I thought I read a different email saying that there will be a track about the 50th anniversary. But cannot find any details or reference to it now. Does anyone have information about Unix 50th celebration(s)? Is it time for paper submissions? ... ==== If you mean for the 2019 USENIX Annual Technical Conference, the CFP is https://www.usenix.org/conference/atc19/call-for-papers The submission deadline is about three weeks away, on 2019-01-10. I see nothing explicit about a UNIX 50th celebration, alas. At least one program-committee member is on this list; perhaps more information will appear. Or there's a contact address for the program co-chairs on the web page cited above. Norman Wilson Toronto ON
