c# - Google Maps DOS attack -


we're using google's geocoding service on our website allow users enter zip code , find nearby locations. we've been having problem exceeding request limit of 25,000 per day (for 90 consecutive days). shouldn't getting traffic , i've found, when enabling logging, got 133 requests in 35 minutes. seems way much. i'm suspecting kind of scripted attack. can verify & prevent it?

i ended reading through api docs again , finding should've been coded geocoding request occurs on client-side. updated our pages use client script make geocoding request. way if user wants abuse it, blocked, not server. client script sends page lat , long coordinates needed , goes there without having interface google on server side.

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...
