Security in the operating system heavily depends on regularly updating software. Some users overlook updates on even high-end machines, like MacBooks, missing out on critical security and performance improvements. Software vendors continually improve, fix bugs, and enhance security.
Ever wondered how Linux knows exactly how to power off a GPU or wake your Wi-Fi card? Meet ACPI — the quiet bridge between your laptop’s firmware and the Linux kernel that makes suspend and resume possible.
In this post, we’ll look at a simple script to limit active virtual consoles (TTYs) on Linux to TTY1 only. This can help reduce potential access, save system resources, or align with specific security requirements.
1. Introduction As you already know, I’ve been busy bringing my so-called "budget AI supercomputer" to life (quotation marks fully intentional). After all the assembly, cable wrangling, BIOS drama, and late-night Ubuntu installations, it was finally time
That’s why I’m paid so much!
Explore Linux sleep states (S-states) in depth. Learn what they are, how they differ, their impact on performance and power consumption, and how to configure and monitor them for optimal system efficiency.
Let’s walk through the process of converting a Jenkins Scripted pipeline into a Declarative one, step by step.
A Dockerfile is a text file that contains all the commands and instructions to assemble a Docker image. In essence, it is a blueprint for how Docker should build and configure the image, which will later be used to create a container.
Ubuntu offers stability, security, and freedom without the price tag. Discover why this open-source system stands out from other operating systems and how it can give you control over your computer — without the headaches.
Power management in Linux is a chain of hardware, ACPI, kernel, systemd, desktop, and apps working together. Learn how these layers interact to deliver smooth suspend/resume and long battery life.
Branches allow you to work on a different version of your project without affecting the original code. Once you're done making changes, you can merge the branch back into the main branch or discard it if needed.
After nearly a decade of loyal service, my Dell XPS 15 9550 got a major birthday upgrade. From fixing a sticky panel to adding new Wi-Fi, RAM, and storage, I brought this old warrior back to life—and it’s now ready for another decade of work.
