Introduction Choosing between a Real-Time Operating System (RTOS) and Embedded Linux has become far more nuanced than it was a decade ago. In the past, the decision was mostly based on available memory: if your device had less than 1 MB of RAM, you used an RTOS. If it had more than 32 MB, Linux […]
Every year, the same question comes up: “What embedded systems trends should I pay attention to?” Most answers tend to recycle the same mix of buzzwords, vendor roadmaps, and technologies that sound promising in slides but rarely survive contact with a real firmware project. What’s different heading into 2026 is that the industry is no […]
Embedded systems are everywhere. They power industrial robots, medical equipment, autonomous vehicles, smart home devices, telecommunications infrastructure, satellites, and countless IoT products that quietly perform their tasks every second of the day. Although these devices vary enormously in complexity, they all depend on one critical software decision that shapes performance, reliability, security, and long-term maintenance: […]
Linux continues to power much of the world’s digital infrastructure. From cloud platforms and enterprise servers to containers, IoT devices, networking equipment, and web applications, it remains the backbone of modern computing. This widespread adoption also makes Linux one of the primary targets for cybercriminals. Attackers know that compromising Linux systems can provide access to […]
Linux has earned its reputation as one of the most secure and reliable operating systems available. It powers everything from cloud infrastructure and enterprise servers to embedded devices, supercomputers, and much of the internet itself. But Linux isn’t secure by default. One lesson I’ve learned after working with Linux systems is that security rarely fails […]
Artificial intelligence has quietly become part of everyday open source development. AI-generated patches are appearing in small GitHub repositories, package updates, system libraries, kernel-adjacent projects, and enterprise software. This is no longer a hypothetical discussion about the future of software engineering—it’s today’s reality. Most maintainers are not trying to ban AI. They understand that modern […]
A new class of Linux privilege-escalation vulnerability has emerged, allowing local attackers to gain root access by exploiting a race condition in how the kernel handles copy-on-write (COW) behavior and page cache memory. The issue follows a familiar pattern seen in previous exploits such as Dirty Pipe, Dirty COW, Dirty Clone, and Dirty Frag — […]
Embedded Linux powers millions of connected devices, from industrial controllers and medical equipment to automotive systems, networking hardware, smart home products, and edge AI devices. Its flexibility, open-source ecosystem, and extensive hardware support have made it the operating system of choice for modern embedded products. That popularity also makes it one of the most attractive […]
Embedded CI/CD is often discussed in terms of automation, testing, and deployment speed. But in practice, most embedded pipelines fail long before those concerns matter. The real problem is simpler and more fundamental: the build is not reproducible. If you cannot reliably recreate the same binary from the same source code, everything built on top […]
When a security alert fires, the first instinct is usually panic followed by a quick check of familiar logs like /var/log/auth.log or journalctl. But while those logs are useful, they only tell part of the story — mainly authentication events and successful logins. To understand what actually happened during a compromise, you need a deeper […]
