javascript - Trouble with google maps api v3 polyline and markers -

-

well im making gps tracking app , gps sending data database need fetch data , use api, app suposed draw route of 1 given car id. code 

for($i=0;$i<sizeof($losdatos);$i++) { if($losdatos[$i+1]['latitud']<>$losdatos[$i]['latitud'] || $losdatos[$i+1]['longitud']<>$losdatos[$i]['longitud']) { $script.="latarray.push(".$losdatos[$i]['latitud'].");"; $script.="lngarray.push(".$losdatos[$i]['longitud'].");"; $script.="codigos.push(".$losdatos[$i]['codigo'].");"; $script.="fechas.push('".$losdatos[$i]['fecha']."');"; $script.="velocidades.push(".$losdatos[$i]['velocidad'].");"; } }

once ive filled array call function of mine called route. parameters in function arrays

 route(latarray,lngarray,codigos,fechas,velocidades);   function route(lats,lngs,codigos,fechas,vs,weight) { var pointsarray=[]; //make new point each lat,lng  for(i=0;i<latarray.length;i++)     {     pointsarray.push(new google.maps.latlng(lats[i],lngs[i]));      //this next function adds marker , sets infowindow code,date , speed each one.     addmarker(lats[i],lngs[i],codigos[i],fechas[i],vs[i]);     }  //then send pointsarray polyline  var ruta = new google.maps.polyline({     path: pointsarray,     strokecolor: "#ff0000",     strokeopacity: 0.5,     strokeweight: weight});  ruta.setmap(map); }

the trouble polyline points , marker points not match 30 pixels away each other when supposed in same location

well problem solved had problem image size using thin

var marker = new google.maps.marker({             position: pos,              map: map,                 icon:'img/bluedot.png'  });

but seemed needed more specific did this

var icon=new google.maps.markerimage('img/bluedot.png',new google.maps.size(6,6),new google.maps.point(0,0),new google.maps.point(0,1));   var marker = new google.maps.marker({                 position: pos,                  map: map,                         icon:icon      });

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.
