jsp - Java Object creation vs. String parsing -

-

i'm working on migrating project jsp-centric using velocity. in many places jsp pages parsing strings display various things. makes jsp ugly , difficult maintain obviously.

i have modified controller class work me (i.e. creating list of pojos), iterating on pieces using velocity. have feeling it's going come heavy resistance.

i realize creating object comes overhead, makes our pages easier debug, write , use. besides fact separates ui core logic of occurring in background. not mention our appservers bored. database wincing in pain. see tenfold increase in users (which why developed parse strings in jsp & skip object creation) -- smells me of premature optimization.

what further arguments support claim should eat cost associated object creation?

  • object creation in java somewhat expensive, 15 years ago. java runtimes have improved lot since then. nowadays, java object creation faster in c++.
  • it never expensive decisive factor in basic application design.
  • doing things in jsp not mean no (or fewer) objects created. quite opposite, likely. jsps compiled normal java code creates lots of objects.
  • it sounds company needs hire @ least 1 person understands how java works asap.

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.
