Building Your First Application

In this article by Mariano Reingart and Massimo Di Pierro, the authors of web2py Application Development Cookbook we will cover:

• Improving the scaffolding application

• Building a simple contacts application

• Building a Reddit clone

• Building a Facebook clone

The recipes in this article will provide examples of complete applications, comprising models, views, and controllers. They range from simple contacts applications to a more complex Facebook clone. Other recipes in this article will show you how to solve some recurrent problems that new users typically encounter, from adding a logo to creating a navigation bar.

SQL Server and PowerShell Basic Tasks

This article by Donabel Santos author of SQL Server 2012 with PowerShell V3 Cookbook, demonstrates scripts and snippets of code that accomplish some basic SQL Server tasks, using PowerShell. We will start with simple tasks, such as listing SQL Server instances and creating objects such as tables, indexes, stored procedures, and functions, to get you comfortable with working with SQL Server programmatically.

You will find that many of the recipes can be accomplished using PowerShell and SQL Management Objects ( SMO). SMO is a library that exposes SQL Server classes, which allows for programmatic manipulation and automation of many database tasks. For some recipes, we will also explore alternative ways of accomplishing the same tasks, using different native PowerShell cmdlets.

Even though we are exploring how to create some common database objects using PowerShell, I would like to note that PowerShell is not always the best tool for the task. There will be tasks that are best left accomplished using T-SQL. Even so, it is still good to know what is possible with PowerShell and how to do it, so that you know you have alternatives depending on your requirements or situation.

Continuous Delivery and DevOps FAQs

For a while now, there has been a buzz around the IT industry about something called continuous delivery and DevOps—strictly speaking that should be "some things" as continuous delivery and DevOps are actually two separate things.

You may have heard about them but may not fully understand what they are, why they are valuable and, should you wish to implement them, where to start from.

In this article by Paul Swartout, author of Continuous Delivery and DevOps: A Quickstart guide, we have tried to capture some common questions and provide some answers—an FAQ of sorts.

WebLogic Security Realm

This article by Luca Masini and Rinaldi Vincenzo, authors of Securing WebLogic Server 12c, covers every aspect you need to consider for activating an internal user and group structure.

Components - Reusing Rules, Conditions, and Actions

This article by Robert Varkonyi, author of Drupal Rules How-to, explains the benefits of using Components by creating a Condition that can be re-used in other rule configurations.

In this scenario, we want to perform some action when a node is being commented on. But we only want to execute the action if the node was not created by the super admin (that is, user 1) and the node is either an article, or has an image field (field_image).

Creating Interactive Graphics and Animation

In this article by Nivedita Majumdar and Swapnonil Banerjee authors of MATLAB Graphics and Data Visualization Cookbook, we will cover:

• Callback functions

• Obtaining user input from the graph

• Linked axes and data brushing

• The magnifying glass demo

• Animation with playback of frame captures

• Stream particle animation

• Animation by incremental changes to chart elements

Getting Started with Marmalade

Marmalade is a cross-platform solution that allows us to write the source code for a video game once in C++ (a language that most video game developers will already be familiar with) and then deploy it to a number of different platforms, including iOS, Android, and BlackBerry PlayBook.

In this article by Sean Scaplehorn, author of Marmalade SDK Mobile Game Development Essentials, we will be learning how to get the Marmalade SDK set up for development. While Marmalade is available in both Windows and Mac versions, the Windows version is the most developed of the two.
