package nan.salsa.goal.customview;  import android.r; import android.content.context; import android.graphics.canvas; import android.graphics.drawable.shapedrawable; import android.graphics.drawable.shapes.rectshape; import android.util.attributeset; import android.util.log; import android.view.view;  public class dayview extends view {      private static string tag="dayview";      private shapedrawable mdrawable;      public dayview(context context) {         super(context);     }      public dayview(context context, attributeset attrs) {         super(context, attrs);         init();     }      public dayview(context context, attributeset attrs, int defstyle) {         super(context, attrs, defstyle);         init();     }      public void init() {          int x = 10;     int y = 10;       mdrawable = new shapedrawable(new rectshape());     mdrawable.getpaint().setcolor(color.green);     mdrawable.setbounds(x, y, x + (width - (x * 2)), y + (height - (y*2)));      mdrawable.draw(canvas);     (int = 1; < 30; i++) {         boxdrawable = new shapedrawable(new rectshape());         boxdrawable.setbounds(x + x , y + (100 * i) , x + (width - ((x + x) * 2)), y + (100 * i) + 50);         boxdrawable.getpaint().setcolor(color.red);         boxdrawable.draw(canvas);     }        }      @override     protected void ondraw(canvas canvas) {         // todo auto-generated method stub         super.ondraw(canvas);         setbackgroundcolor(r.color.black);         mdrawable.draw(canvas);      } }

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.
