Master the basics of Python programming today! Python is on the rise in the world of coding and many popular technological devices from the Raspberry Pi to the Linux operating system use Python as a crux for not just education but implementation. Python can help you code your own software, develop your own games, and even format your own home surveillance system! It is, hands down, one of the most useful coding languages around, and the way it is formatted cuts out a great deal of the fluff that other coding languages have a tendency to be bogged down with. Whether your interest in Python is educational, career-based, or born out of a simple curiosity, it is a programming language you should know, be fluent in, and put on your resume. This world is quickly evolving into a technology-based society, and knowing a coding language as prominent as Python will not only ensure you a job in the future, but it will provide you with a thick foundation to then build your coding language on, should that be something you are chasing. However, no matter the purpose you have chosen for learning this language, there is no beginner’s audio guide that breaks down the language into its original components and strings them together cohesively better than this one. If you are looking for a guide that is easy to understand and still provides the easy to digest guidance you want, then look no further than here! 1. Language: English. Narrator: Kaleb Clark.

Hacking is the art of creative problem solving, whether that means finding an unconventional solution to a difficult problem or exploiting holes in sloppy programming. Many people call themselves hackers, but few have the strong technical foundation needed to really push the envelope. Rather than merely showing how to run existing exploits, author Jon Erickson explains how arcane hacking techniques actually work. To share the art and science of hacking in a way that is accessible to everyone, Hacking: The Art of Exploitation, 2nd Edition introduces the fundamentals of C programming from a hacker´s perspective. The included LiveCD provides a complete Linux programming and debugging environment all without modifying your current operating system. Use it to follow along with the book´s examples as you fill gaps in your knowledge and explore hacking techniques on your own. Get your hands dirty debugging code, overflowing buffers, hijacking network communications, bypassing protections, ex

For courses in Computer Science and Programming Computer systems: A Programmer?s Perspective explains the underlying elements common among all computer systems and how they affect general application performance. Written from the programmer?s perspective, this book strives to teach students how understanding basic elements of computer systems and executing real practice can lead them to create better programs. Spanning across computer science themes such as hardware architecture, the operating system, and systems software, the Third Edition serves as a comprehensive introduction to programming. This book strives to create programmers who understand all elements of computer systems and will be able to engage in any application of the field--from fixing faulty software, to writing more capable programs, to avoiding common flaws. It lays the groundwork for students to delve into more intensive topics such as computer architecture, embedded systems, and cybersecurity. This book focuses on systems that execute an x86-64 machine code, and recommends that students have access to a Linux system for this course. Students should have basic familiarity with C or C++. MasteringEngineering ® not included. Students, if MasteringEngineering is a recommended/mandatory component of the course, please ask your instructor for the correct ISBN and course ID. MasteringEngineering should only be purchased when required by an instructor. Instructors, contact your Pearson representative for more information. MasteringEngineering is an online homework, tutorial, and assessment product designed to personalize learning and improve results. With a wide range of interactive, engaging, and assignable activities, students are encouraged to actively learn and retain tough course concepts. Features + Benefits This title is a Pearson Global Edition. The Editorial team at Pearson has worked closely with educators around the world to include content which is especially relevant to students outside the United States. Computer Systems: A Programmer?s Perspective uses the following features to facilitate learning: NEW! The book now exclusively bases its presentation on x86-64 A carefully planned 12 chapter layout that covers all of the core topics of computer programming Chapter 1 uses a simple ?hello world? program to introduce the major concepts and themes of computer programming. Chapter 2 dives into the topic of computer arithmetic, considering how numbers are represented in computer programs and how they affect value coding. The chapter places a special emphasis on the properties of unsigned and two?s-compliment number representations. It gives students necessary insight into arithmetic from the programmers perspective and why it?s so important. Chapter 3 teaches students how to read the x86-64 code generated by a C compiler, covering the basic instruction patterns for different control constructs, implementation procedures, and the allocation of different data structures. This chapter also discusses the implementation of integer and floating point arithmetic and takes a machine-level view of programs to understand certain code vulnerabilities. Chapter 4 introduces students to basic combinational and sequential logic elements and shows how they can be used in a simplified subset of the x86-64 instruction set called Y86-64. It starts with a single-cycle datapath and moves onto a discussion of pipelining. Chapter 5 gives students techniques for improving code performance with transformations that reduce work and enhance instruction-level parallelism. Chapter 6 covers different types of RAM and ROM memory systems, describing their hierarchical arrangement. The chapter makes the abstract concept tangible by using the analogy of a ?memory mountain? with ridges of temporal locality and slopes of spatial locality. Students learn that improving temporal and spatial locality improves performance. Chapter 7 discusses both static and dynamic linking, areas included in most systems text where programmers make their most confusing errors. Chapter 8 explains exceptional control flow at all levels of the system, from simple hardware interrupts to nonlocal jumps in C that break the stack discipline. This chapter introduces the fundamental idea of a process by teaching students how it works and how it is created and manipulated from application programs. Chapter 9 shows students key characteristics of the virtual memory system and how it works, addressing issues such
