While many know daemons from Greek mythology, we will learn what a daemon is in the world of software. If you ever manually installed software or a service on your server, a daemon runs in the background. This article will discuss what daemons are, the difference between a daemon and a process, the most common daemons, and how to use daemons on CentOS 6 and CentOS 7.

The Internet of Things (IoT) is a network of everyday objects or things embedded with electronics, sensors, and software, allowing for the collection and transfer of data. Connectivity enables such devices to communicate real-time data with other connected devices and act on the acquired data without human intervention. This concept, known as machine learning, allows us to exert significantly less effort to collect data and appropriately act on it. Instead, we can direct our energy towards analyzing the collected data for something of use to make a process or activity more efficient.

Introduction

In 2006, several Google engineers started to work on a Linux kernel feature called Cgroups (Control Groups) to limit and isolate hardware resource usage (e.g., RAM, CPU, disk I/O, network, etc.). Eventually, this functionality was merged with the Linux Mainline Kernel in 2008, and that paved the way for all containerization technologies that we use today, like Docker, Cloudfoundry, LXC, etc. 

Gogs is one of the most famous and widely used Git applications. It offers a low consumption alternative to other services like Gitlab or Gitea. Gogs is an open-source self-hosted Git service that provides all the essential features and benefits to set up a private and secure versioning control system.

The security of your network is of the highest priority, and an attack on your network could cost your business thousands, or even millions, of dollars. An intrusion detection system is one such system that can be used to monitor your network and receive alerts when suspicious activity is detected. In this article, we will explain what an intrusion detection system is and how it works.

What is Go?

Go is a statically typed and compiled programming language developed by Google and is often referred to as Golang due to its domain name. It was created by Rob Pike, Ken Thompson, and Robert Griesemer in 2007 to remove obstacles impacting compilation speeds, ease of programming, and safety. In today’s article, we will discuss the installation requirements of Go and how to install it on Ubuntu 20.04.

CentOS is without doubt one of the most widely used Linux distributions, mainly among Linux servers. It's a free, community-supported fork of Red Hat Enterprise Linux (RHEL) that provides a stable and fine-tuned operating system.
