So /prog/, I was thinking about all the mess of writing good software, with good programming environments and reducing portability effort.

Imagine you could just keep ONE language to rule them all, or ONE IDE, or ONE operating system. Everything may solve well... nevertheless it would be limitative for our awesome programmer minds... However ITT put your preferences about:
- language
- ide
- os
