公开水域游泳技巧
In my many years in this sport, I have never seen any reasonably
complete article in the magazines dealing with open water swimming (they
seem to rehash the same basic stuff every few years). A lot of them talk
about how to draft, or tell you to look up every few strokes to stay on
course, but very few seem to deal with the subject in much detail.
在我多年的运动生涯中，我从未在任何杂志中看到过合理的、完整的对付公开水域
游泳的文章（他们似乎只是每几年训练一些新手）。很多文章只是谈一些如何跟随游，
或者告诉你几个动作后向上看，以保持航线，但是没有多少文章对这个话题说的足够详
细。

对不起，我说过我们这儿没人计算pre-test probability score的，所以我说的pre-

发帖数: 17328 | 17 我说很清楚了，probable cause是警方的根据一些事实的主观判断。不说明“强奸即遂
”成立或者“性交成立”，至于警方如何做出probable cause的结论，那是警方的问题
，而且没有统一标准，我认为是probable cause的你可能认为不是，都是可能的，没看
到卷宗之前都是瞎猜。
在重申一次，不是给刘强东喊冤，也不是说他没打炮，也不是说警察没证据。我只是说
，警察报告里的probable cause-rape-completed，不说明任何问题，只说明警方根据
某些叙述和事实“认为”刘强东把女方强奸了，仅此而已。
假如，是后发现真是拿黄瓜捅的，警方的逮捕报告一样是“probable cause-rape-
completed”。因为警方第一时间会认为刘强东捅的可能性远大于黄瓜捅的可能性。 |

理科生，本科都上过概率论，（文科生不知道，或许没有，所以她们难以理解）
里面有句名言就是： 小概率事件必然发生。
例如，万分之一的机率，你可以打筛子打出6个6的豹子。然后，你打了1亿次,出来了。
结果：肘子抓住你这6次的豹子， 连续质疑------------我问你，你怎么解释？？？？
另外那999999次没有用，那些忽略掉！！！！！
*****************************************
肘子，只质疑已经发生的事儿。-----------但，发生的事儿，是已经发生的。
概率论，不是来讨论既成事实的。而是用来估计未发生的事儿的！！！！！！！！！！
具体到每个人，谁的... 阅读全帖 |

Given that there is significant existing variation in human intelligence,
it's curious that we are not all much smarter than we actually are.
Besides the well-known costs of higher intelligence (e.g., more energy
use, bigger heads causing more difficult births), it seems that being
smart can be a disadvantage when playing some non-zero-sum games. Here is
one example.
Consider an infinitely repeated game with 2n players, where in each round
all players are r... 阅读全帖 |

If you dig a woman who’s behaving in the following ways, the whole pursuit
is probably not worth your time. Yes, women like to be chased, but only by
men they’re actually interested in. This article is for men who already
know the woman – this not for someone you’ve just met online and haven’t
seen face to face; that’s a whole other situation. This is for someone you
’ve actually met.
1. She never asks you to go into detail.
Ok, let me be more specific – she never asks you to go ... 阅读全帖 |

灌水还会去写个模型的人，敢问世间有几何？
倘若你写个物理学模型，我估计无法辩驳。不过既然谈到投资学，那我再来将你一军。
“巴神是唯一一个从少年进入投资界保持到88岁高龄的挣钱投资记录的，驾驭了
randomness的神”。如果挣钱是指收益大于投资，那么这个本身不是什么奇迹。附件是
个 Facts: How an investment of $1 at the start of 1900 would have grown by
the end of 2008, assuming reinvestment of all dividend and interest payments
. 所以如果有足够耐心持续投资108年，赶上这个阶段的美国，任何一个人都挣钱了。
巴神之所以被认为是神，不是因为长期挣钱，而是因为挣了风险最小的收益率最高的钱
。以那个108年里挣钱最多的股市为例，其年化平均收益率是11.1%，收益的标准差是20
.2%。巴神的17%和10%与股市相比，return更高，risk更小，所以确实有过人之处，因

IN GOD'S WAY
SCHOOL-DAYS
I.
In the melting snow on the hill-side by the sea, in the last rays of the
evening sun, stood a boy of fourteen, awestruck. He looked toward the west,
out across the sea; he looked toward the east, over town and shore and the
broad hills; in the background still higher peaks rose far away in the clear
sky.
The storm had lasted a long time; it had been more terrible, too, than any
the old people could remember. In ... 阅读全帖 |
