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。

Patched ruby 1.9.3-p0 for 30% faster rails boot

What is?

This script installs a patched version of ruby 1.9.3-p0 with patches to make ruby-debug work again (#47) and boot-time performance improvements (#66 and #68), and runtime performance improvements (#83 and #84).

Huge thanks to funny-falcon for the performance patches.

Instrument Anything in Rails 3

With Rails 3.0 released a few weeks ago I've migrated a few apps and I'm constantly finding useful new improvements. One such improvement is the ability to log anything in the same way that Rails internally logs ActiveRecord and ActionView. By default Rails 3 logs look slightly spiffier than those produced by Rails 2.3: (notice the second line has been cleaned up)
