Install windows 7 on macbook pro and how to get the required drivers

如何在Mac Book Pro 下安装Windows 7 和所需的驱动程序

2 days ago a friend of mine has bought a 13 inches Mac Book Pro.
How to install Windows 7 on Mac OS with Bootcamp 


How to obtain and install the drivers?

After installing the Windows 7, we found  it is difficult to get the required hardware driver for apple, as there is no drivers CD comes with Mac Book Pro. After calling the technical consultant, we found out, those drivers could be easily gotten from the Bootcamp  Utility preinstalled with Mac OS X.


Hold down the Option key during the starting of machine, you will be able to boot into Mac OS X. Open the Bootcamp Utility, you will discover there is an option to "Download the Latest Windows Support Software from Apple". Select that option, put a USB drive in, it will download all the necessary drivers to the USB drivers.

Then Boot to windows again, open USB drive, click "setup" in USB drive, and voila, All the required drivers will be installed!

Complete information could be found here

Antlr opened remote debugger instead of local debugger


Problem:
When running the Debug for Antlr, you see this following output message in Debugger Tab/Output Message

I looked around and found this:
java.lang.UnsupportedClassVersionError: __Test__ : Unsupported major.minor version 51.0
               at java.lang.ClassLoader.defineClass1(Native Method)
               at java.lang.ClassLoader.defineClassCond(Unknown Source)

               at java.lang.ClassLoader.loadClass(Unknown Source)
Could not find the main class: __Test__.  Program will exit.
Exception in thread "main" 

And it opened Remote Debugger instead of using local Debugger

Solution:
The problem that this occurred for me is due to several version of Java is installed in my machine.
e.g. java 1.6(x86) and java1.7(x64) i am using 64 bits machine.
I delete all the java version I have, and installed again java1.7, i works.

Originally in Help>About>Information tab, it shows java 1.6.
After unstalling and reinstall, it shows the correct version java 1.7.

Regular Expression

A good tool for leaning regular expression



    Self Summary
  1. Intro
  2. Word Boundary- \bA\w*\b match a word that starts with 'A'.
  3. \b denotes the word boundary(start and end of word). \b has zero length.
  4. Input Boundary - ^w*$ match a word if it is the only word. ^ and $ matched beginning and end of an input. Both have zero length.
  5. Repeat - \d{3} digit repeat for 3 times, \d{3,5} 3 to 5 times, \d{3,} at least 3 times
  6. Whitespace - \s any whitespace character
  7. Escape - escapes character \ for character ^  .  \   (   ) uses \^   \.  \\  \(  \) instead
  8. One of it - [abcde] any one character in the bracket
  9. none of it - [^abcde] no character in the bracket
  10. Greedy and lazy
  11. a.*b The longest string starting with a and ending with b
    a.*?b The shortest string starting with a and ending with b
  12. [.]* means ….
  13. but (.)* 12345




    Positive Matched
    \w
    Match any alphanumeric character
    .
    Match any character except newline
    \s
    Match any whitespace character
    \d
    Match any digit
    \b
    Match the beginning or end of a word
    \n
    newline
    ^
    Match the beginning of the string
    $
    Match the end of the s

    Negative Matched
    \W
    Match any character that is NOT alphanumeric
    \S
    Match any character that is NOT whitespace
    \D
    Match any character that is NOT a digit
    \B
    Match a position that is NOT the beginning or end of a word
    [^x]
    Match any character that is NOT x
    [^aeiou]
    Match any character that is NOT one of the characters aeiou

    Repeat
    *
    Repeat any number of times
    +
    Repeat one or more times
    ?
    Repeat zero or one time
    {n}
    Repeat n times
    {n,m}
    Repeat at least n, but no more than m times
    {n,}
    Repeat at least n times

    Greedy and lazy
    *?
    Repeat any number of times, but as few as possible
    +?
    Repeat one or more times, but as few as possible
    ??
    Repeat zero or one time, but as few as possible
    {n,m}?
    Repeat at least n, but no more than m times, but as few as possible
    {n,}?
    Repeat at least n times, but as few as possible


    Captures
     
    (exp)
    Match exp and capture it in an automatically numbered group
    (?<name>exp)
    Match exp and capture it in a group named name
    (?:exp)
    Match exp, but do not capture it
    Lookarounds
     
    (?=exp)
    Match any position before a suffix exp (ing below)(not including exp)
    Say \b\w+(?=ing\b) it matches any words ending with ing
    working abcing -> working abcing
    (purple is the matching one)

    (?<=exp)
    Match any position after prefix exp (re below)(including exp)
    Say (?<=\bre)\w+\b it matches any words starts with re
    reduction -> reduction
    (purple is the matching one)

    (?!exp)
    Match any position after which the suffix exp (123 below)  is not found

    work(?!123)
    work123->work1234 (no match)

    But,
    work1(?!123)
    work123 ->work1234

    Reason is for work1, it goes to
    work1|23, where it is follows by 23 instead of 123

    (?<!exp)
    Match any position before which the prefix exp is not found

    (?<!123)
    123work->123work (no match)

    But,
    (?<!123)3work
    123work->123work (no match)

    Reason is for 3work, it goes to
    12|3work, where it is prefix by 12 instead of 123



      Comment
    (?#comment)
    Comment

    Special Character

    opening square bracket [\[
    the backslash \\\
    the caret ^\^
    the dollar sign $, \$
    the period or dot .\.
    the vertical bar or pipe symbol |, \|
     the question mark ?, \?
     the asterisk or star *\*
    the plus sign +\+
    the opening round bracket ( and \(
    the closing round bracket ). \)




  14. About Replacement
  15. (?<named>pattern) denote a grouping with a name named
    (pattern) denote a grouping with No Name(refer by number)

    Named example
    strInput = Regex.Replace(strInput,"(?<first>abc)","def${first})
    Replace "abc" becomes "defabc"

    UnNamed Example
    strInput = Regex.Replace(strInput,"(abc)","def$(1))
    Replace "abc" becomes "defabc"

    Summary of symbol
    $& 
    matched text
    $_   
    original source string
    $` 
    text before match
    $' 
    text after match
    ${group_name}
    text matched by named group
    $1, $2   
    text matched by numbered group
    $$   
    the literal "$"


    Another example

    sResult = Regex.Replace("The price is 31.95","\d+\.\d{2}","$$$&")
    It Put $ in front of monetary values


  16. About Lookaround
  17. The advantage for lookaround is not including the word that matched.

  18.  Misc
  19. Match {…} where … not containing word hede
    {((?!hede)[^}])*}
