There are a lot of misconceptions in the software development world. Today we are going to address this one: “Java 8, for example, introduced the Optional class. It’s a container that may hold a value of some type, or nothing. In other words, it’s a special case of a Monad, known in Haskell as the Maybe Monad. You can now …
Composition is one of the fundamental concepts in object-oriented programming. It describes a class that references one or more objects of other classes in instance variables. This allows you to model a has-a association between objects. You can find such relationships quite regularly in the real world. A car, for example, has an engine and modern coffee machines often have …
One of the main reasons for using .NET Core is that you can run it on multiple platforms and architectures. So you can build an app that will run on Windows, but also on Linux, macOS and on different architectures like x86 and ARM. This is perfect for lots of scenarios, including desktop applications. You can learn about other reasons …

When I think of .NET, I think of the .NET Framework and Visual Studio. The first production version 1.0 of the .NET Framework was released on February 13 in 2002. In technology years, this is light-years ago. Since then, new versions of the .NET Framework have been released and Microsoft has started efforts to keep .NET a viable development platform …
Due to the complexity of current day web applications, ALM, or Application Lifecycle Management, is important now more than ever. It’s no longer just the coding and development stage that is crucial to an application’s success. It’s the initial Requirements (or Governance) stage, where teams decide what and how the application will be created and what problem it will seek …
Stackify CEO Matt Watson said the #1 problem with agile development is lack of confidence in deployment. Rapid deployment, one of agile’s greatest strengths, can also be a major weakness if testing and automation are not properly developed. Moving too fast without the right processes in place can lead to errors, downtime, and poor user experience. However, companies can gain …
1. Introduction In this article, we’ll discuss a number of approaches that can be helpful for improving the performance of a Java application. We’ll start with how to define measurable performance goals and then look at different tools to measure, monitor application performance and identify bottlenecks. We’ll also look at some of the common Java code level optimizations as well …
Amongst the tribe of infinite learners, self-taught programmers, and digital nomads, there are few tools better than YouTube. What started as a simple video-sharing site is now arguably the second largest search engine in the world, rich with educational resources that puts the Library of Alexandria to shame. In fact, Google says, “more than 7 in 10 viewers use the …
Speed is the name of the game in today’s software-driven world. The best companies deploy software updates daily, sometimes more. In order to reach such epic levels of productivity, businesses need a plan for managing their software from beginning to end. That’s where application lifecycle management (ALM) comes in. ALM helps businesses make smart decisions about their software and manage …
The word polymorphism is used in various contexts and describes situations in which something occurs in several different forms. In computer science, it describes the concept that objects of different types can be accessed through the same interface. Each type can provide its own, independent implementation of this interface. It is one of the core concepts of object-oriented programming (OOP). …
There is a big trend in software development for developers to be more involved in the deployment, monitoring, and overall operations of web applications.

Inheritance is one of the core concepts of object-oriented programming (OOP) languages. It is a mechanism where you can to derive a class from another class for a hierarchy of classes that share a set of attributes and methods.

Software developers spend a lot of time chasing bugs and putting out production fires. I’ve been a software developer for over 15 years and it has always just been part of the job. Thanks to agile development, we are constantly shipping new code. By-products of constant change are constant issues with performance, software defects, and other issues that eat up …
Over the past few years, I’ve become more and more convinced that having really good production logs is critical to running a successful software deployment. Logging has always been important, however if you’re deploying a web of microservices and a business transaction might span twenty different services, then searchable centralized logging is crucial. There are plenty of great tools available …
