It''s all in the name: Learn You a Haskell for Great Good! is a hilarious, illustrated guide to this complex functional language. Packed with the author''s original artwork, pop culture references, and most importantly, useful example code, this book teaches functional fundamentals in a way you never thought possible.You''ll start with the kid stuff: basic syntax, recursion, types and type classes. Then once you''ve got the basics down, the real black belt master-class begins: you''ll learn to use applicative functors, monads, zippers, and all the other mythical Haskell constructs you''ve only read about in storybooks.As you work your way through the author''s imaginative (and occasionally insane) examples, you''ll learn to:–Laugh in the face of side effects as you wield purely functional programming techniques–Use the magic of Haskell''s "laziness" to play with infinite sets of data–Organize your programs by creating your own types, type classes, and modules–Use Haskell''s elegant input/output system to share the genius of your programs with the outside worldShort of eating the author''s brain, you will not find a better way to learn this powerful language than reading Learn You a Haskell for Great Good!

The real challenge of programming isn''t learning a language''s syntax—it''s learning to creatively solve problems so you can build something great. In this one-of-a-kind text, author V. Anton Spraul breaks down the ways that programmers solve problems and teaches you what other introductory books often ignore: how to Think Like a Programmer. Each chapter tackles a single programming concept, like classes, pointers, and recursion, and open-ended exercises throughout challenge you to apply your knowledge.You''ll also learn how to:–Split problems into discrete components to make them easier to solve–Make the most of code reuse with functions, classes, and libraries–Pick the perfect data structure for a particular job–Master more advanced programming tools like recursion and dynamic memory–Organize your thoughts and develop strategies to tackle particular types of problemsAlthough the book''s examples are written in C++, the creative problem-solving concepts they illustrate go beyond any particular language; in fact, they often reach outside the realm of computer science. As the most skillful programmers know, writing great code is a creative art—and the first step in creating your masterpiece is learning to Think Like a Programmer.

Best selling guide to the inner workings of the Linux operating system with over 50,000 copies sold since its release in 2014. This in-depth guide to the various components of a Linux system covers topics like how the system boots, how networking works, and what the Linux kernel actually does.The Linux operating system is the power behind Android, Chromebooks, web servers, and the public cloud. It''s impossible to know for sure but there may well be over 60 million Linux users in the world. Developers and system maintainers need to understand how Linux works in order to use it effectively and fix it when it breaks. In this third edition of the best selling How Linux Works, author Brian Ward peels back the layers of this well-loved operating system to make Linux internals accessible. Readers learn how Linux boots, how the kernel manages devices and device drivers, and how processes, networking, interfaces, firewalls, and servers work. They also learn how Linux-based development tools work, how to use shared libraries, and how to write effective shell scripts. This edition has been thoroughly updated and expanded with added coverage of Logical Volume Manager (LVM), virtualization, and containers.

This highly anticipated print collection gathers articles published in the much-loved International Journal of Proof-of-Concept or Get The Fuck Out.PoC||GTFO follows in the tradition of Phrack and Uninformed by publishing on the subjects of offensive security research, reverse engineering, and file format internals. Until now, the journal has only been available online or printed and distributed for free at hacker conferences worldwide.Consistent with the journal''s quirky, biblical style, this book comes with all the trimmings: a leatherette cover, ribbon bookmark, bible paper, and gilt-edged pages. The book features more than 80 technical essays from numerous famous hackers, authors of classics like "Reliable Code Execution on a Tamagotchi," "ELFs are Dorky, Elves are Cool," "Burning a Phone," "Forget Not the Humble Timing Attack," and "A Sermon on Hacker Privilege." Twenty-four full-color pages by Ange Albertini illustrate many of the clever tricks described in the text.

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, exploiting cryptographic weaknesses, and perhaps even inventing new exploits. This book will teach you how to:– Program computers using C, assembly language, and shell scripts– Corrupt system memory to run arbitrary code using buffer overflows and format strings– Inspect processor registers and system memory with a debugger to gain a real understanding of what is happening– Outsmart common security measures like nonexecutable stacks and intrusion detection systems– Gain access to a remote server using port-binding or connect-back shellcode, and alter a server''s logging behavior to hide your presence– Redirect network traffic, conceal open ports, and hijack TCP connections– Crack encrypted wireless traffic using the FMS attack, and speed up brute-force attacks using a password probability matrixHackers are always pushing the boundaries, investigating the unknown, and evolving their art. Even if you don''t already know how to program, Hacking: The Art of Exploitation, 2nd Edition will give you a complete picture of programming, machine architecture, network communications, and existing hacking techniques. Combine this knowledge with the included Linux environment, and all you need is your own creativity.

Author Michal Zalewski has long been known and respected in the hacking and security communities for his intelligence, curiosity and creativity, and this book is truly unlike anything else out there.
