Installation for Shiro Plugin on Grails

Installation

1. grails create-project shiroPluginTest
2. cd shiroPluginTest
3. grails install-plugin shiro
4. grails shiro-quick-start --prefix="Sec"
   automatically create : domain/SecUser, domain/SecRole, controller/AuthController , Config/ShiroSecurityFilter
5. insert some data into Project. edit "Config/Bootstrap.groovy"
   Bootstrap.groovy

   class BootStrap {     def init = { servletContext ->         def u1 = new SecUser(username: 'user', passwordHash: new Sha1Hash('user').toHex())         u1.save()         def u2 = new SecUser(username: 'admin', passwordHash: new Sha1Hash('admin').toHex())         u2.save()         def role= new SecRole(name:'user').addToUsers(u1)         role.addToPermissions("*:*")         role.save()         def role2= new SecRole(name:'admin').addToUsers(u2)         role2.addToPermissions("*:*")         role2.save()     }     def destroy = {     } }

6. grails create-controller shiroTest
7. grails generate-views shiroTest
8. grails run-app
9. try to go to any page, and see the login page is work correct

install the LDAP server

........(still working)

Installation of MongoDB

Introduction

MongoDB (from "humongous") is a scalable, high-performance, open source, document-oriented database. Written in C++.

Installation

1. download it in here (depend on your platform)
2. unzip it into a folder. example : c:\mongodb\
3. create the database file path. example : c:\mongodb\data\
4. execute the mongodb. c:\mongodb\bin\mongod --dbpath=c:\mongodb\data\
5. the mongodb will open at port 27017(data connection) and 28017(control panel)
6. open the browser and enter the URL( http://localhost:28017 , and see the result as follow :

Extension - Master and Slave Structure

Concept(working)

we setting the Master/Slave structure in local computer.

1. create the database file paths : c:\mongod\master_data\, c:\mongod\slave_data1\, c:\mongod\slave_data2\
2. start the master : c:\mongodb\bin\mongod --master --dbpath=c:\mongod\master_data\ --port 10000
3. start the slave1 : c:\mongodb\bin\mongod --slave --source localhost:10000 --dbpath=c:\mongod\slave_data1\ --port 20000
4. start the slave2 : c:\mongodb\bin\mongod --slave --source localhost:10000 --dbpath=c:\mongod\slave_data2\ --port 30000
5. done

MongoDB on Grails

Installation

1. grails create-app mongodbTest
2. grails install-plugin mongodb-morphia
3. add data source
   grails-app/conf/DataSource.groovy

   mongodb {   host = 'localhost'   port = 27017   databaseName = 'test'   username = "YOUR_USERNAME"   password = "YOUR_PASSWORD" } }

4. grails create-mongodb-class Car
5. add some attributes for db-class
   grails-app/mongo/Car.groovy

   class Car{     String brand     String title }

6. grails generate-all Car
7. grails run-app (make sure the mongodb is open)
8. add some data by browser
9. done

smaf to wav solution

Survey

midi -> smaf(mmf,spf) -> wav

1. midi-> smaf(mmf) : RetroCode<support MA2,3,5>
2. smaf-> wav :

• recorder software : total recorder, mp3mymp3(free), Audacity(free)
  • how to convert MMF to WAV
• auto-play script : sikuli
  
  figure. the sikuli script
• recording by python api : pyaudio
  recorder.py

  import pyaudio import wave p = pyaudio.PyAudio() stream = p.open(format = FORMAT,                 channels = CHANNELS,                 rate = RATE,                 input = True)                 #frames_per_buffer = chunk) print "* recording" all = [] for i in range(0, RATE / chunk * RECORD_SECONDS):     data = stream.read(chunk)     all.append(data) print "* done recording"

Final version

System structure

Step by step

1. open stereo mode

figure. setting stereo mix mode on Windows 7

hint the option is hidden on Windows 7

2. open recorder(server)

• make sure the softwares
  • python 2.7
  • pyaduio
• execution server
  • command line : #python server_recorder.py
  • IDEL : execfile("C:\server_recorder.py")

3. open player(client)

• open mexa emulator
• create folder /sampleData/jscl_storage_root/mc/(the StorageConnection use)
• copy smaf music in /sampleData/jscl_storage_root/mc/MEXA/*.spf
• running MIDlet

4. collection data
you can see the wav file in Default path - C:\Python27\smaf2wav\
