看了看注意事项,条条框框不少哦。
首先是DOUBLE以后,最多也每件商品减2块。所以用1.5的胖子,只减1.5+0.5=2
用MFQ的话,一次最多DOUBLE 3张一样的。多的话,只是FACE VALUE。
Q上写了DO NOT DOUBLE的,不能DOUBLE。我刚才看了看SMART SOURCE的胖子,上面写了
DO NOT DOUBLE。
等等等,见下面。
•We double manufacturer’s coupons up to face value of $0.99; with
total amount not to exceed $2.00 or entire retail of item; whichever is less.
•We double up to three identical items with manufacturer coupon;
additional coupons for like item will be honored at face value. Like items

来自主题: PennySaver版 - 今天去实验Ralphs 的super double了
买了两单,
第一单一个0.88的mist加一些别的东西,小二看胖子overage,就手动输入0.88,没有
double(我猜是手动所以没double)
第二单另一个小二,一个0.88的mist+0.88的green giant 两盒,1off2的 green giant
double了,只是1+0.76,0.88的只减了1.00没double(这次我又猜是因为胖子overage
了所以没double)
这说明确实是double up to 1.00的,我看到那个policy最后写的是limit5,但是开前
半部分却写着limit 1 double coupon per house。
问题就出现了:到底是1单double 5个呢,还是一单就只double1个,limit 5个coupon
,可是这样的话,为什么要限制coupon数呢?
等待小白鼠或者知情人士解答
另外double时间是11月14---11月25

来自主题: PennySaver版 - double coupon是怎么操作的
应该是自动double的吧。
5开头的胖子能double,9开头的就不能double。
有的5开头的胖子也写着不能double,但是如果小二不看直接扫了,也能double的,小
二仔细的话就会手动把double去掉。所以现在越来越多写明不能double的胖子都是9开
头了。
我这里没有kroger,不过道理应该差不多。

你的解释我还是不懂。麻烦看看我的理解哪里是错误的。图就是13楼的图。
一开始第一次踩离合之前,蓝齿轮和金色的轴(和粉红齿轮)是硬连接一起转的。假如
普通降档,踩了离合以后,他们还是硬连接。没关系。但是挂了空档以后,蓝色齿轮和
金色轴(和粉红齿轮)分开,车子凭惯性走,速度稍微下降,所以金色轴(和粉红齿轮
)转速也稍微下降。同时蓝色轴凭惯性转(这时它和发动机也分开),速度也下降一点

空档不滑行,换档快一些好像double clutch是没有意义的。 只有在空档滑行了以后,
蓝色齿轮的速度已经被发动机转速严重影响了,才有必要double clutch。
另外蓝色齿轮(外加红色齿轮)的重量好像很小的样子。比如我们空档时候快速松离合

我以前在板上看到了,记了个思路,但是忘记帖子的地址了,
题目就是reverse一个double还是float number(记不太清了)
比如123.456, 转成 321.654
思路是先把123转成321,然后把0.456扩大成只有整数(也就是456),记录下来小数点
移了几位,然后反转整数456,得到654, 再把小数点移回去成0.654, 和前面得到的
321相加。
我今天按这个思路写了写,发现小数点右移的过程有点问题,因为我不太清楚java到底
怎么存小数的,给的stop condition不对啊,永远meet不了
大家能帮我看看这行怎么不对吗?

这几天根据您的建议,看过youtube上一些double push的视频,开始用我的powerslide

今天左脚刚向内侧push,外缘一下就蹭地上了,可能轮子也悬空了,右脚还没来得及跟
过去,俩脚就拌蒜了,立马失去平衡,右侧着地了。请教:
(1)是不是我的左脚frame的offset还是太过偏内侧,抑或我的double push技术尚不
过关?我上frame时,前孔还是在最内侧。我左转cross over的时候有时外缘也会触地
,但极其轻微,外侧包着的那块黑皮子基本看不到擦痕。
(2)感觉powerslide的boots比其它牌子的鞋宽(也是我穿着舒服的一个原因,基本没
怎么heat-molding)。是否宽底鞋上frames的时候更应尽量置中?
(3)最近在等另一双4x100。个人理解越大的轮子离地越高,应该更适合double push
,是不是这样?对了,你用5x84的时候是不是感觉比5x80容易double push?
(4)因为以前从没试过double push,不知其对速度是否真有明显增加?看

3.3: Doubling Down
Among the more profitable player options available is the choice to "double
down". This can only be done with a two card hand, before another card has
been drawn. Doubling down allows you to double your bet and receive one, and
only one, additional card to the hand. A good example of a doubling
opportunity is when you hold a total of 11, say a (6,5) against a dealer's
upcard of 5. In this case, you have a good chance of winning the hand by

