Adding rounded corners to an object in your HTML should be easy. Heck, open up Photoshop or your favorite image editor and it is easy to around rounded corners to any rectangle you create. When it comes to creating Web pages it is a different matter. Creating rounded corners to a block of text, a tab or a background is not easy. The only effective way to add a rounded corner is to create a HTML table with image files that look like corners. This is a lot of work and not very easy to update. HTML5’s update to Cascading Style Sheets, CSS3, now supports a new feature that allows you to added rounded corners to elements in your HTML. Rounded corners suddenly have never been so easy.

The iPhone was a relatively open phone and we accepted it, but the iPad is a relatively closed computer designed to be a controlled distribution channel, and that's a bummer. The thing is, Jobs' argument was always a bit disingenuous. Closed follows from his brain architecture, not from an argument on behalf of his customers or their network providers. Those are post facto justifications supporting an already-held point of view. And the reason the iPad is going to stay closed isn't because it is good for users, it's because it is good for Apple.

One of Linux's strengths is its cross-platform nature: you can run it on
x86, x86-64, SPARC, PowerPC, and many other central processing units (CPUs).
This wealth of hardware choices poses a challenge for software developers,
though. Ensuring that software compiles, and runs correctly, on all platforms
can be difficult. The use of the QEMU package can help ease this burden. QEMU
is a machine emulator that supports a wide range of CPUs, so you can run
PowerPC software on an x86 computer, x86-64 software on an SPARC computer, or
what have you. This facility is particularly useful for programmers who need
to test software's endianness compatibility or check other CPU-specific
features. QEMU also enables you to run different operating systems entirely,
so that you can test a program's ability to compile and run under FreeBSD,
Solaris, or even Microsoft Windows without shutting down Linux.

With the increasing interest in Ruby on Rails from companies in the
enterprise world, some observers have posed questions about its suitability
when it comes to the demanding requirements in this arena. One issue that some
have called attention to is that ActiveRecord, Rails' Object-Relational Mapper
(ORM), doesn't use prepared statements--or at least it didn't until now. With
the latest release of DB2 on Rails, parameterized queries are automatically
available and bring with them important performance and security benefits to
Rails applications.

SugarCRM is the world's leading open source Customer Relationship Management
(CRM) software provider, with over 5,000 customers and 500,000 downloads of the
SugarCRM application all around the world. SugarCRM has long had a very useful Web
Services framework, allowing applications to access the SugarCRM instance and work
with data on it. But new to SugarCRM 5.2 is a framework for accessing other
outside Web services from inside the application itself. SugarCRM 5.2 ships with a
LinkedIn connector by default that uses this framework. Thus, users of the
SugarCRM instance can check on the LinkedIn status of various companies, contacts,
and leads they might have. In this article, learn how the connectors framework
works in Sugar 5.2 by building an example connector that allows users to see any recent Google News items pertaining to companies in their SugarCRM instance.

OpenID is a decentralized authentication protocol that makes it easier for users to access resources in your Java Web applications. In this first half of a two-part article, you'll learn about the OpenID Authentication Specification and walk through the steps of incorporating it into a sample Java application. Rather than implement the OpenID Authentication specification by hand, author J. Steven Perry uses the openid4java library and a popular OpenID provider, myOpenID, to create a safe and reliable registration process for a Java application written in Wicket.

Portals provide information from diverse sources in a unified way. When portlets are integrated into a portal, the
functions delivered as part of each portlet should be available all of the
time. Unit testing can ensure that the features of your portlets will work
all the time, and everywhere. It is important to unit test portlets before
they are hosted publicly, and testing with
frameworks will speed up the testing process. In this article, learn about
portletUnit, a
JUnit testing framework for testing JSR-168 portlets. portletUnit uses a mock
container for testing, thereby reducing
the cost of investment in huge portal server environments. With the portletUnit framework
you can run unit tests
on any machine--without a portal server.

Apache Wink is fast becoming one of the de facto implementations of the
JAX-RS 1.0 specification. The providers included with the standard Apache
Wink distribution for JSON
marshalling and unmarshalling, such as JSON.org and Jettison, have some
problems with array representation and limited return types. Coding JAX-RS
services and their client Asynchronous JavaScript and XML (Ajax) applications can be difficult.
In this article, learn a method for configuring an existing Apache
Wink-enabled Web application to use the Jackson JSON provider to solve
some of the problems. An example, with sample code for a simple
Jackson-enabled JAX-RS Web service, illustrates the advantages of this provider.

ZK, an open source Asynchronous JavaScript + XML (Ajax) framework
written in Java code, lets you write a Web 2.0-enabled, rich Internet
application without writing a single line of JavaScript code. Typical Ajax
frameworks like Dojo have JavaScript libraries that expose certain API's for
making "Ajaxified" calls. ZK, on the other hand, uses a meta-definition based
on XML to define the user interface. Translation to HTML code then occurs when
this page is requested by the client. This article introduces you to ZK and
gives you a real-world example of its use running on Apache Tomcat and
connecting to a MySQL database.
