We see this “Is Java out of business?” question pop up year after year. They say that Java is the least feature-rich language of the popular languages on the JVM and the slowest to move on new features in the last decade. There are also people who believe that because so many new JVM languages are being invented is proof that the Java language is lacking and that Java is no longer meeting the needs of many developers. And yet, by all external markers, Java is alive, well, and growing.
Here are several proofs for it:
1. TIOBE ranked Java as its top language of 2015 currently shows it enjoying 5% growth in use since 2014, more than any other programming language.
2. RedMonk has recently published the latest edition of its bi-annual list of the top programming languages. Compiled with the help of data obtained from GitHub and StackOverflow, this list tells us about the usage and discussion of a language on the web. Just like the previous years Java is among the top of the programming languages.
3. Further, the PYPL Index, which ranks languages based on how often language tutorials are searched on Google, shows Java clearly out in front with 23.9% of the total search volume.
Since Java first appeared it has gained enormous popularity. Its rapid ascension and wide acceptance can be traced to its design and programming features, particularly in its promise that you can write a program once, and run it anywhere. Java was chosen as the programming language for network computers (NC) and has been perceived as a universal front end for the enterprise database. As stated in Java language white paper by Sun Microsystems: “Java is a simple, object-oriented, distributed, interpreted, robust, secure, architecture neutral, portable, multithreaded, and dynamic.”
So here are the most common and significant advantages of Java that helped it to take its high position in a quite competitive environment of programming languages:
- Java is easy to learn.
Java was designed to be easy to use and is therefore easy to write, compile, debug, and learn than other programming languages.
- Java is platform-independent.
One of the most significant advantages of Java is its ability to move easily from one computer system to another. The ability to run the same program on many different systems is crucial to World Wide Web software, and Java succeeds at this by being platform-independent at both the source and binary levels.
- Java is secure.
Java considers security as part of its design. The Java language, compiler, interpreter, and runtime environment were each developed with security in mind.
- Java is robust.
Robust means reliability. Java puts a lot of emphasis on early checking for possible errors, as Java compilers are able to detect many problems that would first show up during execution time in other languages.
- Java is multithreaded.
Multithreaded is the capability for a program to perform several tasks simultaneously within a program. In Java, multithreaded programming has been smoothly integrated into it, while in other languages, operating system-specific procedures have to be called in order to enable multithreading.
Nonetheless things changed since the time when Java was created. In the recent years, many important languages have appeared and left an impact on the technology world. Due to their simplicity and user-friendliness, they have managed to surpass the more established languages. So we tried to make a list of reasons why Java is going to stay on the grind in the nearest future:
1. Java is time-proved.
You generally need a strong reason to switch from a language you’re currently using: it requires time to practice and learn new languages, and you have to be confident that the language you’re considering switching to will be supported in the long term. Nobody wants to build software in a language that will be obsolete in five years’ time.
2. JVM and the Java Ecosystem.
The Java Virtual Machine, or JVM. compiles programs into bytecode, which is then interpreted and run by the JVM. Because the JVM sits above your specific hardware and OS, it allows Java to be run on anything, a Windows machine, a Mac, or an obscure some flavor of Linux.
The big advantage granted by the JVM is in this increased compatibility and the stability it affords. Because your application runs in the VM instead of directly on your hardware, you can program said application once and trust that it is executable on every device with a Java VM implementation. This principle is the basis for Java’s core messaging: “Write once, run everywhere.” And it makes Java applications very resilient to underlying changes in the environment.
3. Java and the Internet of Things.
“I really think Java’s future is in IoT. I’d like to see Oracle and partners focused on a complete end-to-end storage solution for Java, from devices through gateways to enterprise back-ends. Building that story and making a success of it will help cement the next 20 years for Java. Not only is that a massive opportunity for the industry, but also one I think Java can do quite well,” said Mike Milinkovich, Executive Director of the Eclipse Foundation.
Oracle agrees. Per VP of Development Georges Saab, “Java is an excellent tech for IoT. Many of the challenges in IoT are many of the challenges of desktop and client Java helped address in the 1990s. You have many different hardware environments out there. You want to have your developers look at any part of the system, understand it and move on. Java is one of the few technologies out there that lets you do that.”
Thus, Java might have its detractors, and some of their arguments might even be reasonable. Nonetheless Java has evolved a lot since its inception, holds the lead in many areas of software development and has more prospects for the future. So, in our opinion, its survivability is not in doubt.
And what do you think? Is Java going to become one of the dead languages? Or it has all chances to survive? Feel free to share your thoughts in comments below!

Today, Node.js offers one of the most innovative solutions to building servers and web/mobile applications. Its single-threaded event looping and asynchronous, non-blocking input/output processing feature distinguishes it from other runtime environments. Its scope is increasing fast with valuable contributions from developers’ community and other technology giants. Right now, several performance-driven frameworks are being developed using primary principles and approaches of Node.js. These frameworks have extended the functionality of Node.js to a great extent and have also built newer features.
