This is the culmination of a 3 year project, from the earliest stages of planning and hoping to the final stages of a completely redesigned site (courtesy of Nate Hill), running on a new CMS (Drupal of course), with mostly new content and a lot of content removed, and we’ve turned over all content maintenance directly to the staff.<br /><br />The coolest thing, in my humble opinion, is that we’re asking all of our staff to write content (in the form of blog posting) that shows up throughout the site. Why is that cool? First, I do mean all–pages, librarians, aids, managers, clerks, library assistants…from all branches and departments. We’re not choosing who gets to write based on classification or degree-status. To me, that’s only right, but for some reason it seems to surprise a lot of library people. Second, we’re a rather large library and have 300 staff already signed up to write for us. That is a lot of staff! Oh, did I mention we’re not pre-moderating either? When staff click ‘Save,’ it’s up live on the site. We trust them.<br /><br />What I’ve discovered about myself as a project manager as I work through this gargantuan project is that I am rather informal in the way I tackle things. We’ve got an actual to-do list, which changes daily. People sign up for what they’re responsible for, do it, and I talk to everybody daily to see where we’re at. This too is informal, e.g. over coffee at Philz in the morning. But no project management software is being used, no fancy tracking spreadsheets (I started with one but gave it up).<br /><br />We currently have an 8 page to-do list for our Digital Futures team right now, with the scary big issues listed at the top (also listed on my white board — see photo) and the more detail-oriented stuff listed below that. And you know what? It works. And what is the lesson I take away from all of this?<br /><br />It doesn’t have to be fancy to work.<br /><br />I think there is an inherent expectation that we’re supposed to use fancy tools to track projects, progress, and staff time expenditures. And granted, those tools are cool…and make for impressive show-and-tells to the management. But if doing something simpler works, don’t choose the complicated option just to look more impressive. Simple is always better.<br /><br />The other thing I’m learning about myself as a project manager is the following:<br /><br />Trust your staff.<br /><br />I realized the other day that I do actually trust my staff to be doing what they’re supposed to be doing. I’m not asking them for a checked-off list every day of what they’ve accomplished, or riding them on arbitrary sub-deadlines. They know when we go live, they know the work that needs to be done, and they’re budgeting their own time, burning the candle at both ends to meet that deadline, and letting me know when it doesn’t seem possible. Our staff, all of them–not just Digital Futures, were hired because they had a skill set we wanted. They are professionals and we trust them to do their jobs. And that’s my job–to trust them to do their jobs, and to remove any and all barriers as they pop up along the way. And there have been a few.<br /><br />It’s weird to me that my job no longer involves the direct creation of content. I’m not coding any more. I’m not writing for the web any more. I’m the way-maker, the barrier-smack-down-er, the black ops ninja style manager who gets things through that no one thought would get through. There must be something to this whole ‘trusting your staff’ phenomenon, yes? To keeping things easy, straight-forward, and efficient. So, to all the fancy management theory and software to make you more efficient and track your employees better, I say: Screw it. Do your job and let others do theirs. We all get more done.Raj Vaishnawhttp://www.blogger.com/profile/04513071956356747186noreply@blogger.com0tag:blogger.com,1999:blog-2629130971807160423.post-12275857347979969072010-11-15T09:34:00.000-08:002010-11-15T09:35:13.324-08:00Choosing a Web Content Management System: 8 Pitfalls to AvoidMaintaining a strong web presence is fundamental for any serious organization today. For a business, their web site is typically the first stop for prospects on their way to a purchase decision—and the place where customers go for support and information after a purchase. Likewise, many organizations today create intranets or extranets to foster communication and collaboration with their employees, customers and partners. These sites are often portals which integrate third party web applications, document management systems, and user personalization, and may touch thousands or even millions of people. Educational and governmental organizations also require a strong presence. Their web site may convey important information to their constituents, present key information for current or potential students, or allow information sharing among employees. From a marketing perspective, the evidence is indisputable: Respondents to a 2009 Aberdeen Group survey overwhelmingly indicated that their top marketing channel was their web site, followed closely by e-mail marketing activities.<br /><br />Creating and maintaining an effective web site, intranet, or extranet that is continually updated with fresh content can be challenging. Traditionally, the people responsible for creating content were forced to turn to the IT department in order to get it published. Many organizations still operate this way, but it’s increasingly become more expensive and impractical to utilize this approach. With IT juggling multiple tasks, managing web content becomes just another to-do item in a long list of priorities. Content owners become frustrated because it takes too long to get their material on the web, iterating content changes add frustrating delays, and IT staffers are pulled away to tasks that may add more value to the company’s bottom line.<br /><br />Responding to changing demands can also be an issue. As needs change over time, the web site must be flexible enough to respond to the changes and allow users and site administrators to reconfigure pages and content on individual pages.<br /><br />A faster and more efficient route is to deploy a web content management system (CMS) that is both user-friendly and cost effective. Finding a good CMS that fits a company’s web and business strategies is another matter. The number of CMS products on the market has grown substantially over the years, with both proprietary and open source solutions available. But organizations should carefully consider what to look for in a CMS—and the pitfalls to avoid. Let’s take a look at some of the key issues to consider before making a decision on a CMS system.<br />Closed v. Open Systems<br /><br />There are many “closed” (proprietary) CMS systems on the market. But closed CMS platforms bring significant challenges. First, they almost always include hidden costs. If the CMS system does not perfectly match your business needs out of the box, you’ll pay the vendor extra—maybe a lot extra—every time you want to add new features to your web site. It’s a good idea to do a detailed cost breakdown on a proprietary CMS system. In typical scenarios, the cost for purchasing proprietary CMS software represents only about half the price of getting a system that functions according to your organization’s needs and specifications. Because there is a relatively small pool of technical talent that has the expertise to customize a particular closed system, that talent can get away with charging a lot of money for their work.<br /><br />Open source CMS systems are distributed at no cost and make their full source code available to developers. If an open source CMS achieves significant market adoption, this approach can encourage innovation among third parties who create add-ons for the open source core and allow much more freedom for market principles to work. This may result in a wide range of products and solutions you can use to customize your CMS system at a much lower price than in a proprietary system. If there is high demand for particular functionality in a popular, open source CMS system—for example, e-commerce capabilities—third-party developers will respond, innovate, and compete with one another. It is a win-win scenario because organizations can install a highly functional, affordable CMS system that is easily customized to meet current and future business requirements. At the same time, it unleashes the creativity of third-party vendors who can deliver great products in a competitive marketplace.<br />User Experience<br /><br />As noted above, there are still organizations where employees rely on the IT department to publish web content. This is an expensive approach that introduces significant delays. But there’s a simple reason why it still exists: some CMS tools are not designed for non-technical users. Organizations looking to replace or upgrade their CMS systems, or install one for the first time, should gravitate towards CMS platforms that offer built-in, easy-to-use text editors and which allow users to easily add pre-defined functionality to their editable web pages. These systems typically require minimal training and might be as simple as showing content owners how to use an easy-to-use content editing tool. Assuming most web content owners already know how to use PC-based word processing tools, non-technical employees can begin posting their content as soon as the system is installed, reducing or eliminating the need for IT assistance.<br />Scalability<br /><br />You expect your business to grow and expand over time—and your web site should be able to keep up. Many CMS systems are adequate when an organization is small, but cannot scale as the organization grows. If your CMS is not scalable—if it cannot grow in tandem with your business—it can be very expensive and complicated to migrate your web content to a new system capable of providing more features and handling more site visitors. Be sure to find out whether a potential CMS system can run in a web farm, where server hardware can easily be added to accommodate growing numbers of web site visitors.<br />Controlling Content<br /><br />Your web site may be the public face of your organization or the primary portal for your employees to collaborate and access your digital assets so there is considerable risk if you don’t have good tools to control what, when, and how content is published. Serious damage can be caused even by your best employees through inadvertent publication of sensitive or incorrect information. When looking at CMS systems, find out whether they include easy-to-use tools and features that allow business managers and IT administrators to establish granular user permissions and automated content approval processes. These features are critical in ensuring that only authorized users are allowed to post content in specific areas of your web site, and that all new content goes through a content approval process before it goes live.<br />Technical Support<br /><br />The level of outside support you can find for a given CMS system varies wildly, especially among open source solutions. On one end of the spectrum is the professional support you expect to receive with a proprietary system— typically at a high price. On the other end are free open source solutions, which may offer only online advice from the user community, and their community may be small. Some open source CMS systems which have a more solid business foundation provide a middle ground to these two extremes. These open source-based businesses may offer mission critical support options to the users of their software with support which is often indistinguishable in responsiveness and quality from proprietary CMS vendors. At some point, your organization will likely need help with your CMS system, whether it’s a question about a patch or something more significant like advice on a site migration.<br />Partner Network<br /><br />Another important factor to consider—one that is sometimes overlooked—is who can help you build and modify your web site. Your needs a few years from now may require enhancements and additions to your web site that are not on the radar today. So it’s important to look at the community of web design firms, web hosting companies, training providers, software companies, and others who know and support a particular CMS system. Look for a CMS platform that comes with a rich “ecosystem” of partners who can provide a broad range of services and solutions to help you get the most out of your CMS investment. This is especially important for open source CMS solutions where a rich ecosystem of third-party software developers can generate a large variety of software add-ons which can quickly, inexpensively add functionality to your web site.<br />Update Notifications<br /><br />Software usually evolves over time. You might get by using older versions of some software. However, it’s important to keep CMS systems updated to keep current on security patches and new features that can deliver more web site functionality. Open source CMS packages may offer no notification when a feature has been added or modified or when a security vulnerability has been identified in the software. You may be forced to continuously monitor the open source community to identify new patches and security concerns. Again, some open source CMS systems which have a more solid business foundation, offer proactive email alerts for notifications of patches, security updates, and other changes that will keep your CMS running smoothly and safely.<br />Licensing<br /><br />Licensing can be one of the most confusing—and potentially costly—aspects of acquiring a CMS system. All CMS system licenses come with a variety of privileges and restrictions. If there is any possibility your organization may build an application on top of a CMS system—for example, your developers might create a solution for a specific vertical industry that you will sell—it’s important to know whether you can sell the product while retaining the rights to your intellectual property. Some commercial licenses restrict you from reselling or redistributing a CMS system. Some open source licenses such as the GPL have restrictions which require you to contribute all of your proprietary code back to the open source community. Business-friendly open source licenses such as the BSD license provide the maximum freedom, allowing you to retain and commercialize your intellectual property.<br /><br />Creating and maintaining a web site is a necessity in today’s marketplace if you want to grow your organization and communicate effectively with the customers, suppliers, employees, and partners who help your business thrive. Knowing what pitfalls to avoid when searching for a good content management system is an important step in making sure that your web site fills its mission as a vital business asset.<br /><br />==Raj Vaishnawhttp://www.blogger.com/profile/04513071956356747186noreply@blogger.com0tag:blogger.com,1999:blog-2629130971807160423.post-70650243555249172552010-05-10T21:48:00.000-07:002010-05-10T21:48:45.849-07:00CSS and DesignIn many ways, type will be the actual workhorses from the Web, yet that does not imply they need to end up being basic. Till Cascading stylesheet use grew to become widespread, little could be done to change the way in which type as well as type elements looked on the internet. Standardizing textual content area measurements among Computer as well as Macs would be a issue since the different os's interpreted persona thickness differently; furthermore, the field dimensions can vary greatly through internet browser in order to web browser.<br /><br />Cascading stylesheet form style gives the artist additional flexibility, each in order to integrate and also isolate the shape as well as type factors. Textual content areas, for example, can take on a tone of your web site's qualifications coloring or even follow exactly the same typeface used about the web page. Likewise, it is possible to sketch focus on the form by itself by giving it the different background; this particular lets you format prolonged drop-down databases for straightforward studying.<br /><br />Encompassing the actual Form<br /><br />The proper execution tag is really a that contain element in which, such as the div label, is not taken simply by fall behind. Both tickets, in fact, may be styled with Css -- you may also situation a form on the web page by means of Cascading stylesheet terms. Internet browser help varies with regard to a few of the much more weird Style sheet attributes placed on the proper execution label, yet more prevalent attributes for example backdrop color and also national boundaries tend to be rendered appropriately generally. On top of that, when Style sheet does not help specific attributes, these types of characteristics are merely disregarded as well as the form renders admittedly.