The Jabberwocky IDE for LISP

The first beta release of the new Jabberwocky integrated development environment for LISP has been announced. Jabberwocky supports CLISP versions 2.27 and 2.28 and CMUCL versions 18c and 18d. Support for SBCL and GCL is planned. Jabberwocky works under Linux 2.4 and Windows, and has been released under the GNU GPL.

Jabberwocky's list of features include:

• A lisp-aware editor with syntax coloring and code completion.
• An interaction pane for display of the LISP process.
• A browser for viewing source code, functions, and macros.
• A source level debugger.

For more information on Jabberwocky, see the following documentation:

• User Guide
• Reference Manual Under Construction
• Extending Jabberwocky
• Installation Guide Scroll Down for Linux
• Downloads

As time marches on, the list of IDEs for Linux continues to grow, Jabberwocky looks to be a useful addition to the Lisp developer's toolbox.

Thanks to author Marc Mertens.

Connecting middleware to Apache 2.0 (IBM developerWorks)

Uche Ogbuji introduces Apache 2.0 filter modules on IBM's developerWorks. "Apache became the most popular Web server in part because of the rich availability of third-party extensions for the server, and because its open architecture made it quite easy to roll your own extensions. Of course, nothing is ever just easy enough, so in developing Apache 2.0, one of the main goals was to improve the Apache API to make it even easier to develop extensions."

Open source satellite control (IBM developerWorks)

Cameron Laird writes about a multi-language satellite control system at JPL. "How do you harness a satellite control system written in three languages, on four development platforms, and deployed to multiple client environments? With open source, naturally. When one wrong move can cost millions, rely on teamwork, smart design, and open standards to keep the project -- if not the satellite -- from going down in flames."

Introducing Nonblocking Sockets (O'Reilly)

Giuseppe Naccarato illustrates the use of nonblocking sockets in Java 2 Standard Edition 1.4. "As of Java 1.4, a programmer can use a brand-new set of APIs for I/O operations. This is the result of JSR 51, which started in January 2000 and has been available to programmers since Java 1.4 beta. Some of the most important new features in Java 1.4 deal with subjects such as high performance read/write operations on both files and sockets, regular expressions, decoding/encoding character sets, in-memory mapping, and locking files. In this article, I will discuss one particular new concept -- the new I/O API: nonblocking sockets."

EJB Inheritance, Part 1 (O'Reilly)

Emmanuel Proulx discusses EJB inheritance in part 1 of a series on O'Reilly. "Entity beans are objects that represent data coming from a persistent store, such as a database. The key word here is objects. Entity beans encapsulate the data and business logic. But what about the two other principles, inheritance and polymorphism? The bad news is that entity beans do not easily enable the use of these principles. The good news is that if you follow certain restrictions and tricks, it can be done. This series of articles describes some techniques to put inheritance and polymorphism back into entity beans."

Introducing Smarty: A PHP Template Engine (O'Reilly)

Joao Prado Maia introduces Smarty on O'Reilly's OnLamp site. "Smarty is a somewhat new development in the PHP world, and it brings several new and unique features. One of these unique features is that Smarty 'compiles' the parsed templates into PHP scripts, and then reuses the compiled template when appropriate. Obviously, this brings a huge performance improvement over other template solutions, as the main PHP script doesn't need to parse and output the same template on every request."

Get ready for XForms (IBM developerWorks)

Joel Rivera and Len Taing introduce XForms on IBM's developerWorks. "Traditional HTML forms violate many of the tenets of good markup language design, frequently mixing presentation and data. In this article, Joel Rivera and Len Taing introduce you to XForms, an extension of XHTML that represents the next generation of Web forms. Though XForms is still in an embryonic state, it holds great promise: For instance, a form written with XForms can be written once and displayed in optimal ways on several different platforms."

Taking Kylix 3 for a test drive (LinuxWorld)

Joe Barr writes a small application using Kylix 3 Open Edition (K3OE). "This week, I'll be describing my experiences actually using K3OE, particularly its brand-spanking-new C++ IDE. Previous versions of Kylix have been for Delphi only. I know, I know — true Linux geeks never use RAD tools, or even IDEs. Not unless you consider Emacs to be an IDE, that is. For the rest of the world, RADs and IDEs are very handy tools that provide real productivity gains. Management likes that."
