Ajax
What Is AJAX?
Fundamentally, AJAX represents a generic application model that would enable more interactive, more responsive, and smarter Web applications.
The Web was originally designed for browsing HTML documents. As a result, the classic Web application model adopts a "click, wait, and refresh" user interaction paradigm and a synchronous request/response communication mechanism:
- "Click, wait, and refresh" user interaction paradigm: A browser responds to a user action by discarding the current HTML page and sending an HTTP request back to a Web server. The server completes some processing and then returns an HTML page to the browser. The browser refreshes the screen and displays the new HTML page.
- Synchronous "request/response" communication model: The browser always initiates requests, whereas the Web server merely responds to such browser requests. The Web server never initiates requests—the communication is always initiated one-way. The "request/response" cycle is synchronous, during which the user does not have to wait.
However, these two fundamental behaviors of the classic Web model do not work well for software applications. In the context of software applications, the classic Web application model creates many problems: slow performance due to "click, wait, and refresh;" loss of operation context during page refresh; excessive server load and bandwidth consumption due to redundant page refreshes; and lack of two-way, real-time communication capability for server initiated updates.
In the context of software applications, "click, wait, and refresh" and "synchronous request/response" result in slow, unreliable, low productivity and inefficient Web applications. These two basic behaviors must be altered to produce higher performance, more interactive, more efficient Web applications—precisely what the AJAX application model does. In the AJAX model:
- "Partial screen update" replaces the "click, wait, and refresh" user interaction model. During user interaction within an AJAX-based application, only user interface elements that contain new information are updated; the rest of the user interface remains displayed without interruption. This "partial screen update" interaction model not only enables continuous operation context, but also makes non-linear workflow possible.
- Asynchronous communication replaces "synchronous request/response model." For an AJAX-based application, the request/response can be asynchronous, decoupling user interaction from server interaction. As a result, the user can continue to use the application while the client program requests information from the server in the background. When new information arrives, only the related user interface portion is updated.

What is Microsoft Exchange 2007
Electronic messaging is mission critical, but remains vulnerable to a growing array of threats. Viruses, worms, denial-of-service attacks, spam, legal e-discovery and the need to satisfy a growing set of government regulations all make effective message management increasingly difficult.
Microsoft offers a range of solutions to assist companies in meeting complex e-mail compliance requirements, including hosted services for e-mail filtering, encryption, archiving and continuity assurance that help businesses communicate with confidence. Microsoft Exchange Hosted Services provide enterprise-class reliability for messaging security and management, actively ensuring the security, compliance and availability of electronic communications. EHS helps customers simplify the administration of their messaging environments and are easy to deploy, manage, and maintain. The hosted services model requires no hardware or software installation, minimizes up-front investment and provides a predictable payment schedule through a subscription-based service.
As a component of the Microsoft Exchange solution portfolio, Exchange Hosted Services provide a layer of protection features deployed across a global network of Internet data centers. The services create a security-enhanced message stream to and from your on-premise messaging infrastructure.
HOW IT WORKS
With just a simple mail exchange (MX) record configuration change, our services can be up and running quickly. There is no hardware to provision; no software to buy, install or configure; and no expensive training required for your IT staff.
Furthermore, there is no need for you to change or modify your existing e-mail infrastructure, or to even install and maintain any new hardware or software. The heart of Exchange Hosted Services is its distributed network of data centers located at key sites along the Internet backbone. Each data center contains fault-tolerant servers that are load-balanced from site to site and from server to server. In the unlikely event that one data center is unavailable, traffic can be easily routed to another data center, minimizing the chances of interruption to the service. In addition, Microsoft algorithms analyze and route message traffic between data centers to help ensure secure and timely delivery. With this highly available network Microsoft provides service level guarantees of 99.999% uptime.

