油烟机自动清洗功能好用吗？
当时安装的人说到costco买409号清洗液然后自动清洗就可以了，大家有用过的吗？
什么是409号，我没找到，或者用什么别的可代替？

最近在申请postdoc的职位，对方教授要推荐信。但是对方说是否给postdoc的位置取决
于6月的funding，但是看似机会还是挺大的。有如下几个问题想问问大家
第一、Postdoc的推荐信大家都是怎么写的?是自己写好让教授们签字然后给对方发过去
？还是一般都是教授们自己写，然后亲自给对方发过去？
第二、这推荐信是否要早点准备起来？（担心万一推荐信开了，结果funding没下来，
等日后再请这些教授开，他们会不会有意见？）

请问有兄弟姐妹转身份的时候如果要求补材料的话是要求材料邮寄过去还是传真的呀？
马上开学了，但是uscis发邮件给我说mail notice给我要我补材料，还没收到notice呢

其实问题是为什么goog在yahoo上只有24个数据？
from pandas.io.data import DataReader
from datetime import datetime
goog=DataReader("GOOG", 'yahoo', datetime(2000,1,1), datetime(2014, 4,30))
In [52]:
len(goog['Adj Close'])

一般都是教授自己写的。你需要做的是找好要推荐你的教授，确定他们会给你写
推荐信。然后就看对方教授的习惯了，有的教授习惯自己联系要推荐信，有的需要
你找推荐你的教授，直接问对方教授就清楚了。
对方教授不是要推荐信了？你还考虑啥早点不早点准备。推荐信写好后，以后再要就是
改改名字，发封email而已。如果打算给你写推荐信的教授都清楚不可能就写一封。
对于没有拿到offer，没有啥机会大不大的，继续找。
