看了一下 README，简直就是 Rails 项目集成大全。保存慢慢消化

我还在琢磨怎么出北京然后回来～～～

复杂一点可以加上语义分析。就是在特定的环境下理解对话的含义。比如“头疼”在求医过程应该是医生或者科室，而朋友聊天也许就是个感叹

缺少个新手引导，点到首页以后不知道特点是什么，为什么要去注册。

我发现用 ActiveSuppor 的包能解决我的问题

module EtlPipline
  extend ActiveSupport::Concern
  attr_accessor :seg_name
end

说的是这个？ Using a mutex to protect critical data is sometimes not enough. Suppose you are in a critical section, but you need to wait for some particular resource. If your thread goes to sleep waiting for this resource, it is possible that no other thread will be able to release the resource because it cannot enter the critical section---the original process still has it locked. You need to be able to give up temporarily your exclusive use of the critical region and simultaneously tell people that you're waiting for a resource. When the resource becomes available, you need to be able to grab it and reobtain the lock on the critical region, all in one step. This is where condition variables come in. A condition variable is simply a semaphore that is associated with a resource and is used within the protection of a particular mutex. When you need a resource that's unavailable, you wait on a condition variable. That action releases the lock on the corresponding mutex. When some other thread signals that the resource is available, the original thread comes off the wait and simultaneously regains the lock on the critical region.

这个我怎么运行出错？ module:Pipline': undefined method `seg_column_name=' for Pipline:Module (NoMethodError)

在北京也能远程吗？

报名成功，不过发的卡券不能存到微信卡包，提示过期。

加油，我还在 activesupport 的模块里面徘徊

40+ 的程序员考虑吗？
