javascript - Markers Appearing at Random Times -

-

i trying create map 3 different markers, each appearing @ random time. think problem asynchricity.

the test url here , map shows towards bottom of page: http://www.comehike.com/hikes/hike_carpool.php?hike_id=125

does know doing wrong?

thanks, alex

you mean see markers drawing @ different time, e.g. @ beginning see red one, yellow, , blue one. next time load page notice blue marker showing first, yellow , red one. question right? if yes, not care :) depends on network connection, server loading etc. e.g. @ net tab of firebug, first time got:

enter image description here

so browser started requesting smile.gif , car.jpg @ same time, after while marker_sprite requested. see maps.google.com served request faster (though request started later). server (comehike.com) processed request car.jpg (though big one, 1.3kb), , comes smile.gif (though size 174b , first requested image).

next time pressed f5 , got images browser cache, browser sends requests see if not changed:

enter image description here

notice, browser started requesting information car.jpg quite early, due connection time, , waiting result took lot (though cached, browsers waits confirmation). again maps.google.com processed request faster comehike.com.

so not ajax, depends on when browser request image, , how fast server process (and depends on queue etc...).

if want markers shown @ same time, need use css sprites , combine marker images one. have there (any article good):

  1. css sprites: are, why they’re cool, , how use them
  2. css sprites: image slicing’s kiss of death
  3. the mystery of css sprites: techniques, tools , tutorials

this way have 1 image instead of three, when loaded browser display markers (at least won't notice there delay between marker drawing). hope explains , helps.

magically formatted comments change reported line number of javascript errors in browsers; this: //@line n "f" n line number , f file name. unfortunately, //@line appears ungoogleable. know there documentation on feature, , browsers support it?

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.
