Java Viewpoint: "Java Is Still the Mainstream, But..."

Java Developers Need to Look to Their Laurels and Start Innovating Again

The other day I was talking to a coworker about learning Ruby. He said that as a Java programmer the hardest part of learning Ruby was not the syntax nor the dynamic typing. Oh, he could write perfectly correct Ruby, sans semicolons and variable declarations. His problem was that he found himself falling back into his same old Java habits. He felt like he was missing something because his Ruby code always ended up looking pretty much like what he would have written in Java.

This is not a problem that is unique to Java or Ruby or even programming languages. We all have a comfort zone of techniques and habits, our ‘happy place‘ where we feel productive and comfortable. The trouble with the happy place is that if you stay in your happy place too long you will be miserable. The world will move on and there you will be, eyes tight shut, hands over your ears, rocking slowly as you repeat, “I‘m happy, I‘m happy.“

Is Java dead? The buzz at the last software conference I attended, a conference previously full of Java developers and talk, was all about Ruby. The web is filling up with talk about the ‘R‘ word. Yesterday an old friend of mine IM‘ed me to say that he had a new job and his boss wants him to do this Rails thing and did I think it was for real.

Is Java dead? No. Java is still the mainstream. It is blessed with a high performance VM that is installed darn near everywhere. There is an army of experienced Java programmers out there. But the Java world has been in the same happy place for way too long. We in the Java world have been hanging out in the same statically typed, framework driven, XML configured lair for too many years.

We need to start thinking new thoughts:

  • The key to Java is not the language, it is the JVM. If it runs on the JVM it is Java, no matter what the source language was. Ruby has dynamic typing and maybe that is a good thing? Well the Java world has Jython and Groovy and Rhino and Beanshell and soon JRuby. Why aren‘t we making more use of these?

  • One of the most common reactions to the elegance of Rails is “Oh, we could do that in Java.” Well, let us do so with haste, but let us also ask ourselves: Why didn‘t we think of this?

  •  As Bruce Tate has pointed out many times, why does all data taste better in XML? If there is a byte in a forest not wrapped in angle brackets, does it still convey data? Could we Java folks at least think before reaching for the JAXP?

Java isn‘t dead, it‘s probably not even that sick. But the mid life crisis is here and we need to decide if we are going to buy a red convertible or get down to really dealing with our problems.

'Is Java dead?' asks Russ Olsen. No, he answers himself; Java is still the mainstream, and blessed with a high performance VM that is installed nearly everywhere plus there is an army of experienced Java programmers out there. 'But the Java world has been in the same happy place for way too long,' Olsen contends, adding: 'We in the Java world have been hanging out in the same statically typed, framework driven, XML configured lair for too many years.'

Oh jeez, not another Java is dead story. Well, I guess the goal of any publication these days is controversy. The fact is that with an over 20% mindshare (according to Java is the most popular programming language. Should we rest and get complacent? Sure, as long as we continue to build reusable libraries. The only real setback for Java has nothing to do with technology - its the feud with Microsoft. I think, with the failure of C# to gain much of a foothold, Microsoft needs Java.

What we should do is "assume" Java is the language of choice for most development and move forward confidently. The proliferation of languages and variants is too costly and distracting to indulge in. The only real alternatives at this point are c/c++ (too expensive) and vb (too proprietary and awkward) so stop the self doubt, get rid of confusion factors like XML languages or the latest special purpose languages and move on to create real usable, reliable and therefore indispensable libraries. Java isn't perfect but it has all the truly needed features and the popularity & portability to make it the low-risk choice for development. Just do it.

Java is still in incredibly heavy use in larger-scale systems and internal applications. It doesn't need to be "hip", "trendy", or "LAMP". It just needs to do a job, do it well, and be maintainable. It does that (and more), has still proven fairly easy to scale from small projects to very large, and is still a decent (though not terrific) language.

It also plays well with many other solutions, by virtue of numerous scripting languages which target Java bytecodes, as well as native code integration if you simply cannot get by without some piece of C code (although, there goes easy portability - one of the major benefits).

But why should frameworks be intrinsically bad?

