is there difference between context.request.cookies , context.requestcookies ? both properties seem have identical values. confusing. it's same. following implementation of requestcookies property of microsoft.aspnet.signalr.hubs.hubcallercontext class: public idictionary<string, cookie> requestcookies { { return this.request.cookies; } } you can validate decompiling microsoft.aspnet.signalr.core.dll. actually, since open-source, don't need decompile, code can downloaded github: https://github.com/signalr/signalr/blob/master/src/microsoft.aspnet.signalr.core/hubs/hubcallercontext.cs

i want concatenate 2 characters '7' , '9' form string "79". first, initialized variables. (restriction: have use char types , must not make charac alike variable.) char *charac = (char *) malloc(sizeof(char) * 200); char *combined = (char *) malloc(sizeof(char) * 200); then gave values charac[0] , charac[1]. charac[0] = '7'; charac[1] = '9'; printf("charac[0] : %c\n", charac[0] ); printf("charac[1] : %c\n", charac[1] ); i want concatenate charac[0] , charac[1] strcpy(combined, (char*)charac[0]); strcat(combined, (char*)charac[1]); printf("combined : %s\n", combined); free(combined); but code above doesn't work. got error message: "warning: cast pointer integer of different size". after reading of comments , suggestions, obtain output result want. here final code: char *charac = (char *) malloc(sizeof(char) * 200); char *combined = (char *) malloc(sizeof(char) * 200); ...

my app using parse library push notifications, requires permissions work properly. i've noticed of potential users of application bit suspicious in particular of permission get_accounts: think access personal data or :-/ i looked @ android documentation (see here ) , seems get_accounts required push notifications devices running os versions below 4.0.4, rid of permission @ least higher os versions. what best way achieve this?. imagine use play store multiple apk support, necessary removing single line of permissions in manifest file?. hope there better solution far couldn't find out other. use android:maxsdkversion on <uses-permission> manifest entry: <uses-permission android:name="android.permission.get_accounts" android:maxsdkversion="13" /> note: should still test on both android versions parse may still check account on higher versions of android.

i new image processing , opencv in particular. i working on ocr project in need identify numbers. this image process: lets optimized image, questions are: in image number apeared several times, lets found contours, how can know 1 if the best 1 process? how can know in angle need rotate each contour make stright? in image number apeared several times, lets found contours, how can know 1 if the best 1 process? you want biggest number, because least warped perspective. want numbers in middle of image, because n middle of ball. how can know in angle need rotate each contour make stright? have @ rotated rect . explained how find angle in thread . since have centered ball, should think using mapping "unwarp" ball (so projection globe onto map). should pretty straightforward afterwards find numbers on flat image. edit: since have 10 numbers might "brute force" solution big enough training set. throw numbers detect classifier , ...

i took on development of relatively mature wpf mvvm project didn't have lot of unit tests. once understood of code doing thought it'd idea write more. now, don't have experience of either mvvm or wpf seems obvious given relatively limited, property-based binding between ui , code, lot of logic can locked away behind private methods. that's i'd have done, , that's predecessor had done. unit testing private methods bit of pain (i know how use privateobject, it's clumsy), , reading around discussion on subject there seemed fair number of people evangelising decreased use of private methods facilitate testing. so got me thinking: primary reason locking things behind private methods other developers using object don't overwhelmed near-useless methods, right? in wpf mvvm you're invoking objects xaml, there's limited intellisense , need know names of you're calling before so. so ... there reason using private methods when coding in parad...

long time reader first time poster here on :) for last couple of days i've been setting factorygirl. yesterday changed factories (mainly user , brand factories) replacing: language.find_or_create_by_code('en') with: language.find_by_code('en') || create(:language) because first option creates language object code attribute filled in; while second uses language factory create object (and fills in attributes specified in factory) now when run test fails on factory.lint, stating user (and admin_user) factories invalid. reverting above code doesn't fix , stack trace provided factorygirl.lint pretty useless.. when comment lint function, tests run fine without issues. when manually create factory in rails console , use .valid? on it, returns true i'm @ loss why lint considers factories invalid. my user factory looks this: factorygirl.define factory :user ignore lang { language.find_by_code('en') || create(:langu...
