react native - Animate opacity based on view's position in scrollview -

-
i'm using react-native-swiper component allow user swipe horizontally between different listviews. animate opacity of these listviews @ full opacity when centered on screen , fade out when swiped left or right. have tried use onscroll event of parent scrollview (the swiper component) , using rctuimanager on listview components current position on screen: var handle = react.findnodehandle(this.refs['list']); rctuimanager.measure(handle, (x, y, width, height, pagex, pagey) but resulting animation really choppy , i'm guessing because uses onscroll event update opacity value. what best way achieve this? probably not relevant anymore since old question can use usenativedriver: true on scrollview , animate opacity based on scroll event performance. this blog post explains well

if folder structure x/y/a created 32 bit msi first , x/y/b created 64 bit msi. happen x , y ? msi id have? the uninstall order 1 matters. empty folders correctly removed if uninstall them backwards compared how installed, i.e. lifo . when install second msi, find x , y folders on machine. if gets uninstalled last 1 leave folders on machine if empty, because installation did not created them. (the installation of first msi created. when uninstall first msi before second 1 leave folders there because not empty, i.e. containing files installed second msi) you try using removefolders action .

matlab - Best way to flatten a 2D matrix to 1D when sliced from a 3D matrix variable -

i have 3d matrix in matlab store sequence of 2d arrays. i'm having find maximal value , row , column indices, pretty straightforward single variable holds 2d array in a = rand(10,10); [m,i] = max(a(:)); [i,j] = ind2sub( size(a) , ) the trouble cannot use syntax 3d matrix a = rand(10,10,3); [m,i] = max( a(:,:,1)(:) ); [i,j] = ind2sub(size( a(:,:,1) ), ) error: ()-indexing must appear last in index expression. i create temporary variable store 2d slice, i'd thought i'd see if there's better means of doing this, maybe making call reshape? there way use simple linearizing/flattening operator (:) in context? here's i'd do: [b i]=max(reshape(a,[],size(a,3))); [ii,jj]=ind2sub(size(a),i ); the limitation wont treat cases there more 1 max per 2d slice.

java - Some equal condition didn't work -

-
this question has answer here: what difference between == vs equals() in java? 22 answers why equal operator dosn't work in case : integer act0 = integer.valueof(ac.split("-")[0]); if (activite_alerte.getactivite().getidactivite() == act0)) { add_notif(profil, ao); added = true; break; } activite_alerte.getactivite().getidactivite() , act0 equals 439 didn't work other value work. you're using boxed integral type integer . java permits equality using == values in range -128 +127 since these "canned" boxed values, reference comparison work numbers in range. number - 439 - big. you should use .equals() instead boxed types. personally find 1 of pernicious aspects of java.

database - Filtering queryset with objects -

-
currently have foreach($this->friends $friend) { $user_ids[] = $friend->id; } $posts = post::wherein("user_id", $user_ids)->orderby("date_published", "desc")->paginate(15); seems okay , works fine, creation of array little weird. there way filter user objects themselves? example post::wherein("user", $this->friends) where $this->friends public function friends() { return $this->belongstomany("app\user", "friends_users", "user_id", "friend_id"); } $this->friends collection object has lists method creates array column, or associative array 2 columns. here's how use it. $posts = post::wherein("user_id", $this->friends->lists('id'))->orderby("date_published", "desc")->paginate(15);

c++ - How to speed std::vector access time -

how improve std::vector time? hi making software multivariable fuzzy k means cluster. work on big matrix´s 50.000 observations 10 variables. matrix not need grow o shrink or bounds check. make resize needed size, load items , make lot of access. first use: `std::vector< std::vector<double> > matrix(numclusters, std::vector<double>(numobs,0.0));` to element do: double a=matrix[i][j]; procces time of 20 minutes. then make: std::vector<double> u(numclusters *numobs,0.0); to element do: double a=u[i*numobs+j]; , time better. now want make question: more faster access: iterator+int std::vector<double>::const_iterator uit = u.begin(); double a= *(uit+index) pointer[int] std::vector<double>::const_pointer upt = u.data(); double a= upt[index]; or normal index access[int] double a= u[index]; greetings one thing try switch rows , columns. if have 10 × 50,000 matrix , lay down 1 row after another, operations on ro
