i trying update reducer state using : store.dispatch(nameofthereducer(data)). it calls action creator not update reducer state. dont want create react component want dispatch state change. there way so..thanks in advance i think misunderstood how component , redux state relates. redux state change done through actions regardless of component 'using' state. as long have action creator defined somewhere, , reducer handle corresponding action.type , can use action creator in whichever component. there no benefit of using store directly. store stored in context , , considered bad practice using context . nice thing redux takes care of giving provider , connect . except when initializing app, should use mapdispatchtoprops when want use action creators in component.

i have system basicly poker server made c# + pubnub api. old source , improving code. don't know if system big system or home games purpose, don't sqlite poker server, reason is: make signup system, website read database data , things new , past tournaments, new , past cash games, new , past freerolls. thinking: free/opensource/creative commons or "freedom" database system can use? i asking choose , fast database system can implement , use long time. thank you if work microsoft's stack why not use ms sql server express? suppose, feet needs, , it's free. if going deploy server on hosting, migration ms sql server express ms sql server easy.

i attempting to change properties on caemitterlayer instance dynamically. making call setvalue:forkey: this: [self.mainviewcontroller.mainview.spaceview.emitterlayer setvalue:[nsnumber numberwithfloat:0] forkey:@"emittercells.particle.velocityrange"]; not seeing change in particle emitter. if set property 0 hard coding no particles emitted. here link gist file containing uiview implements particle system. know kvc can tricky miss typing maybe i'm over-looking obvious? so maybe i'm over-looking obvious indeed. problem line: setvalue:[nsnumber numberwithfloat:0] forkey:@"emittercells.particle.velocityrange" the string "emittercells.particle.velocityrange" not key. it key path . need call setvalue:forkeypath: .

i'm trying write code removes movies arraylist , blanking can stuff more movies later. i'll start code: for(int index = 0; index < movies.size(); index++){ removemovie(movies, movies.get(index)); } everytime loop runs, increment index , movies.size() should decrease. need keep movies.size() consistent while still representing original arraylist size. so, want "index < arraylistsoriginalsizehereeventhoughmyforloopisdecreasingitssizebyremovingmovies" here's tried now: int tempmoviesize = movies.size(); for(int index = 0; index < tempmoviesize; index++){ removemovie(movies, movies.get(index)); tempmoviesize += 1; } this doesn't work though because getting outofbounds exception. should maintain size of tempmoviesize . (it goes down 1 because movie object removed, , incremented one, canceling out , keeping @ original value (in case 8).) int size = movies.siz

i need each thread of warp deciding on setting or not respective bit in 32 bits word. multiple setting take 1 memory access, or 1 memory access each bit set? there no independent bit-setting capability in cuda. (there bit-field-insert instruction in ptx, nevertheless operates on 32-bit quantity.) each thread set bit doing full 32-bit write. such write need atomic rmw operation in order preserve other bits. therefore accesses serialized, @ whatever throughput of atomics are. if memory space not concern, breaking bits out separate integers allow avoid atomics. a 32-bit packed quantity assembled using __ballot() warp vote function . example given in answer here . (in fact, warp vote function may allow avoid memory transactions altogether; can handled in registers, if result need 32-bit packed quantity.)

js code is: this.sound1 ="global"; function cat(){ this.sound = 'meawo!!!!'; this.sound1 = 'meawooooo!!!!'; meawo1 = function(){ console.log(this.sound1); console.log(this); }; function meawo2(){ console.log(this.sound1); console.log(this); }; this.meawo = function(){ console.log(this.sound); console.log(this); meawo1(); meawo2(); }; }; var c = new cat(); c.meawo(); output is: question: how come this inside of meawo1 (function expression) & meawo2 (function expression declaration) referring "global" , not object c ? why that? always remember simple tip while wanting know object this refer to. obj.method(); in above, method 's called on obj , , hence this in method it's called on, i.e obj = this . in case, though meowo called on c , meowo1 , meowo2 aren't on object want refer to. functions don'

in web application i'm using jsf , primefaces. on buttons have time consuming functions. during time want show loading animation until complete site built. i'm doing calling functions showloading() , hideloading() this: <p:commandlink oncomplete="hideloading();" onstart="showloading()" process="@form" update="@form" actionlistener="#{dummycontroller.dummymethod}" content </p:commandlink> inside functions i'm showing/hidings div-objects specified id: function showloading() { $("#loader").show(); } this works fine. want show loading animation if pages needs more second build. that's why modified functions this: function showloading() { $(#loader").delay(1000).show(0); } function hideloading() { $("#loader").clearqueue(); $("#loader").hide(); } my problem @ point: loader works fine, in case doesn't appear. suggestion: showloading called @ diffe
