Iterate/Aggregate Fault Handling in WSO2 EI Posted: 19 Feb 2020 02:13 PM PST In WSO2, we can implement the Splitter and Aggregator EIP using the Iterate and Aggregate mediators. With the Splitter pattern, we can split a message composed by different elements that need to be processed individually, and then we use the Aggregator pattern to aggregate the results of each individual call and then perform some processing over the aggregated results. Happy Path Example In a happy path example, all the requests and processing done inside the iterate mediator will occur with no failures, and the aggregate mediator will handle the results of all the requests made. We can see that in the proxy below:

Handling Flutter Webview Back-Button Posted: 19 Feb 2020 11:08 AM PST In my previous article, I introduced how to implement Flutter Webview URL Listeners to your flutter applications. Now, we need to add functionality to navigate through the website with the back button. Currently, instead of going back, our application gets closed. To prevent this, we need to add an operation check to see whether the webview can go back, and if it can, then, we need to load the webview of previous pages.

Data Binding and Server-Side Rendering in Angular and React Posted: 19 Feb 2020 10:47 AM PST Today, almost all modern web applications are built with frontend frameworks or libraries like Angularjs and React. Presently, these both frameworks are trending because of their superheroic capabilities, and significant aspects, such as Data Binding and Server Rendering.  Let's see these both aspects in detail in Angularjs and Reactjs.

Incorporating Fault-Tolerance Into Your Microservice Architecture Posted: 19 Feb 2020 10:05 AM PST Fault-tolerance is an essential trait of every microservice architecture. The reasons behind this are plain and simple: After integration points in our system reach a certain number, failures are going to happen daily. The reasons are simply statistical. As I will show, we can't defy the laws of mathematics. That's why we need to understand the key drivers of failures from a higher perspective. It's required to make strategic decisions effectively. Without these decisions, it's impossible to achieve the level of fault-tolerance we aim for.

Java PrintWriter With Example Posted: 19 Feb 2020 09:04 AM PST In this article, we will look at one of the important classes of Java version 7, PrintWriter. Let's get started. Introduction The PrintWriter class in Java was released in Java 7, as a subclass of the Writer class. This class is basically used for printing the formatted representations of objects to a text-output stream.

Integrating With SaaS Applications - Common Architectural Elements Posted: 19 Feb 2020 08:19 AM PST The introduction to integrating with SaaS applications laid the groundwork for a deeper exploration of its logical diagram. In this article, we continue with a look at the common architectural elements. A description is provided to guide you with aligning what we've presented here with the landscape your organization works with every day. These details should help you understand both what the elements contain and how they might align and how their functionalities are grouped. Let's look at the foundation of our integrate with SaaS applications blueprint, the logical diagram with it's architectural elements.

Java Thread Synchronization and Concurrency Part 1 Posted: 19 Feb 2020 08:12 AM PST Introduction Java thread synchronization and concurrency are the most discussed topics during various design phases of a complex application. There are many aspects of threads, synchronization techniques to achieve great concurrency in an application. The evolution of CPUs over the years (multi-core processors, registers, cache memory, and the main memory (RAM) has lead to some areas that usually developers tend to overlook — like thread context, context-switching, variable visibility, JVM memory model vs CPU memory model.  In this series, we will discuss various aspects of the Java memory model, including how it impacts thread contexts, synchronization techniques in Java to achieve concurrency, race conditions, etc. In this article, we'll focus on the concepts of threads, synchronization techniques, and the memory models of both Java and our CPU.

Understanding Architecture Models of Chatbot and Response Generation Mechanisms Posted: 19 Feb 2020 08:07 AM PST This is the generation of chatbots and artificial intelligence. The recent advancements in this arena are sprouting to the extent that chatbots are replacing humans in customer service. Artificial intelligence has grown to become something more than a mere science fiction dream. Did you ever think that humans would be interacting and communicating with intelligent machines? Chatbots have made this unrealistic thought possible with its intelligence, human-like replies, and ability to learn with experience through machine learning. Chatbots are one of the most popular, widely adopted, and accessible ways to utilize AI in real life. Businesses are looking at chatbots as an important tool for automating customer service and business processes.

The Best JavaScript Testing Tools for Your React Project Posted: 19 Feb 2020 08:06 AM PST Trust, but verify. A Russian phrase made popular by president Reagan fits perfectly when we are talking about testing or QA. Everyone trusts themselves, every programmer or a developer has trust in code. And why shouldn't they?  But, we know how it goes. In the programming world, even a miniscule mistake could cost a lot. And that is why we have testing.

The Five Biggest Security Threats and Challenges for IoT Posted: 19 Feb 2020 08:05 AM PST In the coming decade, the biggest threat to us will not be wars between countries or states. The biggest threat that we should be most concerned about is the cyber war. It is a direct threat to our privacy, our private conversations, moments, pictures — everything that encompasses our life. Technology has always been a double-edged sword. With all the benefits and advantages, follows unknown and unprecedented threats. For us to succeed and work in harmony with technology, we need to address and confront the potential threats that it brings. Simply ignoring or putting them aside is not a solution.

AI Trends Responsible for the Rapid Shape-Shifting of the Future Posted: 19 Feb 2020 08:03 AM PST Rapid shape-shifting of the future. What does the future hold for us? Or more precisely, how will the future unfold? One thing that we know unanimously is that the digital revolution is here. This revolution is cascading across every industry and organization, resulting in wide-scale enterprise disruption with redefined customer expectations.

Implementing and Deploying the Domain Project With MuleSoft Posted: 19 Feb 2020 06:55 AM PST Introduction Domain Project is used to create shared resources that can be reused. Mule can define selected connectors as common resources and expose them to all apps deployed under the same domain. These resources are known as shared resources. To host them, you must create a Mule Domain Project and then reference it from each of the projects that use the elements in it. Once defined, any Mule app associated with a particular domain can access resources in this file. Note that Mule apps can be associated with only one domain at a time.