<br /><br />Frequently, an internet page just has a single type. Inside these kinds of situations, styling the shape tag by itself may have the required outcomes. For example, this Cascading stylesheet guideline provides the entire kind the vivid orange backdrop plus a azure edge:<br /><br />kind<br />background: #FF9900;<br />border: thin solid #0000FF;<br />padding: 10px;<br /><br />Padding is put into switch the proper execution factors within from the ends. Should your page contain several form as well as you need to type each one in a different way, produce a Css Identity selector for every kind. With this situation, pick the sophisticated selector within the newest Css Principle dialog box and also enter a distinctive Identity - such as form#topform or even form#bottomform -- inside the Selector area. Additionally arranged the particular Identification of the kind licence plate while that way.<br /><br />Altering Input Fields<br /><br />One manner in which the proper execution as well as div tickets vary regarding Css is incorporated in the few monetary gift. Factors just a kind don't inherit the actual Css qualities from the type, yet factors just a div tag perform inherit the actual div's Css capabilities. You should, therefore, get one more route with regard to design every one of the textual content career fields inside a provided kind. The simplest way in order to have an effect on several kind elements all at one time is always to fashion the input label. You could remember the input label can be used to create textual content fields, stereo switches, checkboxes, as well as Publish control keys.<br /><br />As an example, this particular Cascading stylesheet guideline provides all the input elements a standard backdrop coloring and also a particular coloring, well, and size for the text career fields:<br /><br />feedback<br />background-color: #F5F5F5;<br />color: #660099;<br />font: 10px Verdana, Arial, Helvetica, sans-serif;<br /><br />Cascading stylesheet styles the textual content fields for preliminary textual content and also text joined through the person.<br /><br />Suggestion: Keep in mind that a multiline textual content field is often a diverse label textarea than the single-line text field. You need to create a Cascading stylesheet guideline with regard to each enter as well as textarea tags.<br /><br />Among the best makes use of with regard to Cascading stylesheet and text career fields is actually environment the actual size. Using this method is much more versatile and responsive than while using Char Width field about the Home inspector for each individual textual content field. It is advisable to set the actual width on the Cascading stylesheet course rather than adjust this directly within the Cascading stylesheet guideline for that input tag. The reason why? The actual size environment not merely has an effect on every one of the single-line textual content career fields, it adjusts checkboxes and stereo control keys: which are feedback tickets. Following a Css guideline is actually identified, arranged the class of the selected textual content industry in the Home Inspector.<br /><br />Distinguishing Lists and Menus<br /><br />The choose list/menu item consists associated with 2 tags: select as well as alternative. The actual select label may be the total box to the checklist items; utilize the choose label to be able to type the actual size, font, as well as typeface dimensions of all drop-down databases on the web page evenly. Individual checklist products could be formed through environment the school for the separate choice tags. Although this procedure should be carried out by hand and is fairly tiresome, it will available the actual doorway to many options.<br /><br />For those who have a very lengthy drop-down listing in which carries a wide-range regarding products structured through category, along with cautious Style sheet hair styling, principal group headings could be in a single color as well as subitems inside another.<br /><br />Changing Labeling and also Legends<br /><br />A form is actually greater than a assortment associated with textual content areas as well as checkboxes; labeling enjoy a good incredibly important part within form business and also user friendliness. Form labels in many cases are utilized within one of two ways. The conventional method is to location most of the labeling within a column of the desk, along with the proper execution components within an additional. Creative designers are also increasingly using the label label as a way regarding increasing convenience. Any Dreamweaver Style sheet methodology is available for whichever path you are taking whenever labeling your forms.<br /><br />In the situation where all of the labeling tend to be arranged in the desk column, it is best to produce a Cascading stylesheet class for the labels as well as put it on towards the td tags. The most efficient way to do this would be to very first choose the actual column that contains labels and then choose the required course in the Type list on the Home inspector. Dreamweaver is applicable the selected course to be able to all the td tissue within the column.<br /><br />If your layout uses brand tags, Css manage is actually even easier. Add a particular Css type for the brand tag to produce the standard appearance for those your own labels. Take note that you might nevertheless have to adjust the proportions from the name column individually since environment the particular thickness within Cascading stylesheet for that label label doesn't have result.<br /><br />2 other form-related tickets: fieldset and also legend -- can be found regarding Style sheet styling. Because described previously within this section within the sidebar "Grouping Form Controls," the two are utilized jointly in order to aesthetically connect associated form components. Fashion the actual fieldset tag to change the actual setting out edge or perhaps include padding on the advantage from the national boundaries. Alter the tale fashion when you need allow it a different backdrop color and/or edge.<br /><br />Highlighting Focus<br /><br />Want to focus the actual interactivity of the kind? Cascading stylesheet carries a pseudo-element selector (what are known as since it is actually appropriate only if an element is within a particular state) that takes effect whenever a kind element is chosen. The actual Cascading stylesheet selector will be:concentrate also it works with enter, choose, and textarea tickets.<br /><br />To generate any:emphasis selector, adhere to these types of actions:<br /><br />One. Select Brand new Cascading stylesheet Principle on the Style sheet Designs panel.<br /><br />2. Within the brand new Css Guideline dialog package, select the actual Superior selector option.<br /><br />3. Get into the the particular label you need to have an effect on then:concentrate inside the Selector area. As an example, should you wanted to change all the textual content areas, r / c buttons, checkboxes, and control keys if they get concentrate, enter enter:concentrate.<br /><br />4. Click Okay to close the brand new Style sheet Guideline dialog as well as open up the particular Cascading stylesheet Guideline Description dialog.<br /><br />5. Choose the required styles from the various categories and click Okay if you are done.<br /><br />Survey the particular site in a compatible browser such as Mozilla Opera, Netscape half a dozen or even much better, Safari, and so on to experience the actual Css changes. Take a look at cheap website templates.<br /><br />Extreme caution: Sadly, the:concentrate selector isn't reinforced within any kind of version associated with Internet explorer, around this creating. You are able to, however, simulate the impact by activating JavaScript features using the onFocus() as well as onBlur() activities which manipulate the course capabilities.<br /><br />Web design is a passion of mine.

That’s certainly a wise thing to do, considering Google totally dominates the search market. But, there are still other search engines that some people are using, so it is wise to make sure your site is performing to the best of its ability in those too!<br/><br/>Obviously the other two engines are Yahoo and Bing and whilst Yahoo is seemingly declining fast, Bing is actually gaining a market share. Furthermore, if the deal between Microsoft and Yahoo goes through, Bing search will be talking over Yahoo anyway. With the muscle of Microsoft behind Bing, you can be sure the search engine won’t be prepared to play second fiddle to Google for long!<br/><br/>However, unlike Google, we don’t hear much about what Bing wants out of a site for decent rankings, but Rick DeJarnette of Bing Webmaster Center has shared some dos and don’ts of link-building for Bing. Not surprisingly, a lot of his advice for complying with Bing’s policies, does not differ too much from the advice that Google would give you. It is however, still always nice to hear what they think, just to clear up any possible confusion.<br/><br/>Like Google, Bing places great emphasis on quality links to determine its rankings. “Just don’t make the mistake of believing it will result in instant gratification. Successful link building efforts require a long-term commitment, not an overnight or turnkey solution,” says DeJarnette. “You need to continually invest in link building efforts with creativity and time.”<br/><br/>What You Should Do!<br/><br/>DeJarnette shared some tips for getting more quality links. The following are Bing’s tips for effective link building (paraphrased):<br/>1. Develop your site as a business brand and brand it consistently<br/>2. Find relevant industry experts, product reviewers, bloggers, and media folk, and make sure they’re aware of your site/content<br/>3. Publish concise, informative press releases online<br/>4. Publish expert articles to online article directories<br/>5. Participate in relevant conversations on blogs/forums, referring back to your site’s content when applicable<br/>6. Use social networks to connect to industry influencers (make sure you have links to your site in your profiles)<br/>7. Create an email newsletter with notifications of new content<br/>8. Launch a blog/forum on your site<br/>9. Participate in relevant industry associations and especially in their online forums<br/>10. Strive to become a trusted expert voice for your industry, while promoting your site<br/><br/>What You Should Not Do!<br/><br/>DeJarnette shared a list of things that you should avoid in your link building efforts, if it is a good Bing ranking that you are after. Here is what Bing says will get your site reviewed more closely by staff:<br/>1. The number of inbound links suddenly increases by orders of magnitude in a short period of time<br/>2. Many inbound links coming from irrelevant blog comments and/or from unrelated sites<br/>3. Using hidden links in your pages<br/>4. Receiving inbound links from paid link farms, link exchanges, or known “bad neighborhoods” on the Web<br/>5. Linking out to known web spam sites<br/><br/>“When probable manipulation is detected, a spam rank factor is applied to a site, depending upon the type and severity of the infraction,” says DeJarnette. “If the spam rating is high, a site can be penalised with a lowered rank. If the violations are egregious, a site can be temporarily or even permanently purged from the index.”<br/><br/>Most of the stuff DeJarnette shared is nothing any experienced search marketer is not already aware of, but it can be quite helpful when a search engine itself lays out what to do and not to do, to help webmasters get better rankings.</p>in reference to: <p><blockquote>"Link-Building Policy for Bing"<br/>- <a href='http://www.freshwebz.co.uk/blog/'><a href='http://www.freshwebz.co.uk/blog/'>http://www.freshwebz.co.uk/blog/</a></a> (<a href='http://www.google.com/sidewiki/entry/raj.sandia/id/OYzcBXnxcOOdIIWpIj0HtxOw5-U'>view on Google Sidewiki</a>)</blockquote></p></div>Raj Vaishnawhttp://www.blogger.com/profile/04513071956356747186noreply@blogger.com1tag:blogger.com,1999:blog-2629130971807160423.post-69236930156529230642009-12-22T02:58:00.001-08:002009-12-22T02:58:36.860-08:00Google Sidewiki entry by SEO Expert<div xmlns='http://www.w3.org/1999/xhtml'><p>Banners have been a major part of the World Wide Web world since its early days. Copywriters burn the midnight oil looking for new designs that will grab the visitor’s attention and compel him to click on their banner. This article discusses some of the most successful banner designs.<br/><br/>Teasing your curiosity<br/><br/>“Do Not Click Here”. How many of you have seen this slogan in a banner? What did you do when you first saw it? If you are like most people, when you first saw it, you clicked on it. What makes this simple sentence so powerful that it compels the visitor to click on it? The answer is curiosity !!!<br/><br/>Copywriters and web designers are always looking for ways to arouse the website visitor’s curiosity. As banner designers their goal is to attract the visitor to the banner, usually completely ignoring the other elements on the web page that are more important to the website owner. However, because the “Do Not Click Here” slogan tells us nothing about what is on the next page, it arouses the visitor’s curiosity and makes it almost impossible not to click on this banner to see what’s behind it.<br/><br/>Simple integrated design<br/><br/>When Larry Page and Sergey Brin first introduced their product, “Google”, to potential investors, they mentioned Adwords as a backup option in case they didn’t make any money. We all know how lucky they were that they eventually needed to use that backup plan. What made these “boring” ads such a great success?<br/><br/>Unlike other ads, Adwords neither arouse the visitor’s curiosity nor disturb the main flow of the web page. In fact, the opposite is true. Adwords are meant to look like part of the search results giving the user the feeling that those ads are there because he asked for them. No one has any doubt that this simple design helps Google to promote both their search engine and the Adwords advertising program.<br/><br/>Take part in the action<br/><br/>Banner designers wisely used interactive technologies like Flash to develop type of banners that invite the user to take part in the action. Drawing the user into the action can be accomplished in many creative ways. Some web designers use popular old games elements as part of the scene. You all know the famous game pacman. One of the banners that I like the most is the one where the user is allowed to let pacman “eat” few dollar signs. At the successful completion of this mission, a nice slogan is revealed asking him to open a saving account that will earn money with a fixed interest rate. The idea behind those interactive banners is simple: Let the user take part in the action and then at the right moment when his mind is less resistant, show him the sales message. Those interactive banners proved to be very efficient. Their biggest disadvantage is that most webmasters will not allow that kind of banner because it distracts too much from the web page content.<br/><br/>Back to Black and White<br/><br/>Website designers are always seeking to be different with their design ideas. One banner fashion trend that can be found lately is Black and White banners. Although research shows that blue and yellow are the most efficient color to use in a banner, Black and White banners have been seen a lot lately. It’s probably something that will eventually vanish, but the idea behind it is to be different and to make the user wonder what’s up and hopefully click on the banner to find out.<br/><br/>Get Out of the box<br/><br/>Have you heard about the <a href='http://mrfdesign.we.bs'>mrfdesign.we.bs</a> If not, check out this website before continuing to read this article. This website has proven that creative thinking not only can bring you money but also create a whole new trend. Right after the <a href='http://milliondollarhomepage.com'>milliondollarhomepage.com</a> got the internet community’s attention, many designers used this idea to deign a banner on which they sell a 10x10 pixel area.

