Win7 x64: Chinese Hand Writing applet is missing in IME Pad

 

I'm using a Windows 7 x64 OS. As shown in the screenshot above, there is no Chinese Hand Writing applet for some reasons, so I have been using the Japanese one as a workaround...

Today, I finally decided to look into it. Surprisingly, I'm not alone. And luckily, Chris Wong has found a solution for us!

Solution:

1. Remove all Chinese keyboard

2. Open the Start menu

3. Type cmd -> Right click -> Run as administrator

4. Run the following command:

regsvr32 c:\Windows\System32\IME\IMETC10\applets\IMTCCAC.dll

5. Restart the computer

6. Add the Chinese (Traditional) - New Phonetic keyboard

7. Launch the IME Pad

8. Click on the app icon on the title bar -> Applet Menu -> Users Settings...

9. Hand Writing (CH) should now be available

Git: Change the author info in your repository's history

Warning:
This action is destructive to your repository's history. It's best to do this on a clone, just in case. Also beware that this should not be performed on a repository that has been shared with others. Use at your own risk.

1. create a shell script in your repository, e.g gistfile1.sh
2. copy the following code

#!/bin/sh

git filter-branch --env-filter '

an="$GIT_AUTHOR_NAME"
am="$GIT_AUTHOR_EMAIL"
cn="$GIT_COMMITTER_NAME"
cm="$GIT_COMMITTER_EMAIL"

if [ "$GIT_COMMITTER_EMAIL" = "your@email.to.match" ]
then
    cn="Your New Committer Name"
    cm="Your New Committer Email"
fi
if [ "$GIT_AUTHOR_EMAIL" = "your@email.to.match" ]
then
    an="Your New Author Name"
    am="Your New Author Email"
fi

export GIT_AUTHOR_NAME="$an"
export GIT_AUTHOR_EMAIL="$am"
export GIT_COMMITTER_NAME="$cn"
export GIT_COMMITTER_EMAIL="$cm"
'

3. modify the names and emails to the appropriate values
4. execute the script