Next Generation Workforce
A lot has been written about the next-generation workforce: what it’s like and what a company needs to do to attract and, more importantly, keep it. Although old, there's an interesting article about younger, tech-savvy new workers in the September 19, 2006, issue of The Financial Times "They are the future—and they’re coming to a workplace near you." Only subscribers may access the full article, but there is a preview. |
Bottom line, these new workers live online and are driven by results. They know how to use video conferencing, audio conferencing and any collaboration services needed to get work done. They are more than familiar with using software as a service (SaaS)—in many interviews with junior candidates applying for their first job in Accenture, I found that many of them did their final college work/thesis using Google Docs, sharing and reviewing it with their mentors online. |
You may be asking: What does all this have to do with being green? The answer is: Quite a lot. Put simply, implementing collaboration software and services, such as audio/video conferencing, document sharing and management and, finally, instant messaging, are initiatives that align well with the green agenda as they help reduce travel and commuting. They also help reduce costs, improve productivity and allow your company to work with global teams. |
The next-generation workforce is more virtual than ever. And in this virtual world, reducing the amount of paper needed suits this workforce—and makes it more agile. Electronic workflows make certain processes paperless—the green agenda thanks you very much for that. As does your finance department for saving the costs of paper and printing (maintaining, replacing and buying new printers). By the way, what is your user/printer rate? I know there is no magic number for this, but do you really need all the printers you have? OK, I will talk about printers on another post. |
Another good consequence of preparing for this workforce is perhaps the reduction in the use of office space. Wow!! Not possible!! Think so? Accenture recently saved two floors at its Chicago office, thanks to no longer needing the space because of shift changes among employees, and the technology to support this. Well, multiplying the rental costs for two floors over 12 months will produce good savings at the end of the year. Being able to do this depends on the type of workforce you have, but have you checked whether this is applicable to your business? |
I had a conversation with an Accenture colleague last week, and we talked about a meeting he had weeks ago with the CIO of a big airline company. One of the main concerns of the CIO was the difficulty of attracting and retaining talent. There on the CIO’s desk stood an old computer with Windows 95, using and old e-mail system with zero collaboration (for example, instant messaging or an integrated communication system like the Office Communication Suite) available. Considering the demand for technology this workforce shows, it’s definitely hard to attract and retain talent if they see they do not have the technology infrastructure they need—infrastructure which is aligned with the green agenda. |
The Next-Generation Workforce is more thoughtful than any other category, and they use the modern technology. Perhaps they have not realized yet, but they are green too. |

Free Antivirus Softwares
Top antivirus software should be easy enough for a computer user to both install and install. The software should effectively seek out and identify virus threats, as well as clean or isolate infected files. There should be understandable reporting available for each scan and plenty of help support available, so you can be well-informed of the software’s activities and capabilities. Below are the criteria TopTenREVIEWS uses to evaluate antivirus software.
- Ease of Use – Exceptional antivirus software is simple to use, regardless of a user's computer experience or knowledge of viruses. The software should be easy to install and configure. If you need to use the interface to change settings, it should be intuitive and non-threatening to beginners. Ideally, most features will be enable/disable toggles with the power to fine-tune if desired. The best antivirus software is the kind you simply install on your system and then let it do its work.
- Effective at Identifying Viruses and Worms – The best antivirus products identify infected files quickly through realtime scanning, searching for viruses in a multitude of sources, including email, instant message applications, web browsing, etc. Scanning speed is also important. Slow antivirus software will tend to interfere with your work or gaming, and if it’s very slow or you are particularly impatient, you might have the tendency to stop or pause the scan, rendering the software useless. Generally, antivirus software scans your hard drive and files looking for known viruses.
- Effective at Cleaning or Isolating Infected Files – Truly capable antivirus software thoroughly cleans, deletes or quarantines infected files, keeping them from spreading throughout the hard drive or network. Proactive/heuristic testing enables the antivirus software to detect and quarantine code that looks and acts like a virus even before it has been reported. This could be critical in protecting you on a “Day Zero” attack and spare you from being one of the first casualties.
- Activity Reporting – Antivirus programs should give immediate notification of viruses found by realtime scanners and should provide an easy to read report of scan results, including what was found and what was done with infected files.
- Feature Set – A well-rounded feature set allows antivirus software to provide absolute protection. The best programs are those that offer a wide variety of tools, from basic realtime scanning to more advanced heuristic scanning and script blocking. When it comes to virus protection, the more options the better. Many of the best antivirus packages now include multiple protection schemes at no extra cost. These include antispyware, antimalware, rootkit detection, parental controls and email screening, as many of the new threats are not literally viruses, but rather a variety of malware.
- Ease of Installation and Setup – Antivirus programs should be a breeze to install, making it easy to go from installation to initial scan in just a couple clicks of the mouse.