A web designer needs to consider a variety of online selling principles while designing an eCommerce website. In this article we will try to take a look at some of the major design aspects that you must have in an eCommerce website.<br/><br/>Many of you are probably already asking why eCommerce website design is different from any other website design. They all need to be attractive, well organized and use the right colors that fits the website spirit and so on. Your instincts are good. However a close look at some successful eCommerce websites will reveal the conceptual differences that are typical in a successful eCommerce website.<br/><br/>An eCommerce website needs to follow certain selling principles:<br/><br/> 1. Give the user a pleasant experience during his online shopping.<br/> 2. Make certain you provide sufficient information on who owns the website and why they should be trusted.<br/> 3. The website must be easy to use. If it isn’t, the visitor will go to your competitor.<br/><br/><br/>Those principles are not new. We all know those basics from our day to day experiences in the mall, shopping center and every other market place that is waiting for us to open up our wallets. The big challenge for a web designer is how to translate those conventional marketing techniques to the virtual world of the internet. I’m sure you’ve all noticed that in most supermarkets the bread stand is placed at the far end of the building, yet you can smell the fresh bread at the entrance (sometimes they even use a special air duct to carry the smells). That has been done deliberately. Marketers use our sense of smell to draw us through the store where we are exposed to all sorts of tempting goodies as we go to get our loaf of bread.<br/><br/>How do you draw an imaginarily path in a web page? A path designed to lead the visitor to do what you want him to do…make an online purchase. Unlike the supermarket our website has no smell. In a website the distance from one point to the other is pretty much the same, so the exit is always right there. In a website you can try to order the “shelf” in the way you think will best expose the visitor to many of your products, but there is always a chance that he will find a short cut to another page that can also be the way off your site.<br/><br/>As can be see, although putting your products on the web is much easier then renting space and opening a supermarket. However, selling your products on the web can be difficult.<br/><br/>A good eCommerce website design will lead the visitor to the right page in one click or two at the most. Sometime web designers will use techniques that would never be considered for non-eCommerce websites. Everyone has seen at least one sales letter website. On these web pages the only link is to the order form. Sales letters are not the most typical eCommerce website because they usually sell only one product. That allows the web designer the ability to exaggerate the one click principle and make it an advantage. All the facts about the product have been presented to the user is a smart way while every few lines he has the option to click on the order form. If he is not yet convinced he will have the option to continue to read more facts and testimonials about the products. Believe it or not, those sales letter websites are actually selling.<br/><br/>“What about online shops?” Online shops have to deal with more then one product. Of course, the greater number of products increases the complexity of the website. Sophisticated eCommerce websites use a variety of personalization technologies in an effort to determine the best selection of products to offer to the visitor. Personalization technologies are a major part of advanced eCommerce websites. However this topic is beyond the scope of this article. The cleverness of an eCommerce website’s personalization technology has a major influence on its design. The first to use such technology was Amazon.com who decided</p>in reference to: <a href='http://www.whitehouse.gov/'>The White House</a> (<a href='http://www.google.com/sidewiki/entry/raj.sandia/id/ieplbM9ET8xleTFYxAn63gPR8kY'>view on Google Sidewiki</a>)</div>Raj Vaishnawhttp://www.blogger.com/profile/04513071956356747186noreply@blogger.com0tag:blogger.com,1999:blog-2629130971807160423.post-67471259179271540422009-12-22T02:56:00.003-08:002009-12-22T02:56:44.308-08:00Appearance, Usability and Search Engine Visibility in Web Design<div xmlns='http://www.w3.org/1999/xhtml'><p>Appearance, Usability and Search Engine Visibility in Web Design<br/>by Christopher Heng, <a href='http://thesitewizard.com'>thesitewizard.com</a><br/><br/>I was recently asked by a visitor to <a href='http://thesitewizard.com'>thesitewizard.com</a> to take a look at her company's website, designed by a university student.

Some Basic Usability Tips for Commercial Websites<div xmlns='http://www.w3.org/1999/xhtml'><p>Following my article on Appearance, Usability and Search Engine Friendliness in Web Design where I discussed the importance of looking at the usability and search engine visibility of a website, I have received countless messages from visitors to <a href='http://thesitewizard.com'>thesitewizard.com</a> asking me to review their website. While I do not have time to answer such requests individually, I decided that an article outlining some glaring usability flaws that I have found in a number of websites in general would be helpful. This article thus deals with the myths and fallacies commonly believed when designing a website to sell a product or a service.<br/>Make It Easy for Visitor to Check Your Price List<br/><br/>Some websites try to hide the price list for their products. Some of these sites only display the price of the item after you hit the "Buy" or "Order" button, or worse, only after you have created an account on their site. Others have a price list, but bury the link to the price list somewhere deep in their site in a place not easily accessible from the main page or the products page.<br/><br/>I'm not exactly sure what the reason behind this is. Possibly, they think that if the customer does not see the price until they click the "Buy" or "Order" button, they will be more likely to buy the item. This reasoning is fallacious.<br/><br/>There are many types of visitors arriving at your site. Let's take the case of the window shopper. If they see something noteworthy on your site, they may make a note of the price so that they can return later if they want the item at some point in the future. If the price of the item cannot be easily found on your site, do you seriously think that they will thoroughly search the site just to find that elusive price tag? Or do you suppose that such a visitor will click the "Buy" button, just so that they can find the price tag at the end of the process somewhere? Or will they go through the bother of creating an account, revealing their personal particulars, just to find the price of an item?<br/><br/>Like the serious shopper, if they cannot find the price, they will simply go to another site. Remember: this is not a brick and mortar store we're talking about, where you need to take time and put in effort to travel to another store. On the Internet, your competitor is only a click away. And the search engines are more than happy to yield thousands of other sites selling the same type of goods or services as you. I realise that there are some brick and mortar stores (usually small concerns) who think that if they don't put a price tag, the customer has to find out the price from a sales person, who will then have the opportunity to persuade him/her to buy that item. Whether or not that is a good idea for a brick and mortar store (and I can think offhand of some types of customers that you will lose even there), it is a bad idea for a web store.<br/><br/>No matter how you look at it, every customer and potential customer will need to know the price of a product. Even the corporate customer buying for his/her company works to a budget. Making it difficult for your visitor to find the price list is a quick way to drive a potential customer away. As has been observed by many usability experts - the average Internet user has the attention span of a flea. If they can't find what they want within the first few seconds of glancing at your page, they will leave. And your competitors will be more than happy to attend to them in your place.<br/>Provide Descriptions and Pictures for Your Products<br/><br/>I realise that the new web designer is beset with contradictory advice about how best to design their site. One set of such conflicting advice is the requirement to be brief and to-the-point so that you can catch that Internet visitor who will only give your web page a few seconds glance before deciding whether to stay or go elsewhere. Contradicting that is the requirement that you describe your products in depth and place pictures of your product, or screenshots if yours is a software product.<br/><br/>The best way to resolve this, I think, is to take a leaf from Amazon.com's book.

Don't worry about what constitutes "small" here, since most of the time, even if you create a big frame, it'll be considered too small by most visitors. This trick has a high annoyance value since your visitors have to view the information through that small little box and scroll continuously to see the text while the rest of the browser window is filled with information they don't really want to read at the moment. With this strategy, visitors cannot resize or maximize the window to make their reading more efficient or pleasurable. This method will allow you to frustrate those hapless souls and, as a bonus, make them leave your site.<br/> 2.<br/><br/> Disable the right click menu of the browser. Nevermind that people need the right click menu for many purposes, and that they can access the same functions through the main menu bar even after you've disabled it. After all, if your aim is to annoy, you might as well make their visit to your site as unpleasant as possible.<br/> 3.<br/><br/> Play background music when they arrive at your page. If that's not enough of an annoyance, make sure you loop the music so that the visitors are plagued by it continuously while they are on your page. If you're feeling particularly sadistic, place automatically-playing music on many (or even all) pages of your site. You don't have to worry about choosing a horrible tune - choose your favourite piece if you like. Since one man's meat is another man's poison, any sort of music tends to annoy most visitors.<br/> 4.<br/><br/> Make every link on your site opens in a new window when your visitor clicks on it. That is, put a target="_blank" to every link. This will annoy visitors since every time they click on a link in your site, a new window or tab will open. Another benefit of this technique is that it makes your site look amateurish.<br/> 5.<br/><br/> Force your visitors to navigate your website using Flash. That is, place all your content in a Flash file - text, pictures, links, etc - even if Flash is not ideal for such content (a straight HTML page is best for those types of content). Make sure that visitors who don't have the Flash plugin enabled or installed cannot see anything or do much on your website. This effectively drives away all mobile users, a group of users that is growing in size, as well as cripple your visitors who have come to expect certain facilities to always be available in their browsers (such as the BACK key and the ability to bookmark specific pages) when they visit websites. Now they will be forced to work through the more limited Flash plugin of their browser with whatever subset of features you deign to provide. In fact, exclusively using Flash for your site content might even help you to drop to the bottom of search engine listings too, thereby reducing the number of visitors to your site. After all, if you don't have visitors, you don't have to think of new ways to annoy them.<br/> 6.<br/><br/> Load your site with pop-up windows that open when your visitor reaches your page as well as when they leave the page. In fact, if you want to annoy them even further, open a pop-up window when they click on links on your site.<br/> 7.<br/><br/> Reduce the navigational usability of your website. Don't put site maps or navigation bars with shortcut links to pages that your visitors will usually want to go such as the "Download" page if you're a software author. If you can annoy your visitors by forcing them to read whole pages of your text before they can find a link to move on to do what they really want to do, so much the better.