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
A trans-world journey with an extraorindary shorebird—from Australia's southern ocean to the Arctic and back—that explores the mysteries of the natural world and its power to heal. As the sun lowered and turned Gulf St Vincent fiery, they each called a high-pitched 'peeooowiii!', flashed their black wing-pits, spread their tail skirts and took flight... In a luminous new boook, Andrew Darby follows the odysseys of two seemingly-humble Grey Plovers, little-known migratory shorebirds, as they take previously uncharted ultramarathon flights from the southern coast of Australia to Arctic breeding grounds. On these death-defying flights they dodge predators, typhoons, exhaustion, and countless other dangers before they can breed...and then survive the jrouney all over again and return south to their feeding grounds. But the greatest threat to these, and other long-distance migrants on the flyway, is China's "dragon economy," which is engulfing their vital Yellow Sea staging spots. In Flight Lines, we meet the dedicated people of all nationalities and backgrounds working to save these intrepid birds, from Russia to Alaska, from the rim of the Arctic Sea to the coasts of the Southern Ocean. Out of their hard-won science Darby finds hope for the birds—an unexpected bright light for our times. But his journey to understand these marvellous birds almost ends when he is suddenly diagnosed with an incurable cancer. Then he finds science coming to his rescue too, as his own story and the journey of these little birds intersect in an unexpected and beautiful way.

Susan Cerulean’s memoir trains a naturalist’s eye and a daughter’s heart on the lingering death of a beloved parent from dementia. At the same time, the book explores an activist’s lifelong search to be of service to the embattled natural world. During the years she cared for her father, Cerulean also volunteered as a steward of wild shorebirds along the Florida coast. Her territory was a tiny island just south of the Apalachicola bridge where she located and protected nesting shorebirds, including least terns and American oystercatchers. I Have Been Assigned the Single Bird weaves together intimate facets of adult caregiving and the consolation of nature, detailing Cerulean’s experiences of tending to both. The natural world is the “sustaining body” into which we are born. In similar ways, we face not only a crisis in numbers of people diagnosed with dementia but also the crisis of the human-caused degradation of the planet itself, a type of cultural dementia. With I Have Been Assigned the Single Bird, Cerulean reminds us of the loving, necessary toil of tending to one place, one bird, one being at a time.
An engrossing memoir and eloquent portrait of place,The Thunder Treeshows how powerful the relationship between people and the natural world can be. "When people connect with nature, it happenssomewhere,"Pyle writes. "My own point of intimate contact with the land was a ditch... Without a doubt, most of the elements of my life flowed from that canal." The High Line Canal, originally built outside of Denver as part of an ambitious plan to bring water to eastern Colorado for irrigation, became the author's place of sanctuary and play, and his birthplace as a naturalist. This reprint of the classic book, updated with a new foreword by Richard Louv and a preface to this edition, makes one of Pyle's important early works once again available. For a new generation of readers, it offers a powerful argument for preserving opportunities for exploring nature.
