A new language feature in Java 16, called Pattern Matching for instanceof, uses a type pattern instead of just a type for the instanceof operator. The benefit of this feature is that you can avoid unnecessary code that usually has to be used for casting the target object to the type and declaring a new variable for the resulting object.
The article discusses how the new switch statement is simplified and how the new switch expression simplifies. After setting the environment, we’ll discuss what was lacking in the switch statement that makes it less agile. Then, we’ll discuss how Java 14 simplifies switch.
In Scrum, the product owner and the ScrumMaster are supposed to drive sustainable development. But there's a third force missing from the formula: the health of the code itself. We often forget that our code is also a member of our team, and we have to be concerned about its health and well-being as much as any other team member. That means using practices to develop good code from the beginning.
The majority of managers are promoted due to their software development expertise. But becoming a successful manager requires a drastic change of focus. There is a set of expectations to consider before making that leap to the “dark side.”
You may not have heard about gamification, but instructional designers are now using game principles to help with retention of learned material in many forms of training. Ross Smith and Rajini Padmanaban believe that developers' UX and app design can benefit from gamification.
Most software needs to be "maintainable" and have high "internal quality." But what does that mean in practical terms? Code smells form a vocabulary for discussing code quality and how well suited code might be to change. The smells also provide good indications as to what to refactor and how.
Mistakes happen. It's how you respond to them that matters. Teams might react to a bug with panic and blame, leading to a quickly hacked fix and possibly more issues. Taking time to investigate and learn leverages problems into process and practice improvement and a higher quality product.

Pair programming: the practice you love to hate! Twenty years after being introduced as part of Extreme Programming, the collaborative practice is still a thing. And if you thought pairing was nuts, now there's mobbing, where the entire team works together on one thing at a time. Yet we often hear teams say, "We go faster because we are mobbing." In this anecdote-heavy session, you'll hear Jeff Langr's history of working through various models for collaboration (or not) across the past several decades, including solo programming, pairing, and mobbing. He'll show you his office blueprints to help put you in his shoes and understand what contributed to the ups and downs of each model. You'll learn tips for success, pitfalls to watch out for, and Jeff's take on why mobbing or pairing might help us go faster. Come with a willingness to lose your preconceptions.
Pair programming is the practice you love to hate! It's been nearly twenty years since Extreme Programming promoted pair programming as a collaborative practice, and it's still here.

Do you have trouble generating test case ideas? Are there seemingly obvious bugs getting through your test plan? Are you considering revamping your current test analysis and design? If you answered yes to any of these questions, then this session is for you. You may have heard of mob...
To keep your iOS app running butter-smooth at 60 frames per second, Apple recommends doing as many tasks as possible asynchronously or “off the main thread.” Joe Keeley introduces you to some basic concepts of asynchronous programming in iOS. He discusses what threads and queues are, how...
