I was inspired to make a web based ants simulator after watching this video https://www.youtube.com/watch?v=81GQNPJip2Y Any feedback appreciated. Best viewed on Chromium based browsers. Firefox is slow for some reason and Safari is not tested as I don't have a Mac.

Hi all, I'm sure some of the best engineers out here are having a hard time standing out nowadays. It's hard to evaluate and improve your skills, when AI is writing the code. Especially when a junior dev is sitting by your side and "accomplishing" 2x more than you. I didn't like this reality where the line between real talent and AI slop is blurring, so I decided to create a challenge, purely for the community, that is made to truly give a stage for talented devs to stand out in the age of AI. We encourage devs to bring their agents with them, because the challenge is built to not be…

Hi HN, After 15 years in product management, I realized there’s nowhere for Product Managers to actually practice, most learning focuses on theory, not doing. I built The Product Sandbox, a platform where PMs can practice real-world product scenarios, make decisions, and strengthen core skills through daily missions and challenges. It’s designed for aspiring to senior PMs who want to keep improving through real practice. I’d love feedback from this community on how you think PMs (or teams) can best build real-world experience outside of their day jobs. https://sandbox4pm.com

I am a solo developer, and I built Core MBA because I was frustrated with the "video course" default in business education. I wanted to build a "compiler for business logic"—a tool where I could read a concept in 5 minutes and immediately test it in a hostile environment to see if my strategy actually compiles or throws a runtime error. The project is a business simulator built on React 19 and TypeScript. The core technical innovation isn't just using AI; it's the architecture of a closed loop between a deterministic economic engine and a generative AI validation layer. The biggest technical…

I didn't realize Universe Sandbox ran on MacOS, and I was in the mood to play around a bit. Some functions it's got: - Random system generation - Sonification is super fun too - Habitability Simulation (Just for fun, don't cite this please) - Replacing, spawning, deleting objects I've had tons of fun building this, so I hope someone else can share the joy. It's free and runs in the browser. I'd love to hear any feedback. I think this is at a state where I might leave it as it is, but if people are interested in other features, maybe I'll keep working on it. I've kept saying I'll stop working…

Train your agents before deployment and keep training them after. Generate scenarios from code, prompts, and production traces; run them in simulation; turn every verified failure into a fix or an RL reward.

Kshitij and Rahul here. We're building Playground, an open-source sandbox that lets your non-technical teams prototype directly on production codebases, without bugging you (developers) to spin up and maintain another repo. The repo is here: https://github.com/B1u3B01t/design-playground. We've been working together for six years. Last year we built an AI design agent because we thought designers were the biggest bottleneck. But we were wrong. After talking to teams, we realised designers, PMs, founders and even sales people all wanted to quickly change and explore flows…
