i know function fetchobject ( http://www.php.net/manual/en/pdostatement.fetchobject.php ) gives me next row object of specified class, want rows object of specified class, pdo has function or have manually??? thanks!! you looking pdostatement::fetchall : pdostatement::fetchall — returns array containing of result set rows example usage: $arr = $stmt->fetchall(pdo::fetch_class, $class_name, $constructor_args); if not need of objects in single array, find iterating through rows work well: while ($obj = $stmt->fetchobject($class_name, $constructor_args)) { // process $obj }

i working nsfetchedresultscontroller. want display in table view lions in zoo, lions to-many relationship of zoo. there thousands of lions, need batch size of 20. nsfetchrequest* fetchrequest = [[nsfetchrequest alloc] init]; nspredicate* predicate = ??? nsentitydescription* entity = [nsentitydescription entityforname:@"lion" inmanagedobjectcontext:context]; [fetchrequest setentity:entity]; [fetchrequest setpredicate:predicate]; [fetchrequest setfetchbatchsize:20]; how set predicate? have zoo object. need lions. as know nspredicate class specifies how data should fetched or filtered. nsfetchrequest has predicate property, specifies logical conditions under managed objects should retrieved. here's great example on how can use core data - http://nshipster.com/nspredicate/

for example, assume given list of ints: int_list = list(range(-10,10)) [-10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9] what efficient way find if given 2 values in int_list sum equal given int, 2 ? i asked in technical phone interview morning on how efficiently handle scenario int_list of say, 100 million items (i rambled , had no answer :/). my first idea was: from itertools import combinations int_list = list(range(-10,10)) combo_list = list(combinations(int_list, 2)) desired_int = 4 filtered_tuples = list(filter(lambda x: sum(x) == desired_int, combo_list)) filtered_tuples [(-5, 9), (-4, 8), (-3, 7), (-2, 6), (-1, 5), (0, 4), (1, 3)] which doesn't work range of range(-10000, 10000) also, know of online python performance testing tool? for integer a there @ 1 integer b sum equal integer n . seems easier go through list, arithmetic, , membership test see if b in set. int_list = set(range(-500000, 500000)) target_num = 2 de...

i using node.js forever run web service , website on machine. these services in files called app.js , site.js respectively i run multiple environments on same box , have been having devil of time keeping production or development instances every time start both services 1 seems kill other. it appears node js uses name of script index rather full path. thus if following commands run user@somehost:somepath/dev/someservice/$ forever app.js start user@somehost:somepath/dev/someservice/$ cd ../../prod/someservice user@somehost:somepath/prod/someservice/$ forever app.js start with hindsight kind of obvious issue stopping of serivces. when running user@somehost:somepath/prod/someservice/$ forever app.js stop both services stop. problem addressed using qualified path javascript file.
