Message-Oriented Middleware

Aggregated on: Wed May 25 2022 16:35:59 GMT+0000 (Coordinated Universal Time)

What Is Message-Oriented Middleware? Message-oriented middleware is a group of software products and applications that allows applications to communicate and exchange data or messages between distributed systems. Message-oriented middleware entails data passage between applications that use a communication channel carrying self-contained elements of messages. A message-oriented middleware system offers asynchronous communication and sends data to perform asynchronous operations. This system employs inter-application software that depends on asynchronous message passage that opposes request-response architecture. The platform comprises a message queue used as a temporary stage, rendering the destination program busy or unconnected. This mechanism helps to store the message on the message-oriented middleware. Clients using message-oriented middleware can send and receive messages through this queue. The queues are the main component of implementing asynchronous interactions in message-oriented middleware.

How to Monitor for Data and Concept Drift

Aggregated on: Tue May 24 2022 22:06:00 GMT+0000 (Coordinated Universal Time)

Data Drift Data and concept drift are frequently mentioned in ML monitoring, but what exactly are they, and how are they detected? Furthermore, given the common misconceptions, are data and concept drift things to be avoided at all costs or natural and acceptable consequences of training models in production? Read on to find out. What Is It? Perhaps the more common of the two is data drift, which refers to any change in the data distribution after training the model. In other words, data drift commonly occurs when the inputs a model is presented within production fail to correspond with the distribution it was provided during training. This typically presents itself as a change in the feature distribution, i.e., specific values for a given feature may become more common in production. In contrast, other values may see a decrease in prevalence. For example, consider an e-commerce company serving an LTV prediction model to optimize marketing efforts. A reasonable feature for such a model would be a customer’s age. However, suppose this same company changed its marketing strategy, perhaps by initiating a new campaign targeted at a specific age group. In this scenario, the distribution of ages being fed to the model would likely change, causing a distribution shift in the age feature and perhaps a degradation in the model’s predictive capacity. This would be considered data drift.

Leveraging AI and Machine Learning Technology For Medical Imaging

Aggregated on: Tue May 24 2022 21:35:59 GMT+0000 (Coordinated Universal Time)

Breast cancer has been prevalent among females for some decades. However, it is the most pernicious cause of mortality among women worldwide — the data released by premier medical research organizations states so. “In 2020, there were 2.3 million women diagnosed with breast cancer and 685 000 deaths globally. As of 2020, 7.8 million women alive have been diagnosed with breast cancer in the past 5 years, making it the world’s most prevalent cancer,” the World Health Organisation (WHO) points out in its recent report on breast cancer. Early diagnosis is the only lifeguard — and employing machine learning in medical imaging can precede the path to wellness and reduced mortality rate. Since early detection of breast cancer is the only way to restore well-being, medical technology advancements can be brought well to the rescue. Integrating deep learning in medical image analysis has proven to be a game-changer in overpowering the diagnostic challenges cropping up during cancer treatment. Medical imaging technology that has been explicitly developed for detecting breast cancer symptoms at an earlier stage provides significant aid for the timely and accurate screening of breast cancer in women.

In a previous article, I covered all the different lifecycle hooks in Vue. One of the things that most people get confused about when talking about lifecycle hooks, is the difference between created and mounted. They both have similar names, and they feel like they should do the same thing, but there are some subtle differences. The Difference between Created and Mounted in Vue To begin with, both created() and mounted() have access to the data and props on your prototype. For example, both hooks will console log 'My Message' below, as well as the default value for myProp, which is 'Some Prop':

What is Code Refactoring and Why Should You Do It?

Aggregated on: Tue May 24 2022 18:20:59 GMT+0000 (Coordinated Universal Time)

Sometimes code can go bad faster than guacamole left on the table after a couple of hours. Code refactoring is cleaning up and revamping the underlying code behind the curtain, so it runs cleaner without changing how it functions for end-users. Everything on earth tends to decay after a certain amount of time. Bananas turn to mush. Bread turns moldy. Guacamole turns brown. At least you can make bread out of those mushy bananas, but even that can also go bad after a certain amount of time. Software code can also turn and start to "smell" musty after a while. The term "code smell" is an actual thing. Old, long-winded, unnecessarily-repetitive lines of code can start to malfunction, decay, and cause problems. And because of the increasing complexity of interactions between various lines of code in different apps, this process of code decay can happen quickly. This is why regular software updates to improve and streamline code are essential. And that is just where code refactoring comes in.

