Apocryphal ?? There but for the grace ..
I was told these ones years ago, If true my sympathies to all involved
An engineer working in a server room of a big banky\finance outfit leant against a wall, or stretched out an arm, ( we all know how cramped it can get working in a tight space.) and hit the emegency off kill switch for the room. Once order had been restored the great and good were gathered in the room to conduct the inquest and learn from it.
"Right so what exactly did you do..?"
" Well I just stood up stretched out and ..... Oh Shit.."
Outside a big disaster recovery centre Paddy was playing\prospecting in the car park with his company car, a JCB, laying new pipes or summat, As sometimes happens he found the mains duct and broke it killing the power. The UPS's kicked in and everyone waited for the standby gennies to start up, and waited and waited, Then some one realised the control cables and power feeds were in the same duct as the outside mains..
Finally a software one to spread the blame...
Another bank was planning a small mail shot to it's personal clients. aka high value individuals. The vellum was loaded into the printers, The delivery owls were put on standby. Unfortunately the test data used in the mail shot, as created by I suspect a lowly paid junior pogrammer 'leaked' into the production run.
So each letter began Dear RIch Bastard...
The current whereabouts of said programmer unknown.
