so have program supposed match babysitters people based on inputted info. info both parties saved in linked lists. is possible match data babysitter linked-list parent linked-list? , make output "__ possible matched you" if not have data, simple inefficient way of solving problem is: boolean matches(person person, babysitter babysitter) { // implement logic returns whether babysitter , person match return person.getnumberofchildren() <= babysitter.getmaximumnumberofchildren() && babysitter.getworkingdays().containsall(person.needsbabysitterfordays()); } (person person: people) { (babysitter babysitter: babysitters) { if (matches(person, babysitter)) { system.out.println("babysitter " + babysitter + " recommended " + person); } } } the above algorithm takes o(b * p) time b = number of babysitters, p = number of people. large b , p, slow. based on logic of matches achieve sol...

i have code parses metadata of qt plugin wrote exposes functionality via interface. plugin's main class inherits qobject, when reading metadata, methods declared , publicly available in qobject, among them: destroyed(object *); objectnamechanged(qstring); etc... i want parse methods introduced in plugin's main class, , not methods have been inherited qobject, looking @ properties qmetamethod provides, don't see way. have access methods qmetaobject include qobject's methods well. one way solve parse metadata of qobject exclude it's methods plugin's main class. last resort. wondering if qt provides out of box. you can use qmetaobject::methodoffset() method index current class' methods start, , iterate there rather starting @ index 0: const qmetaobject *object = metaobject(); // gets methods on actual class. (int = object->methodoffset(); < object->methodcount(); ++i) { qdebug() << object->method(i).methodsignature()...

i have infinite stream messages represented plays enumerator apply iteratee . each message processed akka actor (number of actors limited 10). now code in iteratee asynchronously wait free actor if 10 actors busy , not send them messages leads exception ask timed out on ... . how can achieve such functionality? there better way process infinite stream 10 actors without await ? example of code talking this: val workers = context.actorof(props[myworker].withrouter(roundrobinrouter(10))) val = iteratee.foreach[msg] { msg => workers ? msg } msgenumerator.apply(it) use iteratee.foldm actor ask pattern have here seems right approach. assuming don't want actors build large mailboxes (if don't care large mailboxes, use tell , iteratee.foreach instead of ask ) require specialized routing logic. since api making custom akka router doesn't support asynchrony, need custom actor handle logic of distributing 1 piece of work each actor in actor pool @ time...

do know if there's kind of tool less css javascript allows import example "plugin-1.js"; in .js file. i'm working sublime text 2 build less (which references dotless.exe), maybe if you've tried it'll awesome if can share us. if you're in html javascript in web can organize imports libraries require.js or include script tag above 1 you're using in html. <script src="plugin-1.js" type='text/javascript'> </script> otherwise, if you're using node.js done require() directive such var othermoduletorequire = require("plugin-1.js"); after available in file. it worth mentioning while similar @import in functionality behave differently doing importing in run time instead of bundling files 1 @import does. if care bundling files (for example in production under load) can use minifiers , optimizers the closure compiler or the require.js optimizer if chose use require.js.
