suppose that i have function a f() ; i want initialize local variable a return value of f ; i don't want rely on rvo; what best option (and why) avoid return value of f being copied when a may have modified i know a not modified options: a) a = f(); b) a&& = f(); c) const a& = f(); d) const a&& = f(); edit: i say: b) c) because both use references , avoid copy (which avoided rvo well, not guaranteed). how come see option a) suggested of time? i guess heart of question is: a) has same effect c), why not use c) instead of a), make things explicit , independent on compiler? so how come see option a) suggested of time? because 4 options return value exact same way. thing changes way bind variable returned temporary. a) declares variable a of type a , move-initializes temporary. not assignment, initialization. move constructor elided popular compiler, provided don't explicitly disallow it, means pr...

i have mongodb collection. each document in collection has x,y coordinations representing position on grid. given point (x',y') retrieve top k documents position closest (x',y') euclidean distance. i'm using mongodb rails app. calculation on db if it's possible. how can it? if store coordinates array [x, y], need create geospatial index ("2d") on field. to query index: db.runcommand({geonear: <collection>, near: [x, y], limit: k}) if on mongodb 2.4, preferred way use geojson format (i.e. {type: "point", coordinates: [x, y]}) , "2dsphere" index, legacy format supported. to query index: db.runcommand({geonear: <collection>, near: {type: "point", coordinates:[x, y]}, limit: k}) the geonear command returns results ordered distance. here documentation: 2d index - http://docs.mongodb.org/manual/core/2d/ 2dsphere index (2.4) - http://docs.mongodb.org/manual/core/2dsphere/
