i testing facebook graph api v2.3 postman . while possible response putting access token in query string follow: https://graph.facebook.com/v2.3/me?access_token=my_access_token i wondering whether it's possible same thing http request headers, this: get /v2.3/me http/1.1 host: graph.facebook.com authorization: <my_access_token> cache-control: no-cache postman-token: <postman_token> based on similar question (i.e. how should client pass facebook access token server? ) on stackoverflow, seems should possible. any thoughts on this? edit: what raised interest that, when used api graph explorer provided facebook developers, seems there's no query string in sandbox either. how work? facebook api graph explorer use query string access token. @cbroe 's response. yes possible authorization: oauth accesstokenhere e.g. curl --header "authorization: oauth caac...zd" https://graph.facebook.com/me

i have invoice, there 2 columns: rate (column h) , quantity (column i). , there amount (column j). i need formula automatically multiply rate , quantity , show in amount . number of rows changing (added or deleted), formula should still work. the following arrayformula() spans row 5 ("books name") row 14 ("total price"), adding rows or deleting them should not problem: =arrayformula(if((c5:c14="books name")+(c5:c14="total price")=1,"",h5:h14*i5:i14)) however, since formula have reside in column j, following formula more useful: =arrayformula(if(c5:c14="books name","amount",if(c5:c14="total price","",h5:h14*i5:i14)))

i'm having problems approaching following problem. give context free grammar following language: {x#y | x,y in {0,1}* , |x| != |y|} what best way approach question? @ moment i'm using intuition solve questions these there useful techniques? i.e. think of pda language , derive grammer that? there method finding grammer g = , b using grammars , b? i'm struggling see how solve appreciated. thanks. using intuition valuable technique. solve more such problems, intuitions sharpen, gets easier. there's no formal technique convert description of language cfg (unless description maps onto cfgs, of course, set of production rules). not, in general, decidable whether language context-free (although cfgs must conform lot of constraints, possible prove language not cfg, semi-mechanically using counting arguments.) , not case intersection of 2 context-free languages context-free, there no procedure can take 2 context-free languages , generate cfg conjunctio...

it interesting question interview, failed it. an array has n different elements [a1 .. a2 .... an]（random order）. we have comparator c, but has probability p return correct results. now use c implement sorting algorithm (any kind, bubble, quick etc..) after sorting have [ai1, ai2, ..., ain] (it wrong) 。 now given number m (m < n), question follows: what expectation of size s of intersection between {a1, a2, ...， am} , {ai1, ai2, ..., aim}, in other words, what e[s] ? any relationship among m, n , p ? if use different sorting algorithm, how e[s] change ? my idea follows: when m=n, e[s] = n, surely when m=n-1, e[s] = n-1+p(an in ain) i dont know how complete answer thought solved through induction.. any simulation methods fine think. hm, if a1,a2,...,an in random order (as stated in question), sorting , probability of correctness of comparator c not matter. question reduced expectation of length of intersection of 2 random subsets, each of si...

code: document.addeventlistener('touchstart', function(e) { var ypos = e.screeny; console.log(ypos); }); ypos returns undefined in console. have chekced previous answers cannot find solution. why ypos returning udefined , not y-coordinates of mouse? any appreciated. for single finger touch, need retrieve touch object e.touches[0] . e.touches (or e.changedtouches , e.targettouches ) array, because spec supports multiple finger touch well. once object, use either screenx/y , pagex/y , or clientx/y , defined in spec . however, browser implementations may still vary.

is there way check if objects in list have same attribute google guava api? moreover, there way send more parameters predicate? let's said want filter objects string getting user, , want predicate use parameter when applying filter. you can create own predicate follows: class mypredicate implements predicate<myobject> { private final string parameter; public mypredicate(string parameter) {this.parameter = parameter;} boolean apply(myobject input) { // apply predicate using parameter. } } you can filter doing: iterables.filter(myiterable, new mypredicate(myparameter)); you should wary though performs lazy filter.

as per apple documentation, 1 use both wkinterfacetimer (local watch, counts down not trigger event when ends) , nstimer (to trigger methods when timer ends). so, have both nstimer , wkinterfacetimer in app interface controller. on simulator, on schemes when watchapp runs, nstimer & wkinterfacetimer keep counting down (as should) when watch either in awake or sleep mode (using simulator lock/unlock, instructed in apple's manual). however, on real physical watch, 2 timers behave differently upon watch display sleep (blackout) , awake states. sleep mode pauses nstimer of interface controller, wkinterfacetimer keeps counting down (as should). so, 2 timers run out of synch upon first physical apple watch sleep (nstimer pauses, wkinterfacetimer keeps counting down). seeking others experiences , whether implemented way keep both nstimer , wkinterfacetime in synch regardless of watch mode (sleep or awake). it seems store end time of countdown (for example, in nsuserde...

when try top 250 movies imdbpy returns empty list: >>> imdb import imdb >>> imdb_instance=imdb() >>> top250=imdb_instance.get_top250_movies() >>> top250 [] any idea? above code should return list of top 250 movies rated imdb found here . problem code returns empty array, , not list of 250 movies. i found problem. i did: >>>import imdb >>>dir(imdb) . dir() useful python function returns classes , functions under object. from there, found reason, way written, class imdbbase contains get_top250_movies() , not imdb . change from imdb import imdb from imdb import imdbbase , instance that. edit: point, @user3577702 pointed out abstract base class (oops). the mysterious empty list seems have been problem while. found question on google groups. according answer, the version in svn repository should work. however, no longer case. current commit doesn't work. i have started new question , maintaine...

i'm trying remove timer component list - foreach (timer timer in timers) { if (timer.tag.tostring()=="mytag") { timer.enabled = false; timer.tick -= ontimertick; timers.remove(timer); } } but gives error- collection modified; enumeration operation may not execute. any help? for unknown size should use list instead of array. try list<timer> timers = new list<timer>(); [edit] changed whole question new 1 after answer. can't remove item inside foreach loop. use duplicate list or iterate backwards: for (int = timers.count - 1; >= 0; i--) { if (timers[i].tag.tostring()=="mytag") { timers[i].enabled = false; timers[i].tick -= ontimertick; timers.removeat(i); } }

i have event model has many dateentry because event can have multiple datetimes . i have view see events date entries specific day. i've made class method in models/event.rb : def self.by_date(date) includes(:date_entries) .where(date_entries: { begins_at: date.beginning_of_day..date.end_of_day }) end and works fine. now on view loop on events grabbed query: @events.each |event| # whatever i looking way use date selected dateentry in loop. think have use activerecords joins method, have tried in many ways , when not getting error output still same. for clarifying, want in loop event.selected_date_entry_by_the_by_date_method.begins_at or that. first, in example date events same. set @date in controller , use in views. second, seems should doing things other way around. instead of finding events should finding dateentries , iterating on those.
