I am an engineer working for a large firm.
I have worked on projects using RT Linux. I prefer Linux as a desktop tool, though my company doesn't. There was some traction at one time for Star office, but alas, the IT weenies killed that plan. What do they know, except Novell over MS Windows networking (ptui! ptui!)
I am currently working on a meglomaniacal plan to do something about software patents on a low political level.
