i've finished working on mvc web api service, purpose show data microsft analysis cube, , return json objects. so lets have object loaded cube , returned service json: public class person{ public string name {get;set;} public double balance {get;set;} } now on mvc app makes request service create exact same class, can desirealize json. can see if person object extended lastname atribute, have add exact same attribute in app too. there architecturs / patterns avoid creating exact same class/object on both app , webservice? maybe create separate library contains nessesary objects, , parse in dll webservice , app? or there other way? @ahmed right. should create separate models or view models expose data per tier. there security implications when overpost data endpoints. data may highly confidential salary, example, , show in wrong places. may use automapper map data between tiers. looks @ least addresses problem trying solve: https://github.com/automapper/aut

ios - How to sort array based on another arrays position? -

i have tableview style being right detail . therefore have 2 arrays , 1 textlabels data, , other detailtextlabel . there 2 "sort by" options. 1 sort textlabels data, , second sort detailtextlabels data. when sort first array ( textlabels array ), second array (detailtextlables array ) have sorted based on first array`. i know how sort arrays , how can sort 1 array based on another? here's how sorted array : (it's array of dates . firstarray.sort({ (a, b) -> bool in a.earlierdate(b) == }) it's bit messy, can use enumerate work indices , elements @ same time: array1.enumerate().sort { return $0.element < $1.element }.map {$0.element} array1.enumerate().sort { return array2[$0.index] < array2[$1.index] }.map {$0.element} but it's simpler/easier 1 array. struct item { let prop1: int let prop2: string } var array = [ item(prop1: 1, prop2: "c"), item(prop1: 2, prop2: "b"),

algorithm - Amortized Cost Analysis with a Stack -

suppose have stack backed n-element array cost 1 push, cost 1 take element out of array, , cost of resizing array number of elements moved. 1) every time stack becomes full, copy on current n elements new array that's 1 element larger before. text claims series of n pushes result in total cost of: 1 + 2 + 3 + ... + n why this? array starts off n = 1. i push , stack full (cost 1) increment size of array (n = 2 , cost of 2) push , stack full (cost of 1) increment size of array (n = 3 , cost of 4) ... what missing? 2) suppose double size of array every time stack full. have series of n pushes starting 1-element array: i push , stack full (cost of 1) double array size , copy 1 element on (cost of 2, n = 2) push , stack full (cost of 1) double array size , copy 2 elements on (cost of 4, n = 4) ... does analysis right? for series of n pushes, yield 1 + 2 + 1 + 4 + 1 + 8 + ... + 1 + 2 ^ (n/2) everything sounds reasonable me: 1) let's start empty s

javascript - My JQuery validation plugin behaves strangely with checkbox inputs -

i wrote own general use validation plugin(s) take function check if input valid , callback each of cases input determined valid , invalid first function. basically, plugin consists of 2 functions, '$.fn.validation()' bind object containing validation logic , success/failure callbacks element , '$.fn.validate()' either invoke validation object, or if new object passed in use new object 1 instance. implementation of plugins , a jsfiddle demonstrating issues described below can found here. my issue while text input , texareas seem work in cases, depending on how elements, such checkbox inputs, selected, elements may not validated despite being in set of elements returned jquery element for example, following selector not result in check boxes being validated $('input, textarea').validate(); however more specific selector result in checkboxes being validated $('input[type=checkbox]').validate(); again, please checkout jsfiddle have replic

arrays - How to find a row or column under specific conditions in a matrix in R -

this question has answer here: given value of matrix, getting it's coordinate 2 answers for example, if have matrix or array following format how can find index of rows or columns have numbers between 10 20 inside ? m = array(c(1,1,12,34,0,19,15,1,0,17,12,0,21,1,11,1), dim=c(4,4)) and, also, not allowed use or while loops this. thing matrix or array may have more 2 dimensions. if method can apply multi-dimensional matrix or array, better me. thanks. instead of trying find index of qualified single elements, need find rows or columns in elements between interval. in example, hope have result telling me row number 3 row numbers within row between 10 20. use which(..., arr.ind = true) . here assume between means 10 , 20 non-inclusive which(m > 10 & m < 20, arr.ind = true) # row col # [1,] 3 1 # [2,] 2 2 # [3,] 3 2

c++ - Ordered associative containers of pointers -

this question has answer here: are pointers allowed keys in ordered stl containers? 4 answers is okay practice define ordered associative containers of pointers (either built-in or class-type ones) despite fact that, far can tell standard, relational operators on (non-array objects et al.) pointers undefined? from 5.9 of c++11 standard: if 2 pointers p , q of same type point different objects not members of same object or elements of same array or different functions, or if 1 of them null, results of p<q , p>q , p<=q , , p>=q unspecified. since ordered containers (map, set, multimap , multiset) use < operator default provide total order compiles fine create set of pointers. again if relational operators pointers unspecified p<q , p>q both test false or true meaning may not idea ordering of set . would've accepted bad id