Functional vs. Non-Functional Requirements: The Full Guide, Definitions, and Technical Examples

Aggregated on: Tue May 24 2022 16:50:59 GMT+0000 (Coordinated Universal Time)

What Are Functional Requirements? Functional requirements specify which functions your system (or system component) must have. In other words, they define what your custom software needs to do. If these requirements are not met, the software fails; it’s non-negotiable. Examples of the most common functional requirements are (1) use cases and (2) document descriptions. Use Case Use cases can be numbered lists with text or diagrams that describe user actions. Each use case illustrates behavioral scenarios through one or more functional requirements. First, a set of use cases is selected — and then an analyst can derive the functional requirements that need to be implemented in order for each use case to be fulfilled. For example, a navigational use-case model for a conference management system is proposed in the diagram below. Each main functionality is associated with user roles: Here’s an example of a use case numbered list for a subway ticket machine:

Choose Your Player: Cloud-Based High Availability Options for IBM i Applications

Aggregated on: Tue May 24 2022 16:50:59 GMT+0000 (Coordinated Universal Time)

If an enterprise has been in business longer than five years, it’s safe to say it has legacy business applications such as ERP systems running on IBM i or AIX, along with high availability (HA) software to protect those applications against unexpected outages. The mature HA options for IBM i on-premises can make IT teams reluctant to migrate those legacy business applications to the cloud. As these applications are typically extremely customized, not to mention vital to the business, IT teams must guarantee they are available to users all day, every day. Luckily, IT has more options here than they may realize. There are solutions that allow IT to have both, running IBM i workloads in the public cloud (while enjoying all the advantages that entails) without losing those strong HA offerings.

Customer satisfaction is everything for each business since it directly influences the profit of organizations. The feedback affects each industry differently, depending on various criteria. For the transportation services, the reasons for users to keep utilizing the application might involve both standard requirements, like the user-friendly interface or full-fledged functionality, and something more specific, such as the clear dashboard with statistical data about deliveries, the possibility to track parcels in real-time, or accurate estimated time of arrival. In the current world, people get used to monitoring by themselves all the services they order. Perhaps, it is because nothing is hidden with 'online' reality anymore. And all the businesses which provide any service, either for other businesses or customers, should deliver maximum information about the product and order status. This can be easily achieved with different types of tools and technologies. Because in this article, we focus on the estimated time of arrival within transportation services and how to enhance ETA, we will define the significant aspects for you. So, as a result, your logistics company will be able to satisfy users and attract more profit to your logistics software. Indeed, in the modern world, correspondence with innovational technologies is also one of the main criteria for users. And logistics market is booming with such novelties. Calculating ETA accurately is one of them. Furthermore, according to the Bizrate survey, when consumers receive items on time, 43% have favorable reviews regarding delivery services. Meanwhile, 65% consider projected delivery time a critical factor in selecting a logistics company. Hence, when users ask for it and relate such functionality with upstanding organizations, you need to give them that. So, we will elaborate on such questions: what ETA consists of, how to calculate it, how to enhance it, and which factors need to be optimized for better ETA functionality. Well, let's start from the beginning.

How to Design a CRUD Web Service for Inheritable Entity

Introduction Sometimes we need to develop a web service that provides CRUD (Create, Read, Update, and Delete) operations for an entity that supports inheritance. However, the traditional layered architecture (controller layer, service layer, and repository layer) is not enough to have a clean and scalable code. Indeed, if we put the business logic and mapping code inside the service layer, we will have two main problems: Having multiple conditions based on the DTO class type Each time we want to introduce a new subclass, we need to modify the service layer, which is not good if we are developing a framework. The code below illustrates what the service class will look like if we use the traditional architecture:

Comprehensive Guide to Jenkins Declarative Pipeline [With Examples]

Aggregated on: Mon May 23 2022 16:35:59 GMT+0000 (Coordinated Universal Time)

Jenkins Pipeline is an automation solution that lets you create simple or complex (template) pipelines via the DSL used in each pipeline. Jenkins provides two ways of developing a pipeline — scripted and declarative. Traditionally, Jenkins jobs were created using Jenkins UI called freestyle jobs. In Jenkins 2.0, Jenkins introduced a new way to create jobs using the technique called pipeline as code. In the pipeline as code technique, jobs are created using a script file that contains the steps to be executed by the job. In Jenkins, that scripted file is called a Jenkinsfile. In this Jenkins tutorial, we will take a deep dive into Jenkins Declarative Pipeline with the help of Jenkins Declarative Pipeline examples. Let’s get started with the basics.

