Python 3.14 Is Here. How Fast Is It?
In November of 2024 I wrote a blog post titled "Is Python Really That Slow?", in which I tested several versions of Python and noted the steady progress the language has been making in terms of performance. Today is the 8th of October 2025, just a day after the official release of Python 3.14. Let's rerun the benchmarks to find out how fast the new version of Python is! Note: If you do not care ab

Python 3.14's new t‑strings add flexibility and power to the language's arsenal of string processing tools. They make it easy to distinguish between static and dynamic content—essential for safe web templating. That's why we're excited to introduce tdom, a brand-new toolkit that leverages t‑strings and brings Python web templates into the modern era. It's easy to use: write HTML in a t‑string and
PythonBPF - Writing eBPF Programs in Pure Python | mallya's blog
IntroductionPython-BPF offers a new way to write eBPF programs entirely in Python, compiling them into real object files. This project is open-source and available on GitHub and PyPI. I wrote it alongside R41k0u. Published Library with Future PlansPython-BPF is a published Python library with plans for further development towards production-ready use. You can pip install pythonbpf but it’s certain
Rye Tables vs Python/Pandas: A Different Way to Wrangle Data
Exploring tabular data across Rye, Pandas, and plain Python through three worked examples. If you’ve ever filtered a CSV in Pandas or written multiple nested for loops to group data in Python, you’ll probably find Rye’s take on the problem interesting. Rye is a small, homoiconic language inspired by Rebol and Factor. One of its most interesting value types is the Table. A first-class, immutable da
Python has had async for 10 years -- why isn't it more popular?
Python has had async for 10 years -- why isn't it more popular? The Python Documentary dropped this morning. In the middle of the documentary, there’s a dramatic segment about how the transition from Python 2 to 3 divided the community (spoiler alert: it didn’t in the end). The early versions of Python 3 (3.0-3.4) were mostly focused on stability and offering pathways for users moving from 2.7. Al
Litestar is worth a look
A few years ago at work, I had a project which offered an opportunity to look at the new generation of async-first, type-hint-driven Python web frameworks. For reasons which aren’t particularly relevant today, on that project I ended up choosing Litestar, which is the one that doesn’t have a ravenous all-consuming hype machine surrounding it. And I’m very glad I did, because today I’m more convinc
Following up on the Python JIT
Performance of Python programs has been a major focus of development for the language over the last five years or so; the Faster CPython project has been a big part of that effort. One of its subprojects is to add an experimental just-in-time (JIT) compiler to the language; at last year's PyCon US, project member Brandt Bucher gave an introduction to the copy-and-patch JIT compiler. At PyCon US 20
Reflections on 2 years of CPython’s JIT Compiler: The good, the bad, the ugly
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 alm
