Rather than refer to all your "numerous enough to be statistically
significant posts", please give a straight answer to a straight question:
Was TSLA one of your "been right and consistent(ly) profitable" trades (
either physically or mentally) or was it one example of your bad luck and
non-perfection?

靠球星个人能力的球队都consistent不到哪儿去,比如雷霆,火箭。其实walker才1200
万,也算白菜价了。爪机都比他多1/3。

算了,不讨论沃克了,免得黑子又来说大家攻击他。沃克这个表现还是挺consistent的
,前几个赛季FG%不到四成,这个赛季三天两头来几场这样比赛很常见的,今年三月份
的表现是他职业生涯最高的命中率了,到赛季快结束又是有一场没一场的

你说的是连续拉的consistenCY还是拉球的稳定性?

Mostly the 拉球的稳定性 for returning serving balls.
For 连续拉的consistency: it becomes the footwork, and after the first loop
of an back-spin ball, it most likely top spin instead of backspin unless it
comes from a chopper.
Why 拉球的稳定性 is important: becasue the coming ball has different spins
and speeds.

来自主题: Pingpong版 - Secret of consistent RPB looping
能解释一下吗?
"My previous RPB looping has a factor, i.e., lifting forward factor due to
handling under-spin balls, which factor is wrong and which is the reason of
un-consistency because lifting will cause errors due to the different speed
and spin of the coming ball so that it is difficult to produce a perfect
lifting to counter the back-spin."

偷换概念。你明明问的是:如何consistently大力击球。如果只是不想失误,不要发力
对抽,跟对方刷上旋就可以,向豆子方向发展即可。

agree and disagree. The fact is the same exact shot I would not miss in
practice, so why do I miss in the match? Sure, you can argue it's the
footwork, but why do I have the footwork during practice and not during
match? It's still mental, mentally got tight, mentally not as confident,
mentally thought I should do something more (change) with the shot. All
those caused the lack of footwork during the match, lack of footwork yield
lack of consistency. But it still started with mental.

我有一个困惑,有时你碰到一个对手,如果你正常地打,对手很适应,处处受制。如果
你打地更aggresive一点,虽不是你的最consistent的shots,但对手也很不适应,这样
你才有机会。有时我觉得甚至是越早换越好。
同意黑导说的这些都取决于mental,如果mentally relaxed,虽然不是最经常练习的
shots,但也不一定就UE

MySQL cross data center replication,现在需要在一个master写,而slave或另一个
master马上(一秒以内)读出写入的值。请问如何做到?我听说mysql的replication不
是strong consistent,也就是replication是async,需要一定的backlog才replicate
到其他data center。

你计数器算完,最后出票结果还得存在外围数据库里,这不就是 master-slave 吗?
可惜 计数器这个master 不知道 slaves 的存在, data consistency 根本无从维护。
一个 web server 从 计数器拿到一张票, 然后 crash 了, 这张票不就丢了吗?

来自主题: Programming版 - cassandra的eventual consistency怎么破?
quorum read/write 延时会成倍增加啊。其实只要quorum write就行了,但那样也有点
不值得,毕竟只要绝大部分时候consistent就行。但是因为写和读之间的时间非常短,
怕到不了eventual那一步,那样的话inconsistent就会成为常态。
话说有人知道eventual是几秒吗?貌似facebook也是受不了这个eventual改用别的了。

来自主题: Programming版 - cassandra的eventual consistency怎么破?
问题是你写的consistency level 是什么?如果是ONE. 如果写向A那不能保证B会有你
的数据, 如果A down 了,可能你就从B读不到数据。
避免这种情况,就要用quorum write. 你要等到两个node 都ack 了,你的写才是成功
的。
read 类似道理。

With quorum read/write, it's strong consistency. And you are looking at
write at ms level, read a few times slower.

我的理解是。HBase is based on HDFS. From HBase's perspective, the HFile only
need to store one copy. HDFS保存多分来实现data failure. 所以从hbase角度。是
strong consistent.

来自主题: Programming版 - Consistency做好了不容易
关键就是fail以前的最后一个transaction总是不确定的。不论你采用什么机制,ack,
ack of ack, ack of ack of ack。。。
这是一个很简单的逻辑问题。单机都存在这个问题。这还是在不追求性能的条件的理论
最优解。多机partitioning只不过放大了这个问题。
如果追求性能,允许异步通信,那么单机不确定的数量会大于1。
刚看了jepsen,zookeeper也会出现fail以后elect多个master的问题。
因此,简化版本,两台单机client/server transaction。也必须两边记录journal log
。fail以后要有个两边对账的机制,才能保证100的consistency。
事实上,我没看到有这么做的。

来自主题: Programming版 - Consistency做好了不容易
我觉得你说的这个超过ACID的范畴了。
一个transaction玩了,client说commit,server成功执行,并且执行确认操作(ack),
到此位置是consistency和durability的界限。如果因为什么原因client没有收到这个
ack,transaction也算是成功了。不然如你所说,ack of ack ...起来没完没了了,
就变成黑暗森林了。ack丢失的情况下要保证系统成功运行,得有强壮的业务逻辑才行。

well, let me make it concrete. (and u r right, the date attr is redundent, it's just part of the dataset)
I took record of stock price every trading day, for each tuple in the db, I
have 3 attributes:
date, previous_day_close_price, close_price
and I want to check if the system is consistent, if I see something like:
