i have strange bug occurring. i'm monitoring sound levels using avaudiorecorder , calling action when sound peaks on level. works on simulator using ios 6 , on device connected xcode using ios 7. when distribute app via testflight audio peak method never triggers. when distribute via ad-hoc , install via itunes have same problem. why work on device connected xcode not through ad-hoc build? edit: i've did more testing , problem related microphone. metering enabled app isn't getting levels it. metering working when i'm debugging not ad-hoc. why work on device connected xcode not through ad-hoc build? sounds you've failed include microphone among "required device capabilities" in info.plist: microphone include key if app uses built-in microphone or supports accessories provide microphone.

how reference element doesn't exist yet within javascript object instance? var dynamic = function(el) { this.$instance = $(el); } var dynamicinstance = new dynamic('#dynamic'); since #dynamic element loaded via ajax, script doesn't see when dynamicinstance created , can't reference it. if helps solve issue, reference element inside object without passing in when it's created -- still unclear on how make object aware of element. if want keep things decoupled can accept callback function parameter , call once new element loaded , appended dom function doajaxcall(callback) { $.ajax({ success : function(response) { //logic create new element based on response callback(); } }); } doajaxcall(function() { var dynamic = new dynamic('#dynamic'); }); in way keep decoupled while avoiding race condition created ajax calls.

i using product advertising api amazon. little lacking honest, since there no way of getting product name. can title, contains offer "amazon kindle 3g, free wifi..." instead of amazon kindle 3g. more importantly, there seems no way of getting stock information. need know if item in stock or not. that's all, there seems no way of doing yet. ama missing something. using itemlookup api. details using large response group no stock information the various 'offers' response groups list 'offers' amazon , 3rd party merchants; data includes availability details pricing (just) 1 offer tell about. can supply merchantid parameter forcing 1 offer amazon. this api has been limited (i.e. 1 offer) since 2011; fuller info try mws api instead. for more literal product name, try obtaining upc or ean itemattributes response group, , looking in non-amazon upc database. no idea how work in practice.

i have make table out of 2 other tables (and use union). query works is: select * tabel1 union select * tabel2 now have put result(data) table3 (a table have, same columns in table1 , table2). who can me? insert table3 select * tabel1 union select * tabel2 since have same columns in 3 of them ... in general case should work column lists like insert table3 (col1, col2, col3) select col1, col2, col3 tabel1 union select col1, col2, col3 tabel2 this way avoid trouble auto_increment id-columns. should consider using union all since union filters out duplicate lines , therefore take longer on large tables.

so i'm having problem finding number of rows in excel document has data in it. here's have far: (int = 2; <= b; i++) { if (!(worksheet.get_range("a" + i, misvalue).formula == null)) { a.add(worksheet.get_range("a" + i, misvalue).formula); } } at moment i'm crudely shuffling through large number of lines, questioning whether it's null or not, adding contents list. there has easier way google has yet show me. in advanced i might not understanding question properly, i'm guessing you're trying find cells in column have value in them , i'm assuming you're using excel interop in c#... for that, can use range.specialcells method. so, example, cells constant values or formulas use: worksheet.range("a:a").specialcells( microsoft.office.interop.excel.xlcelltype.xlcelltypeconstants | microsoft.office.interop.excel.xlcelltype....

(the transport can re-use connection if body has been read, because if reused connection unread body next request made using connection receive previous request's response!) so reading body more efficient close()ing if you're making more 1 request - tls connections relative...

i need insert around 2500 rows using ef code first. my original code looked this: foreach(var item in listofitemstobeadded) { //biz logic context.mystuff.add(i); } this took long time. around 2.2 seconds each dbset.add() call, equates around 90 minutes. i refactored code this: var tempitemlist = new list<mystuff>(); foreach(var item in listofitemstobeadded) { //biz logic tempitemlist.add(item) } context.mystuff.tolist().addrange(tempitemlist); this takes around 4 seconds run. however, .tolist() queries items in table, extremely necessary , dangerous or more time consuming in long run. 1 workaround context.mystuff.where(x=>x.id = *empty guid*).addrange(tempitemlist) because know there never returned. but i'm curious if else knows of efficient way to bulk insert using ef code first? validation expensive portion of ef, had great performance improvements disabling with: context.configuration.autodetectchangesenabled = false; cont...

