10 Useful Web Application Interface Techniques

More and more applications these days are migrating to the Web. Without platform constraints or installation requirements, the software-as-a-service model looks very attractive. Web application interface design is, at its core, Web design; however, its focus is mainly on function. To compete with desktop applications, Web apps must offer simple, intuitive and responsive user interfaces that let their users get things done with less effort and time.

In the past we didn’t cover web applications the way we should and now it’s time to take a closer look at some useful techniques and design solutions that make web-applications more user-friendly and more beautiful. This article presents the first part of our extensive research on design patterns and useful design solutions in modern web applications. Below you’ll find a collection of 10 useful interface design techniques and best practices used in many successful web-applications.

1. Interface elements on demand

2. Specialized controls

3. Disable pressed buttons

4. Shadows around modal windows

5. Empty states that tell you what to do

6. Pressed button states

7. Link to the sign-up page from the log-in page

8. Context-sensitive navigation

9. More emphasis on key functions

Anti Spyware or Spyware??

Spyware has become the most prominent computer security problem. How do you choose a good spyware removal tool? Beware of antispyware software which installs spyware/adware to your computer. Spyware is a hidden software program. It is often used to monitor the browsing and shopping habits of computer users. Spyware can also be a remote control program that steals confidential banking and personal information. Spyware has quickly become the most prominent internet security problem. According to the National Cyber Security Alliance, spyware infects more than 90% of home PCs. Recent survey shows that spyware is also sneaking into the network of corporate computers.
Spyware is often coupled with free downloads, such as free music, game and software downloads. Spyware may slow down computer, hijack homepage and create uncontrolled pop-up advertisements. Some spyware programs can remain unnoticed, secretly gathering information from the computer. Once installed, spyware is difficult to remove without the help of dedicated antispyware software. Due to the rise of spyware activity, antispyware programs are in great demand these days. But are these spyware removal tools the same? Do they provide the security consumers need? There are many reports that some antispyware programs installed their own spyware and adware to the computer. One consumer was quoted saying: “It’s a rip-off. I downloaded the free trial of an antispyware program, only to find out that it added its own adware to my computer.” Other consumers have complained that the antispyware program they use cannot detect all spyware programs.
Some even slow down the computer and create pop-up advertisements. There are a few good antispyware programs in the market today. On the other hand, dozens of spyware removal programs are blacklisted by consumers. Beware of spyware removal tools that are heavily promoted by e-mail campaigns. Never run any free downloads and free scans from unknown software publishers. Their programs may as well be spyware programs themselves. Read independent product reviews from renowned computer magazines or reputable sources. Spending some extra time in research can save you a lot of hassles in the long run.

Good Computer Maintenance

Normally we think of maintenance as a chore, something we have to do to keep things running smoothly and prevent problems down the road, whether with our car, house, or computer. But with a PC, maintenance can actually be fun ... approached from the right perspective. Automatic Updates The "joy" of computer maintenacne takes many forms.

These days, automation is the byword. Operating systems such as Microsoft Windows and Symantec's Norton Interenet Security let you automatically keep crucial parts of your computer system up to date. It's fun to watch the technology keep tabs on itself. The security vulnerablilites of Windows are legion, and this forces you to download patches and updates if you want to minimuze your exposure to hackers seeking to break into your system over the Internet. You can run Windows Update periodically through Microsoft Internet Explorer, which automatically detects which versions of Windows components you currently have installed and, by checking with Microsoft's site, which have newer versions. Or, if you are running Windows XP Home Edition, you can automate things even further by directing Windows to check for "critical updates" by itself at the frequency and time of your choosing. From the Control Panel, go to System and click Automatic Updates to specify your settings. Website Updates You can keep your other software up to date by periodically checking the Websites of the respective manufacturers. Typically, by pulling down the program's Help menu, you will quickly be directed to the site. But the Website VersionTracker (www.techtracker.com/products) does something similar with multiple programs, for free, whether you have a Windows PC or a Mac. The ad-supported site has 30,000 programs in its database. Pay versions, starting at $24.95, automatically alert you when new updates of programs that you're using become available. Using Utilities Staying up to date is crucially important these days in keeping the bad guys away from your computer and those using it.

A good utility suite for this is Norton Internet Security (www.symantec.com), which combines such crucial tools as a firewall, anti-virus program, porn-blocker, spam filter, spyware detector, and pop-up ad blocker. If you use the program, make sure you let its LiveUpdate feature automatically keep your virus definitions and other components up to date. Symantec's other utility suite, Norton SystemWorks, is less useful, and if you need system tools more powerful than those provided by Windows itself, a better package overall is V Communications' SystemSuite (www.v-com.com). SystemSuite includes tools for preventing and recovering from hard disk crashes, recovering accidentally erased files, completely uninstalling programs you no longer need, and completely shredding sesitive files. It also has an excellent file manager, PowerDesk, that makes quicker work of copying, moving, deleting, and otherwise manipulating files than Windows Explorer. With today's large and fast hard drives and more efficient operating systems, one maintenance task that's no longer as necessary is disk defragmenting. When working with files over time, they invariably wind up stored in places at different locations on your hard disk. Running a defragmenter gathers up the pieces and places them together in one contiguous location.

Recent testing by the computer magazine PC World, however, showed that defragging no longer improves performance the way it used to. It still makes sense to defrag once in a while, though unless it's for a network file server, there's usually no need to buy a separate program for this beyond what comes with Windows itself. So in all ... even automated maintenance can be fun in that it is automated and can leave you more time for other endevours.
