...and then try to run SCADA system on Windows machines - just how many points of vulnerability do you need?
The utter stupidity of the beancounters who won't countenance anything other than Microsoft OS purchases, the beancounters trying to run technologically sophisticated enterprises without the slightest understanding of what the company does or how it does it - no wonder so many tech companies fail.
As long as we have beancounters valued more highly than engineers, these stupidities will continue. People need to understand that book-keeping is trivially simple - I can teach anyone to do it in an hour - and an "accountant" is just a book-keeper in a suit. They should be paid accordingly.
OTOH, engineers actually ADD VALUE to a company, and so should be well paid - ideally with some kind of profit-share as real motivation. They should also have the majority of input into technical products.
Thank goodness that Windoze is banned from most nuclear sites!