我再仔细问一下。一开始第一次踩离合之前,蓝齿轮和金色的轴是硬连接一起转的。
假如普通降档,踩了离合以后,他们还是硬连接。没关系。但是挂了空档以后,蓝色齿
轮和金色轴分开,车子凭惯性走,速度稍微下降,所以金色轴转速也稍微下降。同时蓝
色轴凭惯性转,速度也下降一点点。假如我们立刻挂下一个档位,两者转速应该是基本
一样的。或者差不多,所以如果空档不滑行,好像double clutch是没有意义的。只有
在空档滑行了以后,蓝色齿轮的速度已经被发动机转速严重影响了,才有必要double
clutch吧?
另外蓝色齿轮的重量好像很小的样子。比如我们空档时候快速松离合,车子基本没有任
何震动,说明蓝色齿轮很轻,就算用同步器去托它,也不是很累的事情。
最后如果double clutch,第一次轰油门以后,蓝色车轮的转速和金色轴的转速之间基
本没有关系了。完全是要求轰油门可以把两者转速差变得比让两者自由转动一瞬间以后
的速度差还小。这个感觉已经不是没有必要,而是不可能了。所以普通情况double
clutch应该是损害同步环的。只有在空档溜车以后double clutch才可以有正面作用。
不知道这个理... 阅读全帖

来自主题: USANews版 - Poverty Doubles Over the Past 30 Years
Poverty Doubles Over the Past 30 Years, Despite Robust “Economic Growth”
by Mike Krieger of Liberty Blitzkrieg blog,
One of my favorite lines about the current oligarch theft continuing to
occur throughout the world is courtesy of the “Artist Taxi Driver,” who
likes to state:
“This is not a recession its a robbery.”
Truer words were never said, but this theft goes back a lot further than the
latest economic catastrophe. As we all know by now, real median wages haven
’t increased in the U.S. ... 阅读全帖

有一个帖子在double taxation上面一个描述是错的,所以说明一下。
double taxation是专指dividend之类的分红。公司交了税后,如果再付给股东股息
dividend,股东在股息上面还要交税,这种叫做double taxation。
把double taxation放到短期,或者长期资本利得上面,在accounting,finance,
economics的领域里面,没有人这么说。
美国税法上面区分短期和长期资本利得。短期是指投资在一年以内套现,按收入税收,
top marginal会在39.5%. 长期是超过一年投资套现,税是15%到20%。
对冲基金和私募一般收2%-20%,2%的根据资产规模收,再在盈利部分收20%,在盈利部
分收的,但不是属于自己贡献的那部分钱,而是客户贡献的钱产生盈利的20%,就是
carried interest,这个也是每年的performance income。
很多基金管理公司的盈利是长期投资结果,所以很多基金公司就把carried interest也
当作长期投资盈利,在税法上好像应该只交20%的税,即使这个其实是每年的

吃到一张 double parking的 ticket, 当时我技术上确实是double parking, 都停在
了路中间,但是这不能怪我呀,
我住在那里,curb边上都停满了车,难道要我跨几条街把东西搬回家吗? 门都没有!
所以我决定要contest,直接要求hearing
今天去了芝加哥南边最乱的90多街的city hall上庭。之所以去这里是因为根据我的经
验这里都是黑人,作为非黑人总是会有些优待,果然虽然里面黑压压一片,但是我就没
有排队,直接就上庭了。哈哈。
首先是装模作样的宣誓,然后我就拿出我的资料,首先说我就住在那里,请看ticket的
事发地址和邮寄地址,然后,一脸坏笑的宣读 芝加哥city code 9-4-010这一节关于
parking的定义: "“Parking (to park)” means the standing of an unoccupied
vehicle otherwise than temporarily for the purpose of and while actually
engaged in loading or unloading... 阅读全帖

家里现在灶用了多年,烤箱坏了, 想买一个新的。
平时烤箱用得不多(也可能因为坏了很久,也就没有学习没有用), 有必要买一个
double oven的吗? 除了贵点,Double oven相对于single oven 有没有什么特别大的
缺点?比如每个空间小一些,可能不能烤很大的东西?
买doubel oven主要是考虑这个东西要用很多年, double oven和single oven差价也不
是很大,不如一次到位。
下面这款怎么样?

对,不指望房价影响,就希望大部分buyer看到double sink更喜欢。
个人觉得60" double有点小,要更长的double才够气派
看来还是小一点无所谓,还是double sink了?
