When it comes to microservices there are myths and uncertainty about the journey ahead. Deploying a “Hello World” app on Docker is a long way from making microservices work in real enterprises with large applications, complex environments and existing organizational structures. Februar...
Nike is an organization that understands the shift described by Michael Porter, to a third generation of competitive advantage where technology becomes an integral part of product value. Fitness is a key area where IoT wearable technologies combined with new apps will become differenti...
Many of the well-known examples of DevOps success we read in blogs on the Internet paint an idyllic picture of DevOps productivity. A team was facing a stodgy, slow-moving operations department, teams weren’t delivering software on time. Those teams moved to DevOps, became proactive ab...
This morning I got the following email from a Java developer: “It seems you are doing less Java and more web development every year.” This got me thinking, and I decided to write this blog. Am I still a Java developer after 17 years of using this language? I certainly am. But in today...
I recently had the opportunity to attend UI19 in Boston, a long-running conference focused on user experience design and ways to be more effective in a UX role as part of a larger team. One of the presentations in particular stuck with me as I returned to Boulder thinking about VictorO...
The NetBeans New File wizards greatly simplify writing boilerplate code. One specific instance is the creation of JPA Controller Classes from an Entity Classes. The class file, or files, written for you will contain all the basic methods of JPA for CRUD operations on the entity or enti...

Whether you are a release manager, a release engineer, or a someone just supporting a release you understand that the intersection of software releases and instant messaging can be frustrating. Whether you use Skype, Jabber, Slack, or any other group-based instant messaging applicatio...
Kafka has become the de-facto standard for handling real-time streams in high-volume, data-intensive applications, and there are certainly a lot of those out there. We thought it would be valuable to conduct a quick poll to find out which which implementation of Kafka Producers and Co...
Traditionally if a critical customer has an issue in the middle of your night, it wouldn’t be answered until the next business day. With the Desk.com and PagerDuty integration, your team can immediately get notified about top-tier support issues as they happen, and can then handle the ...

Finished writing the WebSocket chapter for the second edition of my Java 24 Hour Trainer. In this blog I’ll show you one of the code samples from lesson 28. Pretty often you need to write a program that publishes the same message to all connected clients. For example, multiple cl...
The JVM issues vary from Java OutOfMemory Error to JVM Crash. Application developers might be not completely equipped to determine the root cause of the issue, hence DevOps can play a vital role in narrowing down the issue and connecting the right people/team to rectify the problem. ...
Most forward-looking CEOs have already made their move to prepare for the future that they foresee – where business technology is a key deciding factor for them to attain ongoing commercial prosperity. This new digital-propelled environment will profoundly change business processes, al...
It's generally a good practice to minify and combine your assets (JS & CSS) when deploying to production. This process reduces the size of your assets and dramatically improves your website's load time. Source maps create a map from these compressed asset files back to the source file...
It seems like the fast-paced world of mobile technology would make it difficult to “stop and look around once in a while” but several recent milestones are worthy of our attention. The growth of the mobile application industry over the last 36 months has been startling to say the least...

The Internet of Things: Another Silicon Valley invention to get all excited about? Or is it something that will hold up beyond the California border and next January? If you’re aching to know, then I suggest you attend the upcoming “Monetizing the ‘Internet of Things’” presentation ...

Applications are as integral to F5 technologies as they are to your business.

An old adage holds that an individual can be judged by the company he keeps. If that holds true for organizations, t...

I hear this question fairly regularly and would like to walk you through how to host the controller in your own Azure cloud. First off, the pros of having AppDynamics with Azure: Have full control and ownership of the data collected by AppDynamics Provide additional security to acc...
If the existing system does fifteen things, write down the major tasks of that system and divide them into as many verticals as necessary to describe the broad functional areas that require attention. If the replacement is intended to be a custom-developed, on-premises system, it’s per...
More and more Web sites and applications are being moved from Apache to nginx. While Apache is still the number one HTTP server with more than 60% on active Web sites, nginx has now taken over the 2nd place in the ranking and relegated Microsoft’s IIS to 3rd place. Among the top 10.000...
You are on top of your game. You have a log analysis tool churning logs from all your applications and infrastructure. And now that you have data (LOTS and lots of data…), you are able to understand your infrastructure better than you ever did before. You might even build a dashboard o...
Probably the most popular question during Java technical interviews is “What’s the difference between abstract classes and interfaces”. In my own three year old book I’ve offered the following answer: “An abstract class may contain code in method bodies, which is not allowed in an in...
It doesn't matter if your title puts you in Ops, Dev, or DevOps, being able to track down the big insights from your data is the secret-sauce every engineer is looking for. Collecting the data is a step in the right direction, but organizing, tagging, monitoring, and reporting from the...
Logs have been around for a while, not quite as long as the wheel, but not far off. Here at Logentries, we have the mantra of evolve don’t revolve (as in don’t sit around spinning your wheels getting nowhere). We are taking this concept and looking to evolve the way you work with and ...
We’ll discuss configuring Apache and Nginx both to send JSON formatted logs and how to take advantage of the search functions, sharable dashboards, and reporting capabilities within the Logentries platform. I'm often asked on calls with our customers what is the preferred format for l...
Some time ago I blogged that Java Swing should be deprecated and replaced with JavaFX. In this blog I’ll show a piece of JavaFX namely event handlers and binding. I’ve created a simple Sign In window with a GridPane layout (it’s JavaFX equivalent of Swing’s GridBagLayout). I’m not goin...
One of the most powerful features of QuickBase is the ability to share data across applications within a QuickBase account. Many QuickBase application managers may be unaware of these features or may be unaware of how to best gain benefits and avoid some important associated risks, suc...
Logentries new Aggregated Live Tail provides effortless, real-time visibility that you cannot get anywhere else…and is a joy to use (and I cant say the same about carrying a cat by its tail – for so many reasons). For those of you not familiar with our existing Live Tail view, Aggrega...
In Part V, we discussed processing delays caused by “slow” client and server nodes. In Part VI, we’ll discuss the Nagle algorithm, a behavior that can have a devastating impact on performance and, in many ways, appear to be a processing delay. Beyond being important for (reasonably) a...
While working on the second edition for my Java 24-hour Trainer book I’m re-writing some of the code samples to use lambda expressions. Today I was re-writing an example for wait/notify for the chapter on multi-threading. Beside illustrating the wait/notify, I used a closure in this ex...
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...
