Software developers need to worry about security as never before. They need clear guidance on safe coding practices, and that´s exactly what this book delivers. The book does not delve deep into theory, or rant about the politics of security. Instead, it clearly and simply lays out the most common threats that programmers need to defend against. It then shows programmers how to make their defense. The book takes a broad focus, ranging over SQL injection, worms and buffer overflows, password security, and more. It sets programmers on the path towards successfully defending against the entire gamut of security threats that they might face.
There are a growing number of users today who are turning to C for safety-critical development and many safety-critical systems are being written in C. However, there is no guidance available for the use of C in safety related work. This book provides developers and programmers with an essential critique of existing standards initiatives for safety critical development and an in-depth critique of the C language from a safety viewpoint. The book contains many new areas, specifically, intrinsic software quality which is expected to be of considerable importance in the near future and discusses how to build product quality into the software process using publicly available tools.
Why just get by in F# when you can program in style! This book goes beyond syntax and into design. It provides F# developers with best practices, guidance, and advice to write beautiful, maintainable, and correct code. Stylish F# covers every design decision that a developer makes in constructing F# programs, helping you make the most educated and valuable design choices at every stage of code development. You will learn about the design of types and function signatures, the benefits of immutability, and the uses of partial function application. You will understand best practices for writing APIs to be used by F#, C#, and other languages. Each carefully vetted design choice is supported with compelling examples, illustrations, and rationales. What You´ll Learn Know why, when, and how to code in immutable style Use collection functions, piping, and function composition to build working software quickly Be aware of the techniques available to bring error handling into the mainstream of program logic Optimize F# code for maximum performance Identify and implement opportunities to use function injection to improve program design Appreciate the methods available to handle unknown data values Understand asynchronous and parallel programming in F#, and how it differs from C# asynchronous programming Who This Book Is For Any developer who writes F# code and wants to write it better
