suppose need run few concurrent tasks. i can wrap each task in future , wait completion. alternatively can create actor each task. each actor execute task (e.g. upon receiving "start" message) , send result back. i wonder when should use former (with future s) , latter (with actor s) approach , why future approach considered better case described above. because syntactically simpler. val tasks: seq[() => t] = ??? val futures = tasks map { t => future { t() } } val results: future[seq[t]] = future.sequence(futures) the results future can wait on using await.result or can map further/use in for-comprehension or install callbacks on it. compare instantiating actors, sending messages them, coding receive blocks, receiving responses them , shutting them down -- require more boilerplate.

in app have contentprovider attached table in database cursorloader fills listview in 1 of activities. table filled empty default , gets filled user input data. want allow user delete of stored data , i'm deleting entire database when option selected. database recreated in it's default state when user starts using app again, first time used app. my issue when delete database, contentprovider doesn't detect database deleted , when go listview activity, list still there. i'm making app reload listview activity instead of resuming memory , list still there though database empty. way can contentprovider reload kill app in system settings , open again. is there way forcefully restart contentprovider or tell data has been updated outside of contentprovider class itself? you can use delete method of content provider without defining selection: context.getcontentresolver().delete(yourprovider.content_uri, null, null);

it hard come title... (i'm not native english speaker.) struct { int value; operator+(int i) const { a; a.value=value+i; return a; }; }; int main(){ a; a.value=2; a=a+2; return 0; } this code compiles/works expected, when change a=a+2 a=2+a, won't compile anymore. gcc gives me error: no match ”operator+” in ”2 + a” is there way somehow make 2+a work a+2? you need free function, defined after class struct { // ... }; operator+(int i, const a& a) { return a+i; // assuming commutativity }; also, might consider defining a& operator+=(int i); in a implement both versions of operator+ free functions. might interested in boost.operators or other helpers simplify a , see profile 2 options.

i've taken on development of new system previous developer, , honest it's mess. all diary items ahead 1 hour, format saved in 1355385600. fields responsible time start_time , end_time. i need way bulk update of entries in database , remove hour them. do guys have ideas on how can achieve this? cheers note: should have mentioned default timezone set correctly 'europe/london' , when add new diary entry times correct. need though, find way bulk update current entries in database go 1 hour. possible? you need set timezone. for sites, set timezone date_default_timezone_set('europe/berlin') , , when insert datetime in database, use date('y/m/d h:i:s') . for yours, instead of date('y/m/d h:i:s') , should strtotime(date('y/m/d h:i:s'))

suppose have send 2 consecutive kernel calls device. wait complete first 1 or executed them concurrently? if executed in parallel, intersect each other instance memory access? paradigm used such case in cuda? two consecutive kernel launches same cuda device run concurrently if : they launched same cuda context. they executed on different cuda streams. the device supports concurrency (compute 2.0 , later). there sufficient resources (registers, shared memory, thread blocks) support thread blocks both kernels simultaneously. for more information, see this section in cuda c programming guide . as sgar91 commented, if these kernels share global memory, programmer's responsibility write correctly synchronized program avoid race conditions. if 2 kernels read same memory, there can no race condition.

working on connected application on windows mobile devices. application stores data locally in sql ce database synced mssql db using ms sync framework (via web service). now it's necessary sync mobile db 2 different server databases. i.e. sql ce database has tables a,b,c. tables , b should synced tables , b on serverdatabase1, , table c should synced table c on serverdatabase2. i'm thinking of creating second set of sync objects (syncagent , syncprovider) used syncing second database. wondering if there's other more convenient way this. that should work long you're synching same table same server. i.e., table c synched table c in serverdatabase2. the sync provider you're using has table contains "anchors" every table sync. anchors last sent , last received timestamps (if you're using timestamps). there's 1 row each table, cannot keep track of sync status of each table against multiple sync partners. a received anchor server dif...
