Learning Nix with LabCraft

What it does

Build real systems judgment on isolated machines that are yours to break. Hands-on courses in Nix, NixOS, and the infrastructure layer — where the mistake is the lesson.

LabCraft gives engineers real Linux environments, broken states to diagnose, and validation against outcomes instead of keystrokes. The course content is executable and tested like code, so labs keep working as the tools change. Most courses hand you the happy path and call it teaching. We don't dodge the wrong turns: when a mistake teaches more than a clean run, the chapter gives you a real system, a recoverable failure, and the evidence needed to understand what happened. Every command runs on real machines provisioned just for you. A lesson spins up as many as it needs, from one box to several wired into a network, and they're yours to configure, break, and rebuild. Where a wrong turn…from labcraft.dev

In the maker’s words, at launch

LabCraft is an AI-mentored learning platform. It is NOT a chatbot! Instead, it consists of course curriculum and an instrumented playground where learners can safely practice what they learn. The AI mentor observes the user's actions in the playground, and guides them towards the objective when they are stuck. This…

  AI Playground by Vercel Labs2023 · play.vercel.ai · ▲249

  Hey, Jared Palmer (creator of this playground) here. Really excited to ship this. I’ve been building this over the past few weeks to compare LLMs from different providers like OpenAI, Anthropic, Cohere, etc. At Vercel, I manage our Frameworks division (including Next.js, Svelte, and Turbo) and wanted to also dogfood some of the latest features in a slightly larger application. This playground takes a lot of inspiration from https://nat.dev and is built on Tailwind, ui.shadcn.com, and some upcoming Vercel products we’re announcing soon. We’re going to continue adding models to…

  We build AI agents to find vulnerabilities in other AI agents. The playground started as an internal tool that we used to test our own offensive agent Nyx. But we realised that hacking an AI is about have as wide a distribution of attacks as possible, especially those which aren't in the distribution of the models. So we are launching playground as a platform to crowdsource agent jailbreaks. And although hacking AI is super fun and we are sure people will do it for free, we want to reward those who help us push forward the offensive frontier of AI. So we are committing $100K in prizes over…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
