Perl 6 Deep Dive. Data manipulation, concurrency, functional programming, and more

Andrew Shitov

Perl is a family of high-level, general-purpose, interpreted, dynamic programming languages consisting of Perl 5 and Perl 6. Perl 6 helps developers write concise and declarative code that is easy to maintain. This book is an end-to-end guide that will help non-Perl developers get to grips with the language and use it to solve real-world problems. Beginning with a brief introduction to Perl 6, the first module in the book will teach you how to write and execute basic programs. The second module delves into language constructs, where you will learn about the built-in data types, variables, operators, modules, subroutines, and so on available in Perl 6. Here the book also delves deeply into data manipulation (for example, strings and text files) and you will learn how to create safe and correct Perl 6 modules. You will learn to create software in Perl by following the Object Oriented Paradigm. The final module explains in detail the incredible concurrency support provided by Perl 6. Here you will also learn about regexes, functional programming, and reactive programming in Perl 6. By the end of the book, with the help of a number of examples that you can follow and immediately run, modify, and use in practice, you will be fully conversant with the benefits of Perl 6.

PHP 7. Algorytmy i struktury danych

Mizanur Rahman

Algorytmy i struktury danych leżą u podstaw programowania. Zrozumienie zasad rządzących tymi zagadnieniami jest koniecznym warunkiem opracowania prawidłowej i efektywnej aplikacji. Niestety, wielu programistów uznaje tę tematykę za zbyt złożoną czy zbyt banalną i nie poświęca jej wystarczającej uwagi. Takie podejście często się mści: modne narzędzia, frameworki czy technologie deweloperskie nie zapewnią sukcesu, jeśli projektant nie przemyśli zastosowanych algorytmów i struktur danych. Z tego obowiązku nie zwalniają nawet narzędzia wbudowane w język PHP! Jeśli chcesz biegle posługiwać się algorytmami, wziąłeś do ręki właściwą książkę! Przedstawiono tu podstawy implementacji algorytmów i struktur danych w PHP, dzięki czemu poznasz rodzaje struktur i powody, dla których warto je wybierać, a także dowiesz się, gdzie i kiedy należy stosować poszczególne algorytmy. Znajdziesz tu dużo praktycznych przykładów, które uzupełniono rysunkami i wyczerpującym komentarzem. Przystępne i zrozumiałe wyjaśnienia ułatwią Ci szybkie przyswojenie prezentowanych koncepcji, nawet tak złożonych, jak programowanie dynamiczne, algorytmy zachłanne, algorytmy z nawrotami czy funkcyjne struktury danych. Najważniejsze zagadnienia: podstawy analizy algorytmów i struktur danych, tablice, listy i drzewa, stosy, kolejki i algorytmy rekurencyjne, sortowanie, wyszukiwanie, sterty i kopce, wsparcie ze strony PHP, w tym biblioteki PECL i Tarsana. Algorytmy: poznaj, zrozum, stosuj! Mizanur Rahman od 14 lat rozwija aplikacje w PHP. Jest znawcą Laravela, CodeIgnitera, Symfony, JavaScriptu, C, C++, Javy, Node.js, Socket.io i React.js. Jest właścicielem dwóch startupów technologicznych. Jest osobą niezwykle zaangażowaną w życie kilku społeczności programistycznych, takich jak PHPXperts, Agile Bangladesh czy Project Euler. Regularnie wygłasza referaty na różnych konferencjach i seminariach technologicznych. Wraz z żoną Nishą i dwoma synami, Adiyanem i Mikhaelem, mieszka w Dhace w Bangladeszu. Jego pasją są podróże po świecie.