</p>in reference to: <a href='http://www.whitehouse.gov/'>The White House</a> (<a href='http://www.google.com/sidewiki/entry/raj.sandia/id/av_q0CmW4HTKapO2s_yBWW-vnYA'>view on Google Sidewiki</a>)</div>Raj Vaishnawhttp://www.blogger.com/profile/04513071956356747186noreply@blogger.com0tag:blogger.com,1999:blog-2629130971807160423.post-50124957864190611482009-11-18T06:24:00.001-08:002009-11-18T06:24:20.580-08:00How to Use Different CSS Style Sheets For Different Browsers (and How to Hide CSS Code from Older Browsers)<div xmlns='http://www.w3.org/1999/xhtml'><p>In an ideal world, you only need one set of CSS style sheets for your website, and those styles will work with every browser currently being used. This, as every webmaster soon finds out when he/she uses CSS, is a pipe dream. The modern browsers all have uneven levels of implementation of the CSS standards. As though this isn't bad enough, their implementations are often buggy - and they don't share the same bugs! And when you have solved that tricky bit, you find that your site has certain visitors (often your best customers) who, for various reasons, are using older browsers that have only rudimentary support for CSS.<br/><br/>What most (if not all) CSS-using webmasters want is a way to specify that a certain style sheet is to be used by such and such a browser and not others, as well as to hide other style sheets from older browsers.<br/><br/>The Good and Bad News<br/>The bad news is that there is no standard documented method to include or exclude style sheets from being used by every browser still being used on the Internet.<br/><br/>All is not lost however. The good news is that there are a number of tricks, workarounds and even non-standard but documented methods available that you can use to have your style sheet included by some browsers and not others. The workarounds often rely on known bugs in certain versions of specific browsers.<br/><br/>On the other hand, even with these workarounds and tricks, you will probably find that there are certain browsers that you want to code for but do not have any reliable means to detect and work around. However, at least with the help of the tips listed here, you should be able to design a CSS-based website that works with the most commonly used browsers<br/><br/>Preliminary Tips for Coding<br/>Before you start coding your site using CSS for specific browsers, here are some tips that hopefully will make your life easier.<br/><br/>Design From Scratch<br/>Most webmasters who have had to convert their existing website to CSS say that they find it easier to design their site from scratch in CSS than to try to find a way to reproduce their old layout in CSS.<br/><br/>Another reason for designing from scratch is that CSS allows you to do many things not possible using the old tables paradigm. Rethinking your entire design allows you to take advantage of the new possibilities.<br/><br/>Code to Follow the CSS Standards First<br/>Many of the web designers hanging out in webmaster forums have found that it is far easier to develop their CSS code for a highly standards-compliant browser like Firefox first, and then only later add the workarounds to make their code work on IE, than to code for IE and then try to make it work for Opera, Konqueror, Safari and Firefox.<br/><br/>It is also logical to write for a more standards-compliant browser first: sooner or later, Microsoft is bound to issue a newer version of IE that will have the existing CSS bugs fixed. When they do so, all you have to do is to remove the workarounds which you created and you're done. If you write your main style sheet with styles that are coded in a non-standard way to deal with IE bugs first, you will wind up having to rewrite everything when Microsoft fixes the bugs.<br/><br/>This is not to say that Firefox does not have its own share of CSS bugs. As such, my personal recommendation is to code with the two (supposedly) most standards-compliant browsers first, ie, Firefox and Opera, while at the same time periodically making sure that your CSS code validates with the W3 Consortium's free style sheet validator. You can add the workarounds for IE later.<br/><br/>(If you are not sure what validation means, or how you can get it done, check out my article on HTML and CSS Validation: Should You Validate Your Web Page? at <a href='http://www.thesitewizard.com/webdesign/htmlvalidation.shtml'>http://www.thesitewizard.com/<wbr/>webdesign/htmlvalidation.shtml</a><br/><br/>Use External Style Sheets and Take Advantage of the "Cascading" Aspect of Cascading Style Sheets<br/>One way to handle the bugs and omissions existing in different browsers is to put all your standards-compliant CSS code in a separate (external) style sheet file that is loaded by every browser.<br/><br/>Then, when you find th</p>in reference to: <a href='http://www.google.co.in/'>Google</a> (<a href='http://www.google.com/sidewiki/entry/raj.sandia/id/614CNA5BcjK5XUmLHItcMDpcOhw'>view on Google Sidewiki</a>)</div>Raj Vaishnawhttp://www.blogger.com/profile/04513071956356747186noreply@blogger.com0tag:blogger.com,1999:blog-2629130971807160423.post-47202874906683825512009-11-18T06:22:00.001-08:002009-11-18T06:22:45.051-08:0010 Strategies To Make Your E-Commerce Website A Success<div xmlns='http://www.w3.org/1999/xhtml'><p>E commerce websites have come of age. As customers realize the ease and benefits of online shopping, the popularity of e-commerce websites have soared like anything else. However, with the increase in the number of Ecommerce websites vying for attention, it has become important for them to devise strategies to be better than the competition and attract more traffic. Here are some new trends and techniques that can help your Ecommerce processes.<br/><br/>Focus on User Experiences<br/><br/>Often we concentrate so much on improving the usability of the website that we completely forget about the user experience. The way users feel on the website goes a long way in influencing their purchase options as well as their general perception of the website. Therefore, try to connect with the visitors on intimate level and then build up your branding through strategic marketing techniques.<br/><br/>Provide Customized Messages to Specific Audience Segments<br/><br/>The chances of sales increases when the audience is more targeted. When you segment your audiences, you know about their general common preferences and likes. This will also give you an idea about what segments are useful and most profitable. In turn, you can customize your sales message and make sure they receive more relevant and personalized information and offers.<br/><br/>Create Compelling Content<br/><br/>Content is the only source of direct communication with your website audiences. Therefore, make it as compelling as you can . The main objective of your product page should be sales conversions. Include product images and videos along with content that convinces them to hit the 'Buy' button.<br/><br/>Eliminate Unnecessary Page Elements<br/><br/>A majority of Ecommerce websites carry a bulk of undue weight because of unnecessary page elements like blinking banners, rotating graphics and annoying flash-animations. Attention grabbing works best on subtle levels. Also make sure the information you provide on the website is short and crisp.<br/><br/>Include Videos on the Website<br/><br/>Videos are an emerging source of product promotion with more and more website embedding videos on their websites to promote their businesses. You can upload videos that provide demonstrations of your products and show how they work, exhibit their different features and show how users can benefit from their use. Moreover, video inclusion has certain search engine benefits as well.<br/><br/>Involve your Website Audiences<br/><br/>The three main elements of a successful website are - Content, Communication and Commerce. You need to involve your audiences and make them feel that they are a part of the website. Include a form on audience interaction on your website. Provide them with an option to review the products and participate in forum discussions etc.<br/><br/>Provide Free Shipping Options<br/><br/>A little known secret of the e commerce industry is that shoppers often shy away from buying a product because of the additional shipping costs that are involved. Thus if you decide to waive of the shipping costs, you'll have more sales. If its not a profitable option individually, provide free shipping options for bulk orders.<br/><br/>Optimize Products for Local Searches<br/><br/>While it is great to business on a global scale and cater to international customers, you can get huge visitor traffic with localized search engine marketing. Promote the products on your website on domestic search engines. You can also customize your product descriptions, tutorials, public relations and ad campaigns to suit the tastes of the local markets.</p>in reference to: <a href='http://www.google.co.in/'>Google</a> (<a href='http://www.google.com/sidewiki/entry/raj.sandia/id/ogW2Fa4ivPAWftsVM1PtUx5wUwo'>view on Google Sidewiki</a>)</div>Raj Vaishnawhttp://www.blogger.com/profile/04513071956356747186noreply@blogger.com0tag:blogger.com,1999:blog-2629130971807160423.post-16403988425507174982009-11-18T06:20:00.001-08:002009-11-18T06:20:39.777-08:00How To Enhance The Usability Of Your Homepage Design<div xmlns='http://www.w3.org/1999/xhtml'><p>The homepage of your website is the face of your online presence. It is what makes the first impression on online audiences about your company and business. When people type in the URL of your website, they reach your homepage. The homepage, should therefore present a brief introduction about the website and lure visitors to browse further within. The homepage is perhaps the most important page of the website and thus you need to take adequate measures to enhance its usability. Here are some tips to ensure the same.<br/><br/>Include a Crisp and Catchy Tagline<br/><br/>Draft a tagline for your website homepage that informs about the company and business in a simple sentence. When visitors enter the homepage, they should know what the website and the company is all about just by reading the tagline. In fact, by drafting a catchy tagline you can catch the attention of your visitors and make sure they don't forget you.<br/><br/>Draft a Meaningful Title Tag<br/><br/>The title tag of your homepage should have your company name followed by a very brief description of the website. Avoid using words like 'Welcome' or 'The' that just populate the space and do no value addition. Instead, try to include your relevant keywords and phrases in the title tags.<br/><br/>Cluster All Corporate Information<br/><br/>Website visitors generally don't bother reading about the company. However, there are times when they decide to do business with you only after they are convinced about the company. In such scenarios it is important to have good corporate information on the website. Create an About Us page on your website that is dedicated towards informing visitors all about your company and business and provide a link to it from the homepage.<br/><br/>Focus on Key Tasks of the Website<br/><br/>The homepage of your website should act as a guide for visitors and help them find a browsing route. It should provide a clear starting point to do what they want to do i.e. there should be clear links to the main areas of the website where visitors might be interested in going.<br/><br/>Include a Search Box<br/><br/>The search box is indispensable for any website. Internet users are an impatient lot and they love anything that cuts short the action steps. Search boxes enable visitors to search for the exact information that they need by just entering a query instead of browsing through categories to fins what they need. Make sure your search box is at least 25 characters wide so that it accommodates multiple queries.<br/><br/>Offer Snapshots of Inlying Content<br/><br/>The homepage of the website is where you can showcase things and lure visitors to further explore the website. A good idea is to place snapshots or post the topics of important content within your website. Whether it is a recent article or a report that you have on a certain web page, offer a preview on the homepage.<br/><br/>Use Meaningful Design Elements<br/><br/>The homepage of a website is important and should welcome visitors. However, that doesn't mean you can load the page with useless design elements and flash animations that offer no value but only increase the file sizes.<br/><br/>Kabir Bedi is the senior web consultant at LeXolution IT Services, a reputed offshore web development company that provides an extensive range of web design services and web Development services.

