    In 1985, a new version of the language was developed, incorporating additional features such as multiple input files, dynamic regular expressions, and user-defined functions. This new version is available for both Unix and MS-DOS. This is the first book on AWK. It begins with a tutorial that shows how easy AWK is to use. The tutorial is followed by a comprehensive manual for the new version of AWK. Subsequent chapters illustrate the language by a range of useful applications, such as: Retrieving, transforming, reducing, and validating data Managing small, personal databases Text processing Little languages Experimenting with algorithms The examples illustrates the books three themes: showing how to use AWK well, demonstrating AWKs versatility, and explaining how common computing operations are done. In addition, the book contains two appendixes: summary of the language, and answers to selected exercises.

    For Alex Troutt, a trip back home for a much-needed summer vacation proves only one thing: greed rules. But how it takes root could destroy her world. Fueled by the lust of power and money, the shadow of death envelopes her seaside hometown, including those closest to Alex. But as disconnected investigations converge into one focal point, Alex will stop at nothing to blow the entire crime ring straight to hell—even if she has to make the ultimate sacrifice…her life. AT Dusk (Book 5) Eyes are the window to the soul…unless there isn't a soul to be found.  A little boy makes his first kill—and he likes it. He is cunning, charming, and without remorse.      He is a sociopath.     As boy turns to man, what lies inside takes root. He will make a mark on Boston unlike any other, and FBI Special Agent Alex Troutt must figure out how to stop him.     But when she and her close-knit team move in closer, the stakes become much higher as the case takes on a more personal tone. It’s a frantic race to stop a manipulative killer before his web of deceit and destruction escalates into a blood bath of haunting proportions.  AT Last (Book 6) Thirty years after losing a parent to a hit-and-run drunk driver, FBI agent Alex Troutt finally confronts the killer--the same man who just murdered the Boston police chief. And what Alex pulls from him shatters her core. Armed with little more than hope and a shred of decades-old evidence, Alex chases a memory from her past, hoping that she'll find the mother she never really had. With her old buddy Archie on board --as much as ever can be -- the hunt takes her deep into the foothills of West Virginia. A fanatical religious cult has created its own society. Clinging to a whisper of hope, Alex must out-think and out-duel everyone in her path to right a thirty-year wrong. Will Alex’s quest to find the truth destroy her life all over again?

    This is necessary because, in the words of Michael Polanyi, "we can know more than we can tell." Our design choices are not the result of an ineluctable chain of logic; they come from a deeper place, one which is visceral and inarticulate.Polanyi calls this "tacit knowledge", a thing which we only understand as part of something else. When we speak, we do not focus on making sounds, we focus on our words. We understand the muscular act of speech, but would struggle to explain it.To write software, we must learn where to draw boundaries. Good software is built through effective indirection. We seem to have decided that this skill can only be learned through practice; it cannot be taught, except by example. Our decisions may improve with time, but not our ability to explain them. It's true that the study of these questions cannot yield a closed-form solution for judging software design. We can make our software simple, but we cannot do the same to its problem domain, its users, or the physical world. Our tacit knowledge of this environment will always inform our designs.This doesn't mean that we can simply ignore our design process. Polanyi tells us that tacit knowledge only suffices until we fail, and the software industry is awash with failure. Our designs may never be provably correct, but we can give voice to the intuition that shaped them. Our process may always be visceral, but it doesn't have to be inarticulate.And so this book does not offer knowledge, it offers clarity. It is aimed at readers who know Clojure, but struggle to articulate the rationale of their designs to themselves and others. Readers who use other languages, but have a passing familiarity with Clojure, may also find this book useful.

    You could spend years discovering solutions to them all, step by step as you encounter them. Or you can just look in here. All successful database applications are destined to eventually run into issues scaling up their performance. Peek into the future of your PostgreSQL database's problems today. Know the warning signs to look for, and how to avoid the most common issues before they even happen. Surprisingly, most PostgreSQL database applications evolve in the same way: Choose the right hardware. Tune the operating system and server memory use. Optimize queries against the database, with the right indexes. Monitor every layer, from hardware to queries, using some tools that are inside PostgreSQL and others that are external. Using monitoring insight, continuously rework the design and configuration. On reaching the limits of a single server, break things up; connection pooling, caching, partitioning, and replication can all help handle increasing database workloads. The path to a high performance database system isn't always easy. But it doesn't have to be mysterious with the right guide. This book is a clear, step-by-step guide to optimizing and scaling up PostgreSQL database servers. - Publisher.

