When using Rails by way of a shared Vagrant folder we need to edit one config file to ensure that the Rails server works properly.
After creating a new Rails application (but before starting the Rails server) the following file in a text editor:
config/environments/development.rb
Change the second last line in this file (line 53) from:
config.file_watcher = ActiveSupport::EventedFileUpdateChecker
| xcode-select --install | |
| gem install nokogiri |
Fibur is a library that allows concurrency during Ruby I/O operations without needing to make use of callback systems. Traditionally in Ruby, to achieve concurrency during blocking I/O operations, programmers would make use of Fibers and callbacks. Fibur eliminates the need for wrapping your I/O calls with Fibers and a callback. It allows you to write your blocking I/O calls the way you normally would, and still have concurrent execution during those I/O calls.
Say you have a method that fetches data from a network resource:
