PyPI has completed its first security audit
The audit was conducted by Trail of Bits, a cybersecurity firm, and it focused on the Warehouse codebase and the cabotage container orchestration framework. The auditors found 29 advisories, but none were classified as high severity. The PyPI team has remediated all of the advisories that posed a significant risk.

What the Heck Are Monads?

Let’s create a Python Debugger together
Have you ever wondered how debuggers work? What happens when you set a breakpoint and hit it later? Debuggers are tools that we as developers use daily in our work, but few know how they are actually implemented. Here is a 4-part series on writing a Python debugger from scratch.

A quick look at destination-driven code generation
Picture this: you’re sitting there, writing a compiler, when all of a sudden you have to generate assembly. You have some intermediate representation (IR) but now you have to turn virtual registers into machine registers. This is called register allocation. Register allocation is tricky. It’s also slow. Even very fast register allocators like linear scan can dominate compile time. So let’s skip it. Let’s write a silly compiler in Python and see if we can improve the generated code without going full regalloc.

Querying every file in every release on the Python Package Index
This is an article about querying a dataset of Python package information. It discusses how to download the dataset and what information it contains. The dataset can be used to answer questions about Python package trends. For example, it can be used to track the adoption of new packaging metadata standards.
