For real though

easily solved. just leave a message to yourself in the past and tell him what he needs to do. give him motivation by showing what power he can have by going back in time. there, problem solved he will go back in time for other reasons but will do what you told him to do.
might work when what you want to do by going into the past is to save a loved one.

loved one died in a car crash.
dna test proves to be her.
make a time machine.
create flesh lab cultivated out of her dna and
go back into the past.
use your high tec to remote control the car into crashing with the flesh cloned from her.
bring loved one with you to the future.
you, in the past still find her car crashed with her "body" carbonized in it. you still have reason to create a time machine and do everything you did.
all problem have solutions. dont be an defeatist or you will never win

yes

Well memed

i want to learn php. i use c for everything but it's not suited for webdev, or so i'm told. php seems like a mature language with a lot of steam behind it. is it better than perl5, or should i learn perl5? perl6 is gimmicky junk as far as i can tell.
