In this article by Vinoo Das author of the book Learning Redis , we will see how Redis as a NOSQL data store, provides a loose sense of transaction. As in a traditional RDBMS, the transaction starts with a BEGIN and ends with either COMMIT or ROLLBACK . All these RDBMS servers are multithreaded, so when a thread locks a resource, it cannot be manipulated by another thread unless and until the lock is released. Redis by default has MULTI to start and EXEC to execute the commands. In case of a transaction, the first command is always MULTI , and after that all the commands are stored, and when EXEC command is received, all the stored commands are executed in sequence. So inside the hood, once Redis receives the EXEC command, all the commands are executed as a single isolated operation. Following are the commands that can be used in Redis for transaction: MULTI : This marks the start of a transaction block EXEC : This executes all the commands in the pipeline after MULTI WATCH : This watches the keys for conditional execution of a transaction UNWATCH : This removes the WATCH keys of a transaction DISCARD : This flushes all the previously queued commands in the pipeline
In this article by Alexandru Vaduva , author of the book Learning Embedded Linux Using the Yocto Project , you will be presented with information about various concepts that appeared in the Linux virtualization article. As some of you might know, this subject is quite vast and selecting only a few components to be explained is also a challenge. I hope my decision would please most of you interested in this area. The information available in this article might not fit everyone's need. For this purpose, I have attached multiple links for more detailed descriptions and documentation. As always, I encourage you to start reading and finding out more, if necessary. I am aware that I cannot put all the necessary information in only a few words. In any Linux environment today, Linux virtualization is not a new thing. It has been available for more than ten years and has advanced in a really quick and interesting manner. The question now does not revolve around virtualization as a solution for me, but more about what virtualization solutions to deploy and what to virtualize.
In this article by Tiago Antao , author of Bioinformatics with Python Cookbook , you will process next-generation sequencing datasets using Python.
The Banana Pi is a single-board computer, which enables you to build your own individual and versatile system. In fact, it is a complete computer, including all the required elements such as a processor, memory, network, and other interfaces, which we are going to explore. It provides enough power to run even relatively complex applications suitably. In this article by, Ryad El-Dajani , author of the book, Banana Pi Cookbook , we are going to get to know the Banana Pi device. The available distributions are mentioned, as well as how to download and install these distributions. We will also examine Android in contrast to our upcoming Linux adventure.
In this article by Makzan , the author of HTML5 Game Development by Example: Beginner's Guide - Second Edition has discussed the new highlighted feature in HTML5—the canvas element. We can treat it as a dynamic area where we can draw graphics and shapes with scripts.
In this article by Alexander Bruy and Daria Svidzinska , authors of the book QGIS By Example , you will learn how to work with styles, including saving and loading them, using different styles, and working with the Style Manager.
In this article by Roberto Ulloa , author of the book Kivy – Interactive Applications and Games in Python Second Edition , we will learn how to use the progression of a video to display subtitles at the right moment.
In this article by Simone Fiorini and Arun V Gopalakrishnan , authors of the book Mastering jBPM6 , we will build our first BPM application by using the jBPM tool stack. This article will guide you through the following topics: Installing the jBPM tool stack Hacking the default installation configurations Modeling and deploying a jBPM project Embedding jBPM inside a standalone Java project This article gives you the hands-on flexibility of the jBPM tool stack and provides information on hacking the configuration and playing around.
In this article by William Rice , author of the book, Moodle E-Learning Course Development - Third Edition shows you how to use groups to separate students in a course into teams. You will also learn how to use cohorts to mass enroll students into courses.
In this article by Jon Hoffman , author of the book Mastering Swift , you will learn how to use Apple's system configuration API to figure out what type of network connection we have. If we are developing applications for a mobile device (iPhone, iPod, or iPad), it is e essential to know if we have a network connection and what type of connection it is.
In this article by Rimantas Mocevicius , author of the book CoreOS Essentials , has described CoreOS is often as Linux for massive server deployments, but it can also run easily as a single host on bare-metal, cloud servers, and as a virtual machine on your computer as well. It is designed to run application containers as docker and rkt , and you will learn about its main features later in this article. This article is a practical, example-driven guide to help you learn about the essentials of the CoreOS Linux operating system. We assume that you have experience with VirtualBox, Vagrant, Git, Bash shell scripting and the command line (terminal on UNIX-like computers), and you have already installed VirtualBox, Vagrant, and git on your Mac OS X or Linux computer. As for a cloud installation, we will use Google Cloud's Compute Engine instances. By the end of this article, you will hopefully be familiar with setting up CoreOS on your laptop or desktop, and on the cloud. You will learn how to set up a local computer development machine and a cluster on a local computer and in the cloud. Also, we will cover etcd , systemd , fleet , cluster management, deployment setup, and production clusters. In this article, you will learn how CoreOS works and how to carry out a basic CoreOS installation on your laptop or desktop with the help of VirtualBox and Vagrant. We will basically cover two topics in this article: An overview of CoreOS Installing the CoreOS virtual machine
