| Developing WebSphere Application Server Communication Enabled Application (CEA) widgets
The Communication Enabled Application (CEA) Dojo widgets that were first
released in the IBM WebSphere Application Server V7 Feature Pack for
Communication Enabled Applications and in IBM WebSphere Application Server V8
are now available in source code format as samples for creating your own CEA
widgets. This gives you the freedom and
flexibility to rebuild the widgets for whatever version of Dojo you need, and
customize them to suit your application requirements. This article describes
general CEA concepts and explains how you can use these widgets as a starting
point for your own widget development.

| Optimizing resource management in supercomputers with SLURM
The arms race of supercomputers is fascinating to watch as their evolving architectures squeeze out more and more performance. One interesting fact about supercomputers is that they all run a version of Linux. To yield the greatest amount of power from an architecture, the SLURM open source job scheduler (used by the Chinese Tianhe-IA supercomputer, and the upcoming IBM Sequoia supercomputer) optimizes resource allocation and monitoring. Learn about SLURM and its approach to parallelizing workloads in clusters.

| Introducing Riak, Part 2: Integrating Riak as a heavy-duty caching server for web applications
This article is Part 2 of a two-part series about Riak, a highly scalable, distributed data store written in Erlang and based on Dynamo, Amazon's high availability key-value store. For websites with heavy loads, a scalable caching solution can lighten the load on the application and database servers. This particularly applies to data that is read often but updated only occasionally. Explore an in-depth example of an online betting site and how you can use Riak to implement a caching solution. You also will learn to integrate Riak with an existing website and look at other Riak features such as search and how to use it to directly serve user requests. You will need a working Riak cluster if you want to follow along with the examples. You can find the steps for setting up a cluster locally in Part 1 of this series.

| Improve your XSLT 2.0 stylesheets with types and schemas
The type-aware and schema-aware features of XSLT 2.0 can greatly assist you when you
debug a stylesheet, and improve stylesheet quality and robustness in handling all
input data. Learn how to use type-aware and schema-aware XSLT 2.0 during the debugging
and testing process to avoid common issues with invalid paths, incorrect assumptions about
data types, and cardinalities. Also, find examples of XSLT stylesheets that contain errors
that would not be caught if schema-aware features were not in use, and discover how
explicitly specifying types results in useful error messages.

| Comment lines: Using an adapter service pattern to build a more flexible, low maintenance ESB
Integrating multiple systems in a point to point manner can be very time
consuming and expensive to maintain. One common approach to resolve this issue
is to introduce an Enterprise Service Bus (ESB), which replaces the point to
point approach with a single, centralized place to integrate systems, and does
so in a service-oriented manner. However, if done incorrectly, this can still
create maintenance headaches. Here is a look at a pattern that can “future
proof” your integration work, allowing for the upgrading or replacement of legacy systems without excessive additional integration work.

| Understanding Ajax vulnerabilities
Asynchronous JavaScript + XML (Ajax) is not a web technology; it is a collection of technologies
created specifically to build dynamic web applications. Because of its range of functions
and ease
of use, Ajax is one of the most widely used tools for building web applications today.
All applications, including those built using Ajax technologies,
are vulnerable
to exploits that compromise websites and the databases that drive them.
In this article, learn about some of the threats to Ajax technologies
and how to guard against them.

| Make your HTML pages smarter with RDFa 1.1 Lite
Resource Description Framework (RDF) has evolved into increasingly
pragmatic formats over time. RDF annotation (RDFa) has been particularly
successful as a system for annotating HTML documents inline on the web. It is
supported by Google and other search engines in the form of Rich Snippets. The
emergence of microdata and the Schema.org initiative applied pressure to
simplify RDFa even further. The W3C took action and produced a radically
simplified version: RDFa 1.1 Lite. In this article, learn about RDFa Lite, and
get a head start on producing and processing the shape of Rich Snippets to come.

Virtualization and cloud computing make it very easy to create new

images gets harder. New images are created because it is easier to create a
new image than it is to figure out what existing image might be reusable,
creating "image sprawl." Unless you address how to more effectively build and manage your virtual

capabilities, the Virtual Image Library and the Image Construction and
