Hottest IT jobs 2016

 hottest new jobs in IT

Hottest IT jobs 2016

When CompTIA conducted an intensive examination of the IT employment market last year, it uncovered demand for jobs whose titles would have been meaningless only a year or two ago: augmented reality designer, Internet of things architect, container developers.

That’s no surprise, given that the IT job market is in constant flux, with new technologies emerging so quickly that hiring managers struggle to define those positions -- let alone give them a title. IBM, for example, has a director of blockchains, and Ford Motor is among many companies looking for GPU cluster engineers.

At the same time, traditional IT jobs are morphing, requiring new abilities, says Tim Herbert, senior vice president and researcher at CompTIA. Network admins, for example, must learn cloud skills, and security specialists are using machine learning to defend their networks.


Computer security incident responder

Cyber security specialist has long been on the hot jobs list, broad understanding of security information and event management (SIEM),
SIEM combines a number of functions into a single system and centralizes event logs and other security-related documentation for analysis. The information resides within the SIEM, but leveraging it means knowing what questions to ask, and few people have that skill,
Foote, agrees, saying “without a doubt, a cyber security skills gap has developed on a global basis.” The increasingly sophisticated nature of cyber attacks and the ability to use new technologies such as machine learning algorithms to analyze, understand, and counter those threats has fundamentally changed the nature of the job, which now requires the ability to cull evidence from a wide range of sources, not SIEM alone.
Skills you’ll need in order to be considered include a knowledge of networking fundamentals (all OSI layers), protocols and packet analysis, encryption and tokenization technologies, and experience writing PL/SQL or SQL scripts.
Since this job is built on a foundation of conventional skills, you’ll also need information security certifications such as CISSP, SANS, CEH, or related certifications.

Internet of things architect

One billion, 2 billion, who knows how many billions of devices will be connected to the red-hot Internet of things? Even if those estimates are wildly overstated, the IoT is top of mind for many innovative companies -- and not only startups.
Verizon, for instance, recently advertised for what it calls an “IoT solutions architect.” Among other skills, the applicant should have experience in “managing delivery of complex solutions involving IoT, M2M [machine to machine], cloud, security, professional services, and SaaS,” in addition to “strong technology marketing and analytical skills.”
It’s worth noting that Verizon wants its architect to have nontechnical business skills as well: “Must possess financial management skills needed for forecasting, pricing, and margin analysis. Professional presentation and [communication] skills to address all levels of the enterprise to include client senior executives.”
That requirement tracks with an important trend: Information technology departments are becoming less of a service organization and more of a line of business that can add revenue and business opportunities to the entire enterprise.

Virtual reality engineer

Virtual reality is no longer the sole province of game makers. That means someone with the right experience and skills can write a ticket to places as diverse as The New York Times, one of the first newspapers to begin using VR (and Google Cardboard) as a storytelling tool, or startups such as Lucid VR, a developer of 3D cameras.
Here’s a list of skills Lucid says you’ll need: Objective-C, C++, Computer Vision, C, computer graphics, mobile application development, OpenGL ES, C#, OpenGL, DirectX, WebGL, and digital image processing. There are more VR-related jobs posted on AngelList and you’ll find postings for a few VR engineers by CyberCoders, a staffing agency in Seattle.
Don’t overlook established companies working on mobile if you’re interested in VR. Samsung, for example, recently announced two new phones, but what drew more attention at the Mobile World Congress was its Gear 360, a camera for recording virtual reality videos for its Gear VR headset.
Although investment banks frequently overhype new technologies, it’s worth noting that Goldman Sachs predicts that virtual reality will generate $110 billion compared to television’s $99 billion in 10 years. Even if that estimate is too bullish, it is clear that serious money is pursuing virtual reality technology and there will be opportunities for skilled IT workers to exploit.

GPU cluster engineer

GPU computing improves application performance by offloading compute-intensive portions of the application to the GPU, while the remainder of the code still runs on the CPU. That advantage is key to companies like Facebook, China’s Baidu, and Experian that deal with enormous data sets.
Facebook’s Big Sur runs the social networking company’s machine learning servers and is heavily reliant on GPU clusters, which can be more efficient than conventional CPUs for machine learning and other tasks. Facebook CTO Mike Schroepfer says the GPU-based system is twice as fast as conventional solutions.
Experian, with its massive data stores, also uses GPU clusters, but because it is a new technology, finding engineers with GPU experience is difficult, says Experian’s Haller. “Provisioning clusters is one thing, but writing code to run on it is another. You can download software that does it, but that’s inefficient,” he says.
In something of a new technology twofer, Ford Motor is looking for GPU engineers to work on its driverless car program. The list of necessary skills and duties fills an entire computer screen, and the minimum skills needed include: “1+ years [experience with] GPU, parallel programming tools and language extensions etc.,” as well as a broad array of programming skills, among them C/C++, Perl, Python, Java, OpenGL, OpenCV, CUDA, MATLAB, and more.

LED Bulb could connect you to Internet

LED Bulb could connect you to Internet

LED Bulb could connect you to Internet

Imagine an LED bulb doubling as an access point for connecting to the Internet and ordinary light being used as a medium to carry data.A whole new world wherein a bulb would not only give us light but also help us access the Web might not be too far away, if a new technology called Li-Fi (or Light-Fidelity) goes mainstream. The use of the light spectrum for Li-Fi overcomes the issues in traditional wireless communication, like the shortage of spectrum and network disruption because of interference. In Li-Fi, anyone who has access to light can access the Internet. The system also allows users to move from one light source to another without losing their network connection.
What about connecting to the Internet in the night? The stream of photons can be reduced to a minimal level that won’t produce visible light but enough to carry data.
LED Bulb could connect you to Internet


1.What is Li-Fi?

