You want a clear path to add a configuration option that shows up in menuconfig and builds cleanly without wasted rebuilds. I’ll walk you through a compact, practical approach that ties a tiny example driver into the kernel configuration, so the symbol appears where it should and obeys dependencies. We’ll cover the essential config and […]
Have you ever wished you could see exactly what your Kubernetes system does without changing any code? I’ve been there — frustrated by blind spots and long debug cycles. I want to show a fast path to clear, in-cluster insight that helps developers act now. With a single install on your platform, this open source […]
I often ask: can one lightweight tool give you kernel-level visibility without slowing your systems? We’ll show how a modern runtime approach brings real-time monitoring to where your applications run. I’ll explain how an eBPF-based driver runs verified programs safely inside the linux kernel and streams events to a user-space engine. That stream is evaluated […]
Have you ever wondered how to push high-volume traffic through commodity Linux without buying special hardware? I’ll show you a production-proven, open source solution that brings an L4 balancer into your stack with low overhead and predictable performance. We’ll walk through the moving parts you’ll touch: kernel fast path programs, a user-space control process, VIP […]
Can you safely extend the kernel without writing a monolithic driver? We set the stage for running eBPF on Windows with a clear, practical guide. I’ll explain what it is, why it matters, and how you can add trusted hooks with minimal friction. The Berkeley Packet Filter evolved into a flexible runtime for observability and […]
Can kernel-level programmability really replace heavy sidecars and fragile chains in cloud-native networking? We think it can—and I’ll show you why this shift matters for teams running containers at scale. Built in Go and powered by eBPF inside the Linux kernel, this open-source solution ties networking and security directly to container workloads. That means fine-grained […]
I’ve always loved tinkering with routers, especially when it comes to squeezing the most performance out of them. If you’re using OpenWRT and wondering how to take your network to the next level, enabling eBPF in the kernel might be the solution. eBPF, or Extended Berkeley Packet Filter, is a powerful tool that allows you […]
If you’ve experienced a blue screen with the dreaded “Kernel Security Check Failure” error while running Easy Anti-Cheat (EAC), you’re not alone. I’ve been there, too, and it can be incredibly frustrating—especially when you’re ready to dive into your favorite game. This issue commonly arises due to driver conflicts, corrupted system files, or outdated software. […]
Setting up a home lab can be a rewarding way to learn and test technical skills from the comfort of home. With a home lab, you can experiment with network setups, virtualization, and other IT projects. But to get the most out of a home lab, you need the right Linux distribution. Linux offers the […]
When it comes to programming for databases, choosing the right operating system can make all the difference. As a developer, I’ve always been on the lookout for tools that offer flexibility, security, and solid performance. Linux, a widely respected operating system in the open-source community, often comes highly recommended for database programming. But what makes […]
Contributing to the Linux kernel is both exciting and daunting. It’s the heart of one of the most important software systems in the world, powering millions of devices, servers, and computers globally. But how do you start? How do you go from simply using Linux to actually improving it? The idea of contributing to such […]
It can be frustrating to get the “Failed to Start Load Kernel Modules” error in Linux, especially if you do not know how to fix it. Feel free to relax, though, because this mistake happens a lot and is easy to fix. Even if you do not know much about Linux, this guide will make […]
If you’re like me, you’ve probably encountered some strange and frustrating errors while working with Linux. One that pops up from time to time is the “Missing Kernel Modules Tree for Module” error. It sounds complex, right? Don’t worry. In this guide, I’ll walk you through everything you need to know about this error, why […]
When working with open source software, selecting the right license for your project is one of the most important decisions you can make. The GNU Lesser General Public License (LGPL) is one of the key licenses within the open-source world, but many developers may not fully understand its purpose or benefits. If you’ve ever wondered […]
Debugging a kernel module in Linux might sound intimidating at first, but trust me, it’s much more manageable than it seems. Whether you’re new to kernel development or simply curious about how to fix bugs in your module, this guide will walk you through the essential steps, using simple and accessible tools. We’ll explore various […]
Choosing the right open source software license is a crucial step in the development process. It can shape the future of your project, influence its community, and even impact its commercial potential. But with a myriad of licenses available, how do you make the right choice? How do you navigate the legal language and understand […]
If you’ve spent some time working with Linux, you might have come across the term “kernel module.” If you’re wondering what exactly a kernel module is, how it works, and why it’s important, you’re in the right place. In this guide, I’ll explain everything about kernel modules in a way that’s easy to understand—even if […]
If you’re running CentOS 7 and looking to make the switch to CloudLinux, you’re in the right place. CloudLinux is a great option, especially if you’re managing a web hosting environment. It enhances server stability, security, and efficiency—qualities that are crucial for any hosting business. Upgrading from CentOS 7 to CloudLinux might seem like a […]
If you’ve been using Linux for a while, you’ve probably heard about the Linux kernel. It’s the core of the operating system, managing everything from hardware to software. But like all software, the kernel needs updates to fix bugs, improve performance, and add new features. If you’re a bit nervous about updating your Linux kernel, […]
Polling in Linux is a fundamental technique used in system programming to monitor multiple file descriptors to see if any of them is ready for some class of I/O operation (e.g., reading or writing). In environments where multiple I/O sources need to be managed, such as network servers, user interfaces, or event-driven systems, polling allows […]
