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.

Includes section, "Recent book acquisitions" (varies: Recent United States publications) formerly published separately by the U.S. Army Medical Library.

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

The biggest problem in American health care is us Do you know how to tell good health care from bad health care? Guess again. As patients, we wrongly assume the "best" care is dependent mainly on the newest medications, the most complex treatments, and the smartest doctors. But Americans look for health-care solutions in the wrong places. For example, hundreds of thousands of lives could be saved each year if doctors reduced common errors and maximized preventive medicine. For Dr. Robert Pearl, these kinds of mistakes are a matter of professional importance, but also personal significance: he lost his own father due in part to poor communication and treatment planning by doctors. And consumers make costly mistakes too: we demand modern information technology from our banks, airlines, and retailers, but we passively accept last century's technology in our health care. Solving the challenges of health care starts with understanding these problems. Mistreated explains why subconscious misperceptions are so common in medicine, and shows how modifying the structure, technology, financing, and leadership of American health care could radically improve quality outcomes. This important book proves we can overcome our fears and faulty assumptions, and provides a roadmap for a better, healthier future.

Some people plan to become administrators. The rest of us are thrust into it: we are webmasters, hobbyists, or just the default "technical people" on staff who are expected to keep things running. After some stumbling around repeating the same steps over and over again (and occasionally paying the price when we forget one), we realize that we must automate these tasks, or suffer endless frustration. Thus enters Perl.The Perl programming language is ideal for writing quick yet powerful scripts that automate many administrative tasks. It's modular, it's powerful, and it's perfect for managing systems and services on many platforms.Perl for System Administration is designed for all levels of administrators--from hobbyists to card-carrying SAGE members--sysadmins on multi-platform sites. Written for several different platforms (Unix, Windows NT, and Mac OS), it's a guide to the pockets of administration where Perl can be most useful for sites large and small, including: Filesystem management User administration with a dash of XML DNS and other network name services Database administration using DBI and ODBC Directory services and frameworks like LDAP and ADSI Using email for system administration Working with log files of all kinds Each chapter concentrates on a single administrative area, discusses the possible pitfalls, and then shows how Perl comes to the rescue. Along the way we encounter interesting Perl features and tricks, with many extended examples and complete programs. The scripts included in the book can simply be used as written or with minimal adaptation. But it's likely that readers will also get a taste of what Perl can do, and start extending those scripts for tasks that we haven't dreamed of.Perl for System Adminstration doesn't attempt to teach the Perl language, but it is an excellent introduction to the power and flexibility of Perl, and it whets the appetite to learn more. It's for anyone who needs to use Perl for system administration and needs to hit the ground running.

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
