来自主题: TexasHoldem版 - which river bet will you call?
Why to call 2nd one? To me, only bluff catcher. The villian could have medium
pair on hole(or paired 88). After check on turn, lead out on river. If villian bluff and you beat is big Ax. I bet the poss. is not big since villian is OOP.
The first one is at board line to me. Either you are deeply beaten. Or you still
beat a few Ax. More likely, being beaten.
I play Rush NL100 today a little. Run really dry. The only hand(before the last one) I got is AJo. Raise at UTG+1 and fold to 3X from BTN.

来自主题: TexasHoldem版 - Why we should not slow play strong hand.
I am horrible at hand reading, and hopefully I will improve. I don't see many
hands bet three streets with this sizing here. I guess set/two pairs would
bet larger on the turn, and check river, so lots of hand combo are out. your
river bet means Ax/9x, right? I think 89/J9/Q9/K9 bets the turn, but what
Ax hands bet the turn, A9?

if this read is right, then what hands AFTER utg raise and your call, would

1) you hold AA, if he holds any big Ax, the chances that anyone else holds
another Ax is next to zero. and it also becomes unlikely that another guy
would hold a big pair like KK/QQ (taking out K or Q from AK/AQ);
2) if he raises with KK/QQ/AK, then you lose a great chance to build a big

来自主题: TexasHoldem版 - A few hands last few days
I like your play in hand 1. Check/call on 998 flop is good to control the
pot and maximize the value.
For Hand 2a, I suggest that you should continue bet on turn as well. Since
villain may call your C-bet with any face cards on the flop, you do not want
to give any free card to him on the river. Plus JJ is not that powerful to
slow play here. Any face card on river could shutdown the action and there's
also some possibility to hit villain's range. Then you lose pot.

you're talking about the worst situation for your QQ hand (villain calls

in fact, there're quite some other possibilties too:
1) Ax hits Kxx, Kx hits Axx, totally miss;
2) x hits a middle pair or even top pair, like AT hits Txx and pays you off;
3) hands like 99/TT may pay you off too, either re-shoves preflop (take your

對player的那把牌,A8對Ax,flop是877,player下注2700,我fold了。起初猜他是Ax
或一中等對,他下注後,認為是中對,所以fold。其實如果是中對的話,player初始
bet不會是1200。而且後來比較放鬆了,開始打字說話,精神不集中。

pre flop:一般raise hand至少有大对,double suited and at least with one Ax,
4 cards working together or at least 3 cards working together (like T987 A98

That is why OOP calling with speculation hand is not profitable IMO. You
have chance to lose a lot of money but you didn't get paid enough when you
hit a big hand because you have to act first. Although calling a raise at
this spot is nothing wrong because of the pot odds.
I would flat call the flop as well, you hit the board too strong that nobody
had a piece. UTG donk bet range probably include any pairs, and any Ax hand

来自主题: TexasHoldem版 - how to play this hand better?
1. I could bet flop big, 7 dollars pot, I should bet 5 or 5.5 dollars?
2. I should check the turn?
Because villain calls my CB on the flop, the range is AX or flush draw, I
can not get 3 streets of value from AX, it is the time to check turn, or
villain has me smoked, I have to see the free cards.
3. If I do check the turn, with a non-heart flops, I should bet/fold the
river.
Any thoughts?

因为我没有showdown value,他不cbet,我肯定要bet。
----->因为对手有King, 有 尖子,所以知道你多半啥也没有,他bet,你弃牌。所以他要
获得价值,只能等你下注。
问题二: why bet on Turn?
因为他check call on flop,通常这样的打法是有一定showdown value的牌,但想要
pot control。就这首牌来讲,他可能是Ax,或者QQ往下的对子。如果他是JJ往下的对子
,肯定会fold to 2nd barrel。

