i remote pi outside home network. problem apartment provides me wireless internet , can't access router enable port-forwarding. there way around this? dynamic dns service perhaps? i use vnc ssh and/or ftp. i use team viewer remote station behind nat without activating port forwarding in situation. need create account on team viewer application, , register target station's team viewer account. when away, please make sure open target station's team viewer , able remote target station first login team viewer account. once logged in have list of target station have registered. double click 1 of list , can remote target station. vnc or ssh not able work behind nat without activating port forwarding because router try open it's own port instead of target station.

using gnu find 4.4.2; confused @ how backspace .\ filename: find -name '*' -fprintf foobar "\b\b%h%f\n" how meant this? backspacing purely cosmetic issue in terminal , not delete characters data. find prints ./ because implicitly ask search . (by not providing path). you can use find -printf '%p\n' print path without search path. you can use find * , since makes search each (non-hidden) file in directory instead of directory itself. as funny aside, here's how you'd literally asked for: -printf '%h/\b\b%p\n' # not use! read context! this translates "print search path ( . ) , slash. print 2 backspaces make terminal hide them, , make programs consuming output choke. print path want." obviously better simplified "print path want", i.e. -printf '%p\n'

this question has answer here: can use variable name “type” function argument in python? 5 answers i've decided coding exercises @ coderbyte.com , right in first exercise (reverse string) found this: def firstreverse(str): even though works, don't think it's idea use built-in type name parameter. think? know it's kinda silly, it's first question @ stackoverflow! =) in function definition, str supposed string , not built-in function str() . when this, overwriting built-in function, won't able call str() inside function f , can still using outside. because scoping, overwriting in local scope of f : def f(str): print str(123) # raise error, because 'str' not callable (i.e. function) anymore f("some string here") print str(123) # ok this common mistake, sooner learn avoid it, sooner become programmer.

i think i'm missing conceptual , fundamental wcf channels. how there's channel stack of protocols on either side going top level tcp or http down wire-level transport protocol. what don't means "open" channel , how channel stays "open" , how channel "faulted". what happening on client , service makes channel "open"? open seems sate it's hard me conceptualize state in stateless service. make sense? your service may stateless, many networking protocols not. from understanding state changes state machines , channels objects deal communication, example sockets, present state machine state transitions relate allocating network resources, making or accepting connections, closing connections , terminating communication. channel state machine provides uniform model of states of communication object abstracts underlying implementation of object. icommunicationobject interface provides set of stat