There are many convolutional neural network (CNN) architectures. Those architectures differ in how the layers are structured, the elements used in each layer, and how they are designed. This affects the speed and the accuracy of the model which will help to perform various tasks. The following are some of the common CNN architectures. The word "common" is referring to pre-trained weights which are fine-tuned by deep learning libraries such as Keras, TensorFlow, Fastai, and so on (Karim, 2019).

The NonNullable type is a utility type in TypeScript that creates a new type, whilst removing all null or undefined elements. It lets us take existing types, and modify them so they are more suitable in certain situations. Let's look at how it works. Custom Types This article covers custom types. To learn more about custom types, read my guide about it here.

How We Migrated Hundreds of Posts from Hugo to Webflow

Aggregated on: Sun May 22 2022 19:05:58 GMT+0000 (Coordinated Universal Time)

We have recently completed the migration of Nebula Graph’s website from Hugo to Webflow, moving from a static website to a more interactive one. There were a number of reasons for this decision, but most notably it was the performance and the ability to do things like form submission and no-code design. While the redesign of the website on Webflow was easy, since we have an amazing in-house design team and Webflow is also very friendly to designers, the difficult part is migrating more than 100 blog posts we already published from Hugo to Webflow’s Content Management System (CMS).

Troubleshooting Memory Leaks With Heap Profilers

Aggregated on: Sun May 22 2022 18:35:57 GMT+0000 (Coordinated Universal Time)

After a system runs for a long time, the available memory may decrease, and some services may fail. This is a typical memory leak issue that is usually difficult to predict and identify. Heap profilers are useful tools to solve such problems. They keep track of memory allocations and help you figure out what is in the program heap and locate memory leaks. This article introduces how to use heap profilers, and how widely-used heap profilers, such as Go heap profiler, gperftools, jemalloc and Bytehound, are designed and implemented. I hope this article can help you better understand and use heap profilers for your own projects.

The End of the Beginning for Apache Cassandra

Aggregated on: Sun May 22 2022 18:05:58 GMT+0000 (Coordinated Universal Time)

Editor’s note: This story originally ran on July 27, 2021, the day that Apache Cassandra 4.0 was released. Today is a big day for those of us in the Apache Cassandra community. After a long uphill climb, Apache Cassandra 4.0 has finally shipped. I say finally because it has at times seemed like an elusive goal. I’ve been involved in the Cassandra project for almost 10 years now and I have seen a lot of ups and downs. So I feel this day marks an important milestone that isn’t just a version number. This is an important milestone in the lifecycle of a database project that has come into its own as an important database used around the world. The 4.0 release is not only incredibly stable in the history of Cassandra, but it’s also quite possibly the most stable release of any database. Now it’s ready to launch into the next 10 years of cloud-native data; it has the computer science and hard-won history to make a huge impact. Today’s milestone is the end of the beginning.

These articles will guide the reader step by step to explore the most important features introduced starting from version 9. The aim is to make the reader aware of how important it is to move forward from Java 8, explaining the enormous advantages that the latest versions of the language offer.

How BDD Works Well With EDA

Aggregated on: Sun May 22 2022 16:35:57 GMT+0000 (Coordinated Universal Time)

Behaviour-Driven Development (BDD) and Event-Driven Architecture (EDA) work well together as they complement each other’s strengths and weaknesses. Using both can result in a shorter time to market for new functionality and a more maintainable system. Behaviour-Driven Development encourages a common language between users and developers in describing requirements in a form the users can understand but can also automatically be checked as the application is developed and maintained. BDD increases the inclusion of users, focuses on requirements capture and maintains the velocity of development as the application increases in complexity.

A COO's Guide to Test Strategy Creation

Aggregated on: Sun May 22 2022 16:35:57 GMT+0000 (Coordinated Universal Time)

A test strategy is a set of high-level definitions that determine how software testing processes are going to be performed, driving our decisions on how to invest our testing efforts. Creating a well-thought test strategy is crucial to understanding the overall scope of your project, and what testing approaches, tools and skills are required in order to develop a successful product that provides a great user experience. However, creating a test strategy is a complex task. Every piece of software is unique, and as such, objectives, user expectations, budgets and timelines differ greatly between projects. In this webinar recording and in this article, I'll share the foundational bases for creating and revising successful test strategies that you can adapt to your software projects regardless of their specific requirements.
