A Look at the Future by Looking at the Past
The UNIX has survived for almost 5 decades and will survive for another 5 decades or more. What if we could build Gems that could evolve and still provide useful unit of functionality for decades to come? The ‘What’ is found in the tests, the ‘How’ is found in the production code and the ‘Why’ is not found in any form of code. The ‘Why’ is the design decisions that developers make and it evolves over time. Some of the ‘why’s can be found in the form of comments, blog posts and as discussion threads between the developers on forums. How can we minimize the time spent on ‘Why?’. Can developers become more productive by developing Micro Gems that follow the UNIX philosophy? Read more about this topic : Micro Gem : A Look at the Future by Looking at the Past
Using presenters and decorators to clean up your templates in Ruby on Rails (VIDEO)
When developing a web application, templates usually need to implement some logic, especially conditionals.
