X is the New York Times number 1 bestseller and thrilling, twenty-fourth book in the Kinsey Millhone Alphabet series from Sue Grafton. In hindsight, I marvel at how clueless I was . . . What I ask myself even now is whether I should have picked up the truth any faster than I did, which is to say not fast enough . . . When a glamorous red head wishes to locate the son she put up for adoption thirty-two years ago, it seems like an easy two hundred bucks for private investigator Kinsey Millhone. But when a cop tells her she was paid with marked bills, and Kinsey's client is nowhere to be found, it becomes apparent this mystery woman has something to hide. Riled, Kinsey won't stop until she's found out who fooled her and why. Meanwhile, the widow of the recently murdered P. I. – and Kinsey's old friend – Pete Wolinsky, needs help with her IRS audit. This seemingly innocuous task takes a treacherous turn when Kinsey finds a coded list amongst her friend's files. It soon leads her to an unhinged man with a catalogue of ruined lives left in his wake. And despite the devastation, there isn't a single conviction to his name. It seems this sociopath knows exactly how to cause chaos without leaving a trace. As Kinsey delves deeper into the investigation she quickly becomes the next target of this tormentor. But can Kinsey prove her case against him before she becomes the next victim?

High school sophomore Orville is only interested in making it through the summer, but then he discovers who is behind the brutal murder of a neighbor in his town on Cape Cod.

December, 1932 In the bathroom of a Belgian hotel, a French spymaster photographs top-secret documents – the operating instructions of the cipher machine, Enigma. A few weeks later a mathematician in Warsaw begins to decipher the coded communications of the Third Reich and lays the foundations for the code-breaking operation at Bletchley Park. The co-operation between France, Britain and Poland is given the cover-name 'X, Y & Z'. December, 1942 It is the middle of World War Two. The Polish code-breakers have risked their lives to continue their work inside Vichy France, even as an uncertain future faces their homeland. Now they are on the run from the Gestapo. People who know the Enigma secret are not supposed to be in the combat zone, so MI6 devises a plan to exfiltrate them. If it goes wrong, if they are caught, the consequences could be catastrophic for the Allies. Based on original research and newly released documents, X, Y & Z is the exhilarating story of those who risked their lives to protect the greatest secret of World War Two.

Scratch is a fun, free, beginner-friendly programming environment where you connect blocks of code to build programs. While most famously used to introduce kids to programming, Scratch can make computer science approachable for people of any age. Rather than type countless lines of code in a cryptic programming language, why not use colorful command blocks and cartoon sprites to create powerful scripts? In Learn to Program with Scratch, author Majed Marji uses Scratch to explain the concepts essential to solving real-world programming problems. The labeled, color-coded blocks plainly show each logical step in a given script, and with a single click, you can even test any part of your script to check your logic. You'll learn how to: –Harness the power of repeat loops and recursion –Use if/else statements and logical operators to make decisions –Store data in variables and lists to use later in your program –Read, store, and manipulate user input –Implement key computer science algorithms like a linear search and bubble sort Hands-on projects will challenge you to create an Ohm's law simulator, draw intricate patterns, program sprites to mimic line-following robots, create arcade-style games, and more! Each chapter is packed with detailed explanations, annotated illustrations, guided examples, lots of color, and plenty of exercises to help the lessons stick. Learn to Program with Scratch is the perfect place to start your computer science journey, painlessly. Uses Scratch 2

Secret sharing schemes form one of the most important topic in Cryptography. These protocols are used in many areas, applied mathematics, computer science, electrical engineering. A secret is divided into several pieces called shares. Each share is given to a user of the system. Each user has no information about the secret, but the secret can be retrieved by certain authorized coalition of users.This book is devoted to such schemes inspired by Coding Theory. The classical schemes of Shamir, Blakley, Massey are recalled. Survey is made of research in Combinatorial Coding Theory they triggered, mostly self-dual codes, and minimal codes. Applications to engineering like image processing, and key management of MANETs are highlighted.

It’s Valentine’s Day in Green Lawn! But Dink, Josh, and Ruth Rose just aren’t feeling the love this year. Valentine’s Day was so much more fun when they were little. Then they each start getting messages and clues from a secret admirer! Can the kids figure out who wants to be their Valentine? The alphabet may be over, but the mysteries continue in this eighth A to Z Mysteries Super Edition, featuring a 26-letter secret message hidden in the illustrations.

The inaugural Information Security Practice and Experience Conference (ISPEC) was held on April 11–14, 2005, in Singapore. As applications of information security technologies become pervasive, - sues pertaining to their deployment and operation are becoming increasingly important. ISPEC is intended to be an annual conference that brings together researchers and practitioners to provide a con?uence of new information se- rity technologies, their applications and their integration with IT systems in various vertical sectors. The Program Committee consisted of leading experts in the areas of information security, information systems, and domain experts in applications of IT in vertical business segments. The topics of the conference covered security applications and case studies, access control, network security, data security, secure architectures, and cryp- graphic techniques. Emphasis was placed on the application of security research to meet practical user requirements, both in the paper selection process and in the invited speeches. Acceptance into the conference proceedings was very competitive. The Call for Papers attracted more than 120 submissions, out of which the Program Committee selected only 35 papers for inclusion in the proceedings. Thisconferencewasmadepossibleonlythroughthecontributionsfrommany individuals and organizations. We would like to thank all the authors who s- mitted papers. We also gratefully acknowledge the members of the Program Committee and the external reviewers, for the time and e?ort they put into reviewing the submissions.
