As per our first part, you now have your cluster all assembled and ready and want to install it. Do something with it already. For this we will have to download Raspbian Stretch Lite - a Linux distribution based on Debian and made especially for the Raspberry Pi. The ”Lite” version has an image file of 1,8GB and contains only the base system.

Over the course of the last four years, the amount of instances where Azure was mentioned in specific open source job openings has increased five fold. What we are seeing seems to mimic what Microsoft itself is saying. In a ZDNet article published during the latter part of last year, Microsoft executives discuss the growth they have seen in instances running Linux on Azure. From 2015 to 2018, Microsoft saw the number of Azure virtual machines running Linux grow from 25% to 50%. That is a quite notable growth trajectory in a fairly short time frame.

Nowadays Linux runs on almost anything. You can get a cheap PC and turn it into a media station or web server or whatever else you wish at no aditional cost. Hardware is cheap also. With the advent of the Raspberry Pi and similar small computer boards one can get a fully-functional PC for the price you'd usually pay for a sixpack of beer. In this LinuxConfig series we'll not only build a Linux computer; we'll build an entire Linux cluster with four nodes and learn how to manage it so that all the nodes respond at the same time to the same commands.

This guide will show how to configure a local repository server based on Ubuntu Bionic, but it can be adapted to a previous version of Ubuntu or even to any distribution using Aptitude as the main package management system, like Debian or Mint. You might typically want to setup a local repository to save Internet bandwidth.

Linux and Unix are often compared to each other. If the similarity in their names wasn't enough, Linux is technically a descendant of Unix, and they share a number of similarities in tool kits and overall structure.

Linux offers a wide range of choice, and music players are no exception. For quite a while, there have been fantastic options when choosing the perfect music player for your Linux computer.

They range from the minimal, light weight, and targeted to feature-rich multipurpose players capable of nearly anything. There's a great choice for every music fan on Linux.

Running a speed test can be very useful to verify the current state of an internet connection, for example, to verify that our ISP (Internet Service Provider) is respecting the parameters we are paying for, or to diagnose possible problems. One of the most common ways to check ping, download and upload values is to run a test from the speedtest.net website. The speedtest-cli program let us run the same test from our beloved command line interface.

Ebay is one of the biggest ecommerce sites. Many people use it to search and buy products, and many stores use it to enlarge their audience and expand their business range. If we want to operate programmatically on Ebay, for example to mass create or modify a set of items, or quickly confront prices, we must use the dedicated application programming interfaces. In this tutorial we will see how to prepare our working environment in order to use python to interact with the Ebay APIs.

This article is going to introduce Docker Compose and show how to put it to work for your needs. We will install it, write a simple Compose file and launch the container. We will then see how to launch multiple containers. Then we will see how to build images and lately how to use multiple Compose files to launch containers in different environments, like development and production, for example.

BlackArch is a penetration testing distribution, similar to Kali Linux, but it’s built on top of Arch Linux. In reality, BlackArch is really a pre-configured Arch installation with an extra repository full of security tools. As a result, you can add the BlackArch repository to a regular install of Arch and gain access to all the same tools.

KDEConnect has become the standard for interaction between Linux PCs and Android devices. It can handle most tasks and does so very well. For GNOME users, this usually means installing a ton of KDE dependencies on their system. It’s clunky, and it doesn’t integrate well with their desktop of choice.

Debian Stable is extremely stable, but it’s also very slow moving. As a result, you can get stuck with ridiculously outdated software.

Most Linux gaming came in the form of a handful of open source games or messy Wine configurations to get Windows games to work, albeit at a huge performance hit. Now, the picture is much different, thanks in large part to Steam.
