Jonathan: Perhaps instead of civil engineer / crofter I should have joined the ranks of International Rescue. Two damsels in distress have been saved from outrage or calamity, all whilst sat at my desk and sipping a mid-morning coffee.  In Wales, Becky was wrestling with unknown powers lurking in the dark corners of her computer, whilst here in Scotland (well admittedly just across the office – but, really, I could have been anywhere in the world) Denise was saved from a mistaken over-write (which in my experience is by far the most common means that data is lost, not simply the deletion of a file) which was made at some time in the past, unknown. So world saved by 1045hrs ; so can I take the rest of the day off?
