How to Optimize PUT Requests

 In this article by Naoya Hashiotmo , author of the book Amazon S3 Cookbook , explains how to optimize PUT requests, it would be effective to use multipart uploads because it can aggregate throughput by parallelizing PUT requests and uploading a large object into parts. It is recommended that the size of each part should be between 25 and 50 MB for higher networks and 10 MB for mobile networks.

Introduction to Odoo

 In this article by Greg Moss , author of Working with Odoo , he explains that Odoo is a very feature-filled business application framework with literally hundreds of applications and modules available. We have done our best in this book to cover the most essential features of the Odoo applications that you are most likely to use in your business. Setting up an Odoo system is no easy task. Many companies get into trouble believing that they can just install the software and throw in some data. Inevitably, the scope of the project grows and what was supposed to be a simple system ends up being a confusing mess. Fortunately, Odoo's modular design will allow you to take a systematic approach to implementing Odoo for your business.

ArcGIS – Advanced ArcObjects

 In this article by Hussein Nasser , author of the book  ArcGIS By Example we will discuss the following topics: Geodatabase editing Preparing the data and project Creating excavation features Viewing and editing excavation information

Testing Exceptional Flow

 In this article by Frank Appel , author of the book Testing with JUnit , we will learn that special care has to be taken when testing a component's functionality under exception-raising conditions. You'll also learn how to use the various capture and verification possibilities and discuss their pros and cons. As robust software design is one of the declared goals of the test-first approach, we're going to see how tests intertwine with the fail fast strategy on selected boundary conditions. Finally, we're going to conclude with an in-depth explanation of working with collaborators under exceptional flow and see how stubbing of exceptional behavior can be achieved. The topics covered in this article are as follows: Testing patterns Treating collaborators

Learning RSLogix 5000 – Buffering I/O Module Input and Output Values

 In the following article by Austin Scott , the author of Learning RSLogix 5000 Programming , you will be introduced to the high performance, asynchronous nature of the Logix family of controllers and the requirement for the buffering I/O module data it drives. You will learn various techniques for the buffering I/O module values in RSLogix 5000 and Studio 5000 Logix Designer . You will also learn about the IEC Languages that do not require the input or output module buffering techniques to be applied to them. In order to understand the need for buffering, let's start by exploring the evolution of the modern line of Rockwell Automation Controllers .

Creating a Web Server

 In this article by Marco Schwartz , author of the book Intel Galileo Networking Cookbook , we will cover the recipe, Reading pins via a web server .

Understanding TDD

 In this article by Viktor Farcic and Alex Garcia , the authors of the book Test-Driven Java Development , we will go through TDD in a simple procedure of writing tests before the actual implementation. It's an inversion of a traditional approach where testing is performed after the code is written.

Big Data

 In this article by Henry Garner , author of the book Clojure for Data Science , we'll be working with a relatively modest dataset of only 100,000 records. This isn't big data (at 100 MB, it will fit comfortably in the memory of one machine), but it's large enough to demonstrate the common techniques of large-scale data processing. Using Hadoop (the popular framework for distributed computation) as its case study, this article will focus on how to scale algorithms to very large volumes of data through parallelism. Before we get to Hadoop and distributed data processing though, we'll see how some of the same principles that enable Hadoop to be effective at a very large scale can also be applied to data processing on a single machine, by taking advantage of the parallel capacity available in all modern computers.

Walking You Through Classes

 In this article by Narayan Prusty , author of Learning ECMAScript 6 , you will learn how ES6 introduces classes that provide a much simpler and clearer syntax to creating constructors and dealing with inheritance. JavaScript never had the concept of classes, although it's an object-oriented programming language. Programmers from the other programming language background often found it difficult to understand JavaScript's object-oriented model and inheritance due to lack of classes. In this article, we will learn about the object-oriented JavaScript using the ES6 classes: Creating objects the classical way What are classes in ES6 Creating objects using classes The inheritance in classes The features of classes

Meeting SAP Lumira

In this article by Dmitry Anoshin , author of the book SAP Lumira Essentials , Dmitry talks about living in a century of information technology. There are a lot of electronic devices around us which generate lots of data. For example, you can surf the Internet, visit a couple of news portals, order new Nike Air Max shoes from a web store, write a couple of messages to your friend, and chat on Facebook. Your every action produces data. We can multiply that action by the amount of people who have access to the internet or just use a cell phone, and we get really BIG DATA. Of course, you have a question: how big is it? Now, it starts from terabytes or even petabytes . The volume is not the only issue; moreover, we struggle with the variety of data. As a result, it is not enough to analyze only the structured data. We should dive deep in to unstructured data, such as machine data which are generated by various machines.

From Code to the Real World

 In this article by Jorge R. Castro , author of Building a Home Security System with Arduino , you will learn to read a technical specification sheet, the ports on the Uno and how they work, the necessary elements for a proof of concept . Finally, we will extend the capabilities of our script in Python and rely on NFC technology. We will cover the following points: ProtoBoards and wiring Signals (digital and analog) Ports Datasheets

Tappy Defender – Building the home screen

In this article by John Horton , the author of Android Game Programming by Example , we will look at developing the home screen UI for our game.
