javascript - <script> src replacement - sandbox breaker - will it last? -

-

hey people, working on web do-dad allows has embed code.

in particular embed, iframe added page in place of embed code via javascript. have control of user's page, and, since writing content of iframe javascript well, control of iframed page. doing (as opposed sourcing iframe our server) lets talk iframe cool trick.

the problem: iframed page still needs ajax stuff our server. sandbox issues! solution, seemed me <script> src replacement - replacing our ajax procedure sandbox-breaker version.

i have been told ability of browsers on chopping block. true? terrible! can't find anythign effect in (admittedly brief) research, , though i'd go experts

  • is <script> src replacement viable mechanism pull off sandbox-breaker type effects?
  • is <script> src replacement viable @ all?
  • how adwords work? need call home, right? how that?
  • i understand soon-to-be available cross site xhr stuff pop security dialogs - true?
  • can recommend , other sandbox breaker technique won't pop security dialog?

(yes aware of security concerns - wearing protection , whatnot)

thanks!

is src replacement viable mechanism pull off sandbox-breaker type effects?

yes

is src replacement viable @ all?

yes. original ajax.

how adwords work? need call home, right? how that?

adwords based on screen-scrape of site. context-related. ajax content not scraped unless know how use url hash techniques.

i understand soon-to-be available cross site xhr stuff pop security dialogs - true?

the hosting page need explicitly allow this, yes.

can reccomend , other sandbox breaker technique won't pop security dialog?

use flash.

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
