Its a good thing to learn how to download and display images with J2ME (Java 2 Micro Edition) and the Mobile Information Device Profile (MIDP). Bring images to your PDAs through simple J2ME and MIDP development. In this tutorial, J2ME expert John Muchow directs you in building two network-ready apps.
A good example of using a probability model to solove a serious problem is the SpamBayes filtering engine, which uses machine learning and Bayesian inference techniques to compute the probability that a given piece of e-mail is spam. This article demonstrates how to develop univariate probability models in PHP; discusses how to fit empirical data distributions to a theoretical probability distribution; and showcases an important tool for all this -- the Probability Distributions Library (PDL).
This is worth checking into. The Darwin Information Typing Architecture (DITA) is an XML-based format for structuring and authoring technical content. This article explores advantages DITA provides for producing HTML content -- including easy global changes, portability through standards, superior linking and Web management, conditional processing, content and design reuse, and better writing through focused content.
Easy Mining Procedures for DB2 Intelligent Miner provide an easy-to-use SQL interface for the main steps of the data-mining process. In particular, they contain stored procedures for the basic mining functions such as classification, clustering, or discovery of association rules and procedures for general, "higher-level" mining concepts such as the discovery of a prediction model or the detection of outliers in a table. Easy Mining Procedures for DB2 Intelligent Miner are implemented as Java stored procedures of DB2. They exploit the functionality of Intelligent Miner Modeling and Scoring. In general, one call to an Easy Mining procedure corresponds to the execution of several SQL statements with the functions and methods of Intelligent Miner Modeling and Scoring.
This article provides a step-by-step description of how to build a single sign-on solution(SSO) for a Web portal. It shows you how to use the open source solution CAS, the Central Authentication Service from Yale University. CAS is an easy way to integrate an open source, Java-based authentication for SSO
USB, secure shell, and file sharing -- the last of four tutorials designed to prepare you for the Linux Professional Institute's 102 exam. This tutorial introduces you to the ins and outs of using USB devices, how to use the secure shell (ssh) and related tools, and how to use and configure Network File System (NFS) version 3 servers and clients. This tutorial is ideal for those who want to learn about or improve their foundational Linux USB, networking, and file sharing skills.
This article shows how to develop a plug-in that embeds the HSQLDB pure-Java relational database server into the Eclipse Workbench. Although not as powerful as DB2 and not as popular as MySQL, HSQLDB (the hypersonic SQL database) can satisfy the needs of a wide range of Java applications, because of its extensibility and low memory/processor requirements.
URI Access for DB2 is a servlet that uses several access methods to addresses and retrieves data and metadata stored in DB2. It uses Uniform Resource Identifiers (URIs) provided by clients, thereby enabling easy access to one or more DB2 instances through Web browsers and other clients that use the supported protocols. Currently, URI Access for DB2 supports only HTTP.
This tutorial is the first part of a series that introduces you to Web services concepts and technology, demonstrates how to practically apply these concepts using the IBM WebSphere SDK for Web services V5.1 (WSDK), and how to use Eclipse to create Web services using WSDK-supplied plug-ins.
The impending release of a new stable kernel promises greater adoption for Linux, as it becomes more reliable and scalable over a larger variety of processors. This is a new article that highlights some of the changes, both big and small, with some code samples.
LITTLEWHITEDOG has posted a new guide, outlining in great detail How to install and Secure a BSD system.
This article shows you how to improve the boot speed of your Linux system without compromising usability. Essentially, the technique involves understanding system services and their dependencies, and having them start up in parallel, rather than sequentially, when possible.

Here are a couple of tutorials that shows developers how to use KParts components in a KDE application. In Creating Kparts componets Part 1 you will get an intro to the core KParts concepts of read-only and read-write parts and network transparency. You'll learn how to create a read-only component, and then modify it to be a read-write component. You'll also learn how to deploy the component so that Konqueror can use it.
In Part 2 you will learn how to use the KDE Trader to locate the appropriate component, how to handle user interface merging, and how to embed multiple parts in the same window with the help of the Part Manager.

Manageability Services for Linux are grid services that provide manageability functions for system resources. (Globus Toolkit 3.0 is included.) These services take advantage of self-describing and on-demand features of grid services to control resources in autonomic and/or grid environments. Manageability Services for Linux is a prototype for such a manageability framework for managing Linux resources. This prototype consists of a Sametime messaging service for notifying users of critical changes, and a collection of manageability services for some of the most commonly used resources, including Linux OS, Linux processes, disk partitions, system statistics, and system services.
Linux and USB flash drives two great tastes that taste great together. Too bad most distros don't support them by default Here's how to get them to play nice.
