php - Timer Concept on Server Side -


here's scenario:

i have smartfox server running on amazon ec2 , using mysql database. i'm using as3 programming language.

i have virtual world in user can click on icon (like home design), , shows animation house getting built. takes 8 hours build , show percentage progress bar it's getting build.

i have used as3 timers, problem user might log out virtual world (or close browser) , come @ later (after maybe 2 8 hours, instance).

i haven't done before, can me details, such general strategy needs used , how implement, etc.

please help.

you - right after user clicks , starts process notify server , make server side script current time , save db. if user logs out right after that, retrieve saved timestamp each time client app starts again , calculate how time passed since timestamp taken (at server side), pass calculated value client. way have right time displayed , calculations client internal clock independent.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
