Show HN: We polled 2,122 Americans on AI and regulation, and built a visualizer

Hacker News - Mon, 06/15/2026 - 12:05pm

We are researchers from Johns Hopkins University who wanted to measure American attitudes toward specific AI regulations. So we ran a poll, with SurveyUSA as our partner, to collect the data from a nationally representative sample, and we built a data-explorer to share it. We included questions about where people trust or do not trust AI, and how they expect AI to alter power, inequality, and the meaningfulness of work. There is also a quiz to try, if (a) you want to locate your own AI attitudes relative to the population, or (b) if you're just one of those people who love taking quizzes.

The data explorer on the site lets you break down the results by age, political identity, and other demographics. And the data and the questionnaire are downloadable, so you can break down the results any way you prefer. Happy to say more about the methods and motivation.

Show HN: Machine0 – Persistent NixOS VMs You Control from the CLI

Hacker News - Mon, 06/15/2026 - 12:01pm

Hi HN! Excited to launch machine0, a CLI that makes it easy to create, provision and snapshot persistent NixOS (& Ubuntu) VMs.

You can think of machine0 as a modern VPS provider. VMs stay on unless switched-off (with 99.99% uptime), they have static IPs and HTTPS endpoints, 1-60 vCPU, up to 240GB RAM and optionally GPUs. The CLI provides commands to manage lifecycle, snapshots and also provision the VMs using Nix flakes or Ansible playbooks. VMs are priced by the minute of usage.

What makes machine0 unique is that it has first class support for NixOS! In a nutshell, NixOS lets you define your entire OS as code (think Terraform but for your Linux). A flake declares your system state (packages, services, firewall rules, users...) and pins all dependencies via a lockfile. Given the same flake.nix and flake.lock, `nixos-rebuild switch` always produces the exact same system.

The NixOS ecosystem is mature, and flakes are expressive: at the system level you can define packages, what's in /etc, firewall rules, users & groups etc. At the user level, you can define your shell, aliases, tmux and vim config. Having your entire environment defined as code makes it easy to audit what's installed and how things are set up. You can rollback by reverting the last commit. And agents can write the code for you and test it against disposable machine0 VMs.

If you'd like to dive right in, these commands will get you started:

npm install -g @machine0/cli machine0 new my-vm --image nixos-25-11 # create a new nixos VM machine0 provision my-vm ./flake#my-profile # provision it using a nix flake machine0 ssh my-vm # ssh in machine0 stop my-vm # stop the VM machine0 images new my-vm my-snapshot # create a snapshot machine0 new my-clone --image my-snapshot # create a new VM from the snapshot - Demo of installation + NixOS provisioning via Claude Code: https://www.youtube.com/watch?v=RT8N0_e3Vfg

If you're in the habit of using VMs, or want to know what the NixOS fuss is about, would love for you to give machine0 a try!
