NYT: Tax Plan Shifts Trillions From U.S. Coffers to Richest Families
WASHINGTON — President Trump’s proposal to slash individual and business

a multitrillion-dollar shift from federal coffers to America’s richest
families and their heirs, setting up a politically fraught battle over how

车今天终于拿回来了。算是总结，感谢版上各位热心朋友的帮助
问题 --车开出20min 开始冒黑烟，有异味。朋友说车开着非常rough，加速困难，可能
上不了高速。行驶过程中，我发现车rpm达到4000，速度却是35mph，engine或者是motor声音很
大。
Triple A 诊断3天后结果如下：
@ 可以上高速，triple a 叫2个不同的人驾驶free way，65mph没问题。。
之前出现冒烟原因：
朋友开车手刹没有松开，可能是磨损刹车造成的；
@ 高rpm （4000），低速度（35mph）
朋友没有挂对档。我的taurus有两个D 档，一个是正常的drive，另外一个是下坡时
候专用的（可能相当于别的车的2档）。这也是他们觉得车rough，狠劲踩油门车速才勉强上去的
原因。
今天把车开回来的时候特意看了一下，转速1500， speed 30mph，车的噪音也比之前小
很多---当然是在挂档正确的前提下 |

500g unbleached flour
1 1/2 tsp salt
200g pitted prunes, roughly chopped
200g bittersweet chocolate, roughly chopped
2 tbsp unsalted butter, softened

先将酵母溶入100ml的水中，静置五分钟。
将面粉和盐混合均匀，中间挖一个洞，倒入溶解好的酵母水。再加上剩下的250ml的水。
揉好面团，面团这是会很湿润，但是没关系，因为之后，我们还要加入其它材料。
此时进行第一次发酵，发酵到两倍大。
拍下膨胀的面团，静置10分钟。
将剩下的材料揉入面团里。
将模具刷油，将面团整成长的loaf状，然后放入模具发酵。第二次发酵到面团高出模具

My portfolio volatility is roughly the same as S&P 500.
The reason for underperformance:

most part of the year.
2) My 50% cash position, including 100% cash in 401k.
In 2011, I will show off monthly instead of weekly and will set

So each word appears in roughly 2^42 * 8 / 2^14 = 2^31 messages.
So in the index table, each word has roughly 2^31 corresponding records and

during that 5 years, so add another 10% discount to that. maybe 9% prob to
make 1M, 0.9% prob to make 10M, 0.1% prob to make 100M. but those high

1. go to a start up, 5 year horizon. roughly say you have 90% prob to make
only the salary (say 100k) then loose your job and this could happen anytime
during that 5 years, so add another 10% discount to that. maybe 9% prob to
make 1M, 0.9% prob to make 10M, 0.1% prob to make 100M. but those high
payouts are likely to be in restricted company shares so I d put a 10%
discount on them.
so we have 0.9*100k*0.9*5+0.09*1000k*0.9+0.009*10000k*0.9+0.001*100000k*0.9

servers for the size of their sets of data, call this n, so that it knows to
look for the k = n/2 largest element.
The master then selects a random server and queries it for a random element
from the elements on that server. The master broadcasts this element to
each server, and each server partitions its elements into those la... 阅读全帖 |

发帖数: 884 | 48 If you do not want to do the actual calculation, just think that the total
financial burden for owning the house is roughly the monthly payment to the
bank.
Because at the current loan rate, what you save from tax deduction ~30% * (
interest+real estate tax) will roughly be the same as what you need to pay
the real estate tax. |