i know email forms can attract spam, can captcha attract spam? i have wordpress website 19 contact forms (one each company advisor). test, put captcha on 1 of contact forms see if form received less spam other forms. 2 months goes by, no spam @ of 19 forms. today though, 10 spam messages sent through 1 of forms. odd was form had captcha spam sent though, other 18 forms untouched (and easy find). any idea why or how have happened, , can prevent happening again? *edit page captcha/contact form on not indexed (noindex nofollow yoast plugin). thanks! my first thought make use of called invisible captcha or honeypot technique. in nutshell, invisible captcha relies on principle bots detect hidden fields , fill in information. human visitor, on contrary, never see them (as hidden css), therefore remain empty. aware of wordpress plugin invisible captcha, works on comments , not seem useful in case. hope of help.

i reading text file python, formatted values in each column may numeric or strings. when values strings, need assign unique id of string (unique across strings under same column; same id must assigned if same string appears elsewhere under same column). what efficient way it? use defaultdict default value factory generates new ids: ids = collections.defaultdict(itertools.count().next) ids['a'] # 0 ids['b'] # 1 ids['a'] # 0 when key in defaultdict, if it's not present, defaultdict calls user-provided default value factory value , stores before returning it. collections.count() creates iterator counts 0, collections.count().next bound method produces new integer whenever call it. combined, these tools produce dict returns new integer whenever you've never looked before.

in drivers see these 3 types of init functions being used. module_init() core_initcall() early_initcall() under circumstances should use them? also, there other ways of init? they determine initialization order of built-in modules. drivers use device_initcall (or module_init ; see below) of time. initialization ( early_initcall ) used architecture-specific code initialize hardware subsystems (power management, dmas, etc.) before real driver gets initialized. technical stuff understanding below look @ init/main.c . after few architecture-specific initialization done code in arch/<arch>/boot , arch/<arch>/kernel , portable start_kernel function called. eventually, in same file, do_basic_setup called: /* * ok, machine initialized. none of devices * have been touched yet, cpu subsystem , * running, , memory , process management works. * * can start doing real work.. */ static void __init do_basic_setup(void) { cpuset_init_smp(); userm...

json parse: http://www.dota2.com/jsfeed/heropickerdata?v=18874723138974056&l=english hero class , json serialization case class hero( var id:option[int], name: string, bio: string, var truename:option[string] ){} implicit val modelreader: reads[hero] = json.reads[hero] reading data val future: future[play.api.libs.ws.response] = ws.url("http://www.dota2.com/jsfeed/heropickerdata?v=18874723138974056&l=english").get() val json = json.parse(await.result(future,5 seconds).body).as[map[string, hero]] var = 1 json.foreach(p => { p._2.truename = some(p._1) p._2.id = some(i) p._2.committodatabase += 1 }) i need id of each hero. order of heros in json matches id. map unordered , wont work. have other ideas? i have tried use linkedhashmap. tried make implicit reads linkedhashmap i've failed. if thinks answer please give me guidance? it keeps saying "no json deserializer found type scala.collection.mutab...

i trying use "api/location" stated in documentation reason that's failing error code 0 , type transient , not helpful. ideas. var loc = location.query(); loc.load(['latitude']).done(function(loc) { console.log("lat:" + loc.latitude); }).fail(function(track, error){ console.log(error); }); also, if can explain how location retrieved. according answer on question: https://stackoverflow.com/a/20196967/1036087 location api never worked , they're going remove documentation on it.

