Groovy is a elegant, dynamic, agile, OO language. I like to program in Groovy because it is fun and the code is concise and highly expressive. Writing code in a language is hardly about using its syntax, however. It is about using the right idioms. Come to this section to pick up some nice Groovy idioms.
In this presentation you will take some Java code that does common operations and transform it to idiomatic Groovy. You will participate in exploring various options as you help transform several examples. Each example is intended to hone a particular idiom or Groovy facility.
Prerequisite: Some knowledge of Groovy is helpful but not required.
Groovy is concise and expressive. However, writing good quality code takes effort and discipline.
Come to this session to learn about good coding styles, ways to observe, and measure the quality of your Groovy code. We will take several Groovy code examples, identify smells in them, measure and refactor to improve the quality.
Functional programming style is gaining popularity. Though Groovy is not a functional programming language, writing in functional style is common and idiomatic in Groovy. While you have used these features in Groovy, learning the tents of functional programming will help you recognized these and make better use of them in the future.
In this presentation we will learn what functional programming is and its benefits. Then we will explore the functional style of programming in Groovy.
The concise, expressive syntax of Groovy and the ability to create internal DSLs make Groovy a great language for testing related tools. I
In this presentation you will learn different Groovy based testing related tools that can help you attain and sustain agility on your projects. Rather than looking at a mere laundry list of tools, we will explore the key benefits and rationale for each tool, and understand strengths and weaknesses.
The increasing popularity and availability of multicore processors is creating a whole new set of challenges--although you can enjoy true concurrency, you're now faced with higher contention and synchronization issues. Deploying an existing application on a multicore processor may bring out previously hidden concurrency issues. Java's multi-threading facility by itself isn't enough---it's a very low level abstraction. Instead, you need a paradigm that provides a higher level of abstraction to deal with concurrency. It's time to embrace Functional Programming.
Scala is a hybrid Object-Oriented/Functional Programming language on the JVM. Using Scala, you can create traditional imperative programs, intermix them with Java code, and at the same time take advantage of higher levels of abstraction. You can use features that lead to concise, highly expressive code that remove the pain of dealing with concurrency.
Programming Scala will show you the fundamentals of functional programming using Scala. Very quickly, you'll learn how this statically typed language can give you dynamic capabilities to create concise, scalable, highly capable concurrent code.
Pragmatic programmers always use the right tool for the job. For concurrent programming on the Java VM, Scala is the tool, and Programming Scala by award-winning author Venkat Subramaniam is your guide.
The strength of Java is no longer in the language itself; it's in the Java Platform (the JVM, JDK, and rich frameworks and libraries). But recently, the industry has turned to dynamic languages for increased productivity and speed to market.
Groovy is one of a new breed of dynamic languages that run on the Java platform. You can use these new languages on the JVM and intermix them with your existing Java code. You can leverage your Java investments while benefiting from advanced features including true Closures, Meta Programming, the ability to create internal DSLs, and a higher level of abstraction.
If you're an experienced Java developer, Programming Groovy will help you learn the necessary fundamentals of programming in Groovy. You'll see how to use Groovy to do advanced programming including using Meta Programming, Builders, Unit Testing with Mock objects, processing XML, working with Databases and creating your own Domain-Specific Languages (DSLs).
Want to be a better developer? This books collects the personal habits, ideas, and approaches of successful agile software developers and presents them in a series of short, easy-to-digest tips. This isn't academic fluff; follow these ideas and you'll show yourself, your teammates, and your managers real results. These are the proven and effective agile practices that will make you a better developer.
This book will help you improve five areas of your career:
These practices provide guidelines that will help you succeed in delivering and meeting your user's expectations, even if the domain is unfamiliar. You'll be able to keep normal project pressure from turning into disastrous stress while writing code, and see how to effectively coordinate mentors, team leads, and developers in harmony.
You can learn all this stuff the hard way, but this book can save you time and pain. Read it, and you'll be a better developer.
Like most complex tasks, .NET programming is fraught with potential costly, and time-consuming hazards. The millions of Microsoft developers worldwide who create applications for the .NET platform can attest to that. Thankfully there's now a book that shows you how to avoid such costly and time-consuming mistakes. It's called .NET Gotchas.
The ultimate guide for efficient, pain-free coding, .NET Gotchas from O'Reilly contains 75 common .NET programming pitfalls--and advice on how to work around them. It will help you steer away from those mistakes that cause application performance problems, or so taint code that it just doesn't work right.
The book is organized into nine chapters, each focusing on those features and constructs of the .NET platform that consistently baffle developers. Within each chapter are several "gotchas," with detailed examples, discussions, and guidelines for avoiding them. No doubt about it, when applied, these concise presentations of best practices will help you lead a more productive, stress-free existence.
What's more, because code examples are written in both VB.NET and C#, .NET Gotchas is of interest to more than 75 percent of the growing numbers of .NET programmers. So if you're a .NET developer who's mired in the trenches and yearning for a better way, this book is most definitely for you.
