now of course, code make do. but i'm confused why in following code: var = { 0: "hi", 1: "bye" } (var b in a) { settimeout(function () { console.log(b); }, 1000); } instead of consoling "0" , "1" i "1" twice. i'm not sure why happens. need setup script making same issue. it because usage of closure wrong. in case using closure variable b inside settimeout callback, value of variable b not looked until callback executed, value of updated last value in object. one of solution in such case create local closure given below for (var b in a) { (function(c){ settimeout(function () { console.log(c); }, 1000); })(b) } demo: fiddle

is possible make object immutable in v8 javascript engine? v8 embedded in c++ application. in case i've created , populated array (code simplified) auto arr = v8::array::new(isolate, 10); (auto = 0; < 10; ++i) { arr->set(context, i, v8::integer::new(isolate, i)); } i'd make resulting object "read-only" (as might calling object.freeze ) before passing script. 1 of script authors got in confusing situation trying re-use object convoluted way, , i'd make harder happen making object immutable. i understand can in javascript ( object.freeze ), able in c++ if possible. this approach works, although it's little inelegant. essentially, i'm calling "object.freeze" directly in javascript, couldn't find way invoke functionality c++. i'm less fluent in v8, code may unnecessarily verbose. /** * make object immutable calling "object.freeze". * https://developer.mozilla.org/en-us/docs/web/javascript/reference...

i developing game using lwjgl 3.0.0b , strange occurrence has come up. background: i have custom entity class , entity manager store entities in. when entity updated method gets called named " ticktrail " adds in trail entity make graphics visually better , entertaining. already have simplified down entities.size() function, yes try solve myself :p a solution have replacing methods similar this: for (int = 0; < entities.size(); i++) { //calls method drawing, updating, or input } to replace every single entities.size() size . size being variable changed upon when entity added, removed, list cleared, or enemies removed. this method work 100%, window dragging not crash program using method. question so sum up, final question why occur? haven't determined why dragging window , using arraylist's size() method crashes program, yet storing variable in place fine. any or explanation strange phenomenon highly appreciated :) edit last edit pro...

i have double array in mappartition of rdd,and when declare iterator or densematrix double array.i found iterator , matrix empty.my test codes below: val randxts = data.map{ line => val fields = patterns.findallin(line).toarray.map(_.todouble) fields(fields.length-1) }.repartition(2) val res = randxts.mappartitions(x=>{ val matrix = new densematrix(x.length,1,x.toarray) val arr = matrix.toarray println(k.length) (matrix::list[densematrix[double]]()).iterator }) as shown above,the line declare matrix cause error.the error message below: java.lang.indexoutofboundsexception: storage array has size 0 indices can grow large 124 how can fix problem? your code calls x.length , passes x again densematrix constructor. since x iterator, calling length "consumes" iterator, hence passing again result in empty collection. to fix - scan iterator once (by converting array): val res: rdd[densematrix] = randxts.mappartitions(x => { val arr = x.to...
