Test-driven development and unit tests are the latest way to make sure your code is behaving as you expect through changes and refactoring. Find out how to unit test your PHP code at the module, database, and user interface (UI) level.
Anybody who hasn't done a usability study desperately needs to. No one knows yet how to design the perfect user interface, so even simple do-it-yourself studies often show you serious problems.
This document is an appendix to the W3C "Web Content Accessibility Guidelines 1.0". It provides a list of all checkpoints from the Web Content Accessibility Guidelines 1.0, organized by concept, as a checklist for Web content developers.
A multi-screen GUI has become a favourite amongst designers aiming at a wider and less experienced user community. It is widely held that multiple overlapping windows can be confusing and visually cluttered for the novice user. Another common motivation is that a predominantly data intensive business application must provide simple, fast and by implication 'a-modal' navigation across large sections of the problem domain. This is a common requirement when user task analysis and interviews indicate that the user is often interrupted or must frequently switch between incomplete tasks. It is also common to prefer an a-modal design when it is impossible to predict in advance what the user will prefer to view and when. Particularly true of applications for the World Wide Web where the user community can be unknown or undefined and prior research into their needs and preferences has not been done. It is proposed to provide a single (almost) full screen presentation of a single view, whilst allowing the user to quickly navigate to other related data through no more than two mouse clicks / navigation choices or selections.
Sooner or later, most web designers will be called upon to create an internal site. And will quickly learn that one's own company can be tougher to deal with than any client. Dave Linabury offers tips on surviving the process (and building something good in spite of it).
New research with users aged 3–12 shows that older kids have gained substantial Web proficiency since our last studies, while younger kids still face many problems. Designing for children requires distinct usability approaches, including targeting content narrowly for different ages of kids.
Introduces the breadth of decision-making required in EPSS design. Explores choices and challenges facing designers in the design process, performance cycle, technology constraints, use of storytelling techniques, evaluation, and success factors.
A case study of the Unidata Program Center’s efforts to move information into online formats on the World Wide Web. Types of documents placed on line are discussed, as is the appropriateness of the medium for those documents. The conversion process is looked at. Obstacles to placing information online are also reviewed.
The technique of using CSS to replace normal HTML text, mostly for headings, with a background image in order to achieve a particular look has been talked about many, many times since early 2003.Several different image replacement methods have been proposed, each with their pros and cons. Some methods create accessibility problems, while others place restrictions on the type of image you can use or force you to use extraneous markup. No method that I am aware of is perfect.
Numerous surveys across a diverse range of IT projects have identified that the lack of support from senior management (project sponsorship) is one of the biggest causes of project failure. This briefing explores the need for a project sponsor, the role they need to play, and how to choose one.
The Web-surfing public doesn't really care about flashy-yet-useless technology. They want Web sites that do something for them: provide a service or entertainment; help get a job or a date; check bank account balances, stock prices, interest rates, availability of airline tickets, today's weather ... and so on.
In this article I will look at the doctype in a lot more detail, showing what it does and how it helps you validate your HTML, how to choose a doctype for your document, and the XML declaration, which you’ll rarely need, but will sometimes come across.
Page layout forms the foundation in presenting search results. Your layout decisions for search results pages will have tremendous impact on the user experience for your entire site. Choosing the right width for search results is important, and the optimal width for search results may be a great deal narrower than some people using big monitors would believe.
We need to develop a rhetoric of objects to understand the new way in which we must create and deliver content over the Web. We are facing a new multiplicity of audiences—niche groups, and even individuals, to whom we offer customization and personalization. With our new tools and new ways of thinking about what we create, we are inventing informative objects that address the needs of our audiences, letting go of the concept of a document, as we plunge into a world of small chunks of content. In this presentation, I consider how this new approach to technical communication affects our ideas of audience, invention, arrangement, style, delivery, memory, and character—the canons of traditional rhetoric.
Most information on the World Wide Web is gathered in short reference documents that are intended to be read nonsequentially. This is particularly true of sites whose contents are mostly technical or administrative documents. Long before the Web was invented, technical writers discovered that readers appreciate short 'chunks' of information that can be located and scanned quickly.
Dopo aver esplorato i principali modelli di classificazione elaborati dalla biblioteconomia, l'articolo si sofferma sulla classificazione a faccette (Faceted Classification), illustrandone le possibili applicazioni al web e i gli indubbi vantaggi che ne derivano.
In this paper, we present a novel method for the classification of Web sites. This method exploits both structure and content of Web sites in order to discern their functionality. It allows for distinguishing between eight of the most relevant functional classes of Web sites. We show that a pre-classification of Web sites utilizing structural properties considerably improves a subsequent textual classification with standard techniques. We evaluate this approach on a dataset comprising more than 16,000 Web sites with about 20 million crawled and 100 million known Web pages. Our approach achieves an accuracy of 92% for the coarse-grained classification of these Web sites.
When McAfee Inc. recently introduced its ProtectionPilot software--a dashboard-type management console for its Active VirusScan SMB Edition and Active Virus Defense SMB Edition suites--the trial downloads were fast and furious: In the first 10 weeks after release, more than 20,000 users went online to get a copy.
