目前是SQL Navigator与VSS 6.0
准备升级到TFS 2010,还能用SQL Navigator吗？google了一下，好像SQL Navigator 6.

有大侠用过吗？
如果不支持的话，只能在vitual studio里建一个database project了？

发帖数: 188 | 11 I bet you haven't actually tried EX. :)
but good point on VC vs. STP. biggest challenge in large scale data center
is to find a way to get rid of stp. cisco came up with vss for 6500 and vpc
for n7k/n5k. juniper came up with vc, force10 seems go for vc too. haven't
tried running vc at juniper EX8k data center core - only at access layer so
far, but N7k's vpc at core seems running well. not sure how good THRILL
would be in future. |

发帖数: 28013 | 19 我不知道，我是个entry level，正在学习JUNOS。
从系统看，J家只有一套，如果勉强算netscreen，也就是2套。J家的产品也很多很乱，
不过貌似我感觉他家要淡化netscreen，强推srx。
有一点J做的很离奇，而我也认为是一个发展。就是MX，M，SRX直接没有直接的level区
分。SRX可以做很小，也可以做的很大，有小的port，也有大port，系列名字是一样的
。未来还可能淡化J系列，没有某个系列是access layer这样一个概念，直接3-5套产品
从低到高，然后一套系统统一天下。
这样的好处是产品线单一，出货，support，管理cost大幅减小。用户的training cost
也小。
以上都是猜想------------------------------------------------------
技术上考虑，junos的稳定性和个别feature，比如config存放50个，commit实施，包括
类似VSS的更新，都很赞。价格也许比C便宜？
AAPL嘛，按比例算，那是赚翻了，按价值来算，真是不值一提，我entry level，没存

CVS: C stands for "Concurrent" :-) You must have used VSS before, CVS
doesn't require user to lock the file in order to edit, in fact, it encourges
user to edit the same file at the same time. Just make sure before committing
your changes, do update first, it will automatically merge (very good) the
changes if your version of file is out of date, otherwise, it will report
conflicts and prevents you to commit until you resolve the conflicts. I don't
recommend to use CVSNT, it is not stable a |

Source code is stored in Visual SourceSafe. A bug tracking system (MS SQL

My project is to build a web interface, so users can select Java source code
from VSS to a project, build it and obfuscate, then associate it with bug ID.
The tools come up to my mind is:

Maven -- I didn't use it. Don't know whether it is appropriate
ClearCase -- never use it, is it configurable to do the j |

发帖数: 14569 | 26 As to my imagination, I believe Rational or other company will have product

already in VSS. And I am not the boss to say: let's convert them to integrated

Most important of all, any product, if it is not open source, always difficult
to customize. Yet our company needs it customizable. |

发帖数: 488 | 34 原题如下：
given function V in terms of S and t,V(S,t)
parameters are:rho,alpha,lambda,theta,mu,sigma
the PDE is:
rho*V(S,t)=alpha*S+lambda*(mu-S)*Vs(S,t)+theta*(Vs(S,t)).^2+0.5*sigma*(S-S.^2)*Vss(S,t)-Vt(S,t)
S is in [0,1],and t is in [0,T],T is a constant.
the boundary condition is V(S,0)=0
Vs is the first-order partial derivative of V wrt S, and Vt is first-order partial derivative of V wrt t.

rho*V(S,t)=alpha*S+lambda*(mu-S)*Vs(S,t)+theta*(Vs(S,t)).^2+0.5*sigma*(S-S.^2)

partial derivative of V wrt t.
现成的function（也我们老师自己编的，不是MATLAB自带的），newton那个总说有错误之

S取n个nodes，t取m-1个nodes，n和m分别是polynomial的order。这样有n*m个待定系数C
（nm*1的向量）和n*m个方程，只是关于待定系数的方程是非线性的，把residual的方程
代入到broyden里面，它就帮算最后的C是多少。我还是没有自己算jacobian，因为脑子总

发帖数: 150 | 36 怎么说呢?非一日之功的说.
VHDL是最简单的了.现在常用的硬件设计语言大概就VHDL和Verilog
两种,我个人觉得verilog更简明,更好学,但基本上都和计算机语言
例如C差不多,比较好上手.然后就是用Veilog_XL(CADENCE)或者VSS
(SYNOPSYS)进行逻辑模拟验证逻辑功能,之后还可以利用SYNOPSYS
的综合工具综合成网表,然后再自动布局布线成版图,这属于半定制
的设计.另外有了VHDL语言对电路的描述以后好象还可以用自动工具
生成FPGA,这个我没有做过,不知道.
要是自己从版图入手设计就很烦了,一个小电路画起来也是非常费劲
的,所以有些公司里有一帮人专门画一些小单元电路,进行建库,另
一帮人进行高层设计,然后自动用这些库来生成版图.
Cadence是一个很大的工具,学会用其中一种功能不难,要想面面俱到,
是需要时间的. |

发帖数: 13 | 45 对于bjt，e，b，c电极上的电压分别是Ve,Vd,Vc；
对于mos，s，g，d电极上的电压分别是Vs,Vg,Vd；
在bipolar电路里，常常有许多bjt的c电极接在一起，接在最高电位上；许多bjt的e电
极接在一起，接在最低电位上。因此通常称最高电位为Vcc，最低电位为Vee。
在早期nmos电路里，常常是有许多nmos的d电极接在一起，接在最高电位上；许多nmos

if you insist on doing that, you are far better of with a 3-pin voltage
