Niklaus Wirth of the Swiss Federal Institute of Technology {ETH] waspresented the 1984 ACM A. M. Ihring Award at the Association’s Annual Conference in San Francisco in October in recognition of his outstanding work in developing a sequence of innovative computer languages: Euler’ ALGOL-W, Modula, and Pascal. Pascal, in particular, has become significant pedagogically and has established a foundation for future research in the areas of computer language, systems, and architecture. The hallmarks of a Wirth language are its simplicity, economy of design, and high-quality engineering, which result in a language whose notation appears to be a natural extension of algorithmic thinking rather than an extraneous formalism.

Create JSF-like components, using JSP tag files
Learn how to use deferred values and deferred methods in custom JSP tag

JavaServer Pages (JSP) and JavaServer Faces (JSF) used to have different variants of the Expression Language (EL). Their unification in JSP 2.1 opened new possibilities, allowing you to use deferred values and deferred method attributes in your custom JSP tags. This article shows how to develop Java™ Web components based on JSP tag files, which are much simpler and easier to build than the JSF components.

The simplest definition of RSS is an eXtensible Markup Language(XML) format that uses the Resource Description Framework (RDF) for representing information about resources on the World Wide Web. Similarly, Atom is another format based on XML technology.
