About LAMP> About LAMP # LAMP stack is a group of open source software used to get web servers up and running. The acronym stands for Linux, Apache, MySQL, and PHP.

Introduction> Introduction # Configuration management systems are designed to make controlling large numbers of servers easy for administrators and operations teams. They allow you to control many different systems in an automated way from one central location.

Introduction OpenVPN is an open-source virtual private network (VPN) server/client application which allows you to join a virtual network (similar to a LAN) securely. This tutorial will explain how to install and configure an OpenVPN server on a FreeBSD 10.

Introduction> Introduction # UFW, or Uncomplicated Firewall, is an interface to iptables that is geared towards simplifying the process of configuring a firewall. While iptables is a solid and flexible tool, it can be difficult for beginners to learn how to use it to properly configure a firewall.

Introduction> Introduction # The Python pandas package is used for data manipulation and analysis, designed to let you work with labeled or relational data in an intuitive way. The pandas package offers spreadsheet functionality, but because you’re working with Python, it is much faster and more efficient than a traditional graphical spreadsheet program.

Introduction> Introduction # Django is a flexible framework for quickly creating Python applications. By default, Django applications are configured to store data into a lightweight SQLite database file. While this works well under some loads, a more traditional DBMS can improve performance in production.

Introduction> Introduction # In this guide, we will be setting up a simple Python application using the Flask micro-framework on Ubuntu 14.04. The bulk of this article will be about how to set up the Gunicorn application server to launch the application and Nginx to act as a front end reverse proxy.

Introduction> Introduction # In this tutorial you’ll deploy a containerized Django polls application into a Kubernetes cluster. Django is a powerful web framework that can help you get your Python application off the ground quickly.

Introduction> Introduction # Node.js is an open source Javascript runtime environment for easily building server-side and networking applications. The platform runs on Linux, OS X, FreeBSD, and Windows, and its applications are written in JavaScript.

Introduction> Introduction # The more you operate on the command line, the more you will find that the majority of the commands you use are a very small subset of the available commands.

Introduction> Introduction # NFS, or Network File System, is a distributed filesystem protocol that allows you to mount remote directories on your server. This allows you to leverage storage space in a different location and to write to the same space from multiple servers easily.

Introduction> Introduction # Postfix is a mail transfer agent (MTA), an application used to send and receive email. In this tutorial, we will install and configure Postfix so that it can be used to send emails by local applications only — that is, those installed on the same server that Postfix is installed on.

Introduction> Introduction # Docker is a popular containerization tool used to provide software applications with a filesystem that contains everything they need to run. Using Docker containers ensures that the software will behave the same way regardless of where it is deployed because its run-time environment is consistent.

About Virtualmin> About Virtualmin # Virtualmin is a Webmin module which allows for extensive management of (multiple) virtual private servers. You will be able to manage Apache, Nginx, PHP, DNS, MySQL, PostgreSQL, mailboxes, FTP, SSH, SSL, Subversion/Git repositories and many more.

Introduction> Introduction # Neural networks are used as a method of deep learning, one of the many subfields of artificial intelligence. They were first proposed around 70 years ago as an attempt at simulating the way the human brain works, though in a much more simplified form.

Using loops in computer programming allows us to automate and repeat similar tasks multiple times. In this tutorial, we’ll be covering Python’s for loop. A for loop implements the repeated execution of code based on a loop counter or loop variable.

Introduction> Introduction # In this guide, you will build a Python application using the Flask microframework on Ubuntu 18.04. The bulk of this article will be about how to set up the Gunicorn application server and how to launch the application and configure Nginx to act as a front-end reverse proxy.

Introduction> Introduction # Setting up a firewall for your infrastructure is a great way to provide security for your services. Once you’ve developed a policy you are happy with, the next step is to test your firewall rules.

Introduction> Introduction # While many users need the functionality of a database management system like MariaDB, they may not feel comfortable interacting with the system solely from the MariaDB prompt.

Introduction> Introduction # GitLab is a great way to manage git repositories on a centralized server. While solutions like GitHub are a great option for many projects, they do not fit every team’s needs.
