javascript - How "best" to allow a web-page visitor to construct mathematical or statistical tools? -

-

i have free web site streams real-time stock-options data. want let users make , save own javascript-callable tools interpret options data. users can invoke these custom tools them make own sell/buy decisions options.

but totally stopped, stymied, dead-ended, , buffaloed how accomplish this. if there few choices, guess stumble around blindfolded (as now) , hit on 1 kind-of worked.

but choices seem endless:

  1. let user write javascript tools i'd interpret;
  2. mathematica , toolsets;
  3. many statistics packages;
  4. google spreadsheet api.

and overwhelmingly many more.

if has struggled through process of giving user facility making statistics , probability tools, how did end up? , way again?

plus, feature-creeposis , perfectionitis want me integrate charts, graphs, heat maps, , knows else more; or @ least allow later integration of graphics.

graphics nice , sexy: i'd drop , graphics. have resist , something onto page real now.1

q: can/should allow , encourage easy, intuitive, secure, , powerful tool construction?

edit: don't mean want invent whole new system de novo. (uh-huh, yeah, that's right; 'only' :-) want interface already-existing javascript-callable package.

thanks much!

1 know little bit of how employers might have felt me @ 1 time: "aw, c'mahhhhhhhhhn, feature sexy leave out."

if need out door quickly, first best stop-gap solution give people ability export data tool know how use (e.g., excel) purpose. worry own version of wheel once you've provided basic short-term solution.

of course, that's not marginalize topic of building functional, browser-based statistical analysis package, seems interesting. honest might come , post "hey guys, need develop new operating system iphone. ideas?" ;)

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...
