Referring to specific information inside an XML document is a little like finding a needle in a haystack. XPath and XPointer are two closely related languages that play a key role in XML processing by allowing developers to find these needles and manipulate embedded information. By the time you've finished XPath and XPointer, you'll know how to construct a full XPointer (one that uses an XPath location path to address document content) and completely understand both the XPath and XPointer features it uses.
Greasemonkey Hacks is an invaluable compendium 100 ingenious hacks for power users who want to master Greasemonkey, the hot new Firefox extension that allows you to write scripts that alter the web pages you visit. With Greasemonkey, you can create scripts that make a web site more usable, fix rendering bugs that site owners can't be bothered to fix themselves, or add items to a web site's menu bar. You can alter pages so they work better with technologies that speak a web page out loud or convert it to Braille. Greasemonkey gurus can even import, combine, and alter data from different web sites to meet their own specific needs.
Greasemonkey has achieved a cult-like following in its short lifespan, but its uses are just beginning to be explored. Let's say you're shopping on an e-commerce site. You can create a script that will automatically display competitive prices for that particular product from other web sites. The possibilities are limited only by your imagination and your Greasemonkey expertise. Greasemonkey Hacks can't help you with the imagination part, but it can provide the expert hacks-complete with the sample code-you need to turn your brainstorms into reality.

For years, computer users have put up with the bugs, security holes, and viruses on Windows because they had no choice. Until recently, there has never been a good alternative to Windows. But now, Windows users can switch to Linux, the reliable, secure, and spyware free operating system. Linux is easy to use, runs on almost any PC, and enables you to perform all the tasks you can do with Windows. Getting to know Linux has never been easier, because now there's a way to test-drive Linux without changing, installing, or configuring a thing on your computer. It's called Test Driving Linux: From Windows to Linux in 60 Seconds. This latest release from O'Reilly comes with a Live CD called Move, that allows Windows users to try all the features of Mandrake Linux, a popular Linux distribution without the hassle of actually installing Linux. Users simply place the Move CD into their CD drive, boot from the disc, then watch an entire Mandrake system run on the fly from the CD-ROM. Test Driving Linux: From Windows to Linux in 60 Seconds is a detailed step-by-step guide to the Linux operating system and several popular open source programs. With this guide you can quickly learn how to use Linux to perform the tasks you do most: surf the web, send and receive email, instant message with friends, write letters, create spreadsheets, and even how to enhance your digital photos. Test Driving Linux: From Windows to Linux in 60 Seconds provides both home and business users with a hassle-free way to investigate this operating system before they purchase and install a complete Linux distribution.
The latest in O'Reilly's line of bestselling Linux titles, Linux in a Windows World is an invaluable companion for any system administrator interested in integrating Linux into their Windows environment. This book takes an in-depth look at exactly how Linux can be brought into an organization that's currently based on Microsoft Windows systems. Featuring a litany of insider tips and techniques, Linux in a Windows World dispenses all the practical advice you need to migrate to this revolutionary open source software.
This project is based on my original contribution to Beautiful Security. In Beautiful Trade: Rethinking Ecommerce Security, I laid out a design for card not present security and the prevention of credit card theft for online merchants and service providers.
I would like to open up this proposed design to the larger community via the commons wiki. The goal of the project is to design an electronic payment system that:
- Is secure by design, without reliance on additional controls outside the payment system
- Does not require major additions to current systems of payment processors or merchants
- Does not require major additions to clients or mass deployments of new software or hardware
- Is easy for consumers to use
When C++ faded into relative obscurity, many of my best friends got burned, badly. They didn't recognize that change was in the air, or how violently change could come. Though I have a whole lot to lose, I'm writing this book because I don't want to see it happen again. If you don't want to be caught by surprise, you need to read this book.
If you think I'm right, you can start to build your skills accordingly. You might download some of the frameworks I discuss, and learn a few new languages. This book will teach you what a new language needs to succeed. If I've gotten lucky and found one of the likely winners, you'll be just a little bit more prepared when things do change.
If you think I am wrong, you can use the best techniques from the best frameworks written in any language to improve what you're doing in Java today. New frameworks like PHP, C Omega for .NET, and Ruby on Rails will come occasionally. You need to know about them, and understand how to evaluate them.
Either way, you win. It's time to start paying attention again. It's time to look to the horizon, beyond Java.
TEST When Beta 1 of Visual Basic .NET hit the programming scene in 2001, the new tool challenged experienced Visual Basic developers to step up to an entirely new programming platform and a whole new way of writing code. Fortunately, four years later, it's clear that the rewards of moving to .NET make up for the steep learning curve developers experience when they try to do so. Developers who have made the jump have a powerful set of tools for building Windows and web applications—a set that other programming frameworks are hard-pressed to match.
Visual Basic 2005 and the platform it's built on, .NET 2.0, don't represent the same seismic change. Instead, Visual Basic 2005 and .NET 2.0 are the latest releases of what are now a mature language and platform. Microsoft architects have ironed out inconsistencies, corrected flaws, and added dozens of requested features, from VB 6's edit-and-continue debugger to new Windows and web controls for displaying data. Still, even the keenest developer could use a quick tour of Visual Basic 2005 and .NET 2.0 to come to terms with all the changes.
This book provides a series of hands-on labs that take you through the new features you'll find in Visual Basic 2005, the .NET Framework 2.0, and the Visual Studio 2005 development tool. Visual Basic 2005: A Developer's Notebook is perfect for developers who have worked with a previous version of .NET and need to quickly get up to speed with what's new. Best of all, you'll learn everything through concise, focused examples (all of which are just a short download away).
Open Sources 2.0 is a collection of insightful and thought-provoking essays from today's technology leaders that continues painting the evolutionary picture that developed in the 1999 book Open Sources: Voices from the Revolution .
These essays explore open source's impact on the software industry and reveal how open source concepts are infiltrating other areas of commerce and society. The essays appeal to a broad audience: the software developer will find thoughtful reflections on practices and methodology from leading open source developers like Jeremy Allison and Ben Laurie, while the business executive will find analyses of business strategies from the likes of Sleepycat co-founder and CEO Michael Olson and Open Source Business Conference founder Matt Asay.
The World Economic Forum started a research project at Davos 2009 concerning cloud computing, which they broadly define to include all kinds of remote services, from Software as a Service to virtual machines.
Andy Oram was asked to provide some ideas on the implications of cloud computing for business as well as its future operating environment. This wiki is a discussion forum where anyone with relevant and valid ideas can suggest points for ongoing research into the social and economic issues (as well as relevant technical issues).
Cloud computing is a huge topic, of course, spawning whole fields of study (as well as a lot of hype). This wiki tries to focus on long-term social and economic effects, especially on a global basis.
