A power-user's guide to multilingual editors
Find out how Unicode-encoded character sets make multilingual editing possible, and the way in which existing Unicode editors running on Linux use those facilities. Unicode editors, such as Yudit and Mined, are designed to enable multilingual editing using Unicode-encoded character sets. The architecture required to get them to work is complex and requires a subtly configured web of libraries, particularly if a Unicode editor is to rely on Linux and UNIX system library resources instead of providing its own character and string management machinery.

A step-by-step guide to publishing your own PEAR channels
The PHP Extension and Application Repository (PEAR) is a collection of PHP packages built to ease the development required to build an application. V1.4 of the PEAR package manager introduced the concept of channels, which are a way to organize and deliver packages that can be installed with the package manager. This tutorial discusses channels, introduces and explains the channel.xml file, and demonstrates how to build a channel for distributing packages. Channels are ordinarily used to expose PEAR packages through the Internet, but enterprises can uses channels to make distribution of enterprise-specific PHP code easy.

Interfacing with the CDT debugger, Part 2: Accessing gdb with the Eclipse CDT and MI
The graphical debugging environment provided by the Eclipse C/C++ Development
Tooling (CDT) is about as good as it gets, displaying breakpoints, watchpoints,
variables, registers, disassembly, signals, and memory contents. You can add new
capabilities to this environment or access these views to display output from a custom
debugger. But first, you need to understand the C/C++ Debugger Interface (CDI) and how
it communicates with Eclipse. Part 1 describes the CDI at a high level, and this
article presents a practical example: How the CDT uses the CDI and the Machine
Interface (MI) to interface the GNU Debugger.

PHP frameworks, Part 4: Ajax support
A common criticism of early versions on PHP was that they did not support
Model-View-Controller (MVC)-style architectures. Today, developers can chose from many
PHP frameworks. This "PHP frameworks" series takes a look at three widely used PHP frameworks -- Zend,
symfony, and CakePHP -- examining their similarities and differences while
building and extending a sample application in each of the three frameworks. Part 1
lays out the scope for the series and gets the prerequisites out of the way. In Part
2, you build the sample application in each of the three frameworks. In Part 3,
you extend the application and look at exceptions to the rule. Here,
take a look at how Asynchronous JavaScript + XML (Ajax) is supported in each of the frameworks.

An introduction to SQLite, an open source embeddable database
Databases have been an integral part of software applications since the dawn of the commercial application market several decades ago. As crucial as database management systems are, they also come with a large footprint, and considerable overhead in system resources and administration complexity. As software applications become less monolithic and more modular, a new type of database can be a better fit than the larger and more complex traditional database management systems. Embeddable databases run directly in the application process, offer zero-configuration run modes, and have very small footprints. This article introduces the popular SQLite database engine and describes how to use it in application development.

An introduction to Service Data Objects for PHP
Service Data Objects (SDOs) have been around in the Java technology world since November 2003. They are designed as a means of simplifying and unifying working with heterogeneous data sources. In February 2005, IBM and Zend announced a strategic partnership to collaborate on the development and support of the PHP environment. One aspect of this collaboration has been the definition and implementation of SDOs for PHP. This article gives an overview of SDOs and the motivations for using them in the PHP environment. A simple contact management scenario is used to illustrate key concepts.

An introduction to neural networks
Neural nets may be the future of computing. A good way to understand them is with a puzzle that neural nets can be used to solve. Suppose that you are given 500 characters of code that you know to be C, C++, Java, or Python. Now, construct a program that identifies the code's language. One solution is to construct a neural net that learns to identify these languages. This article discusses the basic features of neural nets and approaches to constructing them so you can apply them in your own coding.

All Hail Shale: Anatomy of a Shale application
Brett McLaughlin continues his introduction to Shale with an in-depth look at the framework's application directory structure. Using the Shale starter application introduced in the first article in this series, Brett walks you through the core directories, from src/ to dist/. He shows you how Shale stores its libraries, where custom files go, and where you can insert specialized behaviors into your Shale applications. Along the way, he gives you some important tips about managing the Shale directories and gets you started with an example application (based on the Shale starter application) that serves as the basis of his discussion for the remainder of the series.

Anatomy of the Linux SCSI subsystem
The Small Computer Systems Interface (SCSI) is a collection of standards
that define the interface and protocols for communicating with a large number of
devices (predominantly storage related). Linux provides a SCSI subsystem to permit
communication with these devices. Linux is a great example of a layered architecture
that joins high-level drivers, such as disk or CD-ROM drivers, to a physical
interface such as Fibre Channel or Serial Attached SCSI (SAS). This article
introduces you to the Linux SCSI subsystem and discusses where this subsystem is
going in the future.

Apache Geronimo on Grails
Do you want to build your Web sites faster and cheaper, but still leverage
industrial-strength technology? You can do just that using Grails and Apache Geronimo.
Grails leverages the power of the dynamic language Groovy to accelerate your
development. However, it runs on the Java Virtual Machine and leverages proven Java
technologies. This makes it easy to take your Grails application to the next level by
deploying it to Apache Geronimo, the premiere open source Java EE V5-certified
application server. In this article, you will see how easy Grails can make Web
development and how easy Geronimo can make Grails deployment. You will also see how a
Grails application can leverage the resources and services provided by Geronimo.

Architecting intrusion-detection solutions
Intrusion-detection systems (IDSs) have become an increasingly important part of the
security strategy of many organizations. An IDS plays a key role in the concept of
defense-in-depth, being only one of several deployed countermeasures designed to deter,
slow down, and detect an attack before it occurs or before more serious actions occur.
Discover the different types of IDSs and what types of attacks each can detect (or not
detect), and see issues to consider when planning an IDS deployment.

Building an Arduino-based laser game, Part 1: Arduino basics
Arduino is an inexpensive, easy-to-use electronics platform. The entire platform, both the hardware and the software, is completely open source, and the language is loosely based on C/C++. Arduino was built for makers, tinkerers, and artists who want to take the plunge into creating interactive physical objects. This three-part series starts with basic Arduino hardware and uses it to create an interactive laser game called "'Duino tag," where players can play tag using devices built nearly from scratch. Here in Part 1 of this "Building an Arduino-based laser game", we craft basic experiments that prepare us for and are a part of 'Duino tag.

Automate Perl module deployment
If you run Perl across many different computers of any sort, you know how frustrating it can be to install Perl extension modules across those machines. The administrative process is even worse if you have a Web server farm and need to keep each machine up to date with a set suite of extension modules for your installation. CPAN helps, but there are issues with CPAN that make it an unwieldy solution for use on a network. This article provides possible solutions before covering the final system. The main goals are a unified installation/module set, a single download, and a guaranteed unified set of version numbers across all the computers in the network.
