Two to Tango

Sometimes I think no one reads the editorial. Normally I receive maybe no more than fifty comments concerning any editorial. I kid myself that I do a good enough job lining up the content for the magazine that no one has any complaints, and that they post each month's editorial on a wall for all to see. In reality, I hope it doesn't show up on that many dart boards ­ I know programmers.

Our JavaOne issue (JDJ Vol. 4, issue 6) wasn't one of those times. I've been writing about programming for over five years, and I've got to say that the response to my "XML Mambo" column was nothing short of a landslide. I couldn't have selected a more charged topic to write about, a fact I'm very pleased with.

To recap briefly: my column questioned XML as the next "killer app." While I feel XML is important, it's my thought that it's overhyped. In my mind that was the gist of the article.

Now I'm either a genius or a schmuck.

The e-mails came fast and furious: those who thought I was so right ­ XML is just marketing hype ­ and those who thought I was a blithering idiot ­ hadn't I ever tried to code server pages in HTML? (Fact is, no, I haven't. That sounds particularly ill-advised in my opinion.) But from an editorial standpoint I had to stand up and take notice: XML is important to you. Maybe it's the next killer appŠmaybe it isn't. Clearly though, you were concerned about the impact XML would have on the world, particularly the Java community. And so was I.

In fact, we here (here being a virtual kind of thing: I'm in New Jersey, Alan's in Scotland, Ajit's in Texas) at SYS-CON have been having numerous discussions concerning XML. So many that I lose the thread of the topics regularly. One thing we all agree on though is that XML is something we need to cover closely.

Hence this issue. Welcome to our special focus issue on XML. On subsequent pages you'll find numerous articles relating to XML, and to Java. We're exploring the topic, possibly in preparation for bigger things. (Can you say XML Developer's Journal? I knew you could.) Because we know that it's important to you.

Either from a career possibility standpoint, or at least for the impact it will have on your lives as Java programmers. Inside, you'll get more information about XML, as well as the opinions of our sharpest minds here at the magazine.

I'd like to try to set some things straight, though. One, I don't think XML is pointless. To me it's objects without the methods ­ which sounds like a step backward, but may not be, as not every object truly needs methods. Second, I think it will have a big impact on e-commerce and EDI, as it's a simple, powerful way to agree on data transfers between organizations. It may even be a decent way to allow larger companies to interact with Web sites without having to have a human being sitting in front of a browser.

But I still stick to my guns when I say that XML is not the next killer app in the way that Java was. XML won't stop me from programming in Java the way Java stopped me from programming in PowerBuilder and, for others, VB or C++. It's not going to change people's minds about platform-independent coding or free them from the Tyranny of Redmont (I'm not sure Java did either, this is editorial license). Instead, I see XML as the SQL of the next century. SQL is everywhere, but few people point to it as a revolutionary product. XML will be like that. We'll adopt it as a good idea that should have been there in the first place, but it won't truly change our lives as developers.

And that's my opinion. As always, I welcome your comments and will try to respond to them. I hope you find this issue intriguing, insightful and useful.

The buzz continues for cloud, data analytics and the Internet of Things (IoT) and their collective impact across all industries. But a new conversation is emerging - how do companies use industry disruption and technology enablers to lead in markets undergoing change, uncertainty and ambiguity? Organizations of all sizes need to evolve and transform, often under massive pressure, as industry lines blur and merge and traditional business models are assaulted and turned upside down. In this new data-driven world, marketplaces reign supreme while interoperability, APIs and applications deliver un...
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.
Electric power utilities face relentless pressure on their financial performance, and reducing distribution grid losses is one of the last untapped opportunities to meet their business goals. Combining IoT-enabled sensors and cloud-based data analytics, utilities now are able to find, quantify and reduce losses faster – and with a smaller IT footprint. Solutions exist using Internet-enabled sensors deployed temporarily at strategic locations within the distribution grid to measure actual line loads.
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, will explore the current state of IoT connectivity and review key trends and technology requirements that will drive the Internet of Things from hype to reality.
The Internet of Things (IoT) is growing rapidly by extending current technologies, products and networks. By 2020, Cisco estimates there will be 50 billion connected devices. Gartner has forecast revenues of over $300 billion, just to IoT suppliers. Now is the time to figure out how you’ll make money – not just create innovative products. With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data shows "less than 10 percent of IoT developers are making enough to support a reasonably sized team....
You have your devices and your data, but what about the rest of your Internet of Things story? Two popular classes of technologies that nicely handle the Big Data analytics for Internet of Things are Apache Hadoop and NoSQL. Hadoop is designed for parallelizing analytical work across many servers and is ideal for the massive data volumes you create with IoT devices. NoSQL databases such as Apache HBase are ideal for storing and retrieving IoT data as “time series data.”
The IoT market is on track to hit $7.1 trillion in 2020. The reality is that only a handful of companies are ready for this massive demand. There are a lot of barriers, paint points, traps, and hidden roadblocks. How can we deal with these issues and challenges? The paradigm has changed. Old-style ad-hoc trial-and-error ways will certainly lead you to the dead end. What is mandatory is an overarching and adaptive approach to effectively handle the rapid changes and exponential growth.
Today’s connected world is moving from devices towards things, what this means is that by using increasingly low cost sensors embedded in devices we can create many new use cases. These span across use cases in cities, vehicles, home, offices, factories, retail environments, worksites, health, logistics, and health. These use cases rely on ubiquitous connectivity and generate massive amounts of data at scale. These technologies enable new business opportunities, ways to optimize and automate, along with new ways to engage with users.
The IoT is upon us, but today’s databases, built on 30-year-old math, require multiple platforms to create a single solution. Data demands of the IoT require Big Data systems that can handle ingest, transactions and analytics concurrently adapting to varied situations as they occur, with speed at scale. In his session at @ThingsExpo, Chad Jones, chief strategy officer at Deep Information Sciences, will look differently at IoT data so enterprises can fully leverage their IoT potential. He’ll share tips on how to speed up business initiatives, harness Big Data and remain one step ahead by apply...
There will be 20 billion IoT devices connected to the Internet soon. What if we could control these devices with our voice, mind, or gestures? What if we could teach these devices how to talk to each other? What if these devices could learn how to interact with us (and each other) to make our lives better? What if Jarvis was real? How can I gain these super powers? In his session at 17th Cloud Expo, Chris Matthieu, co-founder and CTO of Octoblu, will show you!

Developing software for the Internet of Things (IoT) comes with its own set of challenges. Security, privacy, and unified standards are a few key issues. In addition, each IoT product is comprised of at least three separate application components: the software embedded in the device, the backend big-data service, and the mobile application for the end user's controls. Each component is developed by a different team, using different technologies and practices, and deployed to a different stack/target - this makes the integration of these separate pipelines and the coordination of software upd...
Mobile messaging has been a popular communication channel for more than 20 years. Finnish engineer Matti Makkonen invented the idea for SMS (Short Message Service) in 1984, making his vision a reality on December 3, 1992 by sending the first message ("Happy Christmas") from a PC to a cell phone. Since then, the technology has evolved immensely, from both a technology standpoint, and in our everyday uses for it. Originally used for person-to-person (P2P) communication, i.e., Sally sends a text message to Betty – mobile messaging now offers tremendous value to businesses for customer and empl...
