Not quite!
I wrote my own rsync-like-toolset before rsync itself was released (far too late, when you think of it!), and I immediately loved DropBox.
Maybe because I am dev, AND I am ops, or maybe because (unlike DropBox) I am not sharing folders with my mother, but more likely, because I'm an idiot (everyone tells me "Catcher in the Rye" is great - and after having read it every 3rd year for nigh on 30 years, I still don't get it), but I don't really understand the appeal of docker.
Sure, I can use it, because you kind of have to these days, and I don't really find it objectionable, but it seems like there is a whole lot of "something there" that I'm missing. At this point, I'll probably never understand the benefit of. It won't be the last tech ritual I will have to endure before I die...
I’m going to keep trying, probably, because so far it’s one of the only big classics I haven’t liked. Anyway, maybe we’re both idiots!
I started in my mid-teens. I was told: "It changed my life!".
I've read it every three years or so (even for the decade-plus that I've lived out of the US, once in Japanese!), and ... I just don't get it.
I probably don't get Moby Dick either, but I find it to be remarkably funny, and not a whiney teenager, so I'm going to give it a pass.
Thanks for the comment. I have a bit of a hang-up about how much I don't get "The Great American Novel" (as a born-and-bred rural American, I should get those, you know? :-) )
Probably the same people who said Dropbox brings nothing new over rsync. Making something easier and bringing it to more people (two halves of the same thing) is a BIG value add. Often the majority of the value.
