RTC Concept

Concept
Repozitory : The repository includes auditable item types, which maintain a history of item creation and subsequent modifications for audit purposes. The audit trail includes a record of past states of the item, the user who saved the item, and the time of the change. For item types that do not require audit history, the repository retains only the latest state of the item.
Project Area : The project area is a system representation of a software project. The project area defines the project deliverables, team structure, process, and schedule. A project area is stored as a top-level or root item in a repository. A project area references project artifacts and stores the relationships between these artifacts.

Python - a study note

Reference : http://www.rexx.com/~dkuhlman/python_book_01.html

• Naming
• Allowed characters in a name: a-z A-Z 0-9 underscore, and must begin with a letter or underscore.
• Names and identifiers are case sensitive.
• Identifiers can be of unlimited length.Special names, customizing, etc. -- Usually begin and end in double underscores.
• Special name classes -- Single and double underscores.
  • Leading double underscores -- Name mangling for method names.
  • Leading single underscore -- Suggests a "private" method name in a class. Not imported by "from module import *".
  • Trailing single underscore -- Sometimes used to avoid a conflict with a keyword, for example, class_.
• Naming conventions -- Not rigid, but here is one set of recommendations:
• Modules and packages -- all lower case.
• Globals and constants -- Upper case.
• Class names -- Bumpy caps with initial upper.
• Method and function names -- All lower case with words separated by underscores.
• Local variables -- Lower case (possibly with underscore between words) or bumpy caps with initial lower or your choice.
• No declaration or data type definition is needed/used.
• Block
• Python represents block structure and nested block structure with indentation, not with begin and end brackets
• The statements which go together must have the same indentation. Each such set of statements is called a block.
• The empty block -- Use the pass no-op statement.
• DocStrings : A doc string is a quoted string at the beginning of a module, function, class, or method.We can use triple-quoting to create doc strings that span multiple lines.
• Doc strings can be viewed with several tools, e.g. help(),obj.__doc__, and, in IPython, a question mark (?) after a name will produce help.
• Statement
• while running:
      guess = int(raw_input('Enter an integer : '))
      if guess == number:
         print 'Congratulations, you guessed it.'
         running = False # this causes the while loop to stop
      elif guess < number:
         print 'No, it is a little higher than that.'
         continue
      else:
         print 'No, it is a little lower than that.'
         break
  else:
      print 'The while loop is over.'
  # Do anything else you want to do here
  print 'Done'
• for i in range(1, 5):
     print i
  else:
     print 'The for loop is over'

Replace framework.jar on Android Emulator

1. Start up Emulator
  $ cd {ANDROID SDK}/tools
  $ ./emulator -avd {AVD_NAME}
2. Use adb shell to set rw access right on /system
  $ ./adb shell
  # mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system

  # cat sh > su
  # chmod 4755 su
  # exit
3. upload framework.jar to target directory
  $ ./adb push
 {MYDONUT_OUT_PATH}/target/product/generic/system/framework/framework.jar /system/framework
4. restart Emulator
  $ ./adb shell
  # stop
  # start
