Emergency Telephony (ETel 2007)
27 February–1 March 2007
Technologists, CTOs, chief scientists, researchers, programmers, hackers, business developers, entrepreneurs, and other interested parties are invited to lead conference plenary sessions and workshops at ETel 2007. Topics will center on the innovations and projects occurring in open source telephony, wireless mobility, mobile telephony, Wi-Fi VoIP, telephone networks as platforms, and the intersection of VoIP telephony with Web services.
Open source software and telephony is a special area of focus for this conference. Open source platforms have been created and are being implemented by hackers and businesses alike. But the conference hopes to explore the next evolution, new hardware on the horizon, and improved capabilities. Organizers hope to solicit presenters that can demonstrate tool kits and technologies.
For the VoIP telephony/Web services intersection discussion, organizers seek submissions that explore what the future will look like when, for example, every site allows users to call someone's cell phone, or provides Web-calendar editing by just calling an artificial voice agent. The conference expects presenters and workshops to explore innovation potential and experiment ideas for Web/phone services startups.

Taking the VoIP Plunge
Switching to VoIP, Theodore Wallingford. Many businesses get their phone service through the Internet instead of from local phone companies. Several companies also use their internal local area network and wide area network infrastructure to replace legacy enterprise telephone networks. This migration to a single network carrying voice and data is called convergence, and the technology driving it is voice over IP (VoIP).
The author believes VoIP has advanced Internet-based telephony for a viable solution to business telephone challenges. The primary reason, the author argues, for migrating to VoIP is cost, as it equalizes costs of long distance calls, local calls, and emails to fractions-of-a-penny per use. But the author believes that the real enterprise turn-on is how VoIP lets businesses customize telecom and datacom solutions using a single, cohesive networking platform.
This book provides solutions for the most common VoIP migration challenges. Network professionals who are migrating from a traditional telephony system to a modern, feature-rich network will be interested in this book. Readers can learn the strengths and weaknesses of circuit-switched and packet-switched networks, how VoIP systems affect network infrastructure, as well as solutions for common challenges involved with Internet Protocol (IP) voice migrations. The author explores topics such as building a softPBX, configuring IP phones, ensuring quality of service, scalability, standards-compliance, topological considerations, coordinating a complete system switchover, migrating applications such as voice mail and directory services, retrointerfacing to traditional telephony, supporting mobile users, security and survivability, and dealing with challenges of network address translation.

Speech Quality in VoIP
Speech Quality of VoIP: Assessment and Prediction, Alexander Raake. Set for publication in November, this book serves as a guide to assessing VoIP networks speech quality and addresses VoIP networks and systems design implications. The book explores both the technical network world and the psychoacoustic world of quality perception. The author combines awareness of VoIP-network technical characteristics with original research concerning perceptions of the speech transmitted across them.
Starting from the network designer's point of view, the book first addresses the different network characteristics, and then links to features that users perceive. This book provides an overview of the available knowledge on aspects of speech and speech quality perception, of speech quality assessment, and of telephone and VoIP network transmission properties and their related perceptual features and resulting speech quality. The author discusses new research into the specific time-varying degradations VoIP brings along, including the potential quality improvement from wideband speech transmission.
The book offers insight into speech quality of VoIP from a user's perspective, presents an overview of different modeling approaches, and a parametric network-planning model for quality prediction in VoIP networks. It also discusses research on VoIP's quality degradation characteristic and explains how VoIP's wideband speech transmission capability greatly enhances telephone speech quality. The author also assesses the collection of references on the technical and scientific literature related to VoIP quality and illustrates concepts throughout with mathematical models, algorithms and simulations.

