Show HN: Nimic – Pure Python as a systems language with AOT compilation A recent benchmark showed that a pure‑Python program compiled with Nimic ran up to 4× faster than the same code executed by CPython, rivaling small‑C utilities. If you’ve ever thought you needed to learn C, Rust, or Go to write high‑performance system tools, Nimic proves you can stay in the python ecosystem and still ship native binaries. Imagine writing a data‑processing script that pulls a massive CSV with pandas, does heavy numeric crunching with numpy, and then ships as a single executable you can run on any server—no virtualenv, no Docker, just a single file. In This Article What is Nimic and How Does It Fit Into the Python Landscape? Installing Nimic – From pip to First‑Run Practical Walkthrough: Building a High‑Performance Data‑Science CLI Why This Matters: Real‑World Impact for Python Developers Actionable Takeaways & Next Steps Frequently Asked Questions What is Nimic and How Does It Fit...

Matt's Script Archive: The Scripts That Reshaped the Web In 2009, a single line of JavaScript saved a Fortune 500 company ≈ $1.2 M in manual labor each year— and it lived in a little‑known folder called Matt’s Script Archive . If you’ve ever built a Zapier or n8n workflow, you’ve probably already been standing on the shoulders of Matt’s code, even if you didn’t know his name. In This Article 1. The Origin Story 2.
