a*****a 发帖数: 1429 | 5 If the firmware supports optware well, and can use either a USB flash or a
file on a CFS file system, the router is certainly the 神油 next generation.
With 128M RAM, 2 USB ports and much more stable and advanced hardware, it
can be easily turned to a BT/Emule download machine, an asterisk server, and
etc. |

g*****g 发帖数: 34805 | 6 In most cases, you don't need to create a schema on the fly.
So all the CFs are in every node before you start your app.
And then you can add new node to the cluster and let it replicate. |

natively as a hadoop data source or sink.
:现在apache已经开始整合cassandra跟hadoop了
没有的事儿。怎么整合?cassandra on hdfs? mapred optimization on cassandra?
凑合粘乎一下还行,整合就不可能了。 |

,话说你为什么关心你自己的app运行时间?你不是开发kernel的这个基本没法控制?
难道你必要要实现real time?。而且还取决于看你程序是CPU bound还是IO bound了 |

vert.x做了一个简单的file system
理论上这个往上做的话,可以作出一个nosql db出来
就像hdfs -> hbase这种关系
或者cfs -> cassandra
另外一个关系就是vert.x对于nosql的支持比较重视
因为nosql大多数对于async的api提供得比较快
相对于db而言,所以vert.x比较快地跟nosql接轨起来
所以选择persistence的时候,选到了nosql的话
jvm上留给你的选择就不多了,比如传统的servlet+spring+hibernate这个
就不见得很合适,因为api都是同步的,vert.x都是异步的
vert.x不用马上替换,你可以一点一点加进去
vert.x3有一个很容易integrate到现有系统的方法
你看文档,只需要拿到Vertx vertx这个obj就可以做了 |

s********k 发帖数: 6180 | 10 今天又看了下,K8s下docker的default cfs_period = 100 ms ,这个即使linux那个
fair schedule的最小slice time,会不会有些k8s的pod被Linux schedule出去100ms+
?会导致一些tail distribution的delay变得很差?k8s好像不能够设置更小的CFS了 |

g*s 发帖数: 12 | 11 在线硬盘加密程序是非常重要和有用的:
在internet上游很多好的免费硬盘加密程序,它们对你的操作系统来
说是完全
透明的.下面所列的几个软件都是经过测试的
- 如果你用Unix,你可以使用CFS v1.33
安全加密机制.绝对不要用那些被出口的加密程序,它们的有效密钥长度
被缩短了!
- Triple DES
- IDEA
- Blowfish (32 rounds)
加密你的Email!
- PGP v2.6.x 是个不错的工具.
如果你想讨论重要的事情的话,加密你的电话.
- Nautilus v1.5a 是迄今最好的
当你连到一个unix系统时加密你的终端.
一些人可能正在sniffing或者监视你的电话线:
- SSH 是最安全的
- DES-Login 也不错
千万别忘了:锁上你的机箱盖!

r*****z 发帖数: 176 | 12 谢两位的帮助,分析的很透彻了。
听你们的意思,好像也要直接跟公司问的。 只是我跟这家公司没有任何关联,没法直
接上去问。 所以想知道SEC filing里面有没有哪个文件会直接说的。 10-K里面只说
face value,不提这个discount的细节。Filing里面还有一个貌似credit agreement的
东西,里面关于这个bond的什么细节基本都说了,就是没有一点关于这个discount的事
。 至于CFS里面,因为他们当时发了好几个bond,反正都混在一起,看不真切。
还有,这个discount的amortization,是一定要straight line吗?如果这样,可以从
两个时间unamortized discount的差别来推算,至于是不是有financing cost在里面,
就无多所谓了。
另外,关于picollo解释的一个细节:bond issued under par,是指effective rate高
于coupon rate吧?我不是会计科班,不知道是不是理解错了。

h*y 发帖数: 1289 | 16 I'd like to stress the following points:
1. "Risk neutral" and "Risk free" are two different concepts
2. Risk neutral probabilities exist if and only if there is no
arbitrage.
3. The risk neutral probabilities are unique if and only if
the market is complete.
4. Under risk neutral measure, or say in the risk neutral world,
investors are indifferent to risk, requesting no additional
compensation for risk(risk premium), therefore, CFs are discounted at
risk free rate.