Internet Apps from the Ground Up
Web Programming: Building Internet Applications, Chris Bates. The author of this book believes that Web programming is about more than creating and formatting Web pages and Web sites, though that is often a starting point for many. Using scripting languages such as Java-Script, Perl, and PH, it becomes possible to add a lot more functionality to a site.
Web Developers Notes
The Web Graphics Design section has articles on Web image optimization, Web image usage, image manipulation software and programs, and graphics editors. The articles in this section have been broadly classified into seven categories: Web image basics, GIFs, animated GIFs, JPEGs, Web image usage, favicons, and image editors.
A favicon is a small image that usually acts as a Web site identifier as it's saved with the URL in the Bookmarks/Favorites folder, and is also displayed in the Location Bar and Tabs in Mozilla and Netscape browsers. The favicon section on the site teaches how to create a favicon for a Web site using popular favicon creation programs available on the Web. It also shows how and where to put the favicon online on a Web site.
Many image-editing programs are available in today's market, with large variations in features and price. This section advises assessing an image editor's features to understand if it suits requirements. For example, if work mainly involves photograph touchup, a vector-based image editor will be of little use (if at all), according to this site. This section evaluates graphics tools from Adobe, Corel, Macromedia, Jasc, Ulead, Xara, iPix, and The Gimp.
7–9 November 2006
What began in 2004 as a focused gathering on the implications of the Web becoming a platform has changed into an event that focuses on Internet innovations—its services, applications, businesses, and models.
In 2004,Web 2.0 focused on one idea: The Web had become a platform for potentially new business forms. In 2005, the second annual Web 2.0 Conference focused on highlighting emerging innovations, with a particular emphasis on entertainment, communications, and IT industries.
This year, the focus is on widespread disruptions in the industry's traditional business models. The telcos square off against VoIP and bandwidth-hungry content companies. Entertainment and publishing companies struggle with consumer-driven media and the attention economy. And the IT giants such as Microsoft face the challenge of ad-subsidized free competitors such as Yahoo! and Google.
More than 50 leaders and entrepreneurs are scheduled to present an interactive forma, more than a dozen speakers will present 10-minute stand-and-deliver presentations designed to engage the audience, executives from platform businesses will address the future of the Web in plenary sessions, new Web technologies will be covered in workshops, and the second annual Launch Pad event will feature presentations by start-ups.
Conference topics include Defining Web 3.0: What's Next?; Collision of the Titans: Publishers v. Platforms; Collective Intelligence or the Madness of Crowds?; What Might Go Wrong in Web 2.0?; Is the IPO Culture Over?; Launch Pad 2.0; The Tiered Internet: A Debate; Web 2.0 in China; High Order Bits; Disrupting the Disruptors: Incumbents Strike Back; and Privacy and Trust: Who Owns Your Data?
One of the scheduled speakers is Vinton G. Cerf, a Google vice president. Cerf, known as one of the "Fathers of the Internet," is the codesigner of the TCP/IP protocols and the Internet's architecture.
All the World's an App
.NET Internationalization: The Developer's Guide to Building Global Windows and Web Applications, Guy Smith-Ferrier. As business becomes more global, software developers need to make applications multilingual and culturally aware. The .NET Framework supports internationalization and globalization, and this book teaches developers how to use that support.
The author, an international application developer, covers the internationalization of both Windows Forms and ASP.NET applications, using both versions 1.1 and 2.0 of the .NET Framework. The book teaches how to take advantage of the globalization and internationalization features built into the .NET Framework and Visual Studio and provides original code that takes globalized applications to international utility and maintainability.
The book covers an introduction to the internationalization process and how localization and globalization are supported in Windows and the .NET Framework; also covered are resource managers, cultures, resource data link layers, localized strings, images, and files, including strongly typed resources. The author also covers form localization in Windows Forms and Web Forms, dealing with regional cultures and their casing, collation and calendars, managing right-to-left Middle Eastern text and pictographic, and East Asian languages.
Readers will learn how to use the book's original resource administration utilities, how to translate resources with machine translation, how to create custom cultures and integrate them with the .NET Framework 2.0 and Visual Studio 2005, and how resource managers work. The book also discusses how to write custom resource managers—including a resource manager that uses a database—how to test internationalization with Microsoft's FxCop using new and existing globalization rules, and how to effectively include the translator in the internationalization process.
Developers, architects, and managers will be interested in this book prior to beginning development.

A Standard Web
Designing with Web Standards, Jeffrey Zeldman. Standards, argues the author in this book, are the only hope for breaking out of the endless cycle of testing that plagues designers hoping to support all possible clients. In this book, he explains how designers can best use standards—primarily XHTML and CSS, plus ECMAScript and the standard Document Object Model (DOM)—to increase personal productivity and maximize availability of creations. The author also takes care to explain how features of standards evolved, which will interest professional designers.
Although the author spends time explaining how much easier life would be if browser developers would just support standards properly, he recognizes that browsers implement standards differently and that the Web designer is responsible for maintaining functionality. The book includes tips (with code) that have to do with working on noncompliant browsers, without fouling up more compliant browsers.

Each of these categories has a corresponding folder in the sidebar on the left side of the page. Click around to find the subcategories, which can help narrow down a subject search. The complete list of every subcategory is available to provide a global view of the site. And a Search box is at the top of every page.
The Authoring section breaks down into subcategories including HTML basics, tables, frames, browsers, tools, stylesheets, DHTML, and XML.
XML to the Rescue
XML Problem Design Solution, Mitch Amiano, Conrad D'Cruz, Kay Ethier, and Michael D. Thomas. The authors' approach to learning XML involves walking readers through the process of building a complete, functional, end-to-end XML solution. The book features a case study of an online business product catalog that includes reports, data input/output, workflow, stylesheet formatting, RSS feeds, and integration with external services like Google, eBay, and Amazon.com. Readers will learn how XML markup allows a business to share data across applications internally or with partners or customers, even though they might not use the same applications.
This guide shows the power of XML by presenting an enterprise application problem—throughout the book—that readers will create a program to solve. Each chapter takes one part of the featured project and leads the reader through its solution's design. The authors progress through sections of increasing depth, each one developing a more advanced treatment of XML.
Readers can learn various resolutions to common business and technology needs that are best solved using XML.
