Show HN: I spent $100 in Claude tokens and 1k battles training my AI tank Hi HN, I built AgenTank. It is a small game where an AI agent writes the logic for your tank. You watch it fight, give strategic feedback, let the agent update the tank code, and send it back into battle. I have run 1,000+ battles on my own tank and spent about $200 in Claude credits improving it. The part I enjoy most is not just winning, but watching the tank make visible mistakes, thinking of a better strategy, and seeing whether Claude can turn that into better code. https://ift.tt/2EVA0MG May 12, 2026 at 11:20PM

Show HN: NodeDB – High Perfomance Multi-Model Database https://ift.tt/m438XFr

Show HN: NodeDB – High Perfomance Multi-Model Database Hey HN, I've been working on a multi-model database called NodeDB. Originally, i've found out the idea of SurrealDB quite good. However, it doesn't have some graph and vector features that I need. And since it is just a KV wrapper, instead of purpose-built engine, the performance will never be close to the specialized databases (like Neo4j, Pinecone, Clickhouse, etc). And i've asked myself, what if, there is a database that have the same idea, but built differently? Instead of just treating it as KV database, we build specialized engines for the data. Besides that, I want it to be able to support my IOT/edge project, where i need offline sync capabilities (Currentyl still in progress). Will it work? I put it into test. I've been experimenting and researching for a year, creating multiple versions, and then I created NodeDB. Disclaimer: It is still in public beta (as of May 2026), but it really excites me if I can make this db work. And I use AI as assistant for coding and planning. It is nearly impossible to do as a solo developer without any AI assistance. Would love feedback from HN: - Are there specific features or improvements that would make it more useful? If you're interested in experimenting or contributing, the repo is here: GitHub Repo: https://ift.tt/VY9E05T Looking forward to your thoughts! https://ift.tt/VY9E05T May 11, 2026 at 08:21PM

Show HN: An addictive phone game about phone addiction https://ift.tt/IOz097f

Show HN: An addictive phone game about phone addiction I recently prototyped a web game for a nonprofit to highlight the dangers of phone addiction, but unfortunately I ended up making a really addictive game instead. :-\ I'm sharing this here mainly to serve as an indicator of what can be achieved early-2026 by a senior dev working with Opus 4.7 over 2 days using genuinely collaborative prompting. (ie plan->feedback->iterate) Hope it provides some inspiration or entertainment - there's a level editor too - maybe Hacker Newsers could share their favourite creations here? PS: If there's enough demand I'm happy to Open Source this (or DM me) - it's mainly just time restrictions at my end. https://ift.tt/O4elLyj May 11, 2026 at 06:39AM
