LINQ is the project name for a set of extensions to the .NET Framework that provide a generic approach to querying data from different data sources. LINQ will premier in Visual Studio 2008, and will become the next must–have skill for .NET developers. For more information about LINQ, you can check out the author’s portal at www.linqdev.com.

Pro LINQ: Language Integrated Query in C# 2008 is all about code.

Literally, this book starts with code and ends with code. In most books, the author shows the simplest example demonstrating how to use a method, but they so rarely show how to use the more complex prototypes. Pro LINQ: Language Integrated Query in C# 2008 is different. Demonstrating the overwhelming majority of LINQ operators and protoypes, it is a veritable treasury of LINQ examples.

Rather than obscure the relevant LINQ principles in code examples by focusing on a demonstration application you have no interest in writing, Pro LINQ: Language Integrated Query in C# 2008 cuts right to the chase of each LINQ operator, method, or class. However, where complexity is necessary to truly demonstrate an issue, the examples are right there in the thick of it. For example, code samples demonstrating how to handle concurrency conflicts actually create concurrency conflicts so you can step through the code and see them unfold.

Most books tell you about the simple stuff, while few books warn you of the pitfalls. Where Pro LINQ: Language Integrated Query in C# 2008 returns your investment is in the hours, and sometimes days, spent by the author determining why something may not work as expected. Sometimes this results in an innocent looking paragraph that may take you a minute to read and understand, but took days to research and explain.

Face it, most technical books while informative, are dull. LINQ need not be dull. Written with a sense of humor, Pro LINQ: Language Integrated Query in C# 2008 will attempt to entertain you on your journey through the wonderland of LINQ and C# 2008.

What you’ll learn

• How to leverage all the new LINQ relevant C# 2008 language features including extension methods, lambda expressions, anonymous data types, and partial methods.
• How to use LINQ to Objects to query in–memory data collections such as arrays, ArrayLists, and Lists to retrieve the data you want.
• Why some queries are deferred, how a deferred query can bite you, and how you can make deferred queries work for you.
• How to use LINQ to XML to revolutionize your creation, manipulation, and searching of XML data.
• How to query DataSets with LINQ to DataSet so you can co–exist with legacy code and use LINQ to query databases other than SQL Server.
• How to query Databases with LINQ to SQL, write your own entity classes, and understand how to handle concurrency conflicts.

Sam Lantinga, thank you for all the time and effort you put into helping the World of Warcraft community. Kevin M. Kelly, thank you for your odd sleep patterns and availability; exploration of the unknown is always easier when you have a friend with a map. Daniel Stephens, thank you for your help digging through various parts of the API and for giving me a good jumping-off point for my data exploration.

Chris Webb, thank you for bringing this book and Hacking World of Warcraft into existence. Both books serve as great resources for the WoW UI community. Maryann Steinhart, thank you for your guidance through the entire process. Your feedback, as always, has proved instrumental to the process. Matthew and Bryan, for working with me on this extremely ambitious project, it’s definitely been a rollercoaster.

Thanks to everyone who kept me moving when I needed a push, and those who slowed me down when I needed a break. Thank you to all of my users for putting up with bugs and lack of updates while the book was still being written; your patience and support is what keeps me writing addons. Finally, thank you to all the members of the WoW UI community for everything you do.--Jim

First, I would like to thank all those involved with the book: Jim for inviting me to take part; Bryan for sticking with it through all his work pressures; Chris, Maryann, and the rest of the folks at Wiley for allowing this project to materialize. Thanks to Rick and Stephen for picking apart our work. Supreme thanks go to Iriel, AnduinLothar, Cladhaire, MentalPower, Esamynn, Beladona, Krka, Legorol, Shirik, Cidan, Kevin, Sam, and all the members of #wow-lounge for putting up with our incessant questions. Thank you to all the folks who helped us churn out the API docs at the 11th hour.

Thank you to PepsiCo and Rockstar, Inc., without whose caffeinated beverages I never would have completed my chapters. I’d also like to thank whoever made the massage pad I keep on my computer chair. The best go out to the folks behind “Brisco County Jr.,” “Firefly,” and every other television series that should’ve gone on for years. For entertaining me in my few breaks, xkcd.org, bash.org, Portal, World of Warcraft, “Bones,” “Nip/Tuck,” and “Mythbusters” have my undying gratitude. What thanks for a book of this nature would be complete without recognition of Blizzard for its wonderful product and incredible passion?

Special thanks go out to my de facto colleagues from the UI & Macros forum for their hard work, dedication, and flaming of people who didn’t read the stickies while I devoted my time to this project: Troodi, the nicest troll I’ve ever met; Jelly, enthusiastic ForumToCPoster user; Kamdis, female Draenei—@@’nuff said; Lunessa, my no. 1 supporter for my presidential bid; Lopeppeppy, whose name I can finally type from memory; Kaydeethree, with the best diagram of how to find stickies ever; Kelfarr, under people’s skin before he even posts; Alestane, unnervingly patient; Valaron, never met a better Orc; Lealla, yay drood!; Aella, whom I always confuse with Lealla; everybody else whom I forgot to name; and our Administratrix Extraordinaire, Cairenn, for holding everything together!

My deepest thanks go to my family for making me who I am, and, most important, to my wife, Juliella, thank you for supporting me in this endeavor even when it meant I had to put you on /ignore from time to time.--Matthew

Wanda and Joe Newman, for the hours you put up with me not being willing to get off the computer. Thanks for all the support over the years, and for buying me my first copy of VB when I was 15, and sorry for all the arguments. Willis McLemore, thanks for supporting me without ever expecting anything from me.

Brent Miller, for helping me really start out on this awesome journey. You helped guide me when I first got started doing WoW addons, and many of the things we talked about helped shape me as a professional coder. Thanks for the first versions of Ace and for shrugging off all that responsibility onto me when you left. Oh, and thanks for listening to me rant.

Jim Whitehead and Matthew Orlando, you have been better co-authors than anyone else can ask for. Thanks for putting up with me while I learned how to do this, and for handling the content that I had no clue about. Sorry again for the times when I got overwhelmed. Thanks to all the editors and support from Wiley for helping me get through this, and for putting up with me when I gave you problems.

PProvost, Ammo, Cladhaire, hyperChipmunk, kergoth, Mikk, Nargiddley, pastamancer, nevcairiel, Tekkub, Tem, vhaar, Wobin and the members of #wowace. Thanks for the ideas, inspiration, strife, and hard work. Thanks for helping WowAce grow to more than a million users and for all the great mods!

Shirik, Tekkub, Wobin, Mentalpower, Esamynn, Cide, Ammo, Nevcairiel, and Iriel (and any I have accidentally forgotten). Thank you for helping so much on the reference. We would never have been done in time without you.

Karen Hobson. You’ve been a friend to me during some of the darkest times in my life, and I'll always treasure your company and support. I don’t think it’d be possible for me to thank you enough.

Aidan McLemore, who still thinks Daddy can do anything. Last, but by no means least, Kristina McLemore. Thanks for believing in me and following me across the country, for always loving me, and for helping me but, most important, for not divorcing me during the production of this book.--Bryan

A special thanks is owed to a group of hard-working members of the user interface community, without whom the reference section of this book would not have been completed. Each of you truly stepped up when we needed your help, and we’re extremely grateful for everything you’ve done for us. Thank you [Ammo], Beladona, Cide, Gazmik, JoshBorke, MentalPower, Nevcairiel, Shirik, Tem, and Wobin for giving us your time, and a little bit of your sanity.

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 matrix

Hackers 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.
