I work remotely via a VPN and am often plagued by frozen SSH sessions (especially if I step away from my desk for any length of time). I always used to close the shell/terminal - which is a bit annoying. Then I came across the solution below, just type enter (in the frozen shell) then tilde and period/full-stop and you drop out of the ssh session.
This is mainly somewhere for me to dump interesting tidbits of tech info. Stuff that I may forget but will need again in the future. For a proper blog, visit my electronics blog (http://www.fangletronics.com) or my wife's pre-school crafty blog (http://www.filthwizardry.com).

Generating random numbers in bash
I wanted to assign each member of a training set to a cross-validation fold. I wanted to do this in a bash script and so ended up using something like the following:
This script generates n numbers selected randomly in the series of integers from 1 to m. In this case m represents the number of cross validation folds.
You could generate a random CV fold assignment like so:
Depending on your input file format of course.
