Code Wrangling at its Best
In Chapter 2 we taught the CPU how to call our code when something goes wrong: Now we will teach the machine how to call our code when hardware wants attention: This is the first step toward a living kernel. A timer interrupt eventually gives us scheduling. Keyboard input eventually gives us a kernel monitor

Today, we are beginning a new article series: “Writing a Linux-Style Operating System From Scratch.” In this series, we will walk step by step through the process of creating our own operating system from the ground up. Many operating system tutorials stop shortly after the system boots and prints a simple message on the screen.

A Beginners Guide Introduction Communication protocols are vital for enabling embedded devices to interact effectively. Three prominent protocols, Modbus, Standard Commands for Programmable Instruments (SCPI), and General Purpose Interface Bus (GPIB), stand out due to their widespread adoption in various industrial and testing environments. Recently, I had the opportunity to work on an embedded project

The world of programming languages is vast and ever-evolving. Over the decades, many languages have been introduced, gained popularity, and sometimes faded into obscurity. Yet, some languages, despite being widely criticized, have managed to maintain a strong foothold in the industry. Conversely, others, once heralded as the future, have declined in use. This article delves into this phenomenon, examining why some languages are resilient despite criticism, while others have fallen out of favor. We will explore these dynamics globally, understanding regional preferences and the historical context that has shaped the programming landscape.
