Is using an API always preferable to scraping? -

-

i looking large amount (>100k @ least) of data web 2.0 sites research project. thinking of using exposed api data, scrapping work better in case?

the api (less work compared writting scraper), have no idea how time need collect data, considering there time/call limit. i'm not saying there no limit in scraping though; curious better way of getting job done.

if site provides api, use it.

it's simpler, generic, , legal. if site kind of popular, find wrappers language you're using.

of course, if develop scraper, won't have limitations, maybe site doesn't allow being scraped, , that's why have api users/developers.

let's see... moral thing. if want, can obtain amount of data several times without being blocked. can change user-agents, change ip after n requests (of course, of programatically), , tricks cookies, that's not idea. mean advice of not using website scraping not because of getting banned website.

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.
