html - Prevent local caching of images, for security -

-
is there reliable way stop browsers caching image locally. not (just) freshness of image, rather concern sensitive images being stored on local drive. adding random url param img url suggested in similar questions not because ensures next request not last request in cache (at least understanding). need image never saved locally or @ least not accessible outside browser session if saved. you need send appropriate cache-control headers when serving response image request. see post information on standard ways in several programming languages. how control web page caching, across browsers? there alternate, , possibly more foolproof yet more complex, approach directly populate base 64 encoded images data directly img src attrbitute. far know not subject caching, there not separate http request made retrieve image. of course still need make sure page not cached, gets initial problem of serving appropriate headers primary html request.

Media query in HTML link is not linking to separate CSS file -

-
when use media query link multiple css files html link, full-size css file applies. i able media queries work within 1 single css file using: @media screen , (max-width: 700px) { body { /* style changes */ } however, want separate files each media query. here test code not work me: index.html <head> <meta name='viewport' content='width=device-width, initial-scale=1' /> <link rel='stylesheet' media='screen , (max-width: 700px)' href='mobile.css' /> <link rel='stylesheet' href='stylesheet.css' /> </head> <body> </body> mobile.css body { background-color:red; } stylesheet.css body { background-color:blue; } all files correctly named , saved within same folder. appreciated! this due order in linking css files. you need mobile.css classes override ones specified in stylesheet.css, include second. <link rel='stylesheet&#

ruby on rails - Assiging model reccord to more than one user -

-
i'm working on rails app , 1 of features lets give virtual gifts other users. one user gives gift(through gift model) user. 1 user giver(gift.giver) other user receiver (gift.receiver) my question how assign each gift 2 users, giver , receiver, can later call user.gifts_received list of gifts user received , user.gifts_given list of gifts user gave? is better have user.gifts instead of user.gifts_received , user.gifts_given? plan on using acts_as_follower gem let users see gifts given , received users follow. in past apps, when user created post, post belonged 1 user, assigned with: @post.user = current_user and how use acts_as_follower gem gifts 1 user user follows? i guessing gift model looks this: gift.rb class gift < activerecord::base belongs_to :giver, class_name: 'user' belongs_to :receiver, class_name: 'user' ... end so this, need make user model this, acts_as_follower stuff added: user.rb class user < activer

java - What is the time complexity of Collection.toArray()? -

-
what time complexity of method collection.toarray() ? o(n), if yes benefits offer on looping , individually assigning values in list array( beside nice , effort of course). because toarray() method abstract, speaking time complexity in general makes no sense. however, native implementations, complexity indeed o(n) . noteworthy collection subinterface of iterable . quite absurd implement iterable cannot efficiently iterated over. the fact implementation of toarray() kept open, leaving space optimizations. there may approaches faster building array using simple iteration (array copying, running in multiple threads...). however, default implementaion in abstractcollection uses exact approach mention in question.
