Linux Journal Contents #158, June 2007
This month's issue concentrates on languages, even to the point of metaprogramming concepts where you write programs that write programs! PHP programmers will appreciate some help on how best to validate email addresses. Sun's Simon Phipps explains the move to GPL Java, and defends Sun's motives for protecting Java from corruption as long as was necessary. We'll teach you how to access databases asynchronously from Qt 4.x, which is a big improvement over default Qt 4.x database handling.
As always, there's much more. We'll take a look at the compact but powerful lua, a language so flexible even Blizzard uses it to allow players to extend World of Warcraft. And Christof Wittig is back with Ted Neward to explain the impedence mismatch between object-oriented languages and relational databases.

Free Webinar: Hadoop
How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.
Some of key questions to be discussed are:
- What is the “typical” Hadoop cluster and what should be installed on the different machine types?
- Why should you consider the typical workload patterns when making your hardware decisions?
- Are all microservers created equal for Hadoop deployments?
- How do I plan for expansion if I require more compute, memory, storage or networking?
