How to setup your Ubuntu @CERN

CERN Hacks

This Gist is a guide on how to setup your computer at CERN with Ubuntu 14.04 LTS. Last tested by myself on a brand new computer on 18/11/2014, proof tested by @Alea88.

NOTE (26-02-2015)

With the kernel upgrade from 3.13.0-45-generic to 3.13.0-46-generic AFS stops working: https://bugs.launchpad.net/ubuntu/+source/openafs/+bug/1423151

Type this to check your kernel version:

Method to analytically approximate the MPV of the Landau distribution, e.g. for charge deposited.
When filling histogram, fill with Moyal distribution instead of charge directly:
qMoyalvsxmym->fill( xmod, ymod, exp(- Q0 / 3.5) );
where 3.5 is a normalization factor corresponding to <>
After filling the histogram, rebin using
for(Int_t i = 1; i <= h->GetNbinsX(); i++) {
