VCN #43: Cattle, Not Pets

the vibe

Stop nursing one precious dev box. Give every agent task its own throwaway machine. A container sandbox keeps your agent from trashing your laptop. A whole disposable VM goes a level further: full-OS isolation, its own kernel, its own everything. Spin it fresh, hand it to the agent, let it run wild, then destroy the box. Nothing leaks back. Nothing accumulates. The VM is cattle, not a pet. VCN #43: Cattle, Not Pets is the builder night where you wire that up. Format: The walkthrough. Firecracker microVMs, Lima, and Multipass, what each one is for, and where a full VM beats a container sandbox. cloud-init to bootstrap the box, snapshot/restore to make spin-up instant. The pattern. One ephemeral VM per agent task. Spin fresh, drop the agent in, run, tear down. We walk the lifecycle end to end. Build your own. Hands-on hour. Write a script that spins a fresh throwaway VM, runs your agent task inside it on Nebius Token Factory credits, and tears it down after. Claude Code on z.ai drives the agent in the box. Demos + social. Show your spin-and-destroy script. Compare snapshots, boot times, and teardown. By 10pm you leave with a script that spins a fresh throwaway VM for an agent task and tears it down after. Builders only. Bring a laptop and an agent task you want to run in full isolation. Doors 7pm. Walkthrough 7:30. Frontier Tower Floor 10. Hosted by Vibe Coding Nights: Rayyan Zahid (Immersive Commons), Michalis Vasileiadis (Hacker Bob), Eric Mockler (AI Geneticist), Devinder…
