（淡入一群身著制服，表情嚴肅的軍官。）

會議桌的主位上，一位資深高階將軍正在說話。

將軍：報告已經證實了，紐約市已經…被殭屍占領了。

上校：又來了？明明 28 天前才發生過一次殭屍入侵！

將軍：這些僵屍…不一樣。它們是… 哲學僵屍。

Extract Service Object

適合場景

複雜的 action
action 裡面牽涉到多個 model （如 e-commerce 的結帳，牽扯到訂單, 使用者, 明細的修改 )

Notes on Paul Irish's "Things I learned from the jQuery source" casts

I watched these videos on 2012/12/14. Today's jQuery version is 1.8.3. So there might be some differences from the original video. I've briefly noted some of the differences between what described in the video and the current stable release. Most code he desribed can be found easily in speed/jquery-basic.js (1.4.2).

A ZSH theme optimized for people who use:

Solarized
Git
Unicode-compatible fonts and terminals (I use iTerm2 + Menlo)

For Mac users, I highly recommend iTerm 2 + Solarized Dark

Patched ruby 1.9.3-p194 for 30% faster rails boot

What is?

This script installs a patched version of ruby 1.9.3-p194 with patches for boot-time performance improvements (#66 and #68), and runtime performance improvements (#83 and #84). It also includes the new backported GC from ruby-trunk.

Huge thanks to funny-falcon for the performance patches.
