比较网站开发的语言排行才有意义，ruby, python,perl, php, java 等等 执行效率上应该是 py, java 更胜一筹，ruby 的优势貌似就是“没得商量，你得照我画的路线走”，还有他奇怪的语言特性，除了 Rails 它还会是什么？ 我感觉对于 py，不管是桌面开发还是网络应用甚至数值计算，将来都有用武之地。php 就算了，很混乱的一个东西。

git 钩子 (HOoook...) 的作用

#8 楼 @DoIT 可以了，总算勉强能用了，谢谢你。不过好像必须要装 smart-tab（我之前以为是他在搞鬼，所以就把它卸了，我的代码里也注释掉了）。 而且它的 wiki 里写的很误导人，必须要加入一段 C-like languages 里面的代码才能用，传送门，http://www.emacswiki.org/SmartTabs#toc6

再次感谢@DoIT 的路见不平拔刀相助！！

#4 楼 晕，缩进了也没语法高亮啊

我按了 C-h k TAB，下面是触发的函数 ruby-indent-line is an interactive compiled Lisp function in `ruby-mode.el'.

(ruby-indent-line &optional FLAG)

Correct the indentation of the current ruby line.

[back] 打开了 ruby-mode.el，找到了这个函数

(defun ruby-indent-line (&optional flag) "Correct the indentation of the current ruby line." (interactive) (ruby-indent-to (ruby-calculate-indent)))

不知道怎么解决，寝室里的电脑也是这样，ruby-mode 的 TAB 一样用不了，你们的可以用吗

#2 楼 @DoIT 它确实是一个 function，然后呢？

don't 沉了。。

compass 的 sass 貌似早就悄悄换成了 scss 了，当然 config.rb 里面可以设置成 sass。。擦，坟贴。。

就推荐一个 ide-skel 功能是可视化选择打开的文件，适合任何项目，C+F10 可以立刻打开/关闭。 Emacs 配置是一门艺术啊，建议把常用的功能都挂到快捷键上，比装好多 mode 受用多了，像我的：F5 杀掉当前 buffer，C+F5 是立刻开一个 shell buffer，git 用户可以 C+F6 开启 magit-status

元芳，你怎么看这件事？

#5 楼 @help5305fff 恩，只是举个栗子。。

#4 楼 @Rei ，多谢多谢，搞明白了，用不到 count_cache

#1 楼 @fresh_fish #2 楼 @Rei ，谢谢，如果想靠这个参数对 user 做个排序的话，请问，有没有什么好的方法 User.order("???") 这个？??填什么好？

我又试了一下，换成了 mysql 就没问题了，我估计跟 database.yml 这个文件设置有关，我之前用的 sqlite 配置是这样的

adapter: sqlite3 pool: 5 timeout: 5000 database: db/sudo.sqlite3

是不是少了什么参数，还是顺序有要求？

@iBachue ，你是说 scheme.rb 文件吗

我自己想到一个折衷的方法，每次 migration 脚本执行完后，再把他移到其他目录。。。

#7 楼 @bigfang +1，emacs 24
