for example, there following piece of code: $scope.posts = post.query({ user_id: $stateparams.user_id }) how construction work? when js execute line posts may empty, after time server side return posts , view render lot of posts. how 'query' function may return value in future? don't understand it, because ajax call asynchronous, , don't send value in function. please, describe moment. thanks. i know promises , $q, don't understand how works here. internally executes asynchrnous operation , returns reference empty array. when asynchronous operation has finished populate array elements. $scope.posts reference same array, containing elements. simple example implementation: app.factory('post', function ($timeout) { var query = function (selector) { var result = []; // asynchronous operation $timeout(function () { (var = 0; < 5; i++) { result.push({ id: }); } }, 3000); return result;

background i'm creating c# application runs status checks (think nagios style checks). what ideally want c# application @ specific directory, , compile/execute scriptcs scripts within it, , act on results (send email alerts failing status checks example). i expect script return integer or (for example) , integer indicate weather status check succeeded or failed. values returned c# application. 0 - success 1 - warning 2 - error when first tasked thought job mef, vastly more convenient create these 'status checks' without having create project or compile anything, plopping scriptcs script within folder seems way more attractive. so questions are is there documentation/samples on using c# app , scriptcs (google didn't net me much)? is use case scriptcs or never intended used this? would have easier time creating custom solution using roslyn or dynamic compilation/execution? (i have little experience scriptsc) i found easy examples on how th

i writing small script guesses numeric passwords (including ones leading zeros). script works fine having trouble understanding worst case time complexity algorithm. insight on complexity of implementation great, thanks. def bruteforce(ciphertext): plen in itertools.count(): password in itertools.product("0123456789", repeat=plen): if hashlib.sha256("".join(password)).hexdigest() == ciphertext: return "".join(password) first, it's possible you're going find hash collision before find right password. and, long-enough input string, guaranteed . so, really, algorithm constant time: complete in 2^256 steps no matter input is. but isn't helpful when you're asking how scales more reasonable n , let's assume had upper limit low enough hash collisions weren't relevant. now, if password length n, outer loop run n times.* * i'm assuming here password will purely numeric. other

what best way compare more 2 objects all.equal() ? here's 1 way: foo <- c(1:10) bar <- letters[1:10] baz <- c(1:10) # doesn't work because all.equal() returns character vector when objects not equal all(sapply(list(bar, baz), all.equal, foo)) # works mode(sapply(list(bar, baz), all.equal, foo)) == "logical" #false bar <- c(1:10) mode(sapply(list(bar, baz), all.equal, foo)) == "logical" #true update: @brodieg pointed out one-liner above tells whether objects equal or not, whereas all.equal() tells isn't equal them if aren't equal. here option: objs <- mget(c("foo", "bar", "faz")) outer(objs, objs, vectorize(all.equal)) it's better yours because detect when bar , faz same, when foo isn't. said, lot of unnecessary comparisons , slow. example, if change foo letters[1:10] get: foo bar faz foo true character,2 character,2 ba

i have set of distinct values. looking way generate partitions of set, i.e. possible ways of dividing set subsets. for instance, set {1, 2, 3} has following partitions: { {1}, {2}, {3} }, { {1, 2}, {3} }, { {1, 3}, {2} }, { {1}, {2, 3} }, { {1, 2, 3} }. as these sets in mathematical sense, order irrelevant. instance, {1, 2}, {3} same {3}, {2, 1} , should not separate result. a thorough definition of set partitions can found on wikipedia . i've found straightforward recursive solution. first, let's solve simpler problem: how find partitions consisting of 2 parts. n-element set, can count int 0 (2^n)-1. creates every n-bit pattern, each bit corresponding 1 input element. if bit 0, place element in first part; if 1, element placed in second part. leaves 1 problem: each partition, we'll duplicate result 2 parts swapped. remedy this, we'll place first element first part. distribute remaining n-1 elements counting 0 (2^(n-1))-1. now can partition s

c++: class destructor do? suppose have object "myobject", , has several members follows: int a; float b; yourclass yourobject; void hismethod(); from read, memory allocated "myobject" order. once destructor called, happened? after destructor called, before object destroyed, read, can still access (a) object "myobject". (b) member yourobject (c) member hismethod() can still access members? undefined behavior? many c++ books not talk more details on it. can find more details on it? because details can me understand many c++ rules "not manually call destructor unless after placement new". [update 1] raise question because saw post: what empty destructor do? poster gives example below: #include <iostream> #include <set> class { public: std::set <int> myset; }; int main() { object; object.myset.insert(55); object.~a(); object.myset.insert(20); std::cout << object.myset.size(); } the poster get: &quo
