Introduction The architecture of ARM processor has become increasingly popular in embedded systems and mobile devices due to its low power consumption, high performance, and low cost. It is widely used in development of operating systems such as Windows CE and Linux. In this article, we will be discussing ARM calling conventions on Windows CE and Linux. What is a Calling Convention? A calling convention is a set of rules that dictate how function calls are made in a program. These rules are used to define how arguments are passed, how return value is handled, and how stack is managed ... Read More

Prerequisites Before installing Eclipse plugins, you need to make sure that you have Eclipse installed on your Ubuntu machine. If you don't have Eclipse installed, you can easily download it from official Eclipse website. ... Read More

Multi Pointer X (MPX) support is a feature of X Window System that enables multiple users to interact with a single computer at same time, each with their own keyboard and mouse. This is useful in situations where several people need to work on a single computer simultaneously, such as in collaborative environments or for teaching purposes. In this article, we will explore features and benefits of MPX support, as well as some examples of how it can be used. What is Multi Pointer X (MPX) Support? The X Window System is a popular windowing system used on Unix-like operating ... Read More

Introduction Subdomains are a great way to divide your website into different sections, making it easier for visitors to navigate and find what they’re looking for. But what if you need to create multiple levels of subdomains, such as blog.example.com or shop.blog.example.com? This can seem daunting, but with Apache2 and/or PHP, it’s actually quite simple. In this article, we’ll walk you through steps of creating multiple level subdomains with examples and sub-headings. What are subdomains? Subdomains are a way of creating a separate section of your website that has its own unique URL. For example, instead of having all of ... Read More

Introduction When working with data, it is often necessary to align multiple files based on a shared column. In this article, we will discuss process of aligning three files based on first column value. We will provide an example of three files and guide you through process of aligning them based on first column value. Why do we need to align three files? In data analysis, we often encounter situations where we need to combine data from multiple sources. In such cases, it is necessary to align data from different files based on a shared column. This is important because ... Read More

Introduction When developing software, there is a high chance that software might be used in various operating systems. Therefore, it is important to build software in a cross-platform manner to ensure compatibility with multiple operating systems. In this article, we will focus on cross-compiling static libraries from Linux for Windows. What is a Static Library? A static library is a file that contains pre-compiled code that can be linked with an executable program to create a single, self-contained executable. code in a static library is linked directly into executable, which makes it faster and more efficient than dynamic libraries. What ... Read More

Introduction As a system administrator or developer, it's important to be able to monitor and manage processes running on your system. One of key pieces of information you need to know is whether a particular process is currently running. In this article, we'll explore different ways to check whether a process with a given PID is running. What is a PID? Before we dive into ways to check if a process with a given PID is running, let's first define what a PID is. A PID (Process Identifier) is a unique identification number assigned to each process running on a ... Read More

Introduction In a networked computing environment, file systems allow users to access and manage files across different computers and storage devices. Network file systems (NFS) are a type of file system that enables remote file access and sharing between machines over a network. In NFS, a client machine can access files stored on a remote server as if they were on its local file system. One common question that arises regarding network file systems is whether they pre-fetch data to improve performance. In this article, we will explore concept of pre-fetching in network file systems and provide examples of how ... 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

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
