i'm studying javascript, , found example on book function saynameforall(label) { console.log(label + ":" + this.name); } var person1 = { name: "nicholas" }; var person2 = { name: "greg" }; var name = "michael"; saynameforall.call(this, "global"); saynameforall.call(person1, "person1"); saynameforall.call(person2, "person2"); this outputs: "global:michael" "person1:nicholas" "person2:greg" i understand how call works, output of saynameforall.call(this, "global"); isn't global:michael global:result . this code http://jsfiddle.net/rho3zyb4/ you're running code in jsfiddle, aren't you: http://jsfiddle.net/4g8q9yor/ - jsfiddle has assigned iframe name javascript outputs result - you're getting dom iframe name. create file on local machine , you'll see correct output or try elsewhere: http://js.do/code/48143 output...

i have json data array this: var data=[ {"someproperty":"number","time":"2014-12-11t09:24:39.000z"}, {"someproperty":"number","time":"2014-12-11t09:27:39.000z"}, {"someproperty":"number","time":"2014-12-11t09:30:39.000z"}, ..... ] i need draw circle each 1 in array (with radius of "someproperty") , put them in analog clock according time. found picture similar problem here: but no code :( i use d3.js it. succeeded in doing using rotate circles on circumference , intersect each other. want put them across radius in order avoid collision. see examples of collision detection http://bl.ocks.org/mbostock/1747543 don't see there option control x,y position want. if read question right, "someproperty" provide radius value, , "time" provides angle. i suggest transforming these datum polar coordnates described her...

this question has answer here: why isn't qualified static final variable allowed in static initialization block? 2 answers for example, consider code snap below: public static final int a; public static final int b; static { = 8; // it's working test.b = 10; // compilation error test.b cannot assigned. } why can't use test.b = 10; inside static block of test class itself? without class name it's working fine. is there reason behind this? a static final variable must initialized before use. may initialized either directly @ declaration time, or in static block. but when use class.var = x not seen initialization assignation. with jdk 7, error cannot assign value final variable . that explains why works if remove final keyword class test { static final int = 2; // initialization @ declaration time stati...

related, not answer question: how modify install name of .dylib @ build time on osx, have dynamic library provided packager manager, installed in non standard directory, install_name filename. example: $ root=$pwd $ mkdir $root/foo $ cd $root/foo $ echo 'int foo(int a, int b){return a+b;}' > foo.c $ clang foo.c -dynamiclib -install_name libfoo.dylib -o libfoo.dylib i don't want change (absolute path, @rpath, ...) install_name of libfoo.dylib using install_name_tool -id . now link program library, example: $ mkdir $root/bar $ cd $root/bar $ echo 'int foo(int,int); int main(){return foo(2,4);}' > main.c $ clang main.c -l../foo -lfoo the program can't run: $ ./a.out dyld: library not loaded: libfoo.dylib referenced from: $root/bar/./a.out reason: image not found trace/bpt trap: 5 because: $ otool -l ./a.out ./a.out: libfoo.dylib (compatibility version 0.0.0, current version 0.0.0) /usr/lib/libsystem.b.dylib (...

i trying using roslyn extract various method call information give source file. elaborate - want find method invocations happen inside input file. one problem hitting extension methods. consider linq method aggregate , sum etc. how can figure out invocationexpressionsyntax method being invoked extension method , not simple member method of class. the source file input can expected compile - meaning getdiagnostics() not have errors. ---- code property mentioned @kevin in answer ---- var methodinfo = model.getsymbolinfo(invocation); if (methodinfo.symbol != null) { var msymbol = (imethodsymbol)methodinfo.symbol; if (msymbol.reducedfrom != null) { // extension method ! } } you can find actual static extension method instance invocation of extension method using imethodsymbol.reducedfrom property.
