If your question is about:
Stack Overflow Server Fault Super User ... it is welcome here. No question is too trivial or too "newbie".
- StackOverflow (SO)
Programming questions, of course! As long as your question is:
detailed and specific written clearly and simply of interest to at least one other programmer somewhere ... it is welcome here. No question is too trivial or too "newbie". Oh yes, and it should be about programming. You know, with a computer.
- Serverfault (SF)
Server Fault is for system administrators and IT professionals, people who manage or maintain computers in a professional capacity. If you are in charge of ...
servers networks many desktop PCs (other than your own) ... then you're in the right place to ask your question! Well, as long as the question is about your servers, your networks, or desktops you support, anyway.
Please note that Server Fault is not for general computer troubleshooting questions; if you paid for that desktop hardware, and it's your personal workstation, it is unlikely that your question is appropriate for Server Fault.
- Superuser (SU)
Super User is for computer enthusiasts and power users. If you have a question about ...
computer hardware computer software … and it is not about videogames or consoles, then you're in the right place to ask your question!
I strongly feel that questions can be posted on multiple sites, if you expect to get corresponding answers from different communities. see herehere.
