Recently several posts asking for debugging help were cross-posted from Stack Overflow to Code Review after people suggested CR in their comments. Debugging is off-topic on Code Review. From our FAQ:

and your question is not about … Trouble-shooting, debugging, or understanding code snippets [emphasis added]

Please do not encourage cross-posts, especially off-topic ones. If you feel that a question belongs on Code Review, flag it for moderator attention and they will migrate it if necessary. Cross-posting and bouncing questions around the network will only raise tempers and keep questions from being answered.


  • Examples of such suggestions? I agree with the sentiment, but it's always nice to have examples instead of just anecdotal evidence. May 11 '11 at 14:16

    @Daniel I edited one in - I have two, but one was author-deleted on both sites. Also see meta.codereview.stackexchange.com/q/308/110 for more background.

    So yes, this is bad, but...two posts? I think every site in the network has gotten two bad migrations at some point May 11 '11 at 15:36

    @MichaelMrozek We only got one really bad migration from Super User to Gaming (and vice versa, haha), but I still made a post about it. I figure (and recommended this Michael as such), that when it comes to subjects that can reasonably be interpretted as on-topic for those unfamiliar with the site (debugging can be easily seen as a topic for a code review), being proactive and seeding the knowledge of the off-topic nature into the experienced Meta users early will go lengths to preventing it from developing into a serious problem.

Just to make it clear:

Code Review is for working code.

If the code in the question has (known) bugs, errors, problems, or otherwise is not working, it is not a code review question.

It has been two years from the last answer. I'll add an updated one.

Code Review is for working code whose working OP understands.

If you have working code that has been picked somewhere and you want to understand how it works then codereview isn't the place for you. Before posting you should know how it works.

I think this was needed as questions about "How X works" have come to codereview.SE incorrectly.
