Strictly speaking, all software is open source. You cannot hide the
source code to your application, only translate it into something less
human readable. Also, in almost all cases, preventing someone from
reading the code in the first place is a useless endeavor. Only where
something like trade secrets and industrial espionage is a factor does
hiding your source code make sense.
Thank you. But when a hacker who knows the internals of the software
gets access to the software in an End user's computer, and if he changes
the code after getting root access wont that harm the user's computer
and when he knows that the software is damaged or causing some trouble
wont he blame the makers
If a "hacker" has write access to your end user's files (including the
program you gave them), they can change it however they want. There's
nothing you can do there. There are some methods involving
cryptographically signed binaries and such, but there are always way
around it.
Like I said before, there isn't much you can do about things like this.
This is also not a problem unique to Ruby, all computer code suffers
from this "problem."
