PyViz – Overview of the Python visualization landscape (pyviz.org)
The Python visualization landscape can seem daunting at first. These overviews attempt to shine light on common patterns and use cases, comparing or discussing multiple plotting libraries. Note that some of the projects discussed in the overviews are no longer maintained, so be sure to check the list of dormant projects before choosing that library.

Using Uv as an Installer (aider.chat)
It’s hard to reliably package and distribute python command line tools to end users. Users frequently encounter challenges: dependency version conflicts, virtual environment management, needing to install python or a specific version of python, etc.

Uv's killer feature is making ad-hoc environments easy (valatka.dev)
In my view, neither performance nor trying to be Python-aligned is what sets uv apart. Don’t get me wrong — try switching from uv to Poetry, and you’ll quickly notice how sluggish it (poetry) feels. uv goes extra miles to adhere to PEPs, and IMHO it’s the go-to package manager for Python these days. But these aren’t the features that surprised me most.

I built an Gemini powered AI that detects and fixes Python errors with reasoning (medium.com)
In the ever-evolving landscape of software development, automated tools that can help diagnose and fix code issues are becoming increasingly valuable. Today, I’m excited to share a project that leverages Google’s Gemini model to automatically detect and fix errors in Python code. This tool not only identifies issues but also provides reasoned explanations for its fixes, making it an excellent learning resource for developers.

Show HN: Tinyhnsw – The Littlest Vector Database (github.com/jbarrow)
TinyHNSW is a tiny, simple vector database. It weighs in at a measly few hundred lines of code. It's built on a straightforward (but not fast) implementation of HNSW in Python with minimal dependencies. It has an associated set of tutorials that build up to understanding how HNSW works, and how you can build your own TinyHNSW.

How to debug Python code in Visual Studio Code (qodo.ai)
Remember when finding Python bugs meant peppering your code with print statements? Well, those days are over. Visual Studio Code packs a punch when it comes to Python debugging. Think breakpoints that trigger only when your conditions match, real-time variable tracking, and the ability to freeze time in your code execution. Whether you’re hunting down race conditions or memory leaks, these tools will make your debugging sessions so much more productive.

Weak references and garbage collectors (bernsteinbear.com)
From 2018 to 2021, I worked on a greenfield Python runtime called Skybison. One of its major differences from CPython was that it used a moving garbage collector (GC). This I understood in theory—I knew that it ran when the heap filled up, knew we needed handles to update pointers in the runtime’s code, had read the Moon paper (PDF)—but the other day, I wanted to implement weak references and couldn’t immediately figure it out.

I'm seeing a stream of "year in review" blog posts about all sorts of topics pop up to coincide with the start of 2025. I'm not sure if this is going to be a new tradition for me, but to follow this trend in this article I'm going to give you my review of the most interesting things that happened in the Flask ecosystem in 2024.
