Debate Against Net Neutrality

Debate against net neutrality

Net Neutrality

An intractable technology battle -Net Neutrality, It flooded the news, It has been in the law of court and sooner or later it is going to affect you .

I would like to stample a conception, that is flow of concept, contravention, it's application and it's inception that is when it was planned are the three major aspects of transcendence of net neutrality in the hovered minds of lots of innocents 

A very cheerful morning to one an all present here. RESPECTED jury members, fruitful teachers, worthy opponents and my dear friends. Today I'm going to have contention against net neutrality.

My worthy opponents represented this debate as sentimental than being fundamental, but businesses are not let on sentimental thoughts only.

The given topic cardiolates the interest of two parties, one is ISP I.e internet service providers and other is the consumer like you and me and to fully understand we need to think as a part of parties in an unbiased way.

Some points were put on like airtel zero and special packs of WhatsApp.

My intelligent audience, I would like to clear your mind about this that there is nothing wrong in it.

Now just think like a shopkeeper who lowers the prices of goods in shop temporary to introventialy attract more customers. Then whats wrong in this?

In place of shopkeeper we have flipkart who collaborated with airtel to increase their business and acquire new customers.

Coming to WhatsApp, flabbergastly,

in our daily life we prioritise everything,which is important to us and which is not.

Assume that you have two messaging app in your smartphone, say one is WhatsApp and other is Wechat, and on an average you receive 100 texts on WhatsApp whereas only 20 on Wechat, then it is clear that WhatsApp is giving better service than Wechat, WhatsApp has more importance and priority than Wechat in your life , then why will you pay same amount for two different level of services?

Some people might say that big companies like Facebook supports net neutrality . I will say that this is only because they want to keep aloof the FB title "It is free and always will be"

They are scared that if net neutrality is dismissed they they might have to change it to "It was once free and never will be"

I just want to say that just like a normal shopkeeper, internet service providers should also have right to manage their network so that an adequate level of service is provided to customers.

Some people might say that internet was built to share information for free in an indiscriminative way 

but nothing is paraniel in this world, and thus time is over for net neutrality .

Now assume that a city has two doctors , one with better services and equipments, then of course people of that city will make their choice according choice, according to level of service they want.

Then why not in the terms of internet?

Today videos of Netflix and YouTube clog our pipes with huge amount of data consumption.

Or take example of BitTorrent client which use our lines to download insane terabytes to illegally download movies, games and many more similar things.

services like Skype and Viber provide free calling reducing the excellence of telecommunication companies.

Does need not to pay?

what I think is that charging everyone same even if they provide different level of services isn't fair.It is not a justice.

one net neutrality is dismissed, ISPs will net better control over network

proper bandwidth distribution will be there

Illegal acTivities like BitTorrent client will be banned

website like which contain pornographic content will be blocked

underage students won't be wasting their time on social networking sites

I hope that there are many more such examples but the time limit has bonded my words 

At last I would like to say that either my opponents has chosen wrong side or they are moron.

but my intelligent audience, the ball is still in your court, think once again before it's too late 

Let's oppose net neutrality and be a part of rising economy.

Visual Basic Programming for Beginners: Declaring Variables and Assigning values (03)

Before proceeding, do read Visual Basic Programming for Beginners: Getting Started (02)
 Visual Basic Programming for Beginners: Declaring Variables and Assigning values (03)
In the previous post we have learned how to get started with VB in Visual Studio and we also created a "Hello World" Program. Hope that you are now familiar with Visual Studio environment and the Structure of a VB program.

So now its time to proceed forward in our journey of learning VB

Now we will learn how to declare variables and assign values to them.

Take a look at following code
x=7
y=x+3
Console.WriteLine(y)

Above code assigns "x" value "7" and "y" value "x+3", so its pretty easy to understand that Console.WriteLine(y) will display value "10"

Here "x" and "y" are variables which can be defined as A bucket in computer memory in which you can put values, overwrite existing values and also retrieve values.

Variables can be made to create different type of values like integer,character, string, decimal no.s and many more.

Declaring Variables(syntax):
Integer Type variable
Dim x As Integer
Dim y As Integer
"Dim" keyword is used to declare a variable i.e to provide dimensions to the variable in the computer memory
So now let's implement this in Visual Basic.

