Gradle is a high-performance open-source build automation tool that makes it possible to build just about any type of software. It is highly configurable and extensible via a well-developed plugin ecosystem. Because build automation is an integral part of the consistent delivery of software projects, Gradle integrates seamlessly with multiple IDE’s, including Android Studio. This tutorial covers the manual installation of Gradle on Linux, MacOS, and Windows.
Pyenv is a fantastic tool for installing and managing multiple Python versions. It enables a developer to quickly gain access to newer versions of Python and keeps the system clean and free of unnecessary package bloat. It also offers the ability to quickly switch from one version of Python to another, as well as specify the version of Python a given project uses and can automatically switch to that version. This tutorial covers how to install pyenv on Ubuntu 18.04.
A dependency is defined as a file, component, or software package that a program needs to work correctly. Almost every software package we install depends on another piece of code or software to work as expected. Because the overall theme of Linux has always been to have a program do one specific thing, and do it well, many software titles utilize other pieces of software to run correctly.
Let’s review what dependencies are and why they are required. We all have, at one point or another, most certainly seen a message from our system when we were installing software regarding “missing dependencies.” This error denotes that a required part of the software package is outdated, unavailable or missing. Let’s review how to address those issues when we come across them on Ubuntu.
A PPA (or Personal Package Archive) is a software repository provided by members of the Ubuntu Linux community. Software contained in a PPA can be downloaded and installed via apt, Ubuntu’s defacto package management system.
Typically, PPA’s will contain new or updated software to existing packages that may not be available from the official Ubuntu package repositories. This allows users to have more granular control over when specific software packages are updated on their systems. It is important to be discerning when utilizing PPA’s and to only add a PPA from a trusted source.
The best reason for adding software via a PPA, is the server will get automatic updates to the installed software when updates are run.
Virtualenv is a tool that creates an isolated environment separate from other projects. In this instance, we will be installing different Python versions, including their dependencies. Creating a virtual environment allows us to work on a Python project without affecting other projects that also use Python. It will utilize Python’s core files on the global environment to run, thus saving you disk space while providing the freedom to use different Python versions for separate apps or projects.
Artificial intelligence (AI) is a term to describe a branch of computer science that is dedicated to creating intelligent machines that would learn to work and react like humans. The field of Artificial Intelligence is not limited to creating only high levels of machine learning, but also to utilize data input in a manner required to produce a needed result. AI has multiple varieties and characteristics. Some of these types are noted as follows.
PyCharm is an IDE (or Integrated Development Environment) for the Python programming language. It is a cross-platform development environment that is compatible with Windows, macOS, and Linux. It provides a tool that integrates code analysis, graphical debugging, unit testing, and also contains an integrated terminal that supports development on remote hosts and virtual machines.

Fancied for its capabilities in handling binary packages over the easy_installed packages manager, Pip enables 3rd party package installations. Though Python does sometimes come with Pip as a default, this tutorial will show how to install, check its version as well as some basic commands for using Pip on Ubuntu 16.04.
SaltStack is an open-source infrastructure management platform built on a dynamic communications bus. The main structure of SaltStack contains two main components for work: one Salt Master and several Salt Minions. Salt Master is the main control system used to send commands to Salt Minion and their configuration. Salt Minions (they are also called Nodes) are subsystems that work on managed servers and receive commands from the master, as well as their configuration. At least two servers are required for interaction settings. One for the Master and one for the node. All nodes are configured in the same way.
Keras is a Python-based high-level neural networks API that is capable of running on top TensorFlow, CNTK, or Theano frameworks used for machine learning. It can be said that Keras acts as the Python Deep Learning Library. Keras was created with emphasis on being user-friendly since the main principle behind it is “designed for human beings, not machines.” The core data structure of Keras is a model, or a way to organize layers.
