The complicated-looking script at the end of this article is in two parts. The first part detects the changes made when a data table is edited, and reports the changes as a plain-text logfile. It's a straightforward bit of shell scripting based on the diff command. The second part of the script…

Linux, HP and the avoidance of Windows

By

Having a TL;DR day? In a nutshell, I just replaced a 2011 HP Mini netbook with a 2014 HP mini-notebook. Both run Linux. Thank you, HP. The netbook I bought a 2011 HP Mini 110-3744TU in early 2012 (specs below). It came with Windows 7 'starter', which I replaced with CrunchBang Linux. The Mini is…
