I started with screenshots and messy notes. One setting at a time. One benchmark at a time. Chaos. Then I moved Cyberpunk 2077 to the terminal, scripted the benchmark, and let Proton do the rest. No clicking. No guessing. Just repeatable, automated performance testing on Linux.
Native 4K on an RTX 2080 Ti sounds powerful — until 11GB of VRAM runs out. In Cyberpunk 2077, I test native rendering against DLSS, FSR, and XeSS to see what really improves performance — and what simply avoids the memory wall.
In modern software development, container orchestration is a crucial component for managing microservices and ensuring scalability and reliability. Docker Swarm, Docker's native orchestration solution, allows developers to deploy and manage containers in a clustered environment seamlessly.
Learn how to connect Docker CLI and Docker socket to a Jenkins container, enabling Jenkins to run Docker commands seamlessly. This hands-on guide explores mounting the Docker socket, installing the Docker CLI, and configuring Jenkins for efficient container management. 🚀
As modern applications increasingly shift toward containerized environments, the need for robust orchestration tools has never been more important. Docker Swarm, Docker's native container orchestration tool, simplifies the deployment, scaling, and managements.
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.
