I'm switching to Python and actually liking it

news.ycombinator.com César Soto Valero 2025-07-22 18:44:32

I started to code more in Python around 6 months ago. Why? Because of AI, obviously. It’s clear (to me) that big money opportunities are all over AI these days. And guess what’s the de facto programming language for AI? Yep, that sneaky one. I had used Python before, but only for small scripts. For example, this script scrapes metadata from all videos on my YouTube channel. The metadata is dumped as a JSON file that I use to nicely display statistics of the videos on this static page.

Lua beats MicroPython for serious embedded devs

news.ycombinator.com Wilfred Nilsen 2025-07-28 13:16:02

Why Lua Beats MicroPython for Serious Embedded Devs In professional embedded projects, ranging from industrial automation to medical devices and commercial IoT products, developers increasingly favor high-level, lightweight, and easy-to-use environments. While MicroPython has earned praise for rapid prototyping and field deployments on microcontrollers, its active ecosystem is largely centered around hobbyist boards. It is important to note that Python’s greatest strength, its vast library eco

Scientists Discover Secret Weapon That Allows Pythons to Digest Bones

gizmodo.com Ellyn Lapointe 2025-08-04 18:00:40

Pythons are notorious for their eating habits. After suffocating their prey with their lithe bodies, these large snakes swallow the animal whole. Now, researchers have shed new light on the cellular mechanisms that allow them to digest entire skeletons. The study, presented July 9 at the Society for Experimental Biology Annual Conference in Belgium and published in the Journal of Experimental Biology, investigated the intestinal cells of Burmese pythons. Adult males can grow to be 10 to 16 feet

Reflections on 2 years of CPython's JIT Compiler

Reflections on 2 years of CPython’s JIT Compiler: The good, the bad, the ugly 5 July 2025 This blog post includes my honest opinions on the CPython JIT. What I think we did well, what I think we could have done better. I’ll also do some brief qualititative analysis. I’ve been working on CPython’s JIT compiler since before the very start. I don’t know how long that is at this point … 2.5, maybe almost 3 years? Anyways, I’m primarily responsible for Python’s JIT compiler’s optimizer. Note that

Show HN: A Python Language Server, Mypy-compatible

In 2012, I created Jedi—a Python auto-completion library that eventually reached millions of users and billions of downloads. But as the ecosystem evolved, one limitation became clear: speed. Jedi’s architecture couldn’t deliver the performance needed for large-scale projects. In 2020, I started over—with everything I’d learned—building ZubanLS from the ground up in Rust. After five years of full-time work, ZubanLS is now the first truly fast Python language server. ZubanLS is built for profes

Fun with uv and PEP 723

Fun with uv and PEP 723 June 24, 2025 For the longest time, I have been frustrated with Python because I couldn’t use it for one-off scripts. I had to first ensure it was running in an environment where it could find the right Python version and the dependencies installed. That is now a thing of the past. If you are not a Pythonista (or one possibly living under a rock), uv is an extremely fast Python package and project manager, written in Rust. uv also provides this nifty tool called uvx (k

Python can run Mojo now

Chris Lattner mentioned that Python can actually call Mojo code now. I love this idea (!) as I'm definitely in the market for a simple compiled language that can offer Python some really fast functions. So I gave it a quick spin Setup The setup is much simpler than I remember it, you can use uv for it now. uv pip install modular --index-url https://dl.modular.com/public/nightly/python/simple/ After that you can declare a .mojo file that looks like this: # mojo_module.mojo from python import
