Programming with C++20 teaches programmers with C++ experience the new features of C++20 and how to apply them. It does so by assuming C++11 knowledge. Elements of the standards between C++11 and C++20 will be briefly introduced, if necessary. However, the focus is on teaching the features of C++20. You will start with learning about the so-called big four Concepts, Coroutines, std::ranges, and modules. The big four a followed by smaller yet not less important features. You will learn about std::format, the new way to format a string in C++. In chapter 6, you will learn about a new operator, the so-called spaceship operator, which makes you write less code. You then will look at various improvements of the language, ensuring more consistency and reducing surprises. You will learn how lambdas improved in C++20 and what new elements you can now pass as non-type template parameters. Your next stop is the improvements to the STL. Of course, you will not end this book without learning about what happened in the constexpr-world.
One of the problems that C++ programmers face using templates is understanding the complex syntax. Mastering Templates can be a game-changer when programming C++, as it is a powerful feature for writing clean code. In this book from the Notebook C++ series, I show you tips and tricks on how to write templates efficiently. It starts with the basics, like the different template parameter types and techniques like always_false. You’ll then learn more about best practices. For example, where to put the enable_if and how to disable a special member function. Notebook C++: Tips and Tricks with Templates is a quick-reference book where you can find the information the moment you need it for programming.
Brought together by a brutal murder, a psychological profiler who’s lost her memory and a teenage boy with a fiercely guarded secret become unwitting, unlikely partners in this race to stop a killer—“Nordic noir at its best” (Booklist, starred review). Named the Best Nordic Crime Novel of the Year by the Crime Writers of Scandinavia Out of the frozen depths of a forest in Ormberg, Sweden, a woman stumbles onto the road. Her arms are covered with scratches, her feet are bare, and she has no memory of who she is. Local police identify her as psychological profiler Hanne Lagerlind-Schön, who, with her partner, had been helping investigate the cold case of a young woman’s murder. Hanne begins to recover but cannot recall anything about where her partner is, or what their investigation had uncovered before her disappearance. Police have only one lead: a young woman in a sequined dress who was spotted nearby the night Hanne was found. The young woman doesn’t come forward because she doesn’t exist: Jake Birgersson, a local teenager, had been out walking in his mother’s dress and sister’s makeup, his secret shame and thrill. Terrified of discovery, Jake hid and watched Hanne get into a car, leaving behind her diary. Reading Hanne’s notebook, Jake realizes that it contains the key to a major breakthrough in the case—but turning it in would mean admitting the truth about who he is. When another murder victim is found in the woods, Jake realizes that Hanne herself is in danger, and his only choice is to find and warn her so that together, they can stop the killer before he strikes again. Praise for After She’s Gone “[A] stellar crime novel . . . Grebe delivers an unflinching, heart-wrenching message about the plight of refugees in this scorching thriller.”—Publishers Weekly (starred review)

Translated into English for the first time, The Archeologist is a landmark of Greek national literature, and an important document in the history of archeology and classicism. Published for the bicentennial year of the outbreak of the Greek War of Independence. A Penguin Classic The year 2021 marks the bicentennial of the outbreak of the Greek War of Independence. This historical milestone provides the impetus for a new period of intensified reflection on the past, present, and future of Greece, especially in light of recent financial and humanitarian challenges the country has found itself facing: the debt crisis that began in the last days of 2009 and the migration crisis five years later. These crises had already stirred renewed and often animated debate about Greek national identity, especially in relation to Europe, and the legacy of classical antiquity remains central to how that relationship is imagined. Where does Greece fit into the modern world and what role, if any, should its celebrated and idealized antiquity play in the country's national identity? More than a century ago, Karkavitsas's The Archeologist (1904) helped to articulate and frame these kinds of questions. The work is an allegory of Greek nationalism that is stylized as a folktale about Aristodemus and Dimitrakis Eumorphopoulos, two brothers and descendants of the illustrious Eumorphopoulos line. For centuries, the family had been persecuted by the Khan family, but when the Khan dynasty starts to topple, the Eumorphopoulos family resolves to regain their ancestral lands and restore their line's ancient glory. Yet the two brothers disagree about the best path forward into the future. Aristodemus insists, to the point of mania, that they must look only to the ancient past—to the family's ancient language, texts, religion, and monuments; Dimitrakis, on the other hand, exuberantly embraces the present. The Archeologist, however, attempts to map and dramatize the tensions that were violently brewing in the Balkans at the turn of the twentieth century and which, within a decade of the work's publication, would contribute to the outbreak of World War I. Also included in this edition are a selection of "sea tales," which Karkavitsas heard from sailors during his extensive time aboard ships in the Mediterranean. Considered as indigenous to Greek literature, the four sea stories represent some of the best known of the Tales from the Prow. "The Gorgon," one of Karkavitsas's shortest sea stories, is also one of the most famous.
Machine learning has become an integral part of many commercial applications and research projects, but this field is not exclusive to large companies with extensive research teams. If you use Python, even as a beginner, this book will teach you practical ways to build your own machine learning solutions. With all the data available today, machine learning applications are limited only by your imagination. You’ll learn the steps necessary to create a successful machine-learning application with Python and the scikit-learn library. Authors Andreas Müller and Sarah Guido focus on the practical aspects of using machine learning algorithms, rather than the math behind them. Familiarity with the NumPy and matplotlib libraries will help you get even more from this book. With this book, you’ll learn: Fundamental concepts and applications of machine learning Advantages and shortcomings of widely used machine learning algorithms How to represent data processed by machine learning, including which data aspects to focus on Advanced methods for model evaluation and parameter tuning The concept of pipelines for chaining models and encapsulating your workflow Methods for working with text data, including text-specific processing techniques Suggestions for improving your machine learning and data science skills
“Badura-Skoda addresses the place of the piano in the eighteenth century from the perspective of a scholar and performer” (Eighteenth-Century Music). In the late seventeenth century, Italian musician and inventor Bartolomeo Cristofori developed a new musical instrument—his cembalo che fa il piano e forte, which allowed keyboard players flexible dynamic gradation. This innovation, which came to be known as the hammer-harpsichord or fortepiano grand, was slow to catch on in musical circles. However, as renowned piano historian Eva Badura-Skoda demonstrates, the instrument inspired new keyboard techniques and performance practices and was eagerly adopted by virtuosos of the age, including Scarlatti, J. S. Bach, Clementi, Haydn, Mozart, and Beethoven. Presenting a rich array of archival evidence, Badura-Skoda traces the construction and use of the fortepiano grand across the musical cultures of eighteenth-century Europe, providing a valuable resource for music historians, organologists, and performers. “Badura-Skoda has written a remarkable volume, the result of a lifetime of scholarly research and investigation. . . . Essential.” —Choice
