Software is taking over the world, actually it already did. We can see today that more and more system’s are going online and the need for developers and coders is ever increasing. As a consequence of software usage increase in every industry the need for developers, managers, system administrators, business analysts, quality assurance managers and cloud infrastructure specialists is ever increasing. The demand for development is increasing exponentially like a weed. As a matter of fact world has run out of developers.

USA has run out of developers almost fifteen years back, USA is able to sustain because most of the IT development has been outsourced, in-sourced, extra-sourced and managed in different styles. But even after all this the demand of developers is still at it’s peak and we are not still finding qualified developers.

We can see today that most of the new investments are going into the application development tools and technologies. Investing in current IT developers of a company and training those developers for new technologies is not being undertaken. Companies must step up and increase the training activity for employees and keep them up to the latest technologies.

Demand for IT Developers and IT Training

IT Training is the solution

Companies must ramp up IT training for current employees and must also hire employees and train them on required technologies. In the current market companies are trying to find experienced candidates with existing knowledge and use them on their projects, this policy is already backfiring as newer technologies are getting created every day. As new technologies emerge companies must rethink their strategy and train their employees on the required technologies.
Online training has become the most important mode of training in the last few years. This has given a number of advantages to the trained as well as the trainers.

Corporations are using software to manage internal systems, external client interfacing systems. Each system is required to be available for different devices like desktops, televisions, mobile devices like iPhone & android phones, tablet devices. Each interface requires knowledge of a different technology and skill.

Mobile revolution is introducing billions of users to the internet and these users are your customers. You need to be available on every device and at their fingertips. More developers are required to achieve this.

Companies are having petabytes of data regarding their business and client activity. Companies are trying to analyze the data, find new meanings and create new business models to compete. This field will require hundreds of developers with a wide array of skills.

Html5 and JavaScript are making the web come to life with new apps, games, and interactive systems. We need more developers.

Traditional relational databases are no longer working for companies, they are trying cloud and NoSQL databases. We need more developers.

Windows8, the brand new OS from Microsoft is adding tremendous opportunity for companies to migrate corporate desktop apps to the windows8 format. We need more developers.

Apache tomcat team recently added websocket support to tomcat.
WebSocket is a web technology providing for bi-directional communications channels over a TCP connection.

WebSocket is designed to be implemented in web browsers and web servers, but it can be used by any client or server application. The WebSocket protocol makes possible more interaction between a browser and a web site, facilitating live content and the creation of real-time games. This is made possible by providing a standardized way for the server to send content to the browser without being solicited by the client, and allowing for messages to be passed back and forth while keeping the connection open. In this way a two-way (bi-direction) ongoing conversation can take place between a browser and the server. A similar effect has been done in non-standardized ways using stop-gap technologies such as Comet.

In addition, the communications are done over the regular TCP port number 80, which is of benefit for those environments which block non-standard Internet connections using a firewall. WebSocket protocol is currently supported in several browsers including Safari, Firefox and Google Chrome. WebSocket also requires web applications on the server to be able to support it.

Vulab will provide code with example shortly.

Recently I was helping a colleague to write an article for html5rocks. We used tips from Kevin at google to write the article. Use the tips for your own blog or article.

These are the same industrial-strength tips used by 9 out of 10 technical writers. (That one writer who doesn’t follow the rules explains some of the bad docs out there.)

Literary writing and tech writing have their own sets of conventions. Other writing forms are like strolling on meandering paths in a meadow where you’re supposed to take in the words and enjoy them; technical writing is like driving a taxi with a surly passenger who is in a big hurry to get to the airport. The passenger (your reader) would scream colorful words if you decide to take the scenic route.

So here are ten tips to improve your technical writing.

The 10 tips at a glance

Tip 1: Know your audience.

Tip 2: Have a conversation.

• Pretend you are writing an email to a friend.
• Use simple words.

Tip 3: Know your goals.

• Tell them what you’re going to say and then tell them.
• Wrap up.

Tip 4: Make the organization clear with good headings.

• Make your headings task-oriented.
• Use parallel structure.
• Show sequence.

Tip 5: Assume that your reader has the attention span of a gnat.

• Get to the point.
• Bulleted lists are your friends.
• Break up concepts.
• Use graphics and charts.

Tip 6: Be consistent.

• Just pick a word and stick with it.

Tip 7: Write lively.

• Use the active voice.
• Use action words (verbs).
• Let your personality shine through.
• Avoid Latin.
• Don’t start a sentence with “There…”.

