Many examples are taken from real-world projects. The book focuses on high-level design as well as the gritty details of the Python syntax. The provided exercises inspire the reader to think about his or her own code, rather than providing solved problems. If you're new to Object Oriented Programming techniques, or if you have basic Python skills and wish to learn in depth how and when to correctly apply Object Oriented Programming in Python, this is the book for you. If you are an object-oriented programmer for other languages, you too will find this book a useful introduction to Python, as it uses terminology you are already familiar with. Python 2 programmers seeking a leg up in the new world of Python 3 will also find the book beneficial, and you need not necessarily know Python 2.

    Written by three prominent members of the Perl community who each have several years of experience teaching Perl around the world, this edition has been updated to account for all the recent changes to the language up to Perl 5.8.Perl is the language for people who want to get work done. It started as a tool for Unix system administrators who needed something powerful for small tasks. Since then, Perl has blossomed into a full-featured programming language used for web programming, database manipulation, XML processing, and system administration--on practically all platforms--while remaining the favorite tool for the small daily tasks it was designed for. You might start using Perl because you need it, but you'll continue to use it because you love it.Informed by their years of success at teaching Perl as consultants, the authors have re-engineered the Llama to better match the pace and scope appropriate for readers getting started with Perl, while retaining the detailed discussion, thorough examples, and eclectic wit for which the Llama is famous.The book includes new exercises and solutions so you can practice what you've learned while it's still fresh in your mind. Here are just some of the topics covered:Perl variable typessubroutinesfile operationsregular expressionstext processingstrings and sortingprocess managementusing third party modulesIf you ask Perl programmers today what book they relied on most when they were learning Perl, you'll find that an overwhelming majority will point to the Llama. With good reason. Other books may teach you to program in Perl, but this book will turn you into a Perl programmer.

    In this Spud Fit Challenge DIY guide, featuring twelve super simple (and cheap!) recipes and a variety of mindfulness techniques to help you reset your body and mind, he shows you the how's, what's and why's of his unusual regime - the tale of which went viral and captivated people across the globe. It's a scenario that will be depressingly familiar to all 'experienced dieters': towards the end of 2015, the former elite junior kayaker found himself more than 120 pounds (55kgs) overweight and feeling helpless, frustrated and in despair after yet another failed attempt at losing weight. With a lifetime of fad diets that only ever aimed to treat symptoms behind him, and armed only with the advice of 'the experts' whose discussion always began and ended with the message 'simply' to practise moderation, he had reached an impasse. Why couldn't he do moderation, like 'normal' people seemed to be able to? Sitting on the couch that day having reached his lowest point and not knowing the way out of the black hole that was swallowing his ability to enjoy life, he had that lightbulb moment: he was addicted to food. His mind raced - no other addict would ever be told to practise moderation, they would be told to quit their vice entirely. In that moment he realised that quitting food - or coming as close to it as possible - was the answer. Weeks of research told him that the humble potato, the food that has allowed vast populations to not only survive but to thrive over generations, was the perfect vehicle for his experiment: The Spud Fit Challenge was born! Good health is way more simple than we've been led to believe. There is a food that you can eat in abundance and that food provides you with all the nutrition your body needs to thrive for a long time. A good diet should not involve obsessing over every detail about what you put in your mouth - this does nothing to treat the underlying cause of your troubled relationship with food. This is the Spud Fit Challenge in a nutshell: let simplicity set you free. This guide will provide you with both the mental techniques that have helped Andrew to power through cravings without looking back as well as some ‘Spud Fit approved’ recipes to pique your interest - everything you need to successfully complete your own Spud Fit Challenge.

