A. The Goldfish Arrests.
On March 12, 1988, at approximately 2:00 p.m., PRC police officials arrested
Wang on the streets of Shanghai. Four men approached Wang, kicked him, and
dragged him along in the street and into a waiting car; once in the car,
Wang was blindfolded, kicked again, and sworn at by the arresting officers.
Wang knew he was being arrested for his participation in a heroin
transaction.
The officers took Wang to the Chang-Ning Branch of the Shanghai Public

失巨大，所以什么都用上了，就是要保证万无一失。因此我们的PROD数据库是HA+DR，
而且还有每天RMAN备份到VTL上。非PROD的就省了很多。很多没有HA的，备份也马虎很
多，省钱啊。 |

俩孩子长大了吧。好久不见。Arsura据说海归了，找不到他了。
我们应该使用connection pool的。前面的group lead在getConnection的try/catch 的
catch里放了普通的connection function （我们用于local debug用的）。他在get
connection里有个typo，造成4年来我们一直用connection string来setup connection
。从没测试过connection pool。

然后去编译，因为受限于os，你当然只能用vi咯
老赵，别说了。越说越离谱！ 真心看出来你木有在linux上面搞开发， :-)。 还把C的
源代码部署到 prod env 上去编译？ 你的意思是放到客户的prod env上面编译去？ 你
蛮搞笑的！ 别说了， 越说越错！ ^_^

发帖数: 318 | 41 你那个"反例"给得不好,因为极限是负无穷大也算是有极限的.
实际上log(1+an)约等于an,所以\sum a_n=-00基本上和\prod (1+a_n)=0差不多的,不能算
是反例.
两个反例
1.
a_n=(-1)^n*(n+1)
\sum a_n存在,\prod (1+a_n)不存在
2.
a_n=-1 n=1
随意,但要保证\sum a_n不存在 n为其他值时
\sum a_n不存在，\prod (1+a_n)=0

什么乱七八糟的，hft只是citadel一个组而已，当然是比较赚钱的，不过也大不如前了
。hft分两块，prod和research，prod的头是个棒子，叫julian lee，research当然是
赵鹏管咯，global head嘛。research写algo，prod负责run，一般小矿矿也不知道自己
algo run的如何，当然自己会keep一个paper account，要是被拆了，基本肯定algo不
赚钱。
kcg/getco大不如前，现在基本在糊口。hft mm现在很难做，最近做的最好的应该是
jump。不过citadel fi hft最近比较猛。 |

答案是７。我有点不清楚这个７具体指的是什么？
（１）ＤＯＵＮＴＩＬ一直到ｐｒｏｄ＝６ ｐｒｏｄ＋１＝６＋１＝７
（２）ｄｏｕｎｔｉｌ一直到检查到ｐｒｏｄ＝７才会不执行，ｐｒｏｄ＝７
