i writing web application dynamically inspect collections (publications) of ddp server. 1 of issues i'm running once meteor collection created sticks around lifetime of app: foo = new meteor.collection("foo"); however, depending on user application, might no longer interested in foo. wasteful have collection linger around, potentially end entire database being stored on client. the issue made worse fact client doesn't know collections going subscribe for. think causes issues how template helpers setup. examples i've seen far show helpers returning results of particular collection, like: return foo.find(); i still getting head around how reactive model works, i'm guessing if reassign foo: foo = new meteor.collection("bar"); ... above helper code not magically update return contents of 'bar'. update: since suggestions revolve around using combination of subscriptions , single collection i'd thought give context why as...

i had neat idea (well, that's debatable, let's had idea) making implicit dependency injection easier in scala. problem have if call methods require implicit dependency, must decorate calling method same dependency, way through until concrete dependency in scope. goal able encode trait requiring group of implicits @ time it's mixed in concrete class, go calling methods require implicits, defer definition implementor. the obvious way kind of selftype la psuedo-scala: object thingdoer { def getsomething(implicit foo: foo): int = ??? } trait mytrait { self: requires[foo , bar , bubba] => //this fails compile unless dothing takes implicit foo def dothing = thingdoer.getsomething } after few valiant attempts implement trait and[a,b] in order nice syntax, thought smarter start shapeless , see if anywhere that. landed on this: import shapeless._, ops.hlist._ trait requires[l <: hlist] { def required: l implicit def provide[t]:t = required.select[t...

i'm working on c++ project , wonder if it's possible store same object in 2 different vector. know how deal in c pointer, reference same object both table, i'm little bit confused in c++. if create object , store in vector , in vector b. c++ copy object or it's same on both vector , if modify one, other modified ? in second case, take more place store twice (for accessibility issues) or it's not way deal ? thanks. cppreference great place check type of questions. let me quote relevant parts of link: void push_back( const t& value ); void push_back( t&& value ); appends given element value end of container. 1) new element initialized copy of value. 2) value moved new element. so yes, storing same element twice in 2 vectors cause copied twice. should use std::vector<t*> if don't want waste memory. , always, should consider smart pointers ( std::shared_ptr / std::weak_ptr ) instead of naked point...
