Events and Signals

Events

by Ken Finnigan | July 2013 | JBoss Java Open Source

In this article by Ken Finnigan author of JBoss Weld CDI for Java Platform,we are going to find out about events within CDI, such as how they are fired, how we listen for new events, what we can use as an event payload, and how we can narrow what events we can listen to and fire. All of these we will discover while staying within the boundaries of typesafe Java, making our runtime less error-prone.

Events may be produced and consumed by beans of our application, but there is absolutely no coupling between the bean producing an event and the one consuming it. This allows our beans to interact without any coupling or compile-time dependencies between them.

Event Delivery Network with Oracle SOA Suite 11g R1

by Demed L'Her Heidi Buelow Jayaram Kasi Manas Deb Prasen Palvankar | September 2009 | Oracle

In a service-oriented world, a level of abstraction is needed for creation and use of events using business semantics, without the publisher or subscriber of the event ever having to worry about the mechanics of messaging. Oracle SOA Suite 11g addresses this with the introduction of a new feature in the form of the Event Delivery Network.

In this article by Heidi Buelow, Manas Deb, Jayaram Kasi, Demed L'Her and Prasen Palvankar, we will work with events using the unified services and events platform of Oracle SOA Suite 11g to provide an event-handling solution.

ER Diagrams, Domain Model, and N-Layer Architecture with ASP.NET 3.5 (part1)

by Vivek Thakur | June 2009 | .NET Architecture & Analysis Microsoft

In this two-part article by Vivek Thakur, we will learn about ER Diagrams, Domain Model, and N-Layer Architecture with ASP.NET 3.5. The 1-tier 1-layer architecture is the default style in ASP.NET and Visual Studio 2005/2008. To overcome the limitations of this style, we can further break the application code into n-layers, where the number "n" actually depends on the project requirements.

In this article we will:

  • Learn the 2-layer style
  • Understand ER diagrams
  • Understand what a domain model is, and what UML relationships are
  • Learn the 3-layer style
  • Learn about object data source controls

Enterprise Instant Messaging using Sametime in IBM Lotus Notes 8.5

by Karen Hooper | August 2010 | Enterprise Articles IBM

This article covers the benefits and features of Lotus Sametime, which is a built-in chat and presence awareness tool. There are many advantages that come with Sametime. First, it is relatively low cost; it is not like a cell phone call where one is charged by the minute. Another advantage is the ability to see who is available to chat, which is fantastic when we're communicating with people who are outside of their time zone or across the world, or even one floor down in their office building. Sametime is instant because we're online—people can start a chat with someone when they see them online and they can instantly respond.

In this article, by Karen Hooper, author of IBM Lotus Notes 8.5, we will learn:

  • What is Sametime
  • How to use Sametime
  • Understanding availability status
  • Adding Sametime contacts
  • Chatting with contacts
  • The chat window options
  • Setting Sametime preferences
  • Sametime help

Enlighten your desktop with Elive

by Mayank Sharma | July 2007 | Open Source

Unless you're an old Linux user, you've only probably used the KDE, GNOME or Xfce desktop environments. But since the time when these desktops were in their infancy, the Enlightenment desktop environment has been impressing users. Bringing this mature, visually appealing environment to new Linux users is what the Elive distribution is all about.

On its website, Elive claims to be more than a simple Linux distro, rather a work of art. I might be a little biased but that's probably true. One look at Elive's graceful and charming environment and you are sold. And unlike today's 3D visualization, Elive can run efficiently on older systems as well with a gamut of desktop applications. Its got detailed documentation Wiki and an active forum to answer questions.

Elive's been in development for several years now and in fact is so popular that its developer, Samuel "Thanatermesis" F. Baggen, works on it full time. In this month's article, Samuel explains his reasons for spinning Elive and how the distro has evolved over the years.

Enhancing Your Math Teaching using Moodle 1.9: Part 1

by Ian Wild | December 2009 | Moodle Open Source

In this article by Ian Wild, we will be looking at taking our current resources and converting them over to Moodle. I'm going to concentrate on the kinds of resources we math teachers usually have. They usually come in two flavors. The first are the "static" resources: PowerPoint presentations, documents provided by publishers (such as resources provided on a CD-ROM at the back of a textbook or downloadable from the publisher's website). In this article, we'll focus on these static resources. Again, those are the resources math teachers and lecturers usually like to convert to Moodle. The other type of resources are "interactive" resources.

In this article we will learn the following:

  • How to create math-related PowerPoint presentations and, using the content sharing website SlideShare, include them in our Moodle courses along with a suitable narration
  • How to extract math-related videos from YouTube and include them in our courses
  • What a screencast is and how it can be used to explain mathematical concepts