The URLs of the pages<br /><br />organize them into a hierarchy, although the hyperlinks between them control how the<br /><br />reader perceives the overall structure and how the traffic flows between the different<br /><br />parts of the site.<br /><br />Some websites require a subscription to access some or all of their content. Examples<br /><br />of subscription sites include many business sites, parts of many news sites, academic<br /><br />journal sites, gaming sites, message boards, Web-based e-mail, services, social<br /><br />networking websites, and sites providing real-time stock market data. Because they<br /><br />require authentication to view the content they are technically an Intranet site.<br />History<br /><br />The World Wide Web was created in 1990 by CERN engineer, Tim Berners-Lee.[1] On<br /><br />30 April 1993, CERN announced that the World Wide Web would be free to anyone.[2]<br /><br />Before the introduction of HTML and HTTP other protocols such as file transfer protocol<br /><br />and the gopher protocol were used to retrieve individual files from a server. These<br /><br />protocols offer a simple directory structure which the user navigates and chooses files<br /><br />to download. Documents were most often presented as plain text files without<br /><br />formatting or were encoded in word processor formats.<br /><br /> Overview<br /><br />Organized by function a website may be<br /><br /> * a personal website<br /> * a commercial website<br /> * a government website<br /> * a non-profit organization website<br /><br />It could be the work of an individual, a business or other organization, and is typically<br /><br />dedicated to some particular topic or purpose. Any website can contain a hyperlink to<br /><br />any other website, so the distinction between individual sites, as perceived by the<br /><br />user, may sometimes be blurred.<br /><br />Websites are written in, or dynamically converted to, HTML (Hyper Text Markup<br /><br />Language) and are accessed using a software interface classified as an user agent.<br /><br />Web pages can be viewed or otherwise accessed from a range of computer-based and<br /><br />Internet-enabled devices of various sizes, including desktop computers, laptops, PDAs<br /><br />and cell phones.<br /><br />A website is hosted on a computer system known as a web server, also called an HTTP<br /><br />server, and these terms can also refer to the software that runs on these systems and<br /><br />that retrieves and delivers the Web pages in response to requests from the website<br /><br />users. Apache is the most commonly used Web server software (according to Netcraft<br /><br />statistics) and Microsoft's Internet Information Server (IIS) is also commonly used.<br /><br /> Website styles<br /><br /> Static Website<br /><br />A Static Website is one that has web pages stored on the server in the same form as<br /><br />the user will view them. It is primarily coded in HTML (Hyper-text Markup Language).<br /><br />A static website is also called a Classic website, a 5-page website or a Brochure<br /><br />website because it simply presents pre-defined information to the user. It may include<br /><br />information about a company and its products and services via text, photos, Flash<br /><br />animation, audio/video and interactive menus and navigation.<br /><br />This type of website usually displays the same information to all visitors, thus the<br /><br />information is static. Similar to handing out a printed brochure to customers or clients,<br /><br />a static website will generally provide consistent, standard information for an extended<br /><br />period of time. Although the website owner may make updates periodically, it is a<br /><br />manual process to edit the text, photos and other content and may require basic<br /><br />website design skills and software.<br /><br />In summary, visitors are not able to control what information they receive via a static<br /><br />website, and must instead settle for whatever content the website owner has decided<br /><br />to offer at that time.<br /><br />They are edited using four broad categories of software:<br /><br /> * Text editors, such as Notepad or TextEdit, where the HTML is manipulated directly<br /><br />within the editor program<br /> * WYSIWYG offline editors, such as Microsoft FrontPage and Adobe Dreamweaver<br /><br />(previously Macromedia Dreamweaver), where the site is edited using a GUI interface<br /><br />and the underlying HTML is generated automatically by the editor software<br /> * WYSIWYG Online editors, where the any media rich online presentation like<br /><br />websites, widgets, intro, blogs etc. are created on a flash based platform.<br /> * Template-based editors, such as Rapidweaver and iWeb, which allow users to<br /><br />quickly create and upload websites to a web server without having to know anything<br /><br />about HTML, as they just pick a suitable template from a palette and add pictures and<br /><br />text to it in a DTP-like fashion without ever having to see any HTML code.<br /><a href="http://webmanagementindia.blogspot.com/" target="_perent">Web Management India</a><br /><a href="http://websolutiontools.blogspot.com/" target="_perent">Web Solution Tools.</a><br /><a href="http://wrfwebdesign.blogspot.com/" target="_perent">Mrf Web Design</a><br /><a href="http://webmanagementindia.blogspot.com/"></a><a href="http://mrfdesign.we.bs/index.htm" target="_perent">Mrf Web Development</a><br /><a href="http://mrfdesign.we.bs/index.htm" target="_perent">Mrf Web Development</a>Raj Vaishnawhttp://www.blogger.com/profile/04513071956356747186noreply@blogger.com0tag:blogger.com,1999:blog-2629130971807160423.post-24397913153984165312009-01-10T11:16:00.000-08:002009-01-24T15:29:47.622-08:00World Wide WebThe World Wide Web (commonly shortened to the Web) is a system of interlinked<br /><br />hypertext documents accessed via the Internet. With a Web browser, one can view<br /><br />Web pages that may contain text, images, videos, and other multimedia and navigate<br /><br />between them using hyperlinks. Using concepts from earlier hypertext systems, the<br /><br />World Wide Web was begun in 1989 by English scientist Tim Berners-Lee, working at<br /><br />the European Organization for Nuclear Research (CERN) in Geneva, Switzerland. In<br /><br />1990, he proposed building a "web of nodes" storing "hypertext pages" viewed by<br /><br />"browsers" on a network,[1] and released that web in 1992. Connected by the existing<br /><br />Internet, other websites were created, around the world, adding international<br /><br />standards for domain names & the HTML language. Since then, Berners-Lee has played<br /><br />an active role in guiding the development of Web standards (such as the markup<br /><br />languages in which Web pages are composed), and in recent years has advocated his<br /><br />vision of a Semantic Web.<br /><br />The World Wide Web enabled the spread of information over the Internet through an<br /><br />easy-to-use and flexible format. It thus played an important role in popularising use of<br /><br />the Internet, [2] to the extent that the World Wide Web has become a synonym for<br /><br />Internet, with the two being conflated in popular use. [3]<br /><br />How it works<br /><br />Viewing a Web page on the World Wide Web normally begins either by typing the URL<br /><br />of the page into a Web browser, or by following a hyperlink to that page or resource.<br /><br />The Web browser then initiates a series of communication messages, behind the<br /><br />scenes, in order to fetch and display it.<br /><br />First, the server-name portion of the URL is resolved into an IP address using the<br /><br />global, distributed Internet database known as the domain name system, or DNS. This<br /><br />IP address is necessary to contact and send data packets to the Web server.<br /><br />The browser then requests the resource by sending an HTTP request to the Web server<br /><br />at that particular address. In the case of a typical Web page, the HTML text of the<br /><br />page is requested first and parsed immediately by the Web browser, which will then<br /><br />make additional requests for images and any other files that form a part of the page.<br /><br />Statistics measuring a website's popularity are usually based on the number of 'page<br /><br />views' or associated server 'hits', or file requests, which take place.<br /><br />Having received the required files from the Web server, the browser then renders the<br /><br />page onto the screen as specified by its HTML, CSS, and other Web languages. Any<br /><br />images and other resources are incorporated to produce the on-screen Web page that<br /><br />the user sees.<br /><br />Most Web pages will themselves contain hyperlinks to other related pages and perhaps<br /><br />to downloads, source documents, definitions and other Web resources. Such a<br /><br />collection of useful, related resources, interconnected via hypertext links, is what was<br /><br />dubbed a "web" of information. Making it available on the Internet created what Tim<br /><br />Berners-Lee first called the WorldWideWeb (a term written in CamelCase, subsequently<br /><br />discarded) in November 1990.[1]<br /><br />Berners-Lee has said that the most important feature of the World Wide Web is "Error<br /><br />404", which tells the user that a file does not exist. Without this feature, he said, the<br /><br />web would have ground to a halt long ago.<br /><br />Berners-Lee has also expressed regret over the format of the URL. Currently it is<br /><br />divided into two parts - the route to the server which is divided by dots, and the file<br /><br />path separated by slashes. The server route starts with the least significant element<br /><br />and ends with the most significant, then the file path reverses this, moving from high<br /><br />to low. Berners-Lee would have liked to see this rationalised. So an address which is<br /><br />currently (e.g.) "http://www.mrfweb.we.bs /document/pictures/illustration.jpg" would<br /><br />become http:/uk/co/examplesite/documents/pictures/illustration.jpg. In this format the<br /><br />server no longer has any special place in the address, which is simply one coherent<br /><br />hierarchical path.<br /><br /> History<br /><br />History of the World Wide Web<br /><br />This NeXT Computer used by Sir Tim Berners-Lee at CERN became the first Web server.<br /><br />The underlying ideas of the Web can be traced as far back as 1980, when, at CERN in<br /><br />Switzerland, Sir Tim Berners-Lee built ENQUIRE (a reference to Enquire Within Upon<br /><br />Everything, a book he recalled from his youth). While it was rather different from the<br /><br />system in use today, it contained many of the same core ideas (and even some of the<br /><br />ideas of Berners-Lee's next project after the World Wide Web, the Semantic Web).<br /><br />In March 1989, Berners-Lee wrote a proposal[4] which referenced ENQUIRE and<br /><br />described a more elaborate information management system. With help from Robert<br /><br />Cailliau, he published a more formal proposal (on November 12, 1990) to build a<br /><br />"Hypertext project" called "WorldWideWeb" (one word, also "W3")[1] as a "web of<br /><br />nodes" with "hypertext documents" to store data. That data would be viewed in<br /><br />"hypertext pages" (webpages) by various "browsers" (line-mode or full-screen) on the<br /><br />computer network, using an "access protocol" connecting the "Internet and DECnet<br /><br />protocol worlds".[1]<br /><br />The proposal had been modeled after EBT's (Electronic Book Technology, a spin-off<br /><br />from the Institute for Research in Information and Scholarship at Brown University)<br /><br />Dynatext SGML reader that CERN had licensed. The Dynatext system, although<br /><br />technically advanced (a key player in the extension of SGML ISO 8879:1986 to<br /><br />Hypermedia within HyTime), was considered too expensive and with an inappropriate<br /><br />licensing policy for general HEP (High Energy Physics) community use: a fee for each<br /><br />document and each time a document was charged.<br /><br />A NeXT Computer was used by Berners-Lee as the world's first Web server and also to<br /><br />write the first Web browser, WorldWideWeb, in 1990. By Christmas 1990, Berners-Lee<br /><br />had built all the tools necessary for a working Web:[5] the first Web browser (which<br /><br />was a Web editor as well), the first Web server, and the first Web pages[6] which<br /><br />described the project itself.<br /><br />On August 6, 1991, he posted a short summary of the World Wide Web project on the<br /><br />alt.hypertext newsgroup.[7] This date also marked the debut of the Web as a publicly<br /><br />available service on the Internet.<br /><br />The first server outside Europe was set up at SLAC in December 1991 [8].<br /><br />The crucial underlying concept of hypertext originated with older projects from the<br /><br />1960s, such as the Hypertext Editing System (HES) at Brown University--- among<br /><br />others Ted Nelson and Andries van Dam--- Ted Nelson's Project Xanadu and Douglas<br /><br />Engelbart's oN-Line System (NLS). Both Nelson and Engelbart were in turn inspired by<br /><br />Vannevar Bush's microfilm-based "memex," which was described in the 1945 essay "As<br /><br />We May Think".<br /><br />Berners-Lee's breakthrough was to marry hypertext to the Internet. In his book<br /><br />Weaving The Web, he explains that he had repeatedly suggested that a marriage<br /><br />between the two technologies was possible to members of both technical communities,<br /><br />but when no one took up his invitation, he finally tackled the project himself. In the<br /><br />process, he developed a system of globally unique identifiers for resources on the Web<br /><br />and elsewhere: the Uniform Resource Identifier.<br /><br />The World Wide Web had a number of differences from other hypertext systems that<br /><br />were then available. The Web required only unidirectional links rather than bidirectional<br /><br />ones. This made it possible for someone to link to another resource without action by<br /><br />the owner of that resource. It also significantly reduced the difficulty of implementing<br /><br />Web servers and browsers (in comparison to earlier systems), but in turn presented the<br /><br />chronic problem of link rot. Unlike predecessors such as HyperCard, the World Wide<br /><br />Web was non-proprietary, making it possible to develop servers and clients<br /><br />independently and to add extensions without licensing restrictions.<br /><br />On April 30, 1993, CERN announced[9] that the World Wide Web would be free to<br /><br />anyone, with no fees due. Coming two months after the announcement that the Gopher<br /><br />protocol was no longer free to use, this produced a rapid shift away from Gopher and<br /><br />towards the Web. An early popular Web browser was ViolaWWW, which was based<br /><br />upon HyperCard.