    Through concrete examples and jargon-free explanations, this book teaches you how to apply functional programming to real-life development tasks. The book includes insightful comparisons to object-oriented or imperative programming, which will allow you to ease into functional design. Moreover, you'll learn a repertoire of techniques including function chaining and pipelining, recursion, currying, binding, functional composition, lazy evaluation, fluent error handling, memoization, and much more. By the end of the book, you'll think about application design in a fresh new way.About the technologyAs web developers build increasingly complex applications in JavaScript, the code base for these projects can become exponentially larger and harder to maintain. The result? Application performance suffers, and readability and extensibility are severely compromised. For applications like these, Functional Programming provides a saner approach, allowing you to write elegant, readable code that raises the level of abstraction while being less prone to errors. Although not a "pure" functional language, JavaScript's native functional capabilities unlock access to proven functional programming techniques and practices.What's insideFoundations of functional programming and designExplore JavaScript's functional programming capabilities and the functional library ecosystemCreate more reliable code by embracing immutabilityLearn to write code that's easier to reason aboutSeparate core logic from program structure to write extensible codeAdopt a new approach to error handling and testingApply functional programming to solve real-world problemsAbout the readerReaders need to be comfortable with JavaScript programming and object-oriented design. No previous experience with functional programming is required.About the authorLuis Atencio is a Staff Software Engineer for Citrix Systems in Ft. Lauderdale, FL.

    In 1964, I embarked on a journey that was to be my life's adventure.  I hired on as a pilot for Air America and its clandestine operations in Southeast Asia.      Flying for the CIA's secret airline was a dream come true.  Air America's operations were unknown.  Its schedules were irregular.  Its pilots were shadow people.  It was the world of spooks, covert air ops and adventure.  I had already been a pilot for more than half of my life when I left my home in Detroit for the wild escapades that awaited me in Southeast Asia.  Air America had been the pinnacle of my life and, had the trajectory remained steady, my world and my career should have gone onward and upward from that point.      The intent of telling my story is to take the reader on an historical journey of a little-known place in time through my own personal account.  Within the context of history, my narrative is not to be considered anything but my own experience.     The ranks of Air America were comprised of a host of patriotic professionals who deserve a place of honor in the annals of history.  However, many colorful characters wore the Air America wings, and inside the course of my narrative, the reader will be subjected to people and situations that cannot be filed neatly under anything resembling normal sanity.      Most names, except those of a known or high-ranking or public nature, and those I wish to recognize for heroic performances, have been changed to protect the innocent and guilty alike.

    The book transported my imagination where I was right inside a courtroom drama…. Fantastic, thoroughly recommend this book!” “Both educational and entertaining …I thought the author did an excellent job of introducing Americans to the British legal system (which bemuses many of us as much as cricket). I always love good summations, and these were of high calibre… The author demonstrated a mastery of providing meaningful snippets of personal life essentially in textual asides.”“Author John Burton, Q.C. knows of whereof he writes, and his book, as well as being a well plotted, well written and highly enjoyable murder trial novel, is an education in the English criminal justice system, warts and all… There is also a fascinating subplot about the business of English criminal lawyers and the intrigues of the “Chambers” in which Brant practices.”“…..the skills of both the Prosecution, Joanna Glass QC and the Defence are on display. The reader is made to feel part of the Defence team.”David Brant QC is a newly appointed Queen’s Counsel, a “Silk”, a Criminal Barrister struggling against ever-dwindling legal aid funds and a lack of work. His Chambers is also suffering internal and external pressures and his Senior Clerk seems to only serve a select few. Life at the Bar is more challenging than ever before. His personal life is not much better. Having faced an acrimonious divorce after an inadvisable liaison with a female Solicitor, his life has become a mixture of enforced rest and ever increasing consumption of Claret and Rioja Reserva. However, after a night out with his Senior Clerk, he is instructed to defend in a Murder trial, leading one of the instructing solicitor’s firm’s In-House Barristers.The client is a Mr Damien Clarke, a cocaine addict charged with killing a known associate, Usman Hussain, after a night of smoking crack together in Hussain’s flat. The evidence against Damien appears almost overwhelming and as the case progresses towards trial it is strengthened by further forensic scientific evidence.David Brant QC must use all his forensic skill to combat the array of damning evidence against Damien and to pit his wits against a highly competent Prosecutor and a Judge who has a personal dislike for him. The Silk Brief takes us from before David Brant QC is instructed, through his early preparation of the case and conferences with the client in the High Security Belmarsh prison, through to the trial and verdict. It provides the day by day record of a murder trial including the examination and cross-examination of lay and expert witnesses, Counsel’s speeches, the Judges summing up and finally the jury’s deliberations and verdict. Although a work of fiction, the author draws extensively on his knowledge of the Criminal Bar of England and Wales, having practiced as a Criminal Barrister for over thirty years, latterly as Queen’s Counsel, conducting many trials, including murder trials in the Central Criminal Court, known colloquially and fondly as “The Old Bailey”.
