Play! Framework 2 – Dealing with Content

A web application always has, at some point, the need to deal with multiple types of content. Common content types include JSON, XML, HTML, but there could also be images or even videos to be stored and streamed. Play! 2 provides a clean way of dealing with such content types with the help of body parsers.

We won't cover the implementation details of such body parsers, because it's purely based on a functional concept, Iteratee, and thus their implementations are in Scala only. However, we'll see how they are used and how we can gain benefits from them.

In this article by Andy Petrella author of Learning Play! Framework 2, we'll update and clean up a bit of what we have been doing so far in order to enable several workflows. So we will only be using examples we have learned up to now. The following is what will be achieved:

• Make the Chat and Item classes persistent using Ebean

• Create a link between an item and a user (a user's reply in a chat)

• Introduce a new type, Image, that will be part of a chat as an attachment

• Enable a user to connect

• Browse all chat instances

• Allow the connected user to reply in a chat

• Allow the connected user to attach an image to a chat

• Show examples of UIs

• Create an action that outputs a requested image

• Create an action that provides an Atom feed of all chats which have specific users getting involved (kind of like following)

Making Money with Your Game

In this article by Davy Cielen and Arno Meysman authors of HTML5 Game Development with ImpactJS, we will take a quick look at the options you have for making money with HTML5 game development. Building games can be done purely as a hobby or as a profession. However, the latter requires you to build some pretty unique and successful games as the competition is quite steep. Thus, offering a unique gaming proposition, supported by a healthy dose of marketing, seems to be the way to go for most successful game developers. In this article we will cover:

• A few strategic options you have when going into game development

• Making money in the app circuit of Android and Apple

• The option of in-game advertising and how it applies to HTML5 games

• MarketJS as a way to sell your distribution rights to a publisher

Analyzing network forensic data (Become an expert)

Having some skill with Tshark and analyzing our network on a regular basis can help us greatly in identifying multiple security issues. Besides the network attacks previously seen, we can intelligently use Tshark to investigate security incidents whose origin is unknown. In this article by Borja Merino, author of Traffic Analysis with Tshark How-to, we will discuss a couple of examples, data exfiltration by a malicious user and an internal network intrusion.

Quick Start into Selenium Tests

In this article by Unmesh Gundecha, author of Instant Selenium Testing Tools Starter, we will show you how to record a test using Selenium IDE. During the recording, we will add some additional commands to the test and run the recorded test.

A test is a basic building block in Selenium IDE. It contains commands for navigation, test steps, and checks for expected versus the actual state of the application. In this article we will show you how to create your first test and execute this test with Selenium IDE.

Drilling Back to Source Data in Dynamics GP 2013 using Dashboards

In this article by Mark Polino, author of Building Dashboards with Microsoft Dynamics GP 2013 and Excel 2013, will walk you through the deployment of a dashboard. Once you deploy a dashboard, it's inevitable that someone will want more information. They won't believe a number and will want to know the detail that makes up a balance. A great way to manage this is to build a couple of dashboards. Usually, this looks like a primary dashboard with secondary dashboards that break out more information about sales, cash, or departments. We've done this on a very simple level with our Revenue and Net Income tabs. They provide additional detail to expand on the main dashboard numbers.

Another great way to deal with the need for detail, and to take your dashboard beyond what everyone else is doing, is to allow users to drill down into specific transactions or accounts in Microsoft Dynamics GP 2013. In this article, we will look at drill down options including:

• Hyperlinks

• Using drill downs present in GP 2013

• The structure of a drill down

• Building your own links with Drill Down Builder

• Drill downs in complex environments

.NET 4.5 Extension Methods on IQueryable

In this article by Shawn R. McLean, author of Instant .NET 4.5 Extension Methods How-to , we learn about the extension methods on IQueryable. IQueryable is used to operate mainly on databases. IQueryable<T>are an extension from IEnumerable<T>, hence, we can call all extensions and methods of IEnumerable<T>. A query using IQueryable can be built up on over time, before it hits the database. The query is executed once you execute an eager function such as ToList(), looping the data or attempting to use the values. IQueryable is used by providers such as LINQ to entities or LINQ to SQL.
