In this article by Rafał Kuć and Marek Rogozinski the authors of this book Elasticsearch Server Third Edition , we dived into Elasticsearch indexing. We learned a lot when it comes to data handling. We saw how to tune Elasticsearch schema-less mechanism and we now know how to create our own mappings. We also saw the core types of Elasticsearch and we used analyzers – both the one that comes out of the box with Elasticsearch and the one we define ourselves. We used bulk indexing, and we added additional internal information to our indices. Finally, we learned what segment merging is, how we can fine tune it, and how to use routing in Elasticsearch and what it gives us. This article is fully dedicated to querying. By the end of this article, you will have learned the following topics: How to query Elasticsearch Using the script process Understanding the querying process
"Measuring programming progress by lines of code is like measuring aircraft building progress by weight." --Bill Gates In this article, by Tarun Arora , the author of the book Microsoft Team Foundation Server 2015 Cookbook , provides you information about: Configuring TFBuild Agent, Pool, and Queues Setting up a TFBuild Agent using an unattended installation
In this article by Gene Da Rocha , author or the book Learning SQLite for iOS we are introduced to the background of the Structured Query Language ( SQL ) and the mobile database SQLite . Whether you are an experienced technologist at SQL or a novice, using the book will be a great aid to help you understand this cool subject, which is gaining momentum. SQLite is the database used on the mobile smartphone or tablet that is local to the device. SQLite has been modified by different vendors to harden and secure it for a variety of uses and applications.
In this article by Raymond Camden , author of the book jQuery Mobile Web Development Essentials – Third Edition , we will look at dialogs, grids, and other widgets. While jQuery mobile provides great support for them, you get even more UI controls within the framework. In this article, we will see how to layout content with grids and make responsive grids.
In this article by Anshul Verma and Jitendra Zaa , author of the book Apex Design Patterns , we will discuss some problems that can occur mainly during the creation of class instances and how we can write the code for the creation of objects in a more simple, easy to maintain, and scalable way.
In this article by Rajdeep Dua , the author of the book Learning Docker Networking , we will look at an introduction of Docker networking and its components. Docker is a lightweight containerization technology that has gathered enormous interest in recent years. It neatly bundles various Linux kernel features and services, such as namespaces, cgroups, SELinux, and AppArmor profiles, over union filesystems such as AUFS and BTRFS in order to make modular images. These images provide a highly configurable virtualized environment for applications and follow a write once, run anywhere workflow. Applications can be as simple as running a process to a highly scalable and distributed one. Therefore, there is a need for powerful networking elements that can support various complex use cases.
In this article by Pethuru Raj , Jeeva S. Chelladhurai , Vinod Singh , authors of the book Learning Docker , we will cover the reason behind the Docker platform's popularity. Docker is an open platform for developers and system administrators of distributed applications. Building and managing distributed applications is beset with a variety of challenges, especially in the context of pervasive cloud environments. Docker brings forth a bevy of automation through the widely leveraged abstraction technique in successfully enabling distributed applications. The prime point is that the much-talked simplicity is being easily achieved through the Docker platform. With just a one-line command, you can install any application. For example, popular applications and platforms, such as WordPress, MySQL, Nginx, and Memcache, can all be installed and configured with just one command. Software and platform vendors are systematically containerizing their software packages to be readily found, subscribed, and used by many. Performing changes on applications and putting the updated and upgraded images in the repository is made easier. That's the real and tectonic shift brought in by the Docker-sponsored containerization movement. There are other advantages with containerization as well, and they are explained in the subsequent sections. (For more resources related to this topic, see here .)
In this article by Ernest Bruce , author of the book, Apply Pay Essentials , the author talks about actors and operations in the payment processing workflow. After the user authorizes the payment request, the user app , the payment gateway , and the order processing web app team up to securely deliver the payment information to the issuing bank, to transfer the funds form the user's account to the acquiring bank, and to inform the user of the transaction status (approved or declined).
In this article written by Joshua Johanan , Talha Khan and Ricardo Zea , authors of the book Web Developer's Reference Guide , the authors wants to state that "CSS properties are characteristics of an element in a markup language (HTML, SVG, XML, and so on) that control their style and/or presentation. These characteristics are part of a constantly evolving standard from the W3C."
In this article by Victor Wu , the author of the book Cisco UCS Cookbook , we will learn the concept of how to set up the EMC CLARiiON Storage connectivity of Cisco UCS B-Series server.
In this article by Yohan Wadia, the author of the book AWS Administration – The Definitive Guide , we are going continue where we last dropped off and introduce an amazing and awesome concept called as Auto Scaling ! AWS has been one of the first Public Cloud providers to provide this feature and really it is something that you must try out and use in your environments! This chapter will teach you the basics of Auto Scaling, its concepts and terminologies, and even how to create an auto scaled environment using AWS. It will also cover Amazon Elastic Load Balancers and how you can use them in conjuncture with Auto Scaling to manage your applications more effectively! So without wasting any more time, let's first get started by understanding what Auto Scaling is and how it actually works!
In this article by Ashwin Pajankar and Arush Kakkar, the author of the book Raspberry Pi By Example we will learn how to use different types and uses of cameras with our Pi. Let's take a look at the topics we will study and implement in this article: Working with a webcam Crontab Timelapse using a webcam Webcam video recording and playback Pi Camera and Pi NOIR comparison Timelapse using Pi Camera The PiCamera module in Python
