what value of this in javascript generators in javascript? in below code, both comparisons return false, , when .tosource() , this appears empty object . references ecma or mdn docs helpful, wasn't able find in either. function thisgenerator(){ while(1) yield this; } var gen=new thisgenerator(); alert(gen.next()==thisgenerator); alert(gen.next()==gen); this still obeys normal rules. considering, global scope window : var gen = (function() { yield this; })(); gen.next() === window // true var gen = (function() { "use strict"; yield this; })(); gen.next() === undefined // true in quirks mode, this in unbound functions global scope (which happens window ), while in strict mode undefined . ps: when calling function bound, still usual: var o = { foo: function() { yield this; } }; o.foo().next() === o // true var o = {}; function foo() { yield this; }; foo.call(o).next() === o // true

it's possible assign :nth-child specific element, without count other element in middle (ex http://jsfiddle.net/mgc4v/ <*br>). <p>1</p> <br> <p>2</p> <p>3</p> p:nth-child(3) { background-color:red; } the red line second one, not third..thanks p:nth-of-type(3) { background-color:red; } will select third <p> element :) , question ? see http://www.w3.org/wiki/css/selectors/pseudo-classes/:nth-of-type example : http://codepen.io/anon/pen/dxgos

i encountered strange issue. don't understand why code doesn't work: public static <type1 extends integer, type2 extends double > object addition(type1 first, type2 second) { return second * first; } the compiler claims operator * cannot applied type2,type1 . types extends integer , double has + operator defined them. don't understand this you wrong. neither integer nor double or other objects extending number class have "+" or other operator definied. reason why able perform (integer + double) autoboxing. , autoboxing kind of "hardcoded" feature applies small predefined set of classes, such integer, double, etc. furthermore, integer , other number subclasses declared "final", therefore "type extends integer" has no meaning, since cannot extend integer.

i trying familiarized three.js , came across strange can't quite wrap head around. in other systems, (non web based), i've used, lighting normal maps calculated in tangent space. in three.js things bit different. example, if consider code in webglshaders.js @ line 2643: "mat3 tsb = mat3( normalize( vtangent ), normalize( vbinormal ), normalize( vnormal ) );", "vec3 finalnormal = tsb * normaltex;", they set orthonormal basis matrix tangent space, , transform normal space. far good. the issue is... seems place transform vectors tangent space??? so light direction vector calculate not converted tangent space, , neither eye direction vector??? both of subsequently used calculate lighting on lines 2692-2694: "vec3 pointhalfvector = normalize( pointvector + viewposition );", "float pointdotnormalhalf = max( dot( normal, pointhalfvector ), 0.0 );", "float pointspecularweight = speculartex.r * max( pow( pointdotnormalhalf,

1.i'm implementing sdk using android remote service. 2.in order distribute sdk,i'd many apps integrate sdk be. 3.in order save system resources, i'd 1 process of remote service running in background support apps need remote-service. is there way achieve this? thanks. you write resource locking mechanism. if you're handling call app a, , app b wants same call, return error code isn't fatal, rather tells app try @ time. or create queue callback app b fires when app done.

i trying add , use font within app. i've followed post reference can't work. i've added font frutiger95ultrablack.ttf supporting file , added {app-name}-info.plist. then tried use in app delegate change uinavegationbar nothing happens. what missing??

is there way control each step of tcp socket write know server side progress of large sized image data transfer? at worst, how alter main node bin folder add event? finally, can explain me why max length of node.js http tcp sockets 1460? from documentation : socket.write(data, [encoding], [callback]) sends data on socket. second parameter specifies encoding in case of string--it defaults utf8 encoding. returns true if entire data flushed kernel buffer. returns false if or part of data queued in user memory. 'drain' emitted when buffer again free. the optional callback parameter executed when data written out - may not immediately. event: 'drain' emitted when write buffer becomes empty. can used throttle uploads. see also: return values of socket.write() so, can either specify callback called once data flushed, or can register "drain" event handler on socket. doesn't tell progress on o

i want generate url browse directly artifact. i can browse specific repository following url. https://repository.sonatype.org/index.html#view-repositories;maven-sites~browsestorage is possible browse specific item single url? e.g. in above repository there artifact called nexus-oss/css. have url directly expand tree in browsestorage view artifact nexus-oss/css. thx derek you can browse directly, afaik not using nexus ui. example: https://repository.sonatype.org/content/sites/maven-sites/nexus-oss/css/ if there url this, reckon this: https://repository.sonatype.org/index.html#view-repositories;maven-sites~browsestorage~/nexus-oss/css/maven-base.css since url when select specific artifact , click "contained in repositories" link.
