#7 楼 @zj0713001 对于我这样入门的人来说，还是得先从母语开始，英文碰到不懂得容易停顿和打消积极性。理解一下英语不好的新手。 --忘了说，收到了。还加送一本。

#1 楼 @zj0713001 是中文版本？还是英文的？ 中文的要一份了。[email protected]

只想说，都是大牛呀。我周围 5-8 的占 85% 多。看来档次比较低。也在帝都。Java php ruby android 都有。。果然很苦逼呀。当然北邮、北航的还是过万的好多。但也不是所有人都过

#25 楼 @ichord 看看这个 http://www.apple.com/hk/en/support/macbookair-flashdrive/

商业项目我都求过源代码 汗: 待遇不错

经常去点的人 +1 就是很多打不开 +1

我竟然没有在，这个需要扯下蛋

躺着也中枪呀，刚刚申请更换

表示直接不敢点开

断入手了 说是 3 天送到

报名加入

多段安装了 很不错 mysql 哈哈 不会芒果的人

改改标题吧 就是开源项目的代码 还以为开源了呢

#9 楼 @seveniruby 我的意见还是再检查一次版本号 我的开始就是版本的问题 包括 ruby 用的 1.92

8 错

可以增加一个不喜欢的按钮吗

#7 楼 @huacnlee 貌似没有私信功能，我给你帐号和密码你看看 没有操作 mongoid.yml 只是默认然后直接 rails s 了

不能贴图了，只能放代码、@huacnlee
