The Hitchhiker's Guide to Python takes the journeyman Pythonista to true expertise. More than any other language, Python was created with the philosophy of simplicity and parsimony. Now 25 years old, Python has become the primary or secondary language (after SQL) for many business users. With popularity comes diversity-and possibly dilution.This guide, collaboratively written by over a hundred members of the Python community, describes best practices currently used by package and application developers. Unlike other books for this audience, The Hitchhiker's Guide is light on reusable code and heavier on design philosophy, directing the reader to excellent sources that already exist.

Das Buch spielt mit einem neuen, ganzheitlichen Vorstellungsbild des Menschen, der aus drei Einheiten zusammengesetzt gedacht wird: das analytische Denken residiert in einer computerahnlichen linken Gehirnhalfte, die kreative Intuition sitzt wie ein naturbelassenes neuronales Netzwerk in der rechten. Der Mensch denkt, wohin ihn das dritte System lenkt: Ein hyperschneller Anzeichen-Identifizierer alarmiert etwa bei gefahrlichen Ereignissen die Aufmerksamkeit, unbewusst, ohne Denken. Bis auf ein paar Zeilen mathematischer Erklarung ist dieses Buch fulminante Philosophie. Wichtige Ansichten dieser Welt werden gedreht und bleiben zum Teil auf dem Kopf stehen. Die Lehren von Platon, Aristoteles, Konfuzius, Epikur, Freud & Co. erscheinen als notwendige Philosophien verschiedener Gehirnnutzungsvarianten. Das Buch ist eine scharfsinnig-bissig-humorvolle und sehr personliche Auseinandersetzung mit dem, was wir "Lebenssinn" nennen.

Description Why use several languages for a web application when you only need one? Node.js is a server-side platform and runtime that readers can use to build full stack web applications entirely in JavaScript! Get Programming with Node.js teaches readers to write server-side code in JavaScript using Node.js.

Have you ever felt frustrated working with someone else's code? Difficult-to-maintain source code is a big problem in software development today, leading to costly delays and defects. Be part of the solution. With this practical book, you'll learn 10 easy-to-follow guidelines for delivering Java software that's easy to maintain and adapt. These guidelines have been derived from analyzing hundreds of real-world systems. Written by consultants from the Software Improvement Group (SIG), this book provides clear and concise explanations, with advice for turning the guidelines into practice. Examples for this edition are written in Java, while our companion C# book provides workable examples in that language. Write short units of code: limit the length of methods and constructors Write simple units of code: limit the number of branch points per method Write code once, rather than risk copying buggy code Keep unit interfaces small by extracting parameters into objects Separate concerns to avoid building large classes Couple architecture components loosely Balance the number and size of top-level components in your code Keep your codebase as small as possible Automate tests for your codebase Write clean code, avoiding "code smells" that indicate deeper problems

Eingebettete Systeme begegnen uns mittlerweile uberall im Alltag: vom Mikrocontroller in der Waschmaschine bis hin zum leistungsfahigen DSP im Autoradio. Noch vor wenigen Jahren wurden diese Prozessoren aufwandig in Assembler programmiert und besassen nur in den wenigsten Fallen ein Betriebssystem. Mittlerweile aber bieten leistungsfahige und schlanke Linux-Derivate auch auf einfachen Prozessoren den Komfort der Schnittstellentreiber, des Multi-Threadings und eines Dateisystems. Die vorgestellte Hardware ist teilweise Konsumerprodukten entlehnt und somit gut erhaltlich.

Besonderer Wert wird auf die Praxistauglichkeit der Implementierungen gelegt, und so sind die Beispiele zur Hardwareanbindung via I2C, zur Kommunikation und zur Bildverarbeitung vollstandig durchimplementiert und online frei verfugbar. Das vorliegende Buch richtet sich an Berufsanfanger, Praktiker und Studenten der Informatik und der Ingenieurswissenschaften.

This book provides an account of the use of computational tactical metrics in improving sports analysis, in particular the use of Global Positioning System (GPS) data in soccer. As well as offering a practical perspective on collective behavioural analysis, it introduces the computational metrics available in the literature that allow readers to identify collective behaviour and patterns of play in team sports. These metrics only require the bio-dimensional geo-referencing information from GPS or video-tracking systems to provide qualitative and quantitative information about the tactical behaviour of players and the inter-relationships between teammates and their opponents. Exercises, experimental cases and algorithms enable readers to fully comprehend how to compute these metrics, as well as introducing them to the ultimate performance analysis tool, which is the basis to run them on. The script to compute the metrics is presented in Python. The book is a valuable resource for professional analysts as well students and researchers in the field of sports analysis wanting to optimise the use of GPS trackers in soccer.
