cztchoice / .bashrc
Created November 3, 2012 14:39 — forked from justintv/.bashrc
Display git branch in bash prompt
# If you work with git, you've probably had that nagging sensation of not knowing what branch you are on. Worry no longer!
#export PS1="\\w:\$(git branch 2>/dev/null | grep '^*' | colrm 1 2)\$ "
# This is easy
export PS1="\w\$(__git_ps1 '(%s)') \$ "
# This will change your prompt to display not only your working directory but also your current git branch, if you have one. Pretty nifty!
# ~/code/web:beta_directory$ git checkout master
# Switched to branch "master"

批判性思维

批判性思维香港的翻译为 申辩式思维 ，个人感觉这个才是好的翻译啊

是一个工具，这个工具是你对待信息的方式，即在你从某个地方（网上或者书上，还有其他人的语言里）看到一个消息，批判性思维就是用来判断这个消息中附带的观点是否是有错误或者误导性质的，从而决定你应不应该接受该消息中所附带的观点。

一般信息传播是带有一定的目的性的，而这个目的一般就是用来说服人们相信某种观点。

以此为依据信息就可以划分成两部分：

论题_结论，还有怎么得到这个结论的理由
