发帖数: 824 | 1 You should understand the relationship between exposure time and focal
length. For shorter focal length, the safe exposure time (for minimize the
hand motion blur) is longer. A common rule of thumb for estimating how fast
the exposure needs to be for a given focal length is the one over focal
length rule, but that is for full frame camera or 35mm format sensor.
For cell phone camera, the sensor is much smaller. For iphone4s/5, it is
about 3.4mm x 4.6mm. The crop factor should be 7.8 (36mm/4.6mm)... 阅读全帖 |

The Centers for Disease Control and Prevention wants to study autism as a
possible clinical outcome of immunization, as part of its newly adopted 5-
year research agenda for vaccine safety, the agency said on its website.
The CDC will also study mitochondrial dysfunction and the potential risk for
post-vaccine "neurological deterioration," and convene an expert panel on

你要做到两点：
1。 风险控制。
2。 选对的股票。
第一点容易理解但很容易被忽视，但是第一点比第二点更重要！
第二点比较难，但是你可以慢慢学。只要愿意学，你迟早都会的。
我想告诉大家我怎么做到第一点。
用EXCEL纪录自己每天的舱位。如果你的账户全是股票，那很简单。把你所有的舱位加
起来，是你的毛资产。加上你的现金或马金，是你的净资产。
用你的毛资产除以你的净资产，是你的exposure。比如你有6万古飘，马金一万，净资
产5万。你的exposure是120%。
如果你有SHORT舱位的话，把它也加上。记住它不可以用来抵消long舱位。比如你有7万
古飘，一万SHORT, 马金一万，净资产5万。你的exposure是160%。
如果你有粮票的话，从净资产和毛资产中扣除。当你已经没有这笔钱。比如你有7万古
飘，一万两票，一万SHORT, 马金一万，净资产6万。你的exposure是160%。
设定一个上限。当这个上限达到的时候你无论如何不能够做增加exposure的任何操作。
只能够减。如果你有SHORT的话，上限可以适当放宽。
我个人的上限是130 |

first choice...但是你可能要花一两个小时熟悉它
bulman credibility...用1还是100关键看题目怎么问， 如果这个credibility下一步
是给了exposure, 那么就用100, 因为这个credibility是针对exposure的, 如果下一步
是同样的exposure, 给了不同的years, 就用1..
总之, credibility就是你之前理论上的估算总会有偏差, 所以要结合实际的历史数据
给一个credibility rate, 再apply到将来的数据上，如果将来的数据是关于exposure
的, 那么就要用exposure相关的credibility rate. 反之亦然:) |

1. I live on the West Coast. Am I in danger?
No. Absolutely not.
You won’t even notice except that everyone will keep talking about it for
ages, and it’ll take us even longer to get off coal and oil and natural gas
because people will be afraid of nuclear power again. Go outside, get some
sunshine (or rain, depending), be grateful for the fact that your city isn
