i want animate simple calayer move , down in response incoming data (bars on graphic equaliser) the calayer should remain fixed along bottom , move , down height animated. can advise on best way achieve without having animate origin y coord height? if want layer grow , shrink bottom, should set own anchorpoint on layer bottom. anchor point specified in layers unit coordinate space both x , y range 0 1 inside of bounds, no matter size. yourlayer.anchorpoint = cgpointmake(0.5, 1.0); then animation, animate bounds (or better, can animate "bounds.size.height" , since height changing): // set new bounds of yourlayer here... cabasicanimation *grow = [cabasicanimation animationwithkeypath:@"bounds.size.height"]; grow.fromvalue = @0; // no height grow.tovalue = @200; // height of 200 grow.duration = 0.5; // add additional animation configuration here...

i understand .stream() , can use chain operations .filter() or use parallel stream. difference between them if need execute small operations (for example, printing elements of list)? collection.stream().foreach(system.out::println); collection.foreach(system.out::println); for simple cases such 1 illustrated, same. however, there number of subtle differences might significant. one issue ordering. stream.foreach , order undefined . it's unlikely occur sequential streams, still, it's within specification stream.foreach execute in arbitrary order. occur in parallel streams. contrast, iterable.foreach executed in iteration order of iterable , if 1 specified. another issue side effects. action specified in stream.foreach required non-interfering . (see java.util.stream package doc .) iterable.foreach potentially has fewer restrictions. collections in java.util , iterable.foreach use collection's iterator , of designed fail-fast , throw concurrentmodific...

i have 2 big numbers (<10^9) n , m . have calculate [(n-1+m)!]/[(n-1)!*m!] if answer big have modulus (10^9+7) . (ex : n%mod if n large mod). int mod = 1000000000+7; i calculated below. (i calculated upper half , bottom half separately) long up=1; (long = a+b-1; i>=math.max(a, b); i--) { up*=i%mod; } up=up%mod; long down=1; (long = math.min(a, b); i>0; i--) { down*=i%mod; } then print answer system.out.println((up%mod/down%mod)%mod); is approach correct. gives correct out put. i know (a*b*c)%d == [(a%d)*(b%d)*(c%d)]%d (correct me if i'm wrong) so there way calculate [a/b]%d ? (a/b) % c != ((a%c) / (b%c) % c) instead use recursive formula of binomial coefficient calculate modulus (n, k) = (n - 1, k - 1) + (n - 1, k) in case be (n - 1 + m, m) % mod = ((n - 2 + m, m - 1) % mod + (n - 2 + m, m) % mod) % mod use above recursion result.

i trying value "second row" in multidimensional array. have problems that. thought numbers stored sequentialy in memory tab[2][2] stored same tab[4] . seems wrong. this tried: int b[2][2] = {{111,222},{333,444}}; int = 0; for(;i < 100; i++) printf("%d \n", **(b+i)); the problem 111 , 333 result. there no 222 or 444 in other 98 results. why? the problem **(b+i) doesn't think does. evaluates to: b[i][0] as matt mcnabb noted , **(b+i) is equivalent to: *(*(b+i)+0) and since *(b+i) equivalent b[i] , expression whole can seen as: *(b[i]+0) and hence: b[i][0] since array has 2 rows, values of i 0 , 1 in bounds of array (that's 111 , 333). rest wildly out of bounds. what is: #include <stdio.h> int main(void) { int b[2][2] = { { 111, 222 }, { 333, 444 } }; int *base = &b[0][0]; (int = 0; < 4; i++) printf("%d: %d\n", i, base[i]); return 0; } output: 0: 11...

here 2 sql query on first query want use table , on 2nd query want join 1st query assume table e.g. first query: select sale.salesmanid, sale.companyname, sale.sellingprice sale inner join carmodel on (sale.companyname = carmodel.companyname) , (carmodel.size>10) ; second query: select salesman.salesmanid, salesman.name, sum(firstquery.sellingprice) salesman inner join firstquery on salesman.salesmanid = firstquery.salesmanid group salesmanid, name; how can ? in advance. if understand question correctly (although i'm not sure why you'd want way...): if object_id('tempdb..#firstquery) not null drop table #firstquery; select sale.salesmanid, sale.companyname, sale.sellingprice #firstquery sale inner join carmodel on (sale.companyname = carmodel.companyname) , (carmodel.size>10) ; select salesman.salesmanid, salesman.name, sum(firstquery.sellingprice) salesman inner join #firstquery on salesman.salesmanid = first...

