It takes a week to travel the 8,000 miles overland from Java to Kotlin. If you're an experienced Java developer who has tried the Kotlin language, you were probably productive in about the same time. You'll have found that they do things differently in Kotlin, though. Nullability is important, collections are different, and classes are final by default. Kotlin is more functional, but what does that mean, and how should it change the way that you program? And what about all that Java code that you still have to support? Your tour guides Duncan and Nat first made the trip in 2015, and they've since helped many teams and individuals follow in their footsteps. Travel with them as they break the route down into legs like Optional to Nullable, Beans to Values, and Open to Sealed Classes. Each explains a key concept and then shows how to refactor production Java to idiomatic Kotlin, gradually and safely, while maintaining interoperability. The resulting code is simpler, more expressive, and easier to change. By the end of the journey, you'll be confident in refactoring Java to Kotlin, writing Kotlin from scratch, and managing a mixed language codebase as it evolves over time.

This book concerns software design. Although many current discussions of scientific programming focus on scalable performance, this book focuses on scalable design. The authors analyze how the structure of a package determines its developmental complexity according to such measures as bug search times and documentation information content. The work presents arguments for why these issues impact solution cost and time more than does scalable performance. The final chapter explores the question of scalable execution and shows how scalable design relates to scalable execution. The book's focus is on program organization, which has received considerable attention in the broader software engineering community, where graphical description standards for modeling software structure and behavior have been developed by computer scientists. These discussions might be enriched by engineers who write scientific codes. This book aims to bring such scientific programmers into discussion with computer scientists. The authors do so by introducing object-oriented software design patterns in the context of scientific simulation.

The C++ programming language allows programmer to make all kinds of mistakes such as access memory beyond the bounds of an allocated array, or read memory which was never initialized, or allocate memory and forget to de-allocate it, e.g. there are great many ways to "shoot yourself in a foot" while programming in C++, and the C++ language will not catch you by the hand and instead will proceed happily until it will either crash or produce an unreasonable result or do something which is in computer literature called by a vague but scary term "an unpredictable behavior". So, in this sense, the C++ is unsafe. This book contains discussion of some of the most typical mistakes made by us, programmers, in C++ code and also some recipes how to avoid each of these mistakes. The undeniable truth is that any program significantly more complex than "Hello, World" would contain some number of errors, also affectionately called "bugs", which are put in there by the Programmer. The Great Question of Programming is how do we make the number of these bugs smaller (that is, without slowing the process of programming to a halt)?
