks. They are also more intuitive to understand when you are able to actually see how the model behaves in these environments. I wanted to build something in that spirit, but with an environment that pits two LLMs against each other. My criteria were: 1. Strategic & Real-time. The game had to create genuine tradeoffs between speed and quality of reasoning. Smaller models can make more moves but less strategic ones; larger models move slower but smarter. 2. Good harness. I deliberately avoided visual inputs — models are still too slow and not accurate enough with them (see: Claude playing Pokémon). Instead, a harness translates the game state into structured text, and the game engine renders the agents' responses as fluid animations. 3. Fun to watch. Because benchmarks don't need to be dry bread :) The end result is a Bomberman-style 1v1 game where two agents compete by destroying bricks and trying to bomb each other.

Show HN: The Infinite Tolkien – endless narration of Middle-earth https://ift.tt/8z4nCoJ

Show HN: The Infinite Tolkien – endless narration of Middle-earth Inspired by The Infinite Conversation ( https://ift.tt/TVqbunP ), I built a site where J.R.R. Tolkien endlessly describes the landscapes of Middle-earth — trees, hills, rivers, ruins, dawns — one scene at a time, forever. If you've read Tolkien, you know the man could spend an entire page describing a single tree. My friends and I always joked about it. When I saw the concept of an infinite AI conversation, the connection was immediate: what if Tolkien never stopped describing things? It's a satirical/art project, not a serious product. The voice cloning is decent but clearly not perfect — which honestly fits the spirit of it. Source: https://ift.tt/J3CclbZ https://ift.tt/iV2FYH4 April 13, 2026 at 02:24AM
