Two step verification process Apps For Google: Provide extra layer of security to your Google Account

2011-03-09T01:06:00.004+05:30

Google Apps tools by adding a new two-step verification process. Google announced the new sign-in feature at its Google Atmosphere conference in Paris.

"Cloud computing is about making your information easily accessible from anywhere, on any device," Eran Feigenbaum, director of security for Google Apps, said in blog post. "Until today, organizations looking to secure their information beyond a password have faced costs and complexities that prevented many of them from using stronger security technologies. Today, we are changing that with the introduction of a more secure sign-in capability for Google Apps accounts that significantly increases the security of the cloud: Two step verification."

2-step verification adds an extra layer of security to your Google Account by requiring you to have access to your phone – as well as your username and password – when you sign in. This means that if someone steals or guesses your password, the potential hijacker still can't sign in to your account because they don't have your phone.

Getting started with 2-step verification

2-step verification helps protect a user's account from unauthorized access should someone manage to obtain their password. Even if a password is cracked, guessed, or otherwise stolen, an attacker can't sign in without access to the user's verification codes, which only the user can obtain via their own mobile phone.

Two-step verification is easy to set up, manage and use. When enabled by an administrator, it requires two means of identification to sign in to a Google Apps account, something you know: a password, and something you have: a mobile phone. It doesn’t require any special tokens or devices. After entering your password, a verification code is sent to your mobile phone via SMS, voice calls, or generated on an application you can install on your Android, BlackBerry or iPhone device. This makes it much more likely that you’re the only one accessing your data: even if someone has stolen your password, they'll need more than that to access your account. You can also indicate when you're using a computer you trust and don't want to be asked for a verification code from that machine in the future.

AJAX - Change the Shape of World

2010-10-23T14:55:00.001+05:30

Would you like to learn AJAX By your own?

If yes, Join with Me(Tushar). And follow the steps given below:

1. Download prototype.js file from this website http://prototypejs.org/download

Prototype is JavaScript framework,

Prototype is freely distributable under the terms of an MIT-style license.

For details, see the Prototype web site: http://www.prototypejs.org

2. Create a new folder and store prototype.js in this folder after creating your first jsp file.

3. Save as ajax3.jsp.

• Write content on file ajax3.jsp as under.

Then Create second jsp file and save as hello1.jsp.

Write content on file hello1.jsp as under.

Then you start apache-tomcat and run our first jsp file whose name is ajax3.jsp.
The output as under

Then in text area you write Your Name (e.g: Tushar).Click to submit button.

· In this application, we use inbuilt function which provides AJAX environment.

· In ajax3.jsp file, we use function() or function(xhr). In this application, I have put a simple two textbox and one Button.

· When we write any name in textbox like Tushar, that time hello1.jsp perform its real role to fetch the name which we write in textbox and AJAX application replace name on the place stranger.

Benefit of this application: when we click on submit, a page is not reloaded, but only name will be replaced.

If You want More knowledge about AJAX, See my own presentation shown in below

What Is JAVA? Why I Choose JAVA, behind this question some reason , That's reason i share with you all guys.

2010-04-29T02:19:00.006+05:30

Java is a programming language and environment invented by James Gosling(James Gosling Blog’s Link on sun/Oracle) and others in 1994. Java was originally named Oak and was developed as a part of the Green project at the Sun Company.
James Gosling Key Note at Tech Days 2010, Hyderabad.

The writing of Java began in December of 1990. Patrick Naughton, Mike Sheridan, and James Gosling and were trying to figure out the "next wave" in computing.

Here some of best feature of java,

why java is platform independent
Jvm Java platform indipandent.
When Java Code is compiled a byte code is generated which is independent of the system. This byte code is fed to the JVM (Java Virtual Machine) which resides in the system. Since every system has its own JVM, it doesn't matter where you compile the source code. The byte code generated by the compiler can be interpreted by any JVM of any machine. Hence it is called Platform independent Language.
Java's bytecodes are desgined to be read and interpreted in exactly same manner on any computer hardware or operating system that supports Java Runtime Environment.

why java is secure
Java Security
The Java Secure Socket Extension (JSSE), which is a set of Java packages that enable secure Internet communications, is a framework and 100% Pure Java implementation of the Secure Socket Layer (SSL). These packages enable you ,the Java developer, to develop secure network applications that feature the secure passage of data between a client and a server running any application protocol, such as HTTP, FTP, Telnet, or NTTP, over TCP/IP.
For more information on java security refer this link.

why java is robust
Refer this Java Docs Link.

And finally A Big Question Why I choose JAVA?
When i ask this question to myself(Why I choose JAVA?)then i find 1 more question,
why java is better than .net

I am building a list, that's actually I listed with help of my own work on java, and other experiment on java with compare of other programming language.
Anyway, I have now accumulated Some reasons. Hopefully, with feedback and suggestions from the Osum community and you guys also tell me more about on this question. the goal of more reasons will be achieved with help of you guys also.

