Today, we have multiple tools at our disposal when it comes to web application testing. Sometimes, it can be challenging to make the right decision when it comes to choosing a web application testing tool that fits your specific needs. There are endless factors that come into play when inspecting, verifying, and assessing code as multiple factors come into play that depends on the type of platform being used (e.g. a server cluster or virtual cloud-based system), the programming language being employed as well as the purpose of the web application itself.

Python is a general-purpose programming language designed for various uses. For example, websites, industrial robotics, and even games all use the same core technology.

Data in a MySQL/MariaDB database is stored in tables. A simple way of thinking about indexes is to imagine an extensive spreadsheet. This type of system is not always conducive to quick searching; that’s where an index becomes essential. If there is no index, then the database engine has to start at row one and browse through all the rows looking for the corresponding values. If this is a small table, then it is no big deal, but in larger tables and applications where there can be tables with millions and even billions of rows, it becomes problematic. As you can imagine, searching through those rows one by one will be time-consuming, even on the latest hardware. The solution is to create an INDEX (or more than one) for your data.

In this tutorial, we are going to take a look at how to get started with TensorFlow on CentOS. We will be covering two methods. First, we will take a look at installing TensorFlow in a Python virtual environment via the Python package manager pip. After that, we will walk through installing TensorFlow via the Anaconda package manager. Finally, we will cover building a TensorFlow pip package from source.

In this article, we will be discussing the various methods and techniques used to locate and uninstall the software from a Ubuntu/Debian based server. We will primarily be using the apt and dpkg commands on the command line.
