we moving database 1 server another. there many connection strings of applications needs changed due this. there generic way can keep connection string if move database again issue doesn't arise?? there many ways resolve problem. ultimately sounds want centralize database connection strings in such way database migration (mostly) transparent application. can think of few options here: use "control database" houses connection strings , configurations. if migrate new database server, have update single connection string in application, , perform data updates else. use. use central xml configuration file parsed on application startup. use sql server aliases and/or add additional ips machine can migrate between servers. way when move new database server can still bring along existing aliases/ips server (unless need run in parallel of course) , theoretically not need update in code, provided you've referenced appropriate aliases. see here more info

__block nshttpurlresponse *httpresponse; dispatch_semaphore_t semaphore = dispatch_semaphore_create(0); nsurlsessiondatatask *task = [session datataskwithrequest:request completionhandler:^(nsdata *data, nsurlresponse *response, nserror *error) { if (!error) httpresponse = (nshttpurlresponse *)response; } dispatch_semaphore_signal(semaphore); }]; [task resume]; dispatch_semaphore_wait(semaphore, dispatch_time_forever); is safe read httpresponse after this? semaphore waits block compete execution. if there no error, assignment seen or have synchronise or create memory barrier outside block? does waiting on semaphore implicitly perform synchronisation makes __block variable safe read immediately. if done thread.join() in java instead of semaphore, safe since guarantees happens-before relationship assignment in "block". the short answer yes. the semaphore lock forces thread operating stop execution until receives enough unlock signals

Adding compression to existing mongodb collection -

is possible add compression existing collection created prior mongodb 3.x? if so, how? i found example of how create new collection compression, haven't found far strategies adding compression existing one. http://www.mongodb.com/blog/post/new-compression-options-mongodb-30 version prior 3.x mongodb had 1 storage engine - mmapv1 still not support compression. 3.0 mongodb introduced pluggable storage engines, , 1 of them - wiredtiger storage engine supports compression. the problem cannot use data files created 1 storage engine (say mmapv1 ) 1 (e.g. wiredtiger ). so thing can mongodump , initialise mongod --storageengine wiredtiger using data directory (with --dbpath ), , mongorestore new mongod instance.
