The C programming language was created more than 50 years ago, and it remains one of the most widely used languages today, particularly for embedded systems, operating systems and low-level software development. Since its creation in 1972, the C programming language has evolved significantly. Several standards have been introduced over the years to improve portability, […]
Nrfutil is a command-line utility developed by Nordic Semiconductor that helps users manage and interact with Nordic’s nRF devices, especially during firmware development, flashing, DFU (Device Firmware Update), and key management operations. In order to use Zephyr to develop firmware for an NRF microcontroller unit (MCU), Zephyr must first be installed. As it is a […]
In C programming, pointers are fundamental tools that allow direct manipulation of memory. However, when combined with the const qualifier, they can introduce subtle distinctions that often confuse both beginners and seasoned developers. At first glance, the terms const pointer and pointer to const might seem interchangeable, but they serve different purposes. This article explores […]
When working with C, efficiency in memory usage can be a critical factor, especially in embedded systems or low-level programming. One lesser-known yet powerful GCC compiler flag that can help optimize storage is -fshort-enums. This flag changes the way the compiler allocates memory for enumerations (enum), potentially reducing the size of compiled code. In this […]
In the world of C programming, the clarity and maintainability of your code often hinge on a seemingly simple yet crucial aspect: naming conventions. From variables to functions, constants to macros, the names you choose can significantly impact how easily others (and your future self) understand and work with your code. While the C language […]
This article delves into the concept of function prototypes in C, exploring their syntax, purpose, and benefits. Whether you’re a beginner learning the fundamentals or an experienced programmer looking to refine your understanding, mastering function prototypes is a foundational step toward writing efficient and maintainable C programs. In the C programming language, a function prototype […]
Hello everyone. This article is for beginners or casual Python users who do not need to know or remember the most commonly used commands related to the Python language. Here is a collection of useful shell commands for working with Python. These commands can help you manage virtual environments, install packages, debug code, and manipulate […]
Include guards are a mechanism used in C and C++ programming to prevent multiple inclusions of the same header file. They help avoid issues such as redefinition errors, which can occur when the same header file is included multiple times in a program.
Hi, today’s post will be short and concrete. As you have probably noticed, installing on Ubuntu anything that’s is not present on apt repository is not as simple as running one shell comand or an exe file like on Windows machines. Fortunately, it’s not very complicated, so don’t worry. Once you know where to find […]
Hi, today’s post will be very short. Recently I found out that there is a strange bug related to Python version upgrade. My terminal stopped working after I upgraded Python version from 3.10 to 3.11 on Ubuntu 22.04. Not only terminal, but also other preinstalled applications like “Software Updater”. I decided to write a short article about this, first to warn you and second to give you a quick fix.
