how can allocate shared memory accessible multiple processes using native c++ operations? or should use os api in case of inter thread synchronization objects such mutex , semaphores are? (i mean can not use bool instead of mutex. os has specific types organizing synchronization.) there no notion of "shared memory", or "process", in "only native c++". platform-specific concepts. you can try boost's interprocess library useful abstractions.

i have application written in vb.net reads data sql server 2008 r2. @ time of login, user select 1 of many database files (available in dropdown list) , keys in username , password login. while logging in, application reads table in selected database called 'strings' , while loop put values in 25-30 variables creating working environment of application. i have put in time tracking @ beginning , end of while loop , shows 1 of database, takes 26 seconds read values , takes 0 seconds (since not tracking @ mili-seconds level). ironically, 'strings' table in database takes 26 seconds has 125 rows , database takes 0 seconds has 159 rows. apparently, code same, , database structure true replica (both databases generated using same script). i have thought of possibilities not sure why there's such huge difference delays login time of user. can please put light on how can figure out? thanks without specific information rather difficult find going on. r...

i wondering why in todomvc backbone marionette , marionette.layout used footer instead of simple itemview header ? also why use compositeview todolist.views.listview instead of collectionview ? i don't see need using layout in footer. think author thought maybe need add regions footer , used layout , in actual implementation? no need. about compositeview instead of collectionview . collectionview doesn't allow have template on it. imagine need show list of clients don't want simple <ul> show clients, want headers, information , <ul> compositeview can add template can contain header, information , of course <ul> . in concrete case, wants show checkbox list, since needs show markup apart <ul> needs compositeview able add template. tl;dr use collectionview if don't need markup , if so, use compositeview

the gettext-tutorial states the preferable way create i18n object through i18nfactory. factory caches i18n object internally using the package name of provided class object , registers i18nmanager. classes of same package use same i18n instance. but running inside httpservlet (actually velocityviewservlet in particular case) seems me if change locale on cached object stay subsequent requests , not desirable because each request must served particular locales. so question is, should instead create ad-hoc i18n objects on per-request basis, specific locale of request? think performance penalty, should instead create own manager , select appropriate instance based on request's locale? any comments appreciated. there doesn't seem doc or examples besides tutorial , javadoc. update: there 1 thing tried , seems work. instead of declaring private static member tutorial says, call factory method on each request, using special version of i18nfactory: geti18n(java.lang...

we produce toolkit can supported various ioc containers, toolkit ioc-agnostic , provide basic support different containers. working support autofac, need allow end users override our configuration, part, based on conventions. i'll explain happens windsor understand if there similar mechanism autofac. the toolkit provides set of built-in services/component "automagically" registrated in end-user container. windsor register "fallback" if user register same service "default" user component resolved overriding our registration. the interesting thing of approach works regardless of order in components registered. any way achieve same behavior autofac? .m i think you're looking preserveexistingdefaults extension. can read more in autofac wiki: https://code.google.com/p/autofac/wiki/componentcreation
