html5 - Textures in CANVAS 2D Context -

-

just starting experiment filling canvas, , i'm trying apply texture object (the blobs blob example - http://www.blobsallad.se/). example using 2d context, , doesn't appear implementing webgl. information on texturing find uses webgl, , wondering how easy accomplish feat. there anyway incorporate texturing features of webgl canvas without rewriting code? summed up, guess question asking whether or not methods available 2d context available webgl context... if suppose change context , apply texture? if i'm thinking wrong or confused conceptually, please let me know.

thanks, brandon

i've experimented drawing image 2d canvas before using texture webgl canvas. works, performance horrible (it varies browser browser). i'm considering few other options refactoring it. wouldn't recommend more statically drawing image 1 or 2 2d canvases.

you can see example of craziness in lanyard/src/render/surfacetilerenderer.js in project at: http://github.com/fintler/lanyard

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.
