i know there lot of questions of type, did't find solution case; need current , correct nsdate object, not nsstring ! code returns wrong time (+3 hours), because i'm ukraine. nsdate *currentdate = [nsdate date]; how current nsdate object nsdateformatter ? know how nsstring , don't need it. edit: i'm using code compare 2 nsdates using nscalendar object, here code: nscalendar *calendar = [nscalendar currentcalendar]; nsuinteger unitflags = nsdaycalendarunit | nshourcalendarunit | nsminutecalendarunit | nssecondcalendarunit; nsdatecomponents *components = [calendar components:unitflags fromdate:nowdate todate:enddate options:0]; and components.hour shows me +3 hours difference nsdates stored in utc, dates itselfs dont know timezones or weeks, month, years. point in time. to see correct time position on earth surface, need take nscalendar, represents time model in account. use directly , mess around dates, or create nsdateformatter leave date

in module mongoskin when getting database object mongoskin in sync fashion, hence code: var db = mongoskin.db(url, { native_parser: true }); var mycollection = db.collection('mycollection'); i curious, how achieve this? i've been looking @ mongoskin code not understand it. and here, can see mongoskin simplifys : https://github.com/kissjs/node-mongoskin#dbcollection-callback origin vs. mongoskin anyone know how mongoskin turned async code sync fashion? they in beginning of readme : we make common use functions in promise mode, call skinclass of normal class. , api same official api. db.collection('mycollection'); returns skincollection - wrapper native collection , use collection when available. the magic lives here: https://github.com/kissjs/node-mongoskin/blob/master/lib/utils.js

does there exist thirdparty middleware or way create such middleware express.js allows intercepting requests , inspecting request's body content without affecting subsequent middleware such bodyparser or route endpoints may rely on raw body such express-http-proxy ? from can tell bodyparser seems work in obtrusive way not allow route override default parsing behavior. express documentation describes how request.body filled in middleware such bodyparser. behavior of bodyparser makes sense simplicity , performance perspective doesn't make great candidate creating middleware needs inspect contents of request , let remaining portion of app working without modification. true seeing depending on parsing middleware results may in entirely different formats. after digging i'm left wondering if it's possible pull off express or perhaps once read request body eliminate ability make use of further middleware such bodyparser or express-http-proxy expect access body directly

for example have base class , need property calculated in derived classes.i have 2 variant ( someproperty1 , someproperty2 ): public class baseclass { public int someproperty1{get;set;} public override int someproperty2{get;set;} } public class derivedclass : baseclass { public derivedclass() { someproperty1 = 100; } public override int someproperty2 { { return 100; } } } the questions best way, someproperty1 or someproperty2 ? add base class protected abstract method called calcsomeproperty() . then implement property in terms of calcsomeproperty() . force derived classes implement it. for example: public abstract class baseclass { public int someproperty { { return calcsomeproperty(); } } protected abstract int calcsomeproperty(); } alternatively, can make property abstract: public abstract class baseclass { public abstract

this question has answer here: sqs duplicate messages handeling 1 answer i not experienced used in amazon sqs service. have read messages queue not own , process them making small database of information. up until had code read messages in queue , process them. script running periodically. however, observed amount of messages in queue has become large. when took 10000 sample messages observed around 6000 duplicates. i puzzled sudden change in behavior (up until did not observe duplicate messages). queue never seems run out. this code use read messages queue. conn = boto.sqs.connect_to_region( 'myregions', aws_access_key_id='myacceskey', aws_secret_access_key='secretacceskey') q = boto.sqs.queue.queue(connection=conn, url='outputqueue') rs = q.get_messages(10) all_messages = [] while len(rs) > 0: all_messag

how calculate time taken load view/window? can done this: nsdate *starttime=[nsdate date]; //some code load window wincontroller nsdate *endtime=[nsdate date]; nstimeinterval diff = [endtime timeintervalsincedate:starttime]; nslog(@"time load %f seconds.\n\n\n",diff); but not calculate total , exact time taken. load window, , in init , awakefromnib asynchronously calls services, loads custom views, populates tableviews etc, , spread on dozens of classes/controllers , scores of methods. if use above(program shown), endtime reached while spinner continues spin , service calls in progress. i can check watching clock takes more minute load window, , ready perform action on it, diff calculates 0.5 seconds something. now problem can not change whole code of project, can insert few things in between. how this, suggestions appreciated. i know late , not sure if still searching answer or no(but might other people searching solution similar problems).but
