compilation - Linux vs Solaris - Compiling software -

-

background:

at work i'm used working on solaris 10. have sysadmins know they're doing , can out if required.

i've compiled things apache, perl , mod_perl source without problems.

i've been given redhat server play , hitting problems. sysadmins out sick @ moment.

i keep hitting problems regarding ld_library_path when building software. @ moment test purposes compiling home directory, don't have root, or permissions install anywhere else.

i plan on having area under /opt install into, on solaris, i'll need out sysadmin around create us.

my .bashrc had nothing ld_library_path i've been appending things stuff built (e.g. ffmpeg source). i've been reading , apparently isn't way go, it's not reliable or something. don't have access ldconfig (permission denied).

now quetions:

what best way build applications under linux won't break? creating entries under /etc/ld.so.conf.d/ ?

can give brief overview of ld_library_path does?

from ld.so(8) man page:

  ld_library_path           colon-separated list of directories in search elf           libraries @ execution-time.  similar   path  environment           variable.

but honestly, find admin. become 1 if need be. oh, , build packages.

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.
