Systemd orchestrates Linux suspend and resume. From systemd-logind deciding when to sleep, to inhibitors blocking it, to pre/post scripts and sleep.conf tuning defaults, learn how systemd coordinates kernel and user-space for reliable power management.
Large Docker images slow deployments and waste storage. Multi-stage builds solve this by separating build and runtime environments, keeping only what’s needed in the final image. Learn how to optimize your images for speed, security, and efficiency
Ubuntu comes in two flavors: Desktop for everyday use with a friendly interface, and Server for running websites, apps, and services behind the scenes. Learn how they differ and which one is right for your needs.
Branching strategies shape how your team collaborates in Git. From feature branches to Git Flow and GitHub Flow, each approach offers unique benefits. In this post, we’ll explore popular strategies and best practices to keep your workflow smooth and your codebase clean.
I benchmarked my home AI server with 88 cores against all my other machines, from an old MacBook Air to a modern M1 MacBook Pro. The results show surprising differences in single-core vs. multi-core performance—proving raw core count isn’t everything.
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.
