Discover the Ada programming language by being gently guided through the various parts of the language and its latest available stable release. The goal in this book is to slowly ease you into the different topics. It is understood that you do not always have ample free time, so the text is easy to digest and concepts are spoon fed to the reader. Starting with the simplest of topics, detailed explanations demonstrate the how and why of Ada. You are strongly encouraged to experiment and break things (without which the learning process is linear and quite dull). At the end of Beginning Ada Programming, you will have an excellent understanding of the general topics that make up the Ada programming language and can tackle far more challenging topics. Each chapter builds on what was previously described. Furthermore, each code example is independent of others and will run all by itself. Instructions are provided where you can obtain an Ada compiler and how to debug your code. What You Will Learn Master basic types, control structures, procedures, and functions in AdaUse Ada arrays, records, and access typesImplement OO programming using AdaHandle the basics of I/O and interfacing with the operating systemTake advantage of string operators, data containers, multiprocessing with tasks, and moreWork with contracts and proofs, networks, and various Ada libraries Who This Book Is For Programmers who are new to Ada, with at least some experience in programming, especially scientific programming.

Perl was originally written by Larry Wall while he was working at NASA’s Jet Propulsion Labs. Larry is an Internet legend, known not just for Perl, but as the author of the UNIX utilities rn, one of the original Usenet newsreaders, and patch, a tremendously useful tool that takes a list of differences between two files and allows you to turn one into the other. The term patch used for this activity is now widespread. Perl started life as a “glue” language for Larry and his officemates, allowing one to “stick” different tools together by converting between their various data formats. It pulled together the best features of several languages: the powerful regular expressions from sed (the Unix stream editor), the patte- scanning language awk, and a few other languages and utilities. The syntax was further made up out of C, Pascal, Basic, Unix shell languages, English, and maybe a few other elements along the way. While Perl started its life as glue, it is now more often likened to another handy multiuse tool: duct tape. A common statement heard in cyberspace is that Perl is the duct tape that holds the Internet together.
Program in assembly starting with simple and basic programs, all the way up to AVX programming. By the end of this book, you will be able to write and read assembly code, mix assembly with higher level languages, know what AVX is, and a lot more than that. The code used in Beginning x64 Assembly Programming is kept as simple as possible, which means: no graphical user interfaces or whistles and bells or error checking. Adding all these nice features would distract your attention from the purpose: learning assembly language. The theory is limited to a strict minimum: a little bit on binary numbers, a short presentation of logical operators, and some limited linear algebra. And we stay far away from doing floating point conversions. The assembly code is presented in complete programs, so that you can test them on your computer, play with them, change them, break them. This book will also show you what tools can be used, how to use them, and the potential problems in those tools. It is not the intention to give you a comprehensive course on all of the assembly instructions, which is impossible in one book: look at the size of the Intel Manuals. Instead, the author will give you a taste of the main items, so that you will have an idea about what is going on. If you work through this book, you will acquire the knowledge to investigate certain domains more in detail on your own. The majority of the book is dedicated to assembly on Linux, because it is the easiest platform to learn assembly language. At the end the author provides a number of chapters to get you on your way with assembly on Windows. You will see that once you have Linux assembly under your belt, it is much easier to take on Windows assembly. This book should not be the first book you read on programming, if you have never programmed before, put this book aside for a while and learn some basics of programming with a higher-level language such as C. What You Will LearnDiscover how a CPU and memory worksAppreciate how a computer and operating system work togetherSee how high-level language compilers generate machine language, and use that knowledge to write more efficient codeBe better equipped to analyze bugs in your programsGet your program working, which is the fun partInvestigate malware and take the necessary actions and precautions Who This Book Is For Programmers in high level languages. It is also for systems engineers and security engineers working for malware investigators. Required knowledge: Linux, Windows, virtualization, and higher level programming languages (preferably C or C++).

C is the programming language of choice when speed and reliability are required. It is used for many low-level tasks, such as device drivers and operating-system programming. For example, much of Windows and Linux is based on C programming. The updated 4th edition of Beginning C builds on the strengths of its predecessors to offer an essential guide for anyone who wants to learn C or desires a ‘brush-up’ in this compact, fundamental language. This classic from author, lecturer and respected academic Ivor Horton is the essential guide for anyone looking to learn the C language from the ground up.
