3、使用如下命令更改密碼：
shell> mysqladmin -u root -p password ‘newpass’
Enter Password:*******
出現Enter Password的提示后輸入原來的密碼oldpass即可。
讀者可以嘗試其它所有本章介紹的方法。
4、首先以root用戶的身份連接到服務器：
shell> mysql -u root -p
Enter password:*******
出現Enter password提后輸入root用戶的密碼，然后即進入mysql客戶機的交互模式，可以看到下面的提示：
Welcome to the MySQL monitor. Commands end with or \g.
Your MySQL connection id is 4 to server version: 3.23.25-beta-log
Type help or \h for help. Type \c to clear the buffer
mysql>
然后發布查詢，直接鍵入題目中的語句：
mysql> Select User,Host FROM mysql.user
On-Line MCMC Bayesian Model Selection
This demo demonstrates how to use the sequential Monte Carlo algorithm with reversible jump MCMC steps to perform model Selection in neural networks. We treat both the model dimension (number of neurons) and model parameters as unknowns. The derivation and details are presented in: Christophe Andrieu, Nando de Freitas and Arnaud Doucet. Sequential Bayesian Estimation and Model Selection Applied to Neural Networks . Technical report CUED/F-INFENG/TR 341, Cambridge University Department of Engineering, June 1999. After downloading the file, type "tar -xf version2.tar" to uncompress it. This creates the directory version2 containing the required m files. Go to this directory, load matlab5 and type "smcdemo1". In the header of the demo file, one can Select to monitor the simulation progress (with par.doPlot=1) and modify the simulation parameters.
Atheros無線芯片AR-6000系列wince 6驅動源代碼(這東西我也沒用過別問我,我是搜別的wince資源搜到的)
AR6K SDIO support. Requires firmware 1.1 on SD13 cards.
readme:
Atheros Communications
AR6001 WLAN Driver for SDIO installation Read Me
March 26,2007
(based on k14 fw1.1)
Windows CE Embedded CE 6.0 driver installation.
1. Unzip the installation file onto your system (called installation directory below)
2. Create an OS design or open an existing OS design in Platform Builder 6.0.
a. The OS must support the SD bus driver and have an SD Host Controller driver (add these from Catalog Items).
b. Run image size should be set to allow greater than 32MB.
3. a. From the Project menu Select Add Existing Subproject...
b. Select AR6K_DRV.pbxml
c. Select open
This should create a subproject within your OS Design project for the AR6K_DRV driver.
4. Build the solution.

Without this, the debugger spontaneously fails!
1 - Install mdk315b
2 - Replace the files:
\Keil\ARM\BIN\ARM.DLL with one from mdk305a\Keil\ARM\BIN\ARM.DLL
\Keil\ARM\BIN31\ARM.DLL with one from mdk305a\Keil\ARM\BIN30\ARM.DLL
\Keil\UV3\UV3.DLL with one from mdk305a\Keil\UV3\UV3.DLL (*)
3 - Use KeyGen (Ver3p4 works)
Select ARM, With computer ID code , External CID code
and RealView MDK (or RealView RL)
Note: Must replace DLLs before entry of serial
(*) - May not be necessary (???)

This demo nstrates the use of the reversible jump MCMC algorithm for neural networks. It uses a hierarchical full Bayesian model for neural networks. This model treats the model dimension (number of neurons), model parameters, regularisation parameters and noise parameters as random variables that need to be estimated. The derivations and proof of geometric convergence are presented, in detail, in: Christophe Andrieu, Nando de Freitas and Arnaud Doucet. Robust Full Bayesian Learning for Neural Networks. Technical report CUED/F-INFENG/TR 343, Cambridge University Department of Engineering, May 1999. After downloading the file, type "tar -xf rjMCMC.tar" to uncompress it. This creates the directory rjMCMC containing the required m files. Go to this directory, load matlab5 and type "rjdemo1". In the header of the demo file, one can Select to monitor the simulation progress (with par.doPlot=1) and modify the simulation parameters.