Light-Fidelity is a new technology that uses light waves, instead of radio frequency waves, as a medium to carry data. An improvised LED bulb functions as a router

2.How does Li-Fi work?

A.>An ordinary off-the-shelf LED bulb connected to a device, which in turn is connected to the Internet.
B>The Internet data flows in via the device into the bulb, and is carried by light waves.
C>At the other end, light waves carrying the Internet data falls on a receiver or a dongle which is connected to the computer.

3.Benefits of Li-Fi


  •  Visible light spectrum is available in plenty, unlicensed and free to use
  • Double benefit of a bulb giving us light as well as internet access
  • Low interference leads to very high data speed
  • Li-Fi works under water as well
  • Not harmful, unlike RF that can interfere with electronic circuitry
  • Light won’t pass through walls, making eavesdropping nearly impossible
  • LED illumination is already efficient and data transmission needs very little additional power.
  • It can achieve about 1,000 times data density of Wi-Fi, since light can be contained in an area

PROGRESS CARD: 

JULY -2011: Harald Haas coins Li-Fi at TEDGlobal
JAN-2012 :PureLifi Founded 
SEP-2013: Launch of first product Li-1st
DEC-2014: Second Product Li-Flame Developed
NOV-2015: Prof.Haas demonstrates Li-Fi using solar cell at TEDGlobal.
DEC-2015: Latest product LiFi-X Developed.

Why Java is Still #1

 Why Java is Still #1


It’s the start of 2016, which means that we’ve now finished the “20 Years of Java” celebrations. Actually, although the announcement about Java (and the HotJava browser, which did not enjoy quite the same success) was made publicly on May 23rd, 1995, the first official release of the JDK was on January 23rd, 1996. You could justifiably claim that Java is only now turning twenty. There have been numerous retrospectives on Java, but I thought what would be interesting to look at is the success of Java in its twentieth year.

It’s difficult to accurately measure the popularity of programming languages, but one of the generally accepted surveys is the TIOBE index. This tracks language references through a variety of search engines as well as Google Blogs, Wikipedia and even YouTube. (In writing this entry I learnt something new, which is that TIOBE is actually an acronym for “The Importance Of Being Ernest,” the play by Oscar Wilde. Not sure what that has to do with programming languages, but there you go.).

Looking back at the results over the last fifteen years Java has consistently been either number one or two. Java has jostled for position with C, which was consistently the most popular before Java was launched (how things change: back in 1986 Lisp was number two and Ada was number three). TIOBE have also just announced that Java is their “Programming Language of the Year” for 2015. A great achievement, especially as it was also given the award ten years ago.

As another measure of popularity, Oracle frequently likes to quote the statistic that there are nine million Java developers in the world. If you want a chuckle check out this JAXenter article, which gives some details of how they got to this number. Regardless of the details I think we can all agree there are literally millions of Java developers around the world.

The question to ask is why does Java continue to be so popular? I think there are a number of reasons for this; let’s just highlight four:

1. Practicality

James Gosling has described Java as a “blue collar” programming language. It was designed to allow developers to get their job done with the minimum of fuss, whilst still enabling developers to pick up someone else’s (or even their own) code at a later date and understand what it’s supposed to do. Sure, you can write unreadable code in Java, just as you can in any language, but with good coding conventions it is more readable than many other languages.

2. Backwards compatibility

Sun and subsequently Oracle have made huge efforts to ensure that code written for one version of Java will continue to run unchanged on newer versions. Although this hasn’t always been the case (assertions in Java SE 1.4, enumerations in Java SE 5) and it has sometimes led to implementations that could have been better without compatibility (generics) it is a very compelling feature for developers. There’s nothing worse than taking code that works and having to change it to make it work on a newer version of the platform. That’s just wasted time.

3. Scalability/Performance/Reliability

With over twenty years and thousands of man-years of development, Java is a rock-solid platform that performs on a level that can match or even exceed that of native code (thanks to some of the optimisations made by the JVM using dynamic rather than static code analysis). When it comes to scalability, just look at some of the large enterprises using Java: Twitter (who moved off Ruby-on-Rails to the JVM because RoR wouldn’t scale), Spotify, Facebook, Salesforce, eBay and, of course, Oracle. Hadoop, Cassandra and Spark, the basis of most big data projects, are either written in Java or Scala and run on the JVM. If you want scalability and performance, Java and the JVM is an obvious choice.

4. Freshness

To me this is the big one. Looking at the TIOBE graph there is a significant upswing in Java popularity since October 2014, which is shortly after the launch of JDK 8. JDK 8 was a big change for developers using Java because of the introduction of Lambda expressions and the streams API. Suddenly Java developers could do things in a more functional way without having to learn a whole new language like Scala. These features also make it potentially much simpler to take advantage of multi-core/multi-processor machines without having to write lots of complex and potentially error prone multi-threaded code. With project Jigsaw scheduled for delivery in JDK 9 we’ll see modularity make big enterprise applications much easier to build, deploy and maintain. There are already plans for new language features, like value types, in JDK 10.
