AJAX Lowers Yahoo! Page Views, Eric Miraglia Explains Why That's Good

Eric Miraglia To Present at the AJAXWorld Conference & Expo, September 23-26 in Santa Clara

We're all familiar with the names: YUI, Prototype, Dojo, JQuery, MochiKit, Tibco, Backbase, and many more. Some are free; some aren't. Some are well documented; many more aren't documented at all. Some support all the browsers you care about; some don't. Some are accessible and work well with assistive technologies; many don't. Some are spry and fast; some are heavy and slow.

What all the prominent JavaScript libraries have in common is that they promise to save you time in building rich internet applications by offloading some of the heavy lifting that characterizes development in the browser. However, libraries on the client-side of the browser-server divide are different than libraries in other software development environments. Client-side libraries are transmitted to the client with each page, loaded and processed with each page, and their ability to render UI is throttled by a slow, inconsistent DOM API that is wildly suboptimal when it comes to performance.

We pay a big price as developers for the benefits we gain from deploying our apps instantly and ubiquitously on the web. JavaScript libraries don't change that fundamental paradigm...at best, they make the paradigm a little less idiosyncratic. But that normalization, too, comes at a price. Choosing a frontend library for JavaScript and CSS has become a key decision point early in the lifecycle of web development projects. Choosing when to use the library and when to build custom code and widgets has become an important decision point later in the process.

In this session, we'll look at how best to assess the value proposition of libraries with respect to specific projects and how to make good long-term decisions about how those libraries should be deployed. You'll leave this session with a better idea of how libraries work both for and against you and what the intrinsic compromises are when using library code versus "roll-your-own" solutions.



Speaker Bio: Eric Miraglia has been authoring social web applications since 1995, when he began developing interactive writing spaces for universities; his Speakeasy Studio & Cafe as used by more than 100 universities between 1997 and 2004. Since 2003, Eric has been a part of Yahoo's web development community. In 2005, he joined the newly formed YUI team where he serves as an engineering manager. In a few short years, YUI has come to underpin some of the most trafficked websites in the world, including among many others Yahoo's front page, Yahoo Mail, My Yahoo, and Yahoo Finance properties. Eric has led the effort to make YUI the best-documented open-source JavaScript library and founded the YUI Theater to help provide worldwide access to many of the great events and speakers who come to Yahoo from around the world of web development.


Eric Miraglia's last AJAXWorld presentation was streamed by more than
100,000 SYS-CON.TV viewers

The world’s leading Rich Internet Applications & Web 2.0 event is expected to attract more than 1,000 i-technology developers. AJAXWorld grew from a single track, one-day seminar, less than a year ago, into a four-day international conference & expo with more than 150 sessions delivered in ten simultaneous tracks, by more than 150 faculty members.

Track 01: Rich Internet Applications
Track 02: Web 2.0 Enterprise Mashups

IoT & Smart Cities Stories
As IoT continues to increase momentum, so does the associated risk. Secure Device Lifecycle Management (DLM) is ranked as one of the most important technology areas of IoT. Driving this trend is the realization that secure support for IoT devices provides companies the ability to deliver high-quality, reliable, secure offerings faster, create new revenue streams, and reduce support costs, all while building a competitive advantage in their markets. In this session, we will use customer use cases...
Bill Schmarzo, author of "Big Data: Understanding How Data Powers Big Business" and "Big Data MBA: Driving Business Strategies with Data Science," is responsible for setting the strategy and defining the Big Data service offerings and capabilities for EMC Global Services Big Data Practice. As the CTO for the Big Data Practice, he is responsible for working with organizations to help them identify where and how to start their big data journeys. He's written several white papers, is an avid blogge...
When talking IoT we often focus on the devices, the sensors, the hardware itself. The new smart appliances, the new smart or self-driving cars (which are amalgamations of many ‘things'). When we are looking at the world of IoT, we should take a step back, look at the big picture. What value are these devices providing. IoT is not about the devices, its about the data consumed and generated. The devices are tools, mechanisms, conduits. This paper discusses the considerations when dealing with the...
Business professionals no longer wonder if they'll migrate to the cloud; it's now a matter of when. The cloud environment has proved to be a major force in transitioning to an agile business model that enables quick decisions and fast implementation that solidify customer relationships. And when the cloud is combined with the power of cognitive computing, it drives innovation and transformation that achieves astounding competitive advantage.

In this blog post, we provide 7 tips on how, as part of our world-class faculty, you can deliver one of the most popular sessions at our events. But before reading...
If a machine can invent, does this mean the end of the patent system as we know it? The patent system, both in the US and Europe, allows companies to protect their inventions and helps foster innovation. However, Artificial Intelligence (AI) could be set to disrupt the patent system as we know it. This talk will examine how AI may change the patent landscape in the years to come. Furthermore, ways in which companies can best protect their AI related inventions will be examined from both a US and...
Poor data quality and analytics drive down business value. In fact, Gartner estimated that the average financial impact of poor data quality on organizations is $9.7 million per year. But bad data is much more than a cost center. By eroding trust in information, analytics and the business decisions based on these, it is a serious impediment to digital transformation.
Digital Transformation: Preparing Cloud & IoT Security for the Age of Artificial Intelligence. As automation and artificial intelligence (AI) power solution development and delivery, many businesses need to build backend cloud capabilities.
