Given a decompressed gzip file, is there any way to recreate the exact original gzip file?

Definitely no for gzip, unless you also know the tools and parameters involved (and maybe even then).

Definitely no for gzip, unless you also know the tools and parameters involved (and maybe even then). Considering the trade-offs involved, I don't see why this would be desirable, as the user couldn't balance different concerns. I would not want to have the same parameters used to do gzip on the fly on a webserver for content-encoding or transfer-encoding as I would for zipping up a massive archive while I am happily in the pub letting the machine do its job overnight.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
