  4. 4. what is Ruby on Rails? used for ‘agile’ web development by allowing a developer to use the ‘CoC’ principle and RubyGems CoC – (Convention over Configuration) is a design principle that makes the implementation and coding of a project simpler by making the developer only specify the unconventional aspects of a app. For instance if a developer creates a class in the code the DB table will be named the same by default and all calls to that class will automatically reference that table RubyGem – a system for managing Ruby Software libraries. These libraries allow a developer to quickly add components like forms or member management without having to worry about dependences to other libraries since they are built to run as a independent package. A presentation by
  5. 5. what does it all mean? tell me more about Ruby •  an object-oriented programming inspired by Perl that was created in the mid-1990s and was initially developed and designed by Yukihiro quot;Matzquot; Matsumoto. •  created with the goal of making the programmer do less work. •  very flexible programming language •  features dynamic typing. •  built in garbage collector, this is used to keep from leaking memory. •  can load libraries dynamically based on need •  highly portable: developed mostly on GNU/Linux, but works on many types of UNIX, Mac OS X, Windows 95/98/Me/NT/2000/XP, DOS, BeOS, OS/2, etc. •  currently on build 1.8.7 A presentation by
  6. 6. what does it all mean? tell me more about Rails •  it was extracted by David Hansson from his work on Basecamp •  a programmer can use something called ‘scaffolding’ which automatically generates basic pieces of code necessary for the ‘logistics’ (deleting, adding, reading) of a site. •  built to use JS libraries out of the box so it is very behavior rich on the front end. •  does a great job of separating the MVC, which allows a developer to make ‘Web 2.0’ based apps that easily connects to the Server and DB, then packages the DB Row info into an object on the View •  works with •  Server - Apache, lighttpd, or nginx proxying to Mongrel •  Database - MySQL, PostgreSQL, SQLite, Oracle, SQL Server, DB2 etc. A presentation by
  7. 7. what does it all mean? what are the drawbacks of using it? •  still new so things like security holes are being found all the time •  setting up the Server to run RoR can be very challenging •  since so many things are done automatically out of the box - creation of DB tables, adding, modifying, deleting info in the tables - programmers can get lazy and the app can become hard to scale (see Twitter) •  can be hard to find good programmers •  most programmers need to learn 2 new technologies, Ruby and Rails A presentation by
  8. 8. what does it all mean? when should I use it? •  when creating a web app from scratch and need many of the components found in modern Web 2.0 offerings. RoR gives you these out of the box. •  when a web site is being driven by information from a Database. •  have a visual rich site, since RoR does a good job separating the MVC changes can be made data- handling without effecting the UI. •  you have an aggressive timeframe for launching a product A presentation by
