How to list both journals and conferences on your CV when you have worked in two fields with different publication cultures? I used to be in a field where journals were much more prestigious than conferences, so I kept journals and conferences in separate sections (assuming that people would care a lot less about the conferences).  Now I have switched to computer science, where conferences are the main venue of publication, and my only first-author paper is now a conference paper.  Do I still keep journals and conferences separate?  It feels weird to put my only first-author paper in the same section as a random poster presentation my coauthor gave.

I'm also thinking of having one section for "publications," and listing all the papers reverse-chronologically, except for the non-important conferences, which I'd put at the end.
I work with this situation myself right now, as I am active simultaneously in two fields with these opposing publication cultures.  This is further complicated by the fact that some of the publications I am most proud of are not peer reviewed in any fashion (e.g., standards documents).  

I thus simply organize all of my publications according to categories and try to include enough information that people from different fields may at least understand that there is a culture gap.  The current categories in my CV are:


Journal Articles
Book Chapters &amp; Theses 
Peer-Reviewed Conference Articles
Peer-Reviewed Conference Abstracts
Workshops, Symposia, and Seminars
Published Whitepapers and Technical Reports


This allows me to distinguish between conferences that people should take seriously ("Peer-Reviewed Conference Articles") and those which they should view as "light weight" ("Peer-Reviewed Conference Abstracts").  Conference poster presentations that haven't even received meaningful peer review I don't even list at this point, though at an earlier stage I would have put them down as another category.
