Party! Party! Party!

Party! Party! Party!

I don't know about you, but these months are shooting by at a tremendous rate of knots. Here we are again, into the latter half of the year...and I was just getting used to being back after Christmas. It's all very exciting, racing up to the day that dare not speak its name: yes, the big millennium turnover. Boy, am I looking forward to that day!

But on to more important matters of state: churning out this month's column. This is the month after the biggest month in our developers' calendar: JavaOne. If I am a good boy and manage to finish the show report for this issue, you'll find it lurking somewhere in these pages not so far away from this column. That said, I shall not bore you twice and make you read the same drivel over again.

As my regular readers will recall, we're always on the lookout for developers who can do a day's work without our having to tell them constantly what Java really is. Well, this month we have a new recruit starting with us, and so far so good. He's performing a sterling job. The frightening thing is that he has a personality, which doesn't fit your typical hard-core programmer. I guess we'll have to beat that out of him!

Anyway, why am I telling you this? Before sending our new soldier to the frontline to battle with client code, we put him on some internal projects that needed attention. Nothing too taxing. Basically he had to create a couple of additional classes based on some established core classes. He performed admirably and well within the time allocated. I asked him how the testing went. He said wonderfully well, that all the methods worked. Fantastic.

Hold on...what do you mean all the methods worked? On closer inspection it transpired that our new man had merely called the top-level methods and never checked for anything going awry internally. Bless him. Such blind faith. Now this wasn't his fault directly. He had never really tested code before, and since his test case worked it didn't occur to him to test a scenario that might be a little out with the necessary parameters.

But who can really blame him? It reminded me so much of me when I started on my long journey to Java fulfillment. I was scared to test my code in case my beautiful creation didn't live up to my expectations. I just assumed - hoped is more like it - that it would stand its ground in all environments. Or was it more laziness? Hmmm...the more I think about it, the more I better leave this thread alone before my client base loses complete faith in me!

That Left-Out Feeling
I know. I promised I wouldn't mention JavaOne, but please excuse me. I have to get this out of my system.

Being located in one of the far-flung corners of the globe, Scotland, you sometimes feel left out. You know, the one that gets picked last for the school football team, or the one that never gets invited to the party. You know there's a whole world going on out there, but you're just never sure that you'll fit in. Well, running the n-ary empire from here, we sometimes feel the party is getting down somewhere else and the world has forgotten all about Java and has moved on without telling us. So when an opportunity like JavaOne raises its head, I make the annual pilgrimage to San Francisco.

It's not for personal gratification, you understand. It's for the good of the company (I just want to get that point across in case any of my directors are reading this and trying to figure out why I have absconded to California for a jolly).

There's really only one reason to attend JavaOne. Ironically, it's not to hear people talk, or to walk around booths packed full of vendors peddling their wares. No. It's to meet people or - as we say in the corporate jungle - "to network."

There's a rich tapestry of individuals that make up this wonderful Java universe we've chosen to partake of, and I had the privilege of meeting some of them. I'll introduce some of the more colorful ones to you here.

For those of you that attended and wondered which one I was, that's an easy one to answer. Think hard. Do you remember up in the Media Mall there were lots of big, stupid-looking costumes walking around, depicting scenes of Java (Java in the loosest sense of the word, let me assure you)? Well, I wasn't one of them. However, I was the one with the Scottish kilt loitering around the SYS-CON Radio panel. You may have been too scared to come up and introduce yourself - and who'd blame you? But for those that were brave enough, I thank you. It was indeed a pleasure to be able to put a face to a lot of you.

One of the first people I had the good fortune to meet and get to know rather well over the course of the week was one Rick Ross. Rick is a man I've shared column space with, being another JDJ columnist himself, but I had never met the man in the flesh. What a character Rick is! After meeting the man, I made a bet with myself that should he ever run for office, not much would stop him. He's a born talker, which is one of the reasons the Java Lobby is so popular. For those of you not aware of the Java Lobby, get yourselves to the Web site,, and join the crusade. I see Rick as the thinking man's Jimmy Hoffa, rallying around us mere mortals, making sure Java is heading on a clear and set course. If you ever get the chance to meet him, pin the bugger down and ask him anything that concerns you about Java. I'll bet my grandmother's left leg that Rick has a thought on it. Go on, try it. And if he seems annoyed, you never read this. We never had this conversation!

But having a blether with Rick was a joy. He has many of the same thoughts that we outpost developers hold. Which assured me that maybe the party wasn't going on without us.

Back to My Pilgrimage
One of the things about developing so remotely is that, unlike our Silicon Valley counterparts, the chance of us literally bumping into the competition is highly unlikely. (Unless, of course, Dolly, our amazing cloned sheep, has had a Java chip implanted in there by those clever scientists at Edinburgh.) That aside, while standing at the SYS-CON booth waiting for something that at this point escapes me, a man sidled up and started to talk to me. I think he was complimenting me on my column, but I could be mistaken. Anyway, the conversation drew to a close and for some reason I asked for his business card. When I read it I was bowled over. It was probably the initial shock at seeing his contact information that has made the first point of contact so blurry. (You know who you are, so if I have this slightly wrong, then please forgive me.)

The card I held before me represented our biggest competitor. First time this ever happened to me. Of course, once I introduced myself and the particular project we competed with them on, he knew who we were. We then went for a sit-down while he fetched his CEO. It was all quite amicable. We danced around one another like male peacocks trying to prise information out of one another. So that's what the enemy looks like....I jest.

