How to GIve the Gift of Lumosity

Problem : My friend has a Lumosity subscription. But, she can't use it cause her laptop runs Win XP and is super slow. It may not be Windows' fault - it could be the hardware has quit -

Assuming Linux is the answer, what flavour of Linux will you use, considering the hardware ain't so great, to provide the optimal user experience - i.e., the computer shouldn't limit speed - so that Lumosity apps function flawlessly?

Unix Sort and Man

This reeks of "M$ and AAPL" trying to kill off linux :

Noticed the new distribution at work gives you the manpage in a new *ing window? Who the hell asked for that? The font is so tiny I have to do ctrl-scroll to magnify it. Goodbye productivity from getting where I want with keyboard only.

Please : how can I get a manpage to display in the terminal?

Your second challenge of the day :

How do you get a unix sort command to behave as before, but pretend it's reading Hebrew or Arabic? You get my meaning - start numbering fields from the right...

Please... How?

I tried these searches in vain :

how to prevent manpages from opening in new window
unix sort starting with fields from the right
how to unix sort based on columns starting from the right
