i have 3 kendo().splitters: first vertical, dividing top 10% of screen bottom 90%. then, inside upper pane have horizontal splitter splits left 25% of screen rest; , in lower pane, have horizontal splitter splits left 25% of screen rest. end result 4 panes, top left 10% high , 25% wide, top right 10% high , 75% wide, bottom left 90% high , 25% wide, , bottom right 90% high , 75% wide. i don't know splitters have problem, when page first comes up, not line up. upper pane split, like, 23%/77% while lower pane split 25%/75%. 2 vertical bars not line up. first resize action take (with mouse) causes panes "snap" position where, now, line up. so, question is, how best done cause (otherwise) finally-rendered page 1 more recalculation of parts? assuming happens when resize page. have $(document).ready(function( ) , there should add in there? my environment i.e. 9, telerik controls, mvc4-razor.

why use stub given should testing real classes anyways? i know there cases don't want test other classes , not go through other associated class methods still think it's better use real methods. i can see benefit when want skip 1 method's other associated tasks , return end result used in tests are there other benefits though should considering? (in addition above think stub risky aswell since code can change evolves , may generate different output generating in tests) it depends on test performing. unit tests, testing single class, stubs beneficial. as example, assume testing class sends email when other object finishes did_it! operation: describe emailer context ".send_email" "sends email if object 'did_it!'" obj = obj.new emailer.send_email(obj).should == true # email sends end end end in case, if obj.did_it! super expensive operation, or fail intermittently, test have issues. however, ...

i have table x has auto-incremented id column primary key. have other tables a, b, c , d compliment info in table x. each of these have contain column references id table x. have done , in code (java) , have way of returning id of each entry table x , using when inserting other tables. working well. now, i've been advised assign id columns on tables a, b, c , d foreign keys because "it's right thing do". did that. now deleting rows table x takes incredible amount of time complete . insertion other tables takes longer too. please don't me wrong, know why foreign keys relevant specify relationships of tables on db. it's starting seem ceremonial rather relevant transactions becoming slower. questions: 1. worth lose performance in bid keep relationships officially specified though it's not necessary? 2. there way can speed transactions , still keep foreign key specifications. thanks. replies here how tables created. create tables sql: ...

i have api returns data following form (using tastypie): {"meta":{ "limit": 20, "next": null, "offset": 0, "previous": null, "total_count": 4}, "objects": [ { "id": 1, "name": "name1", "resource_uri": "/api/v1/operator/1", "short_name": "na1" }, { "id": 2, "name": "name2", "resource_uri": "/api/v1/operator/2", "short_name": "na2" }, ... ] } so thought have resource working, should have used: var operator = $resource('http://127.0.0.1:8080\:8080/api/v1/operator/:operatorid', {operatorid:'@id'}, { query: { method: 'get', transfo...
