Take a good look at any new stuff to determine what it is good for (if there's any). Keep your results in mind, and go back to your old stuff.

Then, if you have a problem that can be solved by the new stuff, go and learn it, otherwise why bother?

Honestly I don't see that huge influx of novelty people keep claiming is here. Yes, specialized knowledge is advancing rapidly, but mainstream tools are quite stagnant. (E.g. I'm avoiding learning how to script Docker for near a decade already.) It may be a matter of changing your focus from products into technologies (what does require deeply learning a few techs).

Quite an accomplishment, given that Docker is four years old. You're twice as effective in not using Docker as me.

Avoiding Docker as well like I avoided Ruby and mocking frameworks. Some things just don't feel right.

[marcosdumay]

What? I remember reevaluating it so many times. Was there some other famous container product before it?

[dozzie]

Well, four years is what Wikipedia states.

I don't think there was anything as prominent as Docker on cgroups that was as old as ten years, since cgroups are that old. LXC was started eight years ago, and then Docker hijacked the subsystem and nomenclature.

But maybe you were thinking about some predecessor, like Virtuozzo/OpenVZ or Linux VServer? Those were never as popular in general public as Docker, but they had their mindshare, especially in some circles.
