Rails 開發注意要點

About Ruby Syntax

• 編輯器設定 soft tab (space=2)，以 2 格空白符號做為程式內縮距離（不分語言）。
• 函式如果只有一個參數，就不強制打()
• 函式如果有二個以上的參數，通通都要有 ()
  • (避免發生奇怪的paser bug跟保持專案一致性)
• 字串限定用雙引號包覆
• 善用 "#{str1} #{str3} " 等字串改寫技巧取代不需要的字串加法。

Deploying Rails to Linode

Installing Ruby Enterprise Edition, Apache, MySQL, and Passenger for deploying Rails 3.0 applications.

Get a Linode, and set it up with Ubuntu 10.04 LTS so that you have till April 2013 to get updates. Once the Linode is formatted, boot it and continue on.

Set up an 'A' record in your DNS, pointing to the IP of your Linode. I'm using demo.napcs.com here.

Initial setup