切向分量不是简单的w*r
退一步考虑
假设盘完全静止,瞬间盘质心获得一个速度Vc
因为支点固定,这个速度意味着盘在做某种转动
转轴唯一的要求是垂直Vc,过支点O,方向都不确定
假设这个方向Ax和OC方向,也就是盘的法向成theta角
可以算出来角速度W,
考虑系统动能,质心有1/2MVc^2
剩下转动有1/2I*W^2,这里的I是盘对Ax的转动惯量,
如果分解,这个W可以分解成平行盘方向的翻转分量w1,
和自转分量w2,动能可以写成
翻转部分1/2Ib*w1^2 + 自转部分1/2IA*w2^2
如果开始就有自转w0
自转部分,因为速度Vc引起的转动其实是总能量是1/2IA*(w0+w2)^2
这里自然有一个IA*w0*w2的交叉量
你要愿意,可以把w0+w2当成自转号称没有交叉量
但是这个东西和初始状态的w0关系就模糊了,意义不大

我只会做线性模型,很简单,不知道行不行。下面是做法:
这个问题就是求解线性问题:Ax= B, A是输入(1x6 矩阵),B是输出(1x34 矩阵)
,x是变换矩阵大小是6x34。
求解必须有很多组Training数据,每组数据有一个输入,一个输出。假设有N组数据。
于是把所有数据合起来,A变成Nx6矩阵,B变成Nx34矩阵。
现在Ax = B是个矩阵方程,可以直接求解x矩阵,方法是对矩阵A使用伪逆。

setcc是几86出来的指令?
另,也可以:
lahf
shr ax, 14 //把0-flag移到最低位
and ax, 1

来自主题: Programming版 - C++ 做线性代数,方便使用的库?
this is called least square problem
AX=Y -> A'AX=A'Y -> X= inverse(A'A)A'Y -> in matlab X = pinv(A)*Y.

Ok i found this code online, works fine except i want to see date in the
xlabel.
import numpy as np
import pandas
import matplotlib.pyplot as plt
from matplotlib.finance import candlestick, candlestick2
import matplotlib.dates as mdates
from pandas.io.data import DataReader
import datetime
# get daily stock price data from yahoo finance for S&P500
start = datetime.datetime(2015, 11, 1)
end = datetime.datetime(2016, 2, 11)
SP = DataReader("spy", "yahoo", start, end)
SP.reset_index(inplace=True)... 阅读全帖

其实另外一个简单办法是笼子上标cage number。这样笼子可以自己起名字。比如AX001
,AX表示是某个line,001表示这个line中的cage。如果两个line杂交,比如AX和BP杂
交可以起名AXBP。这样每个笼子还想就不需要超过5-8个number就可以了。这样直接耳
朵打洞就好了,左右耳朵很容易辨别。这样你的老鼠记录就是AX001EP01啥的。
一般在自交系超过一定代数之后就不需要记代数了。但是杂交的需要记录第几代。
至于管理软件:
1. Jackson lab有个老鼠的管理软件,可以下载了直接用。不过比较复杂。
2. 另外一个办法是自己写个简单的database interface。比如用access或者mysql做
database,然后自己写个web interface,管理起来也很方便,而且容易customize。但
是需要学点儿code。
3. 用spreadsheet也可以,记录比较简单,但是管理,找老鼠,建立谱系等等都不方便
。当然spreadsheet也可以当database,然后自己写点儿code做interface来管理跟2一
样。
4. 还有很多

Let's say, genes in column A and peakvalues in column B
(from row x to row y)
1. Sort whole dataset by columns A & B (A to Z and smallest to largest)
2. Fill rows x to y in column C with =countif(Ax:Ay, Ax)
3. Copy column C and paste special "value" to column D
4. Sort whole dataset by columns D & A (smallest to largest, A to Z)
The data you want will be shown at the top of the sheet with "1" listed in
column D.

1. 哥们,我是做系统的好吗?系统方程当然是AX = X'
没有X',你的系统变化嘛?人的状态不变化你研究个啥啊。
你就说AX = B的B是什么行不行?
2. 当然当然,我绝对承认研究蛋白是可以的。蛋白是影响很大的,
对这个病 是重要的。有办法搞清楚这个蛋白对其他身体状态,
身体其他部分重要嘛?
