i have subdomain, http://m.abc.com . on google analytic account, defined property subdomain. tracking code copied , pasted on subdomain files. on google analytics reporting, need demographics info. i've added code generate report: but when click validate code, validation not proceed. page below: i've gone on instructions , did not miss out item. i've turn on enable advertiser features , enable demographics , interest reports. is there else need do? it typically takes @ least 48 hours displayfeatures validate (at least took long me). if after 48 (or 72) hours it's still not validating, can skip step without detriment.

i'm using opentk warpper c#, shaders weren't running correctly (i want generate vertex displacement shader using textures), pretend use gpu debugger see happening. the application quite simple. creates game window, load shaders, textures , render textured cubes (so it's working fine, discovered problem trying use vertex displacement). i used gdebugger , amd codexl same results. debugger detects shaders, vbos, etc never see allocated textures. have non-sense because when i'm running application see textured cube spinning around screen , debugger render object on back/front buffer. for reference, here texture-loading function: int loadimage(bitmap image,int tex) { int texid = gl.gentexture(); gl.bindtexture(texturetarget.texture2d, texid); system.drawing.imaging.bitmapdata data = image.lockbits(new system.drawing.rectangle(0, 0, image.width, image.height), s

nsuserdefaults.standarduserdefaults().dictionaryrepresentation().keys returns [nsobject] need (and expect) [string] . coffee i'm missing? that returns lazybidirectionalcollection<mapcollectionview<dictionary<key, value>, key>> . can add .array array instance back, use map cast values string : let keys = nsuserdefaults.standarduserdefaults().dictionaryrepresentation().keys.array.map { $0 string } println(keys) // [nslanguages, nsinterfacestyle, applelanguages]

we using rails engine has able access models , behavior containing application, because we're testing in dummy application can't test things , end mocking , stubbing entire left half of world out write simple tests. is there way, via configuration, code or ritual sacrifice of farm animal, can have our engine tests run in context of containing application rather in dummy test application? i approach differently establish interface consuming application should observe. assume valid application use gem on way it's supposed to given defined interface, application using gem should same gem standpoint. having mock application sets example domain tested in context of gem becomes ok. don't mock anything, create application actual models or layer required interact engine if there's no way define how used, or still want enable consumers test integration points, provide test helpers. rack-rest , provides test infrastructure rack users. those can require

i have several features below test outcome of data processing. feature: a scenario: a1 given load data a2 output a1 output_a1 scenario a2 given load data a2 output a2 output_a2 i data loading first , check output later below because faster. given load data a2 given load data a2 output a1 output_a1 output a2 output_a2 is there way behind scenes , present reports in first case? i thinking of way tell cucumber run given scenarios first , scenarios later. cucumber doesn't distinguish between given , keywords can't tell cucumber run givens first. you set scenario run before others: scenario: load data given data exists load data in load of data following scenarios scenario: a1 given a1 data loaded output a1 output_a1 where given step checks data loading

i using spring mvc controller , want start execution of task new thread. thread should not start after response has been sent client. means - in strict temporal order: request return new responseentity ... / client receives http status 200 ok. processing of task begins. how achieve ? i wanted use spring's async abstraction, calling method annotated @async, way have not guarantee new thread waits response sent. you can use interceptor that. order or events handling request in spring mvc : dispatcherservlet request, response pair , determines handling [optional] interceptors prehandle called (with option stop processing) controller called [optional] interceptors posthandle called viewresolver , view actual response processing , send response [optional] interceptors aftercompletion called the above on simplificated , aimed @ showing interceptor aftercompletion methods called after response has been sended client, following signature : void afterco

i know elasticsearch uses relevance ranking algorithms such lucene's tf/idf, length normalization , couple of more algorithms rank term queries applied on textual fields (i.e. searching words "medical" , "journal" in "title" , "body" fields). my question how elasticsearch rank , retrieve results of filter or range query (i.e. age=25, or weight>60)? i know these types of queries filtering documents based on condition(s). lets have 200 documents age field value 25. of documents retrieved top 10 results? does elasticsearch retrieve them order indexed them? from elasticsearch documentation: filters : general rule, filters should used instead of queries: for binary yes/no searches for queries on exact values queries : general rule, queries should used instead of filters: for full text search where result depends on relevance score so when running search such "age=25, or weight>60" should using f

i'm trying add nservicebus in web api hosted in owin. goal able make simple bus.send() inside controller. found plenty of blog posts, stackoverflow answers, etc. still no luck in accomplishing simple task. i'm working on project based on these 2 posts (i did not start suspect ex collegue have taken somewhere on web) : injecting nservicebus asp.net mvc 3 , web api adaptation : injecting nservicebus asp.net webapi i have resolver adapter : public class nservicebusresolveradapter : idependencyresolver { private ibuilder builder; public nservicebusresolveradapter(ibuilder builder) { this.builder = builder; } public object getservice(type servicetype) { if (typeof(ihttpcontroller).isassignablefrom(servicetype)) { return builder.build(servicetype); } return null; } public ienumerable<object> getservices(type servicetype) { if (typeof(ihttpcontroller).isassignablef

two different ways create data.frame lead different result: a <- c(1,2) b <- c(3,4) df1 <- as.data.frame(cbind(a, b)) df1 str(df1) mean(df1$a) this works fine but: a <- list(1,2) b <- list(3,4) df2 <- as.data.frame(cbind(a, b)) df2 str(df2) mean(df2$a) leads warning: [1] na warning message: in mean.default(df2$a) : argument not numeric or logical: returning na i encounter problem when parsing json file data.frame , found made mistake assuming column of data.frame vector , list instead. when it's list , not mean , many other functions summary and as.date won't work expected. data type data.frame no longer "safe" me, passing data.frame input without knowing how created means need convert columns vector explicitly, , there might more complicated issue list , vector coexist: df3 <- df2 df3$a <- as.numeric(df3$a) str(df3) so tried convert columns vector : data.frame(lapply(df3, function(x) {if (is.list(x)) do.call(c, x
