Mumble is an open-source, low-latency, high-quality voice chat software primarily designed for online gaming communities. It provides a secure, reliable, and scalable communication system for users. Mumble has two components: the client software that users install on their machines, and the server software (called Murmur) that runs on a dedicated server. This tutorial covers how to install and configure a Mumble server on Linux CentOS 7. Prerequisites Before starting the installation process, ensure the following requirements are met: A Linux CentOS 7 server with root access An SSH client such as PuTTY or Terminal A non-root ...
Read MoreWhat is an application and system program?
Application programs and system programs are two fundamental types of software that serve different purposes in a computer system. Application programs are designed for end-users to perform specific tasks, while system programs manage and control the computer's hardware and provide services to other software. Application Program Application programs are software designed for end-users to accomplish specific tasks or solve particular problems. These programs provide a direct interface between the user and the computer system, allowing users to perform activities like word processing, web browsing, gaming, or multimedia editing. Application programs are loaded into the system based on ...
Read MoreExclude grep From ps Results on Linux
The ps command in Linux displays information about running processes on a system. It provides a snapshot of current processes, including process ID (PID), user ownership, CPU and memory usage, and the command that started the process. When using ps with grep to filter processes, the grep command itself often appears in the results, which can be unwanted. Common Problem with ps and grep When searching for specific processes using ps | grep, the grep command itself appears in the output because it's also a running process at that moment: $ ps aux | grep ssh ...
Read MoreCopy Files from Docker Container to Local Machine
If you are working on a project that requires frequent copying of files and folders either from container to your local machine or from the local machine to the container, Docker provides an easy and simple way to do that. If you have already built a Docker image which is of large size and contains a large number of files and in the midst of the project you want to copy files to and from the container, it's highly inefficient to put the files in the Docker build context and build images repeatedly. Instead, Docker allows easy copying of files ...

Red Hat Enterprise Linux 7 (RHEL 7) is a popular operating system used in many enterprise environments. As a system administrator, automating the installation process of RHEL 7 can be very beneficial. Automating installation saves time and reduces the risk of human error. Kickstart is a tool that can be used to automate the installation process of RHEL 7. In this article, we will look at how to use Kickstart to automate RHEL 7 installations. What is Kickstart? Kickstart is a tool used to automate the installation process of RHEL 7. With Kickstart, you can create a script ...
Read MoreWhat are Good and Bad Interface Designs?
Generally, an interface acts as a shared boundary across two or more separate components of a computer system that are used to exchange information. Those exchanges can be between software, computer hardware, peripheral devices, humans and computers. Interface design is crucial in operating systems as it determines how users interact with system resources and applications. Interface design directly impacts system usability, efficiency, and user satisfaction. A well-designed interface reduces cognitive load and allows users to accomplish tasks with minimal effort, while a poorly designed interface can lead to errors, frustration, and decreased productivity. Good Interface Design Good ...
Read MoreLearn Why 'less' is Faster Than 'more' Command for Effective File Navigation
The more and less commands are essential pagers used to view text file contents one screen at a time. While both serve similar purposes, less offers superior functionality and performance compared to more, making it the preferred choice for file navigation in Unix-like systems. Understanding the 'more' Command The more command is a basic pager that displays file contents sequentially, originally allowing only forward navigation. Modern implementations support limited backward movement. Basic Usage $ more /var/log/dpkg.log 2016-12-02 11:30:45 startup archives unpack 2016-12-02 11:30:45 install python-ptyprocess:all 0.5-1 2016-12-02 11:30:45 status half-installed python-ptyprocess:all ...
Read MoreDifferentiate between Interface design and Interaction design
Interface design and interaction design are two fundamental concepts in user experience that work together to create effective digital products. While they are closely related, they focus on different aspects of the user experience and serve distinct purposes in the design process. User Interface Design User Interface (UI) design focuses on the visual and tangible elements that users directly interact with to accomplish tasks. It establishes the visual framework through which users will engage with a product or system. The primary aim of UI design is to enhance the product's visual appeal, technological quality, and overall usability. ...
Read MoreLinux and Unix Test Disk I/O Performance with DD Command
The DD command is a powerful command-line utility in Linux and Unix systems that can test hard disk I/O performance by measuring read and write speeds. This article demonstrates how to use DD command to benchmark your storage device performance effectively. What is DD Command? DD is a command-line utility for Unix and Unix-like operating systems where the primary purpose is to copy and convert files. It reads from an input source and writes to an output destination, making it ideal for disk performance testing by creating controlled I/O operations. Testing Write Performance Open your Linux ...
Read MoreHow to Check Logs Using journalctl in Linux
Logs are a crucial component of any Linux system, as they provide a record of system activity, including system events, user actions, and system processes. journalctl is a command-line utility for viewing and managing logs on Linux systems using the systemd initialization system. It provides powerful filtering and formatting capabilities to help administrators monitor system health and troubleshoot issues effectively. Basic journalctl Commands The journalctl command can view and filter system logs for all system services, the kernel, and specific services or users. It can display the entire journal, view logs from a specific boot, or filter logs ...
