Eight from IBM: DNS phone numbers, SoC design, OpenLaszlo, SLP…
Feb 24, 2006 — by LinuxDevices Staff — from the LinuxDevices Archive — viewsIBM has published the following new technical articles, tutorials, and downloads on its DeveloperWorks website. They cover a range of interesting (though not necessarily embedded) technical topics, primarily related to Linux and open source system development. Some require free registration. Enjoy . . . !
- Domain names as mobile phone numbers — Why not take the Domain Name System (DNS), which is used primarily on the Internet, and implement it in mobile phones? Find out what DNS is all about, how mobile phones actually work behind the scenes, and the reasons why a domain name is much better than than an actual cell number. It turns out that its not that crazy an idea after all.
- Shared Resource Management on a SoC — The goal of a system-on-a-chip (SoC) is to provide a single-chip system, and therefore SoC resource analysis and sizing is critical. Failure to properly size processing, memory, or I/O needed by software services can kill an SoC project. But all too often, SoC design analysis focuses on processing at the expense of memory or I/O sizing. Any mis-sizing or mismanagement of memory and I/O on an SoC can at the least cause significant project delay and rework.
- The OpenLaszlo Javascript advantage over normal Flash and Ajax — OpenLaszlo is a rich client application architecture that uses Macromedia to build Flash widgets with XML and JavaScript logic. This article details the basic concepts of OpenLaszlo, and gives examples of situations in which an OpenLaszlo solution might be beneficial and it also details how it compensates for the shortcomings of Ajax dynamic web development.
- Help Network Clients Help Themselves — The Service Location Protocol (SLP) is an Internet Standard RFC and software framework that allows networking applications to discover and configure network services. You can use SLP to develop zero-configuration applications and simplify administration of networked devices. This article introduces SLP and its architecture, and then demonstrates the protocol's use with an open source implementation.
- Explore the New Features of Eclipse V3.1 — This tutorial demonstrates many of the new features found in the most recent release of Eclipse V3.1. You will find this tutorial useful if you're considering upgrading to V3.1 from a previous release, or if you're considering switching to Eclipse from another integrated development environment. It is also useful if you want to revise your code to take advantage of the latest iteration of the Java language, Java 2 Standard Edition V1.5, which adds a number of powerful constructs and conveniences to the Java programming language.
- Facelets fit JSF like a glove — While working on a Java Server Faces (JSF) project recently, I had the pleasure of using Facelets for the first time. What I most liked about Facelets was that it let me create reusable composition components. Being able to take a page (like a JSP) and turn it into a Facelets component has been a real boon to my JSF development ever since. My conclusion? If you're not using Facelets, you're not getting the most you can out of JSF.
- Linux Professional Institute (LPI) exam prep — Here's a series of well written IBM Linux tutorials to help you learn Linux fundamentals and prepare for system administrator certification. The LPI prep tutorials help you prepare for the topics in LPI exam 201 and the topics in LPI exam 202.
- IBM Offering New Book to First 300 Subscribers — The developerWorks Power Architecture team is sending out a complimentary copy of IBM's new book when subscribing to the Power Architecture Newsletter. The book is titled “Irresistible! Markets, Models, and Meta-Value in Consumer Electronics”, by the IBM Institute for Business Value (IBV) and the Electronics Team. Offer is valid to new and existing subscribers, quantities are limited to the first 300 respondents, and offer is valid while supplies last — so do not delay.
