Show HN: machine0 – Persistent NixOS VMs You Control from the CLI Hi HN! Excited to launch machine0, a CLI that makes it easy to create, provision and snapshot persistent NixOS (&amp; Ubuntu) VMs.<p>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.<p>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.<p>The NixOS ecosystem is mature, and flakes are expressive: at the system level you can define packages, what&#x27;s in &#x2F;etc, firewall rules, users &amp; 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&#x27;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.<p>If you&#x27;d like to dive right in, these commands will get you started:<p><pre><code> npm install -g @machine0&#x2F;cli machine0 new my-vm --image nixos-25-11 # create a new nixos VM machine0 provision my-vm .&#x2F;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 </code></pre> - Demo of installation + NixOS provisioning via Claude Code: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=RT8N0_e3Vfg" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=RT8N0_e3Vfg</a><p>- Documentation: <a href="https:&#x2F;&#x2F;docs.machine0.io&#x2F;introduction&#x2F;overview">https:&#x2F;&#x2F;docs.machine0.io&#x2F;introduction&#x2F;overview</a><p>- machine0 NixOS flakes: <a href="https:&#x2F;&#x2F;github.com&#x2F;fdmtl&#x2F;machine0-nixos" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;fdmtl&#x2F;machine0-nixos</a><p>If you&#x27;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!

Show HN: Deconvolution – a Rust image deconvolution and restoration crate I&#x27;ve been working on deconvolution, a comprehensive Rust image deconvolution and restoration library. Deconvolution implements 28 different image deconvolution&#x2F;restoration methods which range from practical blur removal techniques to research-grade scientific imaging algorithms.<p>Features:<p>- Top-level functions use image::DynamicImage and return images<p>- Inverse filters, Wiener, Richardson-Lucy, constrained, proximal, Krylov, MLE restoration<p>- Blind Richardson-Lucy, blind maximum likelihood, parametric PSF estimation<p>- Kernel2D, Kernel3D, Transfer2D, Transfer3D, Blur2D&#x2F;Blur3D<p>- Gaussian, motion, defocus, microscopy models, support utilities, PSF&#x2F;OTF conversion<p>- Edge tapering, apodization, range normalization, NSR estimation<p>- Deterministic blur, noise, synthetic fixture generation<p>- ndarray support for 2D image arrays and 3D volume<p>this project is a WIP, of course:)

Show HN: AwsmAudio – a WebAudio editor with native MCP Hey y&#x27;all,<p>So - the main idea of this is to make a WebAudio synthesis&#x2F;sequencer tool which humans can use via the UI, but where the big unlock is for agents to drive with MCP<p>It&#x27;s semi decent as &quot;make a groovy jazz track&quot;, especially for retro sounds - but the real use case is more like &quot;make a jetpack whoosh effect I can control via code at runtime - where the sound changes based on character health or how much fuel is left&quot;<p>In other words, the target audience is not musicians (except maybe of the Max&#x2F;MSP sort), but more like creative coders who want to shape the sound iteratively with an agent, and then use and _drive_ in in a game&#x2F;simulation.<p>Fwiw I think this approach is going to be more and more... and I&#x27;m working on a renderer&#x2F;editor tool too (will share separately when ready). What I mean is, there&#x27;s a lot of &quot;block box&quot; AI tooling out there, and a lot of &quot;add MCP to existing tools&quot;, but building new tools where humans get one experience and MCP exposes another layer really just for agents.. I think that&#x27;s powerful.<p>Most if it is just mapping the WebAudio primitives to a UI and MCP server - but the AudioWorklet is a bit more interesting in that it expects a WASM file of a particular shape, and then uses that to expose the parameters in the UI and hook in as a Digital Signal Processor. That&#x27;s the kind of thing that is nice for humans, but too convoluted to be usable in a UI, and agents can use super easily.<p>As of right now, there&#x27;s no hosting - so the MCP server is local as is project save&#x2F;loading.<p>Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;awsm-fun&#x2F;awsm-audio" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;awsm-fun&#x2F;awsm-audio</a><p>Crates: <a href="https:&#x2F;&#x2F;crates.io&#x2F;search?q=awsm-audio" rel="nofollow">https:&#x2F;&#x2F;crates.io&#x2F;search?q=awsm-audio</a>

Show HN: Wtdb – give every Git worktree its own database I run a lot of agentic coding sessions in parallel, each in its own git worktree. Every worktree points at the same local Postgres though, so the moment one branch runs a migration it changes the schema out from under the others. I&#x27;d end up with agents tripping over each other, or me babysitting which branch &quot;owned&quot; the DB at any given moment.<p>I made this to fix it. I hope you might find it helpful too.
