It's also new in vision field..
Hopefully I can use it in the next step work.
If it's true,,,Then we store information in the wave frequency type in our brain..The brain cells are different just because they are just stimuli by the certain frequency. The information was transform from space-time to frequency field.
For example, in vision work, the information of the object is holograph image on the front of eyes. But after project by our eye lens , it becomes 2D image on our retina .But the image is not saved directly in the brain, before it is restored , it will be transformed again to holograph.. The brain save this holograph of the object in the certain field ..
If it's true, it will be easy understood that some guys can feel other guys' feeling or can communicated with each other by special wave or other things like that;
But some guys think it's Pseudoscience .not theroy.because there are no enough evidence to support that..

She works with me..I am very happy that I can learn so much from her as she graduated from computer science...
She know much program skill that I need.
I learn how to use doxygen to document my code .
That will make my program more beautiful and easy to understand.
As I use suse Linux , it has installed doxygen, so I don't need to install it again.
1,comment you file.
If this file is .cpp or .h, you need add /*! \file "file's name"*/ to this headfile or source code file. If you don't do that ,you can't document it;
if you want to document some variable, you just need add /*!<"some comment"*/ after this variable.
you can use /def + macro name to document the definition of macro.
you can use /param or@param + [in/out]+"parameter's name" to document the function's document;
As in my head file, I will do this before a function:
//! "short comment about function"
@param[in] "parameter comments"
you can use \fn to document a function, but you need write the function again. If you change function 's name or parameters , you also need remember to change the comment.so it's not convenient;
2,build configure file and html file
doxygen -g <your configure file's name which contain many setting informations. you can give a name or nothing.if nothing, then doxygen will build Doxygen file in present directory>
doxygen <configure file name>
then you can see html file in your directory.
open it and use firefox or other web browser to see it...
you will find your code is so beautiful....
I really enjoy it..

1,use vi or other edit tool to build a empty file
2,write your signature in it and save it in any directory. It should be best to save it in .txt file.
3,open your thunderbird and do edit/Account Settings, you will see add signature file. Then you can add the txt file.
4,when you build a new email, you will see you signature now...
