The Quest for Faster Python
There seems to be a lot going on in the Python JIT compiler space. Facebook recently open-sourced Instagram’s Cinder runtime, Pyston 2 returned as an open-source project, and the Pyjion project from Microsoft continues to grow. But Python creator Guido van Rossum has suggested that Python developers in need of more performance should consider writing parts of their code as C extensions, or use the PyPy runtime. This article explores Pythons turbulent history with performance optimization.

How Performance Became the Nemesis of the Secure Python Code
While JIT compilers compete for Python performance improvements and some teams rush into asyncio adoption, one has to wonder what the outcome of additional complexity will be. This opinion piece argues that the cost of hurried and potentially unnecessary performance optimization is unstable and insecure code. It’s a good reminder that decisions about project dependencies should be thoroughly researched and made deliberately.

Fluent in Django: Get to Know Django Models Better
Django models are the single, definitive source of information about data in a Django application. That means that all the logic about your data should be located in the model—not in a view as too often can be seen. In this article, you’ll get to know Django models better including things like UUID fields, enumeration types, Meta classes, and custom .save() methods.

I Forgot How to Spellcheck
Throughout 2020, Victor Shepelev worked on porting the hunspell spellchecker to Python in a project called spylls. In this post he shares his thoughts on spell checking, noting that it is much more difficult than just comparing strings to an established dictionary. While the article is not technical, it’s a great read exploring some of the assumptions made by hunspell and how they fail in the real world.
