Creating Custom Docker Networks
Docker provides several networking options for containers, such as bridge, host, and none, which are suitable for many basic use cases. However, as your containerized applications grow in complexity, you may need more control over how containers communicate.
APT vs. Snap: A Comprehensive Comparison of Ubuntu Package Managers
This guide should give readers insight into when to use each package manager and where they can benefit the most from APT or Snap. Let me know if you'd like more examples or additional sections!
How to Structure Your Git Repository for Scalability
The organization of your Git repository can significantly impact its scalability, collaboration, and maintainability. Effectively structuring your repository ensures that developers can easily navigate the codebase, understand the project’s structure, and work on it efficiently.
kernel error: Bluetooth: hci0: No support for _PRR ACPI methodThe kernel: Bluetooth: hci0: No support for _PRR ACPI method
A harmless ACPI warning about missing Bluetooth reset support may appear in your Ubuntu boot logs. This post explains what it means, why it happens, and how to fix or hide it — plus when it might actually signal a real Bluetooth issue.
Kernel Log Levels – Teaching the Kernel When to Speak Up (and When to Stay Quiet)
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.
Understanding VMware Workstation Network Adapter Types: Choosing the Right Option
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.
Testing OpenGL on Dual RTX 2080Ti without NVLink connection
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.
Kernel error: i915 0000:00:02.0: [drm] *ERROR* Atomic update failure on pipe A (start=20930 end=20931) time 663 us, min 2146, max 2159, scanline start 2108, end 2196
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.
Restricting dmesg Access – Teaching Your Kernel to Keep Secrets
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.
Understanding Docker’s Default Networking Modes
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.
