# 有关 Fiber 的解释: (按照数据流的方向分为两部分)

# 在 `主线程' 中使用 resume 方法来启动(或继续执行)一个 `纤程'.
# 1. 第一次调用 fiber.resume, 会启动一个纤程,
#    如果 resume 调用时提供了实参, 会作为代码块形参传入代码块.
# 2. 如果非第一次调用 fiber.resume, 即, `恢复' 一个纤程, 会做两件事:
#    - 从上次离开纤程的那个位置(调用 Fiber.yield 离开纤程的那个位置), 恢复纤程的执行.

RAILS_RELATIVE_URL_ROOT

Rails

By default RAILS_RELATIVE_URL_ROOT is used only for asset pipeline.

To namespace your rails routes you need to wrap run MyApp::Application with map in your config.ru:

map ENV['RAILS_RELATIVE_URL_ROOT'] || "/" do

Unfortunately, the Cisco AnyConnect client for Mac conflicts with Pow. And by "conflicts", I mean it causes a grey-screen-of-death kernel panic anytime you connect to the VPN and Pow is installed.

As an alternative, there is OpenConnect, a command-line client for Cisco's AnyConnect SSL VPN.

Here's how to get it set up on Mac OS X:

1. OpenConnect can be installed via homebrew:

    brew update
   

brew install openconnect

Dear Rubyists,

I just lost a contract because of my code in a Rails project.

The specific code in question is related to a "posting a comment" feature. Here are the details:

In this project, "posting a comment" does not simply entail inserting a row into the database. It involves a procedure to yes, insert a row, but also detect its language, check for spam, send emails, and "share" it to Twitter and Facebook. I believe this algorithm should be encapsulated. I do not believe it belongs in a controller or a model. I do not believe Active Record callbacks should be used.

The "senior developer", whom is the stake holder's right hand man, said this:

load 'rake/helper.rb'

desc "Set up the VM"
task :up do
  vm = VM.new
  vm.cli('up')
end

desc "Shutdown the VM"
task :graceful_down do