I have to give a big thanks to Mary Hancock and Clint Dalton for allowing me to hang with them over a number of evenings. Being European, I felt like a fish out of water at times in the throes of California, so these budding reporters from kept me on the straight and narrow. I'd like to give them full credit for trying. Mary had her camera with her all week and was clicking lots of showpieces. Every so often Mary and Clint attempted to get conclusive pictures of what really lies under a Scotsman's kilt. Well, I can proudly say the legend of what is underneath there remains a mystery.

So meeting people at JavaOne was the most important thing. Be proud of the industry you're in, and make sure you get yourself out there. There are some excellent characters about, and I could fill a whole magazine just chattering about them, but I won't. This would spoil the fun for you. But before I leave this, if you're ever around a Java Lobby meeting or up near Seattle, be sure to look up what have to be the coolest brothers in the world of Java: the Ramadan lads from 4thpass. Mazin and Zeyad are the Java equivalent of Bill and Ted, and I highly recommend you speak to these guys if you ever get the chance.

Mailing List
At JavaOne many of my readers and subsequent mailing-list attendees came up and said hello. They assured me they'd be inspiring the list with many new and varied topics of conversation. With that in mind, here's my monthly plug for the list. To join, send e-mail to [email protected] with subscribe straight_talking-l in the body of the message. From there you'll get instructions on how to participate.

Salute of the Month
There are many salutes I could award this month and some of them I mentioned earlier in this column. But one person I have to thank is Jim Driscoll, from the ranks of management at Sun. Now let me explain this. I met Jim in person over a year ago, and had been in constant e-mail contact with him for around eight months earlier than that. Jim is one of the original Java Servlet architects, and it is through this that we had gotten to know one another. For me, Jim was the embodiment of what we perceive a Silicon Valley geek to look like: long hair, unshaven, knee-deep in code and always going somewhere to check his e-mail. Well, I nearly didn't recognize him when he came up to me at JavaOne. He's gone all corporate. The hair is cut, the face is shaved and he's no longer coding. He's management now, climbing that corporate ladder. Jim's professional coding days are gone and he's now resigned to watching as others wrestle with the joys of threads and other goodies Java has hidden up her sleeve. So Jim, we salute you for a job well done. May the rung above you always be free!

Book Review
Last month I promised you a review of Larry Ellison's book once I finished it. Well, I finished it, and what a read it turned out to be! I can't even begin to tell you the sort of antics our man at Oracle has been up to.

Regular readers will know the problems I (and many of you) experienced with Oracle's JDBC drivers. Now I know why. If you read this book be prepared for an amazing tale. I was keen to learn if the contents of the book were true so I went off to the Oracle booth at JavaOne to get some insider information. I have to say I am rather impressed by the way none of the Oracle people I spoke to had any idea the book even existed, let alone the contents. They acted dumb very well. Or maybe they weren't acting, because the same people had never heard of the magazine you're holding in your hands now - the biggest Java circulation magazine in the world and they had never heard of it. Hmmm, not convincing, methinks. I think the brainwashing at Oracle has gone a little too far and way too much information has been erased. But I did manage to speak to some ex-Oracle employees, including a couple that actually were mentioned in the book, and they assured me it's true. So all I can say is read it, and get back to me on our mailing list. I'd love to talk about it.

Now that I'm safe and sound back in my corner here in the lowlands, I can start being paranoid again about the party that no one is inviting us to. Keeping my eye on these supercloned Java sheep, I bid you farewell. Catch you next month.

@ThingsExpo Stories
I recently attended and was a speaker at the 4th International Internet of @ThingsExpo at the Santa Clara Convention Center. I also had the opportunity to attend this event last year and I wrote a blog from that show talking about how the “Enterprise Impact of IoT” was a key theme of last year’s show. I was curious to see if the same theme would still resonate 365 days later and what, if any, changes I would see in the content presented.
Cloud computing delivers on-demand resources that provide businesses with flexibility and cost-savings. The challenge in moving workloads to the cloud has been the cost and complexity of ensuring the initial and ongoing security and regulatory (PCI, HIPAA, FFIEC) compliance across private and public clouds. Manual security compliance is slow, prone to human error, and represents over 50% of the cost of managing cloud applications. Determining how to automate cloud security compliance is critical to maintaining positive ROI. Raxak Protect is an automated security compliance SaaS platform and ma...
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....
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.
With major technology companies and startups seriously embracing IoT strategies, now is the perfect time to attend @ThingsExpo 2016 in New York and Silicon Valley. Learn what is going on, contribute to the discussions, and ensure that your enterprise is as "IoT-Ready" as it can be! Internet of @ThingsExpo, taking place Nov 3-5, 2015, at the Santa Clara Convention Center in Santa Clara, CA, is co-located with 17th Cloud Expo and will feature technical sessions from a rock star conference faculty and the leading industry players in the world.

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...
In his keynote at @ThingsExpo, Chris Matthieu, Director of IoT Engineering at Citrix and co-founder and CTO of Octoblu, focused on building an IoT platform and company. He provided a behind-the-scenes look at Octoblu’s platform, business, and pivots along the way (including the Citrix acquisition of Octoblu).
In his General Session at 17th Cloud Expo, Bruce Swann, Senior Product Marketing Manager for Adobe Campaign, explored the key ingredients of cross-channel marketing in a digital world. Learn how the Adobe Marketing Cloud can help marketers embrace opportunities for personalized, relevant and real-time customer engagement across offline (direct mail, point of sale, call center) and digital (email, website, SMS, mobile apps, social networks, connected objects).
We all know that data growth is exploding and storage budgets are shrinking. Instead of showing you charts on about how much data there is, in his General Session at 17th Cloud Expo, Scott Cleland, Senior Director of Product Marketing at HGST, showed how to capture all of your data in one place. After you have your data under control, you can then analyze it in one place, saving time and resources.
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...
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...
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.
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 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.
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...
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...
