visual studio's fread "locks out other threads." there alternate version _fread_nolock, reads "without locking other threads", should used "in thread-safe contexts such single-threaded applications or calling scope handles thread isolation." even after reading other relevant discussions on two, i'm confused if locking fread implements on specific file struct, specific actual file, or on fread calls on totally different files. if use nolock versions, level of locking need provide? can multiple threads in parallel reading separate files without locking? can multiple threads in parallel writing separate files without locking? or there global or static variables involved corrupted? so, using nolock versions, able potentially achieve better i/o throughput (if aren't needlessly moving heads, reading off separate drives, or ssd drive), or potential gain reducing redundant locks single lock (which should negligible.) does vs' ifstre...

i'm trying create throttling queue of sorts in nodejs module. i'm getting error back: timers.js:265 callback.apply(this, args); ^ typeerror: cannot read property 'apply' of undefined @ wrapper [as _ontimeout] (timers.js:265:13) @ timer.listontimeout (timers.js:110:15) i'm guessing i'm doing stupid, usual, there reason loses closure scope or when second interval runs? var queuesvc = function(settings){ var queue = ['bob', 'is', 'name', 'my', 'hi']; var svc = {}; var runtime; svc.addquery = function(queueentry){ queue.push(queueentry); }; svc.stopqueue = function(){ clearinterval(runtime); }; svc.startqueue = function(){ runtime = setinterval(runqueue(queue), settings.queueinterval); }; svc.emptyqueue = function(){ //this method of emptying array needs change //if decide make queue public property ...

ios - Updating Random Integers (swift, spritekit) -

i have random integer needs update every second, issue random int cannot defined outside of function because random int range of 0 screen size var randomx = uint32(self.size.width) i cannot use self.size.width outside of function. @ first thought maybe not updating because 1. declared in function didmovetoview() , 2. declared using "let" instead of "var". if declare in function updates every second, variable cannot used outside of function huge problem. you can declare var instance variable of class (outside method), update in method, , use anywhere else in instance of class. class rtest { var randomx: uint32 init() { self.randomx = 2; } func rx5()->uint32 { return self.randomx * 5 } }

css - Make div to stay in the container -

i want put button on image, if image have < height id="addgravity" top:-300px, button go out container. <div class="item"> <img src=""/><hr style="position: relative;top:-20px;"/> <div id="addgravity" style="position:relative;top:-300px;background:white; height:56px;color:white;opacity:0.9;"class="item">button</div> </div> you're making difficult using negative margins position things. why not position 'button' absolutely stays aligned in middle regardless of image size? .item { display:inline-block; position:relative; } #addgravity { position:absolute; top:0; right:0; bottom:0; left:0; background:white; height:56px; color:black; opacity:0.9; margin:auto; } <div class="item"> <img src="http://www.placehold.it/300" /> <div id="addgravity...

memory - How to dispose of multimaterial objects? -

i use multimaterial objects in scene, , wondering best way remove , dispose of them? i've read questions on how dispose of regular objects, , can use .dispose() on object, there no method multimaterial objects or regular objects(it's not listed in object3d document page). is enough dispose geometry , materials? do after that, set object null? free memory? (this concern since use lot of objects , want make sure memory released). . edit: after experimenting, appears if way dispose objects follows sequence: scene.remove(mesh); mesh.geometry.dispose(); if want remove geometry (looping through children of multimaterial object , disposing of geometry seems okay) mesh.geometry = undefined; mesh = undefined; if want remove materials used in multimaterial object, can remove each 1 material.dispose(); so if initialize material var material = new three.meshbasicmaterial(); material.dispose(); remove it. then material = undefined; textures disposed similarly. i...

Python asyncio: return vs set_result -

hello asyncio experts, how correctly return results coroutine? need use return or future.set_result? for example: @coroutine def do_something() result = yield some_function() return result or @coroutine def do_something() future = asyncio.future() result = yield some_function() future.set_result(result) you should use return result . second example end returning none , rather result . here's complete example demonstrating that: from asyncio import coroutine import asyncio @asyncio.coroutine def some_function(): yield asyncio.sleep(.5) return 5 @coroutine def do_something(): result = yield some_function() return result @coroutine def do_something_else(): future = asyncio.future() result = yield some_function() future.set_result(result) @coroutine def main(): print((yield do_something())) print((yield do_something_else())) loop = asyncio.get_event_loop() loop.run_until_complete(main()) output: ...
