Speaking UNIX, Part 14: Manage Ruby and gems with RVM Although Internet Relay Chat, forums, and revision control tools such as Git and Github make distributed development a snap, reproducing another developer's environment can be quite maddening. Propping up an existing body of code on a new development machine requires matching with at least some and potentially all of the original coder's stack, or many prerequisite software components that power the application. A stack may demand a type of operating system (say, UNIX®, Linux®, Mac OS, or Windows®); a specific operating system version (Ubuntu 10 or 11? Mac OS X 10.6 Snow Leopard or 10.7 Lion?); a minimum collection of built-in and supplemental system libraries and header files; a supporting cast of daemons and services (MySQL or PostgreSQL?); and, of course, any number of language-specific resources, from the compiler to a specific patch level of supporting open source code.

Ruboto: Ruby on Android Introduction Most of the interesting work in software development today occurs at one of the two extremes: huge cloud servers and tiny mobile devices. These domains solve significantly different problems, and, correspondingly, have different tool support. Server development often uses scripting languages to tie together different components and accomplish sophisticated automated tasks, while mobile development focuses on the particular capabilities and needs of a particular device and user. However, these two extremes share a common language: Java™. Whether Android or the Spring framework, many of the most popular technologies today have adopted a language that's widely understood and supported around the world.

Programmation Ruby/Types standards Un livre de Wikilivres. << Retour au sommaire Nous allons voir ici tous les types que nous pouvons considérer comme "standards", dans le sens où nous les retrouvons dans la plupart des langages, et que ceux-ci sont directement intégrés à l'interpréteur (built-in). Néanmoins il ne faut pas perdre de vue qu'il s'agit en réalité d'objets. Pour rappel les méthodes dont le nom se termine par ! sont non pures : elles modifient l'objet.

Getting Started with Nokogiri | Engine Yard Ruby on Rails Blog We’re decided to mix up the Engine Yard blog a little and invite some community members to contribute guest posts. This one (our first!) is from Aaron Patterson — a long-time member of the Ruby community, and the creator of Nokogiri. He hacks with the developers of Seattle.rb, and travels the world to speak about Nokogiri and other Ruby topics at industry conferences and events. Nokogiri is a library for dealing with XML and HTML documents. I wrote Nokogiri along with my (more attractive) partner in crime, Mike Dalessio.

The chef-client uses Ruby as its reference language for creating cookbooks and defining recipes, with an extended DSL (domain-specific language) that is used for specific resources. Enough resources are available to support the most common infrastructure automation scenarios natively within Chef; however, this DSL can also be extended when additional resources and capabilities are required.
