To get the most from Google, you need to understand Google. Building Research Tools With Google For Dummies explains how Google works and how you can build more effective queries (hint: it’s a lot more than just using the “Advanced Search” techniques!) It even shows you how to think like a researcher and how to package the results of your research so it means something to your audience. You’ll be able to:

• Understand Google research techniques and use the custom search-related syntax
• Recognize Google’s strengths—and limitations
• Target your search by using Google operators
• Use Google to research photos, or even an entire industry
• Improve the effectiveness of your results by understanding Google’s comparative methodology
• Build custom tools using WDSL and Web Services

This concise handbook targeted at Linux administrators and virtualization enthusiasts is ideal for professionals wanting an easy-to-navigate reference when working with Xen and virtualization. It offers bite-sized practical walkthroughs and experiential solutions for many common virtualization tasks using Xen. Using Fedora Core as host operating system, it shows how to add Xen support and create guest domains running different operating systems, then dissects a range of common virtualization tasks. Originally developed in 2003 at the University of Cambridge Computer Laboratory, Xen is an open-source paravirtualization technology allowing multiple operating systems to run on one physical hardware resource with near native performance. Xen supports several operating systems-Linux, FreeBSD, Windows, and NetBSD. There are now commercial versions of Xen that build on of the open-source version with additional enterprise features; this book explores and uses the open-source version of Xen.

Google is not only the search engine of choice for millions of users, it is an immensely powerful tool for savvy businesspeople who know how to use its advanced features. Go Google is a comprehensive guide to everything readers need to know about Google’s myriad applications, including Google Apps, Google Docs and Spreadsheets, Google SMS, Google Base, and other services that will help businesses get organized — and get noticed.

Software developers make their programs ever more graphical; interfaces become ever more slick. But underneath the buttons and sliders, PCs are electronic systems comprising power supplies, logic processors, and specialized circuitry for such functions as video and sound. When the machine grinds to a halt, someone has to know how to identify the problem and get it straightened out. That's the function of the CompTIA A+ certification, and this new edition of Mike Meyers' A+ Certification Passport will help you earn it. Meyers combines reams of detailed information about IBM-standard PCs (which is to say, those running Intel, AMD, and Cyrix) with rock-solid troubleshooting advice. Look here for electronic details of the IDE and SCSI interfaces, as well as strategies for figuring out whether a problem is in a drive or in its controlling electronics.

Meyers has organized his book around the two A+ exams, which means you'll find excellent coverage of the subjects CompTIA includes (hardware from early days through the Pentium III era, and Microsoft MS-DOS and Windows operating systems through Windows 2000). Inversely, you'll find no coverage of potentially useful subjects that CompTIA doesn't test (Linux and Microsoft Windows XP, most notably). Updated coverage–of new USB and FireWire standards, as well as memory specifications–meets the high standard of the previous edition. This book will help you prepare for the A+ exams; it and a couple of supplementary texts will get you ready for the job site. –David Wall
