when safari restricted, [[uiapplication sharedapplication] canopenurl:url]] return true when call [[uiapplication sharedapplication] openurl:url]] nothing happened. i want check if safari restricted in settings - general - restrictions. this isn't possible in way there hackie way achieve anything. need is, when call safari set global timer before it, schedule few seconds (may 5 seconds), if safari open, app call - (void)applicationdidenterbackground:(uiapplication *)application , should invalidate global timer, in other case timer fire on scheduled time , you'll know safari couldn't open. can invalidate timer , show user appropriate message. p.s. comes mind when read question, not sure other possibilities or ways. there can more elegant way.

i have 6 png files want bundle 1 ico file. i'd use png2ico instead of web app convertico.org's web app . when ico produced using png2ico, quality of ico seems have dropped. below 2 images (100% view , zoomed in) comparing png2ico output (right) original png (left). is limitation of png2ico? can stop png2ico lowering quality? can recommend way of bundling 6 pngs 1 ico using terminal on osx? i emailed developer of png2ico , sounds png2ico supports 256 colors isn't acceptable needed. have since discovered imagemagick can convert , bundle multiple pngs 1 ico rob w's post here .

in matlab , numpy, can index vector array of indices , result of same shape out, e.g. a = [1 1 2 3 5 8 13]; b = [1 2; 2 6; 7 1; 4 4]; a(b) ## ans = ## ## 1 1 ## 1 8 ## 13 1 ## 3 3 or import numpy np = np.array([1, 1, 2, 3, 5, 8, 13]) b = np.reshape(np.array([0, 1, 1, 5, 6, 0, 3, 3]), (4, 2)) a[b] ## array([[ 1, 1], ## [ 1, 8], ## [13, 1], ## [ 3, 3]]) however, in r, indexing vector array of indices returns vector: a <- c(1, 1, 2, 3, 5, 8, 13) b <- matrix(c(1, 2, 7, 4, 2, 6, 1, 4), nrow = 4) a[b] ## [1] 1 1 13 3 1 8 1 3 is there idiomatic way in r perform vectorized lookup preserves array shape? you can't specify dimensions through subsetting alone in r (afaik). here workaround: `dim<-`(a[b], dim(b)) produces: [,1] [,2] [1,] 1 1 [2,] 1 8 [3,] 13 1 [4,] 3 3 dim<-(...) allows use dimension setting function dim<- result rather side effect case.

i'm working on swift application , have created links other views using presentviewcontroller can't figure out how pass variables. how pass variables new view? @ibaction func workoutpressed(sender: anyobject) { let storyboard = uistoryboard(name: "main", bundle:nil) let workoutview = storyboard.instantiateviewcontrollerwithidentifier("workoutview") workoutviewcontroller self.presentviewcontroller(workoutview, animated: false, completion: nil) //self.navigationcontroller?.pushviewcontroller(workoutview, animated: true) } thanks this easier think: don't need pass parameters because can access class variables of next view controller directly. that is, can this: workoutview.myvar = myval and, when view loads, myvar have value myval . (don't forget declare in workoutviewcontroller , though).

specifically, how swift memory management work optionals using delegate pattern? being accustomed writing delegate pattern in objective-c, instinct make delegate weak . example, in objective-c: @property (weak) id<foodelegate> delegate; however, doing in swift isn't straight-forward. if have normal looking protocol: protocol foodelegate { func dostuff() } we cannot declare variables of type weak: weak var delegate: foodelegate? produces error: 'weak' cannot applied non-class type 'foodelegate' so either don't use keyword weak , allows use structs , enums delegates, or change our protocol following: protocol foodelegate: class { func dostuff() } which allows use weak , not allow use structs or enums . if don't make protocol class protocol, , therefore not use weak variable, i'm creating retain cycle, correct? is there imaginable reason why protocol intended used delegate protocol shouldn't class p

[my first question of stackoverflow, so, hi!] i'm not sure of rules around place, have straightforward question follows... the sequences 23, 45, 23 , 23, 45, 56, 23, 23, 56, 45, 23 examples of palindromes. sequence 23, 45, 56 not palindrome. sequence 23, 32 not palindrome either. sequence of length 1 palindrome. given sequence of integers can broken parts such each of them palindrome. consider sequence 34,45,34,56,34. can broken 3 palindrome sequences 34, 45, 34 constituting first, 56 constituting second , 34 constituting third. can broken in 5 palindrome sequences each containing single number. we want determine smallest number k such given sequence can broken k palindrome sequences. #include<iostream> using namespace std; int main() { int n; cin>>n; int num[n]; for(int i=0;i<n;i++) cin>>num[i]; int c[n]; int co=0; for(int i=0;i<n;i++){ if(num[i]!=-1){ for(int

i trying update jlabel based on of inputs listed in title. can update jradiobuttons, , jcheckboxes, not else. doing wrong? here code: write code proper indentation. see 1 example code if(select == itemevent.selected) { totalamountowed += breakfast; //set total amount owed, , format money format. lblamountowed.settext("$" + moneyformat.format(totalamountowed)); } else totalamountowed -= breakfast; lblamountowed.settext("$" + moneyformat.format(totalamountowed)); in case lblamountowed.settext("$" + moneyformat.format(totalamountowed)) getting executed twice if enters in if loop. have add open , closing braces else part also. basically want execute both lines code in else part . beacuse did not add opening , closing braces in else logic , second lin

i'm working on self project. project let input day , program gives day of given date. here's array: string []days = {"sunday","monday","tuesday","wednesday","thursday","friday","saturday", "sunday", "monday"}; my condition: if(inputdate <= 6){ firstcase = yearscode[0] + inputdate + 3 - 7; system.out.println("january " + inputdate + " " + days[firstcase]);} i put day sunday , monday again because if input date 5<7 gives me arrayoutofboundsexception. i got algorithm here #6 : arrays don't care put in them, can have several copies of object in array if desire. however, solve problem more elegantly, can ensure index calculate never exceeds number of elements in array. this, can use modulo operator % firstcase = yearscode[0] + inputdate + 3 - 7; firstcase = firstcase % 7;

lucene popular text indexing tool ( http://lucene.apache.org/ ). installing lucene pythonic usage heck of work ( building pylucene on ubuntu 14.04(trusty tahr) ). whoosh python based indexing library ( https://pythonhosted.org/whoosh/quickstart.html ) supports full text search of lucene. for sake of users don't want hassle of installing pylucene use index i've built. is there way port lucene index whoosh? if so, how? other whoosh, lucene mongodb's gridfs , try replicate full text search in mongodb. but how port lucene index mongodb? possible? humanly, 1 can use luke ( https://code.google.com/p/luke/ ) or clue ( https://github.com/javasoze/clue ) read files is there other way export lucene index pythonically readable format? (without using pylucene)?
