Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP) are the network protocols that are used to prevent loops from forming in the topologies of networks with redundant links. The speed of convergence is the primary difference between the STP and RSTP network protocols. STP takes a while to converge; on the other hand, RSTP converges significantly more quickly. In addition, RSTP provides fresh ideas, which include point-to-point connectivity and edge ports that speed the convergence process. RSTP network protocols offer faster convergence than STP protocols, and it is a more effective method of preventing loops in networks with ... Read More
Single-mode and multimode optical fibres are used in fibre optic communication systems. The diameter of the core, which impacts the number of light modes that can be broadcasted and the range over which the signal can be transferred, is the primary difference between the two. Read this article to find out more about Single-Mode Fiber and Multimode Fiber and how they are different from each other. What is Single-Mode Fiber? SMF stands for single-mode fiber. It can transmit only one mode of light because of its small core diameter. Single-mode fibres are used in cable television and backbone networks. It ... Read More
Context switching is an essential aspect of modern operating systems that enables them to efficiently manage resources available to them. Context switching is process of switching from one process to another in a multi-tasking environment. operating system does this by saving state of current process and loading state of next process. Monitoring context switches in Linux is a crucial task for system administrators, developers, and users who want to optimize performance of their systems. In this article, we will explore how to monitor context switches in Linux and why it is essential to do so. Understanding Context Switching in Linux ... Read More
Structures in programming languages like C and C++ are a collection of related data fields, which can be accessed and manipulated as a single entity. They are often used to group related data items into a single variable, making it easier to manage and work with complex data structures. However, as code bases grow and evolve over time, it is not uncommon for structures and their members to become unused or redundant. These unused structures and members can clutter code and make it more difficult to understand, maintain, and update. In this article, we will discuss some ways to locate ... Read More
Introduction Dynamic Link Libraries, also known as Shared Libraries, are collections of compiled code, data, and resources that can be loaded and executed by an application at runtime. Shared libraries are commonly used in development of Linux applications, and are an integral part of x86 architecture. In this article, we will explore process of linking with x86 shared libraries on Linux x64 systems. Understanding x86 Shared Libraries An x86 shared library is a file that contains compiled code, data, and resources that can be shared among multiple applications at runtime. Shared libraries are loaded into memory only when required by ... Read More
In recent years, touch technology has become increasingly popular, with smartphones, tablets, and laptops offering capability to interact with devices by simply tapping or swiping screen. However, what if you could use touch technology on your computer using a USB device? This is where concept of multi-touch enabled USB devices comes into play. In this article, we will explain what multi-touch enabled USB devices are, how to make a USB device multi-touch enabled, and provide examples of popular multi-touch USB devices in market. What are Multi-touch Enabled USB Devices? Multi-touch enabled USB devices are peripherals that are connected to a ... Read More
Introduction The corrupt stack problem is a common issue that programmers encounter while developing software in C and C++ programming languages. This problem can arise due to a wide range of reasons and can cause severe problems in functioning of program. In this article, we will explore corrupt stack problem in detail and look at some examples of how it occurs. What is a Stack in C and C++? Before we discuss corrupt stack problem, we need to understand what a stack is. In C and C++, a stack is a data structure that allows data to be stored and ... Read More
Introduction DBus is a widely used message bus system that facilitates communication between different software applications on Linux operating systems. It is used for inter-process communication (IPC) and allows applications to communicate with each other, even if they are running in different contexts. However, it can be difficult to determine which application or process is calling a specific DBus API. In this article, we will explore different methods for identifying caller of a DBus API on Linux. What is DBus? DBus is a message bus system used for inter-process communication (IPC) in Linux systems. It is a low-level, asynchronous protocol ... Read More
Introduction CUDA is a parallel computing platform and programming model created by Nvidia. It allows developers to use a CUDA-enabled graphics processing unit (GPU) to accelerate processing tasks in their applications. A CUDA context is a software environment that manages memory and other resources required by a CUDA application. A CUDA context is created when an application calls CUDA API, and it remains active until application releases it. One question that arises is whether it is possible to share a CUDA context between applications. In this article, we will explore this topic and discuss advantages and challenges of sharing a ...

Introduction Udev is a device manager used by modern Linux systems. It detects hardware changes and manages device nodes in /dev directory. Udev provides a flexible way to run scripts or programs in response to device events. This feature can be used to perform various tasks like automounting, launching backup scripts, and running long-running processes. In this article, we will discuss how to run long time processes on Udev events and provide examples to illustrate concepts. Understanding Udev Rules Udev rules are files that specify how Udev should handle device events. A typical rule consists of four parts: a match, ... Read More
