Ciągłe dostarczanie oprogramowania w języku Java. Najlepsze narzędzia i praktyki wdrażania kodu
Daniel Bryant, Abraham Marín-Pérez
W ciągu ostatnich lat radykalnie zmieniły się wymagania i oczekiwania biznesowe wobec oprogramowania. Kluczowymi wartościami są innowacyjność, szybkość i czas wejścia na rynek. Do spełnienia tych wymagań konieczne okazały się nowe architektury i modele tworzenia kodu. Metodyka ciągłego dostarczania, zwanego też CD, polega na tworzeniu w krótkich cyklach wartościowych i solidnych produktów. Funkcjonalności są dodawane w małych krokach, a oprogramowanie można wydawać niezawodnie w dowolnej chwili. To sprawia, że można też szybko otrzymywać informacje zwrotne. Jednak taki sposób pracy wymaga odpowiednich ram organizacyjnych, a zespół projektowy musi przyswoić nieco inny od tradycyjnego styl pracy. Ta książka jest praktycznym przewodnikiem, dzięki któremu programiści Javy opanują techniki potrzebne do pomyślnego zastosowania metody ciągłego dostarczania. Opisano tu najlepsze zasady budowy architektury oprogramowania, automatycznej kontroli jakości, pakowania aplikacji i wdrażania ich w różnych środowiskach produkcyjnych. Szczególną uwagę poświęcono testowaniu oprogramowania: przedstawiono całą gamę metodyk testowania, opisano ich zastosowanie i znaczenie w cyklu życia aplikacji. Ciekawym elementem książki są informacje o złych praktykach i antywzorcach wraz ze wskazówkami dotyczącymi rozwiązywania tego rodzaju problemów. W tej książce między innymi: solidne podstawy ciągłego dostarczania oprogramowania migracja do ciągłego dostarczania oprogramowania narzędzia: Jenkins, PMD i FindSecBugs zasady testowania funkcjonalności i jakości oprogramowania techniki obserwacji aplikacji w środowisku produkcyjnym Java i CD: tak zdobędziesz prawdziwą przewagę!

Data-structures and algorithms often cross your path when you compress files, compile programs, access databases, or simply use your favourite text editor. Understanding and implementing them can be daunting. Curious learners and industrial developers can find these complex, especially if they focus on the detailed implementation of these data structures.Clojure is a highly pragmatic and expressive language with efficient and easy data manipulation capabilities. As such, it is great for implementing these algorithms. By abstracting away a great share of the unnecessary complexity resulting from implementation, Clojure and its contrib libraries will help you address various algorithmic challenges, making your data exploration both profitable and enjoyable.Through 25 recipes, you'll explore advanced algorithms and data-structures, well served by a sound Clojure implementation.This book opens with an exploration of alternative uses of the array data-structure, covering LZ77 compression, drawing fractals using Pascal's triangles, simulating a multi-threaded program execution, and implementing a call-stack winding and un-winding operations.The book elaborates on linked lists, showing you how to construct doubly linked ones, speed up search times over the elements of such structures, use a linked-list as the foundation of a shift-reduce parser, and implement an immutable linked-list using skew binary numbers representation.After that, the tree data-structure is explored, focusing on building self-balancing Splay Trees, designing a B-Tree backing-up an efficient key-value data-store, constructing an undo capable Rope, and showing how Tries can make for an auto-completing facility.Next, some optimization and machine learning techniques are discussed, namely for building a co-occurrence-based recommendation engine, using branch-and-bound to optimize integral cost and profit problems, using Dijkstra's algorithm to determine optimal paths and summarizing texts using the LexRank algorithm.Particular attention is given to logic programming, you will learn to use this to discover interesting relations between social website data, by designing a simple type inferencer for a mini Java-like language, and by building a simple checkers game engine.Asynchronous programming will be addressed and you will design a concurrent web-crawler, an interactive HTML5 game, and an online taxi booking platform.Finally, you'll explore advanced cases for higher order functions in Clojure while implementing a recursive descent parser using efficient mutual resucrsion, devising a mini resusable firewall simulator thanks to Clojure 1.7 new tansducers feature or building a simple unification engine with the help of Continuation Passing Style.
