We in engineering are allowed to use whatever the heck we want so long as IT agrees that it is useful and safe and costs less than other options.
So we run a bunch of open source stuff. But the biggest one is Python. We connect arduinos and rpies to run complex machines. Meanwhile CAD runs on windows unfortunately along with all the bullshit spreadsheet, word and PowerPoint.
Linux is awesome and I see Windows day's numbered. So long piece of shit obsolescence software! One day you will be no more.
