Firewalls are essential for protecting your system from unauthorized access and securing your network. Ubuntu, being a popular Linux distribution, comes with a simple yet powerful firewall utility called UFW (Uncomplicated Firewall).
Automate code quality checks in your Git workflow with pre-commit hooks! This detailed guide walks you through setting up pre-commit for multi-language repositories, including Python, Bash scripts, Dockerfiles, and YAML files. Learn how to configure it to catch errors early.
Learn how to check if a package is installed on Linux using different package managers like APT, YUM, DNF, Zypper, and Pacman. A quick reference to save time and avoid unnecessary re-installations.
The build is almost complete. In this chapter, I finish assembling the system, make some intentionally overcomplicated storage decisions, wrestle with cable management in a tiny case, forget about Secure Boot (again), and finally bring the whole machine to life under Ubuntu.
As Jenkins grows into an integral part of your CI/CD process, managing Jenkins configurations becomes crucial for maintaining consistency, tracking changes, and ensuring collaboration across teams. As we use version control systems to manage codebases, it’s best practice to version control Jenkin.
Container orchestration has become a fundamental practice in modern software development and operations, especially as applications grow in complexity and scale. While Kubernetes is widely regarded as a robust orchestration tool, Docker Swarm, Docker's native orchestration solution
Backing up your system is one of the most critical tasks in maintaining data integrity and ensuring business continuity. Whether you're a casual user or an advanced system administrator, losing important files or configurations can be catastrophic.
Automation is a key principle in DevOps and software development practices. By automating repetitive and error-prone tasks, you can improve code quality, reduce human errors, and accelerate the development process. Git hooks offer a powerful mechanism for automating various tasks.
Modern games don’t render more pixels because they can — they do it because they must. This post explores how DLSS and FSR work on Linux, what your hardware really needs, and how to make Ubuntu gaming-ready.
What began as a simple PC build quickly turned into a lesson in small cases, wrong cables, BIOS tuning, and patience. This is the story of squeezing modern hardware into an ultra-small case—and everything that went wrong before it finally worked.
What started as an AI server experiment quietly turned into a Linux-powered gaming system built to explore modern hardware, DDR5, and “ultra” CPUs—proof that curiosity is still the best reason to build a PC.
Jenkins is a highly extensible automation server, largely due to its vast ecosystem of plugins. However, managing plugins manually—especially in larger Jenkins instances—can become time-consuming and error-prone. Automating Jenkins plugin installation and configuration
