Sneak Peek into a PDM Code Clinic

Dive into an 11-minute sneak peek from my latest PDM Code Clinic session! In this brief yet informative segment, we take a closer look at the factory pattern, abstract base classes, and the concept of dependency injection in Python. Through the lens of a space mission simulation (awesome Antonio!), we

Multiple Interpreters? Whaaaaat?

Multiple Interpreters? Whaaaaat?

I'd like to talk about the support for multiple interpreters, also known as "subinterpreters", in CPython since version 1.5, which was released in 1997. This feature is accessible through the C-API. The multiple interpreters work in relative isolation, allowing for innovative new methods for handling

Simple Namespace

Python's SimpleNamespace is a utility for creating simple object types. It's part of the types module in the Python Standard Library and provides a way to quickly and simply create a "dot notation" namespace for a collection of attributes.

How to Automate Trimming your GCP Artifact Registry Docker Images

Alright alright alright, so there is the gcr-cleaner if you want a shortcut. I like writing code so here's an alternative version that you can mould into a cloud function or a cli. I can't help it. I enjoy writing code, so here it is:

Python Decorators 102

Now that you know your way around decorators, you're starting to have more complex use cases and you want to figure out how to pass a parameter to your decorator. Using our @metadata example from Python Decorators 101 [https://www.antonio-one.dev/python-decorators-101/], we add some extra nesting

Python Decorators 101

Python Decorators 101

A lot has been written over time about these cheeky little creatures and I couldn't possibly shy away from throwing a bit of code together. Before I start, what is a decorator? It's a little monkey that adds extra functionality to your function (or class). Let&

So you want to be a programmer?

So you want to be a programmer?

Today, I have a rather peculiar story to share. Four years ago I started a MSc in Information Technology, because I felt that everyone around me was loaded with degrees and I was lacking with my failed Philosophy and Political Science and questionable Media and Communications BSc. How I ended

This UNTITLED article is a mini-adventure.

This is somewhat a bit of a "weird" title. Hopefully, I will be able to articulate my thoughts appropriately and do this mini-adventure the justice it deserves. Very recently, I luckily got a slot in an advanced python programming class with one Mr David Beazley [https://www.dabeaz.

Build a docker container with cryptography, locust and pypy

Some of you will ask why? Why are you doing this to yourself Mr One? At the time, I was writing a fastapi pypy vs python benchmark/comparison for a code-clinic and hit a few snugs that I'd love to share with you. So if your are a

Welcome back to another politically incorrect baby monster blog. Today our niche use-case will see us familiarising ourselves with more cool tech lingo and real life examples. Makefile What's a makefile you say? A makefile is generally used to group and execute small snippets of code. A little

Package your python app with poetry & docker

The combination of "package", "python", "poetry" and "docker" are words you may not hear very often these days as there is more than one way to skin a cat [https://www.bnd.com/living/liv-columns-blogs/answer-man/article181298616.html]. Today, I choose to

How to use the gcloud Pub/Sub emulator with pytest - Part 1

The original pubsub emulator [https://cloud.google.com/sdk/gcloud/reference/beta/emulators/pubsub] documentation is pretty cool. To get the emulator up and running requires some manual shell work even if it's running on your machine and for the purpose of automated testing it might not necessarily