In this article let’s have a look at the frameworks associated with Node.js so that you can choose the one you like.
Express is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications. With a myriad of HTTP utility methods and middleware at your disposal, creating a robust API is quick and easy. Express provides a thin layer of fundamental web application features, without obscuring Node.js features that you know and love. Many popular frameworks are based on Express.
Sails is the most popular MVC framework for Node.js. Sails makes it easy to build custom, enterprise-grade Node.js apps. It is designed to emulate the familiar MVC pattern of frameworks like Ruby on Rails, but with support for the requirements of modern apps: data-driven APIs with a scalable, service-oriented architecture. It’s especially good for building chat, real-time dashboards, or multiplayer games; but you can use it for any web application project – top to bottom.
Hapi.js is a powerful Node.js web framework for building APIs and other software applications. The framework has a robust plugin system and numerous key features, including input validation, configuration-based functionality, implement caching, error handling, logging and more. Hapi.js is used for designing useful applications, such as Postmile, a collaborative list making tool. Besides, it is used for providing technology solutions by several large-scale websites, such as Disney, Concrete, PayPal, Walmart and more.
Koa is a new web framework designed by the team behind Express, which aims to be a smaller, more expressive, and more robust foundation for web applications and APIs. Through leveraging generators Koa allows you to ditch callbacks and greatly increase error-handling. Koa does not bundle any middleware within core, and provides an elegant suite of methods that make writing servers fast and enjoyable.
Meteor.js is a real-time application designed to build Web apps that constantly synchronize with the server. Your changes to templates and data flow from the server to the browser automatically. The redrawing and the updating are handled directly by the underlying framework. This works, by the way, in both directions. Your browser code can make changes or write data as if the database is right there. The synchronization happens in the background.
Derby.js is a full-stack MVC framework built for establishing a more solid routine towards creating modern web applications without the need to write complicated code. With Derby you can easily build real-time applications that will run simultaneously in the Node.js server and the browser. The Racer Engine that Derby enables for developers to use is a powerful way of synchronizing your browser, server and database data in real-time amongst all three mediums, enabling you and your app users to experience a true real-time experience. Racer supports offline usage and conflict resolution out of the box, which greatly simplifies writing multi-user applications.
Not every application requires full support for a browser. Restify is one of the server-side frameworks designed to serve up data and only data through an API. You fire it up and out comes JSON to everyone who shows up.
Restify places special emphasis on debugging and profiling so that you can drill down and optimize the performance of your server. DTrace is well-integrated and supported to make it possible to watch what happens and when it might go wrong. Restify is available from GitHub under a very basic license that requires little except a notice of copyright.
Web and apps development landscape is changing very fast and developers are shifting to frameworks aiming at quick and clean project delivery. The biggest plus of using node frameworks is that they provide high level readymade structure and you can focus on scaling your application instead of spending efforts in building and defining the basics.
Let us know your experience with Node.js frameworks via comments. Perhaps there are any «new comers» that deserve our attention?

It’s not a secret that technology does not stand still and every year gadgets are becoming smarter and the developers are trying to surprise users and make something incredible. Probably, one of the most expected smartphone of this year – is the new iPhone 7. It not only possesses all the necessary functions, but also belongs to the category of image devices.
As we have already known Apple will release its next-generation iPhone in a week, and with a launch date fast approaching, details about the new device have been leaking out at a rapid pace. As with most iPhone launches, we’ve seen a slew of rumors that have given us a solid look at what we can expect to see when Apple unveils its new iPhone on September 7.
Of course, as with any rumor cycle, we have seen some conflicting information, so there will still be an element of surprise when Apple CEO Tim Cook and other Apple executives debut the 2016 iPhone.
Well, let’s have a brief look of what we can expect from new iPhone 7.
Since the 3GS launched in 2009, Apple has used an alternating “S” naming formula to mark years where the iPhone does not receive a major redesign, saving its numbered upgrades for years where design changes are introduced. Releases have been as follows:
2007 – iPhone
2008 – iPhone 3G
2009 – iPhone 3GS
2010 – iPhone 4 (new design)
2011 – iPhone 4s
2012 – iPhone 5 (new design)
2013 – iPhone 5s
2014 – iPhone 6 and iPhone 6 Plus (new design)
2015 – iPhone 6s and iPhone 6s Plus
The next-generation iPhone is expected to be called the iPhone 7 and since we are expecting Apple to continue offering two versions of the iPhone – with 5.5 and 4.7-inch displays – we will also see an iPhone 7 Plus.