• Program To add integer values

Module Module1
  Sub Main()
          Dim x As Integer
          Dim y As Integer
          x=7
          y=x+3
          Console.WriteLine(y)
          Console.ReadLine()
  End Sub
End Module

Note: To make your program more understandable, make comments in your program
How to make comments in VB?
We can make comments in VB by the use of Single quote('), and VB supports only single line comments
It goes like this:
'This is a comment
'Compiler won't detect it
'Only single line comments are possible
'Every character after single quote counts in comment 

String Type variable
Dim myname As String
myname = "MAK"
alternate way
Dim myname As String = "MAK"
or
Dim myname = "MAK"

• Program to print String On console

Module Module1
  Sub Main()
          Dim myname As String
          myname = "MAK"
          Console.WriteLine(myname)
          Console.ReadLine()
  End Sub
End Module

Generic Type variable
Generic datatype variables are those who can store data of any datatype
It goes like this
Dim x
And that's all, you have created a generic type variable "x" which can store any type of data

• String Concatenation in Visual Basic

"&" act as a string concatenation operator in VB and program to use this is as follows
  

• Program to concatenate two datatype as string

Module Module1
  Sub Main()
          Dim x As Integer = 7
          Dim myname As String = "MAK"
          Dim myfirstTry As String = x & myname
          Console.WriteLine(myfirstTry)
          Console.ReadLine()
  End Sub
End Module

Compile this code and check out the output, it is interesting.

Type Casting:

• Integer To string

           Dim x As Integer = 7
           Dim myname As String = x.ToString()
             or
          Dim myname As String = CStr(x)
   
So stay tuned and keep coding and practicing till next post.   

Visual Basic Programming for Beginners: Getting Started (02)

Before proceeding, do read Visual Basic Programming for Beginners: Introduction (01)

Well, in the previous blog we have gone through how to get things ready to learn Visual Basic and why we should learn VB and its importance in today's world.

Now we will start working on visual studio and will try to get familiar with it's interface and will build our first VB program.

Step 1:
Open visual studio 2013 on your desktop
Step 2:
Click on File ->New ->Project
Step 3:
Under Templates, Select Visual Basic and then Console Application
Step 4:
Name your project and click "Ok"

Will now have a window like this:

Now in the code editor window, you will have default code like this:

Module Module1

Sub Main()


End Sub

End Module

The above is your default VB code which must be there to start with.
where
Module Module1 is your main container of code and
Sub Main() is a sub procedure

Remember that in VB

• Single line of code means single statement unlike C,C++,C# etc where you end with a semicolon(;) 
• Each module or a procedure is end with END Keyword as you can see in above code. 

Now, Hello World Program in VB

Our purpose is just to Print A line of string On Console String on Console Window.

Module Module1

Sub Main()

Console.WriteLine("Hello World")

Console.ReadLine()

End Sub

End Module

In the Above Example Console is a class in WriteLine() and ReadLine() are member functions of this class used to write and read from consloe input.

This was pretty good.

Now Press "START" button to start running your application.

Your output Will be Like this:

 In the above code, the work of  Console.WriteLine("Hello World") was to print "Hello World" On console screen and the work of Console.Readline()Is same as that that of getch() in C that is to hold the output screen until a character is enterd.

So,today we have made our first VB program and learned a basic about it.

Till next post get yourself familiar with Visual Studio Environment and Do goggle about

• Solution Explorer
• Open new project in visual studio
• Open Existing Project in Visual Studio
• Properties bar
• Error List in Visual Studio

Till then keep practicing and coding in Visual Basic 

Visual Basic Programming for Beginners: Introduction (01)

Welcome back readers....
From now on wards, your very appreciated blog "Let's Innovate" i.e http://makcs.blogspot.com will focus on Introduction to Visual Basic Programming.
Mean while you might also find other articles also but don't worry, the VB course will go on uninterrupted side-by-side.

For this series of module I'm going to use following things which you also need to have installed on your PC:

• Windows 7 seven service pack 1(or above)
• Visual Studio 2013
• Interest to learn Visual Basic

If you have any problem with process listed above(regarding downloading, installing etc), please write to me on mywork78601@gmail.com

Why should I learn Visual Basic:

• One of the commonly used programming language in today's scenario
• Best and easy substitute of C#(C sharp)
• Easy To Learn
• No use of semicolons and curly braces(which makes programming complex)
• Very Close to English language
• Can be used standalone, with asp.net, to create console applications, web applications and many more
  

So I think above reasons a good enough to start with Visual Basic Programming.

Thing to be kept in mind:

• Keep the IDE ready with you i.e Visual Studio
• Best way to learn programming language is to practice by your own
• Always type the code by your hands, don't just copy-paste
• I'm just showing you the path, you have to walk on it
• Don't keep quires, just comment them or mail it to me.

So, We will be meeting very soon to begin, till then get things ready.

You can download Visual studio 2013 free from here:
