Learn Shell is a free interactive Shell tutorial for people who want to learn Shell. It offers chapters covering basics such as variables, arrays, operators, decision making, loops and functions, plus advanced topics including special variables and regular expressions. The site states it is intended for everyone who wishes to learn programming with Unix/Linux shell interpreters.
PHP: The Right Way is an easy-to-read, quick reference for PHP best practices, accepted coding standards, and links to authoritative PHP tutorials. It is a living document translated into many languages and also available in PDF, EPUB and MOBI formats. It recommends starting with the current stable version, PHP 8.5.
Big-O Cheatsheet is a webpage presenting space and time Big-O complexities of common computer science algorithms. It includes a Big-O complexity chart, common data structure operations with average and worst case time complexity and space complexity, and array sorting algorithms with best, average and worst case time complexity. A downloadable PDF version is offered.
The C++ Core Guidelines are a set of guidelines, rules, and best practices about coding in C++. Bjarne Stroustrup and Herb Sutter edit the living document, which is under continuous improvement and licensed under an MIT-style license. The document states that its sets of rules have not been completely checked for completeness, consistency, or enforceability.
8bitWorkshop is a browser-based IDE for writing 8-bit game code, letting users write code and see it run instantly while learning how classic game hardware worked. It covers game consoles and arcade games, and the site offers books on topics such as the Atari 2600, NES and Commodore 64.
OverTheWire is a community offering wargames intended to help people learn and practice security concepts through games. Its suggested order begins with Bandit for Unix/Linux basics, followed by a choice among Natas for web security, Krypton for cryptography or Leviathan for reverse engineering, then binary exploitation games. Each shell game uses its own SSH port.
A curated list of resources for learning PHP, covering tutorials, books, online courses and reference material. Topics include the LAMP stack, HTML, CSS, JavaScript, protocols, local development environments, tools, frameworks, object-oriented programming, design patterns, databases, testing, security and architecture.
