NASA and SONY Websites are built using Drupal.
Latest trends in web designing
Design trends often span several years (even decades for some types of design), but Web design is a quickly moving and changing industry where trends come and go quite often.
We’re still working with some of those trends now: responsive web design, flat design, performance and speed, and perfecting the user experience.
We are expecting these trends to show up in the year 2016.
- Navigation and Menus
Navigation and Menus are very important tools of websites, but don’t look trendy, web developers are experimenting on these styles and menus. Hidden navigation has become very popular way to keep it on the website, performing its intended function and not disturbing the UI of the website.
- To scroll or not to scroll
Web developers are experimenting with no scroll type of pages. Just Imagine, how difficult it is to find the content you need which is somewhere in the middle of a very long page? But in no scroll page you get the information you need at a click.
- Designing in modules and components instead of entire pages
Web design is moving toward modular and component design instead of mocking up entire layouts and comps for a particular web page. These components often involve designing how the search function will work, how the navigation will be laid out, etc.
We’ve matured into knowing that we have repeated elements on different screens, and that these elements need to be designed both so that they work independently but can still work with the rest of the site.
Not only are we more concerned about how these components look in terms of design, but they all carry their individual functionalities with it too. Designing with components and modules allows the same functionality to be replicated no matter where it appears on the site.
- Hero images:
Since vision is the strongest human sense, HD hero images are one of the fastest ways to grab a user’s attention. Thanks to advances in bandwidth and data compression, users won’t suffer from slow load times either. One common layout you’ll find is a hero image above the scroll, followed by either zig-zagging sections or a cards-based arrangement.
- Rich Animations
Animations are being used more and more to enhance a site’s visual appearance, making the experience more interactive and entertaining. The animations should be carefully designed, it should be light and fast enough.
Animations can be thought of in terms of two groups:
- Large scale animations. These are used as a primary interaction tool have more impact on users and include effects like parallax scrolling and pop-up notifications.
- Small scale animations. These include spinners, hover tools and loading bars, and don’t require any user input.
- Loading animations
These are used to improve the user experience while loading the data. Loading animations should be kept simple and no sound should be added, the sound can leave a user with bad experience in the site.
- Hover animations
Hover effects give information about a particular object as they hover their mouse on the object.
Pay scales of web designers in India:
The survey from the payscale.com suggests that a web developer with adequate skills earns an average of 4,17,255 INR per annum. The pay varies on your experience and your coding skills. In Bangalore, the pay ranges from 2,36,000 to 7,00,000 INR.

Scope of Java:
This is the well-known fact that java is the best next big thing to come up in IT industry after C++. Since its inception it has surprised the world with the new products and services.
Where Java is used?
1) Android Apps
If you want to see where Java is used, you are not too far away. Open your Android phone and any app, they are actually written in Java programming language, with Google’s Android API, which is similar to JDK. Couple of years back Android has provided much needed boost and today many Java programmers are Android App developer.
2) Server Apps at Financial Services Industry
Java is very big in Financial Services. Lots of global Investment banks like Goldman Sachs, Citigroup, Barclays, Standard Charted and other banks use Java for writing front and back office electronic trading system, writing settlement and confirmation systems, data processing projects and several others.
3) Java Web applications
Java is also big on E commerce and web application space. You have a lot of Restful services being created using Spring MVC, Struts 2.0 and similar frameworks. Even simple Servlet, JSP and Struts based web applications are quite popular on various government projects. Many of government, healthcare, insurance, education, defense and several other departments have their web application built in Java.
4) Software Tools
Many useful software and development tools are written and developed in Java e.g. Eclipse, InetelliJ Idea and Netbans IDE.
5) J2ME Apps
Though advent of iOS and Android almost killed J2ME market, but still there is large market of low end Nokia and Samsung handset which uses J2ME. There was time when almost all games, application, which is available in Android are written using MIDP and CLDC, part of J2ME platform. J2ME is still popular on products like Blu-ray, Cards, Set top boxes etc. One of the reason of WhatsApp being so popular is because it is also available in J2ME for all those Nokia handsets which is still quite big.
6) Embedded Space
Java is also big in the embedded space. It shows how capable the platform is, you only need 130 KB to be able to use Java technology (on a smart card or sensor). Originally Java was designed for embedded devices. In fact, this is the one area, which was part of Java’s initial campaign of “write once, run anywhere” and looks like it is paying up now.
7) Big Data technologies
Hadoop and other big data technologies are also using Java in one way or other.
8) High Frequency Trading Space
Java platform has improved its performance characteristics a lot and with modern JITs, its capable of delivering performance at C++ level. Due to this reason, Java is also popular on writing high performance systems, because Though performance is little less compared to native language, but you can compromise safety, portability and maintainability for more speed and it only takes one inexperienced C++ programmer to make an application slow and unreliable.
9) Scientific Applications
Nowadays Java is often a default choice for scientific applications, including natural language processing. Main reason of this is because Java is more safe, portable, maintainable and comes with better high-level concurrency tools than C++ or any other language.

The Big question is where to learn Java from?
I will make it simple for you. I have done an extensive research and prepared a list from where you can learn Java.
- Company that trains and recruits them after the completion of training.
Find a company that trains you, and will recruit you after the completion of the training. The advantage of joining such a company is you will be working on their ongoing projects. Rather than regular training you will have a chance to see how the ongoing projects are being executed. Finding such a company may be difficult, but it is worth the shot.
- A training academy
Join a certified training academy, they will teach you the Java as per their course. You will be getting the certificate which may or may help for your career. I prefer you take the next method.
- Self- Study:
There are really many pro and cons of self-studying. I will start by citing the cons, you will be unaware of what the trend is currently running in IT industry. Isn’t it always best to be trained by an expert trainer? Obviously it is best. But you can always self-study the topics by the help google or from text books and take up the Oracle Java certification program. I think Java certification has more weightage than the certificates provided by training institute. There are some training institutes whose certificates also have the same weight-age as of the Oracle’s Java certificate program.
Here is the list of books which can help you for your self-studies:

What to look for when you enroll for a CCNA Course

Besides, you should look at the credentials of the institute, whether it has a placement cell or not, how qualified are the trainers and the pedigree of the institute and its history.
