The client-server distributed ObjectGrid instances combines the resources of multiple JVMs on multiple servers. In this article by Anthony Chaves, we'll learn how to use the resources held by the ObjectGrid instance to co-locate data and business logic on a single JVM. Co-locating data and logic on the same JVM requires a different model of programming. This article deals with the DataGrid API which makes co-location possible. In this article, we'll explore:
- Concepts implemented by the DataGrid API
- The programming model for sending logic to ObjectGrid partitions
- Where we would use the DataGrid classes

You can use Moodle as it comes without having major design problems, but it's well worth paying attention to a few design principles that will enhance your users' language-learning Moodle experience. Before you begin, why not take a look at other Moodle sites and see what you like or don't like. Look at things such as layout, ease of navigation, use of color, and images. You'll find a list of thousands of registered Moodle sites at http://moodle.org/sites/.Read Formatting and Enhancing Your Moodle Materials: Part 1 in full

In this article written by Demetrio Filocamo, we are going to develop the contacts management feature of our application i.e the contact managers, which includes listing, adding, editing, and deleting contacts—all of this the Ajax way!
Moreover, we are going to learn new concepts about the RichFaces component framework and Ajax support.Read Build an Advanced Contact Manager using JBoss RichFaces 3.3: Part 1 in full
Managing the registered users of your website can be a time consuming process, particularly if you have a large number of them, all of whom have various roles. Each role or user profile has access to certain information or tasks (if they're administrative) within the scope of your website. You have the tools to determine the extent of their access by using the backend interface modules. To explain, we'll use the Party People website to show you how to stay on top of managing your users and their profiles.
In this article by Tracey Porst on User Management, we will look at the User Manager to deal with the scenarios that can, and inevitably will, arise in your role as content editor and web master. These include:
- Managing existing frontend and administrative users
- Establishing and editing new user accounts
- Managing username and password issues
- Dealing with problematic users
- Tying in user profiles with site contacts
- Communicating with users
One trap that many web site owners fall into is spending lots of time pulling in traffic but not offering anything to encourage visitors to return. This leads to a rather self-defeating cycle where the site owner is forced to constantly promote their site to keep bringing in the same number of visitors, eating up valuable time that could be spent improving the site in other ways.
Fortunately, a little time invested during the early days of building a site can pay off very well in terms of encouraging repeat visitors. In this article by Lesley Harrison, we will:
- Learn what is meant by making a site "sticky"
- Look at ways to build conversations with visitors through comments and contact forms
- Make our visitors feel like they are part of a community with gravatars, polls, and welcome messages
- Find out how to encourage visitors to subscribe to the site, and keep them coming back
In this two-part article, by Sandro Tosi you will see several examples of Matplotlib usage in real-world situations, showing some of the common cases where we can use Matplotlib to draw a plot of some values.
There is a common workflow for this kind of job:
- Identify the best data source for the information we want to plot
- Extract the data of interest and elaborate it for plotting
- Plot the data
Usually, the hardest part is to extract and prepare the data for plotting. Due to this, we are going to show several examples of the first two steps.Read Plotting data using Matplotlib: Part 1 in full
