winapi - How to detect serial port sniffer? -

-

is possible detect if serial port being sniffed process running on windows?

we have application receives sensitive data cannot read other people. so, before opening serial port, need check if port being monitored.

we can use createfile windows api function open serial port exclusive access rights, if monitor runs before our call, can read communication (it opens serial port shared access rights, can open port @ same time). avoid this, attempt check if port being monitored , raise exception, warning user. possible this?

port sniffing requires filter driver, sysinternals' portmon utility. taking wrong kind of approach secure application. when can install filter driver, attacker has more enough privileges disable app , replace else of own making. trying detect , prevent information loss through app pointless, system has secured. serial port first thing you'll have lose, trivial tap wires.

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.
