Introduction In the ever-evolving landscape of software development, the significance of rigorous testing cannot be overstated. Quality assurance, through systematic testing, not only ensures the detection and rectification of defects but also plays a pivotal role in shaping the ultimate quality of the product. …

Let’s see how we can improve the performance of our Python code when using eval. — I’m using Python 3.11 to run the code. So, let’s work with this snippet code: import math import random import time result_count = 100000 expression = "math.sin(v['x']) * v['y']" variable = dict() variable['x'] = [random.random() for _ in range(result_count)] variable['y'] = [random.random() for _ in range(result_count)] result = [0] * result_count v = dict() start = time.time() for index in range(result_count)…

Let it be clear, this is not another article to criticize the changes in Terraform’s licensing by HashiCorp. There are too many reasons to consider moving away from using Terraform. In this article, we will review some of the advantages of Pulumi over Terraform. This does not imply being a…

After 25 years since its creation, Python is finally going to be truly “multithreaded”. How is it possible that it survived until now (perhaps thanks to libraries developed in C or C++)? The big lie: Python is not multithreaded Python has had support for multithreading for many years through the threading module. …

The C4 model allows representing a software system with a set of diagrams that each describe in depth a different level of detail, oriented towards a specific target audience. — Intro The C4 model allows representing a software system with a set of diagrams, each describing in depth a different level of detail. …

Introduction Cybersecurity has emerged as one of the most significant concerns for organizations. Attacks and security breaches can have severe repercussions, both financially and reputation-wise. Administrative interfaces are particularly vulnerable, where unauthorized access can lead to the modification or extraction of critical data. …

If you come from Java, the Python ecosystem probably seems chaotic to you. Understandably, working with Maven or Gradle compared to working with Pip and Virtualenv is radically different. It’s like going from order to chaos. Fortunately, Poetry allows us to reconcile with the Python ecosystem with a comprehensive solution for dependency management and package building — What is Poetry? Poetry is a manager that addresses many of its shortcomings: it allows for pinning versions to easily replicate the environment, marking dependencies that are used only during development, resolving conflicts between packages thus facilitating their update, and so on. …

In the chaotic DevOps universe, GitOps represents the umpteenth attempt to simplify concepts and operations in the DevOps world. — What is GitOps ? GitOps emerged in the 2017, thanks to Alexis Richardson of Weaveworks, as an evolution of infrastructure-as-code and DevOps best practices that put Git at the heart of operations. Git is the single source of truth and the control mechanism for creating, updating or deleting components in our system architecture.

If you’re working with kubernetes, you’ll probable be multiclustering in the near future. Let’s go over how we can configure ArgoCD to work with them. — Multi-clusters in kubernetes There are multiple approaches to manage kubernetes clusters. Each one has its pros and cons, you can find more information in the following table below:
