BETA is a pure object oriented programming language developed by Scandinavian School in System Development, Nordic Universities.

This was released after a series of enhancements of their first object oriented language SimulaI which was a simulation language. Soon it was generalized into Simula67 which had the object oriented framework, and worked on the concepts of class, sub-class, virtual functions etc. This was enhanced by another object oriented language Delta that worked for system description; this meant it could express predicate logic and state changes. This was a non-executable effort and thus did not qualify as a language. So it was decided to design a programming language Gamma that works as Delta but is executable.

Eventually, Gamma was never made, rather Beta was made. While Beta was being made, it was realized that Beta was much more powerful than what Gamma would be or ever could be. Beta is a programming language like C++.

Currently, BETA is available on UNIX workstations, on PowerPC Macintosh and on Intel-based PCs. BETA has an optimum balance between compile time checking and run time checking. The type cast checking is done at compile time, however, for the entire set of type check and type conversion to be done at compile time requires a lot of time and thus increases the complexity of a program. Thus, an optimum balance has been made.

BETA is a logical description of the language. It works on the concepts of class, sub-class, virtual functions etc. It also contains transient variables, ones whose scope is program execution, and persistent variables, those whose values are retained in the disk space and are available at the time of next execution.

You put up a website to attract clients for your professional service business. Maybe you even put up a sales letter - a solo web page designed to promote an information product, tangible product, or seminar.

And so far...nothing! No takers. No sign-ups for your ezine. What's going on?

(1) Get solid evidence that people want your product -- and will buy it online.

Even on eBay and craigslist, some products go unsold. Some markets don't buy online, download ebooks or listen to mp3 files: they shop in brick and mortar stores, buy books at Borders and listen to CDs.

(2) Make sure you have targeted traffic coming to your site.

If you have no traffic...well, there's your answer. But not all traffic is equally valuable. Your keywords, positioning or referral site may be attracting visitors who are outside your target market.

(3) Encourage each visitor to begin building a relationship with you.

Often visitors won't buy on a first visit. So you need to invite them to sign up for an ezine, an ecourse, or even a downloadable manual. Some people read my ezine for over a year before they buy from me.

(4) Showcase unique, meaningful benefits for your target market.

Many professionals focus on how they deliver the service instead of how clients feel about their new lives. And you need to tell readers why you're unique - why nobody else can make the same offer.

(5) Make it easy for your visitors to say yes.

Believe it or not, when visiting other people's sites, I often have to hunt around for an order form when I'm eager, even desperate, to get my hands on a product. Ask visitors to buy...and consider adding some bright red arrows to point them in the right direction.

(6) Create a sense of urgency.

Ideally, your product or service reaches readers by connecting to their pain and their toughest challenges. But you also need to suggest reasons for buying today - not next week, not later.

(7) Test...and test some more. For example:

Test 2 or 3 versions of your headline. Sometimes a news-oriented headline actually works better than a sales-oriented headline or vice versa.

Test backgrounds. I once tripled sign-ups to my ezine by changing the background color.

Test the small stuff. Once I compared two google adwords ads. I changed the spelling of one word in the headline - from midlife to mid-life. The hyphenated version attracted 40% more clickthroughs. Go figure.

Bottom Line: Even when experts create your marketing message, you need to keep evaluating the effectiveness of your marketing materials, especially your website. The Internet gurus share one passion: testing and revising. They're constantly enhancing their sites and their messages. And the rest of us need to do the same.

Here are the simple ABC's of web development.

A. Graphics

Graphics is very essential in web development because this is what visitors gauze your site if it is worthy of their time.

So what really makes a graphic to be effective?

First, the graphic should be small. Consider using images that are 10 to 12 KB per image because if you will use larger images, it will slow down your site.

Visitors to your site will likely to leave if your site takes too long to display so it is better that you use images that are attractive and easy to load.

Second, when it comes to graphics, you have to use images that have direct relation to your site. You would not display an image of Hollywood artist to promote the product you are selling, as this will cause confusion to your visitors.

Lastly, blinking graphics are not ideal in web development because blinking objects are really annoying and distract readers. More often readers leave web sites with excessive flash or blinking objects most especially when these objects hinder them from reading the whole web page.

B. Advertising

Advertising is lifeline of web sites and you have to handle them effectively to ensure success of your site.

When in comes to advertising, you have to remember two things, the number of ads and how related it is to your site.

The number of ads should be just enough to give room to other contents of your site. If they are overlapping contents of your site, then maybe that is why your site lags behind in web searches.

Next, you should only post ads that related to products or services offered. If they are related, your readers will likely to open the links to your ads but if they are not related the ads might not be opened.

In the end ads generate income but if they are driving your visitors away, then maybe its time to remove some of your ads and just stick the ones that are related to the content of your site.

C. Web Content

Content is also another essential factor in success of your site. It will be better if you have articles that your visitors can read on a daily or almost weekly basis.

Informative content will likely to increase your visitors as they will bookmark your site and then send your links to other friends and family members to invite them to visit your site as well. But for others to recommend your site, you really have to offer not just ads or graphics but rich and informative content.

For example, you are selling a product, it will be better if the site not just offer the products but also give tips on "how to-" like how to choose, how to use and where to buy.

Meanwhile, if you are maintaining a web blog, make sure that the site is readable and the topics being discussed are really interesting.
