|Commodity machine clusters can provide a scalable and highly available platform to deploy Web application and Web services. The networking software required for such clusters, however, is often custom to the specific application and can be daunting to write and test. This article shares how JavaGroups, an open source distributed systems toolkit, can help by providing ready-to-deploy, high-level features such as: group membership management, multicast and unicast message-based group communications, state transfer protocol, functional distributed data structure, and a library of reusable, frequently used communication coding patterns.|

|Linux Access in State and Local Government|
|Linux Journal tells us about
Linux in State and Local Government.
"If one wants to find information about Linux in schools, a search engine would take you to cyber foundries such as SchoolForge. Once there, you would find the information, tools and materials necessary to forge or make a school and all its parts. If such sites existed for government, we could see more tangible progress and empirical evidence of success for the entire Open Source community. "

|Analysis: Open Source Databases|
|LinuxWorld.com.au tells us about
open source databases.
"The consensus with open source databases seems to be one of initial investment and support. If your enterprise is prepared to adopt the in-house support requirements of an open source database, then the free open source databases can save you from purchasing a commercial one. However, if your requirements involve high levels of support, a commercial database may be the most suitable option. "

|Grid Computing: What are the Key Components?|
|Grid computing is gaining a lot of attention within the IT industry. Although it has been used within the academic and scientific community for some time, standards, enabling technologies, toolkits, and products are becoming available that allow businesses to use and reap the advantages of Grid computing. As with many emerging technologies, you will find almost as many definitions of Grid computing as people you ask. However, one of the most used toolkits for creating and managing a grid environment is the Globus Toolkit. This article provides an overview of the key components that make up a Grid environment, and most of the information and concepts within the context of the Globus Toolkit.|

|Sinbad Hears Linux's Siren Song|
|Wired talks about
Sinbad and Linux.
"Animating Sinbad proved a demanding test of the Linux operating system. DreamWorks animators said that when they first began work on the film four years ago, there was no technology capable of doing exactly what they needed it to do."

|Instant Messaging Clients|
|Unix Review takes a look at
Instant Messaging clients for Linux.
"There was a time when sys admins and others used a little program called talk to send quick messages to one another in real time. It was a means of communication that I will bet is largely unknown to most of the net-connected folk of today."

|Building A Home Network From Scratch|
|Tom's Hardware brings us:
Building A Home Network From Scratch.
"While we don't suggest that Internet connectivity options should outweigh other factors in a home purchase, if high-speed Internet access is important to you, then it is wise to do some basic investigation as to what options are available at your home location. An hour spent on the telephone with local cable and Internet Service Providers (ISPs) may make the difference between satisfaction and regret with a home long after the sale has concluded."

|Network Programming With the Twisted Framework|
|Twisted is an increasingly popular pure-Python framework for programming network services and applications. While there are a large number of loosely coupled modular components within Twisted, a central concept to the framework is the idea of non-blocking asynchronous servers. This article introduces you to this style of programming -- a novel one for developers accustomed to threading or forking servers, but one capable of great efficiency under heavy loads.|

|Interview with Brian Hatch|
|Brian Hatch, the author of Hacking Exposed Linux 2nd edition and the Linux Security: Tips, Tricks, and Hackery Newsletter, addresses at length a dozen Linux and security related questions from Help Net Security. He provides insight into the writing and vulnerability testing process, how Linux' increased market share and corporate acceptance affects security, his feelings about code auditing vs kernel hardening, the conflict between programmers and user education, and of course his opinion on full disclosure. Very enlightening. Read it

|LNX-BBC Review: Bootable Business Card Linux|
|This is a short review of a Linux distribution that a sysadmin can literally carry around in his wallet. Since it runs entirely from the mini CD-ROM it's safe to use on any PC, regardless of operating system.
"The selection of files on LNX-BBC is a cross-section of the smallest and most useful applications and utilities in the free (software) world -- with an emphasis on diagnostic and rescue utilities to be used on systems that can't or won't boot and diagnose themselves. If you work with PC's, and especially if you work with Linux PC's, you need this distribution."

|The Linux Geek Diet|
|Linux World brings us the very silly
The Linux Geek Diet.
"The one problem I have with doing any diet is that I'm a writer and a geek. I try to take hikes, long walks, bike rides, and find other ways to exercise, but I spend an inordinate amount of time on my gluteus maximus writing, programming, and performing other sedentary operations."

|Linux on the Mainframe|
|Unix Review takes a look at the book:
Linux on the Mainframe.
"Hosting open source software on mainframes is one of the areas of computing that most excites me. While intellectually much different, it's akin to programming mobile telephone applications, "presencing", and certain kinds of distributed computations in that it's more clear it's going to pay off big, than in exactly what the details of the winning technology will be."
