Drawing on decades of engineering experience, the goal of this platform is to explore the intersection of modern software architecture, cloud computing, IoT, and AI, providingyou with the practical insights needed to build better systems and a stronger career. Want to dive deeper? Check out my latest books on technical architecture and career development: Modern C++ for Embedded C Engineers and The Durable Engineer.
Do you realize that 70% of legacy C embedded codebases have critical security vulnerabilities: memory leak, safety failures, difficult to expand. By industry statistics, over 60% of engineering bandwidth is consumed by the maintenance of those non-reusable legacy systems. If you feel the same pain in your project, this book is for you. It lets…
In embedded systems design, C++’s object-oriented features are typically introduced only after the platform hardware and RTOS have been fully initialized. In this article, I will demonstrate the significant benefits of using C++—instead of plain C—for low-level embedded tasks such as hardware register access. Access Hardware Register in C Style Following is how to update…
As embedded systems continue to power everything from consumer electronics and automotive controllers to medical devices and industrial IoT nodes, the demand for high performance and design flexibility has never been greater. Today’s embedded platforms must juggle real-time responsiveness, power efficiency, connectivity, security, and rapid development cycles — all within tight resource constraints. Choosing the…
By Keyuan Zhang Abstract Augmented Reality (AR), Virtual Reality (VR), and Extended Reality (XR) are rapidly evolving technologies that are reshaping digital experiences across industries. This article explores the technical challenges associated with these technologies, including hardware limitations, latency issues, and the need for high computational power. It compares AR, VR, and XR in terms…
