animation - jQuery horizontal scrolling display -

-

i'm making horizontal scroller using jquery. have working using following

var wrapper = $('#wrapper'),     content = $('#scroll-content');   wrapper.bind('mousemove', function(e){      var wrapper_width = wrapper.width(),         content_width = content.width();         //wrapper , content width      var tmp  = e.pagex * (content.outerwidth() - wrapper.outerwidth()) / wrapper.outerwidth();     //calculate new left margin      content.css({ 'margin-left': '-'+tmp+'px' });     //set margin according      /*content.animate({         'margin-left': '-'+tmp+'px'     }, 30, 'easeoutsine');*/ });

every mousemove event calculate new left margin, slider spans 100% width of screen.

this works, have 2 problems. seems bad practise calling calculation on every mousemove event there hundreds. there better way, maybe using timers?

another question, when user first hovers slider jumps place, tried use animate slider slide down correct position, didn't seem work. (commented @ bottom)

any these problems great. thanks

you can use ben alman's throttle debounce plugin

and this:

$(document).ready(function() {      var wrapper = $('#wrapper'),         content = $('#scroll-content');      wrapper.bind('mouseenter mousemove', $.throttle(200, mousemove));      function mousemove(e) {         var wrapper_width = wrapper.outerwidth(),             content_width = content.outerwidth();         //calculate new left margin         var tmp = e.pagex * (content_width - wrapper_width) / wrapper_width;          content.stop().animate({             'margin-left': '-' + tmp + 'px'         }, 'fast', 'easeoutsine');     } });

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
