How do I program, /prog/?

I have installed a distribution of GNU/Linux. I'm not sure what to do next...
Can I have some help here /prog/?

I really don't know how to articulate this any more without identifying myself. I was not an OS pioneer, but I was in the scene when IBM began selling their hardware to businesses. I was an OS programmer in that era studying, and improving the OS that was delivered. The OS was the fundamental layer of software that exist to support to application software. Stuff like text editors and compilers were part of this OS. Without this OS software, the rest of the system could not be controlled. The kernel was always one part of this system, the very core of the OS.
