When building Docker images, the choice of the base image can significantly impact the final image size, performance, and security. Lightweight base images, such as Alpine Linux, have gained popularity in the Docker community for their minimal footprint and efficiency.
When it comes to system administration, managing processes and services is one of the most important skills. Processes are programs that run on your Ubuntu system, and services are background processes that typically start when your system boots and continue running to provide essential functions.
Let’s use a practical example to guide us through this process. By the end of this tutorial, you'll understand how to commit changes selectively, review modifications, and manage staged and unstaged changes.
Running Steam on a dual-GPU Linux machine can feel like herding pixels through quantum chaos. In this guide, we’ll untangle NVIDIA offload magic, identify which GPU is doing the work, and show how to make Steam—and your games—use the right one every time.
