New top story on Hacker News: ForeverVM: Run AI-generated code in stateful sandboxes that run forever
ForeverVM: Run AI-generated code in stateful sandboxes that run forever
28 by paulgb | 5 comments on Hacker News.
Hey HN! We started Jamsocket a few years ago as a way to run ephemeral servers that last for as long as a WebSocket connection. We sandboxed those servers, so with the rise of LLMs we started to see people use them for arbitrary code execution. While this works, it was clunkier than what we would have wanted in a first-principles code execution product. We built ForeverVM from scratch to be that product. In particular, it felt clunky for app developers to have to think about sandboxes starting and stopping, so the core tenet of ForeverVM is using memory snapshotting to create the abstraction of a Python REPL that lives forever. When you go on our site, you are given a live Python repl, try it out!

New top story on Hacker News: Show HN: Tach – Visualize and untangle your Python codebase
Show HN: Tach – Visualize and untangle your Python codebase

Hey everyone! We're Evan and Caelean, the authors of Tach. Tach gives you the tools to build a modular monolith in Python: visibility into the state of your dependencies, as well as the tools to fix them. Since our last Show HN ( https://ift.tt/GDzyJ49 ) we've shipped support for layers, third party dependencies, visualizations, and more. Tach is: * Open source (MIT) and completely free * Fast (written in Rust ) * In use by teams at NVIDIA, PostHog, and more As your team and codebase grows, code gets tangled up. This hurts developer velocity, and increases cognitive load for engineers. One way Tach differs from existing systems that handle this problem (build systems, import linters, etc) is in it's ability to be incrementally adopted and its runtime speed. If you struggle with dependencies, onboarding new engineers, or a massive codebase, Tach is for you! We built it with developers in mind - with clean integrations into Git, CI/CD, and IDEs, and the performance for it to be effective in any form factor.
