So today with 'A voyage to Kernel' again, it's been two days since i had read another volume of this. So today i need to rejunevate my determination to complete all the volumes

By the way, i am also decided and determined to learn php and javascript to my project list
Oh man, just now, i already wasted by surfing and reading about some stupid article, i am really addicted to this news stuff. I should get rid of this obsession or distraction whatever it is.
Come on you can do it.

Now before learning this , i should say something about the usage of vi editor

excellent to use: shortcuts are

Esc+ i     to insert  new text
Esc + :w                     to save a file
Esc + :w filename     to save a file with name
Esc + :q!                  quit without saving
Esc + :wq                  save and quit
Esc + yy                    to copy a line where the cursor is staying
Esc + dd                    delete the line the cursor is staying
Esc + wd                   delete the word from the cursors position
Esc + /word               search a specific word
n                                 to continue with search

the main stuff of this experiment will be in the next post, goodbye for now
