Im quite new to Linux.
Currently Im doing programming with VB6 with MS SQL and SQLite.
Im familiar with Vb.NET and java.
I would like to consider Linux to devalop a commercial POS system.
What are the languages should I consider ?
Is there anything like MS Visual Studio?
How we design and develop applications in Linux?
Im happy to follow a Language similar to VB(ideally) or JAVA.
Which one is better Gnome or KDE?
