on 1 of scripts have code: var websocket = window.websocket || window.mozwebsocket; window.ws = new websocket('ws://64.121.210.140:2585/consoleappsample', 'my-protocol'); which works fine. however, when user changes pages, have re-establish connection. believe causing problems in code because if client sends data server , changes pages, data may not received , race conditions occurring. i tried put window.ws in global scope didn't seem fix problem. there way websockets connection persist between pages connection not need reestablished? the global scope mentioned related javascript context, , context created each windows (and destroyed when document unloaded memory). therefore, effort useless: can't keep connection opened if user change page. of course can have webapp "single page" application, data loaded using xmlhttprequest / ajax / websocket. so, leaving page means leaving / shutdown application, , makes sense close socket. ano...

im working in zsh, im sure bash instructions also. need have loop goes thru values stored in array lw , launches shell script, based on name stored in array. so far, i've come with: $lw=('plugin1' 'plugin2' 'plugin3') in $lw; . ~/library/rogall/plugins/$lw[$i]/lw.prg end; done it gives me error when run saying can't find ~/library/rogall/plugins//lw.prg, appears ignoring variable togethor. any ideas i've messed up? it's simpler that: lw=('plugin1' 'plugin2' 'plugin3') in $lw; . ~/library/rogall/plugins/$i/lw.prg end done in summary: assign "foo", not "$foo" (the shell try expand $foo , assign whatever expands to; typically not useful) use loop variable directly; contains array value rather index

i wanna make program on bézier surfaces, found on internet this article , there 1 approach how it, don't understand second step , third step particularly. or may cant imagine author can mean that. b. use blending tables calculate points in "row curve": for( u = 0; u < 10; u++ ) { blend row 0 control points -> new control point blend row 1 control points -> new control point blend row 2 control points -> new control point blend row 3 control points -> new control point for( v = 0; v < 10; v++ ) { blend 4 new control points -> point on surface } } c. generate edges , polygons grid of surface points. can explain mean? thx. a bezier-surface bezier-curve, control-points moving along other bezier-curves, instead of being stationary. b(0,u) = (1-u)^3 b(1,u) = 3*u*(1-u)^2 b(2,u) = 3*u^2*(1-u) b(3,u) = u^3 c[0..3, 0..3] = control points curve(t,c0,c1,c2,c3) = b(0,t)*c0 + b(1,t)*c1 + b(2,t)*c2 + b(3,t)*...

clang 3.1 claims support user defined literals. can define this: int operator"" _tryit(long double n) { return int(n); } but when try use error: int m = 5_tryit; invalid suffix '_tryit' on integer constant 5 cannot implicitly converted long double in case. need change 5.0 make long double or explicitly invoke function implicit conversion work: int m = 5.0_tryit; or int n = operator"" _tryit(5); (tested both clang version 3.1 (trunk) (llvm/trunk 155821) ) this question has explanation of rules. (also, abarnert mentions, make sure passing -std=c++11 flag compiler when compiling).
