In the world of containerization, optimizing the size of Docker images is crucial for improving application performance, reducing deployment times, and minimizing storage costs. One of the most effective techniques for achieving smaller images is the use of multi-stage builds.
AppArmor and SELinux are tools used to harden the security posture of Linux distributions. These tools, known as Linux Security Modules, provide mechanisms for restricting what programs and processes can do on a system, thereby adding a layer of security.
Debugging issues in a large codebase can be challenging, especially when you need to identify which specific commit introduced a bug. If you have hundreds or even thousands of commits in your Git history, manually checking each one to locate the problematic change is time-consuming and error-prone.
What should have been a simple benchmark turned into a deep investigation. The native Linux version obeyed every parameter, but Proton didn’t. Logs confirmed everything was correct—yet the game ignored the command. This is the story of chasing a single parameter that refused to work.
Switching Docker to rootless mode enhances security by running containers without root privileges. In this post, I’ll walk you through the setup, key benefits, and considerations to help you adopt a safer Docker environment.
Want smoother gameplay on Linux in minutes? These six tweaks from CPU governor and GRUB parameters to SSD scheduler and GPU power mode, can reduce frame-time variance by up to 15%, making games feel faster, more stable, and more responsive.
Jenkins can dynamically provision build agents using Docker Cloud, ensuring clean, isolated environments for every build. Learn how to configure Jenkins to spin up Docker containers as agents, connect the Docker socket, and streamline your CI/CD pipelines.
One of the most important aspects of working with Docker is building efficient and optimized Docker images. A well-optimized image not only reduces the size of the image itself but also speeds up the build process, improves security, and allows for faster deployment.
SSH connections is critical when managing remote servers or accessing your Ubuntu system remotely. By default, SSH allows password-based authentication, which can be vulnerable to brute-force attacks and unauthorized access. In this detailed guide, we'll explore how to enhance SSH security.
Discover the ultimate guide to Git, from setting up your first repository to mastering advanced workflows. This hands-on post covers everything: committing changes, managing branches, resolving conflicts, tagging releases, and exploring commit history.
Git hooks are powerful tools that allow developers to automate tasks and enforce coding standards within a Git repository. When used properly in a team setting, Git hooks can streamline development workflows, improve code quality, and enhance collaboration.
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.