    The most common operation done with sed is substitution, replacing one block of text with another. awk is a complete programming language. Unlike many conventional languages, awk is "data driven" -- you specify what kind of data you are interested in and the operations to be performed when that data is found. awk does many things for you, including automatically opening and closing data files, reading records, breaking the records up into fields, and counting the records. While awk provides the features of most conventional programming languages, it also includes some unconventional features, such as extended regular expression matching and associative arrays. sed & awk describes both programs in detail and includes a chapter of example sed and awk scripts. This edition covers features of sed and awk that are mandated by the POSIX standard. This most notably affects awk, where POSIX standardized a new variable, CONVFMT, and new functions, toupper() and tolower(). The CONVFMT variable specifies the conversion format to use when converting numbers to strings (awk used to use OFMT for this purpose). The toupper() and tolower() functions each take a (presumably mixed case) string argument and return a new version of the string with all letters translated to the corresponding case. In addition, this edition covers GNU sed, newly available since the first edition. It also updates the first edition coverage of Bell Labs nawk and GNU awk (gawk), covers mawk, an additional freely available implementation of awk, and briefly discusses three commercial versions of awk, MKS awk, Thompson Automation awk (tawk), and Videosoft (VSAwk).

Everything is explained with pertinent real-world examples, often using Vagrant-managed virtual machines.

    Or, as #1 New York Times bestselling author and celebrity trainer Jorge Cruise explains: When we eat is as important as what we eat. Building on the scientifically proven but hard-to-sustain day-on, day-off technique known as "intermittent fasting," Cruise simplifies your calendar by dividing every day into two easy-to-remember nutritional zones: a 16-hour evening and overnight "burn zone" (semi-fasting) followed by an 8-hour "boost zone" (eating). To help you crush cravings throughout, he ingeniously introduces foods that can be consumed in either zone to keep you burning fat all around the clock. You'll never be hungry if you don't really ever have to fully fast! Putting the body on weight-loss autopilot, The Cruise Control Diet includes: * 50 recipes for deliciously unexpected boost-zone foods, such as Margherita pizza, spaghetti squash lasagna, and turmeric shrimp;* 15 high-fat, no-sugar burn-zone recipes for craving-quenching foods like chocolate coconut mousse and caramel chai latte;* Weekly menus and handy grocery lists to take guessing out of the equation;* Candid testimonials and amazing weight loss results from Cruise's clients;* An optional burn-zone exercise program with instructional photos.

    And if every page of these chapters does not proclaim to the reader that the only means for the realization of Truth is ahimsa, I shall deem all my labour in writing these chapters to have been in vain. And, even though my efforts in this behalf may prove fruitless, let the readers know that the vehicle, not the great principle, is at fault.- M. K. Gandhi

    Politicians and marketers present shoddy evidence for dubious claims all the time. But smart people make mistakes too, and when it comes to statistics, plenty of otherwise great scientists--yes, even those published in peer-reviewed journals--are doing statistics wrong."Statistics Done Wrong" comes to the rescue with cautionary tales of all-too-common statistical fallacies. It'll help you see where and why researchers often go wrong and teach you the best practices for avoiding their mistakes.In this book, you'll learn: - Why "statistically significant" doesn't necessarily imply practical significance- Ideas behind hypothesis testing and regression analysis, and common misinterpretations of those ideas- How and how not to ask questions, design experiments, and work with data- Why many studies have too little data to detect what they're looking for-and, surprisingly, why this means published results are often overestimates- Why false positives are much more common than "significant at the 5% level" would suggestBy walking through colorful examples of statistics gone awry, the book offers approachable lessons on proper methodology, and each chapter ends with pro tips for practicing scientists and statisticians. No matter what your level of experience, "Statistics Done Wrong" will teach you how to be a better analyst, data scientist, or researcher.

    But, like many skilled trades, the sign industry has been overrun by the techno-fueled promise of quicker and cheaper. The resulting proliferation of computer-designed, die-cut vinyl lettering and inkjet printers has ushered a creeping sameness into our visual landscape. Fortunately, there is a growing trend to seek out traditional sign painters and a renaissance in the trade. In 2010 filmmakers Faythe Levine, coauthor of Handmade Nation, and Sam Macon began documenting these dedicated practitioners, their time-honored methods, and their appreciation for quality and craftsmanship. Sign Painters, the first anecdotal history of the craft, features stories and photographs of more than two dozen sign painters working in cities throughout the United States.
