Latest Blogs from JAVA Developer's Journal
The other day I found myself in a discussion with a prospect regarding the merits of capturing complete stack traces for every transaction that flowed through their production system. You see AppDynamics doesn’t do that; we capture problematic business transactions, and this bloke seem...
Yesterday, I decided to re-write with lambdas one of the example I use while explaining polymorphism during my Java trainings. I realize that lambdas promote functional style of programming, while polymorphism is one of the crucial object-oriented features. Still, I decided to try mixi...
We're launching the "Tap In Open Forum": a new series of blog posts where we detail a current topic being discussed in the software development and testing community and invite you to participate in an open discussion with our best and brightest here at Skytap. Feel free to share your ...
Since the birth of Hadoop in 2005-06, the way we think about storing and processing information has evolved considerably. The term “Big Data” has become synonymous with this evolution. But still, many of our customers continue to ask, “What is Big Data?”, “What are its use cases?”, and...
We often get asked “Should I use GridFS for file storage with MongoDB”. As with most things, the answer is a staunch “it depends”. GridFS looks like a great idea on paper - a virtual filesystem held within MongoDB which allows for larger than 16MB files to be held, synced and replicat...
One of the benefits of SDN is centralized control. That is, there is a single repository containing the known current state of the entire network. It is this centralization that enables intelligent application of new policies to govern and control the network - from new routes to user ...
Good morning! Or evening, if you happen to be reading this on the other side of the world. Our topic for today is the internet. What? You already know about the internet? No, no, I don’t mean that internet, the boring old one you use to access YouTube and send Facebook updates, e...
I was recently reading Freakonomics’ authors Steven D. Levitt & Stephen J. Dubner’s latest book, Think Like a Freak, and passed over a quote that really resonated with me: So rather than address their root causes, we often spend billions of dollars treating the symptoms and are left t...
This week in the States, the Nation celebrates it’s Independence and many people will be attending or setting off their own fireworks show. In Hawaii, fireworks are shot off more during New Year’s Eve than on July 4th and there is even Daytime Fireworks now. Cloud computing is explo...
If LinkedIn profiles are any indication, User Experience (frequently shortened to UX) is the new orange. Indeed, across all manners of technology, there is an increasing focus on improving user experience. Driven in part by Apple’s success on the consumer side, it would appear that IT ...
In the video at this link and embedded below I provide some context on new approaches to data can enhance outcomes for public sector organizations, with a focus on real world use cases. I also mention key requirements which apply at most government organizations for their data and how ...
As revenues from traditional voice and messaging channels continue to dwindle, operators are reassessing their role in the digital communication value chain, and defining what value they can bring to their customers. Of course "customers" increasingly includes partners as well as end ...
Inarguably one of the drivers of software-defined architectures (cloud, SDDC, and SDN) as well as movements like DevOps is the complexity inherent in today's data center networks. For years now we've added applications and services, and responded to new threats and requirements from th...
Welcome to the fourth era of digital. The first three periods or ages or phases — call them what you like — were each defined clearly by transformative events. First, the dawn of the personal computer age in April 1977 with the debut of the Apple II (and validated in August 1981 with...
Here’s a simple Java program that I wrote to test Swing GUI in Java 8 (I use JDK 1.8.0_05-b13):   import javax.swing.JFrame; import javax.swing.JButton; public class HelloWorld extends JFrame { public static void main(String[] args) { JFrame myWindow = new HelloWorld(); // C...
By now we’ve seen plenty of cost justification on the efficiency of using cloud infrastructure. You can easily Google “Cloud Computing Value” and get a stack of analyst and vendor reports. Or just pop open Amazon’s AWS value calculator and plug in some numbers. There are huge one-time ...
Some people believe good or bad things always happen in threes. I believe you will always be able to find three (and probably more) things that are good or bad and somewhat related, but sometimes I get surprised by the apparent coincidental appearance of several closely related “things...
As an individual I can decide which platform I would like to target with my shiny new application, but when working for a company we have to target both industry leaders at the same time. Although I like a good challenge, I am really glad the mobile world now only consists of iOS and A...
72%. That's an estimate of how much of the IT budget is allocated to simply keeping the lights on (a euphemism for everything from actually keeping the lights on to cooling, heating, power, maintenance, upgrades, and day to day operations) in the data center. In a recent Forrester Res...
Ask two politically opposed people in any given country about the causes of the country’s problems, and guess what? Each will give you an answer filtered through their world-view. Through what they know, and what they believe. That is not to say one is right and one is wrong, both simp...

The announcement this week that Facebook is acquiring Pryte should make operators sit up and take notice. The communications landscape is evolving at break neck speed and operators need to start shouting about where they can bring value, before they get drowned out by the noise. Beca...
By Richard Stiennon When I predicted a surge in growth in the IT security industry last year (24% CAGR for ten years leading to a $640 billion industry by 2023) I pointed out that encryption would lead the way and that that was not possible without good key management. Perhaps because ...
About 8 years ago at my previous employer we started a project related to Autonomic Networking. Autonomic Networking is modeled after Autonomic Computing, an IBM initiative from the early 2000s, targeted at creating self managing computing elements. The network version intends to creat...
by Joseph Rickert For the past year or so we have been plotting the location of R user groups around the world using code (Download RUGS) adapted from a solution that Sandy Muspratt originally posted on Stack Overflow. In last week’s post, we made a modest improvement to our presentati...
Consider the possibility that a small innocuous code change could go undetected, promoted through Development & QA, and then have catastrophic effects on performance once it reaches production. The environmental variants need to be minimized and closely monitored to prevent the anomalo...

Some of you will remember Caddyshack - that campy '80s movie in which Chevy Chase often offered crazy advice, like "be the ball." For those of you who don't (because you're too young or were living under a rock), the premise of this particular piece of advice was along the lines of Obi...

Internet usage is evolving, and so are the application scenarios for business technology. In the foreseeable future, desktop personal computers will produce a much smaller share of commercial internet protocol (IP) traffic. Mobile and portable devices -- other than PCs -- will drive th...
It was a long and full day for me at Devops Summit. I could fill a week or more with blogs on ideas I both agreed - and of course, disagreed - with from sessions and panels. But for now, here's a digestible selection. Ephemeral Infrastructure From John Willis (@botchagalupe) sessi...

In December 2012, research firm Coleman Parkes released a landmark study about the business benefits of service virtualization. The findings were significant: 60% of the respondents indicated that unavailability of systems for testing routinely caused software projects to be delivered ...

There are two fairly recurrent memes in IT infrastructure: the There’s an API for that! theme, and the Out of box! theme. It is actually telling that both continue to get play in IT given that they represent polar opposites. Assuming that each has a value, when do you need something th...
Are you thinking of moving some business operations to the cloud? Moving your business to the cloud is probably an idea that would set you on course for better profitability. However, this transition is far less easy than simply choosing a cloud vendor and moving a portion of your busi...
