Bring new power, performance, and scalability to your existing Perl code! Cure whatever ails your Perl code! Maintain, optimize, and scale any Perl software... whether you wrote it or not Perl software engineering best practices for enterprise environments Includes case studies and code in a fun-to-read format Today's Perl developers spend 60-80% of their time working with existing Perl code. Now, there's a start-to-finish guide to understanding that code, maintaining it, updating it, and refactoring it for maximum performance and reliability. Peter J. Scott, lead author of Perl Debugged, has written the first systematic guide to Perl software engineering. Through extensive examples, he shows how to bring powerful discipline, consistency, and structure to any Perl program-new or old. You'll discover how to: Scale existing Perl code to serve larger network, Web, enterprise, or e-commerce applications Rewrite, restructure, and upgrade any Perl program for improved performance Bring standards and best practices to your entire library of Perl software Organize Perl code into modules and components that are easier to reuse Upgrade code written for earlier versions of Perl Write and execute better tests for your software...or anyone else's Use Perl in team-based, methodology-driven environments Document your Perl code more effectively and efficiently If you've ever inherited Perl code that's hard to maintain, if you write Perl code others will read, if you want to write code that'll be easier for you to maintain, the book that comes to your rescue is Perl Medic. If you code in Perl, you need to read this book.–Adam Turoff, Technical Editor, The Perl Review. Perl Medic is more than a book. It is a well-crafted strategy for approaching, updating, and furthering the cause of inherited Perl programs.–Allen Wyke, co-author of several computer books including JavaScript Unleashed and Pure JavaScript. Scott's explanations of complex material are smooth and deceptively simple. He knows his subject matter and his craft-he makes it look easy. Scott remains relentless practical-even the 'Analysis' chapter is filled with code and tests to run.–Dan Livingston, author of several computer books including Advanced Flash 5: Actionscript in Action

Written for biomedical professionals and hospital practitioners interested in creating their own programs, Perl Programming for Medicine and Biology, discusses and reviews biomedical data resources, data standards, data organization, medicolegal and ethical conduct for data miners, and grants-related data sharing responsibilities. It teaches readers the basic Perl programming skills necessary for collecting, analyzing, and distributing biomedical data and provides solutions to in-depth problems that face researchers and healthcare professionals. Non-technical "Background" sections open each chapter to help non-programmers easily comprehend programming procedures. Explanations are provided for the biomedical issues underlying the Perl scripts that follow, and examples of real-world implementation are provided. Perl Programming for Medicine and Biology will show you how to transform, merge, and examine large and complex databases with ease.

Gisella Perl’s memoir is the extraordinarily candid account of women’s extreme efforts to survive Auschwitz. With writing as powerful as that of Charlotte Delbo and Ruth Kluger, her story individualizes and therefore humanizes a victim of mass dehumanization. Perl accomplished this by representing her life before imprisonment, in Auschwitz and other camps, and in the struggle to remake her life. It is also the first memoir by a woman Holocaust survivor and establishes the model for understanding the gendered Nazi policies and practices targeting Jewish women as racially poisonous. Perl’s memoir is also significant for its inclusion of the Nazis’ Roma victims as well as in-depth representations of Nazi women guards and other personnel. Unlike many important Holocaust memoirs, Perl’s writing is both graphic in its horrific detail and eloquent in its emotional responses. One of the memoir’s major historical contributions is Perl’s account of being forced to work alongside Dr. Josef Mengele in his infamous so-called clinic and using her position to save the lives of other women prisoners. These efforts including infanticide and abortion, topics that would remain silenced for decades and, unfortunately, continue to be marginalized from all too many Holocaust accounts. After decades out of print, this new edition will ensure the crucial place of Perl’s testimony on Holocaust memory and education.

Take the next step toward Perl mastery with advanced concepts that make coding easier, maintenance simpler, and execution faster. Mastering Perl isn't a collection of clever tricks, but a way of thinking about Perl programming for solving debugging, configuration, and many other real-world problems you’ll encounter as a working programmer. The third in O’Reilly’s series of landmark Perl tutorials (after Learning Perl and Intermediate Perl), this fully upated edition pulls everything together and helps you bend Perl to your will. Explore advanced regular expressions features Avoid common problems when writing secure programs Profile and benchmark Perl programs to see where they need work Wrangle Perl code to make it more presentable and readable Understand how Perl keeps track of package variables Define subroutines on the fly Jury-rig modules to fix code without editing the original source Use bit operations and bit vectors to store large data efficiently Learn how to detect errors that Perl doesn’t report Dive into logging, data persistence, and the magic of tied variables

This book offers a collection of 256 guidelines on the art of coding to help you write better Perl code--in fact, the best Perl code you possibly can. The guidelines cover code layout, naming conventions, choice of data and control structures, program decomposition, interface design and implementation, modularity, object orientation, error handling, testing, and debugging. - Publisher

This is the first attempt to explain how Jewish doctors survived extreme adversity in Auschwitz where death could occur at any moment. The ordinary Jewish slave labourer survived an average of fifteen weeks. Ross Halpin discovers that Jewish doctors survived an average of twenty months, many under the same horrendous conditions as ordinary prisoners. Despite their status as privileged prisoners Jewish doctors starved, froze, were beaten to death and executed. Many Holocaust survivors attest that luck, God and miracles were their saviors. The author suggests that surviving Auschwitz was far more complex. Interweaving the stories of Jewish doctors before and during the Holocaust Halpin develops a model that explains the anatomy of survival. According to his model the genesis of survival of extreme adversity is the will to live which must be accompanied by the necessities of life, specific personal traits and defence mechanisms. For survival all four must co-exist.

Too often, healthcare workers are led to believe that medical informatics is a complex field that can only be mastered by teams of professional programmers. This is simply not the case. With just a few dozen simple algorithms, easily implemented with open source programming languages, you can fully utilize the medical information contained in clini
