In this article by William Leemans , author of the book Red Hat Enterprise Linux Server Cookbook he has covered the following recipes: Managing yum history Creating a copy (mirror) of any (RHN) repository Configuring additional repositories Setting up yum to automatically update Configuring logrotate for yum Recovering from a corrupted RPM database
In this article by Jason Goodwin , the author of the book Learning Akka , we have covered how to set up your environment and how to create a project, we can proceed with creating some actor code in Akka and then understand how to validate this code. We will be using simple build tool ( SBT ), which is the preferred build tool for Scala projects, Play Framework and Activator also use this build tool under the hood. It's not complex and we will use it only for managing dependencies and building, testing, and running the applications. So, it should not be an obstacle to learn Akka.
In this article by Fernando Monteiro , author of the book AngularJS Directives Cookbook , will see explain how to build a navbar directive and adapt it to an AngularJS application. We will also explore some basic functionalities of AngularJS directives. We will use a Yeoman generator to facilitate our work and illustrate how to organize your directory structure following the AngularJS best practices from community. It is assumed that you have intermediate knowledge of developing applications using AngularJS and modern tools such as Yeoman, Bower, and Grunt. However, the following examples are exemplified didactically.
One of the most important parts of mastering a version control system is exploring project history, making use of the fact that with version control system, we have an archive of every version that has ever existed. Here, you will learn how to select, filter, and view a range of revisions, refer to revisions (revision selection), and also how to find revisions using different criteria. This article by Jakub Narebski , the author of Mastering Git , will introduce the concept of the Directed Acyclic Graph ( DAG ) of revisions and explain how it relates to the ideas of branches, tags, and current branches on Git.
In this article by Chris Simmonds , author of the book, Getting Started with Ionic , we will cover the various Ionic JS components.
In this article by Saurabh Chhajed , author of the book Learning ELK Stack , he has covered Logstash input plugins. Logstash has a variety of plugins to help integrate it with a variety of input and output sources. Let's explore the various plugins available.
In this article by Scott Gallagher , the author of Mastering Docker , we will be looking at Docker in production, pulling all the pieces together so you can start using Docker in your production environments and feel comfortable doing so. Let's take a peek at what we will be covering in this article: Setting up hosts and nodes Managing hosts and container Using Docker Compose Extending to external platforms Security
In this article by John Horton , author of the book Android Programming for Beginners , we will look at the lifecycle of an Android app. At first it might sound a bit strange that a computer program has a lifecycle, but it will soon make sense. We will see the phases an app goes through from creation to destruction and how this helps us know where to put our Java code, depending on what we are trying to achieve. In brief we will look at: The life and times of an Android app What the method overriding @Override is The phases of the Android lifecycle What exactly we need to know and do to code our apps A lifecycle demonstration miniapp Let's start learning about the Android lifecycle.
In this article by Robert Dempsey , author of the book, Python Business Intelligence Cookbook , we will cover the steps that you need to import a file and consequently retrieve, insert, update and delete, single and multiple records.
In this article by Dr. Hari M. Kudovely , the author of Learning Bayesian Models with R , we will look at Bayesian inference in depth. The Bayes theorem is the basis for updating beliefs or model parameter values in Bayesian inference, given the observations. In this article, a more formal treatment of Bayesian inference will be given. To begin with, let us try to understand how uncertainties in a real-world problem are treated in Bayesian approach.
