when using linq extension methods enumerable.select, better use lambda expression, or regular method? i'm asking both respect (memory) optimization*, , readability**. example code: private void main() { var array = new int[1]; var result1 = array.select(x => x.tostring()); // lambda var result2 = array.select(linqhelper); // method } private string linqhelper(int x) { return x.tostring(); } * i'm thinking of closures creating scopes unused instantiated variables in them, because variables in scope when lambda created . edit - stupid thinking, since variables captured closure when they're referenced in lambda expression. **both options ok me. from optimization point of view, there should no difference. from readability point of view, i'd think whether need same logic in several places. if so, use method , use method group conversion. way don't repeat yourself, don't have change several bits of code if requirements c...

i'm working on old client application running under rails 2.3.11 on windows server 2003. application relies on simple catch-all route (hell yeah!) : map.connect ':controller/:action/:id' i have nested modules , working fine on windows (prod) , mac os (dev). url_for(:controller=>'/settings/users', :action=>:index) #=> settings::users#index recently changed mac os ubuntu 11.04. works, except these nested routes. url_for(:controller=>'/settings/users', :action=>:index) #=> settings#users does have clue going on? why problem linux only? it's not os-specific problem if affects routing in such specific way. there reason you're prefixing controller name / ? named routes avoid of mess being specific, it's unfortunate you're left without them. there's slight difference in gem versions on 2 systems, maybe subtle.

i'm building centralised django application interacting dynamic number of databases identical schema. these dbs used couple legacy applications, of in php. our solution avoid multiple silos of db credentials store info in generic setting files outside of respective applications. setting files created, altered or deleted without django application being restarted. for every request django application, there http header or url parameter can used deduce setting file @ determine database credentials use. my first thought use custom django middleware parse settings files (possibly caching) , create new connection object on each request, patching django.db before orm activity. is there more graceful method handle situation? there thread safety issues should consider middleware approach? rereading file heavy penalty pay when it's unlikely file has changed. my usual approach use inotify watch configuration file changes, rather trying read file on every request....

suppose have simple c++ program takes in inputs , outputs string.
