Book Description
Memory management. One of the most basic parts of software development, often kept on the side even though it has the most profound effect on how we write our code. Delphi provides a variety of types with their own memory management logic, as well as two sets of compilers that provide different memory management systems for classes. * Classic Delphi compiler currently supported on Windows and OSX platforms - using manual memory management while providing ARC for certain types. * Next generation ARC Delphi compiler supported on mobile Android and iOS platforms, as well as Linux - using full ARC - Automatic Reference Counting memory management system. Each memory management system has its good and bad sides. Each offers solutions to some problems, but creates a whole range of other problems. And each requires slightly different coding patterns and practices. Knowing the strengths and weaknesses and understanding how memory management system(s) work goes hand-in-hand with writing clean, bug-free and maintainable code. Both compilers are covered in detail, as well as coding patterns required for writing cross-compiler code that must run under both. From manual memory management, to garbage collection, different memory management systems differ not only by the general category they fall in, but also by implementation. And all those fine implementation details also have a great impact on actual code. From the perspective of the everyday software development process discussing memory management is impossible without discussing its specific implementation in specific languages and toolsets.

Book Description
Get up to speed with creational, structural, behavioral and concurrent patterns in Delphi to write clear, concise and effective code Key FeaturesDelve into the core patterns and components of Delphi in order to master your application's designBrush up on tricks, techniques, and best practices to solve common design and architectural challengesChoose the right patterns to improve your program’s efficiency and productivityBook Description Design patterns have proven to be the go-to solution for many common programming scenarios. This book focuses on design patterns applied to the Delphi language. The book will provide you with insights into the language and its capabilities of a runtime library. You'll start by exploring a variety of design patterns and understanding them through real-world examples. This will entail a short explanation of the concept of design patterns and the original set of the 'Gang of Four' patterns, which will help you in structuring your designs efficiently. Next, you'll cover the most important 'anti-patterns' (essentially bad software development practices) to aid you in steering clear of problems during programming. You'll then learn about the eight most important patterns for each creational, structural, and behavioral type. After this, you'll be introduced to the concept of 'concurrency' patterns, which are design patterns specifically related to multithreading and parallel computation. These will enable you to develop and improve an interface between items and harmonize shared memories within threads. Toward the concluding chapters, you'll explore design patterns specific to program design and other categories of patterns that do not fall under the 'design' umbrella. By the end of this book, you'll be able to address common design problems encountered while developing applications and feel confident while building scalable projects. What you will learnGain insights into the concept of design patternsStudy modern programming techniques with DelphiKeep up to date with the latest additions and program design techniques in DelphiGet to grips with various modern multithreading approachesDiscover creational, structural, behavioral, and concurrent patternsDetermine how to break a design problem down into its component partsWho this book is for Hands-On Design Patterns with Delphi is aimed at beginner-level Delphi developers who want to build scalable and robust applications. Basic knowledge of Delphi is a must.

Book Description
Master Siemens TIA toolbox tools for efficient PLC and HMI code writing. Gain insights into algorithm performance, Delphi language intricacies, and program optimizations to enhance your skills effectively. Key Features Discover external programming libraries that will speed up your programming and code Learn to integrate external libraries into Delphi programs Build fast Delphi applications using concurrency, parallel programming, and memory management Book DescriptionPerformance matters! Users hate to use programs that are not responsive to interactions or run too slow to be useful. While becoming a programmer is simple enough, you require dedication and hard work to achieve an advanced level of programming proficiency where you know how to write fast code. This book begins by helping you explore algorithms and algorithmic complexity and continues by describing tools that can help you find slow parts of your code. Subsequent chapters will provide you with practical ideas about optimizing code by doing less work or doing it in a smarter way. The book also teaches you how to use optimized data structures from the Spring4D library, along with exploring data structures that are not part of the standard Delphi runtime library. The second part of the book talks about parallel programming. You’ll learn about the problems that only occur in multithreaded code and explore various approaches to fixing them effectively. The concluding chapters provide instructions on writing parallel code in different ways – by using basic threading support or focusing on advanced concepts such as tasks and parallel patterns. By the end of this book, you’ll have learned to look at your programs from a totally different perspective and will be equipped to effortlessly make your code faster than it is now.What you will learn Get to grips with algorithmic complexity and learn how to recognize it Use tools to determine program runtime behavior Speed up programs by doing less instead of more Discover the internal workings of Delphi data structures Gain an understanding of Delphi’s memory manager Find out how to write low-level parallel programs with TThread Use parallel patterns from the PPL and OTL libraries to write fast code Include external code, written in C or C++, in Delphi programs Who this book is for This book is for all Delphi programmers. Whether you’re a beginner or an accomplished programmer, you will find something interesting. Even though the focus is on the latest Delphi release, the code uses only standard Delphi syntax without syntactic additions from the latest releases, and most of it should compile and run in any Delphi from XE7 onward. If you’re using an older version of Delphi, don’t despair! Most of the concepts in this book do not depend on a specific Delphi version and will be useful for everyone.

Book Description
The overwhelming majority of bugs and crashes in computer programming stem from problems of memory access, allocation, or deallocation. Such memory related errors are also notoriously difficult to debug. Yet the role that memory plays in C and C++ programming is a subject often overlooked in courses and in books because it requires specialised knowledge of operating systems, compilers, computer architecture in addition to a familiarity with the languages themselves. Most professional programmers learn entirely through experience of the trouble it causes. This 2004 book provides students and professional programmers with a concise yet comprehensive view of the role memory plays in all aspects of programming and program behaviour. Assuming only a basic familiarity with C or C++, the author describes the techniques, methods, and tools available to deal with the problems related to memory and its effective use.