<br /><br />Scholars generally agree, however, that the turning point for the World Wide Web<br /><br />began with the introduction[10] of the Mosaic Web browser[11] in 1993, a graphical<br /><br />browser developed by a team at the National Center for Supercomputing Applications at<br /><br />the University of Illinois at Urbana-Champaign (NCSA-UIUC), led by Marc Andreessen.<br /><br />Funding for Mosaic came from the High-Performance Computing and Communications<br /><br />Initiative, a funding program initiated by the High Performance Computing and<br /><br />Communication Act of 1991, one of several computing developments initiated by<br /><br />Senator Al Gore.[12] Prior to the release of Mosaic, graphics were not commonly mixed<br /><br />with text in Web pages, and its popularity was less than older protocols in use over the<br /><br />Internet, such as Gopher and Wide Area Information Servers (WAIS). Mosaic's graphical<br /><br />user interface allowed the Web to become, by far, the most popular Internet protocol.<br /><br />The World Wide Web Consortium (W3C) was founded by Tim Berners-Lee after he left<br /><br />the European Organization for Nuclear Research (CERN) in October, 1994. It was<br /><br />founded at the Massachusetts Institute of Technology Laboratory for Computer Science<br /><br />(MIT/LCS) with support from the Defense Advanced Research Projects Agency<br /><br />(DARPA)—which had pioneered the Internet—and the European Commission.<br /><br /> Standards<br />Web standards<br /><br />Many formal standards and other technical specifications define the operation of<br /><br />different aspects of the World Wide Web, the Internet, and computer information<br /><br />exchange. Many of the documents are the work of the World Wide Web Consortium<br /><br />(W3C), headed by Berners-Lee, but some are produced by the Internet Engineering<br /><br />Task Force (IETF) and other organizations.<br /><br />Usually, when Web standards are discussed, the following publications are seen as<br /><br />foundational:<br /><br /> * Recommendations for markup languages, especially HTML and XHTML, from the<br /><br />W3C. These define the structure and interpretation of hypertext documents.<br /> * Recommendations for stylesheets, especially CSS, from the W3C.<br /> * Standards for ECMAScript (usually in the form of JavaScript), from Ecma<br /><br />International.<br /> * Recommendations for the Document Object Model, from W3C.<br /><br />Additional publications provide definitions of other essential technologies for the World<br /><br />Wide Web, including, but not limited to, the following:<br /><br /> * Uniform Resource Identifier (URI), which is a universal system for referencing<br /><br />resources on the Internet, such as hypertext documents and images. URIs, often called<br /><br />URLs, are defined by the IETF's RFC 3986 / STD 66: Uniform Resource Identifier (URI):<br /><br />Generic Syntax, as well as its predecessors and numerous URI scheme-defining RFCs;<br /> * HyperText Transfer Protocol (HTTP), especially as defined by RFC 2616: http://1.1<br /><br />and RFC 2617: HTTP Authentication, which specify how the browser and server<br /><br />authenticate each other.<br /><br /> Privacy<br /><br />Computer users, who save time and money, and who gain conveniences and<br /><br />entertainment, may or may not have surrendered the right to privacy in exchange for<br /><br />using a number of technologies including the Web.[13] Worldwide, more than a half<br /><br />billion people have used a social network service,[14] and of Americans who grew up<br /><br />with the Web, half created an online profile[15] and are part of a generational shift<br /><br />that could be changing norms.[16][17] Among services paid for by advertising, Yahoo!<br /><br />could collect the most data about users of commercial websites, about 2,500 bits of<br /><br />information per month about each typical user of its site and its affiliated advertising<br /><br />network sites. Yahoo! was followed by MySpace with about half that potential and then<br /><br />by AOL-TimeWarner, Google, Facebook, Microsoft, and eBay.[18]<br /><br />Privacy representatives from 60 countries have resolved to ask for laws to complement<br /><br />industry self-regulation, for education for children and other minors who use the Web,<br /><br />and for default protections for users of social networks.[19] They also believe data<br /><br />protection for personally identifiable information benefits business more than the sale<br /><br />of that information.[19] Users can opt-in to features in browsers from companies such<br /><br />as Apple, Google, Microsoft (beta) and Mozilla (beta) to clear their personal histories<br /><br />locally and block some cookies and advertising networks[20] but they are still tracked<br /><br />in websites' server logs.[citation needed] Berners-Lee and colleagues see hope in<br /><br />accountability and appropriate use achieved by extending the Web's architecture to<br /><br />policy awareness, perhaps with audit logging, reasoners and appliances.[21]<br /><br /> Security<br /><br />The Web has become criminals' preferred pathway for spreading malware. Cybercrime<br /><br />carried out on the Web can include identity theft, fraud, espionage and intelligence<br /><br />gathering.[22] Web-based vulnerabilities now outnumber traditional computer security<br /><br />concerns,[23] and as measured by Google, about one in ten Web pages may contain<br /><br />malicious code.[24] Most Web-based attacks take place on legitimate websites, and<br /><br />most, as measured by Sophos, are hosted in the United States, China and Russia.[25]<br /><br />The most common of all malware threats is SQL injection attacks against websites.[26]<br /><br />Through HTML and URIs the Web was vulnerable to attacks like cross-site scripting<br /><br />(XSS) that came with the introduction of JavaScript[27] and were exacerbated to some<br /><br />degree by Web 2.0 and Ajax web design that favors the use of scripts.[28] Today by<br /><br />one estimate, 70% of all websites are open to XSS attacks on their users.[29]<br /><br />Proposed solutions vary to extremes. Large security vendors like McAfee already design<br /><br />governance and compliance suites to meet post-9/11 regulations,[30] and some, like<br /><br />Finjan have recommended active real-time inspection of code and all content regardless<br /><br />of its source.[22] Some have argued that for enterprise to see security as a business<br /><br />opportunity rather than a cost center,[31] "ubiquitous, always-on digital rights<br /><br />management" enforced in the infrastructure by a handful of organizations must replace<br /><br />the hundreds of companies that today secure data and networks.[32] Jonathan Zittrain<br /><br />has said users sharing responsibility for computing safety is far preferable to locking<br /><br />down the Internet.[33]<br /><br />Web accessibility<br /><br />Many countries regulate web accessibility as a requirement for web sites.<br /><br /> Java<br /><br />A significant advance in Web technology was Sun Microsystems' Java platform. It<br /><br />enables Web pages to embed small programs (called applets) directly into the view.<br /><br />These applets run on the end-user's computer, providing a richer user interface than<br /><br />simple Web pages. Java client-side applets never gained the popularity that Sun had<br /><br />hoped for a variety of reasons, including lack of integration with other content (applets<br /><br />were confined to small boxes within the rendered page) and the fact that many<br /><br />computers at the time were supplied to end users without a suitably installed Java<br /><br />Virtual Machine, and so required a download by the user before applets would appear.<br /><br />Adobe Flash now performs many of the functions that were originally envisioned for<br /><br />Java applets, including the playing of video content, animation, and some rich GUI<br /><br />features. Java itself has become more widely used as a platform and language for<br /><br />server-side and other programming.<br /><br /> JavaScript<br /><br />JavaScript, on the other hand, is a scripting language that was initially developed for<br /><br />use within Web pages. The standardized version is ECMAScript. While its name is<br /><br />similar to Java, JavaScript was developed by Netscape and has very little to do with<br /><br />Java, although the syntax of both languages is derived from the C programming<br /><br />language. In conjunction with a Web page's Document Object Model (DOM), JavaScript<br /><br />has become a much more powerful technology than its creators originally<br /><br />envisioned.[citation needed] The manipulation of a page's DOM after the page is<br /><br />delivered to the client has been called Dynamic HTML (DHTML), to emphasize a shift<br /><br />away from static HTML displays.<br /><br />In simple cases, all the optional information and actions available on a<br /><br />JavaScript-enhanced Web page will have been downloaded when the page was first<br /><br />delivered. Ajax ("Asynchronous JavaScript and XML") is a group of interrelated web<br /><br />development techniques used for creating interactive web applications that provide a<br /><br />method whereby parts within a Web page may be updated, using new information<br /><br />obtained over the network at a later time in response to user actions. This allows the<br /><br />page to be more responsive, interactive and interesting, without the user having to<br /><br />wait for whole-page reloads. Ajax is seen as an important aspect of what is being<br /><br />called Web 2.0. Examples of Ajax techniques currently in use can be seen in Gmail,<br /><br />Google Maps, and other dynamic Web applications.<br /><br /> Publishing Web pages<br /><br />Web page production is available to individuals outside the mass media. In order to<br /><br />publish a Web page, one does not have to go through a publisher or other media<br /><br />institution, and potential readers could be found in all corners of the globe.<br /><br />Many different kinds of information are available on the Web, and for those who wish<br /><br />to know other societies, cultures, and peoples, it has become easier.<br /><br />The increased opportunity to publish materials is observable in the countless personal<br /><br />and social networking pages, as well as sites by families, small shops, etc., facilitated<br /><br />by the emergence of free Web hosting services.<br /><br /> Statistics<br /><br />According to a 2001 study, there were massively more than 550 billion documents on<br /><br />the Web, mostly in the invisible Web, or deep Web.[34] A 2002 survey of 2,024 million<br /><br />Web pages[35] determined that by far the most Web content was in English: 56.4%;<br /><br />next were pages in German (7.7%), French (5.6%), and Japanese (4.9%). A more<br /><br />recent study, which used Web searches in 75 different languages to sample the Web,<br /><br />determined that there were over 11.5 billion Web pages in the publicly indexable Web<br /><br />as of the end of January 2005.[36] As of June 2008, the indexable web contains at<br /><br />least 63 billion pages.[37] On July 25, 2008, Google software engineers Jesse Alpert<br /><br />and Nissan Hajaj announced that Google Search had discovered one trillion unique<br /><br />URLs.[38]<br /><br />Over 100.1 million websites operated as of March 2008.[39] Of these 74% were<br /><br />commercial or other sites operating in the .com generic top-level domain.[39]<br /><br /> Speed issues<br /><br />Frustration over congestion issues in the Internet infrastructure and the high latency<br /><br />that results in slow browsing has led to an alternative, pejorative name for the World<br /><br />Wide Web: the World Wide Wait.[citation needed] Speeding up the Internet is an<br /><br />ongoing discussion over the use of peering and QoS technologies. Other solutions to<br /><br />reduce the World Wide Wait can be found on W3C.<br /><br />Standard guidelines for ideal Web response times are:[40]<br /><br /> * 0.1 second (one tenth of a second). Ideal response time. The user doesn't sense<br /><br />any interruption.<br /> * 1 second. Highest acceptable response time. Download times above 1 second<br /><br />interrupt the user experience.<br /> * 10 seconds. Unacceptable response time. The user experience is interrupted and<br /><br />the user is likely to leave the site or system.<br /><br />These numbers are useful for planning server capacity.<br /><br /> Caching<br /><br />If a user revisits a Web page after only a short interval, the page data may not need to<br /><br />be re-obtained from the source Web server. Almost all Web browsers cache<br /><br />recently-obtained data, usually on the local hard drive. HTTP requests sent by a<br /><br />browser will usually only ask for data that has changed since the last download. If the<br /><br />locally-cached data are still current, it will be reused.<br /><br />Caching helps reduce the amount of Web traffic on the Internet. The decision about<br /><br />expiration is made independently for each downloaded file, whether image, stylesheet,<br /><br />JavaScript, HTML, or whatever other content the site may provide. Thus even on sites<br /><br />with highly dynamic content, many of the basic resources only need to be refreshed<br /><br />occasionally. Web site designers find it worthwhile to collate resources such as CSS<br /><br />data and JavaScript into a few site-wide files so that they can be cached efficiently.<br /><br />This helps reduce page download times and lowers demands on the Web server.<br /><br />There are other components of the Internet that can cache Web content. Corporate and<br /><br />academic firewalls often cache Web resources requested by one user for the benefit of<br /><br />all. (See also Caching proxy server.) Some search engines, such as Google or Yahoo!,<br /><br />also store cached content from websites.<br /><br />Apart from the facilities built into Web servers that can determine when files have<br /><br />been updated and so need to be re-sent, designers of dynamically-generated Web<br /><br />pages can control the HTTP headers sent back to requesting users, so that transient or<br /><br />sensitive pages are not cached. Internet banking and news sites frequently use this<br /><br />facility.<br /><br />Data requested with an HTTP 'GET' is likely to be cached if other conditions are met;<br /><br />data obtained in response to a 'POST' is assumed to depend on the data that was<br /><br />POSTed and so is not cached.<br /><br /> Link rot and Web archival<br /><br /> Main article: Link rot<br /><br />Over time, many Web resources pointed to by hyperlinks disappear, relocate, or are<br /><br />replaced with different content. This phenomenon is referred to in some circles as "link<br /><br />rot" and the hyperlinks affected by it are often called "dead links".