Top Most Is Apple IPhone4S Siri going to replace the Google Search Engine

I am sure this is one of those most optimistic title you can think of but that is what my first thought after seeing apple introductory video of Siri, there new voice recognition and task completion service integrated on Apple Iphone4s. I was amazed with smoothness and accuracy of Siri as shown on that video. You just say siri what's whether, find me new restaurant, traffic status and you get a response you are looking for, this looks to me a new way of searching web and technology.  Asking questions is more natural than typing on Google and believe if Siri kicks of like that you will suddenly have more search volume via siri than google, though only limiting factor is not everybody has Apple Iphone4s with them :). People are also thinking Siri as Google Killer let's see.

Top Most How to write Helloworld in Google Dart with Example - Dart Tutorial

Google Dart  Program Example Tutorial

Google dart is now released and its time to try google dart and see how much it offers to a programmer and whether it is suitable language to replace JavaScript or not. As a language my first impression of Google dart is great it looks so much familiar with Java my favorite programming language and this motivate me to write this hello-world example in Google Dart and execute it , run it and see how it works. Google dart has Class and Object, it has final keyword, String Class , Object class , extends keyword and many more I going to learn but it really look structure because it has google dart compiler which shows warning and error like any other structure programming language.

In this Google Dart tutorial we will see How to write Helloworld in Google Dart and How to run Google dart program using Google Dartboard Application which is a browser based application, allow you to write and run Google Dart Programs. This is the easiest and quickest way to get a feel of Google Dart language itself before trying it with HTML code. Google Dart also has compiler and html converter which allow you to convert Dart code into JavaScript and use it. We will see about how to convert Google Dart Code into JavaScript in next article. For now let's start with this step by step guide of writing Google Dart HelloWorld Example and running it.

Step by Step Guide to Write and Run Google Dart Example

I. Open http://www.dartlang.org/ in your browser.

Make sure you use Mozilla Firefox, Google Chrome or Apple Safari. Google Dartboard application won’t work on Microsoft Internet Explorer, though support is coming in may be few days or week.also if you are using Mozilla please use latest version, Google Dartboard was not working on my Mozilla Firefox 3.6 versions. Once you open this link Google Dartboard Application will be open on your browser and first example which it has is "Hello Dart" as shown in below screen.

II. Important points about Google Dart structured programming language

Now you have two options either edit the existing program or write a new program.

Before writing new program let’s see few points about google dart language.

1. Like Java google dart program will start with main () method.

2. You can declare Variable using "var" a JavaScript style or using correct type like String or int using Java Style , for example below two code  are same.

String text = "NYSE is biggest Stock Market in world";

var text = "NYSE is biggest Stock Market in world";

It depends upon your choice whether you want to adopt javascript style or Java Style. Since I am a Java programmer I found Java Style more intuitive and easy to use.

3. You can assign incorrect type to variable e.g. in this example assigning "text" as int, your programe will run but Dart compiler will show warning related to incorrect type.

int text ="google dart compler will show warning but programme will run".

4. Instead of var or a formal type, you can use final keyword and your program will run successfully.

5. Each statement ends with semicolon ";" otherwise compiler will throw error "Unexpected token "IDENTIFIER expected" or "; expected"

6. For displaying value of variable we need to use interpolation or jsp expression language style "${var}" or else it will complain as "cannot resolve text".

7. We can display string as literal, exactly same as in Java. print() method is similar to Perl, java or any other language. For example

print("This is String literal");

III. Our first google dart program

main() {

  String tradingSecrets = "High Frequency Trading requires extremely fast computers";

  int latency = 10;

  String message = "Google Dart language";

 

  print('Hello world in ${message }');

  print("This is String literal just like Java");

  print( '${tradingSecrets}');

}

Output:

Hello world in Google Dart language

This is String literal just like Java

High Frequency Trading requires extremely fast computers

IV. Running your Google Dart program

Just press the Run button as shown in the above image, it will contact darn server and run your program, sometime you may get error as "The darn server failed to respond." but mostly you see out of your google dart program.

This is the first Google Dart tutorial there are more to come but this is good to start and get feeling of Google dart language. Google Dartboard application is easy to use and execute google dart program which reduce learning curve but converting google dart program to JavaScript and than running into HTML file like JavaScript requires little effort which we will see in next article.

Top Most Dennis Ritchie, Creator of C language and Unix has passed away

I just come to know about this sad news that Dennis Ritchie passed away, It is second blow to technology world after Steve jobs who has recently passed away. Dennis Ritchie is the first programming figure I come to know when I started my programming classes in C and C++ and that's why when I heard this news I feel sad about it and suddenly I remember my programming days and I thought about this post to pay my tribute and remember him.

There is lot of Great information available on Dennis Ritchie in web and Wikipedia but two of its main contribution is:

1) C Programming language, which is still number one after Java.

2) His Contribution in UNIX Operating System which is best Server Operating system available.

