i using okhttp send http request android apk. due server-side proxy requirement, url endpoint like: " https://api.example.com ", in http request, overwrite host header "host: proxy.example.com". tried use like: httpurl url = new httpurl.builder() .scheme("https") .host("api.example.com") .build(); okhttprequest = new com.squareup.okhttp.request.builder() .url(url) .method("get", requestbody) .header("host", "proxy.example.com") .build(); response = mokhttpclient.newcall(okhttprequest).execute(); however, when looked http request in network packages, host header still "api.example.com". wonder, advice can overwrite host header? lot! by default okhttp won’t let set host header that’s different url’s host. can hack using network interceptor sets host header.

nsmutablearray not thread-safe, don't see why can't designed thread-safe long different indices being manipulated simultaneously. e.g. index 1 points instance of class x , index 2 instance. isn't efficient allow these 2 objects manipulated @ same time? allowed when use gcd or need use dispatch barrier when changing objects pointed different indices? think of this. your array contains pointers objects. pointers signposts, pointing objects located in memory. now when mutate object, don't touch pointers object. object's location in memory unaffected. therefore, array's point of view, nothing happens when mutate objects in it, pointers remain unaffected. this means mutating different objects in array different threads safe. therefore, correct when it's more efficient download data in parallel different objects in array. so long you're not mutating array itself (adding or removing objects) or mutating same object concurrently, you...

sorry such simple question. i've been using tutorialspoint.com learn c++. i'm trying learn classes , operator overloading. other member function, website uses convention class box { private: int volume; public: box(int num); ... } box::box(int num) { volume = num; } however, when overloading operators, use this class box { private: int volume; public: box(int num); box operator+(const box &b) { box box; box.volume = this->volume + b.volume; return box; } } they define overloading function inside class. possible define outside class? if so, how? i've tried box box::operator+(const box &b) {...} box::box operator+(const box &b) {...} but these don't work how do outside of class? again, sorry such simple question. thanks edit code looks this #include <iostream> #include <string> using n...

i want setup compound index on fb_id , ts in mongodb. so, did: primary> db.sessions.ensureindex( { fb_id: 1, ts: 1 }, { unique:true } ); but got following error: e11000 duplicate key error index: tracking.sessions.$fb_id_1_ts_1 dup key: { : null, : null } so checked indexes in collection using db.sessions.getindexes() , got: [ { "v" : 1, "key" : { "_id" : 1 }, "ns" : "tracking.sessions", "name" : "_id_" } ] it doesn't duplicate key me. doing wrong here? mongodb tells you have several documents (more one) same fb_id , ts values, null values. in other words, there documents without fb_id , ts fields. so, violates unique constraint across collection. as workaround, should take @ sparse indexes. quote docs: sparse indexes contain entries documents have indexed field. document missing field not indexed. index “spa...