<br /><br />The ephemeral nature of the Web has prompted many efforts to archive Web sites. The<br /><br />Internet Archive is one of the most well-known efforts; it has been active since 1996.<br /><br /> Academic conferences<br /><br />The major academic event covering the Web is the World Wide Web Conference,<br /><br />promoted by IW3C2.<br /><br /> WWW prefix in Web addresses<br /><br />The letters "www" are commonly found at the beginning of Web addresses because of<br /><br />the long-standing practice of naming Internet hosts (servers) according to the services<br /><br />they provide. So for example, the host name for a Web server is often "www"; for an<br /><br />FTP server, "ftp"; and for a USENET news server, "news" or "nntp" (after the news<br /><br />protocol NNTP). These host names appear as DNS subdomain names, as in<br /><br />"www.mrfweb.we.bs".<br /><br />This use of such prefixes is not required by any technical standard; indeed, the first<br /><br />Web server was at "nxoc01.cern.ch",[41] and even today many Web sites exist without<br /><br />a "www" prefix. The "www" prefix has no meaning in the way the main Web site is<br /><br />shown. The "www" prefix is simply one choice for a Web site's host name.<br /><br />However, some website addresses require the www. prefix, and if typed without one,<br /><br />won't work; there are also some which must be typed without the prefix. Sites that do<br /><br />not have Host Headers properly setup are the cause of this. Some hosting companies<br /><br />do not setup a www or @ A record in the web server configuration and/or at the DNS<br /><br />server level.<br /><br />Some Web browsers will automatically try adding "www." to the beginning, and<br /><br />possibly ".com" to the end, of typed URLs if no host is found without them. All major<br /><br />web browsers will also prefix "http://www.mrfweb.we.bs/" and append ".com" to the<br /><br />address bar contents if the Control and Enter keys are pressed simultaneously. For<br /><br />example, entering "example" in the address bar and then pressing either Enter or<br /><br />Control+Enter will usually resolve to "http://www.mrfweb.we.bs", depending on the<br /><br />exact browser version and its settings.<br /><a href="http://webmanagementindia.blogspot.com/" target="_perent">Web Management India</a><br /><a href="http://websolutiontools.blogspot.com/" target="_perent">Web Solution Tools.</a><br /><a href="http://wrfwebdesign.blogspot.com/" target="_perent">Mrf Web Design</a><br /><a href="http://webmanagementindia.blogspot.com/"></a><a href="http://mrfdesign.we.bs/index.htm" target="_perent">Mrf Web Development</a><br /><a href="http://mrfdesign.we.bs/index.htm" target="_perent">Mrf Web Development</a>Raj Vaishnawhttp://www.blogger.com/profile/04513071956356747186noreply@blogger.com0tag:blogger.com,1999:blog-2629130971807160423.post-51828191729917585142009-01-10T11:13:00.000-08:002009-01-30T04:02:28.974-08:00Web server1. HTTP: every web server program operates by accepting HTTP requests from the<br /><br />client, and providing an HTTP response to the client. The HTTP response usually<br /><br />consists of an HTML document, but can also be a raw file, an image, or some other<br /><br />type of document (defined by MIME-types). If some error is found in client request or<br /><br />while trying to serve it, a web server has to send an error response which may include<br /><br />some custom HTML or text messages to better explain the problem to end users.<br /> 2. Logging: usually web servers have also the capability of logging some detailed<br /><br />information, about client requests and server responses, to log files; this allows the<br /><br />webmaster to collect statistics by running log analyzers on these files.<br /><br />In practice many web servers implement the following features also:<br /><br /> 1. Authentication, optional authorization request (request of user name and<br /><br />password) before allowing access to some or all kind of resources.<br /> 2. Handling of static content (file content recorded in server's filesystem(s)) and<br /><br />dynamic content by supporting one or more related interfaces (SSI, CGI, SCGI, FastCGI,<br /><br />JSP, PHP, ASP, ASP.NET, Server API such as NSAPI, ISAPI, etc.).<br /> 3. HTTPS support (by SSL or TLS) to allow secure (encrypted) connections to the<br /><br />server on the standard port 443 instead of usual port 80.<br /> 4. Content compression (i.e. by gzip encoding) to reduce the size of the responses<br /><br />(to lower bandwidth usage, etc.).<br /> 5. Virtual hosting to serve many web sites using one IP address.<br /> 6. Large file support to be able to serve files whose size is greater than 2 GB on 32<br /><br />bit OS.<br /> 7. Bandwidth throttling to limit the speed of responses in order to not saturate the<br /><br />network and to be able to serve more clients.<br /><br />Origin of returned content<br /><br />The origin of the content sent by server is called:<br /><br /> * static if it comes from an existing file lying on a filesystem;<br /> * dynamic if it is dynamically generated by some other program or script or<br /><br />application programming interface (API) called by the web server.<br /><br />Serving static content is usually much faster (from 2 to 100 times) than serving<br /><br />dynamic content, especially if the latter involves data pulled from a database.<br /><br />Path translation<br /><br />Web servers are able to map the path component of a Uniform Resource Locator (URL)<br /><br />into:<br /><br /> * a local file system resource (for static requests);<br /> * an internal or external program name (for dynamic requests).<br /><br />For a static request the URL path specified by the client is relative to the Web server's<br /><br />root directory.<br /><br />Consider the following URL as it would be requested by a client:<br /><br />http://www.mrfweb.we.bs/index.html<br /><br />The client's web browser will translate it into a connection to www.example.com with<br /><br />the following HTTP 1.1 request:<br /><br />GET /path/file.html HTTP/1.1<br />Host: www.mrfweb.we.bs<br /><br />The web server on www.mrfweb.we.bs will append the given path to the path of its<br /><br />root directory. On Unix machines, this is commonly /var/www. The result is the local<br /><br />file system resource:<br /><br />/var/www/path/file.html<br /><br />The web server will then read the file, if it exists, and send a response to the client's<br /><br />web browser. The response will describe the content of the file and contain the file<br /><br />itself. ..........<br /><br />Load limits<br /><br />A web server (program) has defined load limits, because it can handle only a limited<br /><br />number of concurrent client connections (usually between 2 and 60,000, by default<br /><br />between 500 and 1,000) per IP address (and TCP port) and it can serve only a certain<br /><br />maximum number of requests per second depending on:<br /><br /> * its own settings;<br /> * the HTTP request type;<br /> * content origin (static or dynamic);<br /> * the fact that the served content is or is not cached;<br /> * the hardware and software limits of the OS where it is working.<br /><br />When a web server is near to or over its limits, it becomes overloaded and thus<br /><br />unresponsive.<br /><br />Overload causes<br />A daily graph of a web server's load, indicating a spike in the load early in the day.<br /><br />At any time web servers can be overloaded because of:<br /><br /> * Too much legitimate web traffic (i.e. thousands or even millions of clients hitting<br /><br />the web site in a short interval of time. e.g. Slashdot effect);<br /> * DDoS (Distributed Denial of Service) attacks;<br /> * Computer worms that sometimes cause abnormal traffic because of millions of<br /><br />infected computers (not coordinated among them);<br /> * XSS viruses can cause high traffic because of millions of infected browsers and/or<br /><br />web servers;<br /> * Internet web robots traffic not filtered/limited on large web sites with very few<br /><br />resources (bandwidth, etc.);<br /> * Internet (network) slowdowns, so that client requests are served more slowly and<br /><br />the number of connections increases so much that server limits are reached;<br /> * Web servers (computers) partial unavailability, this can happen because of<br /><br />required or urgent maintenance or upgrade, HW or SW failures, back-end (i.e. DB)<br /><br />failures, etc.; in these cases the remaining web servers get too much traffic and<br /><br />become overloaded.<br /><br />Overload symptoms<br /><br />The symptoms of an overloaded web server are:<br /><br /> * requests are served with (possibly long) delays (from 1 second to a few hundred<br /><br />seconds);<br /> * 500, 502, 503, 504 HTTP errors are returned to clients (sometimes also unrelated<br /><br />404 error or even 408 error may be returned);<br /> * TCP connections are refused or reset (interrupted) before any content is sent to<br /><br />clients;<br /> * in very rare cases, only partial contents are sent (but this behavior may well be<br /><br />considered a bug, even if it usually depends on unavailable system resources).<br /><br />Anti-overload techniques<br /><br />To partially overcome above load limits and to prevent overload, most popular web<br /><br />sites use common techniques like:<br /><br /> * managing network traffic, by using:<br /> o Firewalls to block unwanted traffic coming from bad IP sources or having bad<br /><br />patterns;<br /> o HTTP traffic managers to drop, redirect or rewrite requests having bad HTTP<br /><br />patterns;<br /> o Bandwidth management and traffic shaping, in order to smooth down peaks in<br /><br />network usage;<br /> * deploying web cache techniques;<br /> * using different domain names to serve different (static and dynamic) content by<br /><br />separate Web servers, i.e.:<br /> o<br /><br /> http://images.mrfweb.we.bs/<br /> o<br /><br /> http://www.mrfweb.we.bs/<br /><br /> * using different domain names and/or computers to separate big files from small<br /><br />and medium sized files; the idea is to be able to fully cache small and medium sized<br /><br />files and to efficiently serve big or huge (over 10 - 1000 MB) files by using different<br /><br />settings;<br /> * using many Web servers (programs) per computer, each one bound to its own<br /><br />network card and IP address;<br /> * using many Web servers (computers) that are grouped together so that they act or<br /><br />are seen as one big Web server, see also: Load balancer;<br /> * adding more hardware resources (i.e. RAM, disks) to each computer;<br /> * tuning OS parameters for hardware capabilities and usage;<br /> * using more efficient computer programs for web servers, etc.;<br /> * using other workarounds, especially if dynamic content is involved.<br /><br />Historical notes<br />The world's first web server.<br /><br />In 1989 Tim Berners-Lee proposed to his employer CERN (European Organization for<br /><br />Nuclear Research) a new project, which had the goal of easing the exchange of<br /><br />information between scientists by using a hypertext system. As a result of the<br /><br />implementation of this project, in 1990 Berners-Lee wrote two programs:<br /><br /> * a browser called WorldWideWeb;<br /> * the world's first web server, later known as CERN HTTPd, which ran on NeXTSTEP.<br /><br />Between 1991 and 1994 the simplicity and effectiveness of early technologies used to<br /><br />surf and exchange data through the World Wide Web helped to port them to many<br /><br />different operating systems and spread their use among lots of different social groups<br /><br />of people, first in scientific organizations, then in universities and finally in industry.<br /><br />In 1994 Tim Berners-Lee decided to constitute the World Wide Web Consortium to<br /><br />regulate the further development of the many technologies involved (HTTP, HTML, etc.)<br /><br />through a standardization process.<br /><br />The following years are recent history which has seen an exponential growth of the<br /><br />number of web sites and servers.<br /><br />Market structure<br /><br />Given below is a list of top Web server software vendors published in a Netcraft survey<br /><br />in September 2008.<br />Vendor Product Web Sites Hosted Percent<br />Apache Apache 91,068,713 50.24%<br />Microsoft IIS 62,364,634 34.4%<br />Google GWS 10,072,687 5.56%<br />lighttpd lighttpd 3,095,928 1.71%<br />nginx nginx 2,562,554 1.41%<br />Oversee Oversee 1,938,953 1.07%<br />Others - 10,174,366 5.61%<br />Total - 181,277,835 100.00%<br /><br /><br /><a href="http://webmanagementindia.blogspot.com/" target="_perent">Web Management India</a><br /><a href="http://websolutiontools.blogspot.com/" target="_perent">Web Solution Tools.</a><br /><a href="http://wrfwebdesign.blogspot.com/" target="_perent">Mrf Web Design</a><br /><a href="http://webdesigndevlopment.blogspot.com/"></a><a href="http://mrfdesign.we.bs/index.htm" target="_perent">Mrf Web Development</a><br /><a href="http://mrfdesign.we.bs/index.htm" target="_perent">Mrf Web Development</a>Raj Vaishnawhttp://www.blogger.com/profile/04513071956356747186noreply@blogger.com0tag:blogger.com,1999:blog-2629130971807160423.post-77877664141585616412009-01-10T11:12:00.000-08:002009-01-30T04:10:08.865-08:00Modern programmingQuality requirements<br /><br />Whatever the approach to software development may be, the final program must<br /><br />satisfy some fundamental properties. The following five properties are among the most<br /><br />relevant:<br /><br /> * Efficiency/Performance: the amount of system resources a program consumes<br /><br />(processor time, memory space, slow devices, network bandwidth and to some extent<br /><br />even user interaction), the less the better.<br /> * Reliability: how often the results of a program are correct. This depends on<br /><br />prevention of error propagation resulting from data conversion and prevention of errors<br /><br />resulting from buffer overflows, underflows and zero division.<br /> * Robustness: how well a program anticipates situations of data type conflict and<br /><br />other incompatibilities that result in run time errors and program halts. The focus is<br /><br />mainly on user interaction and the handling of exceptions.<br /> * Usability: the clarity and intuitiveness of a programs output can make or break its<br /><br />success. This involves a wide range of textual and graphical elements that makes a<br /><br />program easy and comfortable to use.<br /> * Portability: the range of computer hardware and operating system platforms on<br /><br />which the source code of a program can be compiled/interpreted and run. This depends<br /><br />mainly on the range of platform specific compilers for the language of the source code<br /><br />rather than anything having to do with the program directly.