RinRuby: Accessing the R Interpreter from Pure Ruby
Full text linkRinRuby is a Ruby library that integrates the R interpreter in Ruby, making R's statistical routines and graphics available within Ruby. The library consists of a single Ruby script that is simple to install and does not require any special compilation or installation of R. Since the library is 100% pure Ruby, it works on a variety of operating systems, Ruby implementations, and versions of R. RinRuby's methods are simple, making for readable code. This paper describes RinRuby usage, provides comprehensive documentation, gives several examples, and discusses RinRuby's implementation. The latest version of RinRuby can be found at the project website: http://rinruby.ddahl.org/.
Ruby Roney
No full textRuby was the youngest of nine children. After her mother died in 1904, she arrived by ship from Sydney then drove by horse and buggy out to Delamere Downs Station. She had came to the Territory to live with her uncle and aunt Mr and Mrs Paddy and Mariah Cahill. She moved with the Cahill family to Oenpelli helped with station cooking. During the five years in the bush, the teenager met John (Jack) Roney. They married in Sydney returned to the Territory to manage the Government Experimental Farm at the Daly River from 1916-1919. Having lost her first baby, she went to Sydney for their second child, Jack, born in 1919.
When the farm closed they went over to the Batchelor Experimental Farm until it finished. Then the Roneys, with their two sons, Terrence, born in the Territory in 1920 went on a holiday travelled south by ship for several months. They returned to live at Humpty Doo and in 1923 their daughter Monica was born at Darwin Hospital. After leaving Humpty Doo, the Roneys moved to Manbulloo and Willeroo Stations then Katherine. Her husband drank heavily and spent the income so Ruby made and sold bread, eggs, milk and meat from her goats and gave some away to other women in a similar situation to herself. Her husband died in Alice Springs, 13 December 1935. Ruby moved to Darwin and worked for the Commercial Bank.
When the war came Ruby, with her daughter Monica, were evacuated to Queensland by the American ship 'President Grant' two days before Christmas 1941. After the war was over they returned to live in Darwin.

Динамическое выделение типов в Ruby
Full text linkВьюгинов Николай Юрьевич Динамическое выделение типов в Ruby Старший преподаватель кафедры системного программирования Кириленко Яков Александрович Направление математика и механика, кафедра системного программирования Ruby - довольно популярный язык, он удобен и практичен. Обратной стороной такого удобства языка является сложность отладки и поиска ошибок в больших кодовых базах. Анализ кода на Ruby значительно усложняется засчёт некоторых возможностей языка. Даже в динамически типизированных языках программирования информация о типах переменных очень полезна, ведь она позволяет реализовать большее количество статических проверок. В работе описывается новый подход к генерации типовых аннотаций. Предлагается отслеживать непосредственные вызовы метода во время исполнения и генерировать на основе входных и выходных типов контракты, описывающие сигнатуру метода.

Syntax of Ruby language pays back when it comes to finding bugs in large codebases. Static analysis is hindered by specific capabilities of Ruby. Even in dynamically typed languages, type information is very useful, because of better type safety and more reliable checks. One may annotate the code with YARD (Ruby documentation tool) which also enables improved tooling such as code completion. This paper reports a new approach to type annotations generation. We trace direct method calls while the program is running, evaluate types of input and output variables and use this information to derive implicit type annotations. Sources cited: 21 Viuginov, N.Y.

Attitudes of gemstone distributors to value adding strategies of ruby production
Full text linkOver the centuries, gemstones have at times played a key role in the international trade. To date, they still play a significant role in economies of many countries, especially Thailand. Ruby, the red gemstone, one of the best known gemstones to ordinary people, is the focus of this study. Previous studies have shed the light on examinations of the characteristics and production methods of ruby. However, none has studied the attitudes of gemstone distributors toward several treatment strategies, which aiming to add value to ruby and maximize the return from the limited ruby supplies. The prime purpose of this study is to identify the value adding strategies deemed acceptable to gemstone distributors, by comparing their levels of satisfaction toward each treatment strategy. The findings reveal gemstone distributors accept that other methods in addition to normal cutting and polishing can also add value to rubies. Analyses of sample t-test and one-way repeated measures ANOVA suggest two treatment strategies of ruby production are deemed acceptable to gemstone distributors, and that the satisfaction levels of gemstone distributors toward each of the five treatment strategies are significantly different. Gemstone distributors consider heat treatment strategy as the most satisfactory strategy in adding value to rubies
Infrastructures of equality versus inequality
No full textWhile planning infrastructure at a large scale it can be easy to lost sight of its effects upon the individuals who actually use it, as well as its capacity to act as a multiplier of social equity. Joining up the dots between the data, density and development, Ricky Burdett explains how policy choices have emboldened infrastructure's social impact in Bogotá and London- and could do so elsewhere
