i getting timestamp every time key pressed this: init_timestamp = time.time() while (true): c = getch() offset = time.time() - init_timestamp print("%s,%s" % (c,offset), file=f) ( getch answer ). i verifying timestamps against audio recording of me typing keys. after lining first timestamp waveform, subsequent timestamps drift slighty consistently. mean saved timestamps later keypress waveforms , later , later time goes on. i reasonably sure waveform timing correct (i.e. recording not fast or slow), because in recording included ticking of accurate clock lines second markers. i aware there unavoidable limits accuracy of time.time() , not seem account i'm seeing - if equally wrong on both sides acceptable, not want gradually diverge more , more truth. why seeing drifting behaviour , can avoid it? just solved using time.monotonic() instead of time.time() . time.time() seems use gettimeofday ( at least here does ) apparently bad measu...

my server running on os ubuntu 10.4 . when run command "skype -callto userid" makes call using skype user interface. but when run same command connecting via ssh or java code runtime.getruntime().exec(command) , not working. what reason of such behavior? i guess problem skype needs x server run properly. enable x11 forwarding. x11 forwarding needs configured on client , server side: on server side enable x11 forwarding setting x11forwarding yes in /etc/ssh/sshd_config , restarting ssh service service sshd restart . might need install xauth on server side. on client side need open ssh connection -x parameter enable x11 forwarding session.

what difference between two? me both doing same thing i.e notify event observer event. i read post http://www.raywenderlich.com/46988/ios-design-patterns regarding actual pattern in use 2 above mentioned event handling techniques failed understand how command pattern different observer pattern or missing something. my understanding of them next: in case of target action, have notification center through pass info between 2 classes. have 1 class sends out notification notification center broadcast info , second class has observers listen broadcast matches criteria. while in case of kvo have object capable of observing change of 1 of it's properties. no 1 posting notification in case of kvo. hope cleared things @ least bit.
