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).

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.

    We wonder why, for some people, success seems to come so naturally.Could the secret be how they were parented?This book unveils how parenting helped shape some of the most fascinating people you will ever encounter, by doing things that almost any parent can do. You don't have to be wealthy or influential to ensure your child reaches their greatest potential. What you do need is commitment--and the strategies outlined in this book.In The Formula: Unlocking the Secrets to Raising Highly Successful Children, Harvard economist Ronald Ferguson, named in a New York Times profile as the foremost expert on the US educational achievement gap, along with award-winning journalist Tatsha Robertson, reveal an intriguing blueprint for helping children from all types of backgrounds become successful adults.Informed by hundreds of interviews, the book includes never-before-published insights from the How I was Parented Project at Harvard University, which draws on the varying life experiences of 120 Harvard students. Ferguson and Robertson have isolated a pattern with eight roles of the Master Parent that make up the Formula: the Early Learning Partner, the Flight Engineer, the Fixer, the Revealer, the Philosopher, the Model, the Negotiator, and the GPS Navigational Voice.The Formula combines the latest scientific research on child development, learning, and brain growth and illustrates with life stories of extraordinary individuals--from the Harvard-educated Ghanian entrepreneur who, as the young child of a rural doctor, was welcomed in his father's secretive late-night political meetings; to the nation's youngest state-wide elected official, whose hardworking father taught him math and science during grueling days on the family farm in Kentucky; to the DREAMer immigration lawyer whose low-wage mother pawned her wedding ring to buy her academically outstanding child a special flute.The Formula reveals strategies on how you--regardless of race, class, or background--can help your children become the best they can be and shows ways to maximize their chances for happy and purposeful lives.

    At any given time, the brain is collecting, filtering, and analyzing information and, in response, performing countless intricate processes, some of which are automatic, some voluntary, some conscious, and some unconscious.Cognitive neuroscience is one of the ways we have to understand the workings of our minds. It's the study of the brain biology behind our mental functions: a collection of methods--like brain scanning and computational modeling--combined with a way of looking at psychological phenomena and discovering where, why, and how the brain makes them happen.Want to know more? Mind Hacks is a collection of probes into the moment-by-moment works of the brain. Using cognitive neuroscience, these experiments, tricks, and tips related to vision, motor skills, attention, cognition, subliminal perception, and more throw light on how the human brain works. Each hack examines specific operations of the brain. By seeing how the brain responds, we pick up clues about the architecture and design of the brain, learning a little bit more about how the brain is put together.Mind Hacks begins your exploration of the mind with a look inside the brain itself, using hacks such as "Transcranial Magnetic Stimulation: Turn On and Off Bits of the Brain" and "Tour the Cortex and the Four Lobes."
