  • Intel Icelake Brings New Top-Down Performance Counters

  • Python Logging: A Stroll Through the Source Code

    The Python logging package is a a lightweight but extensible package for keeping better track of what your own code does. Using it gives you much more flexibility than just littering your code with superfluous print() calls.

    However, Python’s logging package can be complicated in certain spots. Handlers, loggers, levels, namespaces, filters: it’s not easy to keep track of all of these pieces and how they interact.

    One way to tie up the loose ends in your understanding of logging is to peek under the hood to its CPython source code. The Python code behind logging is concise and modular, and reading through it can help you get that aha moment.

    This article is meant to complement the logging HOWTO document as well as Logging in Python, which is a walkthrough on how to use the package.
