Visual Studio Code What is Visual Studio Code? Any programme / software that we see or use, works on the code that runs in the background. Traditionally coding used to done in the traditional editors or even in the basic editors like notepad ! These editors used to provide basic support to the coders. Some of them, so were so basic that it was very difficult in writing basic English level programmes in them. As the time-went by, some programming languages needed specific framework and support for further coding and development in it, which was not possible using these editors. VI Editor, Sublime Text Editor and Visual Studio Code are one of the many kinds of editors that came into existence. The most prominent and which supports almost every coding language is VISUAL STUDIO CODE. Visual Studio Code features let user modify the editor as per the usage, which means, user is able to download the libraries from the internet and integrate it with the code as per his requirements. Visual Studio Code Definition and understanding it Visual Studio Code is a code editor in layman’s terms. To define it, Visual Studio Code is, “a free-editor which helps the programmer to write a code, helps in debugging and corrects the code using the intelli- sense method ”. In normal terms, it facilitates user to write the code in easy manner. Many people say that it is half of an IDE and an editor; but the decision is upto to the coders.

Rubabel: Wrapping Open Babel with Ruby Rob Smith1*, Ryan Williamson1, Dan Ventura1 and John T Prince2*
Smith et al. Journal of Cheminformatics 2013, 5:35 http://www.jcheminf.com/content/5/1/35 SOFTWARE Open Access Rubabel: wrapping open Babel with Ruby Rob Smith1*, Ryan Williamson1, Dan Ventura1 and John T Prince2* Abstract Background: The number and diversity of wrappers for chemoinformatic toolkits suggests the diverse needs of the chemoinformatic community. While existing chemoinformatics libraries provide a broad range of utilities, many chemoinformaticians find compiled language libraries intimidating, time-consuming, arcane, and verbose. Although high-level language wrappers have been implemented, more can be done to leverage the intuitiveness of object-orientation, the paradigms of high-level languages, and the extensibility of languages such as Ruby. We introduce Rubabel, an intuitive, object-oriented suite of functionality that substantially increases the accessibily of the tools in the Open Babel chemoinformatics library. Results: Rubabel requires fewer lines of code than any other actively developed wrapper, providing better object organization and navigation, and more intuitive object behavior than extant solutions. Moreover, Rubabel provides a convenient interface to the many extensions currently available in Ruby, greatly streamlining otherwise onerous tasks such as creating web applications that serve up Rubabel functionality. Conclusions: Rubabel is powerful, intuitive, concise, freely available, cross-platform, and easy to install. We expect it to be a platform of choice for new users, Ruby users, and some users of current solutions. Keywords: Chemoinformatics, Open Babel, Ruby Background tasks. Though it allows the user to access the functionality Despite the fact that chemoinformatics tools have been of the component libraries from one Python script, Cin- developed since the late 1990s [1], the field has yet to fony does not automatically manage underlying data types rally in support of a single library.

To Use a Binary Repository Manager When Developing with Rubygems
10 Reasons To Use A Binary Repository Manager When Developing With RubyGems White Paper Introduction Over the last several years software development has evolved from packages within your organization, whether developed in-house, focusing on in-house coding to making extensive usage of binary downloaded from RubyGems.org or downloaded from other components such as free open-source libraries and commercial 3rd party resources. This white paper describes how Artifactory libraries as well as proprietary libraries built addresses the above issues, substantially reducing development in-house. Already in a survey conducted back in 2010, 98% of and build time, while requiring very little effort from your organization. enterprise level companies reported that they use open source software1, and a typical software project today will be comprised of more assembled components than proprietary code. Companies developing with Ruby are no exception. Over 3 Billion gems have been downloaded from RubyGems.org since its inception in 20092. While there are many benefits to using RubyGems, there are still several challenges that it does not address. Some of these are: • Long and network intensive build processes • Offline access to packages and metadata • Security and access control for gems • Sharing internal and external gems • Binary version tracking to reproduce builds • Searching for gems based on different criteria • Stability and reliability of systems hosting gems • Customized handling of gems • Maintenance and monitoring of artifacts Artifactory is a Binary Repository Manager that manages all All rights reserved. 2015 © JFrog Ltd.