as know, page fault exception caused when process seeking access area of virtual memory not mapped physical memory, when write attempted on read-only page, when accessing pte or pde reserved bit. regards reserved bit case, know how page table built process , kernel page table? when building page table of process, how can reserved bit of pte or pde set? is set mmu or os?. thank you, cpu can understand virtual addresses regardless of whether kernel page or user page. mmu uses pte convert virtual address physical address. go through paging more info

i trying make application, fetches image storage , place application image size looks it. scaling bitmaps memory can memory intensive. avoid crashing app on old devices, recommend doing this. i use these 2 methods load bitmap , scale down. split them 2 functions. createlightweightscaledbitmapfromstream() uses options.insamplesize perform rough scaling required dimensions. then, createscaledbitmapfromstream() uses more memory intensive bitmap.createscaledbitmap() finish scaling image desired resolution. call createscaledbitmapfromstream() , should set. lightweight scaling public static bitmap createlightweightscaledbitmapfromstream(inputstream is, int minshrunkwidth, int minshrunkheight, bitmap.config config) { bufferedinputstream bis = new bufferedinputstream(is, 32 * 1024); try { bitmapfactory.options options = new bitmapfactory.options(); if (config != null) { options.inpreferredconfig = config; } final bitmapfactory.options decod...

i tried use debugger in eclipse, when hit breakpoints, eclipse "debug current instruction pointer" pointing @ wrong source line.i want remove "debug current instruction pointer". "project -> clean..." doesn't seem help, nor restarting eclipse, nor rebooting. go debug view (as current debug session running) , complete or terminate current debugging session. way rid of "debug current instruction pointer"

i have 2 for loops in code running same number of loop cycles. these 2 loops independent (each loop works on different input data). within 1 loop, there cpu functions , several kernels not running concurrently. can run these iterations on separate gpus? you can run involved kernels separately on 2 different gpus. you have take care synchronization of cpu processings on partial outcomes of 2 gpus. due presence of sequential part, perhaps not experience maximum possible speedup factor of 2 when working 2 gpus. starting cuda 4.0, can use cudasetdevice() set current context corresponding given device without need of creating streams enable multi-gpu processing.

... when call function in console returns undefined. i'm javascript newbie i'm making basic mistake, i'd greatful if me out :-). here code: var randomprint = function(){ x = math.floor(math.random() * 100); y = math.floor(math.random() * 100); z = math.floor(math.random() * 100); console.log(x, y, z); if(x > y && x > z) { console.log("the greatest number is" + " " + x); } else if(y > z && y > x) { console.log("the greatest number is" + " " + y); } else if(z > y && z > x) { console.log("the greatest number is" + " " + z); } }; randomprint(); the answer deceze better solution, see working well. example output in console is: 35 50 47 greatest number 50 undefined the undefined part because function not returning anything. write as var randomprint = function(){ x = math.floor(math.random() * 100); ...

i want ask question processing. have user defined object class, point, , have 2 data members x , y both declared float. have class recognizer. need create constructor of recognizer , inside define object of point[] point0, point[] point1 , etc... dynamically. point [] point0={new point(137,139),new point(50,63),..., new point(78,5)}; point1[],point2[],...,pointn[] how else can add values point0 having values of corresponding x , y coordinate. also note size of each object point1,point2,..., pointn different. how can achieve above goal? how using 2 dimensional array ? point [] points0={new point(137,139),new point(50,63),new point(78,5)}; point [] points1={new point(147,139),new point(60,63),new point(79,5)}; point [] points2={new point(157,139),new point(70,63),new point(80,5)}; void setup(){ point[][] pointlists = {points0,points1,points2}; recognizer r = new recognizer(pointlists); } class point{ float x,y; point(float x,float y){ this.x = x; ...

guys have been trying since hour. unable figure out why aspect.after/before not being called. code. require([ "dojo/aspect", "dojo/on", "dojo/dom", "dojo/domready!" ], function( aspect, on, registry, dom) { var callback = function() { alert("called click"); }; var callback2 = function() { alert("called click 2"); }; var = { clicking : on(dom.byid("alertbutton"), "click", callback) }; aspect.after(my, "clicking", callback2); }); thanks in advance. maybe confusing usage. aspect.after or aspect.before , execute additional functions base on methods. not action. example: aspect.after(my, "clicking", callback2); anywhere calling my.clicking() run callback2 . not execute additional function when running on(dom.byid("alertbutton"), "click", callback) . my english not good, simple explain: f...