Some more and important reasons,

Here now are reasons 1 to 5:

1. Run on Multiple Platforms from the Smallest Devices to the Largest Mainframes.
Run on multiple platforms, from smart cards, embedded devices(JStamp), cell phones(Nokia, Motorola, Ericsson etc), pdas (Palm, Symbian, Sharp),laptops and desktops (MacOS, Linux), servers (Unix based), Non Stop Servers (Tandem) to Mainframes ( IBM ).

2. Run Dynamic Languages
Run Dynamic Languages like Python (JPython) , Scheme (JScheme, SISC, Kawa), Ruby(JRuby), Smalltalk(Bistro). In comparison a commercial development effort to port Python to .NET showed dismal performance. Furthermore, a paper comparing the CLR and the JVM came to similar.

3. Compile in One Platform Run in Another.
Visual Studio.NET and .NET SDK End User License Agreements specifically states that code compiled with it cannot run in non-microsoft platforms.

4. Smaller Runtime Download
The Java Runtime Evironment (JRE) is a 8MB runtime download, .NET runtime download is over twice as large (i.e. 20 MB).

5. No mandatory upgrades. No subscription fees. No software insurance fees.
How many MIS organizations are held hostage to microsoft's draconian licensing policies?

6.and last a major reason to use java and put my future in java, because java is open source.
I think this is a major difference between java and .Net.

7.For moreinformaion about this question Is Java better than .net or not see this two link and after you decide java is better than .Net or not Link 1 link 2

Here some other reason to proof Java is Better then .Net. With Help of internet and other resources.
1. Run on Multiple Platforms from the Smallest Devices to the Largest Mainframes.
2. Run Dynamic Languages
3. Compile in One Platform Run in Another.
4. Smaller Runtime Download
5. No mandatory upgrades. No subscription fees. No software insurance fees.
6. Run Multiple Versions of the VM (Runtime) on the Same Machine
7. Large Innovative Open Source Community
8. Low cost Commercial Quality IDE’s
9. More Available Jobs
10. Better and Standardized Connectivity to Legacy Applications
11. Multiple Vendor Choice and Support
12. Compile to Machine Code
13. Future Proof
14. Most Popular Language in the Corporation
15. Larger Talent Pool
16. More Contributions From R&D Organizations
17. Government Approved
18. More Homogeneous and Less Complex Environment
19. More Deployment Options
20. More Searchable References
21. Better support for Software Process Best Practices
22. Mature Object Oriented Relational Mapping Tools
23. More Productive Coding Tools
24. Cross Platform Integration with Other Languages
25. Higher Paying Jobs

Finlay you have other best feature to use JAVA tell me, i always waiting to those reason who make java is better than .Net.

How can I become a sun certified Java programmer????????

2010-01-14T11:46:00.002+05:30

This foundation certification is for programmers interested in demonstrating proficiency in the fundamentals of the Java programming language.

To prepare for this certification, you can take the following recommended course bundle via the SAI Program:

Fundamentals of the Java Programming Language is intended for students with little or no programming experience. The course teaches the significance of object-oriented programming, the keywords and constructs of the Java programming language, and the steps required to create simple Java technology programs. Students taking this course can receive a solid basis in the Java programming language upon which to base continued work and training. The course features the Java Platform, Standard Edition 6 (Java SE 6) platform, and uses the Java SE Development Kit 6 (JDK 6) product.

The three (3) courses under Fundamentals of the Java Programming Language are:
WJ-1101-SE6 – Introduction to the Java Programming Language
WJ-1102-SE6 – Implementing Basic Constructs in the Java Programming Language
WJ-1103-SE6 – Implementing Object-Oriented Concepts in the Java Programming Language.

You might remember that Fundamentals of the Java Programming Language course are the same foundation courses for the Sun Certification Java Associate (SCJA).
The SCJA IS NOT A PRE-REQUISITE FOR SCJP.

Once you've completed these three (3) initial courses, you'll be ready to move on to the next step which is the course called the Java Programming Language.

The Java Programming Language course provides students with information about the syntax of the Java programming language; object-oriented programming with the Java programming language; creating graphical user interfaces (GUIs), exceptions, file input/output (I/O), and threads; and networking. Programmers familiar with object-oriented concepts can learn how to develop Java technology applications. The course features the Java Platform, Standard Edition 6 (Java SE 6) platform, and utilizes the Java SE Development Kit 6 (JDK 6) product. The students perform the course lab exercises using the NetBeans Integrated Development Environment (IDE).

The five (5) courses under Java Programming Language are:
WJ-2751-SE6 Java Programming Language: Getting Started
WJ-2752-SE6 Java Programming Language: Understanding the Building Blocks
WJ-2753-SE6 Java Programming Language: Applying Exceptions, Collections Framework and Input/Output Classes
WJ-2754-SE6 Java Programming Language: Designing Graphical User Interfaces
WJ-2755-SE6 Java Programming Language: Applying Threading and Networking Concepts

Once you have completed all eight (8) courses, you're one step closer to becoming a Sun Certified Java Programmer.

I also recommend taking the ePractice exam for the Sun Certified Programmer for the Java Platform, Standard Edition 6 (WGS-PREX-J065C) before you take your official exam at a Prometric Testing Center.

Good Luck!
