Several weeks ago I developed a package to ease the pain of instrumenting #Python code with #OpenTelemetry. Now, I have written a post in my blog explaining how to use it. Check it out!

Why not have a way to have automatic #OpenTelemetry instrumentation for your functions in #Python? I have created a package called otelize (pypi.org/project/otel...) that provides a decorator that creates a span for each function call.

Some days ago I was using #copilot for code generation and had a fragment of Queen's Bohemian Rhapsody in the test code I wanted to review. I kid you not, the AI responded by ignoring all my instructions and adding the next part of the verse.

AI is pretty useful for getting the scaffolding in a programming language. Forgot how to create a decorator in #python or don't want to create to a TypedDict by hand? The AI has your back!

I wrote a #python package for writing log messages with a background #thread.
It is a proof of concept but it led me to interesting new ideas and challenges, posible issues and improvements.

It’s the basic premise of async functions but done without the event loop.

Do you read code just for pleasure? I was intrigued about how #pylint works and took a look to some rules.

Simplicity in software engineering is a must. If you do nothing against the continuous complexity increase, you will pay. For sure you will face a hurdle while extending or maintaining your software that you will not be not be able to overcome.

Some days ago I learned how to patch objects in the setUp method with #unittest in #python. I used to patch objects via the @patch decorator, but I'm starting to think this is cleaner if the same object is mocked for all the test methods.

I developed and maintain a #python package to freeze objects called gelidum (github.com/diegojromero...). I've noticed that I have a bunch of users but they haven't given me any feedback. How do you approach your users to ask them for feedback?

Just asked #chatgpt how to improve my #python project github.com/diegojromero... and it surprisingly gave some good points.
A new use-case for the AIs (for me): getting feedback for an open-source project.

Been playing around with python a bit. type, metaclass and decorators to do a simple thing: enforce constants at class-level.

This project is in pre-alpha, but it has forced me to learn and refresh some concepts, so it has some value.
