- Software development tools (IDEs, VCSs)
If you are looking for recommendations for software development tools and libraries, Software Recommendations is the right place. (Note that recommendations are off-topic on Stack Overflow and most of the other SE sites.)
If you have a question about (the usage of, a problem with, …) specific libraries and "software tools commonly used by programmers", Stack Overflow might be the right place.
Questions about the not-so-much-programming-related usage of software development tools (like installation, configuration, …), might also be on-topic on Super User and specialized sites like Unix & Linux, Ask Ubuntu, etc.