3) Author of book

• The C Programming Language (1978 with Brian Kernighan; see K&R)
• Unix Programmer's Manual (1971)

Let’s remember this programming genius and pay 2 minute tribute to him, without his C language and immense contribution to programming language, community will never forget him.

May god rest his soul in piece.

Top Most Top 10 Puzzles, Riddles, Logical and Lateral Thinking questions asked in Programming Job Interviews

Puzzles, riddles, logical questions, and lateral thinking questions are integral part of any programming job interviews. I missed to include some puzzles, when I shared my list of top 30 programming interview questionsearlier, and couple of my friends requested to share some puzzles as well. These puzzles and lateral thinking questions are mostly collected from various Java programming interviews on Investment banks, but they are equally useful to any programming job interviews. I have seen more puzzles and logical questions at junior level i.e. 2 to 4 years. These kinds of puzzles, if asked at the beginning of interview, can make or break the interview. It’s not easy to solve them, especially when you see them first time, but what is surely not to do is give up without try, even if you can't think of answer, try to show rational approach. Remember it's OK, if you don't answer any puzzle question, but your approach towards unknown problem get noticed. At the same time lateral thinking questions offers several answers, and you can give your own explanation as well, but make sure it must look genuine and seems logical. Puzzles and riddles also forms a big chunk of Microsoft and Google Interview questions as well, and they are some really nasty and tough to answer. Anyway, I have not provided answers of these puzzles and logical questions, so that you can at least give it a try. Immediate answers kill the purpose of puzzles and riddles, and it's fun to solve them by yourself. By the way, you can easily find answers of these puzzles using Google, as they have asked numerous times on various programming interviews on software and technology companies.

Top Most Google Dart: New Programming language to replace JavaScript

Google Dart: Structured Web Programming language

Google has launched its much awaited mysterious DART web programming language. Ahh another programming language…, why does google launched a new language Google DART? What I read from web is that google is trying to replace JavaScript as main web scripting language. Over the years from Netscape Era JavaScript has evolved, formed a large based of Developers and has existing codes, framework and utilities, so I am not sure how far Google DART can go but this is a serious attempt to replace JavaScript much in the line of Chrome which was launched to replace Internet Explorer and What we see now is they are living happily with there own market share though Chrome is growing and snatching market share form other browsers.

Now let’s get back to Google Dart, according to leaked Memo, Google perceives that Security Problems of JavaScript cannot be solved by modifying or evolving language and it has tried to solve that on Google Dart: A structured web programming language on its own way.

Example of Google Dart Code
Let's see an example Hello World program in Google Dart, I bet you will see and understand it in one second if you written code in Java or C#.

  main(){
  print("Hello World from Google Dart");
  print("My Name is Google Dart and I am going to replace JavaScript");
  }

Nothing fancy simple and familiar syntax and that's what Google reiterate as one of design goal.
You can execute Dart Code in two ways either in native Dart Virtual Machine; Google is planning Dart support in Chrome and push other vendors to do the same.

Salient feature of Google Dart

Familiar Syntax: if you look Google Dart code you will easily able to understand what's going on because its syntax is quite similar to Java,Which is undoubted world famous programming language.Its is also similar to C# on same line.

High Performance: Dart is promising high performance from web browser to hand held devices to Server Side Execution.

Runs in Virtual Machine: Similar to Java Google Dart also run on Virtual Machine.
Google Dart is semi typed language where you can switch from typed to untype based on your need.

Open Source: Google Dart is open source project and it comes with set of tools for compiling and executing Dart Code. You can check dartlang.org for further details.
 

How Google Dart will get Popular

Google is doing its hard work to get Dart accepted by web developers and community and arranging support, tools and execution environment for Google Dart.

1. Google will provide support of Dart in Google Chrome by integrating native virtual Machine and it will encourage to Microsoft and Mozilla to do the same.

2. Google will provide a Cross Compiler which will convert Dart to ECMAScript 3 , so that it can run on Non Dart Browser. This will be the major step as getting Dart Virtual Machine integrated on all popular brower might take some time.
 
 
What is positive for Google Dart

Though Google Dart is a new programming language and anything new takes it time to get adopted and supported by community and that's the most difficult phase for language. Google Dart is not an exception but there are some positive facts which suggest that it can go a long way:

Technologically advanced: Dart is technological advanced than JavaScript and since it aims to fix security and other problems of JavaScript it will definitely have an appeal.

Google: Since language is developed and launched by Google, expect future support, marketing and strong backup from Google.

Familiar Syntax: Google Dart doesn't reinvent the wheel at least on language syntax it's quite familiar to Java and C# which gives it easy access of large community of Java and C# web developer.

Google Dart Cross Compiler: Cross compiler will make Dart running on browsers which doesn't have native Google Dart Virtual Machine, if google gets it right this would be the biggest point and can provide language an initial thrust.

High Performance: Google Dart Promises high performance from web browser, web Server to hand held devices
