Performance-Tune Your AJAX Application

Large applications require more extensive amounts of code, which leads to the inevitable performance bottlenecks

As AJAX matures as a technology, its use in large applications has increased significantly. But large applications require more extensive amounts of code, which leads to the inevitable performance bottlenecks and memory constraints associated with non-trivial application development. This session provides detailed information on how to performance-tune large AJAX applications using a variety of available tools and techniques. Drawing on the experience of having developed large AJAX frameworks, this session will look at a variety of performance bottlenecks that can occur within an application. Special attention will be paid to systematic techniques that yield the biggest return in the shortest amount of time, including: *Using Mozilla's Rhino JavaScript engine as a complete performance-monitoring tool capable of monitoring complete AJAX code bases. *Injecting monitoring code into every function of JavaScript within an application to create a complete performance picture. *Locating performance issues through drilldowns of function call counts, total time spent, average time per call and call stacks. *Start time optimization using Dojo, Gzip, Compression.

Speaker Bio: Bob Buffone, Chief Architect, is responsible for platform and tool technology at Nexaweb Technologies Inc, a provider of the Nexaweb Platform enabling enterprise class rich Internet applications (RIAs). He is also a committer on the Apache XAP Project, which provides an extensible framework for declaratively creating AJAX applications. Before Nexaweb Bob was with Trakus, a technology company focused on tracking sports in real time. A leading expert in User Interface design, he is a regular speaker at industry events and has published multiple articles on tool and application development.
 
AJAXWorld Conference & Expo 2007 West will take place on September 23-26, 2007, at the Santa Clara Convention Center, in Santa Clara, California, and will offer a new dedicated "iPhone Track."
 
Another dedicated track will offer a comparative education opportunity for conference delegates on emerging RIA tools, including a dimaond track on OpenLaszlo, and  sessions on Microsoft's Silverlight, and Sun's JavaFX.
 
 
The world’s leading Rich Internet Applications & Web 2.0 event is expected to attract more than 2,000 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
Track 03: Enterprise AJAX Applications
Track 04: RIA Frameworks & Toolkits
Track 05: Security in RIA Applications
Track 06: Server-Side AJAX
Track 07: iPhone AJAX Applications
Track 08: Silverlight – Flex – Java FX
Track 09: Bleeding-Edge AJAX Applications
Track 10: OpenLaszlo Diamond Track
 
The conference now includes the world famous AJAXWorld University's AJAX Developer Bootcamp, OpenLaszlo Track and Adobe Flex 3 Developer Bootcamp. This year’s AJAXWorld Expo Floor is expected to display bleeding edge RIA technologies from more than 75 leading AJAX vendors.

IoT & Smart Cities Stories
The hierarchical architecture that distributes "compute" within the network specially at the edge can enable new services by harnessing emerging technologies. But Edge-Compute comes at increased cost that needs to be managed and potentially augmented by creative architecture solutions as there will always a catching-up with the capacity demands. Processing power in smartphones has enhanced YoY and there is increasingly spare compute capacity that can be potentially pooled. Uber has successfully ...
Cloud computing delivers on-demand resources that provide businesses with flexibility and cost-savings. The challenge in moving workloads to the cloud has been the cost and complexity of ensuring the initial and ongoing security and regulatory (PCI, HIPAA, FFIEC) compliance across private and public clouds. Manual security compliance is slow, prone to human error, and represents over 50% of the cost of managing cloud applications. Determining how to automate cloud security compliance is critical...
Enterprises have taken advantage of IoT to achieve important revenue and cost advantages. What is less apparent is how incumbent enterprises operating at scale have, following success with IoT, built analytic, operations management and software development capabilities - ranging from autonomous vehicles to manageable robotics installations. They have embraced these capabilities as if they were Silicon Valley startups.
Disruption, Innovation, Artificial Intelligence and Machine Learning, Leadership and Management hear these words all day every day... lofty goals but how do we make it real? Add to that, that simply put, people don't like change. But what if we could implement and utilize these enterprise tools in a fast and "Non-Disruptive" way, enabling us to glean insights about our business, identify and reduce exposure, risk and liability, and secure business continuity?
The Internet of Things is clearly many things: data collection and analytics, wearables, Smart Grids and Smart Cities, the Industrial Internet, and more. Cool platforms like Arduino, Raspberry Pi, Intel's Galileo and Edison, and a diverse world of sensors are making the IoT a great toy box for developers in all these areas. In this Power Panel at @ThingsExpo, moderated by Conference Chair Roger Strukhoff, panelists discussed what things are the most important, which will have the most profound e...

In today's enterprise, digital transformation represents organizational change even more so than technology change, as customer preferences and behavior drive end-to-end transformation across lines of business as well as IT. To capitalize on the ubiquitous disruption driving this transformation, companies must be able to innovate at an increasingly rapid pace.
Predicting the future has never been more challenging - not because of the lack of data but because of the flood of ungoverned and risk laden information. Microsoft states that 2.5 exabytes of data are created every day. Expectations and reliance on data are being pushed to the limits, as demands around hybrid options continue to grow.
"MobiDev is a Ukraine-based software development company. We do mobile development, and we're specialists in that. But we do full stack software development for entrepreneurs, for emerging companies, and for enterprise ventures," explained Alan Winters, U.S. Head of Business Development at MobiDev, in this SYS-CON.tv interview at 20th Cloud Expo, held June 6-8, 2017, at the Javits Center in New York City, NY.
The explosion of new web/cloud/IoT-based applications and the data they generate are transforming our world right before our eyes. In this rush to adopt these new technologies, organizations are often ignoring fundamental questions concerning who owns the data and failing to ask for permission to conduct invasive surveillance of their customers. Organizations that are not transparent about how their systems gather data telemetry without offering shared data ownership risk product rejection, regu...
