I wanted to see how fast an isolated code sandbox could start if I never had to boot a fresh VM. So instead of launching a new microVM per execution, I boot Firecracker once with Python and numpy already loaded, then snapshot the full VM state. Every execution after that creates a new KVM VM backed by a `MAP_PRIVATE` mapping of the snapshot memory, so Linux gives me copy-on-write pages automatically. That means each sandbox starts from an already-running Python process inside a real VM, runs the code, and exits. These are real KVM VMs, not containers: separate guest kernel, separate guest…

Hi one and all. I've created an encrypted personal organizer I wish to share with you all. I know.... you are sighing and thinking "Oh! No! not another one". doogiePIM is different in that it's built by the same coder that created one of the very first PIMs that came out around 18+ years ago and creator of TexNotes way back then (it was actually called Scribillo. Wow, I feel old). The original PIM was sold then abandoned by GemX Software and that made me feel really bad. So, I obtained the full code and started to build a far better version of the information manager. One that will…

A little weekend project, made so I can pause/play/rewind directly on the piano, when learning a song by ear.

hey guys. the other day i was migrating hosting providers and i just needed something not too heavy and convenient to spin up my backups for awhile and realised there is almost nothing out there. kimchi hasn't been updated for years and cockpit is heavy. so here's something i came up with in a couple hours because of a sudden urge, nothing fancy just basic creation with cloud init, lifecycle management and image/storage, but it's modern-ish and it compiles to a 8.4mb binary inclusive of the embedded web UI, CLI and API, and only dep is libvirt.

Microterm is a fully compliant Linux virtual machine that runs in any browser tab. It is designed for real development and operations workflows, not demo-only terminal output. You can use it on desktop, tablets, and phones, including iOS home-screen PWA installs. Under the hood, Microterm combines Restty (libghostty + WebGPU) web terminal rendering and a TinyEMU-backed Alpine Linux guest on RISC-V64. The VM image is chunk-loaded in the browser and booted locally. I successfully used it to run Codex directly without leaving an in-app preview inside X app or Telegram :) Can be used to SSH to…

Hey all! I wanted to share this project I've been working on that can maybe help you or your developer friends out. I built a RAG system for our product a while back and didn't realize how easy they were to get started. So I put together my learnings into this online course. It's not quite ready but if you sign up and mention HackerNews, I can get you early access. I'm looking to get feedback on the following: (1) materials — is it engaging & did you learn something? (2) UI/UX of the platform — did you have any issues that prevented you from starting or finishing the tutorial? (3)…

SmolVM is an open-source local sandbox for AI agents on macOS and Linux. I started building it because agent workflows need more than isolated code execution. They need a reusable environment: write files in one step, come back later, snapshot state, pause/resume, and increasingly interact with browsers or full desktop environments. Right now SmolVM is a Python SDK and CLI focused on local developer experience. Current features include: - local sandbox environments - macOS and Linux support - snapshotting - pause/resume - persistent environments across turns Install: ``` curl -sSL…

I've been running Pi using SmolVM to build SmolVM! SmolVM provides an abstraction over microVMs to easily create sandboxes for coding agents, OpenClaw, or just to build a custom harness. To use it, install using: curl -sSL https://celesto.ai/install.sh | bash and then run: smolvm pi start

How puffnfresh, my coworker, made a single command to download, assemble, and boot the VM image is arguably as cool as the port itself!

I was a huge Pocket user, even before Firefox entered the picture. But it lacked some features and started to not work well offline. And for my use, I need to be able to read when I don't have internet. I started working on this over a year ago. This is my third re-write. First was in Kotlin, then Expo, then Tanstack. I've been loving building PWAs, especially local first ones. Savr has a long way to go, but I have been dogfooding it for a while and I hope to get some feedback from yall. See the code design at https://github.com/jonocodes/savr Use the app at…

Hi HN, I spent the last few months reading the RISC‑V specification to build the lightest possible sandboxes. The idea behind a vpod is to quickly spin up a Linux sandbox from snapshots (Alpine by default) without any setup or subsystem required. The trade-off for portability and security is raw CPU speed. So we don't expect it to match native workloads with Python or pip, for example. More info is in the README https://github.com/capsulerun/vpod Happy to answer any questions!
