R is a programming language that has been gaining popularity in the domains such as machine learning and artificial intelligence over the recent years. It has been praised for its simplicity and elasticity, and its creators were even assigned a rockstar status.

In this pamphlet, the author claims that this "blazing new technology" is actually a step backwards in the development of the domains that it tries to tackle, and the better means of expression, or better tools for doing the job, were available at least since the 70's, and that recently they are only getting better.

The pamphlet explores and expresses various computational intelligence methods using Guile, a very pleasant implementation of the Scheme programming language.

Computer Science is a dynamic and interdisciplinary field that encompasses the study of algorithms, data structures, programming languages, and computational theory, with applications spanning across virtually all domains of modern life. For beginners, the journey into computer science involves building a solid foundation in these fundamental concepts, which are essential for understanding how computers process information and solve problems. This paper introduces key concepts and tools that form the core of computer science, starting with an overview of computational thinking, problem-solving, and programming. It covers the basic principles of algorithms, logic, and data structures, providing insights into how data is organized and manipulated. Programming languages such as Python, Java, and C++ are introduced as vehicles for teaching programming skills and logical reasoning, alongside basic software development practices. The study of computer science for beginners also includes an exploration of key areas such as computer hardware, operating systems, databases, and networks. Emphasis is placed on developing practical coding skills and understanding the real-world applications of computer science, from web development to artificial intelligence. The paper concludes with a discussion of the importance of computational literacy and the wide-ranging career opportunities available in the technology sector.

There’s a lot of outdated information on the Web that leads new PHP users astray, propagating bad practices and insecure code. PHP: The Right Way is an easy-to-read, quick reference for PHP popular coding standards, links to authoritative tutorials around the Web and what the contributors consider to be best practices at the present time.

There is no canonical way to use PHP. The website aims to introduce new PHP developers to some topics which they may not discover until it is too late, and aims to give seasoned pros some fresh ideas on those topics they’ve been doing for years without ever reconsidering. This ebook will also not tell you which tools to use, but instead offer suggestions for multiple options, when possible explaining the differences in approach and use-case.

It is a living document and will continue to be updated with more helpful information and examples as they become available.

This book is on sale at Leanpub. 100% of the authors' royalties are going directly to the Electronic Frontier Foundation.

This open access State-of-the-Art Survey presents the main recent scientific outcomes in the area of reversible computation, focusing on those that have emerged during COST Action IC1405 "Reversible Computation - Extending Horizons of Computing", a European research network that operated from May 2015 to April 2019. Reversible computation is a new paradigm that extends the traditional forwards-only mode of computation with the ability to execute in reverse, so that computation can run backwards as easily and naturally as forwards. It aims to deliver novel computing devices and software, and to enhance existing systems by equipping them with reversibility. There are many potential applications of reversible computation, including languages and software tools for reliable and recovery-oriented distributed systems and revolutionary reversible logic gates and circuits, but they can only be realized and have lasting effect if conceptual and firm theoretical foundations are established first.

A variety of programming models relevant to scientists explained, with an emphasis on how programming constructs map to parts of the computer.What makes computer programs fast or slow? To answer this question, we have to get behind the abstractions of programming languages and look at how a computer really works. This book examines and explains a variety of scientific programming models (programming models relevant to scientists) with an emphasis on how programming constructs map to different parts of the computer's architecture. Two themes emerge: program speed and program modularity. Throughout this book, the premise is to "get under the hood," and the discussion is tied to specific programs. The book digs into linkers, compilers, operating systems, and computer architecture to understand how the different parts of the computer interact with programs. It begins with a review of C/C++ and explanations of how libraries, linkers, and Makefiles work. Programming models covered include Pthreads, OpenMP, MPI, TCP/IP, and CUDA.The emphasis on how computers work leads the reader into computer architecture and occasionally into the operating system kernel. The operating system studied is Linux, the preferred platform for scientific computing. Linux is also open source, which allows users to peer into its inner workings. A brief appendix provides a useful table of machines used to time programs. The book's website (https://github.com/divakarvi/bk-spca) has all the programs described in the book as well as a link to the html text.
