B. Brodey and Todd Ramón Ochoa) This dissertation is a critical analysis and annotated translation, from Spanish into English, of the book Reglas de Congo: Palo Monte Mayombe, by the Cuban anthropologist, artist, and writer Lydia Cabrera (1899-1991). Cabrera’s text is a hybrid ethnographic book of religion, slave narratives (oral history), and folklore (songs, poetry) that she devoted to a group of Afro-Cubans known as “los Congos de Cuba,” descendants of the Africans who were brought to the Caribbean island of Cuba during the trans-Atlantic Ocean African slave trade from the former Kongo Kingdom, which occupied the present-day southwestern part of Congo-Kinshasa, Congo-Brazzaville, Cabinda, and northern Angola. The Kongo Kingdom had formal contact with Christianity through the Kingdom of Portugal as early as the 1490s.

  • Metaprogramming Ruby
    Prepared exclusively for Shohei Tanaka What Readers Are Saying About Metaprogramming Ruby Reading this book was like diving into a new world of thinking. I tried a mix of Java and JRuby metaprogramming on a recent project. Using Java alone would now feel like entering a sword fight carrying only a banana, when my opponent is wielding a one-meter-long Samurai blade. Sebastian Hennebrüder Java Consultant and Trainer, laliluna.de This Ruby book fills a gap between language reference manuals and programming cookbooks. Not only does it explain various meta- programming facilities, but it also shows a pragmatic way of making software smaller and better. There’s a caveat, though; when the new knowledge sinks in, programming in more mainstream languages will start feeling like a chore. Jurek Husakowski Software Designer, Philips Applied Technologies Before this book, I’d never found a clear organization and explanation of concepts like the Ruby object model, closures, DSLs definition, and eigenclasses all spiced with real-life examples taken from the gems we usually use every day. This book is definitely worth reading. Carlo Pecchia Software Engineer I’ve had a lot of trouble finding a good way to pick up these meta- programming techniques, and this book is bar none the best way to do it. Paolo Perrotta makes it painless to learn Ruby’s most complex secrets and use them in practical applications.

This repository contains the binaries, huge libraries and third party libraries that form the foundation of the execution of application. The repository has four prime packages – Java, nsis, python and ruby. Like the names suggest, each of these packages have the contents based on the language of code. In this analysis report, the prime focus is laid on the python and the ruby packages only. The prime purpose of the code base is to support the functionalities of the RCS with the required library functions, 3rd Party libraries and compiled binaries. Additionally there are some libraries, which help the developer to set up the development environment and the play-environment to run the RCS. We analyzed the code repository and dig-in for portions of the code, which seem interesting to us. Initially we went through the RCS admin and service manuals [1] to understand the features of the RCS and develop a high level picture of the application.

  • Reference Coupling: an Exploration of Inter-Project Technical Dependencies and Their Characteristics Within Large Software Ecosystems
    Reference Coupling: An Exploration of Inter-project Technical Dependencies and their Characteristics within Large Software Ecosystems Kelly Blincoea,∗, Francis Harrisonb, Navpreet Kaurb, Daniela Damianb aUniversity of Auckland, New Zealand bUniversity of Victoria, BC, Canada Abstract Context: Software projects often depend on other projects or are developed in tandem with other projects. Within such software ecosystems, knowledge of cross-project technical dependencies is important for 1) practitioners under- standing of the impact of their code change and coordination needs within the ecosystem and 2) researchers in exploring properties of software ecosystems based on these technical dependencies. However, identifying technical depen- dencies at the ecosystem level can be challenging. Objective: In this paper, we describe Reference Coupling, a new method that uses solely the information in developers online interactions to detect technical dependencies between projects. The method establishes dependencies through user-specified cross-references between projects. We then use the output of this method to explore the properties of large software ecosystems. Method: We validate our method on two datasets | one from open-source projects hosted on GitHub and one commercial dataset of IBM projects. We manually analyze the identified dependencies, categorize them, and compare them to dependencies specified by the development team. We examine the types of projects involved in the identified ecosystems, the structure of the iden- ∗Corresponding author Email addresses: [email protected] (Kelly Blincoe), [email protected] (Francis Harrison), [email protected] (Navpreet Kaur), [email protected] (Daniela Damian) Preprint submitted to Elsevier February 2, 2019 tified ecosystems, and how the ecosystems structure compares with the social behaviour of project contributors and owners.
