i have installed octave 3.6 version on macbook. uses emacs default editor, seems regular emacs keys (such c-x c-c exiting) doesn't work in octave emacs. also, output buffer gets messed when try use octave. also, prints prompt when i'm in emacs. (see picture below) it seems it's parsing input in editor on fly. have no idea how every happen. can tell me problem , how fix it? my guess end running emacs comes bundled mac os x (an old version of emacs works in text mode) , want change installing more recent version can run in gui. that's wild guess.

i've tried searching around , can't find answer makes sense. basically when activity first starts should connect server , continually listen message. when gets it, it'll parse , if it's particular message, close connection , other stuff. should able close if user pushes button. i tried searching around , can't tell if should use servlets or services or (edit: or how use them). know needs on it's own thread. so should use? edit: i'm not sure how use servers/services/etc. make happen an intentservice you're gonna want. it's easiest implement , it's perfect network operations. automatically handles running service in own thread. once establish connection server, should stay open until respond message server.
