Is very difficulty to use only free software in others places, but the mostly
of times is possible. The mostly of professors recommend many non-free
software and the mostly students without critic sense use it.
My cousin started the last month in civil engineering course and have the
same problem, but the professor recommended install DevC++(free software but
only for Windows). She uses Ubuntu since 2010 with the first computer of her.
I have the privilege to use only free software, fortunately. I'm a graphic
designer and use Inkscape, GIMP, Scribus, Blender and I use free software for
editing video and audio too, with Audacity, Ardour, Cinelerra, Kdenlive.
Don't give up, insist and show for your professors "this was made with free
software" =)
People are surprised when it does wonderful things with free software. The
people reaction is "Really? =O"
