Instant gratification is quite gratifying. Because I haven't yet perfected the Arduino Wetwired Electronic Semi-Omniscient Memory Enhancer (A.W.E.S.O.M.E. for short), we figured the best way to serve our fast-paced world was to have a Web Development issue. Let's face it, if you want to see the weather forecast, you visit a weather Web site. Waiting for the six o'clock news takes too long, and I'm not willing to admit I'm old enough to watch The Weather Channel. The Web, along with its Twitter-esque companions, is currently the fastest way to get information to the masses. And we want to help.
Reuven M. Lerner starts things off with the back end of the Internet. No, I don't mean my personal Web site; I mean databases. This month, Reuven looks at PostgreSQL 9.0. Even if you're a MySQL fan, PostgreSQL is hard to hate, and Reuven explains why. Dave Taylor is hard to hate as well, and this month, he takes us back to our youth with the second part of his series on creating Mad Libs. I did my first Mad Lib when I was [ANY_NUMBER] years old, while I was [ACTIVE_VERB] in [PLACE], and it was really [DESCRIPTIVE_ADJECTIVE].
Kyle Rankin and Mick Bauer teach us about servers this time around. Kyle describes creating a DNS server as part of his series “Building Your Own Personal Server”. DNS can be complicated, but Kyle walks through setting up the industry standard, BIND. Mick is on the opposite end of the spectrum with his “Interview with a Ninja”. What Kyle shows how to build, Mick and his ninja talk about hacking into—good information from both guys.
We've all been 37 steps into an on-line form, only to have a click of the Back button completely ruin the form on which we worked so hard. Creating desktop-like Web apps is popular, but sometimes the sites we visit don't work the way we expect. We want the Back button to take us back a page, but with Web programming, that's not always as easy as it sounds. Avi Deitcher addresses the problem and explains how to make AJAX applications honor the venerable Back button. Avi also shows why JavaScript itself is so awesome in another article, “Simplicity and Performance: JavaScript on the Server”. Go get a cup of java, and check out his JavaScript articles. You'll be a better programmer for it.
Some of us aren't hard-core programmers, but we still need to get information onto the Web and have it look good and perform well. That's when content management systems are awesome. Michael Connors introduces Zotonic, a content management system based on Erlang. If you're new to the idea of a CMS, you'll want to check out Zotonic, which is a CMS, but also a Web framework. Drupal, on the other hand, is a traditional CMS that is used in thousands of Web sites across the planet. Our own LinuxJournal.com Web site runs Drupal, and this month, Webmistress Katherine Druckman interviews Angela Byron, the co-maintainer of Drupal 7. Reading the interview will teach you a bit about Drupal, but even more than that, it will give you a behind-the-scenes glimpse at managing a large open-source project. Drupal 7 sounds like a huge step forward in usability, and it's Angela's job to make sure that step doesn't trip and fall along the way.
I know some of you are annoyed by the Web and its dependence on mouse clicking. I suspect Kyle Rankin and his terminal window are as well. James Walker feels the same way and introduces Drush, a command-line interface for Drupal. Sure, a nice GUI is great, but sometimes it's hard to beat a simple command line. James demonstrates a click-free way to interact with Drupal. It's pretty cool for those of us addicted to the command line.
If you're not interested in the Web at all, we haven't forgotten you this month. Whether you want to make a quick user interface with Qt (Johan Thelin shows how) or manage and convert your e-book collection with Calibre (Dan Sawyer explains the process), this issue is bound to please. We also have a review of D-Link's Boxee Box by yours truly, and we have instructions on how to find yourself—with Google Maps (Mike Diehl shows how to manipulate the API).
This is a very fun issue, and until my A.W.E.S.O.M.E. is fully developed, turning the page and reading is the best way to assimilate the information. I'm not sure whether my Arduino brain implant will be ready for the Cool Projects issue, but those interested in beta testing should feel free to contact me. Just think real hard and the message should get to me, assuming my A.W.E.S.O.M.E. is working correctly. Until then, have a [DESCRIPTIVE_ADJECTIVE] [TIME_PERIOD], and we'll [ACTION_VERB] you next month!

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.

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6
Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.

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?
