As Internet applications grow more complex and versatile, end users' experiences get more colorful and interesting. However, rich Internet applications (RIAs) also place a far greater performance demand on Internet browsers, which have to orchestrate the expanding variety of Internet elements and objects.So, the "wow factor" carries a price: Service providers must understand what is happening outside of their own firewalls, load balancers and server applications. Also, service providers must monitor and report uncontrolled content delivered by third parties.Today's active Web users are encountering RIA technology at more and more Web sites. Users experience RIAs in ad servers (such as dancing cowboys), price tickers and news feeds, and prosaic functions such as searches, collaboration tools and mapping functions.Internet service providers are spicing up their product offerings with bill presentation services for banks, complex inventory management for online retailers and store … [Read more...] about EXPERT ADVICE Managing Web Performance When the User Is King

Web usability guidelines aim to help you keep and serve your customers, rather than driving them to your competitors' sites out of frustration. Usability is important for every Web site, but becomes absolutely vital when a large portion of your revenue comes from Web sales. Over the years, I've read many articles and checklists about Web site usability, and they always mention the importance of site responsiveness.How does responsiveness stack up against other aspects of site usability? There are many ways to slice the usability pie, and each author seems to offer a different taxonomy; here is mine. To satisfy customers, a Web site must fulfill four distinct needs: availability, responsiveness, clarity, and utility. This list presents the four essential qualities in order of their significance, and applies to all first-time visitors.A site that's unreachable, for any reason, is useless. Having reached the site, pages that download slowly are likely to drive customers to try an … [Read more...] about OPINION When Is Your Web Site Fast Enough?
Times change quickly on the technology landscape. Yesterday's marvel is soon replaced by a better, faster, sleeker animal -- one built of bits and bytes and technological innovation that just a few years earlier seemed like the stuff of dreams.Such is the story of the Internet. Some call it Web 2.0. Or simply, the New Internet. By any name, it is far more fluid, interactive and far-reaching than ever before. Compare it now to its infancy, and it's almost like comparing a modern racecar to a Model T.Recently the media have been abuzz with discussions of these new concepts and technologies. Web 2.0 is an umbrella term that seems to embrace every popular new Web trend, but Rich Internet Applications (RIAs) built using new technologies like Ajax and/or Flash are a solid technical development that some e-commerce sites are already deploying. As always, new technology creates new opportunities for those who can exploit it successfully, but also presents them with challenges. So what is a … [Read more...] about OPINION Web Applications: Richer or Poorer?
Networking The data sources and also the raw data needs to be published and indexed in index/discovery servers and a search and discovery mechanisms should be able to find relevant data and/or sources to obtain the data based on contextual (i.e., time, location, type, etc.) information.

No matter how much you change your desktop background image and switch distro themes, staring at the same computer's screen day in and day out can become humdrum. Conky can be used to decorate the desktop in endless ways and provide a stream of useful system monitors in the process.Conky is a system monitor that is sometimes part of the default desktop display in Linux distros. It scans your system's hardware to match a list of possible sensors and creates a display for you to monitor on your root desktop or in its own window. Conky also can be configured to execute external programs or scripts.This system-monitoring app displays a variety of status reports. These include CPU activity, disk usage, memory used and remaining, temperature, emails, clock, swap space and more on your desktop in various appearances.Once you get Conky installed and configured, it works well. It is a passive display with no user interaction needed. But it is cranky to set up. I like the concept behind the … [Read more...] about LINUX PICKS AND PANS Conky: Cool System Monitor, Clunky Setup

What do field sales employees, medical personnel and home-office workers connecting remotely to a central site have in common? A need for up-to-the-minute information. As a common method for near-instantaneous business communication, e-mail can be sent and received in many ways -- via pagers, cell phones and the like. One option that holds especial promise for increasing the timeliness of information flow is Web-based e-mail.However, many businesses choose not to deploy Web mail because of the perceived security risk of Web-based applications in general. Understandably, companies do not want to increase the risk of exposing corporate e-mail systems to external threats. Viruses, spam, worms and other events, both malicious and non-malicious, can bring e-mail infrastructures to their knees. And with recent government legislation in countries such as the United States, e-mail confidentiality has become a growing concern.So, what approaches can a company consider for deploying Web mail … [Read more...] about INDUSTRY INSIDER Tackling the Secure Web Mail Challenge
Microsoft announced Wednesday that it will add a "do not track" option to the next version of Internet Explorer 9 when it is released in 2011. The Tracking Protection feature is a privacy tool designed to help keep third-party websites from monitoring users' Web behavior by letting users filter content on a page that may have an impact on privacy.Tracking Protection joins an existing privacy tool already in IE8: InPrivate Browsing helps users control what the computer remembers about their browsing activity.Third-party sites that track browsing activity can build user profiles. While this practice can provide personalization benefits to users, it often takes place without their knowledge or permission, causing privacy concerns that recently prompted government action.In late November, the Federal Trade Commission renewed the online privacy debate with a report that addressed the issue of Internet tracking, recommenting "more effective technologies for consumer control" via "a … [Read more...] about IE9 to Let Privacy-Minded Web Users Leave No Tracks