Every rumor we’ve heard about the iPhone 7’s look suggests Apple is aiming to make the iPhone 7 up to 1mm thinner, removing the headphone jack would be one way to help achieve this, forcing music fans to use wireless Bluetooth headphones, or headphones that connect via the Lightning port, or an adaptor, but other rumors suggest the iPhone 7 and 7 Plus will have a body that is the same thickness as the iPhone 6s.
A redesigned home button was one of the most active topics in the early iPhone 7 prediction conversation. The iPhone 7 would have a “Force Touch” home button. So instead of a physical mechanism, Apple will use its ‘Force Touch’ technology and a motor inside the iPhone to provide the sensation that the button is being physically depressed, similar to the “Force Click” touch pad included on the latest model MacBooks.
Many sources are expecting a significant step up in quality with the iPhone 7’s camera. New evidence appears to suggest that both new iPhone 7 models will have optical image stabilization capabilities. But a steady stream of sources have reported that the dual camera would likely be included on the 5.5-inch-screen iPhone 7 Plus and/or Pro and probably not the standard 4.7-inch-screen iPhone 7. The dual cameras in the iPhone 7 Plus will reportedly use two sensors to capture separate photos with different color patterns, merging them together for one final photograph. Capturing two images at once and merging them is expected to result in brighter, more detailed photos and better zoom functionality.
It’s also going to have faster processor, as the new version is expected to run on a new A10 chip that could be 50 per cent faster than the current A9X, with 3GB of RAM and a 2.37GHZ processor. Numerous sources have suggested that the phone will have 3GB of RAM, where the current model has 2GB.
As battery life remains one of the biggest complaints that users have against the iPhone, the new version will have a 1735 mAh capacity battery and the iPhone 7 Plus a 2810 mAh one – up from 1715 mAh and 2750 mAh respectively.
We can expect that Apple will continue on its path of introducing more powerful, efficient devices with each design iteration. The iPhone 7 and iPhone 7 Plus are expected to include next-generation A10 processors manufactured by TSMC. Internal storage space is getting a boost, with entry-level devices expected to start at 32GB instead of 16GB, and up to 256GB of storage may be available.
What is more, a part leak suggests the iPhone 7 could include dual SIM trays to allow the device to send and receive calls and messages from multiple phone numbers. Dual SIM trays would also allow the iPhone 7 to work with multiple carriers at the same time, ideal for traveling.
Another possible advantage of the new iPhone may be full waterproofing. Instead of adding armour to the outside of the iPhone to protect it from water, the method would coat electronic components found inside the iPhone in a protective waterproof material that would prevent them from getting damaged should water find its way in. If waterproofing the internals of the iPhone 7 doesn’t sound impressive enough to you, the next rumour might. It was published that the iPhone 7 could be waterproof – but not by creating a watertight body, or even waterproofing the internals. Instead, the patent suggests that the iPhone could dry itself by pumping water (or any other liquid, for that matter) out of the device via its speaker grills. Pretty cool, eh?
Well, my review is coming to the end. I hope you have found this information useful.
What do you think about these new features? Please feel free to share your thoughts with us. Thank you in advance!

Wearable tech devices, such as smart watches and bracelets, have firmly stepped into our everyday life and accompany us in different spheres of life. And who knows, we may soon witness the next tech revolution in the wearable world.
Microsoft Research and MIT Media Lab PhD students have teamed up to create the next level of wearable: temporary smart tattoos.
The technology is named DuoSkin. These tattoos consist of artistic arrangements of conductive gold and silver leaf, plus tissue-thin electronics. Users can apply the tattoo to their body with a wet cloth, similar to any other temporary tattoo.
The fabrication process is fairly simple: first, you design a stencil with any graphic design software, and cut the pattern out of tattoo paper and vinyl. Then you place the gold leaf layer on top to create conductivity, and attach surface-mount electronics.
Smart tattoos can be used for several purposes. Firstly, the tattoo can act as an interface that can be used, for example, as a trackpad or a button to remotely control devices. It may be quite demanding in the near future as our devices get smaller and smart tattoos could provide some additional auxiliary area, without carrying a larger device. Secondly, they can track and show users information about themselves, for example they can change color depending on the user’s mood or show body temperature. A third possible function is wireless communication. The tattoo could include an NFC (near field communications) tag, an electrical component that includes small microchips to store data that can be read by phones or other NFC devices nearby. In the near future, the technology could serve as a substitute for identification, subway cards, etc.
Cindy Hsin-Liu Kao, the lead researcher, calls DuoSkin a “project” and not a product or prototype. Others may use this information as a basis to create their own personalized on-skin wearables.
Lets’s think a bit out of the box:) The future presented in some fantastic films is about to come to reality: not more physical devices but different tattoos and built-in chips:) Аnd what do you think about smart tattoos? Will they change the wearable world or will soon be forgotten?
