Learn how kernel.printk controls what your Linux kernel says (and what it keeps to itself). We’ll explore log levels, security implications, and how kernel.printk = 3 3 3 3 helps your system stay silent, secure, and sensible.
VMware Workstation offers multiple network adapter options, each with specific configurations, use cases, and benefits. This post will dive into the differences between each type of network adapter in VMware Workstation, helping you determine the best choice for various scenarios.
Continuing my dual-GPU adventure, this post dives into OpenGL performance on Ubuntu 25.10 using two RTX 2080 Ti cards—no NVLink, no PRIME, no Optimus. We’ll test rendering behavior, driver differences, and benchmark real-world results with glxgears and glmark2.
Frequent i915 atomic update errors in your Linux kernel logs? On Dell XPS 15 laptops with hybrid Intel–NVIDIA graphics, these messages usually point to race conditions in the Intel i915 driver. Learn what causes them, how to fix or mitigate them, and when it’s safe to simply ignore the noise.
Learn how kernel.dmesg_restrict protects your Linux system by limiting who can read the kernel’s ring buffer. A small setting with a big security impact — keeping sensitive kernel messages away from prying eyes.
Docker offers a powerful and flexible networking model that enables containers to communicate with each other, the host, and the outside world. Networking is a crucial part of containerized applications, as it allows multiple services, often running in separate containers, to collaborate.
A deep dive into the wild side of Linux performance tuning — disabling mitigations, isolating cores, and bending the kernel to your will. This story walks you through the dangerous beauty of chasing every microsecond of speed.
Snap packages offer a more flexible and distribution-agnostic method of software installation that includes all the necessary dependencies within a single package, thus making it easier to distribute and install software across various Linux distributions.
While exploring my kernel logs, I found a harmless but annoying error about ALSA’s restore rules. Turns out, it’s a missing label in a udev rule! Here’s what caused it, why your sound still works fine, and how to patch it manually without waiting for Ubuntu’s update.
Jenkins is one of the most widely used tools for CI/CD. Integrating Jenkins with Kubernetes allows for a more scalable, efficient, and flexible CI/CD environment, enabling organizations to automate the build, test, and deployment processes in a cloud-native way.
Commit messages in Git are more than just a technical requirement; they are a form of communication between you and your collaborators (including your future self). Writing clear, descriptive commit messages can drastically improve the quality of a project’s history and make it easier to understand