Tip 8: Be precise.

• Stay in the present; don’t use future tense.
• Use the right auxiliary verbs.
• Keep the pronouns clear.
• Don’t anthropomorphize inanimate objects.

Tip 9: Explain enough.

• Explain why you’d want to use anything.
• Catch the pitfalls.
• Examples, examples, examples.
• When saying something odd, back it up.
• Don’t lie or oversimplify.

Tip 10: Read your own stuff.

• Read your docs out loud.
• Get rid of all that dead weight.
• Test your sample code.
• Have someone read your work .

But wait, there’s more! click here to read more….

Security is one of the most important aspect of any web or mobile application. It is a very common practice to encrypt sensitive information like passwords in the database.

Jasypt library is a good and simple solution for any java project to have encryption capability.

Jasypt is a very advanced library with support for integrating with Hibernate, Spring, Spring Security and number of other java frameworks and technologies.

Basic usage example code is as below:

...
BasicPasswordEncryptor passwordEncryptor = new BasicPasswordEncryptor();
String encryptedPassword = passwordEncryptor.encryptPassword(userPassword);
...
if (passwordEncryptor.checkPassword(inputPassword, encryptedPassword)) {
  // correct!
} else {
  // bad login!
}
...

More security: the StrongPasswordEncryptor util class with a much more secure (but slower!) algorithm:

...
StrongPasswordEncryptor passwordEncryptor = new StrongPasswordEncryptor();
String encryptedPassword = passwordEncryptor.encryptPassword(userPassword);
...
if (passwordEncryptor.checkPassword(inputPassword, encryptedPassword)) {
  // correct!
} else {
  // bad login!
}
...

Enjoy your code. Vulab provides hands-on training in java, android, apple ios and many other technologies.

Spring MVC can return data in the JSON format to your front end. You can use jQuery to make ajax requrest to the MVC controller and controller can return the data in json format. Let us see how this can be acheived.

Assuming you are using Maven for dependency management.
Add this dependency to your pom.xml

1

6

<!-- Jackson Dependencies -->
		<dependency>
			<groupId>com.fasterxml.jackson.core</groupId>
			<artifactId>jackson-core</artifactId>
			<version>2.0.0</version>
		</dependency>

Make sure you have enabled mvc in your configuration as below:

1
2

<!-- Enables the Spring MVC @Controller programming model -->
	<mvc:annotation-driven />

In your controller method use the following style of code to return json.

1
2
3
4
5
6
7
8

10
11
12

@RequestMapping(value="/testjson.html", method = RequestMethod.GET)
	public @ResponseBody User getUserInJSON() {

		User user = new User();
		user.setActive(false);
		user.setEmail("test@test.com");
		user.setFirstName("test");
		user.setLastName("user");
		user.setUserId(10);
		return user;

	}

@ResponseBody annotations is the most important annotation in the code below. This annotations is making the framework to convert the user object into json format and return to the front-end.

http://localhost:8080/vulab/testjson.html

When you invoke the controller’s method you will get back output in json format as below:

1

{"userId":10,"firstName":"test","lastName":"user","email":"test@test.com","password":null,"active":false,"roles":[],"phone":null,"interests":[]}

For your reference a code snippet from : User.java code

Spring data projects helps with the following aspects:
Building spring applications with noSQL databases like MongoDB, Redis, Riak, Redis, neo4j
Building spring applications using Map-reduce frameworks like Hadoop
Using Cloud based services and relational databases with spring projects.

Spring Data Jpa is a wonderful solution for any project connecting to relational databases. It will reduce the code written as the JPA repositories will provide Query DSL support as well as CRUD functionality for all domain objects mapped to the DB.
These are the full list of advantages:

• Sophisticated support to build repositories based on Spring and JPA
• Support for QueryDSL predicates and thus type-safe JPA queries
• Transparent auditing of domain class
• Pagination support, dynamic query execution, ability to integrate custom data access code
• Validation of @Query annotated queries at bootstrap time
• Support for XML based entity mapping

The same advantages of Spring Data can be utilized for MongoDB, Redis, Riak, Neo4J.
Apache Hadoop is another important project to watch as it will make the Map-Reduce technology much easier to use by removing any framework complexities.

If you are using any relational database, mongoDB, Redis , Riak or Neo4J, consider integrating Spring Data libraries to your project. Spring Data will reduce the amount of code you write as well as bring in a number of good features.

If you are interested in map reduce with Hadoop, please read this excellent post from Costin Leau from Spring Source.