i following along let's make rpg (c++/sdl2) - tutorials on youtube , stuck on let's make rpg (c++/sdl2) - part 35 continuation on collision ( https://www.youtube.com/watch?v=dlu6g2s3ta0&list=plhm_a02ntaavey-4ezh7p6bbosv-dka-0 ). i trying place transparent rectangle on sprites debug collision detection. not getting errors there no 1 piece of code can show you. can please shed light on went wrong. i'm new c++ i'm not giving up. thank time. i'm genuinely grateful. this code both header , cpp file of collision rectangle #include "collisionrectangle.h" collisionrectangle::collisionrectangle() { offsetx = 0; offsety = 0; setrectangle(0,0,0,0); } collisionrectangle::collisionrectangle(int x, int y, int w, int h) { offsetx = x; offsety = y; setrectangle(0,0,w,h); } collisionrectangle::~collisionrectangle() { //dtor } void collisionrectangle::setrectangle(int x, int y, int w, int h) { collisionrect.x = x + offset...

i noticed find surprising behavior ** (double-splat) operator in ruby 2.1.1. when key-value pairs used before **hash , hash remains unmodified; however, when key-value pairs used after **hash , hash permanently modified. h = { b: 2 } { a: 1, **h } # => { a: 1, b: 2 } h # => { b: 2 } { a: 1, **h, c: 3 } # => { a: 1, b: 2, c: 3 } h # => { b: 2 } { **h, c: 3 } # => { b: 2, c: 3 } h # => { b: 2, c: 3 } for comparison, consider behavior of single- * operator on arrays: a = [2] [1, *a] # => [1, 2] # => [2] [1, *a, 3] # => [1, 2, 3] # => [2] [*a, 3] # => [2, 3] # => [2] the array remains unchanged throughout. do suppose sometimes-destructive behavior of ** intentional, or more bug? in either case, documentation describing how ** operator meant work? i asked question in ruby forum . update the bug fixed in ruby ...

i don't know rdp, question may not make sense but: what correct way detect, in python, user logged server through rdp? would answer question: is there portable way current username in python? work on remoted log in?

first off, here's screenshots illustrate issue. i'm writing crowd-sourced lyric database web app on google app engine. have 2 text input boxes , text area lyrics. however, when grab data form add database entry, seems strip new lines. either that, or displaying them not working properly. here's code : class addsong(webapp2.requesthandler): def post(self): song = song() song.title = self.request.get('title') song.artist = self.request.get('artist') song.data = self.request.get('data') song.put() self.redirect('/') thanks taking time read this.

$str = 'test-test-test-test\\50-test-37447'; if(preg_match('/[a-za-z0-9-]/',$str,$matches)){ echo "<pre>true";print_r($matches);echo "</pre>"; }else{ echo "<pre>false";print_r($matches);echo "</pre>"; } it return true? wrong? it returns true because regex calls 1 character set (so t start first match). if want entire string made of characters, use: ^[a-za-z0-9-]*$ the ^ , $ markers indicate start , end of string respectively, , * means 0 or more of preceding "object". hence means entire string must made of 0 or more of character set you've specified. this causes \ character fail match in test string.

say have <div ng-repeat="item in scope.allitems"> <div ng-click="dosomething(...)"></div> </div> if want item upon click, 1 better option? option 1 use ng-click="dosomething($index) , have: $scope.dosomething = function($index) { var myitem = $scope.allitems[$index]; } option 2 use ng-click="dosomething(item) , have: $scope.dosomething = function(myitem) { // whatever } if doing item, pass in. way function doesn't need know array item belongs to: $scope.addcolor = function(car) { car.color = 'red'; }; if, on other hand, need modify array prefer pass in $index , save having loop through array looking match: $scope.deletecar = function(index, cars) { cars.splice(index, 1); };

i new on c#/visual studio , i'm having difficulty on running test methods. requires connect database server resulting of getting failed result since can't connect database. we tried modify connection string include our working credentials can connect database server app.config file encrypted. please see below screenshot of example encrypted line. how can modify that? as see think connectionstring encrypted outside project , pasted here. saying because imo encrypting connection string value , keeping key in plain text not possible within project. possible encrypt entire section within config file. check method using connectionstring. believe method might using form of decryption. use decrypt string, change values required, encrypt again , paste in above location. you can edit question include method using connectionstring can analyse , give better solution. hope helps.
