GitHub - PyO3/pyo3: Rust bindings for the Python interpreter

My journey into learning Rust led me down an interesting path: the desire to gain deeper insights into my laptop’s battery. Existing options typically provide a limited view, and I was seeking a more comprehensive solution accessible through Python. This led to the creation of batteryinfo, a cross-platform Python package built upon the excellent Rust battery crate. This module empowers Python developers to go beyond simple battery percentages and access a wealth of information, including status, capacity, temperature, and even more granular details. Let’s explore how batteryinfo can provide you with a richer understanding of your laptop’s power source.

Apache OpenDAL is a data access layer provided in the form of a software library. This post discusses the history of OpenDAL, its graduation process, and the challenges faced during the graduation process.

Add a C API to configure the Python initialization without relying on C structures and the ability to make ABI-compatible changes in the future.

This informational PEP describes our shared view of the public C API. The document defines:

Building a fast boolean expression evaluation engine.

It's not a super-frequent need for me, but sometimes I'd like to be able to accept markdown from users and include the rendered output on my site. This is risky, because markdown can include arbitrary html, and libraries that process it may not focus on making sure it's safe to include in a site. For a while, bleach was the common recommendation, but it's deprecated. Since then, the ammonia library, which is written in rust, has emerged as a good functional equivalent of bleach, with a very similar interface.

Short research about making decision to use rust in medium web development shop.

With the core language library now written, I could go about building the desired (delivery) runtimes. In this post within the series, I will delve into my experience integrating the core language library with these chosen runtimes, documenting some of the challenges that I faced along the way.

Welcome back! Short and unscripted, we’re talking OpenTF and Generative AI!

Sometimes we need to extend existing Python projects with other languages to solve performance issues or to include some functionality already written in another language. In this chapter, we will create a full-featured Python integration for a Rust crate we built in the previous article. As the primary goal, I want to focus on a pleasant end-user experience and share tips on improving the usability and debuggability of the resulting library.

Py03 lets you combine Rust's speed and memory safety with Python's ease of use. Here's how to write Rust extensions for Python that work just like regular Python modules.

As part of my PhD I do computational modeling of quantum-biological systems. One of my simulations was misbehaving and in certain cases could take 8 hours to complete. That's really bad when you're trying to iterate quickly. This post describes how I made a series of optimizations to reduce the runtime by 250x via profiler driven algorithmic improvements, rewriting the core in Rust, and making use of parallelism.

My data engineering team at Fossil recently released some of Rust-based components of our Data Platform after faced performance and maintenance challenges of the old Python codebase. I would like to share the insights and lessons learned during the process of migrating Fossil's Data Platform from Python to Rust.