Just over a week ago I received a long and loud sustained applause for a presentation I delivered at this year’s Cloud Expo in Santa Clara. I was extremely pleased with the turnout and had some very good conversations with many of the attendees. Over the next few days I had many more meaningful conversations and was not only happy with the results but also learned a few new things. Here is everything I learned in those three days distilled into three short points.
DevOps is about increasing efficiency, but nothing is more inefficient than building the same application twice. However, this is a routine occurrence with enterprise applications that need both a rich desktop web interface and strong mobile support. With recent technological advances from Isomorphic Software and others, rich desktop and tuned mobile experiences can now be created with a single codebase – without compromising functionality, performance or usability. In his session at DevOps Summit, Charles Kendrick, CTO and Chief Architect at Isomorphic Software, demonstrated examples of com...
As organizations realize the scope of the Internet of Things, gaining key insights from Big Data, through the use of advanced analytics, becomes crucial. However, IoT also creates the need for petabyte scale storage of data from millions of devices. A new type of Storage is required which seamlessly integrates robust data analytics with massive scale. These storage systems will act as “smart systems” provide in-place analytics that speed discovery and enable businesses to quickly derive meaningful and actionable insights. In his session at @ThingsExpo, Paul Turner, Chief Marketing Officer at...

The Internet of Everything is re-shaping technology trends–moving away from “request/response” architecture to an “always-on” Streaming Web where data is in constant motion and secure, reliable communication is an absolute necessity. As more and more THINGS go online, the challenges that developers will need to address will only increase exponentially. In his session at @ThingsExpo, Todd Greene, Founder & CEO of PubNub, exploreed the current state of IoT connectivity and review key trends and technology requirements that will drive the Internet of Things from hype to reality.
Two weeks ago (November 3-5), I attended the Cloud Expo Silicon Valley as a speaker, where I presented on the security and privacy due diligence requirements for cloud solutions. Cloud security is a topical issue for every CIO, CISO, and technology buyer. Decision-makers are always looking for insights on how to mitigate the security risks of implementing and using cloud solutions. Based on the presentation topics covered at the conference, as well as the general discussions heard between sessions, I wanted to share some of my observations on emerging trends. As cyber security serves as a fou...
Continuous processes around the development and deployment of applications are both impacted by -- and a benefit to -- the Internet of Things trend. To help better understand the relationship between DevOps and a plethora of new end-devices and data please welcome Gary Gruver, consultant, author and a former IT executive who has led many large-scale IT transformation projects, and John Jeremiah, Technology Evangelist at Hewlett Packard Enterprise (HPE), on Twitter at @j_jeremiah. The discussion is moderated by me, Dana Gardner, Principal Analyst at Interarbor Solutions.
Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
With all the incredible momentum behind the Internet of Things (IoT) industry, it is easy to forget that not a single CEO wakes up and wonders if “my IoT is broken.” What they wonder is if they are making the right decisions to do all they can to increase revenue, decrease costs, and improve customer experience – effectively the same challenges they have always had in growing their business. The exciting thing about the IoT industry is now these decisions can be better, faster, and smarter. Now all corporate assets – people, objects, and spaces – can share information about themselves and thei...
The Internet of Things is clearly many things: data collection and analytics, wearables, Smart Grids and Smart Cities, the Industrial Internet, and more. Cool platforms like Arduino, Raspberry Pi, Intel's Galileo and Edison, and a diverse world of sensors are making the IoT a great toy box for developers in all these areas. In this Power Panel at @ThingsExpo, moderated by Conference Chair Roger Strukhoff, panelists discussed what things are the most important, which will have the most profound effect on the world, and what should we expect to see over the next couple of years.
Discussions of cloud computing have evolved in recent years from a focus on specific types of cloud, to a world of hybrid cloud, and to a world dominated by the APIs that make today's multi-cloud environments and hybrid clouds possible. In this Power Panel at 17th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists addressed the importance of customers being able to use the specific technologies they need, through environments and ecosystems that expose their APIs to make true change and transformation possible.
The cloud. Like a comic book superhero, there seems to be no problem it can’t fix or cost it can’t slash. Yet making the transition is not always easy and production environments are still largely on premise. Taking some practical and sensible steps to reduce risk can also help provide a basis for a successful cloud transition. A plethora of surveys from the likes of IDG and Gartner show that more than 70 percent of enterprises have deployed at least one or more cloud application or workload. Yet a closer inspection at the data reveals less than half of these cloud projects involve production...
Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem" in this scenario: microservice A (releases daily) depends on a couple of additions to backend B (re...
Growth hacking is common for startups to make unheard-of progress in building their business. Career Hacks can help Geek Girls and those who support them (yes, that's you too, Dad!) to excel in this typically male-dominated world. Get ready to learn the facts: Is there a bias against women in the tech / developer communities? Why are women 50% of the workforce, but hold only 24% of the STEM or IT positions? Some beginnings of what to do about it! In her Day 2 Keynote at 17th Cloud Expo, Sandy Carter, IBM General Manager Cloud Ecosystem and Developers, and a Social Business Evangelist, wil...
