i have liquid flexible layout 3 columns, on left 200px , right 200px if page support infinite width set standard 2015 center column main content. 800px nobody uses question if 1000px old , uses 1300px or recoomend? i tested 1000px width , works fine on many cellphones , tablets (horizontal view) seems old notebooks , netbooks supports 1300px. what recoomend , screen resolution popular on year 2015 including old devices? i use 1200px (with padding goes 1180px), 1300px works fine, too. make sure website responsive, no 1 have problems.

this thread gave me idea how structure code: scala-way handle conditions in for-comprehensions? the part in question: // first create json val resultfuture: future[either[failure, jsresult]] = { userres <- userdao.finduser(userid) user <- userres.withfailure(usernotfound).right authres <- userdao.authenticate(user) auth <- authres.withfailure(notauthenticated).right goodres <- gooddao.findgood(goodid) <- goodres.withfailure(goodnotfound).right checkedgood <- checkgood(user, good).right } yield renderjson(map("success" -> true))) this lines not understand: user <- userres.withfailure(usernotfound).right authres <- userdao.authenticate(user) the userres.withfailure(usernotfound).right mapped userdao.authenticate(user) . create new either future on right, correct? how can val resultfuture: future[either[failure, jsresult]] be of type. think instead of jsresult there should future. can explain me? edit

is bad practice have itemid configuration on class definition (instead of instantiation)? is there official documentation backs or matter of opinion? or maybe there logic i'm missing makes evident bad practice. ext.define('someapp.view.somefolder.myspecialcomponent',{ extend: 'ext.panel.panel', itemid: 'specialcomponent' // ... }); because understand if there more 1 instance , use itemid selector both instances. let's know won't have more 1 instance @ time , let's instantiation can occur in 3 different places, don't want add itemid's in 3 different places , don't want itemid's different. so there official posture using itemid configuration @ class definition? from docs of ext.abstractcomponent.itemid : an itemid can used alternative way reference component when no object reference available. instead of using id ext.getcmp, use itemid ext.container.container.getcomponent retrieve itemid's
