android - Factors to consider to choose among client-side application or web application -

-

it seems there 2 choices develop solution android platform : client-side application , web application.

according http://developer.android.com/guide/webapps/index.html

the approach choose application depend on several factors...

but tutorial doesn't mention factors should consider. may know factors need consider? or in word, what pros , cons of each solution?

p/s : when talk web application, mean solution provided http://www.phonegap.com/ well. seems able pack html, javascript , css single package looks native app. (i haven't try out)

go native if...

  • you need capabilities cannot achieved such accelerometer
  • you need run processes in background, such polling servers updates, downloading information in background, listening changes made on device
  • you need know orientation of device, such locking user portrait or landscape or if need alerted when changes
  • you need access system services such sound manager
  • it's important have launcher icon
  • you need high performance stuff (image editing, playing preloaded sounds, etc)
  • you need absolute control of caching strategies performance reasons. example, if need download information web or preload lot of images, want control on browser doesn't flush stuff without control , have make user wait things download again , again
  • (via greg's comment) want app work while offline

go web app if...

  • your requirements light , want can cross platform compatible (same app running on iphone, etc)
  • (via greg's comment) don't mind app require active network connection (will not work on subway!)

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.
