Book Description
Most Perl programmers were originally trained as C and Unix programmers, so the Perl programs that they write bear a strong resemblance to C programs. However, Perl incorporates many features that have their roots in other languages such as Lisp. These advanced features are not well understood and are rarely used by most Perl programmers, but they are very powerful. They can automate tasks in everyday programming that are difficult to solve in any other way. One of the most powerful of these techniques is writing functions that manufacture or modify other functions. For example, instead of writing ten similar functions, a programmer can write a general pattern or framework that can then create the functions as needed according to the pattern. For several years Mark Jason Dominus has worked to apply functional programming techniques to Perl. Now Mark brings these flexible programming methods that he has successfully taught in numerous tutorials and training sessions to a wider audience.* Introduces powerful programming methodsnew to most Perl programmersthat were previously the domain of computer scientists* Gradually builds up confidence by describing techniques of progressive sophistication* Shows how to improve everyday programs and includes numerous engaging code examples to illustrate the methods

Book Description
Many programmers would love to use Perl for projects that involve heavy lifting, but miss the many traditional algorithms that textbooks teach for other languages. Computer scientists have identified many techniques that a wide range of programs need, such as: Fuzzy pattern matching for text (identify misspellings!) Finding correlations in data Game-playing algorithms Predicting phenomena such as Web traffic Polynomial and spline fitting Using algorithms explained in this book, you too can carry out traditional programming tasks in a high-powered, efficient, easy-to-maintain manner with Perl.This book assumes a basic understanding of Perl syntax and functions, but not necessarily any background in computer science. The authors explain in a readable fashion the reasons for using various classic programming techniques, the kind of applications that use them, and -- most important -- how to code these algorithms in Perl.If you are an amateur programmer, this book will fill you in on the essential algorithms you need to solve problems like an expert. If you have already learned algorithms in other languages, you will be surprised at how much different (and often easier) it is to implement them in Perl. And yes, the book even has the obligatory fractal display program.There have been dozens of books on programming algorithms, some of them excellent, but never before has there been one that uses Perl.The authors include the editor of The Perl Journal and master librarian of CPAN; all are contributors to CPAN and have archived much of the code in this book there."This book was so exciting I lost sleep reading it."

Book Description
The twentieth-anniversary edition of Marion Blumenthal Lazan’s acclaimed Holocaust memoir features new material by the author, a reading group guide, a map, and additional photographs. “The writing is direct, devastating, with no rhetoric or exploitation. The truth is in what’s said and in what is left out.”—ALA Booklist (starred review) Marion Blumenthal Lazan’s unforgettable and acclaimed memoir recalls the devastating years that shaped her childhood. Following Hitler’s rise to power, the Blumenthal family—father, mother, Marion, and her brother, Albert—were trapped in Nazi Germany. They managed eventually to get to Holland, but soon thereafter it was occupied by the Nazis. For the next six and a half years the Blumenthals were forced to live in refugee, transit, and prison camps, including Westerbork in Holland and Bergen-Belsen in Germany, before finally making it to the United States. Their story is one of horror and hardship, but it is also a story of courage, hope, and the will to survive. Four Perfect Pebbles features forty archival photographs, including several new to this edition, an epilogue, a bibliography, a map, a reading group guide, an index, and a new afterword by the author. First published in 1996, the book was an ALA Notable Book, an ALA Quick Pick for Reluctant Readers, and IRA Young Adults’ Choice, and a Notable Trade Book in the Field of Social Studies, and the recipient of many other honors. “A harrowing and often moving account.”—School Library Journal

Book Description
How to release productivity guilt and embrace the hidden values in our daily lives. Any given day brings a never-ending list of things to do. There’s the work thing, the catch-up thing, the laundry thing, the creative thing, the exercise thing, the family thing, the thing we don’t want to do, and the thing we’ve been putting off, despite it being the most important thing. Even on days when we get a lot done, the thing left undone can leave us feeling guilty, anxious, or disappointed. After five years of searching for the secret to productivity, Madeleine Dore discovered there isn’t one. Instead, we’re being set up to fail. I Didn’t Do the Thing Today is the inspiring call to take productivity off its pedestal—by dismantling our comparison to others, aspirational routines, and the unrealistic notions of what can be done in a day, we can finally embrace the joyful messiness and unpredictability of life. For anyone who has ever felt the pressure to do more, be more, achieve more, this antidote to our doing-obsession is the permission slip we all need to find our own way.