<br /><br /> Algorithmic complexity<br /><br />The academic field and the engineering practice of computer programming are both<br /><br />largely concerned with discovering and implementing the most efficient algorithms for a<br /><br />given class of problem. For this purpose, algorithms are classified into orders using<br /><br />so-called Big O notation, O(n), which expresses resource use, such as execution time<br /><br />or memory consumption, in terms of the size of an input. Expert programmers are<br /><br />familiar with a variety of well-established algorithms and their respective complexities<br /><br />and use this knowledge to choose algorithms that are best suited to the circumstances.<br /><br /> Methodologies<br /><br />The first step in most formal software development projects is requirements analysis,<br /><br />followed by testing to determine value modeling, implementation, and failure<br /><br />elimination (debugging). There exist a lot of differing approaches for each of those<br /><br />tasks. One approach popular for requirements analysis is Use Case analysis.<br /><br />Popular modeling techniques include Object-Oriented Analysis and Design (OOAD) and<br /><br />Model-Driven Architecture (MDA). The Unified Modeling Language (UML) is a notation<br /><br />used for both OOAD and MDA.<br /><br />A similar technique used for database design is Entity-Relationship Modeling (ER<br /><br />Modeling).<br /><br />Implementation techniques include imperative languages (object-oriented or<br /><br />procedural), functional languages, and logic languages.<br /><br /> Measuring language usage<br /><br />It is very difficult to determine what are the most popular of modern programming<br /><br />languages. Some languages are very popular for particular kinds of applications (e.g.,<br /><br />COBOL is still strong in the corporate data center, often on large mainframes, FORTRAN<br /><br />in engineering applications, and C in embedded applications), while some languages<br /><br />are regularly used to write many different kinds of applications.<br /><br />Methods of measuring language popularity include: counting the number of job<br /><br />advertisements that mention the language[7], the number of books teaching the<br /><br />language that are sold (this overestimates the importance of newer languages), and<br /><br />estimates of the number of existing lines of code written in the language (this<br /><br />underestimates the number of users of business languages such as COBOL).<br /><br /> Debugging<br />A bug which was debugged in 1947.<br /><br />Debugging is a very important task in the software development process, because an<br /><br />erroneous program can have significant consequences for its users. Some languages are<br /><br />more prone to some kinds of faults because their specification does not require<br /><br />compilers to perform as much checking as other languages. Use of a static analysis tool<br /><br />can help detect some possible problems.<br /><br />Debugging is often done with IDEs like Visual Studio, NetBeans, and Eclipse.<br /><br />Standalone debuggers like gdb are also used, and these often provide less of a visual<br /><br />environment, usually using a command line.<br /><br /> Programming languages<br /><br /> Main articles: Programming language and List of programming languages<br /><br />Different programming languages support different styles of programming (called<br /><br />programming paradigms). The choice of language used is subject to many<br /><br />considerations, such as company policy, suitability to task, availability of third-party<br /><br />packages, or individual preference. Ideally, the programming language best suited for<br /><br />the task at hand will be selected. Trade-offs from this ideal involve finding enough<br /><br />programmers who know the language to build a team, the availability of compilers for<br /><br />that language, and the efficiency with which programs written in a given language<br /><br />execute.<br /><br />Allen Downey, in his book How To Think Like A Computer Scientist, writes:<br /><br /> The details look different in different languages, but a few basic instructions appear<br /><br />in just about every language: input: Get data from the keyboard, a file, or some other<br /><br />device. output: Display data on the screen or send data to a file or other device. math:<br /><br />Perform basic mathematical operations like addition and multiplication. conditional<br /><br />execution: Check for certain conditions and execute the appropriate sequence of<br /><br />statements. repetition: Perform some action repeatedly, usually with some variation.<br /><br />Many computer languages provide a mechanism to call functions provided by libraries.<br /><br />Provided the functions in a library follow the appropriate runtime conventions (eg,<br /><br />method of passing arguments), then these functions may be written in any other<br /><br />language.<br /><br /><a href="http://webmanagementindia.blogspot.com/" target="_perent">Web Management India</a><br /><a href="http://websolutiontools.blogspot.com/" target="_perent">Web Solution Tools.</a><br /><a href="http://wrfwebdesign.blogspot.com/" target="_perent">Mrf Web Design</a><br /><a href="http://webdesigndevlopment.blogspot.com/"></a><a href="http://mrfdesign.we.bs/index.htm" target="_perent">Mrf Web Development</a><br /><a href="http://mrfdesign.we.bs/index.htm" target="_perent">Mrf Web Development</a>Raj Vaishnawhttp://www.blogger.com/profile/04513071956356747186noreply@blogger.com0tag:blogger.com,1999:blog-2629130971807160423.post-2243107002760918092009-01-10T11:11:00.000-08:002009-01-30T04:11:15.069-08:00Computer ProgrammingComputer programming (often shortened to programming or coding) is the process of<br /><br />writing, testing, debugging/troubleshooting, and maintaining the source code of<br /><br />computer programs. This source code is written in a programming language. The code<br /><br />may be a modification of an existing source or something completely new. The purpose<br /><br />of programming is to create a program that exhibits a certain desired behavior<br /><br />(customization). The process of writing source code often requires expertise in many<br /><br />different subjects, including knowledge of the application domain, specialized<br /><br />algorithms and formal logic.<br />Overview<br /><br />Within software engineering, programming (the implementation) is regarded as one<br /><br />phase in a software development process.<br /><br />There is an ongoing debate on the extent to which the writing of programs is an art, a<br /><br />craft or an engineering discipline.[1] Good programming is generally considered to be<br /><br />the measured application of all three, with the goal of producing an efficient and<br /><br />evolvable software solution (the criteria for "efficient" and "evolvable" vary<br /><br />considerably). The discipline differs from many other technical professions in that<br /><br />programmers generally do not need to be licensed or pass any standardized (or<br /><br />governmentally regulated) certification tests in order to call themselves "programmers"<br /><br />or even "software engineers." However, representing oneself as a "Professional<br /><br />Software Engineer" without a license from an accredited institution is illegal in many<br /><br />parts of the world.<br /><br />Another ongoing debate is the extent to which the programming language used in<br /><br />writing computer programs affects the form that the final program takes. This debate is<br /><br />analogous to that surrounding the Sapir-Whorf hypothesis [2] in linguistics, that<br /><br />postulates that a particular language's nature influences the habitual thought of its<br /><br />speakers. Different language patterns yield different patterns of thought. This idea<br /><br />challenges the possibility of representing the world perfectly with language, because it<br /><br />acknowledges that the mechanisms of any language condition the thoughts of its<br /><br />speaker community.<br /><br />Said another way, programming is the craft of transforming requirements into<br /><br />something that a computer can execute.<br /><br /> History of programming<br /><br /> See also: History of programming languages<br /><br />Wired plug board for an IBM 402 Accounting Machine.<br /><br />The concept of devices that operate following a pre-defined set of instructions traces<br /><br />back to Greek Mythology, notably Hephaestus and his mechanical servants[3]. The<br /><br />Antikythera mechanism was a calculater utilizing gears of various sizes and<br /><br />configuration to determine its operation. The earliest known programmable machines<br /><br />(machines whose behavior can be controlled and predicted with a set of instructions)<br /><br />were Al-Jazari's programmable Automata in 1206.[4] One of Al-Jazari's robots was<br /><br />originally a boat with four automatic musicians that floated on a lake to entertain<br /><br />guests at royal drinking parties. Programming this mechanism's behavior meant placing<br /><br />pegs and cams into a wooden drum at specific locations. These would then bump into<br /><br />little levers that operate a percussion instrument. The output of this device was a<br /><br />small drummer playing various rhythms and drum patterns.[5][6] Another sophisticated<br /><br />programmable machine by Al-Jazari was the castle clock, notable for its concept of<br /><br />variables which the operator could manipulate as necessary (i.e. the length of day and<br /><br />night). The Jacquard Loom, which Joseph Marie Jacquard developed in 1801, uses a<br /><br />series of pasteboard cards with holes punched in them. The hole pattern represented<br /><br />the pattern that the loom had to follow in weaving cloth. The loom could produce<br /><br />entirely different weaves using different sets of cards. Charles Babbage adopted the<br /><br />use of punched cards around 1830 to control his Analytical Engine. The synthesis of<br /><br />numerical calculation, predetermined operation and output, along with a way to<br /><br />organize and input instructions in a manner relatively easy for humans to conceive and<br /><br />produce, led to the modern development of computer programming.<br /><br />Development of computer programming accelerated through the Industrial Revolution.<br /><br />The punch card innovation was later refined by Herman Hollerith who, in 1896 founded<br /><br />the Tabulating Machine Company (which became IBM). He invented the Hollerith<br /><br />punched card, the card reader, and the key punch machine. These inventions were the<br /><br />foundation of the modern information processing industry. The addition of a plug-board<br /><br />to his 1906 Type I Tabulator allowed it to do different jobs without having to be<br /><br />physically rebuilt. By the late 1940s there were a variety of plug-board programmable<br /><br />machines, called unit record equipment, to perform data processing tasks (card<br /><br />reading). Early computer programmers used plug-boards for the variety of complex<br /><br />calculations requested of the newly invented machines.<br />Data and instructions could be stored on external punch cards, which were kept in order<br /><br />and arranged in program decks.<br /><br />The invention of the Von Neumann architecture allowed computer programs to be<br /><br />stored in computer memory. Early programs had to be painstakingly crafted using the<br /><br />instructions of the particular machine, often in binary notation. Every model of<br /><br />computer would be likely to need different instructions to do the same task. Later<br /><br />assembly languages were developed that let the programmer specify each instruction in<br /><br />a text format, entering abbreviations for each operation code instead of a number and<br /><br />specifying addresses in symbolic form (e.g. ADD X, TOTAL). In 1954 Fortran, the first<br /><br />higher level programming language, was invented. This allowed programmers to specify<br /><br />calculations by entering a formula directly (e.g. Y = X*2 + 5*X + 9). The program text,<br /><br />or source, was converted into machine instructions using a special program called a<br /><br />compiler. Many other languages were developed, including ones for commercial<br /><br />programming, such as COBOL. Programs were mostly still entered using punch cards or<br /><br />paper tape. (See computer programming in the punch card era). By the late 1960s, data<br /><br />storage devices and computer terminals became inexpensive enough so programs could<br /><br />be created by typing directly into the computers. Text editors were developed that<br /><br />allowed changes and corrections to be made much more easily than with punch cards.<br /><br />As time has progressed, computers have made giant leaps in the area of processing<br /><br />power. This has brought about newer programming languages that are more abstracted<br /><br />from the underlying hardware. Although these more abstracted languages require<br /><br />additional overhead, in most cases the huge increase in speed of modern computers<br /><br />has brought about little performance decrease compared to earlier counterparts. The<br /><br />benefits of these more abstracted languages is that they allow both an easier learning<br /><br />curve for people less familiar with the older lower-level programming languages, and<br /><br />they also allow a more experienced programmer to develop simple applications quickly.<br /><br />Despite these benefits, large complicated programs, and programs that are more<br /><br />dependent on speed still require the faster and relatively lower-level languages with<br /><br />today's hardware. (The same concerns were raised about the original Fortran language.)<br /><br />Throughout the second half of the twentieth century, programming was an attractive<br /><br />career in most developed countries. Some forms of programming have been increasingly<br /><br />subject to offshore outsourcing (importing software and services from other countries,<br /><br />usually at a lower wage), making programming career decisions in developed countries<br /><br />more complicated, while increasing economic opportunities in less developed areas. It<br /><br />is unclear how far this trend will continue and how deeply it will impact programmer<br /><br />wages and opportunities.<br /><a href="http://webmanagementindia.blogspot.com/" target="_perent">Web Management India</a><br /><a href="http://websolutiontools.blogspot.com/" target="_perent">Web Solution Tools.</a><br /><a href="http://wrfwebdesign.blogspot.com/" target="_perent">Mrf Web Design</a><br /><a href="http://webdesigndevlopment.blogspot.com/"></a><a href="http://mrfdesign.we.bs/index.htm" target="_perent">Mrf Web Development</a><br /><a href="http://mrfdesign.we.bs/index.htm" target="_perent">Mrf Web Development</a>Raj Vaishnawhttp://www.blogger.com/profile/04513071956356747186noreply@blogger.com0
