The list wasn't meant to scare you off (hint: say you wasn't scared). 
Rather, serve as a sketchy plan. Also, no need to become an expert in any 
of this. It is more about knowing your way around, so you know there is 
some docs to peek into or can ask better questions on the net.

BTW, I think many if no all of the things you might learn, you will 
quickly find yourself using them one way or another on a daily basis.

For example, it was my long habit to run Python interpreter soon after 
logging in and use it for all kinds of quick calculations. Until one day I 
started using Common Lisp interpreter for this - but that's another story. 
Python is - I guess - one of the easiest to learn of contemporary 
mainstream languages. You can have a glimpse of it from some youtube 
videos, like those:

I forgot to mention, last time I used VBox (some, say, two years ago) it 
was possible to make more than one such virtual PCs, connected via virtual 
network, running different OSes etc. So, once you get comfortable with one 
Linux, you might want to make a virtual Beowulf cluster first, to feel the 

Also, you can make use of cloud services with knowledge of VBox. I think 
Amazon Cloud accepts images made with it, so you can have a cluster in 
this way, too.

So all in all, this might be lots of fun.

Ok, enough of this.
