Recently I’ve had a client who has had problems with the Russian search engine Yandex crawling their website and taking up server resources and bandwidth. Yandex.ru is a popular search engine in Russia unfortuently for many Yandex ignores the Robot.txt file therefore using the “official” method is not an option.
When I first saw this late last year, I’ve thought about these images often since. I’m not a plane spotter but looking at how Kulula has branded their planes, you’ll understand. I’m a fan of Virgin and much of their marketing is free, Virgin jumps on board quickly for anything publicity particularly if it’s free as seen here.

Hello Guys
I’ve started writing Visual Basic tutorials over the past few days and I still have loads to upload and update. I’m trying to keep the tutorials consistent with the style and look. I’m now looking to write other tutorials after I’ve finished educating you of the basic programming syntax Visual Basic.
In the last tutorial we learn’t Visual Basic: String Padding – Aligning Text now lets try something a little bit more practical and learn something on your own merit.
Exercise – Circle Area Calculator
A user requires a program that calculates the area of a circle given the circle’s radius.
Before starting to program identify the inputs, processes (i.e. the calculations and formulas and the outputs of the program.)
This Visual Basic tutorial continues on closely to the to the last tutorial Visual Basic String Addition – Piecing Text Together.
Next we would like to align the results. We would like the output to look as shown below:
In the last Visual Basic: String, Integer and Double tutorial, we were looking at developing a calculator to better understand variables and data types. However the calculator looks very messy, so let’s just clean the calculator up and learn a little bit more.
In the last tutorial we looked at Visual Basic Data Types.
Variables must have a data type. The data type tells the computer how much storage space to provide. It also tells the computer the operations available.
| Data Type | Values | Operations |
| String | Any text, names, addresses, phone numbers | +, <,>,=,<> |
| Integer | Whole Numbers, i.e. 0, 1, 2, -4. Use this when you want to perform math operations. |
|
| Double | Decimal numbers ie; 10.3. Use Double when you want to perform math operations. |
In the last tutorial, we learn’t Visual Basic Input Operators and Variables.
Let’s create a simple program that allows the user to enter two numbers and that displays the total sum of both numbers.

Continuing on from the Hello World program let us personalise the program by asking the name of the user who is using the console.
