Thanks for all the suggestions. I do not really need an IDE 
actually. I used plain vi most of the time for text editing 
before this Ubuntu trial. Now I use simple gedit most often :(.
I like Ultraedit on Windows so maybe I would like to find 
some similar editor in Linux. I will learn more about vim/gvim.

I would like to learn more about make. It is good for me to 
understand more in order to understand other people's program.

I guess I will forget about Mplab/MCC18 first and start from the
basic like gputil and gpsim.
