a route hasmany departuredates . i'd create computed property collects value attribute of departuredates , returns string comma separates them , adds end date (which departuredate.value + route.duration ) of each. examples: "01.01.2015 - 05.01.2015" "02.03.2016 - 12.03.2016, 02.04.2016 - 12.04.2016" how can this? , departuredates.@each.value correct property use? app/route/model.js import ds 'ember-data'; export default ds.model.extend({ name: ds.attr('string'), duration: ds.attr('number'), departuredates: ds.hasmany('departuredate', { async: true }), departuredatetext: ember.computed('departuredates.@each.value', function() { // ??? }) }); app/departuredate/model.js import ds 'ember-data'; export default ds.model.extend({ value: ds.attr('date') }); not tested should work: departuredatetext: ember.computed('duration', 'departuredates.@each.

i've written 2 classes: function of first class cannot access private member of second class though function friend second class. found example msdn.microsoft.com there still error: cannot access private member declared in class b here code msdn : class b; class { public: int func1(b& b); private: int func2(b& b); }; class b { private: int _b; // a::func1 friend function class b // a::func1 has access members of b friend int a::func1(b&); }; int a::func1(b& b) { return b._b; }//the same error 1 below here int a::func2(b& b) { return b._b; } when write class a friend b there no error want have function want friend class b not whole class a is compiler fault or code wrong? i added declaration class b (called forward declaration of class ) @ top , compiles. need declare class b before use parameter in member functions of class a . here code -> #include<iostream> class b; class { public:

in model have: default_scope -> { order(created_at: :desc) } scope :ascending, -> { order(created_at: :asc) } in view: <ol class="notices comments"> <%= render notice.comments.ascending %> </ol> in model, when change default_scope -> { order(created_at: :desc) } default_scope -> { order(created_at: :asc) } , notices respond expected , display in ascending order instead of descending. however, when change scope :ascending, -> { order(created_at: :asc) } scope :ascending, -> { order(created_at: :desc) } , doesn't change anything. what's wrong code? when call order , adds component order clause. if have default scope , add ascending scope, end order by: order created_at desc, created_at asc the created_at asc ignored because unlikely there ties break created_at desc ordering. you want use reorder in scope replace order by: scope :ascending, -> { reorder(created_at: :asc) } this assumes ordering

in webstorm, have node application , hit debug , on load debugger stops on bunch of seemingly random lines in node_modules. can continue through 5 files until router/index.js file gets stuck on single line countless continues. i have no breakpoints in of node_modules files, obviously, , webstorm not show breakpoint. stops every time. solution has been mute breakpoints, wait app load, , unmute. sometimes, though, have re-add breakpoints if want checkbox check , able hit breakpoints. @ point have no issues. idea why it's getting stuck in node_modules no breakpoints? figured out workaround. chose "view breakpoints" , although points consistently stopped @ not listed, removed breakpoints, , can debug without stopping in random node_modules.

i using overlayskscene in scene kit. in skscene, using mask node crop skcropnode. mask node works when run on mac os x, when run on ios doesn't work. i think that's because ios ignoring sibling order , mask node shows behind skcropnode. when try set view.ignoresiblingorder = no; in skscene, crashes , says: [gameview setignoressiblingorder:]: unrecognized selector sent instance gameview subclass of scnview, understand scnview doesn't have property "ignoresiblingorder". how solve this? approaching wrong way? bug in scene kit when run on ios?

i need little solution refreshing listview after delete data database. realized can delete data database function of activity : helper.delete(string.valueof(editid)); adapter.notifydatasetchanged(); break; and in dbhelper : public void delete(string id) { string[] args = {id}; getwritabledatabase().delete(table_name, "_id=?", args); getwritabledatabase().close(); this code works deleting database , item, adapter.notifydatasetchanged(); listview refresh when closed application opened again. need way how refresh listview instantly. people used adapter.remove(position); , refresh instantly, call .notifydatasetchanged(); . not worked custom adapter. i used kind of adapter : class listadapter extends cursoradapter{ @suppresswarnings("deprecation") listadapter(cursor c){ super(mainactivity.this, c); } @override public void bindview(view row, context ctxt, cursor c) { // todo auto-generated method stub

i building stacklist. linked-list of stacknodes. each stack on stacknode of constant size (it int array). if stack full use malloc create new stacknode , append stacklist. i need implement function call int popat(int index); which should return element specified index. scenario: each stack has length = 10; stacklist has total of 5 stacks. number of elements in stacklist 10 per stack * 5 sets = 41 - 50 ( @ max can 50). want remove element @ index = 25. means @ 2ed stacknode of stacklist , 4th index in stacknode's stack. when remove 25th element, need push every element on top of down 1 element. my solution: copy elements on 2nd stack above 24th element 1 position down. { copy next stacknode->stack's first element end of current stacks //problem here select next stacknode } while ( linked list has stacknodes) problem: want shift elements in stack 1 position down. possible without iterating through array(a stack on each stacknode) because if hav

consider command: printf 'alpha\nbravo\ncharlie\n' | grep --line-regexp --quiet bravo grep sees 3 lines separated newline, , matches bravo line. consider command: printf 'alpha\0bravo\0charlie\0' | grep --line-regexp --quiet bravo my thinking tells me because have not used --null-data , grep should see 1 or 0 lines separated newline, , fail match bravo followed newline. not, succeeds first command, why this? this behavior was introduced grep 2.21: when searching binary data, grep may treat non-text bytes line terminators. can boost performance significantly. so happens binary data, non-text bytes (including newlines) treated line terminators. if want change behavior, can: use --text . ensure newlines line terminators use --null-data . ensure null bytes line terminators

this question came across in sedgewick's book. , on website, says answer 2, can't understand how achieve 2, because remove maximum need first exchange max element last one, decrease n, , sink last 1 down top place, takes logn exchanges. so, how achieve 2? exchange & remove-max: then need sink, l node, means need logn more exchanges. here's example 15 nodes. idea is: have sons of root large (let left 1 larger), other left descendants smaller right ones. swap twice. 100 99 90 9 8 89 88 7 6 5 4 87 86 85 84 you'll switch 84, 100 99, 84 , you're done. 2 swaps. for n > 3 , after first swap, there no way neither of 2 sons of root won't larger new root (otherwise wasn't heap begin with). you'll have swap. author meant write swaps, not items.

i wonder ui element should use large sets of text. eg between 200 - 1000 characters. i place text inside scrollview doesn't have ve scrollable or editable etc, want display text. so should use between label / text view / text field? thanks in advance. text views texts varying lengths, have scroll view of own. may consider using normal uilabel , setting "lines" property 0. know sounds strange, setting 0 tells label multi-line label. can use auto layout establish width of uilabel. grow down based on amount of text in it. text fields inappropriate displaying texts in cases; better user input.

i want build method accepts parameter type like void m1(type t) { // check type } and call m1(typeof(int)); i have no idea how check type in method body. i have tried if (t double) but giving warning the given expression never provided type (double) please me checking type of parameter. if want check exact type, can use: if (t == typeof(double)) that's fine double , given it's struct, can't inherited from. if want perform more is-like check - e.g. check whether type compatible system.io.stream - can use type.isassignablefrom : if (typeof(stream).isassignablefrom(t)) that match if t system.io.memorystream , example (or if it's system.io.stream itself). i find myself having think work out way round call goes, target of call usually typeof expression.
